tilemap_tileset

Using this function you can change the tile set resource assigned to a given tile map element on a layer. You give the tile map element ID (which you get when you create a tile map element using layer_tilemap_create() or when you use the function layer_tilemap_get_id()), and then supply a tile set index and the tile map will be given the new sprite.

 

Syntax:

tilemap_tileset(tilemap_element_id, tileset_index)

Argument Description
tilemap_element_id The unique ID value of the tile map element to change
tileset_index The new tile set index to use

 

Returns:

N/A

 

Example:

var lay_id = layer_get_id("Tiles_trees");
var tile_id = layer_tilemap_get_id(lay_id);
if tilemap_get_tileset(tile_id) != ts_Nighttime
    {
    tilemap_tileset(tile_id, ts_Nighttime);
    }

The above code checks the current tile set assigned to the tile map on the layer "Tiles_trees" and if it is not "ts_Nighttime" then that tile set is assigned to the tile map.
