That 3d thing

[Marcus]

Just put a dragon and it's already a Dungeon and a Dragon game 
I saw that using s3d, it's possible to have different floor and ceiling texture depending on the room's theme. For example : King's bedroom has red floor and red ceiling, Ballroom has golden floor and golden ceiling, Kitchen has green floor and green ceiling etc 
..... Back to wolf3d, is it possible to have that kind of different floor and ceiling texture depending on each theme ? How to do it if it's possible ?  (sorry it's an out-of-topic question) ...

In the engine and editor that i'm writing you can set a wall, floor and ceiling texture per sector (room). But you can also set individual textures per wall in the sector if you want.

I see that you currently use SetFloorTexture and SetCeilingTexture. They change the texture for all floor/ceiling tiles. You can use SetFloorTextureAt(tile_x, tile_z, img) and SetCeilingTextureAt(tile_x, tile_z, img) to change the floor/ceiling for individual tiles.

You can also use SetNorthWall(tile_x, tile_z, img), SetSouthWall(tile_x, tile_z, img), SetWestWall(tile_x, tile_z, img) and SetEastWall(tile_x, tile_z, img) to set textures for the individual wall sides of a tile.
