Hiya, lurker here looking for some advice. I am making trapdoors in my TF2 map, and I want them to be shootable from below by other players, thus making them open. I successfully made the trapdoor and it opens correctly, but I'm at a loss to what kind of trigger to put underneath. I couldn't use a func_breakable, since I want the door to reset itself after a few seconds and be shootable again. What to do?
