|index||The index of the tile to set.|
|background||The index of the background to take the tile from.|
With this function you can change the background image asset
that the tile is taken from (maintaining the tile in the room, at
the same position but with a different graphic). This is not
permanent and if the player leaves the room and returns to it
again, the tile will use the original background again (if it was
placed in the room editor and the room is not persistent).
tile = tile_layer_find(-1000, mouse_x, mouse_y);
if tile_exists(tile) tile_set_background(tile, bck_Forest);
The above code will check for a press of the left mouse button, and then check the mouse position for a tile. If there is one found, that tile has its background asset changed.
