For example, an apparatus for performing a game using an output from a direction instruction input unit of a game controller operated by a player is disclosed (for example, see Patent Document 1).

Moving.

  However, the game device disclosed in Patent Document 1 corrects the content of the movement control of the player character determined by the direction instruction input means (joystick 37) by pressing the button (R1 button 38). The operation of the player becomes complicated. Further, the game device disclosed in Patent Document 1 is not an interface that effectively makes the player feel a direct feeling of game input to the virtual game world. For example, since the game device disclosed in Patent Document 1 inputs both the movement direction and the movement amount of the player character in the virtual game world by an operation using the direction instruction input means, the operation is performed only with the fingertip of the player. , I can not get a direct feeling of game input.

  Therefore, an object of the present invention is to solve at least one of the above-described problems, and to control the movement control of the player character in various ways with intuitive and easy operations, or to achieve a direct feeling of game input. It is providing the game system and game program which make you feel it.

  In order to achieve the above object, the present invention employs the following configuration. Note that the reference numerals in parentheses, step numbers, and the like indicate correspondence with the embodiments described later in order to help understanding of the present invention, and do not limit the scope of the present invention.

  The first invention is a game controller (7, 76) having a housing (77) that a player can hold with one hand, a game device (5) connected to the game controller, and detection for detecting the attitude of the housing. A game system (3) including a section (701). At least the game controller includes a direction instruction section (78a). The direction instruction section is provided in the housing and is provided for inputting a direction instruction. The game device includes movement vector control means (S43), correction means (S46, S52), and movement control means (S21). The movement vector control means determines the movement vector of the object (PC) appearing in the virtual game world according to the operation of the direction instruction unit. The correction means corrects the movement vector determined by the movement vector control means in accordance with the change in attitude of the housing from the reference attitude based on the detection by the detection unit. The movement control means controls the movement of the object in the virtual game world based on the movement vector corrected by the correction means. Note that the direction instruction unit may be, for example, a joystick, a cross key, or a plurality of button keys (each direction is assigned to each).

The movement vector control means determines at least the moving direction of the object in the virtual game world, and may further determine the movement amount in the virtual game world. The correction means corrects the movement vector determined by the movement vector control means. However, the correction means may correct the movement direction determined by the movement vector control means, or when the movement vector control means also determines the movement amount. The movement amount may be corrected. That is, the following variations can be considered.
The movement vector control means determines the movement direction, and the correction means corrects the movement direction.
The movement vector control means determines the movement direction and movement amount, and the correction means corrects the movement direction.
The movement vector control means determines the movement direction and movement amount, and the correction means corrects the movement amount.
The movement vector control means determines the movement direction and movement amount, and the correction means corrects the movement direction and movement amount.
A three-dimensional virtual game space, in which the movement vector control means determines a two-dimensional movement component (typically the amount of movement in two virtual horizontal directions), and the correction means determines the remaining one-dimensional movement component (typical The amount of movement in the virtual vertical direction is determined.

  Instead of the “movement amount” described above, “movement speed” or “movement acceleration” may be used.

  The detection unit includes a predetermined sensor, and the correction unit determines a posture change from the reference posture of the housing based on the output value of the sensor and corrects the movement vector. The correction unit determines a change in the posture of the housing from the reference posture. More specifically, the correction unit determines that the housing has rotated around the predetermined axis from the reference posture. The predetermined axis may be a predetermined axis of the housing or a predetermined axis in the real world. That is, the correcting means may determine that the housing has rotated around a predetermined axis of the housing, or may determine that the housing has rotated around a predetermined axis in the real world. For the former, for example, rotation (roll) around the front / rear axis of the housing (eg, around the long axis of the housing), rotation (pitch) around the left / right axis of the housing (eg, around the left / right short axis of the housing), vertical axis of the housing Rotation (yaw) around (for example, around the upper and lower short axes of the housing) may be determined. For the latter, for example, rotation around the horizontal axis or rotation around the vertical axis may be determined. The correcting means may calculate the rotation angle of the housing from the reference posture, but this is not essential. For example, when the gravitational acceleration applied to the predetermined axis direction is detected by the acceleration sensor as in the embodiment described later, the predetermined axis is determined from the reference posture based on the detected acceleration magnitude and direction without calculating the rotation angle. It can be determined that the housing has rotated around.

  Typically, the detection unit is a sensor fixed to the housing. As this sensor, a sensor (acceleration sensor, tilt sensor) that outputs data according to a tilt with respect to the direction of gravity (hereinafter simply referred to as “tilt”), a sensor (magnetic sensor) that outputs data according to a direction, a rotation A sensor (gyro sensor) that outputs data corresponding to the exercise can be used. Further, the acceleration sensor and the gyro sensor may be not only those that can detect multiple axes but also those that detect one axis. Further, these sensors may be combined to perform more accurate detection. A camera fixed to the housing can be used as the sensor. In this case, since the captured image captured by the camera changes in accordance with the change in the attitude of the housing, the change in the attitude from the reference attitude of the housing can be determined by analyzing this image.

  In addition, the detection unit may be separately provided outside the housing depending on the type of sensor. As an example, it is possible to determine a change in posture from the reference posture of the housing by photographing the housing from the outside of the housing with a camera as a sensor and analyzing the image of the housing imaged in the captured image. . Furthermore, a system in which a unit fixed to the housing and a unit separately provided outside the housing may be used. In this example, a light emitting unit is separately provided outside the housing, and light from the light emitting unit is photographed by a camera fixed to the housing. By analyzing the captured image captured by the camera, it is possible to determine a change in posture from the reference posture of the housing. Another example is a system in which a magnetic field generator is separately provided outside the housing and a magnetic sensor is fixed to the housing.

  As described above, the correcting means may determine that the housing has rotated around a predetermined axis of the housing (first correcting means), or that the housing has rotated around the predetermined axis in the real world. May be determined (second type correction means).

(1) Case of First Type Correction Unit First, an example in which an acceleration sensor is fixed to a housing will be described. As a simple example, acceleration generated in a predetermined direction of the housing is detected by an acceleration sensor. Then, by analyzing the change in the gravitational acceleration component using the acceleration detected by the acceleration sensor, it is possible to determine that the housing has rotated around an axis orthogonal to the gravitational acceleration direction. For example, it is possible to determine that the housing has rotated about the left and right axes of the housing by detecting the acceleration generated in the vertical direction of the housing and analyzing the change in the vertical component of the gravitational acceleration.

  Here, when using an acceleration sensor, gravitational acceleration detection is applied to the rotation of the housing where the inclination of the detection axis of the acceleration sensor does not change, such as the case where the detection axis of the acceleration sensor coincides with the rotation axis in the change in the attitude of the housing. Since the axial component does not change, it is difficult to determine the rotation of the housing. However, if the detection axis of the acceleration sensor does not coincide with the rotation axis in the attitude change of the housing (typically, such as an attitude change in which the detection axis of the acceleration sensor changes its inclination along the vertical plane) Since the output value for the detection axis changes due to the gravitational acceleration, the rotation of the housing can be determined.

  In the field of games to which the present invention is applied, it is sufficient that the correct game processing is performed when the game developer operates according to the correct operation method determined in advance, and other operations are performed. Even if correct game processing is not performed, there is no particular problem. Accordingly, in the game instruction manual, game screen, and the like, if a method for changing the attitude of the housing (more specifically, which axis to rotate around) is instructed as a correct operation method, the player can The housing is rotated according to the instruction. That is, it is sufficient if the attitude of the housing can be determined on the assumption of a certain rotation operation. Note that if the player performs an operation that deviates from the instructed operation, the attitude of the housing cannot be accurately determined. However, if the deviating degree is within an allowable range, the game processing is roughly correct. A processing result is obtained. Further, since the game apparatus is often not required to have much accuracy, it has sufficient practicality even in such a case.

  In the case of using an acceleration sensor, not only the gravitational acceleration acting on the housing but also the acceleration acting according to the movement of the housing is detected, but the acceleration detected according to the movement is detected by processing known to those skilled in the art. It is possible to remove. For example, as a simple example, when the acceleration value detected by the acceleration sensor indicates a value (or a sufficiently large value) greater than the gravitational acceleration, it is determined that the detected acceleration value does not indicate the gravitational acceleration. It is good also as a process which removes. Further, only when the variation in the acceleration value detected by the acceleration sensor is small, the detected acceleration value may indicate gravitational acceleration, and the processing may be adopted for posture analysis. Further, the high frequency component of the acceleration value detected by the acceleration sensor may be removed. Further, in the case of a game that does not require the housing to be moved violently, it is not necessary to perform a process for removing the acceleration acting according to the movement of the housing. This is because even if an acceleration corresponding to the movement of the housing is detected, if the player does not move the housing violently, a correct result can be obtained to some extent and it has sufficient practicality.

  In addition, when using the acceleration sensor capable of multi-axis detection and using the acceleration value generated in each of the multi-axis directions, the rotation angle of the housing from the reference posture can be calculated to make a more detailed determination. Is possible. For example, the rotation angle of the housing can be calculated by performing a predetermined calculation process using the values of acceleration in two axial directions detected by the acceleration sensor. Typically, arithmetic processing using a trigonometric function, such as substituting the values of acceleration in two axial directions into the arc tangent function, can be used for calculating the rotation angle of the housing.

  When an acceleration sensor capable of multi-axis detection is used, it is possible to determine which detection axis the housing has rotated based on which detection axis direction acceleration changes. In addition, when using an acceleration sensor that detects accelerations in three axial directions, for example, by performing arithmetic processing using the acceleration values in the first axial direction and the acceleration values in the second axial direction, It can be determined that the housing has rotated about the third axis. Further, it is possible to determine that the housing has rotated around the second axis by performing arithmetic processing using the acceleration value in the first axial direction and the acceleration value in the third axial direction. .

  When the housing is rotated in real space, centrifugal force is generated in the housing. The acceleration sensor may detect the centrifugal force and use it to determine the change in the attitude of the housing. That is, for example, when the acceleration sensor detects that acceleration has occurred in a certain direction of the housing, it can be determined that the housing may have rotated about an axis extending in a direction orthogonal thereto.

  Next, a case where the gyro sensor is fixed to the housing will be described. In this case, when the attitude of the housing is changed (that is, when the housing is rotated around a predetermined axis in the local coordinate system), the gyro sensor directly detects the rotation and outputs angular velocity data. Then, based on the output angular velocity data, it is possible to determine the change in the posture of the housing from the reference posture. More specifically, the change in the housing rotation angle can be determined using the angular velocity data. More typically, it is possible to determine a change in rotation angle around the front and rear axes of the housing, a change in rotation angle around the left and right axes of the housing, and / or a change in rotation angle around the vertical axis of the housing. is there. Further, by setting the rotation angle of the housing in the initial state, the rotation angle around the front and rear axes of the housing, the rotation angle around the left and right axes of the housing, and / or the rotation angle around the vertical axis of the housing is determined. It is possible.

(2) In the case of the second type of correction means Typically, an acceleration sensor capable of detecting acceleration in each of the three axial directions is fixed to the housing, and based on the acceleration value generated in each axial direction, By determining the direction of gravity, it is possible to determine the rotation angle of the housing around the horizontal axis. Alternatively, for example, for an acceleration sensor that can detect accelerations in three axial directions, a combined vector is calculated from the acceleration value in the first axial direction and the acceleration value in the second axial direction. It is also possible to determine the rotation angle of the third axis around the horizontal axis from the two-dimensional vector composed of the magnitude of the combined vector and the acceleration value in the third axis direction. Alternatively, it is possible to determine the rotation angle around the vertical axis by providing the azimuth sensor in the housing.

  The correction unit may correct the movement vector by a predetermined amount when the amount of change in posture from the reference posture reaches the threshold, or change the amount of correction of the movement vector according to the amount of change in posture. It may be something to let you. More specifically, the correction amount of the movement vector may be increased as the posture change amount increases.

  Further, the correcting means may correct the movement vector so that the amount of movement of the object in the predetermined direction in the virtual game world increases in accordance with the rotation of the housing around the predetermined axis. Here, the “predetermined direction in the virtual game world” may be a predetermined direction in the world coordinate system in the virtual game world, a predetermined direction in the local coordinate system of the object, or in the viewpoint coordinate system. It may be in a predetermined direction. Further, the predetermined direction may be determined based on “the direction in which the object moves when the front direction is instructed by the direction instruction unit”. Typically, the rotation of the housing about the left and right axis of the housing is determined, and based on the determination, the amount of movement of the object in the forward direction (forward and / or backward direction in the local coordinate system) is corrected. (More specifically, if the housing is rotated to tilt forward, the amount of forward movement of the object is corrected and / or the housing is rotated to tilt backward. Correct so that the amount of backward movement of the object increases.) Further, the rotation of the housing around the front and rear axes of the housing may be determined, and the amount of movement of the object in the left-right direction (the left-right direction in the local coordinate system) may be corrected based on the determination. Further, it may be determined that the front-rear axis (or vertical axis) of the housing has rotated around the horizontal axis, and based on the determination, the amount of forward movement of the object may be corrected. Further, it may be determined that the left and right axes of the housing are rotated around the horizontal axis, and the amount of movement of the object in the left and right direction may be corrected based on the determination.

  The above-mentioned “forward direction of the object” means (A) the direction in which the object is facing (typically, the local coordinate of the object or the Z-axis direction of the camera coordinate), or (B) the moving direction of the object. ("The direction in which the object moves in response to an instruction input in the forward direction of the direction indicating unit"). When the object moves in the direction in which the object is directed in response to the forward direction input from the direction indicating unit, (A) and (B) are the same.

  The movement vector control means determines a movement vector for moving the object in the “forward direction of the object” in response to an instruction input in the forward direction of the direction indicating unit, and “ A movement vector for moving the object in the direction opposite to the “front direction” is determined, and a movement vector for moving the object in the left-right direction orthogonal to the “front direction of the object” is determined according to the input instruction in the left-right direction of the direction indicating unit. . The “left / right direction” may be defined in the left / right direction in the local coordinate system or in the left / right direction in the world coordinate system.

  The “forward direction of the object” may be a fixed direction in the world coordinate system, or may be changed according to an instruction input from the direction instruction unit. In the latter case, when the movement vector of the object is determined, the direction of the movement vector is typically set to a new forward direction.

  Further, the correction means may determine the rotation of the housing around one axis, or may determine the rotation of the housing around a plurality of axes. In the latter case, “a predetermined direction in the virtual game world” is set for each axis. That is, the movement amount of the object in the direction A in the virtual game world is corrected according to the rotation of the housing around the axis A, and the movement amount of the object in the direction B in the virtual game world is corrected according to the rotation of the housing around the axis B. (Axis A and B are different, and direction A and direction B are different). Here, it is preferable that the axis A and the axis B are set to be orthogonal to each other, and the direction A and the direction B are set to be orthogonal to each other. Note that the rotation of the housing may be determined for three or more axes, that is, the amount of movement of the object in the direction C may be corrected according to the rotation of the housing around the axis C.

Further, functions as a minus button, a home button, a plus button, and the like are assigned to the operation buttons 72e to 72g. Each of these operation buttons 72b to 72g is assigned a function according to a game program executed by the game apparatus 3, and will be described in detail later. In the arrangement example shown in FIG. 5, the operation buttons 72 b to 72 d are arranged side by side along the center front-rear direction on the upper surface of the housing 71. Further, the operation buttons 72e to 72g are arranged in parallel between the operation buttons 72b and 72d along the left-right direction of the upper surface of the housing 71. The operation button 72f is a type of button whose upper surface is buried in the upper surface of the housing 71 and is not accidentally pressed by the player.

An operation button 72h is provided on the front surface side of the cross key 72a on the upper surface of the housing 71. The operation button 72h is a power switch for remotely turning on / off the game apparatus 5 main body. This operation button 72h is also a type of button whose upper surface is buried in the upper surface of the housing 71 and that the player does not accidentally press.

  A plurality of LEDs 702 are provided on the rear surface side of the operation button 72 c on the upper surface of the housing 71. Here, the controller 7 is provided with a controller type (controller identification number) to distinguish it from other controllers 7. For example, the LED 702 is used to notify the player of the controller type currently set in the controller 7. Specifically, when transmitting transmission data from the core unit 70 to the communication unit 6, among the plurality of LEDs 702, the LED corresponding to the type is lit according to the controller type.

  Further, on the upper surface of the housing 71, a sound release hole is formed between the operation button 72b and the operation buttons 72e to 72g for emitting sound from a speaker (speaker 706 in FIG. 7) described later to the outside.

