According to FIG. 5C, the player character 20 performs an action of swinging the weapon 30 in a direction coinciding with the swing direction, that is, from the top to the front-down direction. This swing direction is defined as “down”.

[principle]
The swinging motion of the weapon 30 by the player character 20 is controlled as follows. That is, when the swing operation by the player 10 is performed, the right arm of the player character 20 is controlled so as to swing the weapon 30 in the operation direction performed. Further, the movement trajectory of the weight 33 of the weapon 30 is set according to the swing direction made, and the weight 33 is controlled so as to move along the set movement trajectory.

(1) Determination of Swing Direction The swing operation performed by the player is determined based on accelerations αx, αy, αz detected by the acceleration sensor 1306 of the game controller 1300. Since the acceleration sensor 1306 always detects gravitational acceleration, a combined value of the gravity G and the movement acceleration F generated by the movement of the game controller 1300 by the swing operation is detected as the acceleration α. Gravity G is always generated vertically downward, and its magnitude is “1.0 G”. Further, the movement acceleration F is generated in the direction opposite to the swing direction, and the magnitude thereof is sufficiently larger than the gravity G and is “several G to about several tens of G”.

  First, the start of a swing operation, that is, the start of swinging of the game controller 1300 is detected. Specifically, it is determined that the swing operation has been started when the acceleration αz exceeds a predetermined threshold (specifically, a value larger than the magnitude of the gravity G. For example, “1.1 G”). This is because when the game controller 1300 is swung, a large centrifugal force is generated in the longitudinal direction, and this centrifugal force is detected as an acceleration αz in the Zc-axis direction that coincides with the longitudinal direction.

  If the start of the swing operation is determined, then sampling (capture) of the accelerations αx, αy, αz detected by the acceleration sensor 1306 is performed a predetermined number of times at a predetermined time interval (for example, a frame time interval). Done. Next, for each of the sampled acceleration components αx, αy, αz, average accelerations αxa, αya, αza, which are average values for each sampling, are calculated. Then, the operation direction of the swing operation is determined based on the average accelerations αxa, αya, αza.

  Here, the accelerations αx, αy, and αz detected by the acceleration sensor 1306 when the swing operation in each direction is performed will be briefly described. For the sake of simplicity, the acceleration component αz in the Z-axis direction will be omitted from the description.

  FIG. 8 shows a side view of the game controller 1300 viewed from the rear end 1314 side and accelerations αx and αy detected by the acceleration sensor 1306 in the case of “right swing operation”. In the right swing operation, the state in which the operation surface 1310 is kept vertical is an ideal state. However, as will be described later with reference to FIG. The right swing operation is detected even in a tilted state.

  As shown in the drawing, in the “ideal” state where the operation surface 1310 of the game controller 1300 is vertical, the direction of gravity G coincides with the negative direction of the Xc axis, and the direction of the detected movement acceleration F is the negative direction of the Yc axis. Matches. That is, in the “ideal” state, the acceleration αx is detected as “−G” in the negative direction with the magnitude of gravity G. However, in a state where the operation surface 1310 is “tilted to the left” with respect to the vertical direction, the acceleration αx is the sum of the Xc component “−Fx” of the moving acceleration F and the Xc component “− | Gx |” of the gravity G. “− | Fx | − | Gx |” is detected. Further, in a state where the operation surface 1310 is “inclined to the right” with respect to the vertical direction, the acceleration αx is expressed by the Fc component “+ | Fx |” of the movement acceleration F and the Xc component “− | Gx |” of the gravity G. "| Fx |-| Gx |" which is the sum of the two is detected.

  Here, the magnitudes of the movement acceleration Fx and the gravity Gx vary depending on the degree of inclination of the operation surface 1310. That is, when the inclination angle of the operation surface 1310 with respect to the vertical direction is “θ”, the movement acceleration Fx is given by Fx = F · sin θ, and the gravity Gx is given by Gx = G · cos θ. That is, the moving acceleration Fx gradually decreases from “0” as the leftward inclination of the operation surface 1310 increases, and gradually decreases from “0” as the rightward inclination increases. On the other hand, the gravitational acceleration Gx gradually decreases from “−G” as the inclination of the operation surface 1310 to the left and right increases. Accordingly, the detected acceleration αx is “− | G |” in the “ideal” state, and gradually decreases as the tilt angle θ toward the left increases, and increases as the tilt angle θ toward the right increases. Gradually grows. That is, if the inclination angle θ is small, that is, if the operation surface 1310 is kept substantially vertical, the acceleration αx is a value close to negative “− | G |” in the magnitude of the gravity G, that is, “−1”. About 0.0G "is detected.

  Further, in the “ideal” state, the magnitude “− | F |” of the movement acceleration F is detected as the acceleration αy. However, in the state where the operation surface 1310 is “tilted to the left”, the acceleration αy is the sum of the Yc component “− | Fy |” of the moving acceleration F and the Yc component “+ | Gy |” of the gravity G “ − | Fy | + | Gy | ”is detected. In the state where the operation surface 1310 is “tilted to the right”, the acceleration αy is the sum of the Yc component “− | Yc |” of the moving acceleration F and the Yc component “− | Gy |” of the gravity G “ − | Fy | − | Gy | ”is detected.

