So I am working on a map that should have a one way door, kind of like the one way doors that can be found on Dustbowl. However the door can be activated from both sides, even if I do scoot the trigger_multiple and the func_door waay back away from said door. Is there any way of doing this? I looked at the cp_dustbowl map to see how Valve did it, however they (somehow) did the same thing and used a trigger_multiple hooked with a func_door to control the door prop. But yet somehow the door is still only one way.
