I'm working on a 3d multiplayer game. Initially its basically gonna have the functionality of a 3d chat room with avatars and such.(There will be no collisions between avatars, so the main goal is how movement of other people look)
My question is this:
What are some of the prefered options to handle updating of position?
We will have a client server setup, with multiple clients connected to our server. We have discussed trying to impliment a UDP Multicasting system, and have also debated a TCP/IP system. Is it possible to do a UDP Multicast with an internet based game?(Meaning computers not on same subnet and such) We are trying to avoid TCP/IP because of its huge network loads. Please give me some thoughts, and your reasoning! Just looking for a proof of concept, no code really.
