Doors that only open from one side.

[Besley xD]

Hey,
I was wondering how to make doors that only open from one side, like the one on Dustbowl stage 2 cap 2,
If anyone could help i will be very grateful

Thanks

Just like doors that open both ways, just make sure the trigger is only on the openable side.

Also, make sure to uncheck the "Touch Opens" flag on the func_door.