  Here, the magnitudes of the movement acceleration Fy and the gravity Gy differ depending on the degree of inclination of the operation surface 1310. That is, when the inclination angle of the operation surface 1310 with respect to the vertical direction is “θ”, the movement acceleration Fy is given by Fy = F · cos θ, and the gravity Gy is given by Gy = G · sin θ. That is, the movement acceleration αy gradually increases from “− | F |” as the left and right inclination of the operation surface 1310 increases. On the other hand, gravity Gx gradually increases from “0” as the leftward inclination of operation surface 1310 increases, and gradually decreases from “0” as the rightward inclination increases. Accordingly, the detected acceleration αy is “− | F |” in the “ideal” state, but gradually increases as the inclination angle θ to the left and right increases. However, the ascending curve is not symmetrical. That is, if the inclination angle θ is small, that is, if the operation surface 1310 is kept substantially vertical, the acceleration αy is a value close to negative “− | F |” in the magnitude of the moving acceleration F, that is, “−”. “Several tens of G to several G” is detected.

  FIG. 9 shows a side view of the game controller 1300 viewed from the rear end 1314 side and accelerations αx and αy detected by the acceleration sensor 1306 when the “left swing operation” is performed. In the left swing operation, as in the right swing operation, it is ideal that the operation surface 1310 is kept vertical. However, the operation surface 1310 is inclined with respect to the vertical direction according to the conditions determined by the direction determination table 321 in FIG. Even in this state, the left swing operation is detected.

  As shown in the figure, in the “ideal” state where the operation surface 1310 is vertical, the direction of gravity G coincides with the negative direction of the Xc axis, and the direction of detected acceleration F coincides with the positive direction of Yc. That is, in the “ideal” state, the acceleration αx is detected as “− | G |” in the negative direction with the magnitude of gravity G. However, in the state where the operation surface 1310 is “left tilted” with respect to the vertical direction, the acceleration αx is expressed as the Xc component “+ | Fx |” of the moving acceleration F and the Yc component “− | Gx |” of the gravity G. "| Fx |-| Gx |" which is the sum of the two is detected. When the operation surface 1310 is “slightly inclined to the right” with respect to the vertical direction, the acceleration αx includes the Xc component “− | Fx |” of the movement acceleration F and the Xc component “− | Gx |” of the gravity G. Is detected as “− | Fx | − | Gx |”.

  Here, the magnitudes of the movement acceleration Fx and the gravity Gx vary depending on the inclination angle θ of the operation surface 1310 with respect to the vertical direction. That is, the movement acceleration Fx is given by Fx = F · sin θ, and the gravity Gx is given by Gx = G · cos θ. That is, the movement acceleration Fx gradually increases from “0” as the leftward tilt angle θ of the operation surface 1310 increases, and gradually decreases from “0” as the rightward tilt increases. On the other hand, the gravity Gx gradually increases from “− | G |” as the inclination of the operation surface 1310 in the left-right direction increases. Therefore, the value of the detected acceleration αx is “− | G |” in the “ideal” state, but gradually increases as the tilt angle θ toward the left increases, and the tilt angle θ toward the right increases. It gets smaller gradually as it gets larger. That is, if the inclination angle θ is small, that is, if the operation surface 1310 is kept substantially vertical, the acceleration αx is a value close to negative “− | G |” in the magnitude of gravity G, that is, “−1”. About 0.0G "is detected.

  In the “ideal” state, the magnitude “F” of the movement acceleration F is detected as the acceleration αy. However, in the state where the operation surface 1310 is “tilted to the left”, the acceleration αy is the sum of the Yc component “+ | Fy |” of the moving acceleration F and the Yc component “+ | Gy |” of the gravity G “ Fy + Gy ”is detected. In the state where the operation surface 1310 is “inclined to the right”, the acceleration αy is the sum of the Yc component “Fy” of the moving acceleration F and the Yc component “− | Gy |” of the gravity G “| Fy |”. − | Gy | ”is detected.

  Here, the magnitudes of the movement acceleration Fy and the gravity Gy vary depending on the inclination angle θ of the operation surface 1310 with respect to the vertical direction. That is, the movement acceleration Fy is given by Fy = F · cos θ, and the gravity Gy is given by Gy = G · sin θ. That is, the movement acceleration Fy gradually decreases from “F” as the inclination of the operation surface 1310 in the left-right direction increases. On the other hand, the gravity Gy gradually increases from “0” as the leftward inclination of the operation surface 1310 increases, and gradually decreases from “0” as the rightward inclination increases. Therefore, the detected acceleration αy is “| F |” in the “ideal” state, and gradually decreases as the inclination angle θ in the left-right direction increases. However, the descending curve is not symmetrical. That is, if the inclination angle θ is small, that is, if the operation surface 1310 is kept substantially vertical, the acceleration αy is a value close to the magnitude “| F |” of the movement acceleration F, that is, “several G to several dozens”. "About G" is detected.

  FIG. 10 shows a side view of the game controller 1300 viewed from the rear end 1314 side and accelerations αx and αy detected by the acceleration sensor 1306 in the case of the “down swing operation”. In the swing-down operation, the state where the operation surface 1310 is directed upward and the horizontal direction (short direction) of the game controller 1300 is horizontal is an ideal state, but depending on the conditions determined by the direction determination table 321 in FIG. The swing-down operation is detected even in a state in which the direction (longitudinal direction) is tilted to the left and right about the axis center.

