Each connected player has a corresponding client object. It has variables and procedures which control aspects of player input/output. This object is also responsible for linking the player up to a mob.
The client can be reassigned from its original mob M to a new mob N by setting N.client = M.client. This process disconnects the player from M (calling M.Logout()) and connects the player to N (calling N.Login()). Setting the mob’s key has the same effect.
Additional vars, procs, and verbs may be added to the client in order to give the player properties that are independent of the mob.
