868 * The semantic prior this change was: trigger if something has moved on or off

870 * checker with a matching item, has it, activates the connection, throws the item
871 * away, and then leaves the inventory checker. That would've caused an always-enabled
872 * state in the inventory checker. This won't happen anymore now.

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