I'm trying to create an old-school 16bit RPG town. I've designed a Tileset and have used it to draw a town area in a Tilemap. However, I'm finding that I want to override the collision I've set up in a lot of cases. For example, for wall tiles I generally want the player to be able to walk behind the top part of the wall but not the bottom part, so it would be nice if I could manually set the collision for only some of the tiles.
Is there a way to do this?