  On the other hand, a recess is formed on the lower surface of the housing 71. As will be described later, the recess on the lower surface of the housing 71 is formed at a position where the player's index finger or middle finger is positioned when the player holds the core unit 70. An operation button 72i is provided on the inclined surface of the recess. The operation button 72i is, for example, an operation unit that functions as a B button, and is used for a shot trigger switch or a player switching operation in a soccer game.

  An imaging element 743 that constitutes a part of the imaging information calculation unit 74 is provided on the front surface of the housing 71. Here, the imaging information calculation unit 74 is a system for analyzing the image data captured by the core unit 70, discriminating a place where the luminance is high, and detecting the position of the center of gravity or the size of the place, For example, since the maximum sampling period is about 200 frames / second, even a relatively fast movement of the core unit 70 can be tracked and analyzed. The detailed configuration of the imaging information calculation unit 74 will be described later. A connector 73 is provided on the rear surface of the housing 71. The connector 73 is a 32-pin edge connector, for example, and is used for fitting and connecting with the connector 791 of the connection cable 79.

  Here, in order to make the following description concrete, a coordinate system set for the core unit 70 is defined. As shown in FIGS. 5 and 6, XYZ axes orthogonal to each other are defined with respect to the core unit 70. Specifically, the longitudinal direction of the housing 71 that is the front-rear direction of the core unit 70 is the Z axis, and the front surface (surface on which the imaging information calculation unit 74 is provided) of the core unit 70 is the Z axis positive direction. In addition, the vertical direction of the core unit 70 is defined as the Y axis, and the upper surface (surface on which the operation buttons 72a are provided) of the housing 71 is defined as the Y axis positive direction. Further, the left-right direction of the core unit 70 is taken as the X axis, and the right side surface (side face shown in FIG. 5 but not shown in FIG. 6) is taken as the X-axis positive direction.

  Next, the internal structure of the core unit 70 will be described with reference to FIGS. 7 and 8. FIG. 7 is a perspective view of the state in which the upper housing (a part of the housing 71) of the core unit 70 is removed as viewed from the rear side. FIG. 8 is a perspective view of the state in which the lower housing (a part of the housing 71) of the core unit 70 is removed as seen from the front side. Here, the substrate 700 shown in FIG. 8 is a perspective view seen from the back surface of the substrate 700 shown in FIG.

  In FIG. 7, a substrate 700 is fixed inside the housing 71, and operation buttons 72a to 72h, an acceleration sensor 701, an LED 702, an antenna 754, and the like are provided on the upper main surface of the substrate 700. These are connected to the microcomputer 751 and the like (see FIGS. 8 and 11) by wiring (not shown) formed on the substrate 700 and the like. Further, the core unit 70 functions as a wireless controller by a wireless module 753 (see FIG. 11) and an antenna 754 (not shown). A quartz oscillator (not shown) is provided inside the housing 71, and generates a basic clock for the microcomputer 751, which will be described later. A speaker 706 and an amplifier 708 are provided on the upper main surface of the substrate 700. Since the acceleration sensor 701 is provided not at the center of the substrate 700 but at the periphery, in addition to the change in the direction of gravitational acceleration according to the rotation about the longitudinal direction of the core unit 70, the component due to the centrifugal force Since the included acceleration can be detected, the rotation of the core unit 70 can be determined with good sensitivity from the detected acceleration data by a predetermined calculation.

  On the other hand, in FIG. 8, an imaging information calculation unit 74 is provided at the front edge on the lower main surface of the substrate 700. The imaging information calculation unit 74 includes an infrared filter 741, a lens 742, an imaging element 743, and an image processing circuit 744 in order from the front of the core unit 70, and is attached to the lower main surface of the substrate 700. A connector 73 is attached to the rear edge on the lower main surface of the substrate 700. Further, a sound IC 707 and a microcomputer 751 are provided on the lower main surface of the substrate 700. The sound IC 707 is connected to the microcomputer 751 and the amplifier 708 through wiring formed on the substrate 700 or the like, and outputs an audio signal to the speaker 706 via the amplifier 708 according to the sound data transmitted from the game apparatus body 5. A vibrator 704 is attached on the lower main surface of the substrate 700. The vibrator 704 is, for example, a vibration motor or a solenoid. Since the vibration is generated in the core unit 70 by the operation of the vibrator 704, the vibration is transmitted to the hand of the player holding it, and a so-called vibration-compatible game can be realized. Since the vibrator 704 is arranged slightly forward of the housing 71, the housing 71 vibrates greatly when the player is holding it, and it is easy to feel the vibration.

  The subunit 76 will be described with reference to FIGS. 9 and 10. FIG. 9 is a perspective view showing an example of the subunit 76. FIG. 10 is a perspective view showing a state in which the upper casing (a part of the housing 77) of the subunit 76 shown in FIG. 9 is removed.

  In FIG. 9, the subunit 76 has a housing 77 formed by plastic molding, for example. The housing 77 has a streamlined three-dimensional shape in which the front-rear direction is the longitudinal direction and the head portion that is the thickest part of the subunit 76 is formed in the front. The housing 77 is large enough to be grasped by one hand of an adult or a child as a whole. That's it. Furthermore, the housing 77 of the subunit 76 can be gripped so as to be wrapped with fingers other than the palm of one hand and thumb of the player, and the player's thumb is positioned on the stick 78a when the grip is held. The shape is designed.

  A stick 78 a is provided in the vicinity of the thickest portion on the upper surface of the housing 77. The stick 78a is an operation unit that detects a tilt direction (and additionally an amount of tilt) by tilting a tiltable stick that protrudes from the upper surface of the housing 77, and outputs an operation signal accordingly. For example, the player can specify an arbitrary direction and position by tilting the tip of the stick in an arbitrary direction of 360 °, and can instruct the moving direction of a player character or the like appearing in the virtual game world, or the moving direction of the cursor Can be instructed. Further, the player can instruct the amount of movement of the player character, cursor, etc., by the amount of tilt of the stick 78a.

  The stick 78a is an operation unit that outputs an operation signal in response to a player's direction input operation, but may be an operation unit of another mode. For example, instead of the stick 78a, a composite switch that combines the above-described push switch having a four-way operation portion in a ring shape and a center switch provided at the center thereof may be provided. In addition, an operation unit that outputs an operation signal corresponding to the sliding direction by sliding a horizontally movable disk-shaped member may be provided instead of the stick 78a. Further, a touch pad may be provided instead of the stick 78a. Further, an operation unit that outputs an operation signal in accordance with a switch pressed by the player may be provided instead of the stick 78a for switches indicating at least four directions (front, rear, left, and right).

  A plurality of operation buttons 78d and 78e are provided on the front surface of the housing 77 of the subunit 76. The operation buttons 78d and 78e are operation units that output operation signals assigned to the operation buttons 78d and 78e when the player presses the head of the button. For example, functions as an X button and a Y button are assigned to the operation buttons 78d and 78e. These operation buttons 78d and 78e are assigned respective functions according to the game program executed by the game apparatus 3, but are not directly related to the description of the present invention, and thus detailed description thereof is omitted. In the arrangement example shown in FIG. 9, the operation buttons 78 d and 78 e are arranged side by side along the vertical direction of the front surface of the housing 77.

  In FIG. 10, a substrate is fixed inside the housing 77, and a stick 78a and an acceleration sensor 761 are provided on the upper main surface of the substrate. These are connected to the connection cable 79 via wiring (not shown) formed on the substrate or the like. The acceleration sensor 761 is preferably disposed at the center portion of the housing 77 in the longitudinal direction and the center portion in the short direction. In addition, when the player holds the housing 77 so as to wrap the housing 77 with fingers other than the palm of one hand and the thumb, it is preferable that the player is disposed in a space surrounded by the palm and the finger (preferably substantially at the center of the space).

  Here, in order to make the following description concrete, a coordinate system set for the subunit 76 is defined. As shown in FIG. 9, XYZ axes orthogonal to each other are defined for the subunit 76. Specifically, the longitudinal direction of the housing 77, which is the front-rear direction of the subunit 76, is taken as the Z axis, and the front surface (surface on which the operation buttons 78d and 78e are provided) of the subunit 76 is taken as the positive Z axis direction. The vertical direction of the subunit 76 is defined as the Y axis, and the upper surface direction of the housing 77 (the direction in which the stick 78a protrudes) is defined as the Y axis positive direction. Further, the left-right direction of the subunit 76 is taken as the X-axis, and the right side surface (side surface not shown in FIG. 9) direction of the housing 77 is taken as the positive X-axis direction.

  Next, the internal configuration of the controller 7 will be described with reference to FIG. FIG. 11 is a block diagram showing the configuration of the controller 7.

In FIG. 11, the core unit 70 includes a communication unit 75 in addition to the above-described operation unit 72, imaging information calculation unit 74, acceleration sensor 701, vibrator 704, speaker 706, sound IC 707, and amplifier 708. Yes. Further, the subunit 7 6 is provided with an operation unit 78 and the acceleration sensor 761 described above, via the connection cable 79 and connectors 791 and 73 are connected to the microcomputer 751.

  The imaging information calculation unit 74 includes an infrared filter 741, a lens 742, an imaging element 743, and an image processing circuit 744. The infrared filter 741 allows only infrared light to pass through from light incident from the front of the core unit 70. The lens 742 condenses the infrared light that has passed through the infrared filter 741 and outputs the condensed infrared light to the image sensor 743. The imaging element 743 is a solid-state imaging element such as a CMOS sensor or a CCD, for example, and images the infrared rays collected by the lens 742. Therefore, the image sensor 743 captures only the infrared light that has passed through the infrared filter 741 and generates image data. Image data generated by the image sensor 743 is processed by an image processing circuit 744. Specifically, the image processing circuit 744 processes the image data obtained from the image sensor 743 to detect high-luminance portions, and transmits processing result data indicating the result of detecting their position coordinates and area to the communication unit 75. Output to. The imaging information calculation unit 74 is fixed to the housing 71 of the core unit 70, and the imaging direction can be changed by changing the direction of the housing 71 itself.

  The core unit 70 preferably includes a triaxial (X, Y, Z axis) acceleration sensor 701. The subunit 76 preferably includes a triaxial (X, Y, Z axis) acceleration sensor 761. The three-axis acceleration sensors 701 and 761 detect linear acceleration in three directions, that is, the up-down direction, the left-right direction, and the front-rear direction (the XYZ axis directions described above). In other embodiments, depending on the type of control signal used in the game process, biaxial acceleration detection that detects only linear acceleration along each of the vertical and horizontal directions (or other paired directions). A uniaxial acceleration detecting means for detecting only linear acceleration along any one of the means may be used. For example, the 1-axis to 3-axis acceleration sensors 701 and 761 may be of a type available from Analog Devices, Inc. or ST Microelectronics NV. . The acceleration sensors 701 and 761 are preferably of a capacitive type (capacitive coupling type) based on a MEMS (Micro Electro Mechanical Systems) technique in which silicon is micromachined. However, the 1-axis to 3-axis acceleration sensors 701 and 761 may be provided by using the existing acceleration detecting technology (for example, piezoelectric method or piezoresistive method) or other appropriate technology developed in the future.

  As known to those skilled in the art, the acceleration detecting means used in the acceleration sensors 701 and 761 can detect only acceleration (linear acceleration) along a straight line corresponding to each axis of the acceleration sensor. . That is, the direct outputs from the acceleration sensors 701 and 761 are signals indicating linear acceleration (static or dynamic) along each of the first to third axes. Therefore, the acceleration sensors 701 and 761 cannot directly detect physical characteristics such as movement, rotation, rotational movement, angular displacement, inclination, position, or posture along a non-linear (eg, arc) path. Can not.

  However, based on acceleration signals output from the acceleration sensors 701 and 761, a computer such as a processor of the game device (for example, the CPU 30), a controller 7 or a processor of the subunit 76 (for example, the microcomputer 751) performs processing. One skilled in the art will readily understand from the description herein that additional information regarding the core unit 70 and subunit 76 can be inferred or calculated (determined).

  For example, when processing is performed on the computer side on the assumption that the core unit 70 and the subunit 76 on which the acceleration sensors 701 and 761 are mounted are in a static state (that is, the acceleration detected by the acceleration sensors 701 and 761 is a gravitational acceleration). If the core unit 70 and the subunit 76 are actually in a static state, the posture of the core unit 70 and the subunit 76 is inclined with respect to the direction of gravity based on the detected acceleration. It is possible to know whether or not it is tilted. Specifically, when the detection axes of the acceleration sensors 701 and 761 are oriented vertically downward, the core unit 70 is determined only by whether 1G (gravity acceleration) is acting in the detection axis direction. In addition, it is possible to know whether or not the subunit 76 is inclined with respect to the vertically downward direction. Further, it can be determined how much the core unit 70 and the subunit 76 are inclined with respect to the vertical downward direction by the magnitude of the acceleration acting in the detection axis direction. In the case of the acceleration sensors 701 and 761 capable of detecting the acceleration in the multi-axis direction, the core unit 70 is further processed in the gravity direction by further processing the acceleration signals detected for the respective axes. It is possible to know in detail how much the subunit 76 is inclined. In this case, the processor may perform the process of calculating the tilt angle data of the core unit 70 and the subunit 76 based on the outputs from the acceleration sensors 701 and 761, but the process of calculating the tilt angle data. It is good also as a process which estimates the inclination condition of the approximate core unit 70 and the subunit 76 based on the output from the acceleration sensors 701 and 761 without performing. In this way, by using the acceleration sensors 701 and 761 in combination with the processor, the inclination, posture, or position of the core unit 70 and the subunit 76 can be determined.

  On the other hand, when it is assumed that the acceleration sensors 701 and 761 are in a dynamic state, the acceleration sensors 701 and 761 detect acceleration corresponding to the movement of the acceleration sensors 701 and 761 in addition to the gravitational acceleration component. Therefore, if the gravitational acceleration component is removed by a predetermined process, the movement directions of the core unit 70 and the subunit 76 can be known. Specifically, when the core unit 70 and the subunit 76 including the acceleration sensors 701 and 761 are dynamically accelerated and moved by the player's hand, the acceleration signals generated by the acceleration sensors 701 and 761 are processed. Thus, various movements and / or positions of the core unit 70 and the subunit 76 can be calculated. Even if it is assumed that the acceleration sensors 701 and 761 are in a dynamic state, if the acceleration corresponding to the movement of the acceleration sensors 701 and 761 is removed by a predetermined process, the core unit in the direction of gravity 70 and the inclination of the subunit 76 can be known.

  In another embodiment, the acceleration sensors 701 and 761 are built-in signal processing devices for performing desired processing on the acceleration signal output from the built-in acceleration detecting means before outputting the signal to the microcomputer 751. Alternatively, other types of dedicated processing apparatuses may be provided. For example, the built-in or dedicated processing device converts the detected acceleration signal into a corresponding tilt angle when the acceleration sensors 701 and 761 are for detecting static acceleration (for example, gravitational acceleration). You may do. Data indicating the acceleration detected by the acceleration sensors 701 and 761 is output to the communication unit 75.

  Here, when the player swings while holding the core unit 70 or the subunit 76, the swing start is accelerated and the swing end is decelerated. Accordingly, after the acceleration in the same direction as the direction in which the core unit 70 and the subunit 76 are swung is generated, the magnitude of the acceleration gradually decreases, and the direction in which the wave is swung at the end of the swing is reversed. Acceleration occurs in the direction of. On the other hand, generally, acceleration vectors (or positive and negative accelerations) output from the acceleration sensors 701 and 761 are vectors opposite to the acceleration directions of the core unit 70 and the subunit 76.

  In an example of another embodiment, instead of the acceleration sensors 701 and 761, a gyro sensor including at least one of a rotation element or a vibration element may be used. An example of a MEMS gyro sensor used in this embodiment is available from Analog Devices, Inc. Unlike the acceleration sensors 701 and 761, the gyro sensor can directly detect rotation (or angular velocity) about the axis of at least one gyro element incorporated therein. As described above, since the gyro sensor and the acceleration sensor are basically different from each other, it is necessary to appropriately change the processing to be performed on the output signals from these devices depending on which device is selected for each application. There is.

  Specifically, when the inclination or posture is calculated using a gyro sensor instead of the acceleration sensor, a significant change is made. That is, when the gyro sensor is used, the inclination value is initialized in the detection start state. Then, the angular velocity data output from the gyro sensor is integrated. Next, a change amount of the inclination from the initialized inclination value is calculated. In this case, the calculated inclination is a value corresponding to the angle. On the other hand, when the inclination is calculated by the acceleration sensor, the inclination is calculated by comparing the value of the component relating to each axis of the gravitational acceleration with a predetermined reference, so the calculated inclination can be expressed by a vector. Thus, it is possible to detect the absolute direction detected using the acceleration detecting means without performing initialization. In addition, the property of the value calculated as the inclination is an angle when a gyro sensor is used, but a vector when an acceleration sensor is used. Therefore, when a gyro sensor is used instead of the acceleration sensor, it is necessary to perform predetermined conversion in consideration of the difference between the two devices with respect to the tilt data. Since the characteristics of the gyroscope as well as the basic differences between the acceleration detection means and the gyroscope are known to those skilled in the art, further details are omitted here. While the gyro sensor has the advantage of being able to directly detect rotation, in general, the acceleration sensor has the advantage of being more cost effective than the gyro sensor when applied to a controller as used in this embodiment. Have.

