Jump line of pieces as long as at least one piece of type is present - AlexanderBrady - 02-23-2023
I am trying to create a code where piece A can jump a line of pieces of types A, B, or C, but only if at least one C is present in the line. Is this possible?
Here is the code I have written, but it only allows A to jump if all pieces in the line are C.
Code:
(move Hop
(between
(max (count Rows))
if:(and (or {
(is Empty (between))
("IsPieceAt" "Soldier" Mover (between))
("IsPieceAt" "Shooter" Mover (between))
("IsPieceAt" "Base" Mover (between))
} )
(>= (count Pieces Mover if:("IsPieceAt" "Base" Mover (between))) 1)
)
)
(to if:(is Empty (to)))
(then (promote (last To) (piece "Shooter") Mover))

Do you have a .lud file?, maybe someone can help then.
and
Did you check with the 'Test Ludeme' dialog what the (count Pieces) line really creates as result in various cases?

Here is a pastebin with the ludii file:

Ignore the metadata, which is just copied from the Chess Ludeme.
I haven't tried the "Test Ludeme" dialog. I did some testing with the code that I have - it seems to count each "between" space individually.
If I set the minimum count to 0, the "if" statement does nothing (which makes sense). If I set it to 1, it works if and only if every "between" space is the target piece type (not a minimum of 1 of that piece, every "between" space is that piece). If I set it to 2 or more, the movement option is never allowed.

Ok, I had a look at it but the (ahead (from) #1 (directions .. ) line did not compile in my Ludi.player 1.3.10.
