I just wanted to say this because it was something that I had a lot of trouble with. When creating a door that is animated (most usually the type with the small pulley system to the side that spins when the door is opened). So what I did was create the door normally, then edited the outputs on the func_door so that OnOpen it would set animation open and OnClose it would set animation close (for detail look at the spawnroom tutorial in the tutorials section). However, I was extremely agitated when the whole door frame, pulley system included, moved up and disappeared :cursing: The simple solution to this is to make sure that the func_door is not a parent of the prop_dynamic. Just wanted to post this in case anybody else had the same problem, because it was extremely frustrating for me.