  The communication unit 75 includes a microcomputer (microcomputer) 751, a memory 752, a wireless module 753, and an antenna 754. The microcomputer 751 controls the wireless module 753 that wirelessly transmits transmission data while using the memory 752 as a storage area during processing. The microcomputer 751 controls the operation of the sound IC 707 and the vibrator 704 in accordance with data from the game apparatus body 5 received by the wireless module 753 via the antenna 754. The sound IC 707 processes sound data transmitted from the game apparatus body 5 via the communication unit 75. Further, the microcomputer 751 activates the vibrator 704 in accordance with vibration data (for example, a signal for turning the vibrator 704 on or off) transmitted from the game apparatus body 5 via the communication unit 75. Further, identification number data uniquely set for each core unit 70 is stored in the memory 752 or the non-volatile storage means (not shown).

  An operation signal (core key data) from the operation unit 72 provided in the core unit 70, an acceleration signal (core acceleration data) from the acceleration sensor 701, and processing result data from the imaging information calculation unit 74 are output to the microcomputer 751. Is done. In addition, an operation signal (sub key data) from the operation unit 78 provided in the subunit 76 and an acceleration signal (sub acceleration data) from the acceleration sensor 761 are output to the microcomputer 751 via the connection cable 79. The microcomputer 751 temporarily stores the input data (core key data, sub key data, core acceleration data, sub acceleration data, and processing result data) in the memory 752 as transmission data to be transmitted to the communication unit 6. Here, the wireless transmission from the communication unit 75 to the communication unit 6 is performed at predetermined intervals, but since the game processing is generally performed in units of 1/60 seconds, it is shorter than that. It is necessary to collect and transmit data at periodic intervals. Specifically, the processing unit of the game is 16.7 ms (1/60 seconds), and the transmission interval of the communication unit 75 configured by Bluetooth (registered trademark) is 5 ms. When the transmission timing to the communication unit 6 arrives, the microcomputer 751 assigns a unique controller identification number to the controller 7 and outputs the transmission data stored in the memory 752 as a series of operation information to the wireless module 753. The wireless module 753 modulates the operation information using a carrier wave having a predetermined frequency based on, for example, Bluetooth (registered trademark) technology, and radiates the weak radio signal from the antenna 754. That is, the core key data from the operation unit 72 provided in the core unit 70, the sub key data from the operation unit 78 provided in the subunit 76, the core acceleration data from the acceleration sensor 701 provided in the core unit 70, the sub The sub acceleration data from the acceleration sensor 761 provided in the unit 76, the processing result data from the imaging information calculation unit 74, and the controller identification number are modulated into weak radio signals by the wireless module 753 and radiated from the core unit 70. . Then, the weak radio signal is received by the communication unit 6 of the game apparatus 3, and the weak radio signal is demodulated and decoded by the game apparatus 3, whereby a series of operation information (core key data, sub key data, core acceleration data, Sub-acceleration data and processing result data) and a controller identification number can be acquired. Then, the CPU 30 of the game apparatus 3 performs a game process based on the acquired operation information, the controller identification number, and the game program.

  As shown in FIG. 12, in order to play a game using the controller 7 in the game system 1, the player holds the core unit 70 with one hand (for example, the right hand) (see FIGS. 13 and 14). The subunit 76 is held with the other hand (for example, the left hand) (see FIG. 16). Then, the player holds the core unit 70 so that the front surface of the core unit 70 (the light entrance side of the light imaged by the imaging information calculation unit 74) faces the monitor 2. On the other hand, in the vicinity of the display screen of the monitor 2, two markers 8L and 8R are installed. These markers 8L and 8R each output infrared light toward the front of the monitor 2.

  When the player holds the core unit 70 so that the front surface thereof faces the monitor 2, infrared light output from the two markers 8 </ b> L and 8 </ b> R enters the imaging information calculation unit 74. Then, the imaging device 743 captures the incident infrared light through the infrared filter 741 and the lens 742, and the image processing circuit 744 processes the captured image. Here, the imaging information calculation unit 74 acquires the position and area information of the markers 8L and 8R by detecting infrared components output from the markers 8L and 8R. Specifically, the imaging information calculation unit 74 analyzes the image data captured by the imaging element 743, excludes images that cannot be infrared light from the markers 8L and 8R from the area information, and has a high luminance position. Are determined as the positions of the markers 8L and 8R, respectively. Then, the imaging information calculation unit 74 acquires the determined position coordinates, the center-of-gravity coordinates, and the like, and outputs them as the processing result data. By transmitting such processing result data to the game apparatus 3, the game apparatus 3 moves and postures the imaging information calculation unit 74 for the markers 8 </ b> L and 8 </ b> R, that is, the core unit 70, based on the position coordinates and the barycentric coordinates. An operation signal related to the position or the like can be obtained. Specifically, since the position of the high luminance point in the image transmitted from the communication unit 75 changes when the core unit 70 is moved, direction input and coordinate input corresponding to the change in the position of the high luminance point are performed. By performing the above, direction input and coordinate input along the moving direction of the core unit 70 can be performed.

  Thus, the game processing in the game apparatus 3 is performed by imaging the marker (in the embodiment, infrared light from the two markers 8L and 8R) fixedly installed by the imaging information calculation unit 74 of the core unit 70. In this case, it is possible to use processing result data related to the movement, posture, position, etc. of the core unit 70, and it becomes a more intuitive operation input that is different from the operation buttons and operation keys that press the button. Further, as described above, since the marker is installed in the vicinity of the display screen of the monitor 2, it is easy to convert the position relative to the marker into the movement, posture, position, etc. of the core unit 70 relative to the display screen of the monitor 2. It can be carried out. That is, the processing result data based on the movement, posture, position, etc. of the core unit 70 can be used as an operation input that directly acts on the display screen of the monitor 2.

  A state where the player holds the core unit 70 with one hand will be described with reference to FIGS. 13 and 14. FIG. 13 is an example of a state where the player holds the core unit 70 with the right hand as viewed from the front side of the core unit 70. FIG. 14 shows an example in which the player holds the core unit 70 with his right hand as viewed from the left side of the core unit 70.

  As shown in FIGS. 13 and 14, the core unit 70 has a size that can be gripped with one hand of an adult or a child as a whole. When the player's thumb is attached to the upper surface of the core unit 70 (for example, in the vicinity of the cross key 72a) and the player's index finger is applied to the concave portion (for example, in the vicinity of the operation button 72i) of the core unit 70, the front surface of the core unit 70 is obtained. The light incident port of the imaging information calculation unit 74 provided in is exposed in the forward direction of the player. Needless to say, such a gripping state with respect to the core unit 70 can be similarly performed even with the left hand of the player.

  Here, as shown in FIG. 15, the markers 8L and 8R each have a viewing angle θ1. Further, the image sensor 743 has a viewing angle θ2. For example, the viewing angles θ1 of the markers 8L and 8R are both 34 ° (half-value angle), and the viewing angle θ2 of the image sensor 743 is 41 °. When the markers 8L and 8R are both present in the viewing angle θ2 of the image sensor 743, and the image sensor 743 is present in the viewing angle θ1 of the marker 8L and in the viewing angle θ1 of the marker 8R, the game device The main body 5 determines the position of the core unit 70 using the position data regarding the high luminance point by the two markers 8L and 8R.

  On the other hand, when there is only one marker 8L or 8R in the viewing angle θ2 of the imaging device 743, or there is an imaging device 743 in either the viewing angle θ1 of the marker 8L or the viewing angle θ1 of the marker 8R. When this is done, the position of the core unit 70 is determined using the position data relating to the high luminance point by only one of the two markers 8L and 8R.

  Further, by using the output (core acceleration data) from the acceleration sensor 701 provided in the core unit 70 as described above, the inclination, posture, or position of the core unit 70 can be determined. That is, when the player moves the hand holding the core unit 70 up, down, left, and right, the core unit 70 functions as an operation input unit according to the movement and orientation of the player's hand.

  Next, a state where the player holds the subunit 76 with one hand will be described with reference to FIG. FIG. 16 shows an example in which the player holds the subunit 76 with his left hand as viewed from the right side of the subunit 76.

  As shown in FIG. 16, the subunit 76 has a size that can be grasped with one hand of an adult or a child as a whole. For example, the player's thumb is attached to the upper surface of the subunit 76 (for example, near the stick 78a), the player's index finger is attached to the front surface of the subunit 76 (for example, near the operation buttons 78d and 78e), and the player's middle finger, ring finger, and little finger It is possible to hold the subunit 76 so that is attached to the lower surface of the subunit 76. Needless to say, such a gripping state with respect to the subunit 76 can be similarly performed even with the right hand of the player. In this way, the subunit 76 can easily operate the operation unit 78 such as the stick 78a and the operation buttons 78d and 78e while being held by the player with one hand. As described above, the main body (housing 77) of the subunit 76 is formed in a shape and size that allows the player to grip the side periphery of the entire subunit 76 with one hand.

  Further, by using the output (sub acceleration data) from the acceleration sensor 761 provided in the subunit 76 as described above, the inclination, posture, or position of the subunit 76 can be determined. That is, when the player moves his / her hand holding the subunit 76 up / down / left / right, the subunit 76 functions as an operation input means corresponding to the movement and direction of the player's hand.

  An example of a game realized by applying the present invention is a soccer game played in a virtual game space. Hereinafter, the details of the game process performed in the game system 1 will be described using a soccer game as an example. FIG. 17 is a diagram showing main data stored in the main memory 33 of the game apparatus body 5.

  As shown in FIG. 17, in the main memory 33, operation information Da, controller identification number data Db, movement vector data Dc, posture vector data Dd, instruction coordinate data De, virtual space position coordinate data Df, instruction target player data Dg , Position data Dh, image data Di, and the like are stored. As will be described later, each controller 7 can control the movement of a specific player character by inputting the coordinates of the controller 7 in the manager mode or the temporary manager mode. Is called the target player. In addition to the data included in the information shown in FIG. 17, the main memory 33 stores data necessary for the game process, such as data related to objects appearing in the game and data related to the virtual game space. These data are data generated when the CPU 30 executes a game program stored on the optical disc 4.

  The operation information Da is a series of operation information transmitted as transmission data from the controller 7, and is updated to the latest operation information. The operation information Da includes first coordinate data Da1 and second coordinate data Da2 corresponding to the processing result data described above. The first coordinate data Da1 is coordinate data representing the position (position in the captured image) of one of the two markers 8L and 8R with respect to the captured image captured by the image sensor 743. The second coordinate data Da2 is coordinate data representing the position of the image of the other marker (position in the captured image). For example, the position of the marker image is represented by an XY coordinate system in the captured image.

  The operation information Da includes key data Da3, acceleration data Da4, and the like in addition to coordinate data (first coordinate data Da1 and second coordinate data Da2) as an example of processing result data obtained from the captured image. Specifically, the key data Da <b> 3 is core key data obtained from the operation unit 72 and subkey data obtained from the operation unit 78. The acceleration data Da4 is core acceleration data obtained from the acceleration sensor 701 and sub-acceleration data obtained from the acceleration sensor 761. The communication unit 6 provided in the game apparatus 3 receives operation information Da transmitted from the controller 7 at a predetermined interval, for example, every 5 ms, and is stored in a buffer (not shown) provided in the communication unit 6. Thereafter, the game processing interval is read, for example, every frame (1/60 seconds), and the latest information is stored in the main memory 33. In the operation information Da, not only the latest operation information but also operation information for a predetermined past time is stored as a history as necessary. Further, when the game apparatus body 5 is operated by the plurality of controllers 7, the operation information transmitted from each controller 7 is associated with each controller identification number and stored in the operation information Da.

  The controller identification number data Db describes a controller identification number that employs operation information for each operation team and operation mode described later. For example, the controller identification number data Db includes team A player mode controller identification number Db1, team A manager mode controller identification number Db2, team B player mode controller identification number Db3, and team B manager mode controller identification number Db2. An identification number Db4 and the like are described. The controller identification number data Db is obtained by transmitting identification number data (described above) stored in the core unit 70 from the core unit 70 and storing it. The controller identification number Db does not always have to be set all the time, and information indicating that the controller identification number Db has not been set is set for those not desired by the player. In addition, the team mode in which information indicating non-setting is set may be controlled by a computer. If the game has three or more teams, controller identification number data Db corresponding to the number of teams is set. If the game has no team concept, at least one player mode controller may be set. Note that the identification number data of one controller may be set in a plurality of controller identification number data Db. In this case, for example, the player mode process and the manager mode process can be executed by operating one controller.

  The movement vector data Dc is movement vector data indicating the direction and speed in which each player character or ball object appearing in the virtual game space moves in the virtual game space. For example, the movement vector data Dc includes movement vector data Dc1 of the player character PC, movement vector data Dc2 of the non-player character NPC, movement vector data Dc3 of the instruction target player, movement vector data Dc4 of the ball object B, and the like. . In this embodiment, the virtual game space is a three-dimensional space. However, it can be easily understood by those skilled in the art that this embodiment includes elements that can also be applied to a game in a two-dimensional space.

  The posture vector data Dd is data indicating the posture of the upper body of the player character PC in the virtual game space. For example, the posture vector data Dd describes vector data (posture vector data Vc) from the waist to the head of the player character PC in the player character coordinate system. This posture vector data Vc is a three-dimensional vector.

  The designated coordinate data De is data indicating designated coordinates based on the screen coordinate system of the monitor 2 obtained based on the first coordinate data Da1 and the second coordinate data Da2. For example, the designated coordinates are direction data indicating the direction from the first coordinate data Da1 to the second coordinate data Da2 (for example, vector data having the position of the first coordinate data Da1 as the start point and the position of the second coordinate data Da2 as the end point). ) Or the midpoint coordinate data indicating the midpoint between the first coordinate data Da1 and the second coordinate data Da2. Here, when the images of the two markers (markers 8L and 8R) are viewed as one target image, the midpoint coordinate data indicates the position of the target image. The virtual space position coordinate data Df is coordinate data indicating the virtual space position of the virtual game space corresponding to the indicated coordinates. The virtual space position coordinate data Df is calculated based on the designated coordinate data De, the parameters of the virtual camera, and the configuration data (terrain data and object position data) of the virtual space. When the game apparatus body 5 is operated by a plurality of controllers 7, the indicated coordinates and the virtual space position calculated based on the first coordinate data Da1 and the second coordinate data Da2 respectively transmitted from the controllers 7 are Each is associated with each controller identification number and stored in the designated coordinate data De and the virtual space position coordinate data Df.

  The instruction target player data Dg is data indicating an instruction target player of each controller 7. For example, the instruction target player data Dg includes data Dg1 indicating an instruction target player of the team A player mode controller 7, data Dg2 indicating an instruction target player of the team A manager mode controller 7, and a player mode controller of the team B 7 data Dg3 indicating the instruction target player 7 and data Dg4 indicating the instruction target player of the team B manager mode controller 7 are described.

  The position data Dh is coordinate data in the virtual game space that indicates the positions at which characters and objects appearing in the virtual game space are respectively arranged. The image data Di is image data for generating characters, objects, and backgrounds appearing in the virtual game space.

  Next, with reference to FIGS. 18 to 29, details of the game process performed in the game apparatus body 5 will be described. FIG. 18 is a flowchart showing a flow of game processing executed in the game apparatus body 5.

FIG. 28 is a diagram illustrating an example of a trajectory along which the ball object B moves. FIG. 29 is a diagram showing an example of the movement vector Vmnpc set for the non-player character NPC. In the flowcharts shown in FIG. 18 to FIG. 24, the processing in which the soccer game is executed in the virtual game space in the virtual game space will be mainly described, and other game processing not directly related to the present invention will be described in detail. Description is omitted. In FIG. 18 to FIG. 24, each step executed by the CPU 30 is abbreviated as “S”. The coordinate axes of the virtual game space shown in FIG. 25 are the X direction in the left-right direction (the horizontal direction and the direction in which the touch line extends), the Y direction in the vertical direction (vertical direction), and the depth direction (horizontal). The direction is the direction in which the goal line extends) is described as the Z direction.

