Returns: N/A


With this function you can set a background for a room (except the current one), with all the same property options that you can find in the room editor like horizontal speed and horizontal or vertical tiling.


global.rm = room_add();
room_set_background(global.rm, 0, 1, 0, bck_Space, 32, 32, 1, 1, 4, 0, 0.8);

The above code will add a new room to the game and then set the background of that room to the background indexed as "bck_Space" and set the properties for that background.
