Update: I’m trying to make a flexible script for travelling through different scenes. There are 4 rooms (A,B,C,D) and 3 doors. If someone more experienced in Python could look it over, I’d appreciate any suggestions. I can post a more detailed description of how the system is supposed to work if necessary.

You start out in RoomA, looking at the door to roomB. If you turn round and jump up, you will see the door to room C. Each door has a corresponding empty that sets the position of the player if you enter through it.