  When the power of the game apparatus body 5 is turned on, the CPU 30 of the game apparatus body 5 executes a startup program stored in a boot ROM (not shown), thereby initializing each unit such as the main memory 33. Then, the game program stored in the optical disc 4 is read into the main memory 33, and the CPU 30 starts executing the game program. The flowchart shown in FIGS. 18-24 is a flowchart which shows the game process performed when CPU30 runs the said game program after the above process is completed.

  In FIG. 18, the CPU 30 performs an initial setting process for the game process (step 10), and advances the process to the next step. For example, in the soccer game, the player character is divided into team A and team B, and the game progresses, so that the player can operate the player character of any one team (referred to as team X). . The player can select an operation mode by a player mode in which the player character of team X is directly operated and a manager mode in which the player character of team X is comprehensively commanded. Note that it is not essential to provide both the player mode and the manager mode, and only the player mode or the manager mode may be used. Accordingly, in step 10 above, the CPU 30 distinguishes and manages each team and the controller 7 operated in each mode, so that the team A player mode controller identification number, the team A manager mode controller identification number, The B player mode controller identification number and the team B manager mode controller identification number are set and described in the controller identification number data Db.

  More specifically, a team (A or B) and a mode (player or manager) are selected on the menu screen displayed on the monitor 2 by operating the controller 7 to be used (in the case of a plurality of each), and the selection is performed. The identification number data stored in the controller 7 is set to the corresponding controller identification number Db. For example, when a team A is selected by operating a certain controller 7 and a player mode is selected, the identification number of the controller 7 is set to the player identification number Db1 of the team A. In step 10, the CPU 30 performs initial settings (game field setting, initial arrangement of each player character, ball object, etc.) before starting the soccer game, and each data described in the main memory 33. Update.

  Next, the CPU 30 determines whether or not to start the game (step 11). The conditions for starting the game include, for example, that a condition for starting the game is satisfied, and that the player has performed an operation for starting the game. The CPU 30 repeats the process of step 11 when the game is not started, and advances the process to the next step 12 when the game is started.

  Each process of step 12 to step 24 is a process that is repeated for each processing unit (for example, 1/60 seconds) of the above-described game, and is a process performed for each of team A and team B (team X). In the following description, processing performed for each of team A and team B is described as processing performed for team X.

  In step 12, the CPU 30 receives the operation information from the controller 7 (in the case of a plurality of each), and stores it in the operation information Da for each controller identification number. Next, the CPU 30 refers to the controller identification number data Db to determine whether or not the player mode controller identification number Db is set for the team X (step 13). And CPU30 advances a process to the following step 14, when the controller identification number Db for player modes is set about the team X. FIG. On the other hand, when the player mode controller identification number Db is not set for the team X, the CPU 30 proceeds to the next step 25.

  In step 14, the CPU 30 sets the movement vector Vmnpc of each non-player character NPC of the team X using a predetermined automatic movement algorithm, and stores it in the movement vector data Dc. Next, the CPU 30 performs subunit movement processing (step 15), pass processing (step 16), first shoot processing (step 17), second shoot processing (step 18), temporary supervision mode processing (step 19), and After the supervisor mode process (step 20), the process proceeds to step 21. Detailed processing performed in steps 15 to 20 will be described later.

  For example, as shown in FIG. 25, a player operates a player character PA belonging to team A (indicated by a white figure) in the player mode, and a computer-controlled player character PB belonging to team B (indicated by a solid figure). And a soccer game are assumed. In this case, the player directly operates one of the player characters PA (player character PA1 in FIG. 25) as the player character PC, and the other player character PA becomes the non-player character NPC. Further, the player characters PB are all non-player characters NPC. The team that one of the player characters keeps the ball object B is the attacking team (in FIG. 25, the player character PA1 keeps the ball object B, so the team A is the attacking team. ) And the other team is the defensive team (Team B in FIG. 25). Here, when the team X is the defensive side (when the team X is the team B) in the above step 14, the CPU 30 uses the position data of the player character (player character PA1) keeping the ball object B as a reference. The movement vector of the player character (player character PB1 in FIG. 25) of the team X (team B) arranged in the predetermined range is used as the posture vector (described later) of the player character holding the ball object B. Set accordingly. Specifically, in this embodiment, the CPU 30 projects the movement vector of the player character arranged in the predetermined range as “the posture vector of the player character (PA1) keeping the ball object B onto the virtual horizontal plane. The vector A (the X component is equal to the X component of the posture vector, the Y component is 0, and the Z component is equal to the Z component of the posture vector) ”is set. Note that the movement vector of the player character set by the automatic movement algorithm described above may be corrected (typically added) by the vector A.

On the other hand, step if the flop 1 3 No (i.e., if the controller 7 for players mode team X is not set), at step 25, CPU 30 may all competitors automatic movement vector Vmnpc predetermined character team X It is set using a movement algorithm and stored in movement vector data Dc (that is, since no player mode controller 7 is set for team X, all player characters of team X become non-player characters NPC). In step 25, as in step 14, the setting or correction of the movement vector of the player character arranged in the predetermined range is performed according to the posture vector. Next, the CPU 30 advances the process to step 21 through the supervisory mode process (step 20).

  In step 21, the CPU 30 moves each character or object in the virtual game space based on each movement vector data described in the movement vector data Dc, and displays a game image on the monitor 2. Next, the CPU 30 updates the movement vector data Dc by attenuating each movement vector data described in the movement vector data Dc by a predetermined amount (step 22). Then, the CPU 30 performs other processes performed in the soccer game such as a goal process, a foul process, and a player character PC switching process (step 23), and advances the process to the next step.

  Next, the CPU 30 determines whether or not to end the game (step 24). The conditions for ending the game include, for example, that a condition for game over is satisfied, and that the player has performed an operation for ending the game. The CPU 30 returns to step 12 when the game is not finished and repeats the process, and when the game is finished, the process according to the flowchart is finished.

  Next, with reference to FIG. 19, the detailed operation of the subunit movement process in step 15 will be described.

  In FIG. 19, the CPU 30 refers to the latest subkey data included in the operation information transmitted from the player mode subunit of the team X from the operation information Da (step 41), and advances the processing to the next step. Here, in step 12 above, the operation information Da stores the operation information transmitted from each controller 7 for each controller identification number, and the controller ID data Db contains the player X controller identification number for the player mode. Is described. Therefore, the CPU 30 can extract the operation information transmitted from the player mode subunit from the operation information Da, based on the player mode controller identification number of the team X described in the controller ID data Db.

  Next, the CPU 30 determines whether or not there is a direction instruction input from the player based on the sub key data of the player mode subunit referred to in the step 41 (step 42). As described above, the subunit 76 is provided with the stick 78a, and a direction instruction can be input by tilting the stick 78a that can be tilted by the player. Then, when there is a direction instruction input from the player, the CPU 30 proceeds to the next step 43. On the other hand, if there is no direction instruction input from the player, the CPU 30 proceeds to the next step 47.

  In step 43, the CPU 30 calculates the movement vector Vmpc of the player character PC of the team X based on the direction instruction input from the player mode subunit 76 of the team X, updates the movement vector data Dc, and performs processing. Proceed to the next step. For example, as shown in FIG. 26, a movement vector Vmpc is set as data indicating the moving direction and moving speed of the player character PC in the virtual game space. In step 43 described above, the CPU 30 determines the direction in the virtual game space determined in accordance with the tilt direction of the stick 78a with respect to the current movement vector Vmpc of the player character PC stored in the movement vector data Dc, and the stick. A new movement vector Vmpc having a magnitude corresponding to the tilt angle 78a is calculated. By this process, the player character PC of the team X operated by the player controls the moving direction and moving speed in the virtual game space by operating the stick 78a of the subunit 76 possessed by the player.

  Next, the CPU 30 refers to the latest sub acceleration data included in the operation information transmitted from the player mode subunit of the team X from the operation information Da (step 44). Then, the CPU 30 determines whether or not the acceleration in the positive Z-axis direction (see FIG. 9) indicated by the sub acceleration data is equal to or greater than a predetermined value (step 45). When the acceleration in the positive direction of the Z-axis is equal to or greater than a predetermined value, the CPU 30 increases the magnitude of the movement vector Vmpc of the player character PC in the team X determined in step 43 as described above using a predetermined algorithm. (For example, the player character PC is moved in accordance with the magnitude of acceleration in the positive direction of the Z axis, increased by a predetermined value, or multiplied by n (n is a value larger than 1)). The vector data Dc is updated (step 46), and the process proceeds to the next step 47. By the processing of step 46, the moving speed of the player character PC operated by the player in the virtual game space is determined by the player tilting the subunit 76 forward (that is, the Z-axis positive direction is lower than the Z-axis negative direction). (By making the direction point to). On the other hand, if the magnitude of acceleration in the Z-axis direction is less than the predetermined value, the CPU 30 proceeds to the next step 47 as it is. In step 45, it is determined whether or not the acceleration in the negative Z-axis direction is smaller than a predetermined value (minus value). If the determination is Yes, the magnitude of the movement vector Vmpc of the player character PC in the team X is determined. Decreasing by a predetermined algorithm (for example, decreasing according to the magnitude of the Z-axis negative direction, decreasing by a predetermined value, or m times (m is a value smaller than 1)) The movement vector data Dc of the player character PC may be updated.

  In step 47, the CPU 30 refers to the latest sub acceleration data included in the operation information transmitted from the player mode subunit of the team X from the operation information Da. Then, the CPU 30 calculates the posture vector Vc of the player character PC in the team X according to the sub acceleration data, updates the posture vector data Dd, and advances the processing to the next step.

  For example, as shown in FIG. 26, a posture vector Vc is set as data indicating the posture of the player character PC in the virtual game space. Here, the posture vector Vc is set based on the player character coordinate system. In the player character coordinate system, the front direction of the player character PC in the virtual game space is set as the Zp-axis direction (typically, the direction of the movement vector Vmpc of the player character PC is set as the Zp-axis direction. When the direction vector and the direction vector (forward vector) of the player character PC are controlled independently, the direction of the direction vector of the player character PC may coincide with the Zp-axis direction). The forward direction of the PC is the Zp-axis positive direction. Further, the left-right direction of the player character PC in the virtual game space is defined as the Xp-axis direction, and the right direction viewed from the player character PC is defined as the Xp-axis positive direction. Further, the vertical direction of the player character PC in the virtual game space is defined as the Yp-axis direction, and the upward direction is defined as the Yp-axis positive direction. The posture vector Vc is set as vector data from the waist of the player character PC toward the head. The posture vector Vc is typically vector data in the player character coordinate system.

  In step 48, the CPU 30 associates the acceleration in the X-axis direction (see FIG. 9) indicated by the sub-acceleration data with the Xp-axis direction of the player character coordinate system, and sets the acceleration in the Y-axis direction indicated by the sub-acceleration data as the player character coordinates. The posture vector Vc is calculated by associating with the Yp-axis direction of the system and associating the acceleration in the Z-axis direction indicated by the sub acceleration data with the Zp-axis direction of the player character coordinate system.

  For example, in step 48 described above, the posture of the player character PC is controlled according to the inclination of the subunit 76 as an example. In this case, specifically, the value in the Xp-axis direction of the posture vector data in the player character coordinate system is determined according to the acceleration value in the X-axis direction indicated by the sub acceleration data (typically in proportion). Then, according to the value obtained by inverting the sign of the acceleration in the Y-axis direction indicated by the sub acceleration data (typically proportionally), the value in the Yp-axis direction of the posture vector data in the player character coordinate system is determined, In accordance with the acceleration value in the Z-axis direction indicated by the sub-acceleration data (typically in proportion), the value in the Zp-axis direction of the posture vector data in the player character coordinate system is determined (each proportional constant is It ’s typically common but not limited to this.) More specifically, for example, the acceleration value in the X-axis direction indicated by the sub-acceleration data: the acceleration value in the Y-axis direction: the acceleration value in the Z-axis direction = the Xp-axis direction of the posture vector data in the player character coordinate system Value: Attitude vector data is determined so that the value in the Yp-axis direction of attitude vector data: The value in the Zp-axis direction of attitude vector data. Alternatively, the Xp-axis direction value of the posture vector data in the player character coordinate system is determined according to the X-axis direction acceleration value indicated by the sub-acceleration data, and the Z-axis direction acceleration value indicated by the sub-acceleration data is determined. Thus, the value in the Zp-axis direction of the posture vector data in the player character coordinate system may be determined, and the value in the Yp-axis direction of the posture vector data in the player character coordinate system may be constant.

  For example, in step 48 described above, the posture of the player character PC is controlled according to the movement (parallel movement) of the subunit 76 as an example. For example, when the player moves the subunit 76 in the right direction, acceleration in the X-axis positive direction is generated in the subunit 76 (when the player moves the subunit 76 in the right direction, this is output at the beginning of the movement. The acceleration in the positive X-axis direction may be detected, or the acceleration in the negative X-axis direction that is output when the movement is stopped may be detected. Then, the acceleration sensor 761 provided in the subunit 76 detects the acceleration in the positive direction of the X axis, and the subunit 76 transmits sub acceleration data indicating the acceleration to the game apparatus body 5. On the other hand, the CPU 30 calculates a new posture vector Vc by adding the Xp-axis positive direction vector to the posture vector Vc with the magnitude of the acceleration according to the acceleration in the X-axis positive direction indicated by the received sub acceleration data. To do. Then, the upper body of the player character PC is inclined in the positive direction of the Xp axis according to the newly calculated posture vector Vc. When the player moves the subunit 76 in the forward direction, acceleration in the positive direction of the Z axis is generated in the subunit 76. Then, the acceleration sensor 761 provided in the subunit 76 detects the acceleration in the Z-axis positive direction, and the subunit 76 transmits the sub-acceleration data indicating the acceleration to the game apparatus body 5. On the other hand, the CPU 30 calculates a new posture vector Vc by adding the Zp-axis positive direction vector to the posture vector Vc with the magnitude of the acceleration according to the acceleration in the Z-axis positive direction indicated by the received sub acceleration data. To do. Then, the upper body of the player character PC is inclined in the positive direction of the Zp axis according to the newly calculated posture vector Vc. By the processing in step 48, the posture of the player character PC operated by the player in the virtual game space changes according to the movement of the player moving the entire subunit 76.

  Here, in step 14 and step 25, the movement vector of the player character of the opponent team (for example, the player character PB1 shown in FIG. 25) arranged in the predetermined range of the player character PC that keeps the ball object B is The correction is made according to the posture vector Vc of the player character PC. Specifically, since the vector obtained by projecting the posture vector Vc onto the virtual horizontal plane is corrected by adding it to the movement vector of the player character of the opponent team, the moving direction of the player character is the vertical direction of the virtual game space. The posture vector Vc changes in the direction in which it tilts. That is, the player character of the opponent team moves according to the posture of the player character PC changed by the action of the player moving the entire subunit 76, and the opponent player is drawn to the faint that is dribbling in a so-called soccer game. Behavior is expressed.

  Returning to FIG. 19, after the processing of step 48, the CPU 30 determines whether any player character belonging to the team X holds the ball object B (step 49). Then, when any player character belonging to the team X holds the ball object B (that is, when the team X is the attacking side), the CPU 30 proceeds to the next step 50. On the other hand, when the player character belonging to the team X does not hold the ball object B, the CPU 30 proceeds to the next step 19.

  In step 50, the CPU 30 may set the magnitude (absolute value) of acceleration in the X-axis direction indicated by the latest sub-acceleration data referred to in step 47 to a predetermined acceleration A1 or more (for example, 0.5 G or more. Whether or not the value is acceptable). If the magnitude of the acceleration in the X-axis direction is equal to or greater than the predetermined acceleration A1, the CPU 30 advances the process to the next step 51. On the other hand, when the magnitude of the acceleration in the X-axis direction is less than the predetermined acceleration A1, the CPU 30 ends the process by the subroutine and proceeds to the process of step 16 above.

  In step 51, the CPU 30 refers to the history of the sub acceleration data included in the operation information transmitted from the operation mode Da from the player mode subunit of the team X, and determines the acceleration in the X-axis direction indicated by the history of the sub acceleration data. It is determined whether or not the direction has been reversed n times (n is an integer equal to or greater than 1) with a magnitude greater than or equal to the predetermined acceleration A1 within the most recent predetermined time. For example, referring to the history of the sub-acceleration data, “the acceleration of the latest sub-acceleration data (data determined to be greater than or equal to the acceleration A1 in step 50) within the most recent past predetermined time is opposite in polarity and absolute. It is determined whether or not there is data having a value greater than or equal to acceleration A1 (when n = 1). Or, “in the most recent past predetermined time, there is data that is opposite in sign to the acceleration indicated by the latest sub acceleration data and whose absolute value is greater than or equal to the acceleration A1, and before that data, It is determined whether or not there is data in which the sign is opposite and the absolute value is greater than or equal to the acceleration A1 (when n = 2). Alternatively, it may be determined whether or not the direction of the acceleration in the X-axis direction indicated by the history of the sub acceleration data is reversed n times with a magnitude equal to or greater than the predetermined acceleration A1, and the inversion interval is within a predetermined time. Good.