  As shown in the figure, in the “ideal” state where the left and right directions of the game controller 1300 are horizontal, the direction of gravity G coincides with the negative direction of the Yc axis, and the direction of the detected movement acceleration F is the positive direction of the Yc axis. Match. That is, in the “ideal” state, the acceleration αx is detected as “0”. However, in a state in which the left and right direction of the game controller 1300 is “tilted to the left” with respect to the horizontal direction, the acceleration αx includes the Xc component “| Fx |” of the movement acceleration F and the Xc component “− | Gx | "| Fx |-| Gx |" which is the sum of " In the state of “tilting right”, the acceleration αx is “− | Fx | +” which is the sum of the Xc component “− | Fx |” of the moving acceleration F and the Xc component “| Gx |” of the gravity G. | Gx | "is detected.

  Here, the movement acceleration Fx and the gravity Gx differ depending on the degree of inclination of the game controller 1300 in the left-right direction. That is, when the horizontal inclination angle with respect to the horizontal direction is “φ”, the movement acceleration Fx is given by Fx = F · sinφ, and the gravity Gx is given by Gx = G · sinφ. That is, the movement acceleration Fx gradually increases from “0” as the leftward inclination of the operation surface 1310 increases, and gradually decreases from “0” as the rightward inclination increases. On the other hand, the gravity Gx gradually increases from “0” as the leftward inclination of the operation surface 1310 increases, and gradually decreases from “0” as the rightward inclination increases. However, the magnitude “F” of the movement acceleration F is sufficiently larger than the magnitude “G” of the gravity G. Therefore, the detected acceleration αx is “0” in the “ideal” state, but gradually increases as the left inclination angle φ increases, and gradually decreases as the right inclination angle φ increases. Become. That is, if the inclination angle φ is small, that is, if the left and right direction of the game controller 1300 is kept substantially horizontal, a value of “0” is detected for the acceleration αx.

  In the “ideal” state, the acceleration αy is the sum of the Yc component “+ | F |” of the moving acceleration F and the Yc component “− | G |” of the gravity G “| F | − | G”. | "Is detected. However, in both the “tilt left” state and the “tilt right” state, the acceleration αy includes the Yc component “+ | Fy |” of the moving acceleration F and the Yc component “− | Gy” of the gravity G. “| Fy | − | Gy |” which is the sum of “|” is detected.

  Here, the movement acceleration Fy and the gravity Gy differ depending on the inclination angle φ. That is, the movement acceleration Fy is given by Fy = F · cos φ, and the gravity Gy is given by Gy = G · cos φ. That is, the movement acceleration Fx gradually decreases from “F” as the inclination of the operation surface 1310 in the left-right direction increases. On the other hand, the gravity Gx gradually increases from “− | G |” as the inclination of the operation surface 1310 in the left-right direction increases. Therefore, the detected acceleration αy is “| F | − | G |” in the “ideal” state, but gradually decreases as the tilt angle φ to the left and right increases. In other words, if the tilt angle φ is small and the left and right direction of the game controller 1300 is kept almost horizontal, the acceleration αy is a value close to “| F | − | G |”, that is, “ten to several G to several A value of “about G” is detected.

  By the way, when performing a swing-down operation as a swing operation, the player 10 raises the right hand holding the game controller 1300 upward and then swings the right hand down. In addition, the sampling of the detected acceleration α is started after it is determined that the value of the acceleration αz in the longitudinal direction of the game controller 1300 has exceeded a predetermined threshold value. That is, there is a possibility that the sampled accelerations αx, αy, αz are values of a period during which the swing-up operation, which is a stage before the swing-down operation intended by the player, is performed.

  FIG. 11 shows a side view of the game controller 1300 viewed from the rear end 1314 and accelerations αx and αy detected by the acceleration sensor 1306 in the case of this “swinging up operation”. In the swing-up operation, as in the swing-down operation, the state where the left-right direction of the game controller 1300 is kept horizontal is an ideal state, but even if the left-right direction is slightly inclined with respect to the horizontal direction, The swing-up operation can be detected according to the direction determination table 321 shown in FIG.

  As shown in the figure, in the “ideal” state in which the left and right direction of the game controller 1300 is horizontal, the directions of the detected movement acceleration F and gravity G coincide with the Yc axis negative direction. That is, in the “ideal” state, the acceleration αx is detected as “0”. However, in a state where the left-right direction is “tilted to the left” with respect to the horizontal direction, the acceleration αx is an Xc component “− | Fx |” of the moving acceleration F and an Xc component “− | Gx |” of the gravity G. The sum “− | Fx | − | Gx |” is detected. In the state where the left-right direction is “inclined to the right” with respect to the horizontal direction, the acceleration αx is an Xc component “+ | Fx |” of the moving acceleration F and an Xc component “+ | Gx |” of the gravity G. The sum “| Fx | + | Gx |” is detected.

  Here, the magnitudes of the movement acceleration Fx and the gravity Gx differ depending on the inclination angle φ of the game controller 1300 with respect to the horizontal direction in the left-right direction. That is, the movement acceleration Fx is given by Fx = F · sinφ, and the gravity Gx is given by Gx = G · sinφ. That is, both the movement acceleration Fx and the gravity Gx gradually decrease from “0” as the leftward inclination of the operation surface 1310 increases, and gradually increase from “0” as the rightward inclination increases. Become. Therefore, the detected acceleration αx is “0” in the “ideal” state, but gradually decreases as the tilt angle φ toward the left increases, and gradually increases as the tilt angle φ toward the right increases. growing. That is, if the inclination angle φ is small, that is, if the left and right direction of the game controller 1300 is kept substantially horizontal, a value of “0” is detected for the acceleration αx.

