Basically, what I want is this. I have a trigger_push that pushes people through and out a door. However, I only want the trigger_push to be active shortly before and after the door is open. So it goes like this: Player reaches a certain point trigger_push activates, pushing the player towards the door Door opens, player is pushed through trigger_push pushes them away from the door Door closes, trigger push is deactivated. I have no idea how to go about setting up the entities to do this. Any help is appreciated.