  Then, when the acceleration direction in the X-axis direction is reversed within a predetermined time, the CPU 30 adds a vector having a predetermined magnitude in the Xp-axis direction (the magnitude of the vector is the movement vector Vmpc of the player character PC in the team X). The direction of the vector may be the positive direction of the Xp axis if the acceleration in the X axis direction is positive, and X If the acceleration in the axial direction is negative, the negative direction of the Xp axis) is added to obtain a movement vector Vmpc. (Step 52), the process by the subroutine is finished, and the process proceeds to the process of Step 16. By the processing of step 50 to step 52, the moving speed of the player character PC operated by the player in the virtual game space is moved zigzag by swinging the subunit 76 left and right (that is, in the X-axis direction). The movement is controlled. On the other hand, if the direction of acceleration in the X-axis direction is not reversed within a predetermined time, the CPU 30 ends the process by the subroutine as it is and proceeds to the process of step 16.

  The subunit movement process described above may be performed as follows. As a first example, when the magnitude (absolute value) of the acceleration in the X-axis direction indicated by the latest sub-acceleration data is within a predetermined value (for example, gravitational acceleration (1.0 G)), in step 48, the latest sub-acceleration data is displayed. The posture vector is controlled using the acceleration in the X-axis direction indicated by the acceleration data. As a second example, when the magnitude (absolute value) of acceleration in the X-axis direction indicated by the latest sub-acceleration data is larger than the predetermined value, in step 48, the player character PC moves the upper body or the whole body in the Xp-axis direction. Perform motion control that makes a large swing motion (like a posture that expresses a feint).

  Further, the first example of the subunit movement process may be as follows. As a third example, the magnitude (absolute value) of acceleration in the X-axis direction indicated by the latest sub-acceleration data is within the predetermined value, and the direction of acceleration in the X-axis direction indicated by the history of the sub-acceleration data is closest. In the predetermined time, when the acceleration is reversed n times (n is an integer of 1 or more) with a magnitude greater than or equal to the acceleration A1, a vector having a predetermined magnitude in the Xp axis direction is added to the movement vector Vmpc of the player character PC. , A movement vector Vmpc. As a fourth example, when the magnitude (absolute value) of the acceleration in the X-axis direction indicated by the latest sub-acceleration data is within the predetermined value A2 and other than the third example, in step 48, the latest sub-acceleration data is updated. The posture vector is controlled using the acceleration in the X-axis direction indicated by the acceleration data. In the case of the first example and the fourth example described above, the “player character of the opponent team arranged in the predetermined range of the player character PC” described in step 14 and step 25 is used as the feint of the player character PC. The movement control to be performed may not be performed.

  As described above, in the subunit movement process in step 15, the movement direction (and additionally the movement speed) of the player character PC is controlled by the direction instruction section (stick 78 a) provided in the subunit 76. The posture of the player character PC is controlled according to the acceleration data output from the acceleration sensor 761 provided in the subunit 76. That is, the player can input the moving direction control and the posture control of the player character PC efficiently and intuitively with one hand.

  In the subunit moving process, the moving direction (and additionally the moving speed) of the player character PC is controlled by the direction indicating unit (stick 78a) provided in the subunit 76, and the moving direction is changed. The correction is made according to the acceleration data output from the acceleration sensor 761 provided in the subunit 76. That is, the player can input the movement direction control of the player character PC and the correction thereof with one hand efficiently and intuitively. Specifically, the following can be performed. The direction of the movement vector of the player character PC is determined according to the tilt direction of the stick 78a. That is, for example, when an upward direction is designated, the player character PC moves in the positive Z-axis direction (forward direction of the player character PC) of the local coordinate system of the player character PC (moves in the direction of the forward direction vector of the player character PC). When the direction indicating means is instructed downward, it moves in the negative Z-axis direction of the local coordinate system of the player character PC. When the direction indicating unit is instructed to the right, the X direction positive direction of the local coordinate system is moved. Then, when the direction indicating means is instructed in the left direction, movement control is performed so as to move in the X axis negative direction of the local coordinate system. The magnitude of the movement vector may be a fixed value or may be determined according to the tilt amount of the stick 78a. Then, according to the output of the acceleration sensor 761, the moving direction of the player character PC can be corrected as follows.

  As a first example of correcting the moving direction of the player character PC, the X axis, the Y axis, and the Z axis of the acceleration sensor 761 are associated with the X axis, the Y axis, and the Z axis of a predetermined coordinate system (or advance), respectively. The output vector of the acceleration sensor 761 is converted into a direction vector of the virtual game space (corresponding to a direction and two directions orthogonal to the direction). Then, using the direction vector as a correction vector, the correction vector is added to the movement vector obtained by tilting the stick 78a. The magnitude of the correction vector may be a fixed value or may be determined according to the magnitude of the output vector.

  As a second example of correcting the moving direction of the player character PC, when the output value of the acceleration sensor 761 in a predetermined direction (for example, the X-axis direction) is a predetermined value or more, the corresponding direction (for example, X The correction vector in the axial direction is added to the movement vector obtained by tilting the stick 78a.

  As a third example of correcting the moving direction of the player character PC, the magnitude corresponding to the output value of the acceleration sensor 761 in a predetermined direction (for example, the X-axis direction) and a corresponding direction (for example, the X-axis) of the predetermined coordinate system (Direction) correction vector is added to the movement vector obtained by tilting the stick 78a.

  Note that the second and third examples of correcting the moving direction of the player character PC may be performed in a plurality of directions. That is, for example, in the third example, the correction vector in the X-axis direction of the predetermined coordinate system having a magnitude corresponding to the output value in the X-axis direction of the acceleration sensor 761 is used as the movement vector obtained by tilting the stick 78a. In addition, a correction vector in the Y-axis direction of a predetermined coordinate system may be added with a magnitude corresponding to the output value of the acceleration sensor 761 in the Y-axis direction.

  The predetermined coordinate system may be a local coordinate system of the player character PC or a virtual game space coordinate system (in this case, the direction vector is typically a virtual vertical direction, a virtual horizontal direction, or the like). ), A camera coordinate system, a coordinate system obtained by projecting the camera coordinate system onto a virtual horizontal plane, or a coordinate system based on the moving direction determined by the direction indicating unit (for example, the correction vector is Or a direction orthogonal to the moving direction).

  In the subunit moving process, the moving speed of the player character PC is controlled while the moving direction of the player character PC is controlled by the direction indicating unit (stick 78a) provided in the subunit 76. That is, the player can input the movement direction control and the movement speed control of the player character PC efficiently and intuitively with one hand. In this case, it can be as follows. The moving direction of the player character PC is determined according to the tilt direction of the stick 78a. The moving speed (absolute value) of the player character PC can be determined as follows according to the output of the acceleration sensor 761.

  A first example of determining the moving speed of the player character PC is that the moving speed is set to a predetermined speed when the absolute value of the output vector of the acceleration sensor 761 is equal to or larger than a predetermined value, and the moving speed is lower than the predetermined value. Is set to 0.

  In a second example of determining the moving speed of the player character PC, the moving speed is set to a speed corresponding to the absolute value of the output vector of the acceleration sensor 761 (the higher the absolute value is, the higher the moving speed is. To do). At this time, when a predetermined component (for example, a Z-axis direction component) of the output vector is positive, the player character PC moves in a moving direction corresponding to the tilt direction of the stick 78a, and when negative, the player character PC moves to the stick 78a. You may make it move to the direction opposite to the moving direction according to the inclination direction. Further, the moving speed may be determined according to the second example only when the output component in the predetermined direction is positive.

  A third example of determining the moving speed of the player character PC is to set the moving speed to a predetermined speed when an output component (for example, an output value in the Z-axis direction) of the acceleration sensor 761 is a predetermined value or more. When it is smaller than the predetermined value, the moving speed is set to zero.

  In a fourth example of determining the moving speed of the player character PC, the moving speed is set to a speed corresponding to the absolute value of the output component in the predetermined direction of the acceleration sensor 761 (for example, the output value in the Z-axis direction).

  In the third and fourth examples for determining the moving speed of the player character PC, when the output component in the predetermined direction is positive, the player character PC moves in the moving direction according to the tilting direction of the stick 78a, and the predetermined character is output. When the direction output component is negative, the player character PC may move in the direction opposite to the moving direction. Further, the moving speed may be determined by the third and fourth examples only when the output component in the predetermined direction is positive.

  A fifth example of determining the moving speed of the player character PC is an output component of the acceleration sensor 761 in a direction corresponding to the tilt direction of the stick 78a (for example, output in the Z-axis direction when the tilt direction of the stick 78a is upward). When the tilting direction of the stick 78a is rightward, the movement speed is set to a predetermined speed when the output value in the X-axis direction is equal to or greater than a predetermined value, and when it is smaller than the predetermined value, the movement speed is set to zero. .

  In the sixth example of determining the moving speed of the player character PC, the moving speed is output in the direction corresponding to the tilt direction of the stick 78a of the acceleration sensor 761 (for example, Z when the tilt direction of the stick 78a is upward). The speed is determined according to the absolute value of the output value in the axial direction and the output value in the X-axis direction when the tilt direction of the stick 78a is rightward.

  In the fifth and sixth examples for determining the moving speed of the player character PC, when the output component in the corresponding direction is positive, the player character PC moves in the moving direction corresponding to the tilting direction of the stick 78a. When the output component in the corresponding direction is negative, the player character PC may move in the direction opposite to the moving direction.

  In the subunit movement process, the movement speed correction control is performed while the movement direction and movement speed of the player character PC are controlled by the direction instruction section (stick 78a) provided in the subunit 76. That is, the player can input the movement direction control of the player character PC and the movement speed correction control efficiently and intuitively with one hand. In this case, it can be as follows. The moving direction of the player character PC is determined according to the tilt direction of the stick 78a, and the moving speed of the player character PC is determined according to the tilt amount of the stick 78a. In accordance with the output of the acceleration sensor 761, the moving speed of the player character PC can be corrected as follows.

  A first example of correcting the moving speed of the player character PC is that when the absolute value of the output vector of the acceleration sensor 761 is greater than or equal to a predetermined value, the moving speed corresponding to the tilt amount of the stick 78a is used as the moving speed of the player character PC. If it is used as it is and is smaller than the predetermined value, the moving speed of the player character PC is corrected to zero.

  A second example of correcting the moving speed of the player character PC is that when the absolute value of the output vector of the acceleration sensor 761 is a predetermined value or less, the moving speed corresponding to the tilt amount of the stick 78a is used as the moving speed of the player character PC. If it is used as it is and is larger than the predetermined value, the moving speed of the player character PC is increased and corrected (added predetermined value, n times (n> 1), etc.).

  In the third example of correcting the moving speed of the player character PC, the moving speed corresponding to the tilt amount of the stick 78a is increased and corrected to the moving speed of the player character PC according to the absolute value of the output vector of the acceleration sensor 761 ( The larger the absolute value, the larger the increase amount).

  In the second and third examples in which the moving speed of the player character PC is corrected, when a predetermined component (for example, a Z-axis direction component) of the output vector is positive, the player moves in the moving direction according to the tilt direction of the stick 78a. When the character PC moves and is negative, the player character PC may move in a direction opposite to the moving direction corresponding to the tilt direction of the stick 78a. Further, the moving speed may be corrected by the second and third examples only when the output component in the predetermined direction is positive.

  A fourth example of correcting the moving speed of the player character PC is a movement according to the tilt amount of the stick 78a when an output component (for example, an output value in the Z-axis direction) of the acceleration sensor 761 is a predetermined value or more. The speed is used as it is as the moving speed of the player character PC, and when it is smaller than the predetermined value, the moving speed of the player character PC is corrected to zero.

  A fifth example of correcting the moving speed of the player character PC is a movement according to the tilt amount of the stick 78a when the output component (for example, the output value in the Z-axis direction) of the acceleration sensor 761 is not more than a predetermined value. The speed is used as it is as the moving speed of the player character PC, and when it is larger than the predetermined value, the moving speed of the player character PC is corrected to be increased. The moving speed may be corrected by the fifth example only when the output component in the predetermined direction is positive. When the output component in the predetermined direction is negative, the movement according to the tilt amount of the stick 78a. The moving speed of the player character PC may be corrected to decrease using the speed.

  A sixth example for correcting the movement speed of the player character PC is a movement according to the amount of tilt of the stick 78a according to the magnitude of the output component (for example, the output value in the Z-axis direction) of the acceleration sensor 761 in a predetermined direction. The movement speed of the player character PC is corrected using the speed (the larger the absolute value is, the larger the increase amount is). Note that the moving speed may be corrected by the sixth example only when the output component in the predetermined direction is positive, and when the output component in the predetermined direction is negative, the movement according to the tilt amount of the stick 78a. The moving speed of the player character PC may be corrected to decrease using the speed.

  A seventh example of correcting the moving speed of the player character PC is an output component of the acceleration sensor 761 in a direction corresponding to the tilting direction of the stick 78a (for example, when the tilting direction of the stick 78a is upward, When the output value, the output value in the positive direction of the X-axis when the tilt direction of the stick 78a is rightward, etc.), the moving speed according to the tilt amount of the stick 78a is used as the moving speed of the player character PC as it is. If it is smaller than the predetermined value, the moving speed of the player character PC is corrected to zero.

  An eighth example of correcting the moving speed of the player character PC is a moving speed corresponding to the tilt amount of the stick 78a when the output component of the acceleration sensor 761 in the direction corresponding to the tilt direction of the stick 78a is equal to or less than a predetermined value. Is used as it is as the moving speed of the player character PC, and when it is larger than the predetermined value, the moving speed of the player character PC is increased and corrected.

  In the ninth example of correcting the moving speed of the player character PC, the moving speed corresponding to the tilt amount of the stick 78a is set according to the magnitude of the output component of the acceleration sensor 761 in the direction corresponding to the tilting direction of the stick 78a. And the movement speed of the player character PC is corrected to increase (the larger the absolute value, the larger the increase amount).

  In the eighth and ninth examples for correcting the moving speed of the player character PC, the moving speed may be corrected by the eighth and ninth examples only when the output component in the predetermined direction is positive. When the corresponding output value is positive, the player character PC moves in the moving direction corresponding to the tilt direction of the stick 78a, and when the corresponding output value is negative (when there is an output in the direction opposite to the corresponding direction). ), The player character PC may move in a direction opposite to the moving direction.

  In the subunit moving process, the direction of the player character PC (and additionally the moving speed) is controlled by the direction indicating section (stick 78a) provided in the subunit 76, while the player character PC Operation control (for example, the above-described faint operation) is performed. That is, the player can input the moving direction control and the motion control of the player character PC efficiently and intuitively with one hand. This is realized by controlling the player character PC to perform a predetermined action when the output of the acceleration sensor 761 satisfies a predetermined condition. Furthermore, in the case where at least one of the above-described subunit movement processes and a process of controlling the player character PC to perform a predetermined action when the output of the acceleration sensor 761 satisfies a predetermined condition are performed simultaneously. Is a process of performing at least one of the examples of the subunit movement process described above when the magnitude of the output value of the acceleration sensor 761 is less than or equal to a predetermined value, and controlling to perform a predetermined operation when it is greater than the predetermined value May be implemented.

  Further, in the subunit movement process, the position of the player character PC determined in accordance with the operation of the direction indicating section (stick 78a) provided in the subunit 76 may be determined in a different manner. FIG. 30 is a subroutine showing the detailed operation of another example in the subunit movement process. Other examples of the subunit movement process shown in FIG. 30 are the processes performed between step 43 and step 44, the process of step 46, and the step 52, compared to the subunit movement process shown in FIG. The processing of is different. Hereinafter, processing different from the subunit movement processing illustrated in FIG. 19 will be described, and detailed description of processing similar to the subunit movement processing illustrated in FIG. 19 will be omitted. In another example of the subunit movement process, position data indicating the position of the player character PC in the virtual game space is stored in an area (not shown) of the main memory 33 (hereinafter referred to as PC position data).

  In FIG. 30, the CPU 30 updates the PC position data in the main memory 33 based on the calculated movement vector Vmpc calculated in step 43 based on the direction instruction input (step 171), and the process proceeds to step 44. To proceed. For example, in the process of step 171, the position obtained by moving the position in the virtual game space indicated by the immediately preceding PC position data stored in the main memory 33 using the movement vector Vmpc is calculated, and the calculated position is calculated. Update to the indicated PC position data.

