I've already downloaded the MMO and FPS examples and tested them for a little bit. Everything seemed understandable to me, but until I wanted to add a simple Health Variable and attach it to the player. As I can see in FPS example, all player variables are made on a server side by CombatPlayer "simulation", but in MMO example such variables as material, model, location coordinates of player are containing on the client, if I understood everything correctly. As I suggested, it is because MMO example uses the AOI system, but I might be wrong.
So my question is: How to correctly add a variables such as mana and hp to player for a MMORPG?
