Usage: gms_init ( controller_object )
This function only needs to be called when using one of the GameMaker: Studio versions of GameMaker Server.
This function initializes the extension. This function must always be called before any other GameMaker Server function.
If an error says the variable global.__set is not initialized, this function was not called on time.
controller_object should be the object from which gms_init, gms_step, gms_draw and if needed gms_network are executed.
