* Wed Jan 10 11:34:26 CET 2007 elmex: fixed this function, we now check |
893 |
* whether op is on this mapspace or not, because the value (1|0) depends |
894 |
* on this information. also make sure to only push_button if op has |
895 |
* a matching item (because when we do a push_button with value=0 timed gates |
