I am trying to create a network game server based on Chipmunk. I have read the classic "Fix your Timestep" article by Glenn Fiedler, and everything I can find on networked games.
I understand, that for networked games to play well, the server needs to have the ability to back a few timesteps, to replay events as new input comes from players.
Obviously, for that to work, I need to save Chipmunk world state from time to time. (At least 10 times per seconds.)
Is there some way to do that? This weekend I trawled the forums and found something about how state of objects can be read out, except for "impulses". (Whatever that is.)