  On the other hand, if the acceleration in the positive direction of the Z-axis is equal to or greater than a predetermined value in step 45, the CPU 30 calculates a displacement vector according to the acceleration data Da4 (step 172), and proceeds to step 47. Here, the method for calculating the displacement vector in step 172 is the same as the method for calculating the correction vector described above for step 46 (including the variations described above).

  If the acceleration direction in the X-axis direction is reversed within the predetermined time in step 51, the CPU 30 calculates a displacement vector according to the acceleration data Da4 (step 173) and ends the processing by the subroutine. . Here, the method for calculating the displacement vector in step 173 is the same as the method for calculating the correction vector described above for step 52 (including the variations described above).

  In the process of step 21 shown in FIG. 18, a sum vector obtained by adding the displacement vector calculated in step 172 and the displacement vector calculated in step 173 is calculated, and the virtual game space indicated by the PC position data is obtained. The player character PC is moved in the virtual game space to the position displaced by the sum vector, and the game image is displayed on the monitor 2. However, in step 21, the PC position data stored in the main memory 33 is not updated. If such processing is performed, the basic position (position indicated by the PC position data) of the player character PC in the virtual game space is moved by the direction instruction input. Then, in accordance with the acceleration data output from the acceleration sensor 701, the player character PC is moved and displayed at a position where the basic position is temporarily displaced. By such processing, operability without a sense of incongruity can be obtained.

  Next, with reference to FIG. 20, the detailed operation of the pass process in step 16 will be described.

  In FIG. 20, the CPU 30 refers to the latest core key data included in the operation information transmitted from the player mode core unit of the team X from the operation information Da (step 81). Next, the CPU 30 determines whether or not the player is pressing only the operation unit 72d (A button) of the core unit 70 based on the core key data referred to in step 81 (step 82). Then, when the player presses only the A button, the CPU 30 proceeds to the next step 83. On the other hand, if the player does not press the A button or presses another button (for example, the B button) at the same time as the A button, the CPU 30 ends the process by the subroutine and performs the process of step 17 above. Proceed to

  In step 83, the CPU 30 refers to the latest first coordinate data Da1 and second coordinate data Da2 included in the operation information transmitted from the player mode core unit of the team X from the operation information Da (step 83). Next, the CPU 30 calculates the instruction coordinates corresponding to the first coordinate data Da1 and the second coordinate data Da2 referred to in step 83 and the position of the virtual game space corresponding to the instruction coordinates, and each of the team X's. The instruction coordinate data De and the virtual space position coordinate data Df corresponding to the player mode core unit are updated (step 84), and the process proceeds to the next step. Hereinafter, an example of calculating the designated coordinates and the virtual space position using the coordinate data will be described in detail.

  First, the CPU 30 calculates direction data from the first coordinate data Da1 to the second coordinate data Da2. Specifically, the CPU 30 refers to the first coordinate data Da1 and the second coordinate data Da2, and calculates a vector having the position of the first coordinate data Da1 as the start point and the position of the second coordinate data Da2 as the end point. Then, the CPU 30 stores the calculated vector data in the main memory 33 as direction data. The rotation of the main body of the core unit 70 about the direction perpendicular to the imaging surface of the core unit 70 can be calculated based on the difference between the direction data and a predetermined reference direction.

  Further, the CPU 30 calculates midpoint data indicating the midpoint between the first coordinate data Da1 and the second coordinate data Da2. Specifically, the CPU 30 refers to the first coordinate data Da1 and the second coordinate data Da2, and calculates the coordinates of the midpoint. Then, the CPU 30 stores the calculated coordinate data of the midpoint in the main memory 33. Here, the midpoint data indicates the position of the target image (markers 8L and 8R) in the captured image. The change in the image position due to the change in the position of the core unit 70 can be calculated from the difference between the midpoint data and the predetermined reference position.

  Here, the positional relationship among the markers 8L and 8R, the display screen of the monitor 2, and the core unit 70 will be considered. For example, when two markers 8L and 8R are installed on the upper surface of the monitor 2 (see FIG. 1), and the player points to the center of the display screen of the monitor 2 using the core unit 70 with the upper surface facing upward (imaging) A state in which the center of the display screen is imaged in the center of the captured image of the information calculation unit 74 is considered. At this time, in the captured image of the imaging information calculation unit 74, the position of the middle point (middle point of the markers 8L and 8R) of the target image does not match the position (center of the display screen). Specifically, the position of the target image in the captured image is a position above the center of the captured image. When the target image is located at such a position, a reference position is set such that the center of the display screen is pointed. On the other hand, since the position of the target image in the captured image also moves in accordance with the movement of the core unit 70 (the movement direction is the reverse direction), the display screen corresponds to the movement of the position of the target image in the captured image. By performing the process of moving the position pointing to the display unit, the display screen reference position (position coordinate in the screen coordinate system) pointed to by the core unit 70 can be calculated. Here, for setting the reference position, the player may point in advance to a predetermined position on the display screen, and the position of the target image at that time may be stored in association with the predetermined position. If the positional relationship with the screen is fixed, it may be set in advance. Further, when the markers 8L and 8R are provided separately from the monitor 2 and are placed and used near the monitor 2 (eg, above or below the monitor 2), before the game starts Then, the player inputs the position where the markers 8L and 8R are placed with respect to the monitor (for example, selected from options such as placed on or below the monitor 2), and the optical disc. 4 and the built-in non-volatile memory of the game apparatus 3 store reference position data when placed on the monitor 2 and reference position data when placed under the monitor 2, respectively. You may select and use. Such position coordinates in the screen coordinate system are calculated by linear conversion using a function for calculating the display screen reference coordinates (indicated coordinates) of the monitor 2 from the midpoint data. This function is a coordinate representing a position on the display screen (position coordinate in the screen coordinate system) indicated by the core unit 70 when the captured image is captured, using a midpoint coordinate value calculated from a captured image. It is to convert to. With this function, the designated coordinates based on the display screen can be calculated from the midpoint coordinates.

  However, when the player points to the center of the display screen of the monitor 2 using the core unit 70 whose upper surface is not in the upward direction (for example, the right direction), the position of the target image in the captured image is from the center of the captured image. The position is shifted in a direction other than upward (for example, to the left). That is, due to the inclination of the core unit 70, the moving direction of the core unit 70 does not match the moving direction of the display screen reference position. Therefore, the midpoint data is corrected based on the direction data. Specifically, the midpoint data is corrected to the midpoint coordinates when the upper surface of the core unit 70 is in the upward direction. More specifically, when setting the reference position, the direction data reference is also set, and the midpoint data is set in an amount corresponding to the angle difference between the direction data and the reference direction, with the center of the captured image as the axis. The coordinates indicated by the midpoint data are rotated and corrected. Then, the indicated coordinates are calculated as described above using the corrected midpoint data.

  In addition, when the calculated designated coordinates in the screen coordinate system are converted into virtual space coordinates representing a position in the virtual game space (virtual space position), the designated coordinate in the virtual game space corresponds to the position in the screen coordinate system. What is necessary is just to convert. Here, the position in the virtual game space corresponding to the position in the screen coordinate system is a position in the virtual game space displayed at a position on the display screen of the monitor 2 (for example, a position projected through) or screen coordinates. The three-dimensional coordinate values of the virtual game space that are directly specified from the position coordinates of the system.

  The essential principle of the calculation process of the indicated coordinates is that the displacement of the indicated two-dimensional coordinates from a predetermined reference position is calculated and the coordinates are set by the change of the position of the target image due to the movement of the core unit 70. That's it. Therefore, the position coordinates in the screen coordinate system can be widely used as input for other two-dimensional coordinates. For example, the position coordinates of the screen coordinate system can be directly used as the values of the x and y coordinates in the world coordinate system. In this case, a calculation process for associating the movement of the target image with the movement of the x coordinate and the y coordinate from the reference position in the world coordinate system may be performed regardless of the display screen of the monitor 2. Further, when a two-dimensional game image is displayed on the monitor 2, the position coordinates of the screen coordinate system can be directly used as the values of the x coordinate and the y coordinate in the two-dimensional game coordinate system.

  After the process of step 84, the CPU 30 determines whether or not the virtual space position of the virtual game space corresponding to the calculated designated coordinates is a position on the virtual field (step 85). For example, the virtual field is a virtual plane indicating the ground of the game space including the virtual soccer field. Next, when the virtual space position is on the virtual field, the CPU 30 proceeds to the next step 90. On the other hand, if the virtual space position is not on the virtual field, the CPU 30 determines whether or not the indicated coordinates of the screen coordinate system are out of or above the display area of the monitor 2 (step 86) and the indication of the screen coordinate system. It is determined whether the coordinates are out of the left or right of the display area of the monitor 2 (step 87). Then, the CPU 30 advances the processing to the next step 88 when the designated coordinates are out of the display area of the monitor 2 (Yes in step 86). Further, when the designated coordinates are out of the left and right of the display area of the monitor 2 (Yes in Step 87), the CPU 30 advances the process to the next Step 89. On the other hand, when the designated coordinates are out of the display area of the monitor 2 except for the top and bottom and the left and right, or the designated coordinates are invalid (for example, cannot be calculated) (No in Step 86 and Step 87), the CPU 30 proceeds to the next step. The process proceeds to 95.

  In step 88, the CPU 30 sets a ball movement vector indicating the movement direction and movement speed of the ball object B to a predetermined size in a direction parallel to the goal line of the soccer field set in the virtual game space. The data Dc is updated, and the process proceeds to the next step 95. Note that the direction of the ball movement vector set in step 88 may be set to a direction in which the line-of-sight direction vector of the virtual camera is projected onto the virtual horizontal plane of the virtual game space.

  In step 89, the CPU 30 sets a ball movement vector indicating the movement direction and movement speed of the ball object B with a predetermined size in a direction parallel to the touch line of the soccer field set in the virtual game space. The data Dc is updated, and the process proceeds to the next step 95. Note that the direction of the ball movement vector set in step 89 may be set in a horizontal direction perpendicular to the direction in which the line-of-sight direction vector of the virtual camera is projected onto the virtual horizontal plane of the virtual game space.

  In step 90, the CPU 30 determines that the area within the area A centered on the virtual space position calculated in step 84 (typically, within the circular area having a predetermined radius R1 centered on the virtual space position, It is determined whether or not the player character of team X is placed in the area), and if the determination is Yes, the selected character is selected (if a plurality of player characters are applicable) , The player character closest to the virtual space position is selected). Further, when the player character of team X is not arranged in the area A, the CPU 30 is in the area B centered on the virtual space position calculated in step 84 (typically, the virtual space position is the center). If the player character of the team X is placed in a circle area of the predetermined radius R2 (> R1), but may not be a circle area), and the determination is Yes Selects the selected character (step 92) (when a plurality of player characters are applicable, the player character closest to the virtual space position may be selected, or all or a plurality of the plurality of player characters may be selected. May be selected). Then, when the player character of team X is arranged in the area A (Yes in step 90), the CPU 30 proceeds to the next step 91. Further, when the player character of team X is arranged in the area B (Yes in step 92), the CPU 30 advances the process to the next step 93. Further, the CPU 30 advances the process to the next step 94 when the player character of the team X is not arranged in any of the area A and the area B (No in step 90 and step 92). For example, as shown in FIG. 27, the region A and the region B are each formed as a circular region centered on the virtual space position TP, and the region B is larger than the region A. And CPU30 judges the player character arrange | positioned in the area | region A and the area | region B with reference to the newest position data Dh based on the arrangement position of each player character in virtual game space.

  In step 91, the CPU 30 sets a ball movement vector according to the arrangement position of the player character selected in step 90, and updates the movement vector data Dc. For example, the CPU 30 sets the direction from the current position of the ball object B to the arrangement position of the player character as the direction of the ball movement vector. Further, a size corresponding to a virtual distance from the current position of the ball object B to the arrangement position of the player character may be set as the size of the ball movement vector. Then, the CPU 30 advances the process to the next step 95.

  In step 93, the CPU 30 sets the movement vector of the player character selected in step 92 according to the virtual space position TP, and updates the movement vector data Dc. For example, the CPU 30 sets the direction from the current arrangement position of the player character selected in step 92 to the virtual space position TP as the direction of the movement vector of the player character. Furthermore, you may set the magnitude | size according to the virtual distance from the said present arrangement position to virtual space position TP as a magnitude | size of the movement vector of the said player character. The CPU 30 then proceeds to the next step 94.

  In step 94, the CPU 30 sets a ball movement vector according to the virtual space position TP, and updates the movement vector data Dc. For example, the CPU 30 sets the direction from the current position of the ball object B to the virtual space position TP as the direction of the ball movement vector. Further, a size corresponding to a virtual distance from the current position of the ball object B to the virtual space position TP may be set as the size of the ball movement vector. Then, the CPU 30 advances the process to the next step 95.

  As described above, the movement vector of the ball object B is set by the processing of the above steps 90 to 94 performed when the player presses the A button, and the movement direction (and additionally the movement of the ball object B) is set. Speed) is determined, the direction in which the ball passes in a so-called soccer game is set. Here, as apparent from the above, when the player of the own team does not exist near the virtual space position TP indicated by the core unit 70, the target point to which the ball object B is passed becomes the virtual space position TP. Further, when the player of the own team exists in the area A near the virtual space position TP indicated by the core unit 70, the target point to which the ball object B is passed is the player of the own team existing in the area A. It becomes. Furthermore, when the player of the own team exists in the area B slightly apart from the virtual space position TP indicated by the core unit 70, the target point to which the ball object B is passed becomes the virtual space position TP, The player of the own team that is present also moves to the virtual space position TP.

  In step 95, the CPU 30 refers to the latest sub acceleration data included in the operation information transmitted from the player mode subunit of the team X from the operation information Da. Then, the CPU 30 determines whether or not the acceleration in the Z-axis direction indicated by the sub acceleration data is negative (that is, the acceleration in the negative Z-axis direction is detected) (step 96). Then, when the acceleration in the Z-axis direction is negative, the CPU 30 adds the vertical upward vector to the ball movement vector (step 97). The vector to be added may be a magnitude corresponding to the magnitude (absolute value) of acceleration in the Z-axis direction. Then, the process according to the subroutine is terminated, and the process proceeds to step 17. By the process of step 97, the trajectory of the ball object B passed by the player character PC performs an action such that the player lifts the front of the subunit 76 (that is, acceleration in the negative direction of the Z axis occurs), thereby It becomes a trajectory to kick high in the game space. On the other hand, if the acceleration in the Z-axis direction is not negative, the CPU 30 ends the process of the subroutine as it is and proceeds to the process of step 17.

  As described above, in the pass process in step 16, when the player presses only the A button, the ball object B moves from the position of the player character PC that keeps the ball object B. Then, coordinate data (first coordinates) obtained from the core unit 70 while the moving direction (and additionally the moving speed) of the player character PC is controlled by the direction indicating unit (stick 78a) provided in the subunit 76. The movement direction (and additionally the movement speed) of the ball object B is controlled by the data Da1 and the second coordinate data Da2. Therefore, the player can operate different characters (objects) while operating the two units. That is, the player moves from the movement direction control of the first character (player character PC) and the position of the first character (more precisely, the position of the second character determined accompanying the position of the first character). The moving direction control of the second character (ball object B) can be input efficiently and intuitively independently. Further, the operation for moving the player character PC and the operation for determining the pass direction are independent (in addition, the housing 77 for the operation for moving the player character PC and the housing 71 for the operation for determining the pass direction are provided. Therefore, it is possible to realize a real soccer game with a high degree of freedom.

  Further, regarding the movement control of the second character (ball object B), the second direction vector determined in accordance with the output of the acceleration sensor 761 of the subunit 76 is used as the first direction vector determined by the designated coordinates by the core unit 70. To obtain the moving direction vector of the second character. Specifically, it can be as follows.

  As a first example of calculating the moving direction vector of the second character, the X axis, Y axis, and Z axis of the acceleration sensor 761 are respectively associated with the X axis, Y axis, and Z axis of a predetermined coordinate system (or advanced) The output vector of the acceleration sensor 761 is converted into a direction vector of the virtual game space (corresponding to a direction and two directions orthogonal to the direction). Then, the direction vector is set as the second direction vector, and the second direction vector is added to the first direction vector. The magnitude of the second direction vector may be a fixed value or may be determined according to the magnitude of the output vector.

  As a second example of calculating the moving direction vector of the second character, when the output value of the acceleration sensor 761 in a predetermined direction (for example, the X-axis direction) is equal to or greater than a predetermined value, the corresponding direction (for example, the predetermined coordinate system) The second direction vector in the (X-axis direction) is added to the first direction vector.

