I've got them working perfectly so that when you come in it's closed, and when you solve the puzzle it will open. however, if you come back in though the shutter door, you can't get through because it's still closed.
I know you can probably solve this with Combo cycling, but is there any easier/more convienient way to do it?
Place a "trigger temp" underneath the top part of the door, (The overhead combo) <- You will need to use layers then. Then when you play the quest and come back through to the other side of the shutter, the shutter will open for the player to contnue through
Ah. I see...
...but then what do I do if there's more than one shutter in the room, and I want you to have to re-do the puzzle to open the other one?
