This function can be used to resize a tilemap element. You give the tilemap element ID (which you get when you create a tilemap element using layer_tilemap_create() or when you use the function layer_tilemap_get_id()), and the new width of the tilemap in tile cells.
tilemap_set_width(tilemap_element_id, width)
| Argument | Description |
|---|---|
| tilemap_element_id | The unique ID value of the tilemap element to set the width of |
| width | The width value (in "cells") |
N/A
var lay_id = layer_get_id("Tiles_Walls");
var map_id = layer_tilemap_get_id(lay_id);
if tilemap_get_width(map_id) != room_width div 16
{
tilemap_set_width(map_id, room_width div
16);
}
The above code checks the width of a specific tilemap and if it is not the correct size then the width is set.
