You have to distinguish between identity and state.
Disclaimer: I have no clue whatsoever about game design.
The different rooms are identities, the different players are
identities. An identity might have a varying state over time. So the
right thing to call for are Clojure's state handling facilities, eg.
Refs.
(declare player1 ork *room1* *room2*)
(def player1 (ref {:in-room *room1* :inventory nil}))
(def ork (ref {:in-room *room2* :health 100}))
(def *room1* (ref {:occupants #{player1}}))
(def *room2* (ref {:occupants #{ork}}))
Now time evolves and the player in front of the keyboard goes south:
(dosync
(alter player1 assoc :in-room *room2*)
(alter *room1* update-in [:occupants] disj player1)
(alter *room2* update-in [:occupants] conj player1))
Now the refs look like this:
player1 (ref {:in-room *room2* :inventory nil})
ork (ref {:in-room *room2* :health 100})
*room1* (ref {:occupants #{}})
*room2* (ref {:occupants #{player1 ork}})
The STM takes care to coordinate these changes also across different
threads.
You might want to explore http://clojure.org and watch some of Rich's
screencasts.
Hope this helps to get you started.
Sincerely
Meikel
