tilemap_set_width

Description

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.


Syntax:

tilemap_set_width(tilemap_element_id, width)


Arguments:

Argument Description
tilemap_element_id The unique ID value of the tilemap element to set the width of
width The width value (in "cells")


Returns:

N/A


Example:

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.
