1. Introduction
1.1. Preamble
Linux Quake sits at the crossroads of two computing revolutions;
GNU/Linux - the popular free operating system, and GLQuake - the first
"first person shooter" to use OpenGL. Thanks to John Carmack
releasing the software under the GPL we are able to enjoy it on non-
proprietary platforms. And, despite it's age, great new maps are
still regularly released.
1.2. About
This document is a guide to installing Quake and it's many related
games and modifications. It includes compilation notes, tips and
pointers to the best web resources, as well as some information about
Quake II, III and IV. You'll also find many issues relevant to Linux
gaming in general.
1.3. Notation
In some places, a shorthand is used to represent changes to a
program's source code. This is of the form:
- code to be removed
+ code to be inserted in its place
and is similar to the output of the GNU "diff" program when generating
unified patches.
Where the term "$PWD" is used, the user should already have executed
the command cd {Linux Quake directory}, and have this as their current
directory.
2. General Info
2.1. Getting Started
Installing Quake requires a few basic steps.
Get the Game Data Files
Getting the game data files is normally done by installing the
game <http://www.idsoftware.com/games/quake/quake> (or game demo
<ftp://ftp.idsoftware.com/idstuff/quake/quake106.zip>) using
Microsoft Windows, or an emulator such as Wine or Dosbox, and
then copying the id1 directory of the installed game to your
Linux Quake directory - making sure all files are in
``lowercase''.
Alternatively, you can use the lha utility
<http://freshmeat.net/projects/lhaforunix/> to extract the data
files. For early CDs, you must first
________________________________________________________________
cat /mnt/cdrom/quake101.1 /mnt/cdrom/quake101.2 > resource.1
________________________________________________________________
Once you have the resource.1 file, then type
___________________________________________________________________
cd /usr/local/games/quake
lha e {some directory}/resource.1
___________________________________________________________________
Later versions of the game, including WinQuake, come with the data
files in an uncompressed form and the id1 directory can be directly
copied from the CD.
Install a Quake Executable
The program you execute to run Quake is known as the ``game
engine''. There are several to choose from, but the simplest
choice is either TyrQuake
<http://prdownloads.sourceforge.net/uhexen2/quake-
lq-1.0.1.tgz?download>, or the more enhanced ``QuakeSpasm''.
After downloading or compiling a game engine, place this binary
in your Quake directory alongside the id1 directory.
Summary
Finally, you should have a directory structure similar to this,
with all files being in ``lowercase'':
/usr/local/games/quake +- quakespasm (or another game engine)
|
+- progs.dat
|
+- id1 -+- pak0.pak
|
+- pak1.pak
Now, from an xterm window, type (for example)
___________________________________________________________________
./quakespasm -fullscreen -width 800 -height 600
___________________________________________________________________
to start the game.
Help
This sounds simple, but if you are new to Linux and you are not
familiar with the command line, try one of these links for more
information:
· ``Trouble-shooting'' section
· The ``old version'' of this how-to
· Linuxgamers Quake How-To <http://www.linux-
gamers.net/modules/wfsection/article.php?articleid=42>
· Quake wiki <http://wiki.quakesrc.org/index.php/HomePage>
· The Linux Game Tome <http://www.happypenguin.org>
2.2. Command Line Options
Command Line Options are extra parameters that are typed on the Linux
command line following the program's name. Quake has a large number
of them, some of which vary from engine to engine. The most
useful/common ones are:
-window
Run the game in windowed mode
-fullscreen
Run the game in fullscreen mode
-game NAME
Load the mod NAME.
-mem N
Reserve N megabytes of memory for the internal heap. This
generally defaults to 8 or 16 meg, but must be increased when
playing larger mods.
-width WIDTH
window/fullscreen width
-height HEIGHT
window/fullscreen height
-basedir DIRECTORY
Use this directory by default
-sndspeed MHz
Set sound sampling rate (eg. 44100, 22050, 11025)
-sndbits N
Set sound bits to N = 8 or 16
-nosound
Disable sound. Necessary when sound is absent/unconfigured to
stop the game from crashing.
-nomtex
Disable GL multitextures.
-listen N
Allow a maximum of N players/bots to join multiplayer games.
-cddev DEVICE
Use DEVICE for playing the cd music
-nocdaudio
Disable cd audio
You can also append Quake commands to the Linux command line by
prefixing them with a plus sign. For example, to automatically start a
new game at hard skill, use
______________________________________________________________________
quakespasm +skill 2 +map e1m1
______________________________________________________________________
2.3. Game Console Commands
For more info see
<http://www.planetquake.com/console/commands/quake.html>
The console is an in-game command line at which you can issue
commands, change variables and cheat. It is toggled by pressing the
tilde "~" key when in a game. The main commands include -
god
Invulnerability
noclip
Walk through walls
notarget
Enemies won't attack player
timedemo DEMO
Play DEMO (eg. "demo1") at top speed and show frame rate
impulse N
Issue "impulse N"
These are in-game commands which can be given special uses. A
few usefull ones are:
· impulse 9 Give all weapons
· impulse 12 Select previous weapon (eg bind MWHEELUP "impulse
12")
· impulse 10 Select next weapon
· impulse 255 Give Quad damage
bind key
Bind a key to perform a command
map MAP
Load MAP
changelevel MAP
Load MAP without resetting player settings
quit
Exit to system
skill VALUE
value = 0 (easy) - 3 (impossible)
Degree of difficulty. Level must be restarted to take effect
r_wateralpha VALUE
value = 0.0 - 1.0
Opacity of water in maps with transparent water support (See
``Watervis'')
_snd_mixahead VALUE
value = 0.1 - 1.0
Raising this value is a good way to speed up the game at the
expense of some sound lag. I use 0.3 on my slower computers
gl_texturemode VALUE
value = gl_nearest | gl_nearest_mipmap_nearest |
gl_linear_mipmap_nearest | gl_linear_mipmap_linear
Worst to best texture quality.
r_shadows FLAG
flag = 0 | 1
Display model shadows
vid_wait FLAG
flag = 0 | 1
Sync video output with screen refresh
chase_active FLAG
flag = 0 | 1
Show player from third person perspective
3. Game Engines
3.1. TyrQuake
TyrQuake is a fairly complete project including OpenGL, Software Quake
and QuakeWorld clients, and other tools
<http://disenchant.net/utils.html> including the popular TyrLite.
Tyrann's focus is on a fully featured but minimalist cross-platform
engine.
The latest version is 0.60, which now supports the Power PC platform,
FreeBSD and per-user configuration files. Other newish features
include sophisticated command line completion, and a cool console
effect (gl_constretch).
Typing make will build all the clients. To compile only the single
player client, after unpacking the source code type:
make prepare tyr-glquake . Tyrann has a nice clean build system, but
if you wish to see compilation feedback, add V=1 to the command line.
