描述

With this function you can set the cross origin type to use when loading images from a file. The function is exclusively for the HTML5 platform and is only useful when loading sprites from a file using the sprite_add function. Note that when set to "use-credentials" you no longer need to give an absolute path to the sprite being loaded, but instead would give a relative path (as shown in the example below). By default the cross origin type is set to "anonymous".

语法：

http_set_request_crossorigin(origin_type);

参数	描述
origin_type	The cross origin type to use (a string)

返回：

N/A（无返回值）

例如：

if string_lower(http_get_request_crossorigin()) != "use-credentials"
    {
    http_set_request_crossorigin("use-credentials");
    }
sprite_add("sprites/player_outfit_1.png", 0, false, false, 0, 0);

The above code will first check the currently set cross origin type and if it is not "use-credentials" then it is set to "use-credentials" and then a sprite is added from a file.
