: Thanks, yeah! I did think of that because I know you can change the starting
: state of those items but if I'm doing doors people will most likely be in
: the vicinity of the spawning object... :/ I tried something complex with
: timers and single on and off switches but... nothing so far.

What exactly isn't working? Do note that objects will not spawn/despawn via scripting in forge. In order to see this work, you need to exit forge and load the map in a custom game.
