I am creating a top down 2D Game. The Game will mostly consist of a Player and Several TileMaps (each TileMap representing a different floor of a house). The Player will use "Stairs" to move between floors. Right now I am hiding all the floors the Player isn't on and showing the floor they are on. The Problem I am running into is that the collisions on the hidden floors are still active, meaning if I have a wall on floor one, when the player is on floor 2 they still are unable to cross where the wall is on the hidden floor 1. How can i "turn off" the hidden floors so the collisions are no longer active. Any help someone could offer would be great. I am kind of new to all this so bear with me.