A patched TyrQuake binary is available here
<http://prdownloads.sourceforge.net/uhexen2/quake-
lq-1.0.1.tgz?download>.
<http://disenchant.net/engine.html>
3.2. QuakeSpasm
FitzQuake <http://www.celephais.net/fitzquake> has long been the
defacto standard for the Quake mapping community, and this new project
is based on the SDL Port <http://www.kristianduske.com/fitzquake> of
Fitz.
3.2.1. Features
As well as great FitzQuake features such as skyboxes, fog, coloured
light, and support for huge maps, QuakeSpasm includes:
· 64 bit CPU support
· Should work with most SDL platforms
· Restructured sound driver
· Custom console background
· SDL CD audio
· Tweaked command line completion, and a map name autocomplete
· Alt+Enter toggles fullscreen
3.2.2. Tips
· scr_sbaralpha .99 - Give a nicer status bar
· maps - List available maps
· game GAMENAME - On-the-fly change of game
· ./quakespasm -fitz - Run game in FitzQuake mode
<http://quakespasm.sourceforge.net>
3.3. Darkplaces
Darkplaces is an amazing Quake engine with a great range of visual
enhancements and options for colour, effects and sound. It uses the
same Doom3 lighting features as Tenebrae and thus requires a more
powerful computer than GLQuake and QuakeForge.
It also supports many otherwise incompatible mods including
``Nehahra'' and ``Nexuiz'', and has improved support for the official
mission packs. Recent changes include improvements to the menuing
system, and speed increases, though there also appears to be some mod
compatability issues creeping in.
Havoc's file archive <http://icculus.org/twilight/darkplaces/files/>
can be a little confusing. The large "darkplacesengine" tarballs
include precompiled binaries and the game's source code in a second
tarball. To compile your own program uncompress the second tarball ,
type make to see a list of possible targets (programs), and select
one. For example - to build the OpenGL engine with ALSA sound type
make cl-release, or to build with OSS sound, make cl-release
DP_SOUND_API=OSS.
Thanks to LordHavoc for this great project.
<http://www.icculus.org/twilight/darkplaces>
3.4. Quore
From the Quore website:
Quore is an atmospheric Quake engine running on GNU/Linux
systems with enhanced graphics, increased limits, config-
urable HUD and ambiences, and different modes for changing
the gameplay. It is based on JoeQuake with additional
effects from Qrack, ezQuake and engine's limits tweaking
from Fitzquake
This game is great, and probably the most graphically modified Linux
engine. But it also has many niggling bugs.
<http://quore.free.fr/index.html>
3.5. QuDos Quake Ports
QuDos has done much work with Quake engines for BSD and Linux. In the
past he has ported Nehahra , JoeQuake and others, but currently has
only a couple available at his website.
His excellent ``NehQuake'' port is still available at LinuxQuake.Org
<http://linuxquake.org/index8.html> , but those after the source code
may try contacting him.
<http://qudos.quakedev.com/linux/quake1>
3.6. MFCN's GLQuake
Here you'll find some relevant documentation and trouble shooting
tips, and a basic version of OpenGL Quake for Linux. Fairly pain free
by Linux standards, it supports most Quake mods, but gamma
(brightness) support is broken.
<http://mfcn.ilo.de/glxquake>
3.7. Tenebrae
Tenebrae is a gorgeous Quake engine with lighting similar to that in
Doom III. It's is an old project requiring a good GPU, and may not be
compatible with all... the documentation is a fairly sparse.
There are several points of interest here...
· Tenebrae has an "easter egg". In the quit game dialog press "d".
· It includes the interesting "bumptest" and "zoo" maps.
· A custom Tenebrae-1.0 engine is included with the atmospheric
Industri <http://industri.sourceforge.net> mod.
· Tenebrae doesn't run user mods.
The Tenebrae installer
<http://www.liflg.org/?what=dl&catid=6&gameid=12&filename=tenebrae.quake_1.04-english-2.run>
will install the shareware Quake levels, and all fancy Tenebrae models
and textures, but is a 100 meg download. (Make sure to run the game in
32 bpp mode - see below). Try here
<http://www.cynapses.org/tmp/tenebrae/> for some binaries.
Compilation of the source code may not be straight forward. Firstly:
cd linux ; ln -s Makefile.i386linux Makefile ; make
If compilation fails with "../glquake.h:1137: conflicting types for
....", lines 1137 and 1138 need removing. You may also have to change
the gethostname declaration in net_udp.c thus:
- extern int gethostname (char *, int);
+ extern int gethostname (char *, size_t);
After compilation, copy the binary "debugi386.glibc/bin/tenebrae.run"
and the Tenebrae data files to your Quake folder. Finally, the game
only runs in 32 bpp colours (X11 colour depth 24), so restart X in
this mode if you have to, and execute the game with: tenebrae.run
-basedir $PWD. Alternatively you can start a new X session with the
command:
startx $PWD/tenebrae.run -basedir $PWD -- :1 -depth 24
<http://tenebrae.sourceforge.net/>
3.8. QuakeForge
QF is a comprehensive Linux Quake project. It has elegant graphical
enhancements, numerous single player and ``QuakeWorld'' clients and
Quake C tools. Amongst it's features are: an overhauled menuing
system, a new "heads up display", and in-game help.
Possibly because of it's size, QuakeForge hasn't been updated in years
and it's documentation was never quite finished. The usual "configure
&& make && make install" will build the whole project, but it does not
appear to support a minimal single player build option. QuakeForge's
default directory is "/usr/local/share/games/quakeforge", so ensure to
link to your "id1" directory from here. (For example ln -s
/usr/local/games/quake/id1 /usr/local/share/games/quakeforge/id1).
For information about building QuakeForge on the BSD Unices, see the
``FreeBSD'' section.
Kudos to the QuakeForge team for a huge project which has provided
much inspiration for other open source games.
<http://www.quakeforge.net>
<http://sourceforge.net/projects/quake/>
3.9. NPRQuake
Another Quake engine which has been ported to Linux but, as far as I
know, hasn't been touched in a few years is NPRQuake. Notably, it has
the ability to load different renderers on the fly, which is pretty
cool. The Linux port <http://www.geocities.com/coolguywithgun>
includes support for the cartoon renderer ainpr
<http://www.cs.unc.edu/%7Eadyilie/comp238/Final/Final.htm>, and works
really well for me.
The SDL version <http://www.tempestgames.com/ryan/> has rewritten
mouse and video code, but the sound APIs have not been ported to SDL,
and it is not a fully portable engine.
<http://www.cs.wisc.edu/graphics/Gallery/NPRQuake/>
3.10. Twilight Project
The Twilight Project "is a set of rather minimalist NQ and QW engines
that focus on insane rendering speed, it is however a bit unstable at
the moment."
This game is ~quick~, with a plain looking, but useful menu system, so
users with a slow computer should definitely give this a go. It also
has some unique graphical effects and an unusual user interface.
