I want to add networking to my game. However, it''s not my primary focus, so I don''t want it to impede the development of the rest of my game. With the vast increase in broadband technologies, I''d rather sacrifice some, or hell, a lot, of network efficiency to have a clean and extensible model. Which I guess means moving towards more of a dumb-terminal approach. And that''s my problem. How do I do that? And how far can I take it practically? I know how Quake etc does things. I also know it has a lot of retraints and complications, a lot of stuff has to be hard-coded and it limits what can be done in single-player. Carmack mentioned this and how he plans to compromise network efficiency (no 56kers) in Doom 3 to simplify the networking model. I figure that the game has to be divided into events and state. For example, a particle effect could be an event, a sound would be an event, entities positions would be part of their state. I already see a problem here. I''d need to explictly code for all the events in my network model, which complicates dependencies. And state updates would need to identify what types of objects are being serialized, which implies some kind of run-time type-identification - even more complications and dependencies to my nice clean single-player game model! Are there any good answers to this question, or will I need a hodge-podge mix of the above. All I want to do is find a clean simple extensible solution to networking to my game.
