Making an escape/infiltrate map series, so far it's pretty good. You can tell it's amueter and not professional but I think most people here would play it.
The problem is, to add feeling that you're escaping a secure facility, the exit is a double blast door, and the lights and siren activate when it is either a) in motion or b) open.
Right now I set the door's target as "securedooropening1", and it only activates when the door is open. Is there a way to make it activate while the doors are ONLY moving, like in the Half-Life series when you should shoot the buttons and the blast doors would close?
