I made a procedurally generated backrooms game, right now it’s only a walking sim, but I will add more things in the future, possibly more levels or some survival mechanic.
What the modes do:
Normal Mode - Normal map creation, 33% chance for a tile to be a wall
Open - A more open map, 25% chance for a tile to be a wall
The backrooms movie is going to spawn so many new backrooms games! If you wanna make it infinite, you could try shifting the tilemap around as the player walks to generate more terrain! I’ve done something like that before for a 2D game so it should translate to 3D and would be quite cool.
You wouldn’t need that. You spawn the player in the center of a map and every time they get close to an edge you copy the tilemap around them, place it all into the center of an empty tilemap, and randomize the rest of the area.