  In the “ideal” state, the acceleration αy is “− | F | − | G, which is the sum of the magnitude“ − | F | ”of the movement acceleration F and the magnitude“ − | G | ”of the gravity G. | "Is detected. However, in the state where the left-right direction of the game controller 1300 is “tilt left” and “tilt right”, the acceleration αy is the Yc component “− | Fy |” of the movement acceleration F and the gravity G "-| Fy |-| Gy |" which is the sum of Yc component "-| Gy |"

  Here, the magnitudes of the movement acceleration Fy and the gravity Gy differ depending on the inclination angle φ. That is, the movement acceleration Fy is given by Fy = F · cos φ, and the gravity Gy is given by Gx = G · cos φ. That is, the movement acceleration Fy gradually increases from “F” as the inclination of the operation surface 1310 in the left-right direction increases. Also, the gravity Gy gradually increases from “G” as the inclination of the operation surface 1310 in the left-right direction increases. Therefore, the detected acceleration αy is “− | F | − | G |” in the “ideal” state, but gradually increases as the tilt angle φ to the left and right increases. In other words, if the inclination angle φ is small, that is, if the left and right direction of the game controller 1300 is kept almost horizontal, the acceleration αy is a value close to “− | F | − | G |”, that is, “−ten”. A value of “G˜about several G” is detected.

  As described above, the combinations of the values of the accelerations αx and αy detected by the acceleration sensor 1306 differ depending on the difference in the swing direction. For this reason, the swing direction made by the player is determined based on the combination of the values of the average accelerations αxa, αya calculated from the sampled accelerations αx, αy, αz.

(2) Control of the swinging motion of the weapon 30 of the player character 20 When the swing direction is determined, the swinging direction of the weapon 30 by the player character 20 is determined. The swing direction of the weapon 30 is one of three types, “right”, “left”, and “down”, and the swing direction is determined in a direction that matches the determined swing direction. That is, if the swing direction is “right”, the swing direction is “right”, and if the swing operation is “left swing”, the swing direction is “left”. If the swing operation is “down” or “up”, the swing direction is “down”.

  When the turning direction of the weapon 30 is determined, the movement trajectory of the weight 33 of the weapon 30 is then determined. That is, when the swinging direction is “right”, a curved trajectory on the horizontal plane that passes forward from the right position of the player character 20 to the left position is set as the movement trajectory. When the swinging direction is “left”, a curved trajectory on the horizontal plane that passes from the left position of the player character 20 to the right position through the front is set as the movement trajectory. When the swing direction is “down”, a curved trajectory on the vertical plane extending from the position above the player character 20 to the front lower direction is set as the movement trajectory.

  Specifically, as shown in FIG. 12A, first, a plurality of reference control points Q corresponding to the turning direction are set in the game space. These reference control points Q are set on the reference trajectory serving as a reference for the moving trajectory determined for each swinging direction, and the reference trajectory is calculated by performing interpolation calculation on these reference control points Q. It has become. This figure shows a case where the swing direction is “right”. In this case, as the reference trajectory TR1, a curve on the horizontal plane from the start point Q1 defined at the right position of the player character 20 to the end point Q8 defined at the left position passing through the front of the player character 20 is shown. A plurality of reference control points Q are set along the reference trajectory TR1.

Then, as shown in FIG. 2B, the trajectory control point R is set based on these reference control points Q. According to the figure, the trajectory control point R is on a straight line connecting the position Pp of the player character 20 and each reference control point Q and the distance r from the position Pp satisfies the following expression (1). Is set.
r = (αm / αp) × s (1)
Here, “αp” is a predetermined reference acceleration. “Αm” is the maximum value (maximum acceleration) of the sampled acceleration α (= √ (αx ² + αy ² + αz ² )). “S” is a distance from the position Pp to the reference control point Q, and is determined in advance.

  That is, with reference to the position Pp of the player character 20, the position of the reference control point Q is changed in accordance with the ratio between the detected maximum acceleration αm and a predetermined reference acceleration αp, whereby the trajectory control point R is changed. Is set. That is, the trajectory control point R is set at a position farther from the player character position Pp as the maximum acceleration αm is larger. However, the start point R1 and the end point R8 are fixed. Then, by performing a predetermined interpolation calculation (for example, spline interpolation) based on these trajectory control points R, a moving trajectory TR2 from the start point R1 through the trajectory control points R to the end point R8 is set.

  Further, as shown in FIG. 13A, these trajectory control points R are corrected based on the positional relationship with the enemy character 40. According to the figure, for each trajectory control point R, it is determined whether or not the enemy character 40 is positioned within a predetermined collision determination area JA. If the enemy character 40 is positioned, the position of the enemy character 40 is determined. The trajectory control point R is changed (corrected). The collision determination area JA is an area in which the weight 33 of the weapon 30 is caused to collide with the enemy character 40, and is set here as an area inside the sphere centered on the trajectory control point R. In the figure, the enemy character 40 is located in the collision determination area JA of the trajectory control point R4, and the trajectory control point R4 is changed to the position Pe of the enemy character 40.

  Then, as shown in FIG. 5B, by performing an interpolation calculation based on each changed trajectory control point R, a moving trajectory TR2 from the start point R1 through the respective trajectory control points R to the end point R8 is calculated. The This moving trajectory TR2 is deviated in the vicinity of the changed trajectory control point R4 as compared to the moving trajectory TR2 'based on the respective trajectory control points R before change indicated by dotted lines.

