Player to Integer - slimy_asparagus - 12-02-2020
What is the cleanest way to convert a player to an integer?
I would have the cleanest would be (id "P1") or (id "P2") but I cannot get it to work. I am trying (in a different game) to do something like:
Code:
(piece Foreground "Square" state:(id "P1") image:"disc" fillColour:(colour Black) scale:0.4)
(piece Foreground "Square" state:(id "P2") image:"cross" fillColour:(colour Black) scale:0.4)In a related question, are we forced to identify a player with a colour? A few games resist that and use symbology instead.

Hi,
Just with (id P1).
P1 to P16, Neutral, Shared, All, Mover, Next, Prev, etc... are RoleType and can all be converted to their index value with (id ...).

Eric

Thanks for looking. I cannot remember whether I tried that particular formulation. I can now see that it is what the documentation would imply. However when I try I get a non-specific compile error. I attach the file I was working on (which is pretty simple).

Hi,
Oh, be careful, you are using some IntFunction ludemes in the metadata. The metadata are not part of the logic. Only simple integers can be used in them. You should be able to check that in the LLR. So the ludeme (id ...) which is an IntFunction can not be used in the metadata.
Except the LLR, no guide exists about the metadata, we are discussed about writing one in the future, but that's not sure and not a priority for the moment.

However just out of curiosity I did wonder if that would be the answer and I tried an experiment. The attached test.lud still fails to compile. Fixing it is of no concern to me, but from what you are saying it seems it ought to compile so I am puzzled.

Hi,
Same thing for the starting rules, they are not using the IntFunctions. These functions, in general, needs a state to be run, however, the starting rules are building the initial state. So in general the functions are not possible in them.
You can look that in the LLR, but as a general rule no function inside the graphFunctions (building the board, so the initial state), the starting rules or the metadata.
