Are you going to dive in as how you managed to attack the update freeze when tinkering with the windows? Curious as hell…

Hi Andrew: I have been watching your videos especially for networking physics simulations and they are very informative. I wanted your thoughts on a game I am developing. I am working on a soccer game (only 2 players play a match). I don’t have an authoritative server so to speak so the game is essentially P2P, however each player connects to a “dumb server” which works as a matchmaking server as well as “message router”, both players send messages to the central server and the server re-routes messages to the peers. This a generic service that I am using so I don’t have to maintain a server myself and it helps with NAT/Firewall stuff as peers are not connecting to each other directly. depending on where the peers actually are, message transmission from one peer to another may take anything between 100 to 500 milliseconds. So with this situation, what would you recommend as a good approach for networking the physics and gamestate. I started with a basic implementation, both peers are running physics and game logic. Each peer is authoritative over his soccer team (5 players aside) and sends player velocities across as soon as velocity changes and positions across 5 times a second. player positions usually look OK on both peers in initial tests. But there are serious issues. a) game time is not synced across peers, peer 1 action takes place immediately on peer 1 but arrives X milliseconds later on peer 2 b) no peer is authoritative over the ball so no sync in place for that. even if I use strategy like peer1 is authoritative over ball if peer1 is in control of the ball and vice versa, it still leads to issues.. who is authoritative when the ball is in flight, no peer is controlling it. and peer1 stealing ball from peer2 becomes impossible as peer1 action is delayed on peer2. also there is the matter of goal scored. peer1 kicked ball, peer2 got message late and applied kick, peer2 goalie took defensive action and saved the goal but peer2 goalie action took time to reach peer1, by then goal was already scored in peer 1 simulation. Any comments on this will be highly appreciated. I am noob so please pardon my ignorance. I read up a lot on prediction/lag compensation etc but all those discussions depend on ONE authoritative server. I also thought about running the game simulation on a separate thread 400 milliseconds ahead of rendering thread but want to get your expert thoughts on this. 🙂
