@eswenson1 is our Muddle and Zork expert. What do you think?

@AlexProudfoot Can you explain why adding the "DWIND" ID to the DWINDOW object is going to fix the issue? I don't see any reference to "DWIND" in the code. Only to the existing ID, "WINDO". I would think there would need to be a reference to "DWIND" somewhere in the code in order for this to have any meaningful effect.

As I understand it, although I’m by no means an expert, the identifiers in question are loaded into the parser’s vocabulary table when the game starts and matched (or not) to the player’s commands so I would not expect to see references elsewhere in the source code.

I believe “WINDO” is elsewhere in the source code because there is at least one other window (the kitchen window) in the game.

It’s not that heasm66/mdlzork#30 is going to fix the problem. It has fixed the problem.

The solution is based on the CPWALL objects, each of which has a unique first noun entry. I reasoned that if DWINDOW had the same kind of definition, it might fix the problem.

Why this works in Confusion but not in Muddle eludes me.

There are references to “WINDO” in the code, but none to “DWIND”. For your change to the object to have any effect, you’d need to have some other code reference “DWIND”. Does your code reference “DWIND” anywhere?

I don’t see why anyone would ever type “dwind”, or a word with that prefix to the parser? In any case, how would it fix anything?

With respect, as I explained, the change does have the desired effect when using Confusion. The nouns “DWIND” and “WINDO” don’t have to be referenced elsewhere in the code.

I think (that is I’m not certain since I’m no expert) that each object must have a unique list of nouns. The point of “DWIND” is to provide a unique list of nouns, not to allow the player to type commands like “look at dwind”.

Ok. I’ll take your word for it. I’ll apply the fix and debug the original problem if it still occurs.

Ok Eric. Good luck.

Here is the output from the Confusion patched version of Zork after fixing the "WINDO" GOBJECT.
