I need some help eventing a challenge I'm making. Because of the way it works, one level has a room that will only work right if there is no more than 1 person inside at a time. I need a way to event it so that when a 2nd person comes in, they are pushed out, teleported, whatever. And when the first person leaves, the 2nd person can then come in. I tried using zone events, but the zone wouldn't change size the way I wanted it to. It needs to cover a room that's 28x52x10.