To compile version 0.2.2 of this project, you'll need the python
scripting language installed, and perhaps to make this change to
src/nq/pr_edict.c , line 1108:
- if (progs->ofs_strings + pr_stringssize >= com_filesize)
+ if (progs->ofs_strings + pr_stringssize >= (uint)com_filesize)
Executing scons.py will now (hopefully) build the binaries, and after
copying the single player client (twilight-nq) to your quake direc-
tory, type twilight-nq -basedir $PWD to start the game.
If you're having trouble with compilation, version 0.2.01 uses the
traditional "configure && make && make install" method, so you may
want to try it.
Game saves are an issue with this engine. There are no game save or
load menus, and this can only be done using the "F6" and "F9" keys to
quicksave and load. Additionally, this feature often won't work if you
started with the "map MAPNAME" command, so make sure you begin games
in a normal fashion, through the "Start Game" menu.
<http://icculus.org/twilight>
3.11. Audio Quake
This engine is for visually disabled people, and uses sound to help
with navigation. It includes OpenGL and SDL clients.
<http://www.agrip.org.uk/>
3.12. SDL Quake
This basic version of Quake is not really of interest to Linux users
as it uses a very old code base, and has few features. It's main
feature is the use of the SDL programming API for sound, video and
mouse handling, and should run on all SDL supported operating systems
without major changes.
SDL Quake does have a bug relating to music: running the game with an
audio CD in the drive will limit the game's speed. To avoid this
simply remove the CD, or use the -nocdaudio option.
The game runs at a fixed resolution; the width and height can't be
changed. To play in fullscreen mode, use the -fullscreen option.
<http://www.libsdl.org/projects/quake>
3.13. wmQuake
WindowMaker is a window manager for X11, and this tiny version of
Quake fits in an 64x64 pixel dockable applet. You can test it out
even if you don't have WindowMaker, but the game will crash if it gets
keyboard focus.
For the curious, this game can be benchmarked with timedemo demo1
after removing the "usleep" commands from sys_linux.c.
<http://freshmeat.net/projects/wmquake/>
3.14. Software Quake
For a more in-depth treatment of Software Quake, see the ``previous
version'' of this how-to.
The original WinQuake source
<http://www.quakeforge.net/files/q1source.zip> also came with two
pixelated versions of the game:
· X Quake (quake.x11)
· Svga Quake (squake)
but compiling them is no longer straight forward. It involves copying
Makefile.linux to Makefile, editing this file to remove the extra
targets , replacing /usr/X11/lib with /usr/X11R6/lib and typing make
build_release.
There are easier options though. ``TyrQuake'' and ``QuakeForge'' have
software clients, and there is also an old ``SDLQuake'' written by
SDL's author, Sam Lantinga, which should work on all modern platforms.
4. Mods
4.1. About
Quake has hundreds of user created levels - known variously as "mods",
"total conversions" or simply "maps". To run new maps, place the bsp
file into the "quake/id1/maps" subdirectory, and start Quake with the
+map MAPNAME option.
Installing mods is simply a matter of creating a subdirectory DIR and
extracting the contents of the mod zipfile/tarball into this
directory. It is then loaded by using the -game DIR command line
option and, sometimes, +map MAPNAME where MAPNAME is the mod's start
map.
For both maps and mods, all files should be in ``lowercase''.
4.2. Single Player Mods
There has recently been an effort to archive many Quake maps at
Quaddicted. Maps <http://www.quaddicted.com/spmaps.html>, Mods
<http://www.quaddicted.com/spmods.html>.
Some of the more notable mods are:
Travail
This recent mod is a must have. It includes 15 single player
levels, stunning bosses, and a couple of twisting spider
infested caverns. Distrans has also contributed a professional
quality soundtrack
<http://www.quaddicted.com/filebase/travail_soundtrack.zip>
composed of moody and interesting electronic vibes. Link
<http://www.quakeone.com/travail>
Quoth
Quoth began life as a sequel to the draw-dropping mod, Contract
Revoked <http://kell.spawnpoint.org/convoked.html>, but has
recently gained much support from mappers, as is becoming the
defacto extension of Quake I.
It's new features include numerous crazy enemies with strong AI,
destructable environments, and other items including ladders and
flashlights. Link <http://www.planetquake.com/necros/quoth/>
W a r p s p a s m
A huge atmospheric Quoth mod by Ijed. The latest and greatest.
Link <http://gimme.badsectoracula.com/warpspasm-readme.html>
Soul of Evil
Gorgeous medieval themed mod with two single player episodes, a
melee style arena mode and nice documentation. Many thanks to
Tronwyn, Fat Controller and their co-authors. Link
<http://www.planetquake.com/tronyn/soul>
Nehahra
Epic. Ambitious. Otherwordly. Nehahra is the definitive Quake
mod, supported in Linux by LordHavoc's ``Darkplaces'', and
``QuDos''' port of the NehQuake engine. It has some great models
and maps, uses fog effects well, and has an (optional) two hour
movie/demo which ties-in well with the original Quake "story-
line" but is also in desperate need of an edit.
Nehahra also features improved enemy AI - the grunts strafe
behind cover, and scrags in open space can be very hard to pin
down. New gamers may wish to disable this feature by typing
nomonsters 1 at the game console. Link
<http://www.planetquake.com/nehahra>
Zerst
Dark and bloody, with Doom's paranoiac atmosphere. A classic.
Zerst also has some good death match levels - Link
<http://www.quaddicted.com/zer.html>
Neil Manke's mods
Neil wrote the definitive Half-Life mod "They Hunger". The
quality and fun is in these maps too - alba01, alba02, sofsp1,
sofsp2, starshp2, Link <http://www.planethalflife.com/manke/>
Operation: Urth Majik
Oum is one of the few Quake 1 mods with a sci-fi feel. It has
five well made levels, with cut-scenes and many new weapons -
Download <http://disenchant.net/files/maps/oum.zip>, Link
<http://www.planetquake.com/fatty/oum/>
Scourge done Slick
SdS is a speed run through Mission Pack 1, Scourge of Armagon.
Hilarious and amazing. Link
<http://www.planetquake.com/QdQ/sds.html>
4.3. Commercial Mods
Mission Pack 1
Scourge of Armagon by Ritual Entertainment (formerly known as
Hipnotic Interactive).
After playing Armagon, you should also check out the Death's
Dominion <http://www.google.com.au/search?q=dd.zip> Level Pack.
Mission Pack 2
Dissolution of Eternity by Rogue Entertainment.
Both official mission packs are generally acknowledged as better
than the original game.
Malice
Very original Quake total conversion, with the greatest
(virtual) machine gun I've ever unleashed. Worth paying for.
Abyss of Pandemonium
Commercial mod now freely available: Link
<http://www.planetquake.com/impel>
Ravages of Apocalypse
Xmen mod! Great models. Shame about the game-play. ...When good
mods turn bad.
