Re: Raycasting problem
Author: jakub.gemrot
Hi!
Unfortunately its working flawlessly for me. So I expect there would be some configuration problem between your version of UT2004 and GB2004 and mine.
1) do you have UT2004 patched? (part of the official pogamut installer)
2) do you have latest version of GB2004? (I know I've asked, but it worth a shot try to reinstall JUST UT2004Patch + GameBots2004 from the latest Pogamut 3.3.1 installer)
3) did you alter GameBots2004.ini in any way?
Just to be sure, I'm copy pasting a code I'm running here + copy pasting my GameBots2004.ini
