Adding Camtrace 3D support to your fav game! Here for example Wolfenstein Enemy Territory
Hello,
Basically this should be no problem at all if you have the Game Source code of the Game.
I will just paste my source i used for the uv-movieMod (worked for RTCW, ET, Q3 and basically also for QW)
What do we need?
getViewPos -> prints the current camera position
setViewPos -> sets the current camera position
freecam -> init the camera
thats basically all you need to play camtrace cams. I will not go into detail (for example how to add a new console command)
Console Command setViewPos aka freecamSetPos:
freecam -> start the freecam
getViewPos aka viewpos - Be sure to have the excat same syntax
Now we need to tell the engine to render the current campos and not the firstPerson pos: (cg_view -> CG_CalcViewValues)
you can ignore the pmove stuff here, but we had to port all that from the game to the client which is a bit more in to depth here.
Hope it helped

you can ignore the pmove stuff here, but we had to port all that from the game to the client which is a bit more in to depth here.
