-- [ Picked text/plain from multipart/alternative ] In simplest description, All tracelines do is move a virtual 'point' object through space checking collisions. A tracehull does exactly the same thing except the virtual 'object' isn't just a point, it's got bounds. I'm not 100% certain how much source's traces are still like quake / hl1, but i'm pretty sure the base is the same; with a bunch of new stuff and optimizations. -Tony
