tilemap_get_tile_width

Using this function you can retrieve the width (in pixels) of each tile cell of the tile map element.

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 the function will return the tile set cell width.

Syntax:

tilemap_get_tile_width(tilemap_element_id)

Returns:

Real

Example:

var lay_id = layer_get_id("Tiles_Walls");
var map_id = layer_tilemap_get_id(lay_id);
global.snap_x = tilemap_get_tile_width(map_id);
global.snap_y = tilemap_get_tile_height(map_id);

The above code uses the retrieved tile map ID to get the tile cell width and height and use them to set two global variables.