  12 and 13, the case where the swinging direction is “right” has been described, but the same applies to other cases. That is, when the swinging direction is “left”, a reference trajectory on the horizontal plane is determined which starts from the left position of the player character 20 and passes through the front of the player character 20 and ends at the position of the right hand. A plurality of reference control points Q are set in Further, when the swinging direction is “swing down”, a reference trajectory on a vertical plane starting from a position above the player character 20 and passing through the front of the player character 20 and ending at a position near the front is determined. A plurality of reference control points Q are set on the track.

  Further, the moving speed V of the weight 33 is determined based on the detected maximum acceleration αm. FIG. 14 is a diagram illustrating an example of the relationship between the maximum acceleration αm and the movement speed V. In the figure, a graph of the relationship between the maximum acceleration αm and the moving speed V is shown with the horizontal axis representing the maximum acceleration αm and the vertical axis representing the moving speed V. According to the figure, the moving speed V is set to increase in proportion to the maximum acceleration αm. The relationship between the maximum acceleration αm and the moving speed V may not be a proportional relationship as shown in FIG.

  Thereafter, the weight 33 is controlled to move along the set movement trajectory TR2 at the set movement speed V. Specifically, the position of the weight 33 on the movement trajectory TR2 is determined every unit frame time. Further, according to the position of the weight 33, the bending angle between adjacent blades constituting the blade 32 is larger than a predetermined angle (for example, 120 degrees or more) and closer to the sword pattern 31 and becomes larger. Thus, the blade 32 is controlled.

[Function configuration]
FIG. 15 is a block diagram showing a functional configuration of the game system 1. According to the figure, the game system 1 functionally includes an operation input unit 110, a processing unit 200, an image display unit 130, a sound output unit 140, a communication unit 150, and a storage unit 300. Configured.

  The operation input unit 110 receives an operation input by the player and outputs an operation signal corresponding to the operation to the processing unit 200. This function is realized by, for example, a button switch, lever, dial, mouse, keyboard, touch panel, various sensors, and the like. In FIG. 1, the game controller 1300 corresponds to this. The operation input unit 110 includes an acceleration sensor 1306 and outputs the detected accelerations αx, αy, αz to the processing unit 200.

  The processing unit 200 performs various arithmetic processes such as overall control of the game system 1, game progress, and image generation. This function is realized by, for example, a processor such as a CPU (CISC type, RISC type) or DSP, an arithmetic device such as an ASIC (gate array or the like), or a control program thereof. In FIG. 1, the CPU mounted on the control unit 1110 corresponds to this. In addition, the processing unit 200 mainly includes a game calculation unit 210 that performs calculation processing related to game execution, an image generation unit 230 that generates a game image based on various data obtained by processing of the game calculation unit 210, And a sound generator 240 for generating game sounds such as sound effects and BGM.

  The game calculation unit 210 executes various game processes based on operation signals input from the operation input unit 110, programs and data read from the storage unit 300, and the like. In the present embodiment, the game calculation unit 210 includes a swing direction determination unit 211, a trajectory calculation unit 212, and a movement control unit 213.

  The swing direction determination unit 211 determines the operation direction (swing direction) of the swing operation performed based on the accelerations αx, αy, αz detected by the acceleration sensor 1306. Specifically, when the acceleration αz exceeds a predetermined threshold (for example, “1.1G”) among the accelerations αx, αy, and αz detected by the acceleration sensor 1306, the swing operation is started (swing Sampling of each acceleration αx, αy, αz is started. That is, the input accelerations αx, αy, αz are captured a predetermined number of times at predetermined time intervals (for example, frame time intervals). Then, average accelerations αxa, αya, αza of the sampled accelerations αx, αy, αz are calculated. In addition, for each sampling, an acceleration α that is the magnitude of an acceleration vector obtained by combining the sampled accelerations αx, αy, and αz is calculated, and the maximum acceleration αm is extracted from the calculated acceleration α.

  The sampled acceleration α data is stored in the sampling data 325. FIG. 16 is a diagram illustrating an example of a data configuration of the sampling data 325. According to the figure, the sampling data 325 stores the detected acceleration 352b in association with each sampling timing 325a, and stores an average acceleration 352c and a maximum acceleration 352d. The sampling timing 325a is a sampling timing at predetermined time intervals (for example, frame time intervals). The acceleration 352b stores the values of the acquired accelerations αx, αy, αz and the value of the acceleration α.

  Next, the swing direction determination unit 211 refers to the direction determination table 321 based on the calculated average accelerations αxa, αya, αza, and swings the operation direction of the swing operation performed and the weapon 30 of the player character 20. Determine the direction.

  FIG. 17 is a diagram illustrating an example of a data configuration of the direction determination table 321. According to the figure, the direction determination table 321 stores an acceleration condition 321a, a swing direction 321b, and a swing direction 321c in association with each other. The acceleration condition 321a is a condition of the average acceleration values αy and αx. That is, the swing direction determination unit 211 determines the swing direction and the swing direction corresponding to the acceleration condition that satisfies the calculated combination of the average acceleration values αx and αy.

  The trajectory calculation unit 212 calculates the movement trajectory and the movement speed V of the weight 33 of the weapon 30 according to the swing direction determined by the swing direction determination unit 211. Specifically, according to the reference trajectory data 322, a reference control point Q corresponding to the determined swing direction is set in the game space. At this time, of course, the reference control point Q is set according to the direction of the player character 20.

