I've noticed in CrazyBob's Cops and Robbers. He has made it so the class selection list can vary depending on the player. For example if a player is already registered and he enters the server, the only class in the class list is the one he had orginally chosen when registered. How is it possible to do this? Doesn't AddPlayerClass works as a function globally to all players? How can it show only specific classes for specific players?
