mset
mset(x, y, tile_id)
- x, y : map coordinates.
- tile_id : tile index (0-255).
This function writes the specified background tile tile_id into the map at the given position. By default, changes to the map are lost when execution ends but they can be made permanent using sync.
The map coordinates are not to be confused with the screen coordinates. One screen can contain 30×17 cells.
