I'm sure there are many ways to make these. I've been suggested to use trigger push and func_conveyor with a func_door_rotating (if you want it to look like a catapult) I was also directed to a prefab on FPSBanana that was a conveyor type launcher. Here I'd like to discuss what do you think the best way to make a player launcher would be? Using push or conveyor? Or is there something else that could make it work? I would think a simple design would work best, and I am frustrated there is no "Force Open" for rotating doors. Why have force close without the other? I've also thought of possibly parenting something to a func_door_rotating to make it push you.