  FIG. 18 is a diagram illustrating an example of a data configuration of the reference trajectory data 322. As illustrated in FIG. According to the figure, the reference trajectory data 322 stores the position of each reference control point 322a in association with each swinging direction 322b and stores a reference acceleration 322c. The position of the reference control point 322a is stored as a coordinate value according to the local coordinate system set for the player character.

  Next, the trajectory calculation unit 212 sets a trajectory control point R for each set reference control point Q based on the calculated maximum acceleration αm. That is, the trajectory control point R is set at a position on the straight line from the position Pp of the player character 20 toward the reference control point Q and the distance r from the position Pp satisfies the expression (1). However, among these reference control points Q, the start point Q1 and the end point Qn are used as the start point R1 and end point Rn of the trajectory control point R as they are.

  Subsequently, the trajectory calculation unit 212 refers to the applied damage table 324 for each set trajectory control point R, and determines whether or not the enemy character 40 is located in the collision determination area JA centered on the trajectory control point R. Determine. When the enemy character 40 is located, the trajectory control point R is changed to the position of the enemy character 40.

  FIG. 19 is a diagram illustrating an example of a data configuration of the imparted damage table 324. According to the figure, the applied damage table 324 stores a collision determination area 324b and a damage value 324c in association with each type of weapon 30 324a. The collision determination area 324b stores the value of the radius r of the collision determination area that is a spherical area. The damage value 324c stores a damage value to be given to the enemy character 40 determined that the corresponding weapon 30 has collided.

  Then, the trajectory calculation unit 212 performs a predetermined interpolation calculation (for example, spline interpolation) based on each set trajectory control point R to obtain a moving trajectory TR2 from the start point R1 through each trajectory control point R1 to the end point Rn. calculate.

  Further, the trajectory calculation unit 212 refers to the moving speed setting data 323 based on the extracted maximum acceleration αm and determines the moving speed V of the weight 33 of the weapon 30. The moving speed setting data 323 is data defining the relationship between the maximum acceleration αm and the moving speed V, for example, as shown in FIG. 14, for example, specifically, a functional expression representing a graph, the maximum acceleration αm and the moving speed. 4 is a data table in which values with V are associated with each other.

  Data on the calculated movement trajectory TR2 and movement speed V is stored in movement control data 326. FIG. 20 is a diagram illustrating an example of a data configuration of the movement control data 326. According to the figure, the movement control data 326 stores the position 326b associated with each path control point 326a and stores the calculated movement path 326c and the movement speed 326d. The position 326b is stored as a coordinate value according to the world coordinate system.

  The movement control unit 213 controls the weapon 30 that the player character 20 has. Specifically, with reference to the movement control data 326, the weight 33 of the weapon 30 is moved at the calculated movement speed V along the calculated movement trajectory TR2. Further, as the weight 33 moves, the angle between adjacent blades of the blade 32 is controlled to control the blade 32 in a suitable state. Specifically, the bending angle between adjacent blades corresponding to the joint of the joint structure is determined to be greater than a predetermined angle (for example, 120 degrees or more) and larger as the sword pattern 31 is closer.

  The collision determination unit 214 determines a collision between the weapon 30 and each enemy character 40. Specifically, a determination process (hit determination) is performed as to whether each of the enemy character 40 collides with the sword blade 32 and the weight 33 of the weapon 30 that are movement-controlled by the movement control unit 213. Then, with reference to the assigned damage table 324, damage corresponding to the part where the weapon 30 collides is given to the enemy character 40 determined to collide. That is, when the enemy character 40 collides with the weight 33 of the weapon 30, a damage value determined in association with the weapon 30 in the assigned damage table 324 is given, and when the enemy character 40 collides with the sword body 32, A damage value smaller than the above damage value (for example, 0.2 times the damage value of the weapon 30) is given.

  In FIG. 15, the image generation unit 230 generates a game image for displaying the game screen based on the calculation result by the game calculation unit 210, and outputs an image signal of the generated image to the image display unit 130. Based on the image signal from the image generation unit 230, the image display unit 130 displays the game screen while redrawing a screen of one frame at a predetermined unit time interval, for example, every 1/60 seconds. This function is realized by hardware such as CRT, LCD, ELD, PDP, and HMD. In FIG. 1, the display 1202 corresponds to this.

  The sound generation unit 240 generates game sounds such as sound effects and BGM used during the game, and outputs a sound signal of the generated game sound to the sound output unit 140. The sound output unit 140 outputs game sounds such as BGM and sound effects based on the sound signal from the sound generation unit 240. This function is realized by, for example, a speaker. In FIG. 1, the speaker 1204 corresponds to this.

  The communication unit 150 is connected to a communication line according to a control signal from the processing unit 200 and performs data communication with an external device. This function is realized by a wireless communication module, a wired communication cable jack, a control circuit, or the like. In FIG. 1, the communication device 1112 corresponds to this.

  The storage unit 300 stores a system program for realizing various functions for causing the processing unit 200 to control the game system 1 in an integrated manner, a program and data necessary for executing the game, and the processing unit 200 is used as a work area, and temporarily stores calculation results executed by the processing unit 200 according to various programs, input data input from the operation input unit 110, and the like. This function is realized by, for example, various IC memories, hard disks, CD-ROMs, DVDs, MOs, RAMs, VRAMs, and the like. In FIG. 1, the memory mounted on the control unit 1110 corresponds to this. In the present embodiment, the storage unit 300 stores a game program 310 as a program, and as data, a direction determination table 321, reference trajectory data 322, moving speed setting data 323, an applied damage table 324, and sampling data 325, movement control data 326, and character data 327 are stored. The character data 327 is data relating to various characters such as player characters and enemy characters appearing in the game, and stores current position coordinates, ability values, owned items (including the weapon 30), motion data, and the like.

