Hey there, does anyone know if there are any open source action/realtime games out there which feature multiplayer or are based on multiplayer? I've been trying to get information on that particular matter for more than a week, but all I can get are very wishywashy general descriptions of how client/server models work, what TCP/UDP is, all that basic stuff which doesn't cover the actual problems. And there sure as hell aren't any tutorials for that kind of network architecture. (I'd love to be proven wrong here. Also I'd like to make a few myself as soon as I get the hang of it)
Anyway, It would be great if I could study some actual code, I don't even care what the language is anymore, If I can't read it I will just have to make the effort of learning it to be able to understand the networking logic. Btw, I think this doesn't really matter that much, but I'm aiming for a 2D game here.
You may be interested in Bungie's GDC presentation on networking in Halo: Reach (slides available here). Some of the stuff they go over is more valuable than just raw source code, in my opinion. They don't talk about how to get the sockets set up, etc. Rather, they focus on issues that come up in networking and how to overcome them, which is a critical aspect of networking, and something that isn't explained in code.
