Hi
I'm writing a .zrf for Chess of the Four Seasons
(a Spanish four player variant), and I'm having trouble having Zillions convert all enemy pieces of a certain color to friendly pieces after capturing their king.
The problem is when I capture green or black's King it converts their pieces AND yellow's. The other problem is when I capture yellow's king no pieces are converted.
Here is an example of the macros I'm using:
(define flip-all
a1 (if $1 change-owner (set-attribute $1 false) (set-attribute $2 true))
(while (on-board? next) next
(if $1 change-owner (set-attribute $1 false) (set-attribute $2 true))
)
)
(define addd
(if (not-piece? King) add
else
mark
(if (in-zone? Play-zone Red-pos)
(if green? Green-pos capture (flip-all green? red?))
(if black? Black-pos capture (flip-all black? red?))
(if yellow? Yellow-pos capture (flip-all yellow? red?))
))
I would greatly appreciate some help with this. |

Try nesting your [color]? tests as follows:
(if green? Green-pos capture (flip-all green? red?) else
(if black? Black-pos capture (flip-all black? red?) else
(if yellow? Yellow-pos capture (flip-all yellow? red?))))
Under the current macro, it appears that if a green or black King is captured the flip-all macro stops scanning on a square other than the marked square (presumably the upper right square). If this position contains a yellow piece, then the yellow? test returns true and yellow pieces are flipped as well.
This wouldn't explain why the yellow pieces aren't converted when the yellow King is captured. |
