Hi, I have a this sliding door that works like a lift door (i.e. it slides sideways concentrically). The game allows me to place the door right in the corner if I want to, but I would like to modify the object so that the game doesn't allow me to place it right in the corner. That is, I'd like it to only allow me to place it 1 tile away from the corner, and for the footprint to be red when I try to place it in the corner. I've tried modifying the footprints and measurements in boundingbox, but it still allows me to put the door right in the corner. Does anyone know how to force this?

This is what I want.


This is what I don't want.

So... nobody has a clue?
