Ok, I'm not near my computer, so I can only theorize, but if I set the func_door to -1 tim to re-open, then it will be stuck on closed.
BUT - if I can re-trigger that (heard you could do that) like 2 seconds later, then will it open again? Maybe have to set a toggle flag?
Even my entity guide is not at work with me...
Oooops.... Wasn't supposed to know I frequent the mapping forums at work.
