857 857 * Tue Dec 19 15:34:00 CET 2006 elmex: changed the function to ignore op
858 * because the check-inventory semantic essentially only applies when
859 * something is above the inventory checker.
860 * The semantic prior this change was: trigger if something has moved on or off
861 * and has a matching item. Imagine what happens if someone steps on the inventory
862 * checker with a matching item, has it, activates the connection, throws the item
863 * away, and then leaves the inventory checker. That would've caused an always-enabled
864 * state in the inventory checker. This won't happen anymore now.
865 *
866 * Wed Jan 10 11:34:26 CET 2007 elmex: fixed this function, we now check
867 * whether op is on this mapspace or not, because the value (1|0) depends
868 * on this information. also make sure to only push_button if op has
869 * a matching item (because when we do a push_button with value=0 timed gates
870 * will still open)! (i hope i got the semantics right this time)
