RakNet

I need help using this in a game. All I need to do is update the player location (x,y,z) rotation (y), and a type that will I can broadcast chat with? Please help. I'd perfer code examples, but beggers can't be choosers.

KuRiX released a wrapper in the userlib forum. There's an example inside, you can mod it easily to send locations, instead of the "hello" thing. It's really worth to study this little source.

Yes, take a look in the userlib forums and if you need any help please post your questions in the raknet wrapper thread and i will answer as soon as possible.

Cheers.
