My walls are passable...

I imported the only hospital tileset that seems to exist and the only problem with it is that even though the walls in it are set to impassable you can walk all over it and a few other pieces as well. Anyone have a solution to this?

Um, maybe. Is it possible that you ran over one of the upper layers with a transparent tile that isn't the upper left tile in the tileset? If so, that could cause the error. Try running over all of the transparent tiles in the second and third layer of the map with the upper left tile in the tileset and see if that fixes it.

Nah that didn't work. Thank you though.

OK, what about the priority of the upper left transparent tile? Is it set to *5? It should be.

That was it! Thank you so much!

Glad I could help
