First of all, I really appreciate all your help. I'm starting to get things the way I want them to function. I'm sure any experienced coder would gasp if they ever saw how I have done things but no matter. Next I want to fix the flashlight in 3rd person so the projected texture is coming from the player instead of the screen. Do I need to edit the vertex shader code to do this? BaseVSShader.cpp? I suppose it would be sufficient to just attach the env_projectedtexture to the muzzle of the player's gun perhaps. > On Mon, Jun 1, 2009 at 1:16 AM, Chris Marshall <[email protected]> > wrote: > > > First of all, what is the difference between CAM_Think() and > > CAM_ThirdThink()?
