I worked with protobuf in c++ a few years ago, and recently succeeded in getting protobuf-c to work. I've only just started looking into the server/client messaging side of quake source, but I'm already wondering could this code be cleaned up, simplified and made more flexible with protobuf? 

Started learning QuakeC a couple days ago, and have been doing pretty simple stuff just to get the hang of things. When I say simple things, I mean VERY simple stuff like:

if(self.key_bind4 == TRUE)
{
self.walkframe = 109; //play an animation from the mdl
}

I wanted to know if there was some way for me to add a damaging hitbox to the player when they hit this button and the animation plays. An example would be an animation of the player swinging a bat or something, and a hitbox being created where the bat physically is. I'd appreciate any help!