This mod has now been released free of charge, and can be found
here <http://www.zerogravity.com.au/xmen/>.
Shrak
One of the first commercial mods. It has well modelled and
totally new monsters, but the game-play doesn't cut it.
5. Multiplayer
5.1. Nexuiz
Nexuiz is a stand-alone game using the Darkplaces engine. The recently
released second version is a 200 meg download, and includes Linux and
Windows binaries, source code, and a new campaign mode.
This engine makes use of many advanced lighting features, so users
with less powerful video cards should try disabling these to run the
game at a decent speed.
<http://www.nexuiz.com>
5.2. EzQuake
This project now works for me, and is looking very nice.
As well and as GL, X11 and SVGA clients, it has serious graphical and
game-play enhancements and some nice documentation. It is definately a
project to keep up with.
Sound may be an issue. It defaults to ALSA but to start with OSS try:
"ezquake-gl.glx +set s_device /dev/dsp". To compile the GL client,
type "make glx". You may have to change the Makefile thus:
- LDFLAGS = -lm -lpthread
+ LDFLAGS = -lm -lpthread -L/usr/X11R6/lib
<http://ezquake.sourceforge.net>
<http://ezquake.sourceforge.net/forum/>
5.3. FTE QuakeWorld
An ambitious project, FTE Quakeworld <http://www.fteqw.com> aims to
offer support for multiplayer Quake as well as similar projects such
as Hexen II. GB reports: "The FTE engine also runs NQ stuff and even
Nehahra... even in software"!
5.4. ProQuake
From the ProQuake website: "...What you will find is a rock solid set
of enhancements to unmodified netquake. Things that quake should have
had from the get go.. like precise aim. Small, simple changes that
improve the quality of netplay enormously. ProQuake is fully
compatible with standard NetQuake. .... ProQuake is also fully
compatible with the advanced features of Clanring CRMod++ version
6.0."
ProQuake 4 <http://quakeone.com/proquake/>
Older ftp repository <ftp://ftp.runequake.com/quake/engines/proquake>
5.5. ZQuake
ZQuake is a QuakeWorld client with good multiplayer support.
<http://zquake.frag.ru>
5.6. Other Game Types
5.6.1. Deathmatch
5.6.2. Capture the Flag
5.6.3. Rocket Arena
5.6.4. Rune Quake
5.7. Other Multiplayer Mods
Painkeep
Popular deathmatch mod including new weapons.
Soul of Evil
``SoE'' in arena mode has some great melee action.
Battle Mech
Battle Mech is a top down Mechwarrior style mod. Make sure to
use the 1.1
<http://static.condemned.com/files/bmech_stuff/battlemech-1.1.tar.gz>
tarball.
<http://static.condemned.com/index.shtml>
5.8. Bots
Bots are computer generated players with artificial intelligence. Some
require "waypoints" to successfully navigate.
Frikbot
Popular bot designed for easy integration into mods.
Frogbot
Highly regarded as one of the best, hundreds of maps supported.
Omicron
Venerable mod by Mr. Elusive, who went on to create Gladiator
bot for Q2 and the Q3:Arena bots. Needs no waypoints.
5.9. Servers
XQF and QStat
XQF <http://www.linuxgames.com/xqf/index.shtml> is a feature
rich game server browser and launcher for Quake and many other
games. It is dependent on the separate program, QStat
<http://www.qstat.org/> , which displays information about
Internet game servers. You'll also need the Gnome Gtk and Gdk
toolkits.

6. Quake Sequels
6.1. Hexen II
Hexen II is a colourful adaption of the Quake engine, and in terms of
source code and theme is much closer than Quake II to the original
game. Unfortunately, Raven Software <http://ravensoft.com> released
the game with many rough edges... So beautiful, yet so cruel.
Hammer of Thyrion <http://uhexen2.sourceforge.net> is the main Linux
Hexen II port , and has had much work done towards squishing bugs and
enhancing the OpenGL graphics. While it is not as widely distributed
as Quake, the HoT demo includes some of the game's best levels and is
available from the Sourceforge project page
<http://sourceforge.net/projects/uhexen2>.
Mappers should note the Quest <http://quest-
ed.sourceforge.net/index.html> world editor, and HexenC compiler
FTEQCC <http://www.fteqw.com>.
6.2. Quake II
Quake II is the sci-fi themed sequel to Quake. Early Linux releases
weren't very solid, especially the mouse handling, but there is now a
few related projects to choose from.
Open Source Projects
QuDos' Quake II <http://qudos.quakedev.com/linux/quake2> is the
most notable. It is based on Icculus Quake II
<http://www.icculus.org/quake2/>, and includes some beautiful
graphical enhancements - including cell shading - and support
for FreeBSD and XMMS plugins. Another project still in
development is Quetoo
<http://jdolan.dyndns.org/jaydolan/home.html> which has speed
and security enhancements, but also a very stripped back
interface and a few bugs.
Yamagi Quake II <http://www.yamagi.org/quake2>, also based on
Icculus, is an active Q2 project focusing on single player game
and cooperative game modes.
Qfusion <http://hkitchen.net/qfusion/> appears an interesting
project... that's slipped under my radar till now. An advanced
multipurpose engine based on Quake II.
Older projects include Michael Olson's source
<http://www.cs.odu.edu/~olson/linux/quake2-0.12-1jag.src.rpm>
and binary
<http://www.cs.odu.edu/~olson/linux/quake2-0.12-1jag.i386.rpm>
rpms (which appear to be based on an old Icculus release) and
the QuakeForge Quake II
<http://www.quakeforge.net/files/quake2forge/quake2-0.3.tar.gz>
project with support for multiple operating systems. On a
slightly different note - the Jake2
<http://www.bytonic.de/html/jake2.html> project is a version of
Quake II written in Java.
Notes
A common command line option is:
which tells the game to start in OpenGL mode.
See the ``old version'' of this how-to for other Quake II
troubleshooting tips.
Mods
Digital Paint 2 <http://www.planetquake.com/digitalpaint/> is an
"original" multiplayer game based on the Quake II engine. It's
colourful and fun nature is a departure from the usual dark tone
of most Quake games. Being a totally remodeled game, it doesn't
require you to have the original Quake II ;->.
Argonium <http://www.planetquake.com/td/argonium/> is a slick
looking deathmatch mod which is also freely distributable.
6.3. Quake III Arena
Quake III was one of the first games to receive a full Linux
commercial release. It's a great game which more than survives. Mods
are numerous, and of better visual quality than Quake I or II. For
more info about installing the game, try idsoftware's Faq
<http://zerowing.idsoftware.com/linux/q3a/INSTALL>, or Linuxgamer's
Quake III How-To <http://www.linux-
gamers.net/modules/wfsection/article.php?articleid=30>.
