I've been working on "Arena", my new game, for about a week now and have been working up to getting this bad-boy online. First a little background I suppose, since original posts were on another forum. At it's most basic level, this is a side-scrolling, two-dimensional, four player online fighter. The premise is that you just fly around on jetpacks (or walk) and shoot each other. Currently, gameplay is pretty bland, but eventually I'm going to add content. Basically, I'm just getting a framework to build on for now. So, to the topic. I'm using RakNet for networking and I'm a little confused with the logistics of moving necessary data around on the network. Lets say for argument that Player1 are only sending their (X,Y) coordinates to the server for distribution to the other three players. Ok so the server will get a CLIENT_POSITION_UPDATE message or something to that accord and then send out a SERVER_POSITION_UPDATE message to the other three clients. Ok, so how will the clients that receive this message discern between which message goes to what player and draw accordingly. As you can see, that last paragraph was very unclear... I think that shows exactly where I'm at in my thoughts right now so any help is appreciated. If you want to check out where I'm at thus far, you can check out this clicky: Clicky! All the art and such was done by me, I'm proud since I can barely draw on computer =P toXic~

I guess one way would be to just include the Id of each player (1-4) in each position update packet.
