|ind||The index of the original room to be duplicated.|
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.
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".
