TCP/IP vs. UDP (sort of one sided, but I promised this thread)

Here''s the situation. You have a game that you need networked. It will be a fairly high speed, 2D space shooter. There will be a central server for a lobby, and the game needs to be networked. The program parameters are as follows. All shots travel in a straight line after being fired. Player cannot stop on a dime, so normal physics of motion apply. World coordinates are measured with FP numbers, using X and Y planes only. Z plane is not used. Players must be allowed to join or leave the game at any time. Should be scalable to dozens of players. It is meant to be played over the internet, so internet latencies and lag apply. What is the best way to do it? The lobby server is a required component to find the game, so that can''t be cut out. Continued communication with the lobby server is not required, but it must know when people enter and leave the game. Post your questions about the problem and possible solutions with pros and cons here. You should also comment on how the game should handle dropped packets, dead reckoning, latencies, etc, distorting the game as little as possible. Discuss and be happy. Otherwise, continue the flame war from that *other* thread. Looking for an honest video game publisher? Visit www.gamethoughts.com

Pro UDP
send the last second of the directx 9 user input buffer
repeat this every 50ms, so you have overlapp (security).
lag>1sec , even occasionally is to much, kill this player

No it''s not. I used to play Asheron''s Call with ~1s lag. I live in Australia, and at the time, I only have a 56K connection. It was still playable, though rather laggy (but not detrementally so - sometimes I''d click on a monster, but someone had already killed it, etc).

If you work your game mechanics right, large amounts of lag shouldn''t be that big a deal.

If I had my way, I''d have all of you shot!

Player will shoot each other,
so lag is worse here than when clicking on a monster