  As a third example of calculating the movement direction vector of the second character, the magnitude corresponds to the output value of the acceleration sensor 761 in a predetermined direction (for example, the X-axis direction) and the corresponding direction (for example, X The second direction vector in the axial direction is added to the first direction vector.

  Note that the second and third examples of calculating the moving direction vector of the second character may be implemented in a plurality of directions. That is, for example, for the third example, the second direction vector in the X-axis direction of the predetermined coordinate system is added to the first direction vector with a magnitude corresponding to the output value of the acceleration sensor 761 in the X-axis direction. You may add the 2nd direction vector of the Y-axis direction of a predetermined coordinate system with the magnitude | size according to the output value of the Y-axis direction of the acceleration sensor 761 to the said 1st direction vector.

  The predetermined coordinate system may be a local coordinate system of the player character PC or a coordinate system of a virtual game space (in this case, the second direction vector is typically a virtual vertical direction, a virtual horizontal direction, etc. It may be a camera coordinate system, a coordinate system obtained by projecting the camera coordinate system onto a virtual horizontal plane, or a coordinate system based on the moving direction determined by the direction indicating unit (for example, the first The two-direction vector may be a direction orthogonal to the moving direction).

  As a result, it is possible to realize an operation of correcting the direction by tilting or moving the subunit while controlling the moving direction of the character by the designated coordinates by the core unit 70.

  Next, with reference to FIG. 21, detailed operation | movement is demonstrated about the 1st chute | shoot process in the said step 17. FIG.

  In FIG. 21, the CPU 30 refers to the latest core key data included in the operation information transmitted from the player mode core unit of the team X from the operation information Da (step 101). Next, the CPU 30 determines whether or not the player is simultaneously pressing the operation unit 72d (A button) and the operation unit 72i (B button) of the core unit 70 based on the core key data referred to in step 101 above. (Step 102). Then, the CPU 30 advances the process to the next step 103 when the player presses the A and B buttons simultaneously. On the other hand, if the player does not press the A and B buttons at the same time, the CPU 30 ends the process by the subroutine and proceeds to the process of step 18.

  In step 103, the CPU 30 refers to the latest core acceleration data included in the operation information transmitted from the player mode core unit of the team X from the operation information Da. Then, the CPU 30 calculates a ball movement vector according to the core acceleration data, updates the movement vector data Dc (step 104), and advances the processing to the next step. For example, the CPU 30 determines the acceleration in the Z-axis direction included in the referenced core acceleration data in the forward direction (for example, the movement direction; that is, the direction of the PC movement direction vector) of the player character PC keeping the ball object B. A ball movement vector having a size corresponding to the size of is calculated.

As a result, the moving speed of the ball object B is output from the acceleration sensor 701 provided in the core unit 70 while the moving direction of the ball object B is controlled by the direction indicating unit (stick 78a) provided in the subunit 76. It is determined according to the acceleration data. That is, the player can input the movement direction control and the movement speed control of the ball object B independently and efficiently with each hand. Further, the moving speed of the ball object B is controlled according to the amount of inclination of the direction indicating portion (stick 78 a) provided in the subunit 76, so that the moving speed of the ball object B is accelerated by the acceleration provided in the subunit 76. Correction may be made in accordance with acceleration data output from the sensor 761 (or a component of the acceleration data in a predetermined axis direction) (for example, when there is acceleration in the Z-axis direction, a predetermined value is added. Alternatively, it may be multiplied by n (n> 1), or a multiple may be determined according to the magnitude of acceleration in the Z-axis direction). That is, the player can input the moving direction control and the moving speed control (or moving speed correction control) of the ball object B independently and efficiently with each hand.

  Next, the CPU 30 refers to the latest sub acceleration data included in the operation information transmitted from the player mode subunit of the team X from the operation information Da (step 105). Then, the CPU 30 determines whether or not the acceleration in the Z-axis direction indicated by the sub acceleration data is negative (that is, the acceleration in the negative Z-axis direction is detected) (step 106). When the acceleration in the Z-axis direction is negative, the CPU 30 adds the vector in the vertical direction with respect to the virtual game space to the ball movement vector and updates the movement vector data Dc (step 107). Proceed with the process. Note that the vertical vertical vector to be added may have a magnitude corresponding to the magnitude of the acceleration in the Z-axis direction. On the other hand, if the acceleration in the Z-axis direction is not negative, the CPU 30 proceeds to the next step 108 as it is.

  In step 108, the CPU 30 changes the ball movement vector according to the acceleration data in the X-axis direction indicated by the sub acceleration data referred to in step 105, and advances the processing to the next step. For example, the CPU 30 has a magnitude corresponding to the magnitude of the acceleration in the X-axis direction in a direction parallel to the virtual horizontal plane and orthogonal to the ball movement vector (the direction is determined by the sign of the acceleration data in the X-axis direction). The vector is added to the current ball movement vector, and the movement vector data Dc is updated.

As a result, the movement direction of the ball object B is controlled by the direction indicating unit (stick 78a) provided in the subunit 76, and the movement direction of the ball object B is output from the acceleration sensor 761 provided in the subunit 76. It is corrected according to the acceleration data. That is, the player can input the movement direction control and movement direction correction control of the ball object B efficiently and intuitively with one hand. The direction of the correction vector may be a fixed direction (virtual vertical direction, virtual horizontal direction, etc.) in the virtual game space, or a direction based on the visual line direction of the virtual camera (perpendicular to the visual line direction or the visual line direction). Direction), a direction based on the moving direction determined by the direction indicating unit (such as a direction orthogonal to the moving direction), or a predetermined axial direction in the local coordinate system of the player character PC even not good.

  Next, the CPU 30 refers to the history of core acceleration data included in the operation information transmitted from the player mode core unit of the team X based on the operation information Da, and the acceleration for the most recent predetermined time generated in each of the XYZ axis directions. An average is calculated (step 109). Then, the CPU 30 determines whether or not the average acceleration magnitude in the Z-axis direction calculated in step 109 is equal to or greater than a predetermined value (step 110). Then, when the acceleration average magnitude in the Z-axis direction is equal to or greater than a predetermined value, the CPU 30 advances the process to step 111. On the other hand, if the average acceleration in the Z-axis direction is less than the predetermined value, the CPU 30 advances the process to step 112.

  In step 111, the CPU 30 increases the magnitude of the ball movement vector. For example, a predetermined value may be added, multiplied by n (n> 1), or increased according to the average acceleration magnitude in the Z-axis direction calculated in step 109.

  In step 112, the CPU 30 determines whether or not the average acceleration magnitude in the Y-axis direction calculated in step 109 is equal to or greater than a predetermined value. As is clear from FIG. 5 and the like, when the core unit 70 is held horizontally, the gravitational acceleration always acts in the negative Y-axis direction. It is preferable to set. Then, when the average acceleration magnitude in the Y-axis direction is equal to or greater than a predetermined value, the CPU 30 advances the process to step 113. On the other hand, if the average acceleration magnitude in the Y-axis direction is less than the predetermined value, the CPU 30 advances the process to step 114.

  In step 113, the CPU 30 adds the vertical upward vector to the ball movement vector to update the movement vector data Dc, and proceeds to the next step 114. The magnitude of the vertical upward vector may be a fixed magnitude, or may be a magnitude corresponding to the average acceleration magnitude in the Y-axis direction calculated in step 109.

  In step 114, the CPU 30 determines whether or not the average acceleration in the X-axis direction calculated in step 109 is equal to or greater than a predetermined value. Then, when the acceleration average magnitude in the X-axis direction is equal to or greater than a predetermined value, the CPU 30 advances the process to step 115. On the other hand, when the acceleration average magnitude in the X-axis direction is less than the predetermined value, the CPU 30 ends the process by the subroutine and proceeds to the process of step 18.

  In step 115, the CPU 30 adds a vector in a direction parallel to the virtual horizontal plane and orthogonal to the ball movement vector (the direction is determined by the positive / negative acceleration average in the X-axis direction) to the current ball movement vector, and moves The vector data Dc is updated. Then, the CPU 30 ends the process by the subroutine and proceeds to the process of step 18 above. Note that the magnitude of the vector in the orthogonal direction may be a magnitude corresponding to the magnitude of the average acceleration in the X-axis direction calculated in step 109.

  Thus, when a predetermined operation button (in the above example, the operation button of the core unit 70 is used but the operation button of the subunit 76 may be operated), the character (ball object B) starts to move, and the movement direction is It is determined based on the direction indicated by the direction indicator of the subunit 76. Further, the moving direction is corrected according to the output of the acceleration sensor 701 of the core unit 70 before the predetermined operation button is operated (typically, the most recent predetermined operation before the predetermined operation button is operated). The output of the acceleration sensor 701 in time is used). Thus, the player can efficiently and intuitively input the movement direction control and the movement direction correction control of the ball object B independently with each hand. The moving direction may be corrected according to the output of the acceleration sensor 761 before operating the predetermined operation button. The direction of the correction vector may be a predetermined direction (typically, the direction of any axis) in the coordinate system of the virtual game space, may be a predetermined direction in the camera coordinate system, It may be a predetermined direction in the local coordinate system, a coordinate system obtained by projecting the camera coordinate system onto a virtual horizontal plane, or a direction based on the moving direction determined by the direction indicating unit (perpendicular to the moving direction) Direction). Thereby, the player can input the moving direction control and the moving direction correction control of the ball object B efficiently and intuitively.

  Further, in the first shoot process in step 17, the player character PC that keeps the ball object B performs a shooting action when the player simultaneously presses the A and B buttons. The initial velocity and the initial direction in which the player character PC shoots are indicated by the direction in which the player character PC faces, the magnitude of acceleration indicated by the core acceleration data obtained from the core unit 70, and the sub acceleration data obtained from the subunit 76. It is determined by the magnitude of acceleration. That is, the initial trajectory that the player character PC shoots is not determined only by a simple button operation, but is determined according to the movements of the core unit 70 and the subunit 76 as a whole when the player performs a shoot operation. . Therefore, the player can shoot with a degree of freedom while moving the entire core unit 70 and the subunit 76, and a realistic soccer game can be realized.

  Next, with reference to FIG. 22, the detailed operation of the second chute process in step 18 will be described.

  In FIG. 22, the CPU 30 refers to the history of the core key data included in the operation information transmitted from the player mode core unit of the team X from the operation information Da (step 121). Next, based on the core key data referred to in step 121, the CPU 30 determines whether the player has pressed the operation unit 72d (A button) and the operation unit 72i (B button) of the core unit 70 at the same time. It is determined whether or not (step 122). And CPU30 advances a process to the following step 123, when it is within predetermined time, after a player presses A and B button simultaneously. On the other hand, if it is not within a predetermined time since the player simultaneously pressed the A and B buttons, the CPU 30 ends the process by the subroutine and proceeds to the process of step 19.

  In step 123, the CPU 30 refers to the latest core acceleration data included in the operation information transmitted from the player mode core unit of the team X from the operation information Da. Then, the CPU 30 determines whether or not the magnitude of the acceleration in the Z-axis direction indicated by the core acceleration data referred to in step 123 is equal to or greater than a predetermined value (step 124). If the magnitude of acceleration in the Z-axis direction is equal to or greater than a predetermined value, the CPU 30 advances the process to step 125. On the other hand, if the magnitude of acceleration in the Z-axis direction is less than the predetermined value, the CPU 30 advances the process to step 126.

  In step 125, the CPU 30 increases the magnitude of the ball movement vector. For example, a predetermined value may be added, n times (n> 1), or increased according to the magnitude of acceleration in the Z-axis direction indicated by the core acceleration data referred to in step 123 above. Also good.

  In step 126, the CPU 30 determines whether or not the magnitude of the acceleration in the Y-axis direction indicated by the core acceleration data referenced in step 123 is equal to or greater than a predetermined value. As is clear from FIG. 5 and the like, when the core unit 70 is held horizontally, the gravitational acceleration always acts in the negative Y-axis direction, so the determination criterion in step 126 is also a predetermined value considering the gravitational acceleration. It is preferable to set. If the magnitude of acceleration in the Y-axis direction is equal to or greater than a predetermined value, the CPU 30 advances the process to step 127. On the other hand, if the magnitude of acceleration in the Y-axis direction is less than the predetermined value, the CPU 30 advances the process to step 128.

  In step 127, the CPU 30 adds the vertical upward vector with respect to the virtual game space to the ball movement vector to update the movement vector data Dc, and proceeds to the next step 128. Here, the magnitude of the vector in the vertical direction may be a fixed magnitude, or may be a magnitude corresponding to the magnitude of the acceleration in the Y-axis direction indicated by the core acceleration data referenced in step 123.

  In step 128, the CPU 30 determines whether or not the magnitude of the acceleration in the X-axis direction indicated by the core acceleration data referred to in step 123 is equal to or greater than a predetermined value. If the magnitude of the acceleration in the X-axis direction is equal to or greater than a predetermined value, the CPU 30 advances the process to step 129. On the other hand, when the magnitude of the acceleration in the X-axis direction is less than the predetermined value, the CPU 30 ends the process by the subroutine and proceeds to the process of step 19 above.

  In step 129, the CPU 30 adds a vector in the direction parallel to the virtual horizontal plane and orthogonal to the ball movement vector (the direction is determined by the positive / negative acceleration in the X-axis direction) to the current ball movement vector, Data Dc is updated. Here, the magnitude of the vector in the orthogonal direction may be a fixed magnitude, or may be a magnitude corresponding to the magnitude of the acceleration in the X-axis direction indicated by the core acceleration data referenced in step 123. Then, the CPU 30 ends the process by the subroutine and proceeds to the process of step 19 above.

  Thus, when a predetermined operation button (in the above example, the operation button of the core unit 70 is used but the operation button of the subunit 76 may be operated), the character (ball object B) starts to move, and the movement direction is It is determined based on the direction indicated by the direction indicator of the subunit 76. Further, the moving direction is corrected according to the output of the acceleration sensor 701 of the core unit 70 after the predetermined operation button is operated (typically, the most recent predetermined time immediately after the predetermined operation button is operated). The output of the acceleration sensor 701 in FIG. Thus, the player can efficiently and intuitively input the movement direction control and the movement direction correction control of the ball object B independently with each hand. Note that the moving direction may be corrected according to the output of the acceleration sensor 761 after operating the predetermined operation button. Further, it may be a predetermined direction (typically, the direction of any axis) in the coordinate system of the virtual game space, a predetermined direction in the camera coordinate system, or a predetermined direction in the local coordinate system. Or a coordinate system obtained by projecting the camera coordinate system onto a virtual horizontal plane, or a direction based on the moving direction determined by the direction indicating unit (such as a direction orthogonal to the moving direction). Also good. Thereby, the player can input the moving direction control and the moving direction correction control of the ball object B efficiently and intuitively.

  As described above, in the second shooting process in step 18, the ball trajectory after the player performs the shooting operation by simultaneously pressing the A and B buttons is determined according to the core acceleration data obtained from the core unit 70. The moving direction, the moving distance, etc. are determined. For example, as shown in FIG. 28, the trajectory a determined by the ball movement vector Vmb of the ball object B can be changed to a trajectory b or a trajectory c according to the core acceleration data obtained from the core unit 70. It is. That is, while the movement control of the player character PC is performed by the direction input, the trajectory after shooting is not determined only by a simple button operation, but the entire operation of the core unit 70 after the player performs the shooting operation. It is decided according to. Therefore, the player can intuitively change the shooting trajectory while moving the entire core unit 70 while controlling the moving direction of the player character PC, and a realistic soccer game can be realized.

  Next, with reference to FIG. 23, detailed operation | movement is demonstrated about the temporary supervision mode process in the said step 19. FIG.

  In FIG. 23, the CPU 30 refers to the latest core key data included in the operation information transmitted from the player mode core unit of the team X from the operation information Da (step 131). Next, the CPU 30 determines whether or not the player is pressing the upward direction of the operation unit 72a (cross key) of the core unit 70 based on the core key data referred to in the above step 131 (step 132). Then, when the player presses the upward direction of the cross key, the CPU 30 advances the process to the next step 133. On the other hand, when the player has not pressed the upward direction of the cross key, the CPU 30 proceeds to the next step 136.

  In step 133, the CPU 30 refers to the latest core acceleration data included in the operation information transmitted from the player mode core unit of the team X from the operation information Da. Next, the CPU 30 determines whether or not the magnitude of the acceleration in the X-axis direction indicated by the core acceleration data is greater than or equal to a predetermined value (step 134). Then, when the magnitude of acceleration in the X-axis direction is equal to or greater than a predetermined value, the CPU 30 proceeds to the next step 135. On the other hand, when the magnitude of the acceleration in the X-axis direction is less than the predetermined value, the CPU 30 advances the process to the next step 136.