The retail add-on Quake III Team Arena is supported and, despite
getting ordinary reviews, is a great game. Most user mods should work
with Linux. The Linux Gamers FAQ reports:
Yes, ... modifications work in Linux as long as they are compiled to the
Quake III ... VM bytecode as advised by id software. ... modifications
compiled to Windows library files will not work.
Open Source Projects
The Icculus Quake III Project which has recently moved to
IOQuake <http://ioquake3.org>. They are adding extra features,
including support for Star Trek Voyager: Elite Force Holomatch
(multiplayer).
Sourceforge Quake III - Cell Shading
<http://q3cellshading.sourceforge.net>
Mods
Warsow <http://www.warsow.net> is a cell-shaded cartoon style
total conversion using a heavily modified engine. It's interface
is very slick, graphics to die for, and gameplay is ok.
World of Padman <http://www.worldofpadman.com/> is a high
quality stand-alone conversion. It's set in a miniature suburban
world with a bizarre cartoon theme, and is currently multiplayer
only but with full bot support.
In Alien Arena <http://red.planetarena.org> you're matched
against pin headed martians in unbelievable OpenGL environments.
The Dark Conjunction <http://www.planetquake.com/tdc/> is an
atmospheric Q3 single player conversion.
Try the alien themed Tremulous <http://tremulous.net> for an
original multiplayer mod.

6.4. Quake IV
Quake IV is an epic FPS from Raven Software <http://ravensoft.com>.
It is based on the Doom-III engine and has high hardware specs: A 2GHz
P4 (or AMD equivalent) and 512meg ram are the official minimum
requirements. It's a beautiful game which should really be played
with the graphical settings set to "medium" or "high". For this reason
the author recommends against using entry level cards such as the
FX5200.
The game runs well under Linux, but still has a couple of issues:
· Quake IV only runs in 32 bpp colours (X11 colour depth 24), so
restart X in this mode if you have to. Attempting to run in 16 bpp
colours will give you an error message like:
Couldn't find matching GLX visual ..... Sys_Error: Unable to
initialize OpenGL.
Alternatively you can start a new X session with the command:
startx `which quake4` -- :1 -depth 24
· The Alsa sound libraries are used by default. To start with OSS
sound , type:
quake4 +set s_driver oss
· The Quake IV DVD Edition comes with several promotional movies.
Although the movies appear to be Windows executables, they are in
fact Bink videos, and can be viewed with the Linux Bink Player

7. Mapping Tools
Creating mods is done with map editors and compilers, but also
involves .... texture creation, making pak files, modeling, skinning,
editing sound and graphics files, and writing your own progs.dat with
Quake C. Linux support is available, but is not comprehensive.
Quake C is Quake's own game language (it was the first game such), and
it allows mods to work seamlessly on all operating systems.
7.1. World Editors
GtkRadiant <http://www.qeradiant.com/>
The main map editor for Quake. It is based on id Software's own
editor, and requires OpenGL.
Quest <http://quest-ed.sourceforge.net/index.html>
A multi-game world editor. It has a stiff learning curve, but
is very efficient after you master it.
· keyboard shortcuts for effortless cut-and-paste operations on
multiple brushes and entities
· easy vertex manipulation using keyboard shortcuts and the
mouse
· edit the properties of multiple entities at once
· texture and align multiple faces
· texture locking function (crates)
· can rotate, stretch and mirror textures
· support for groups
· variable grid size down to 1 px
7.2. Tools
Bjptools <http://qexpo.tastyspleen.net/uploaded/157/bjp-
tools-090908.zip>
Linux port of the most used map compilers.
· includes treeqbsp, vis and light
· supports rotating entities
· doesn't support coloured lights
· modifications by Bengt Jardrup, Greg Lewis, and others
Tyrutils <http://disenchant.net/utils.html>
Tyrann's popular map compilers, including qbsp, vis and tyrlite.
Supports rotating entities and coloured lights.
Hmap2 <http://icculus.org/twilight/dark-
places/files/hmap2build20080616.zip>
LordHavoc's compiler. It can compile leaky or incomplete maps
(use only for testing!) and does a ton of other stuff, including
coloured lighting.
QEU <http://gamers.org/pub/idgames2/utils/bsp_pak_tools/qeu03.zip>
Command line tools to handle pak and wad files (source code
only).
FTEQCC <http://www.fteqw.com>
Comprehensive, advanced QuakeC compiler with gui and command
line versions. If this one can't compile it, nothing will!
FrikQCC <http://www.inside3d.com/frikbot/frikqcc>

7.3. Tools needing Wine
Wine <http://www.winehq.org/> is a project that allows many Windows
programs to work with Linux.
Wally <http://www.telefragged.com/wally>
Multipurpose texture editing tool. Can batch convert BMP files
to Quake textures, etc. Also provides several paint functions,
and macros such as rivets and decals.
The Quake Army Knife <http://dynamic.gamespy.com/~quark/>
QuArK is a multipurpose Quake editing tool. It loads, edits and
exports multiple file formats, and has matured into a multi-
game, multi-format tool. Some functions are broken though, and
it may not work with all versions of Wine.
Q1Rad <http://icculus.org/homepages/riot/q1rad.zip>
Light tool that does radiosity-based lighting, like Quake II.

8. Trouble-shooting
Other trouble-shooting resources can be found at: The Linux Gamers
FAQ <http://www.icculus.org/lgfaq>, Jn's GLQuake Site
<http://mfcn.ilo.de/glxquake>, and the ``old version'' of this how-to.
Often, using an alternative game engine such as ``QuakeSpasm'' or
``Darkplaces'' will fix mouse and sound related problems.
8.1. Bash Won't Start the Program
"bash: ./glquake.glx: Permission denied"
· The binary may not have the executable bit set. Type chmod +x
glquake.glx to fix this.
· If the program is located on a windows partition, it is possible it
has been mounted with the noexec option.
Type (as root): mount -o remount,exec /mnt/windows
"bash: glquake.glx: command not found"
· Bash may not be including the current directory in it's path.
Type: "export PATH=$PATH:."
8.2. Program Dies at Startup
This is not good, but some simple options to try are:
· - use -nosound to test if sound is the problem.
Sound issues are covered in detail below.
· - use -noudp if network is unconfigured.
· - use -nocdaudio if cdrom is absent.
· - use -height, -width and -fullscreen command line options to
select a screen mode you know is properly configured.
e.g. glquake.glx -width 800 -height 600 -fullscreen -nosound
Files not lowercased or Data files missing.
Linux Quake requires (most) filenames to be in lowercase. If you get
an error similar to "Error: W_LoadWadFile: couldn't load gfx.wad" it
means the game can't find the data files, possibly because they are
not all lowercase.
· Make sure you have the subdirectory "id1" (not "ID1") containing
the files "pak0.pak" and "pak1.pak".
· For a comprehensive lowercase utility, download this utility
<http://prdownloads.sourceforge.net/uhexen2/lowercase?download> or
visit <http://filerenameutils.sourceforge.net>.
