Hi Uniteers, I have made quiet the research on network code but I still feel I have a few unanswered questions I need answered before I feel comfortable diving into developing a networked game using an authorative server. Imagine an ordinary FPS game such as counter-strike: Is collision detection handled on server side in order to prevent players from moving out of bounds and run in between walls? If collision detection is handled on server side would you run an Unity instance on a server in order to be able to do the necessary raycasts? If not, what is the alternative? If you were to run an Unity instance on a server, how would you do that? Would you run the instance in batch mode?