[Process flow]
FIG. 21 is a flowchart for explaining the flow of the game processing of the present embodiment. This process is realized by the game calculation unit 210 executing the game program 310. According to the figure, the game calculation unit 210 first sets a game stage and sets a game space in which each character such as the player character 20 and the enemy character 40 is arranged (step A1). Next, in accordance with an input instruction from the operation input unit 110, the type of weapon 30 possessed by the player character 20 is switched (step A3). Further, according to an input instruction from the operation input unit 110, movement control of the player character 20 and control of other characters including the enemy character 40 are performed (step A5).

  Subsequently, the swing direction determination unit 211 determines whether or not the acceleration component αz of the game controller 1300 input from the acceleration sensor 1306 exceeds a predetermined threshold (for example, “1.1G”). If this is the case (step A7: YES), the game calculation unit 210 causes the player character 20 to start a predetermined swing-up operation of the weapon 30 (step A9). Further, the swing direction determination unit 211 performs a swing direction determination process to determine the swing direction of the game controller 1300 made by the player 10 (step A11).

FIG. 22 is a flowchart for explaining the flow of the swing direction determination process.
According to the figure, the swing direction determination unit 211 samples the accelerations αx, αy, αz input from the acceleration sensor 1306 a predetermined number of times at predetermined time intervals (for example, frame time intervals) (step B1). Next, average accelerations αxa, αya, αza which are average values of the sampled accelerations αx, αy, αz are calculated (step B3). Further, for each sampling, an acceleration α that is the magnitude of an acceleration vector obtained by combining the accelerations αx, αy, and αz is calculated, and the maximum acceleration αm that is the maximum value of these accelerations α is extracted (step B5). . Then, based on the calculated average accelerations αxa, αya, αza, the direction determination table 321 is referred to determine the performed swing direction (step B7). When the above processing is performed, the swing direction determination processing ends.

  When the swing direction determination process ends, the swing direction determination unit 211 refers to the direction determination table 321 and determines the swinging direction of the weapon 30 of the player character 20 based on the determined swing direction (step A13). Subsequently, the trajectory calculation unit 212 performs a movement trajectory calculation process to calculate the movement trajectory TR2 and the movement speed V of the weapon 30 (step A15).

  FIG. 23 is a flowchart for explaining the flow of the movement trajectory calculation process. According to the figure, the movement trajectory calculation unit 212 refers to the reference trajectory data 322, and sets each reference control point Q corresponding to the determined turning direction in the game space (step C1). At this time, each reference control point Q is set in accordance with the direction (orientation) of the player character 20 so that the turning direction is based on the player character 20. Next, for each set reference control point Q, a trajectory control point R is set based on the ratio between the calculated maximum acceleration αm and the reference acceleration αp (step C3). Subsequently, with reference to the assigned damage table 324, it is determined whether or not an enemy character is positioned in the collision determination area for each set trajectory control point R (step C5). The trajectory control point R is changed to a position (step C7). Thereafter, an interpolation calculation based on each of these movement control points R is performed to calculate the movement trajectory TR2 (step C9). Further, referring to the moving speed setting data 323, the moving speed V is calculated based on the maximum acceleration αm (step C11). When the above processing is performed, the movement trajectory calculation processing is terminated.

  When the movement trajectory calculation process ends, the game calculation unit 210 causes the player character 20 to start swinging the weapon 30 in the determined swing direction (step A17). In addition, the movement control unit 213 refers to the movement control data 326 and starts movement control of the weight 33 of the weapon 30 at the movement speed V calculated along the calculated movement trajectory TR2, and the blade 32 The angle between the adjacent blades is controlled to be within a predetermined angle, so that the blade 32 is in a suitable state. Specifically, for the rigid portion of the blade 32 from the starting point P1 to the control point R1, the bending angle between adjacent blades corresponding to the joint of the joint structure is set to 180 degrees, and the control point R The bent portion on the weight 33 side is determined so that the angle between adjacent blades is not less than a predetermined angle (for example, not less than 120 degrees), and the closer to the starting point P of the blade 32, the greater the bend angle. (Step B29). When the above processing is performed (step A19).

  Next, the collision determination unit 214 determines a collision between the weapon 30 and each enemy character 40 (step A21), and damages each enemy character 40 according to the collision determination result (step A23). Thereafter, the game calculation unit 210 determines whether or not to end the game. If the game is not ended (step A25: NO), the process returns to step A3. If the game is ended (step A25: YES), the game processing is performed. Exit.

[Action / Effect]
Thus, according to the present embodiment, a new game operation such as the player character 20 swinging the weapon 30 is realized by a swing operation of swinging the game controller 1300. That is, the operation direction (swing direction) of the swing operation performed is determined based on the value of the acceleration α detected by the acceleration sensor 1306 incorporated in the game controller 1300, and the player character is matched with this swing direction. The turning direction of the 20 weapons 30 is determined. Next, based on the determined swing direction of the weapon 30 and the maximum acceleration αm detected by the acceleration sensor 1306, the movement trajectory TR2 and the movement speed V of the weight 33 of the weapon 30 are calculated. Then, the weight 33 of the weapon 30 is controlled so as to move at the moving speed V along the moving trajectory TR2.

[Modification]
It should be noted that embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention.

