I am getting an error related to my not-in-zone? check. Could someone tell me what i am doing wrong.
(define slide-jump ($1 ( while empty? $1) $1 ( verify not-friend?)( verify not-in-zone? my-zone ) add))
I need the piece to never end it's move in the zone.
Thanks in advance. Dralius |

Try an extra set of parentheses around (not-in-zone? my-zone), so that the test becomes: (verify (not-in-zone? my-zone)). Basically Zillions requires any ? test that takes an argument to be set off in parentheses. |

Two other problems, I think.
First, the syntax for while is:
(while condition instruction ... instruction)
In your code, the while statement does not have any "add" instruction inside it, so I think at best your code will generate only one possible move.
Second, I assume you may want your piece to be able to slide through the named zone, a long as it doesn't stop within the zone. In that case, you don't want to use verify, which shuts down the move block as soon as it evaluates to false; use an "if" statement there instead.
I think this may be what you want:
(define slide
($1
(while empty?
(if (not-in-zone? my-zone) add)
$1
)
)
(verify not-friend?)
(verify (not-in-zone? my-zone))
add
) |

Dear Dan & Don
Thank you for your quick reply. The problem was with the parenthesis.
To Dan thank you for helping me understand the script syntax.
To Don i appreciate you showing me and others who are novices how to construct a proper move definition. Altho i will not need it for this game i have added it to my reference book.
Credit will be listed in the .zrf as i hope to post the game once i have the graphics completed. |
