Quake3World

Quake3, as far as I can tell, has animation states for both the torso and the legs, but what I'm not really sure about is how this information gets passed to other clients - obviously it's through the network - but can anyone tell me what mechanism?

I've done work with the modelling and rendering and want to 'kick it up a notch.'

It's sent via every player's associated playerState_t structure and processed in bg_pmove.c (look out for functions like PM_StartTorsoAnim and PM_StartLegsAnim).
