This will duplicate a given room and return the duplicates index to be used in all further calls to reference the new room.NOTE: New rooms are not part of usual room ordering, so they do not have a "previous" or "next" room (meaning that the functions room_next and room_previous will not work). To jump from the added room to another, you must use the index of the room itself.IMPORTANT! This function is not available with the Trial Licence of the product.
Argument Description index The index of the original room to be duplicated.
global.myroom = room_duplicate(rm_level);
This will duplicate the room indexed by "rm_level" and assign the room index of this new room to the variable "global.myroom".