(A) Moving trajectory TR2
For example, the moving trajectory TR2 may be varied according to the type of the weapon 30. Specifically, reference trajectory data 322 in which the position of the reference control point Q is different is stored in association with each type of weapon 30. Then, the movement trajectory TR2 is calculated by setting a reference control point Q based on the reference trajectory data 322 corresponding to the type of weapon 30 possessed by the player character 20.

(B) Trajectory control point R
Further, the trajectory control point R set in the game space may be notified to the player. Specifically, a predetermined mark body (object) serving as a mark is arranged at the position of each trajectory control point R. Accordingly, the weight 34 moves so as to pass through these landmarks. Of course, this landmark does not affect other objects such as the blade 32 and the weight 33 of the weapon 30.

  Further, the position of the trajectory control point R may be varied by a player's instruction operation. Specifically, in the above-described embodiment, the position of each trajectory control point R is set to a position where the distance r from the position Pp of the player character 20 is the distance r given by the above equation (1). However, this is set to a position where the distance r from the position Pp is a distance r ′ (= r × k) obtained by multiplying the distance r calculated by the expression (1) by a predetermined coefficient k. I will decide. The coefficient k is changed in accordance with a predetermined operation (for example, pressing of the operation button 1302) in the game controller 1300. For example, the coefficient k is set to “1.0” when the swing operation is detected in a state where the operation button 1302 is not pressed, and the coefficient k is set to “1.0” when the swing operation is detected in the pressed state. 1.5 ".

(C) Determination of Swing Operation In addition, the threshold value of the acceleration α for determining the operation direction of the swing operation may be changed by a player's instruction operation. Specifically, threshold values of average accelerations αx and αy defined as acceleration conditions in the direction determination table 321 shown in FIG. 17 (in the figure, αx is “0.9G” and αy is “0.0”), The game controller 1300 changes in accordance with a predetermined operation (for example, pressing of the operation button 1302). For example, when the operation button 1302 is not pressed, the threshold value determined in the direction determination table 321 is used, and when the operation button 1302 is pressed, the threshold value is increased or decreased (for example, “1.2 times” or “0.8 times”). )).

(D) Correction of Detected Acceleration α The accelerations αx, αy, and αz detected by the acceleration sensor 1306 may be corrected. Specifically, for example, when a predetermined operation (for example, pressing of the cross key 1304 or another operation button not shown) is performed on the game controller 1300, the values of the detected accelerations αx, αy, αz are multiplied by a predetermined value. (For example, “1.5 times” or “0.8 times”) may be used.

(E) Weapon In the above-described embodiment, the weapon 30 is similar to a “belly sword”, but other weapons may be used. For example, a weapon that simulates a “yoyo” in which a moving body of a certain size is attached to one end of a string-like body may be used. The string-like body may be an elastic body such as a rubber string or a spring. That is, the weapon 30 may be any one as long as it is configured to attack the enemy character 40 by swinging it around. Further, the weapon 30 does not have a connection body, for example, like a weapon imitating a “boomerang”, and does not have to be connected to the player character 20.

  Further, as shown in FIG. 24, the weapon 30 may not have the weight 33 but may have a sword pattern 31 and a sword 32. In this case, among the plurality of blades 34 connected in a bellows form the sword body 32, the blade 34a corresponding to the sword tip is controlled as a moving body instead of the weight 33, and the same control as in the above embodiment is performed. Further, when the weapon 30 shown in the figure collides with the enemy character 40, the damage value to be given to the enemy character 40 is varied depending on which of the plurality of blades 34 constituting the blade 32 has collided. Anyway.

(F) Player's dominant hand In the embodiment described above, the player is described as holding the game controller 1300 with the right hand, but the player may be able to set which hand to hold with the right or left hand. Specifically, as the direction determination table 321, in addition to the right hand shown as an example in FIG. Then, for example, before the game is started, whether the player holds with the right hand or the left hand is input and set, and the operation of the swing operation performed is performed using the direction determination table 321 of the input setting. Determine the direction.

(G) Game controller 1300
(G-1) Speaker In addition, the game controller 1300 may include a speaker. And you may decide to output the sound according to the magnitude | size of the acceleration (alpha) detected from the acceleration sensor 1306 from this speaker. In this case, for example, according to the magnitude of the acceleration α, one or two sound elements of the “sound”, “volume”, and “sound quality” constituting the “sound” are gradually changed. Output the sound. For example, the volume (sound volume) is varied and output according to the magnitude of the acceleration α.

(G-2) Vibrator Further, the game controller 1300 may incorporate a vibrator. The vibrator may be vibrated with a vibration pattern corresponding to the magnitude of the acceleration α detected from the acceleration sensor 1306. In this case, for example, a vibration pattern in which the number and interval of vibrations are gradually changed according to the magnitude of the acceleration α is used.

(H) Warning When the game controller 1300 is shaken too much, a warning may be given. Specifically, when the magnitude of the acceleration α detected by the acceleration sensor 1306 is equal to or greater than a predetermined magnitude (threshold), a message indicating that the swing is too strong is displayed on the display 1202. Further, a predetermined warning sound for notifying the player that the swing is too strong may be output from the built-in speaker, or the built-in vibrator is vibrated with a predetermined vibration pattern for warning. May be.

(I) Type of game Moreover, although the above-mentioned embodiment demonstrated the case where it applied to the fighting fighting game, it is applicable also to another game. In other games, the present invention is applied not to weapons but to various instruments used by the player character.