Missing libraries: "error while loading shared libraries: libGL.so.1:
cannot open shared object file"
A message like this means the program cannot run because it can't find
a system file it needs. Perhaps:
· File is not installed - Just check with your package manager and
install the correct package.
· Links aren't properly set-up. If you have (say)
/usr/lib/libGL.so.1.2, but get the above message, you should be
able to remedy this with ln -s /usr/lib/libGL.so.1.2
/usr/lib/libGL.so.1
Dynamic libraries (or DLLs as they are known to Windows users) can be
quite complex. For more information try the ldd and ldconfig man
pages.
"Memory overwrite in Sys_Printf"
· This error means you need to edit file sys_linux.c, procedure
Sys_Printf, and change text[1024] to text[4096] and recompile.
Many versions of Quake have what appear to be two versions of this
procedure, but one is always commented out. Obviously you'll need
to change the value in the correct procedure.
Problems with GCC 4
· If you're experiencing core dumps and are using version 4.0 of the
GNU compiler, see ``Compilation Issues'' below.
8.3. Program Dies Loading Level
· Many mods require extra memory. Use the -mem 64 option to allocate
64 meg of memory for the heap.
· In some cases, this problem can be sound related. Try some of the
tips in the sound section.
· A few newer mods just won't work with standard GLQuake, and need an
enhanced ``game engine''. ``Darkplaces'' has the best large map
support under Linux, but some are even too big for it, and are
unsupported under Linux.
8.4. Game Runs Slowly
Most Quake games rely on OpenGL (libGL.so) for their graphical
features. Setting up OpenGL is beyond the scope of this document.
Very slow performance means you're probably using Mesa GL instead of
proper hardware GL acceleration.
Performance gains can also be made by disabling fancy effects such as
light bloom, and by slowing sound mixing with the ``console command''
"_snd_mixahead .4"
Minor game slowdown's with Nvidia hardware can also be attributed to
the use of conflicting AGP drivers. For more info about this see
``Nvidia AGP Issues''
8.5. Sound Problems
For more information see the ``drivers'' section.
An error such as: "/dev/dsp: Device or resource busy" indicates some
program is already using your sound card, and you will have to halt
this program to get Quake sound effects.
· From the Linux command line, type killall artsd or pulseaudio -k to
terminate either of these popular sound daemons.
· Alternatively, to run Quake through the KDE sound daemon, type
artsdsp glquake.glx ...
"Quake engine games exit, and I see an error about mmap!"
· The Linux Gamers FAQ <http://www.icculus.org/lgfaq> recommends
"Your sound card/driver doesn't support this needed feature.
However, if you use KDE/arts you may be able to bypass this with
the -m switch to the artsdsp wrapper".
Make sure the artsd program is running by typing ps -A | grep artsd
and checking that this command returns at least one non-empty line.
Then type artsdsp -m glquake.glx.
· Try alternative sound drivers as outlined in the ``Sound Drivers''
section.
Sound stutters or is not very good.
· See the sound note in ``Compilation Issues''.
· Try using the -sndspeed or -sndbits option(s), or swapping sound
drivers.
SDL provides a simple way of changing the sound driver using the
SDL_AUDIODRIVER environment variable. Run the game using a command
line like:
SDL_AUDIODRIVER=xxx darkplaces-sdl
Valid values on linux are: dsp (uses OSS), alsa (uses ALSA), esd (uses
the ESD daemon), and maybe arts (uses the aRTs daemon)
8.6. Compilation Issues
The dynamic nature of GNU/Linux means compiling old software is often
hard work, and even small hurdles are impossible for people not
experienced in C programming. Below are a few relevant issues.
8.6.1. GCC-4.x
The GNU C compiler has recently had a major revision, and most
modern distributions now include GCC-4.1. (To find out which
version you are using, type gcc --version). The author generally
uses GCC-3.2.2 , and people using GCC-4.x may find extra problems
when compiling programs:
Warnings
GCC-4.x issues many more compilation warnings than 3.x. These
are small errors that can generally be ignored, but when the
compiler is given the "-Werror" flag, warnings will bring
everything to a halt. To fix this you can safely remove the
"-Werror" from the program's Makefile.
Slurred Sound
Yet another sound issue. This common problem is fixed by
altering snd_mix.c thus:
- snd_scaletable[i][j] = ((signed char)j) * i * 8;
+ snd_scaletable[i][j] = ((j < 128) ? j : j - 0xff) * i * 8;
Optimizations
GCC-4.0 in particular had a problem with "-O" flags breaking
some variable type-casting. If you are able to compile the
program , but it segfaults, try disabling these optimizations by
removing the "-O" options from any makefiles.
If you are having troubles compiling with GCC-4 which weren't there
previously, it's possible to install GCC-3.x alongside 4.x. Most
people will want to look for precompiled packages from their Linux
distribution.
Once GCC-3.x is installed, the program must then be told to compile
with this version rather than the default 4.x. Projects that come
with configuration scripts will often have options for defining which
compiler to use (type ./configure --help and look for hints), and
other times you be able to use export CC=gcc32 or edit the Makefile
and replace occurrences of "gcc" with "gcc32" (or "gcc-3.2.2", etc)
manually.
8.6.2. 64 Bit CPUs
Most of these legacy programs will probably not work as 64 bit
binaries. ``QuakeSpasm'' is an exception.
It is still possible, however, to compile 32 bit binaries on a 64 bit
operating system. To do so, edit Makefiles and add "-m32" to the load
and compile flags (LDFLAGS, CFLAGS). This tells GCC to build and link
a 32 bit program (if the 32 bit SDL and OpenGL libraries are also
installed). You may also have to disable the use of x86 assembly.
If you are having trouble running 32 bit apps, try using the linux32
command. For example: linux32 tyr-glquake.
8.7. Other Issues
Game is too dark
If changing the brightness setting in the options menu doesn't
work, you can use the xgamma program to brighten the whole
display.
· Type xgamma -gamma VALUE before running the game, where VALUE
is a number larger than 1. When you've finished, use xgamma
-gamma 1 to restore the brightness.
This tip will not work with poorly supported hardware. For
Voodoo 1/2 users, visit here <http://sourceforge.net/docman/dis-
play_doc.php?docid=28982&group_id=124987> for more information.
Mouse look
"This game won't let me look around properly. %$!$@"
· Bring down the game console with the "~" key and enter
+mlook.
Mouse doesn't work properly
Try the following -
· Start the game in fullscreen mode by using the -fullscreen
option.
· From the game console, type _windowed_mouse 1
· If still without success, try the ``QuakeSpasm'' or
``Darkplaces'' SDL clients. Typing export
SDL_VIDEO_X11_DGAMOUSE=0 before starting the game will
disable hardware dga mouse.
Game saves fail / Options not remembered
If you are running Quake as a normal user and experiencing these
problems it's probably due to having insufficient privileges to
write to the game directories. Solutions include:
· Run the game as super user: Type su and enter root's password
before typing glquake.glx ... to start the game.
