Once you get the jest of it you'll see it's easy. I made a quick simple test map, all stock, only one custom script is needed.
Play passes thru "trigger1" by door, goes down hall thru "trigger2", goes back to door thru "trigger1" which in turn opens door.
If you look at the setup you'll notice... "Trigger1" does NOT "Activate" until player reaches "Trigger2". (look at the "activateifused" field for each trigger)
"Trigger2" activates "Trigger1", "Trigger1" activates "Remote Door"
My games never have bugs. They just develop random features..
Lots and lots of random features...
