* checker with a matching item, has it, activates the connection, throws the item |

* state in the inventory checker. This won't happen anymore now. |

* Wed Jan 10 11:34:26 CET 2007 elmex: fixed this function, we now check |
897 |
* whether op is on this mapspace or not, because the value (1|0) depends |
898 |
* on this information. also make sure to only push_button if op has |
899 |
* a matching item (because when we do a push_button with value=0 timed gates |