· Change the game file permissions. Unix operating systems have
strong security preventing unauthorized or accidental file
changes. The simplest way to overcome this in a single user
environment is to become super user and change ownership of
the quake directory with (as root): chown -R USERNAME
/usr/local/games/quake. However it is recommended users read
the chmod and chown man and info pages to better understand
Unix file permissions.
· In full multi-user environments it is recommended using the
``Darkplaces'', ``TyrQuake >= 0.56'' or ``QuakeForge'' game
engines, which correctly place per-user data in their home
directory.
Quake uses a confusing method of saving and restoring game
options, especially when playing add-ons, and game options
sometimes have to be reinitialized even though file permissions
are not an issue. In such cases, the author can offer no simple
advice %-/.
Crazy polygons
Some mission-packs/mods for Quake can cause existing
player/monster models to be drawn with lines all over the place.
To fix this, delete the directory "quake/id1/glquake". When you
next run the game, it will remake this directory and everything
should be fine.
Lines on screen
A common problem with 3Dfx cards is a shower of flickering lines
on the screen.
· From the game console, type gl_ztrick 0.
White textures and other graphical anomalies
Some Quake engines use an OpenGL speed-up known as
multitexturing. This normally works fine, but if you are
experiencing glitches you can disable this feature with the
-nomtex option.
Older video cards may occasionally draw single models in white.
See the PlanetQuake command list
<http://www.planetquake.com/console/commands/quake.html> for in-
game GL variables to fine tune performance.
Glibc Problems
Some Linux software come as a Loki Installer shell archive with
a ".run" suffix. The following tip is from the Icculus Gamers
Faq:
Q: I'm using {random loki_setup based installer}, and it's telling me the "installation doesn't support glibc-2.1" or something
A: Just type the following before running setup.sh [or the installer]: export SETUP_LIBC=glibc-2.1.

gamers.net/modules/wfsection/article.php?articleid=31>
8.8. Sound Drivers
There are two major Linux sound systems - Open Sound System and ALSA.
If you are experiencing sound problems and the trouble-shooting
section hasn't helped, you may consider changing the sound driver.
This can be hard work, and is only for experienced users.
To ascertain which driver you are currently using, type lsmod to list
currently loaded kernel modules. The ALSA sound modules have verbose
names starting with "snd_", while the OSS modules have more terse
names. For example, the ALSA Sound Blaster Live module is
"snd_emu10k1", while the OSS module is "emu10k1". Since Linux kernel
2.6, ALSA has been the standard sound system, while 2.4 and earlier
were more likely to come with OSS sound.
Information about ALSA can be found at the Alsa Homepage
<http://www.alsa-project.org> and Linux Journal's Guide to ALSA
<http://www.linuxjournal.com/node/8234/print>.
For those already with ALSA wishing to try the OSS modules, a kernel
recompile <http://www.tldp.org/HOWTO/Kernel-HOWTO/> is probably
necessary.
9. Other
9.1. Nvidia
Nvidia's drivers for all of their modern video cards are not open
source. Because of this many distributions do not include them. If
your Nvidia card is running slowly this is probably the cause and you
should visit <http://www.nvidia.com> to download the Linux installer.
In the author's experience these drivers are great, but not all
versions work 100% with all cards and kernels. If you have a
misbehaving Nvidia video card, try a different driver.
9.1.1. XOrg AGP Issues
With Nvidia's proprietry drivers installed, Linux can use either
AGPGART or Nvidia's AGP drivers for AGP access. This option is set by
"NvAGP" in your /etc/X11/xorg.conf file.
From Nvidia's README:
______________________________________________________________________
Option "NvAGP" "integer"
Configure AGP support. Integer argument can be one of:
Value Behavior
-------------- ---------------------------------------------------
0 disable AGP
1 use NVIDIA's internal AGP support, if possible
2 use AGPGART, if possible
3 use any AGP support (try AGPGART, then NVIDIA's
Please note that NVIDIA's internal AGP support cannot work if AGPGART is
either statically compiled into your kernel or is built as a module and
loaded into your kernel.
______________________________________________________________________
In the author's experience, Nvidia's AGP is necessary in order to get
the linux kernel's suspend to ram working properly, and is also
slightly faster. Users with kernels with built-in AGPGART need to add
agp=off to their boot loader in order to use the NvAGP driver.
9.1.2. Tweaks
These tweaks are for users with a GeForce video card (or better) and
Nvidia's proprietary drivers. They are accessed using the bash
command export {variable}={value} and then starting the Quake engine
from the same command line. Alternatively, recent drivers have a
nvidia-settings command which starts up a user-friendly control panel.
Full details of these tweaks are in the Nvidia README, normally
installed at "/usr/share/doc/NVIDIA_GLX-1.0/README.txt"

Synchronize Picture Redraw
export __GL_SYNC_TO_VBLANK=1
Synchronizes GL output with your monitor's vertical refresh,
giving a more stable image especially on slower video cards.
9.2. 3Dfx
While new versions of XFree and XOrg have great support for Voodoo 3,
4 and 5, early 3Dfx hardware such as Voodoo1, Voodoo2 and Rush are no
longer hardware accelerated. To get OpenGL working for these cards,
you'll need to download, install and/or compile the software libraries
called Glide and Mesa, though this is not trivial. The author does
have precompiled libGL for the Voodoo2, and his patched TyrQuake
<http://prdownloads.sourceforge.net/uhexen2/quake-
lq-1.0.1.tgz?download> includes proper 3Dfx brightness control. Here
<http://sourceforge.net/docman/display_doc.php?docid=28982&group_id=124987>
is a README for old 3Dfx cards.
9.3. FreeBSD
The author has limited experience with this OS and has tested projects
on FreeBSD 5.3 with Nvidia's proprietary drivers. ``Darkplaces'',
``QuakeSpasm'', ``TyrQuake'' and ``Hammer of Thyrion'' work well with
this system.
``QuDos'' has recently ported several engines
<http://qudos.quakedev.com/linux/quake1> to Linux and has recently
started work on FreeBSD compatibility. His great Quake II project
<http://qudos.quakedev.com/linux/quake2> is also now BSD friendly.
For basic GLQuake support, you can find a hacked FreeBSD binary and
source tarball here
<http://prdownloads.sourceforge.net/uhexen2/GLQuake-FreeBSD-
sa-1.0.tgz?download>.
``QuakeForge'' is a comprehensive Quake project, but may have
installation issues with newer FreeBSD releases. The memory allocator
routine "alloca" is not correctly detected on FreeBSD 5.3. The fix is,
after running "configure", to add "#define C_ALLOCA 1" to
"include/config.h" and undefine other ALLOCA variables. Another issue
is the opening of plugins. If the project builds, but you can't get
the console or menus, you may have to enable static plugins using
configure LDFLAGS=-lpthread --with-static-plugins.
