CaveUT on Linux

News

5 April 2002: It has recently come to my attention that not only does Unreal Tournament exist for MacOS, but that Apple openly supports OpenGL as well. If someone out there is looking to port CaveUT to MacOS, please let me know. I'd love to help out in any way possible.

23 December 2002: CaveUT 1.2 is now available for Linux.

Setting Up Unreal Tournament

Install Unreal Tournament

• Download the Loki installer.
  Use ut-install-436.run.gz for normal, blue CD Unreal Tournament.
  Use ut-install-436-GOTY.run for the red, Game Of The Year Unreal Tournament.
• Mount Unreal Tournament CD
  

  mount /mnt/cdrom

• Run install script
  

  gunzip ut-install-436.run.gz

  sh ./ut-install-436.run

Install Libraries

• SDL-1.2.2-3
• SDL-devel-1.2.2-3
• SDL_net-1.2.2-1
• SDL_net-devel-1.2.2-1
• SDL_mixer-1.2.0-4
• SDL_mixer-devel-1.2.0-4
• SDL_image-1.2.0-3
• SDL_image-devel-1.2.0-3
• Mesa-3.4.2-7
• Mesa-devel-3.4.2-7
• mikmod-3.1.6-12

They're all available on the RedHat install media. You may not need them all, but it's easier to just install the whole mess than to realize later you need another and installing them incrementally.

You can also download them from here. Please don't, unless you can't find your install disks or can't connect to a RedHat mirror site.

To install on RedHat 7.2, use the rpm command:

rpm -Uvh *.rpm

Other linuxes will vary. Check your manual.

Get CaveUT For Linux

Download the tar file from here. Save it into your Unreal Tournament directory. Then simply untar it from within the directory:

tar xzf CaveUTLinux-1.2.tar.gz

Type make

NOTE: If you're not running RedHat 7.2, the precompiled SDLGLDrv.so library may or may not work for you. Delete it from the System directory to rebuild it, to make sure.

Do this from within your Unreal Tournament directory. This will build and install the CaveUT components, namely the updated GL driver and the CaveCalc utility program. Drop me a line if you get errors.

Edit View As You Wish

For background, see Jeff's page.

• Go to System directory.
  

  cd System

• Edit Cave.ini
  See Jeff's page.
• Run CaveCalc
  

  ./CaveCalc

• Copy Values Out of OpenGlDrv.ini
  Find the last 4 lines of each section. It will look like this:
  
  

  BottomScaleInt=100000
  TopScaleInt=44615
  RightScaleInt=72307
  LeftScaleInt=72307
  

  
  The numbers might vary. Copy these lines to the clipboard.
• Paste into UnrealTournament.ini
  Find the section labeled [SDLGLDrv.SDLGLRenderDevice]. After the last line, insert the four lines you copied from OpenGlDrv.ini. Save the file. When done, it will look something like this:
  
  

  [SDLGLDrv.SDLGLRenderDevice]
  UseGammaExtension=0
  UseModulatedGamma=0
  UseS3TC=0
  OpenGLLibName=libGL.so.1
  MinDepthBits=16
  MaxLogUOverV=8
  MaxLogVOverU=8
  UseMultiTexture=1
  UsePalette=1
  UseAlphaPalette=0
  ShareLists=0
  AlwaysMipmap=0
  DoPrecache=0
  Translucency=True
  VolumetricLighting=True
  ShinySurfaces=True
  Coronas=True
  HighDetailActors=True
  DetailTextures=True
  UseTrilinear=False
  BottomScaleInt=100000
  TopScaleInt=44615
  RightScaleInt=72307
  LeftScaleInt=72307
  

Run the Game!

As long as you installed the Unreal Tournament binaries to somewhere in your PATH, you should just be able to run it with

ut

Make sure you don't already have a preferences directory (~/.loki) or manually copy over the newer initilization files.

Tips and Tricks

Edit UnrealTournament.ini to get any screen resolution you want.

You may have noticed when running the game in Linux, that you can only set the screen resolution to either the X-Windows size, or 640x480, using the game GUI. Look inside the UnrealTournament.ini file (first in your home directory, ~/.loki/ut/System/UnrealTournament.ini, then in the game directory, /usr/local/games/ut/System/UnrealTournament.ini). In the [SDLDrv.SDLClient] section, you'll see two variables, FullscreenViewportX and FullscreenViewportY. Set them to whatever resolution you desire.

Installing Nvidia Drivers Under Linux

If you're using any Nvidia graphics card, install the Nvidia drivers! The drivers supplied with XFree86, though not bad, lack support for hardware OpenGL acceleration. Go to Nvidia's site and download their Linux drivers. The difference will be amazing when running Unreal Tournament.

Right now (19 March 2002) the page on Nvidia's site with their Linux drivers is here. You will download two files from them: the GLX driver file, and the kernel driver file. The instructions on the page should be pretty easy to follow.

A few "gotchas" though:

• Read all the instructions very carefully.
• When installing NVIDIA_GLX, the installer will probably complain that it needs XFree86 4.0.1 or higher, and then die, even though RedHat 7.2 ships with XFree86 4.1.0. Use rpm -ivh --nodeps NVIDIA_GLX....rpm to install it anyway. The --nodeps (that's dash dash nodeps) is what's important there, it will tell the installer to ignore the dependency problem, which isn't important.
• The instructions tell you to edit /etc/X11/XF86Config-4. X-Windows for us crashed when we restarted, but ran fine when we rebooted.