  In step 135, the CPU 30 updates the movement vectors of all the non-player characters NPC of the team X based on the magnitude of the acceleration in the X-axis direction indicated by the core acceleration data referenced in step 133, and the movement vector data Dc. And the process proceeds to the next step 136. For example, as shown in FIG. 29, the CPU 30 adds a correction vector in a direction parallel to the touch line of the soccer field set in the virtual game space to the movement vector of all the non-player characters NPC of the team X, and performs a new movement. A vector Vmnpc is calculated. The correction vector may be a fixed magnitude or a magnitude corresponding to the magnitude of the acceleration in the X-axis direction. The direction of the correction vector may be determined according to the direction of acceleration indicated by the core acceleration data. In this case, the following examples can be considered.

  As a first example of determining the direction of the correction vector, each axis of the core acceleration data is associated with each of the three orthogonal directions of the virtual game space coordinates (typically corresponding to each axis of the virtual space coordinates) In addition, the output vector of the core acceleration data is converted into a direction vector of the virtual game space.

  As a second example of determining the direction of the correction vector, each axis of the core acceleration data is associated with each axis of the local coordinate system of a predetermined character (player character PC or the like), and an output vector of the core acceleration data is obtained. , Convert to the direction vector of the virtual game space.

  As a third example of determining the direction of the correction vector, each axis of the core acceleration data is associated with each axis of the camera coordinate system (or an axis obtained by projecting the X and Z axes of the camera coordinate system onto the virtual horizontal plane). Then, the output vector of the core acceleration data is converted into a virtual space direction vector.

  As a fourth example of determining the direction of the correction vector, each axis of the core acceleration data is associated with the moving direction vector (or direction vector) of the predetermined character and two directions orthogonal thereto, and the output vector of the core acceleration data Is converted into a direction vector of the virtual game space.

  In the process of step 135, the output of the sub acceleration data may be used instead of the core acceleration data.

  In the process of step 135, the movement vector of the player character PC of the team X may be updated by performing the same vector addition. Further, any of the non-player characters NPC of Team X (for example, the goalkeeper of Team X) may be excluded from the vector addition target. In the above-described processing, an example in which a vector having a magnitude corresponding to the magnitude of acceleration in the X-axis direction in the direction parallel to the touch line is shown. However, the vector is used as it is for all non-player characters NPC of team X. It may be set to the movement vector. Furthermore, the direction of the vector to be added may be set to a horizontal direction perpendicular to the direction in which the visual direction vector of the virtual camera is projected onto the virtual horizontal plane of the virtual game space, or another direction based on the visual direction. It doesn't matter. In general, the direction of the acceleration vector detected by the acceleration sensor 701 when the core unit 70 starts to move in a certain direction is opposite to the moving direction, and thus the acceleration vector detected at that time is detected. You can use it in the opposite direction. In addition, since the direction of the acceleration vector detected by the acceleration sensor 701 when the core unit 70 is moved in a certain direction and then stopped is the movement direction, the detection at that time may be used. Absent. This is the same for the same processing described elsewhere in this specification.

  In this way, the core acceleration data in which the moving direction of the player character PC is controlled by the stick 78 a of the subunit 76 and the moving directions of a plurality of non-player characters NPC (may include the player character PC) are obtained from the core unit 70. (Or may be sub acceleration data). That is, the player can control the movement direction of a plurality of characters by the movement of the entire core unit 70 (or the entire subunit 76) while controlling the movement direction of the specific character with the direction instruction means. Therefore, the player can intuitively operate the moving directions of the plurality of characters while controlling the moving direction of the specific character with the direction instruction means.

  In step 136, the CPU 30 determines whether or not the player is pressing down the cross key of the core unit 70 based on the core key data referenced in step 131. Then, when the player presses the downward direction of the cross key, the CPU 30 advances the processing to the next step 137. On the other hand, when the player has not pressed the down direction of the cross key, the CPU 30 ends the process by the subroutine and proceeds to the next step 20.

  In step 137, the CPU 30 refers to the latest first coordinate data Da1 and second coordinate data Da2 included in the operation information transmitted from the player mode core unit of the team X from the operation information Da. Next, the CPU 30 calculates the instruction coordinates corresponding to the first coordinate data Da1 and the second coordinate data Da2 referred to in step 137 and the virtual space position corresponding to the instruction coordinates, and each player mode of the team X The instruction coordinate data De and the virtual space position coordinate data Df corresponding to the core unit for use are updated (step 138), and the process proceeds to the next step. Note that the method of calculating the designated coordinates and the virtual space position calculated in step 138 is the same as that in step 84, and a detailed description thereof will be omitted.

  Next, the CPU 30 refers to the instruction target player data Dg and determines whether or not the instruction target player of the player mode controller 7 of the team X is set (step 139). And CPU30 advances a process to the following step 141, when an instruction | indication object player is not set. On the other hand, when the instruction target player is set, the CPU 30 advances the processing to the next step 143.

  In step 141, the CPU 30 determines whether any of the player characters of the team X is arranged in the area A (see FIG. 27) centered on the virtual space position calculated in step 138. Next, when the player character of team X is arranged in the area A, the CPU 30 sets the player character as an instruction target player of the player mode controller 7 of team X and instructs the character identification number and the like. This is described in the target player data Dg (step 142). When there are a plurality of player characters of team X in the area A, the player character closest to the virtual space position calculated in step 138 is set as the instruction target player. Then, the CPU 30 ends the process by the subroutine and proceeds to the next step 20. On the other hand, when no player character of team X is arranged in the area A, the CPU 30 ends the process by the subroutine as it is and proceeds to the next step 20.

  In step 143, the CPU 30 determines whether or not the calculated virtual space coordinates are within the soccer field set in the virtual game space. Next, when the virtual space coordinates are within the soccer field, the CPU 30 sets the movement vector of the instruction target player according to the virtual space position and updates the movement vector data Dc (step 144). For example, the CPU 30 sets the direction from the current arrangement position of the instruction target player to the virtual space position TP (see FIG. 27) as the direction of the movement vector of the instruction target player. Furthermore, a size corresponding to the virtual distance from the current arrangement position to the virtual space position TP may be set as the size of the movement vector of the instruction target player. Then, the CPU 30 clears the instruction target player of the player mode controller of the team X described in the instruction target player data Dg (step 145), ends the processing by the subroutine, and advances the processing to the next step 20. . On the other hand, when the virtual space coordinates are outside the soccer field, the CPU 30 ends the process by the subroutine as it is and proceeds to the next step 20. In step 145, it is not necessary to clear the instruction target player. In this case, after setting the instruction target player, it is possible to issue a movement instruction to the instruction target player a plurality of times (this In this case, the clearing process may be performed according to a button operation or a coordinate instruction to a predetermined area).

  Next, with reference to FIG. 24, the detailed operation of the supervisor mode processing in step 20 will be described.

  In FIG. 24, the CPU 30 refers to the controller identification number data Db and determines whether or not the supervisor mode controller identification number is set for the team X (step 151). When the controller identification number for the supervisor mode is set for the team X, the CPU 30 proceeds to the next step 152. On the other hand, when the controller identification number for the supervisor mode is not set for the team X, the CPU 30 ends the process by the subroutine and proceeds to the next step 21.

  In step 152, the CPU 30 refers to the latest core acceleration data included in the operation information transmitted from the team mode X supervisory mode unit unit from the operation information Da. Next, the CPU 30 determines whether or not the magnitude of the acceleration in the X-axis direction indicated by the core acceleration data is greater than or equal to a predetermined value (step 153). Then, the CPU 30 proceeds to the next step 154 when the magnitude of acceleration in the X-axis direction is equal to or greater than a predetermined value. On the other hand, if the magnitude of acceleration in the X-axis direction is less than the predetermined value, the CPU 30 advances the process to the next step 155.

  In step 154, the CPU 30 updates the movement vector data Dc for all the non-player characters NPC of the team X based on the magnitude of the acceleration in the X-axis direction indicated by the core acceleration data referred to in step 152, and the movement vector data Dc. And the process proceeds to the next step 155. For example, as shown in FIG. 29, the CPU 30 adds a correction vector in a direction parallel to the touch line of the soccer field set in the virtual game space to the movement vector of all the non-player characters NPC of the team X, and performs a new movement. A vector Vmnpc is calculated. The correction vector may be a fixed magnitude or a magnitude corresponding to the acceleration magnitude in the X-axis direction. The direction of the correction vector may be determined according to the direction of acceleration indicated by the core acceleration data. Specifically, this is the same as the first to fourth examples for determining the direction of the correction vector described above.

  In the process of step 154, similar to the process of step 135, the movement vector of the player character PC of team X may be updated by performing the same vector addition. Further, any of the non-player characters NPC of Team X (for example, the goalkeeper of Team X) may be excluded from the vector addition target. In the above-described processing, an example in which a vector having a magnitude corresponding to the magnitude of acceleration in the X-axis direction in the direction parallel to the touch line is shown. However, the vector is used as it is for all non-player characters NPC of team X. It may be set to the movement vector. Furthermore, the direction of the vector to be added may be set to a horizontal direction perpendicular to the direction in which the visual direction vector of the virtual camera is projected onto the virtual horizontal plane of the virtual game space, or another direction based on the visual direction. It doesn't matter.

  In step 155, the CPU 30 refers to the latest first coordinate data Da <b> 1 and second coordinate data Da <b> 2 included in the operation information transmitted from the operation mode Da from the manager mode core unit of the team X. Next, the CPU 30 calculates the instruction coordinates corresponding to the first coordinate data Da1 and the second coordinate data Da2 referred to in step 155 and the virtual space position corresponding to the instruction coordinates, and each of the team X supervisory modes. The instruction coordinate data De and the virtual space position coordinate data Df corresponding to the core unit for use are updated (step 156), and the process proceeds to the next step. Note that the method of calculating the designated coordinates and the virtual space position calculated in step 156 is the same as that in step 84, and a detailed description thereof will be omitted.

  Next, the CPU 30 refers to the instruction target player data Dg to determine whether or not an instruction target player of the team X manager mode controller 7 is set (step 157). And CPU30 advances a process to the following step 158, when an instruction | indication object player is not set. On the other hand, when the instruction target player is set, the CPU 30 advances the processing to the next step 160.

  In step 158, the CPU 30 determines whether any of the player characters of the team X is placed in the area A (see FIG. 27) centered on the virtual space position calculated in step 156. Next, when a team X player character is arranged in the area A, the CPU 30 sets the player character as an instruction target player of the team X manager mode controller, and specifies the character identification number and the like. This is described in the player data Dg (step 159). When there are a plurality of player characters of team X in the area A, the player character closest to the virtual space position calculated in step 138 is set as the instruction target player. Then, the CPU 30 ends the process by the subroutine and proceeds to the next step 21. On the other hand, if no player character of team X is arranged in the area A, the CPU 30 ends the process by the subroutine as it is and proceeds to the next step 21.

In step 160, the CPU 30 determines whether or not the calculated virtual space coordinates are within the soccer field set in the virtual game space. Next, when the virtual space coordinates are within the soccer field, the CPU 30 sets the movement vector of the instruction target player according to the virtual space position and updates the movement vector data Dc (step 161). For example, the CPU 30 sets the direction from the current arrangement position of the instruction target player to the virtual space position TP (see FIG. 27) as the direction of the movement vector of the instruction target player. Furthermore, a size corresponding to the virtual distance from the current arrangement position to the virtual space position TP may be set as the size of the movement vector of the instruction target player. Then, the CPU 30 clears the instruction target player of the team X manager mode controller described in the instruction target player data Dg (step 162), ends the processing by the subroutine, and proceeds to the next step 21. . On the other hand, if the virtual space coordinates are outside the soccer field, the CPU 30 ends the processing by the subroutine as it is and proceeds to the next step 21. In step 162 , it is not necessary to clear the instruction target player. In this case, after setting the instruction target player, it is possible to issue a movement instruction to the instruction target player a plurality of times ( In this case, the clearing process may be performed according to a button operation or a coordinate instruction to a predetermined area).

  As described above, in the manager mode processing in step 20, the controller 7 operated by the player is set to the manager mode, whereby a comprehensive operation can be performed on the entire team. Specifically, the movement direction of a plurality of non-player characters NPC (may include the player character PC) in the team is controlled according to core acceleration data (or sub-acceleration data) obtained from the core unit 70. Is done. That is, the player can control the movement direction of a plurality of characters by the action of the entire core unit 70 (or the entire subunit 76). Therefore, the player can intuitively operate the movement directions of the plurality of characters in the supervisor mode.

  As is clear from the processing of the flowchart described above, the procedure for operating the cross key is different in the temporary supervision mode processing in step 19, but the other processing is similar to the supervision mode processing in step 20. That is, even when the controller 7 operated by the player is set to the player mode, the same operation as the above-described manager mode can be performed by operating the up and down direction of the cross key.

  Further, in the process of step 22, when each of the movement vector data described in the movement vector data Dc is attenuated by a predetermined amount, but it is desired to continuously operate until the non-player character NPC reaches a predetermined point, The movement vector of the non-player character NPC need not be attenuated. For example, when it is desired to move the instruction target player to the virtual space position TP indicated by the core unit 70, the size and direction of the movement vector of the instruction target player are maintained until the instruction target player reaches the virtual space position TP. It doesn't matter.

  Further, in the above description, in order to specify coordinates remotely from the display screen, the image data obtained by imaging the imaging target by the imaging element 743 provided in the core unit 70 is analyzed, and thereby the display screen of the monitor 2 is displayed. For this, the coordinate designation mode was used. In this aspect, two markers to be imaged are installed in the vicinity of the display screen, and a device including an imaging unit and a housing capable of freely changing the imaging direction detects the two markers in the captured image, and the imaging The coordinate position designated by the device is derived based on the position of the marker in the image. However, the coordinate designation may be performed in another manner.

  For example, the imaging target placed in the vicinity of the display screen may be a member that reflects light, or a physical marker having a specific color or shape, in addition to the electrical marker (LED module) described above. Further, the imaging target may be displayed on the display screen of the monitor 2. Further, the monitor itself may be set as the imaging target by reading the scanning line of the raster scan type monitor with the imaging means provided in the core unit 70. Further, a magnetic generator may be provided, and coordinates may be specified from a remote location using magnetism generated from the magnetic generator. In this case, the core unit 70 is provided with a magnetic sensor for detecting the magnetism.

  Further, in the above description, the infrared light from the two markers 8L and 8R is the imaging target of the imaging information calculation unit 74 of the core unit 70, but other objects may be the imaging target. For example, one or three or more markers may be installed in the vicinity of the monitor 2, and infrared light from these markers may be used as an imaging target of the imaging information calculation unit 74. For example, even if one marker having a predetermined length is installed in the vicinity of the monitor 2, the present invention can be similarly realized. In addition, the display screen itself of the monitor 2 or other light emitters (such as room lights) may be the imaging target of the imaging information calculation unit 74. If the position of the core unit 70 relative to the display screen is calculated based on the positional relationship between the imaging target and the display screen of the monitor 2, various light emitters can be used as the imaging target of the imaging information calculation unit 74.

  Further, an imaging target such as a marker may be provided on the core unit 70 side, and the imaging means may be provided on the monitor 2 side. In still another example, a mechanism for emitting light from the front surface of the core unit 70 may be provided. In this case, an imaging device that captures the display screen of the monitor 2 is installed at a location different from the core unit 70 and the monitor 2, and the position where the light emitted from the core unit 70 is reflected on the display screen of the monitor 2 is captured. By analyzing the image captured by the apparatus, a pointing device that can output data for remotely designating coordinates on the display screen can be configured.

  In the above description, the controller 7 and the game apparatus main body 5 are connected by wireless communication. However, the controller 7 and the game apparatus main body 5 may be electrically connected via a cable. . In this case, the core unit 70 and the subunit 76 are connected by the connection cable 79, and the core unit 70 and the game apparatus body 5 are connected by another cable.

  In addition, the shape of the controller 7 described above and the shapes, numbers, and installation positions of the operation units 72 and 78 provided in them are merely examples, and other shapes, numbers, and installation positions may be used. Needless to say, the present invention can be realized.

  The game program of the present invention may be supplied not only to the game apparatus body 5 through an external storage medium such as the optical disc 4 but also to the game apparatus body 5 through a wired or wireless communication line. The game program may be recorded in advance in a nonvolatile storage device inside the game apparatus body 5. The information storage medium for storing the game program may be a non-volatile semiconductor memory in addition to a CD-ROM, DVD, or similar optical disk storage medium.