9.4. QNX
QNX is a commercial real-time operating system, probably most notable
to hobbyists as being a successful microkernel OS. ``SDL
Quake''-1.0.9 compiles and runs on QNX-NC-6.2.1 after running
configure --host=QNX and then making these changes:
Makefile:
-LIBS = -L/usr/local/lib -lSDL -lm -lph -lasound
+LIBS = -L/usr/local/lib -lSDL -lm -lph -lasound -lsocket
net.h:
-extern unsigned long htonl (unsigned long hostlong);
-extern unsigned long ntohl (unsigned long netlong);
sys_sdl.c:
-#include <sys/shm.h>
-int psize = getpagesize();
+int psize = _SC_PAGESIZE;
9.5. Transparent Water and VisPatch
The game variable "r_wateralpha" allows for water transparency - but
most maps don't have the necessary "vis" information. There are two
ways to get this. After setting r_wateralpha < 1.0, issuing the
console command r_novis 1 enables the game to calculate it's own vis
information at the penalty of cpu cycles. Alternatively, vispatch is
a utility that patches your Quake/QuakeWorld levels to support
transparent water.
To do this you'll need the vispatch utility, as well as the vispatch
data files <http://www.atomicgamer.com/directory.php?id=3138> for the
game you are patching.
To patch the main data files in "id1" - from your Quake directory -
type vispatch -dir id1 -data id1.vis
Vispatch Homepage <http://vispatch.sourceforge.net/>
9.6. Quake Inspired XTerms
Quake's in-game console is a great feature and has been adopted by
many other games. Now you can also use the 'tilda' key to access X
terminal windows. Both Yakuake <http://yakuake.uv.ro/> and Tilda
<http://tilda.sourceforge.net/> are projects inspired by this idea.
Unfortunately neither are easy to install from source. Yakuake is a
KDE application and needs the KDE development packages, and compiling
Tilda is more complicated. It requires a couple of unusual libraries,
and gave this author compilation errors, so perhaps looking for a RPM
package is a better choice. The author can recommend Yakuake as a
very handy X terminal.
9.7. Launching maps and demos
<http://www.quaddicted.com/?p=374>
9.8. Interest
· Because of the way the original game renders the sky, any map with
numerous outdoor enemies suffers a big performance hit.
· You can jump further when strafing than when going forward or back
8-)
· The timedemo demo1 command is a great way to benchmark your system.
· Rocket-jumping is the technique of using a rocket or grenade
explosion to jump further than normal. For a demonstration see the
Scourge done Slick speed run.
· Popular games derived from the Quake engine include - Return to
Castle Wolfenstein, Half-Life, Star Trek Voyager - Elite Force,
Soldier of Fortune, American McGee's Alice, and - distantly - Doom
III.
9.9. Quotes
· John Carmack -
"At this time (march '97), the only standard opengl hardware that
can play glquake reasonably is an intergraph realizm, which is a
VERY expensive card"
· From the original Quake How-To -
"Hardware-accelerated OpenGL Quake is Quake the way God intended it
to be. There is no substitute, and once you've experienced it
there's no going back."
· Func Message Board -
"... This Will Produce A Fully Functional Bouncing, Exploding
Zombie."
Sounds like fun :-)
· Quake Wikipedia -
"Quake and its three follow up games, Quake II,Quake III Arena and
Quake 4 (which many do not regard as true sequels), have sold over
4 million copies combined. In 2005, a version of Quake was
produced for mobile phones."
· Moby Games
(by Pathogen)
"... Quake was the first FPS to introduce realistic lighting and
shadows. Of course, this came at a price. Quake has taken a lot of
flak because it's all dull brown and grey. This was necessary
because it was the only way to get the lighting to work properly.
Since each surface needs a wide variety of reserved colors for
displaying darkened/brightened portions of the surface, the game
was limited to just a few colors and all their respective shades."
(by Ashley Pomeroy)
"Almost incidentally, Quake introduced the now-standard concept of
a FPS control interface. Although the specifications required a
Pentium, Quake ran acceptably well on a 486 DX4/100"
· Happy Penguin Q3 Forum -
As for [Q3] open source.....earliest date seems to be second half
2005. The reason? They are still selling the code, over 5 years
later to game devs. Either they are stupid devs, or the Q3 code
still offers something....I'm inclined believe the latter.
· Slashdot Tenebrae Forum -
... this ... now officially labels this guy as a badass graphics programmer. I can hear it now:
MR. BURNS: "I need a programmer! Get John Carmack on the line!"
SMITHERS: "He's unavailable sir."
MR. BURNS: "Then get me his non-union Belgian equivalent!"
9.10. Glossary
ALSA
Advanced Linux Sound Architecture <http://www.alsa-project.org>.
API
Application Program Interface. The computer libraries which are
used when programming, and link the game to the hardware.
Bot
A computer generated player with artificial intelligence
(cough), in a multiplayer game. Used to play multiplayer when
no-one's around or not connected to a network.
Client
This word is used in two subtly different ways. In single
player, the Quake game is known as a client, with different
clients using their own graphics libraries (for example, the GL
client "quake.glx" or the X11 client "quake.x11"). The usage is
similar in multiplayer games, but also means the per-user
program which connects to a single "server" program which lets
all the players exist in the same world.
FPS
First Person Shooter. A shooting game viewed from the "first
person" perspective.
Mod
Modification to the original Quake game - varying from a
complete game overhaul (total conversion) to simple map/model
reworks. Quake was designed to allow for ease of platform
portability with it's own computer language "Quake C" giving
mappers control over most every aspect of their Quake world.
Noob
Newbie. Someone new to a computer related topic.
Patch
A software patch (or diff) is a single file used to alter a
source code tree before compilation. It is often used to fix
bugs or add new features that the original author didn't
include.
Usage of the GNU patch utility is of the form patch [--dry-run]
-pNUM <FILE where NUM is the number (usually 0 or 1) of
directories to strip from the patch file. This number is not
obvious except to unix gurus, but using the "--dry-run" option
will let you test run patch so you can find the correct NUM.
...Using the wrong number will make patch output all sorts of
cryptic messages which can be terminated with a control-C
character.
Of course you could always type man patch and learn for yourself
how to use this powerful unix command. ;-/
SDL
Simple DirectMedia Layer <http://www.libsdl.org/> cross platform
hardware API widely used in Linux games.
Segfault
A broad term indicating a program is faulty and terminated
abruptly. Depending on the bash shell's ulimit -c setting, a
dump of the program's image (coredump) may be left behind for
examination with the GNU debugger (GDB).
Server
A program central to multiplayer games to which every player
connects.
Tarball
An archive file such as somefile.tar created by the "tar"
program. It is often compressed using the programs "gzip" or
"bzip2", in which case it will normally end in the letters .gz
or .bz2. The extension .tar.gz is often shortened to .tgz.
