This document is a modern guide to id Software's Quake game, with some information about
QuakeWorld , Quake II, III and IV.

</abstract>

<toc>

<sect> Introduction

<sect1> Preamble <p>

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 the 3D graphics library OpenGL.  Quake has a loyal community
still making games ten years  after it's release by ID Software, and
thanks to John Carmack releasing the software under the GPL, people are able to
enjoy it on non-proprietary platforms.
<newline> <newline>
Does all this mean our game is important ?  No...  It's just fun ;-)

<sect1> About <p>

This document is not an exhaustive how-to about setting up any particular
program, but an overall guide to Quake, including compilation notes, tips, and
pointers to the best web resources.
It concentrates on the many engine rewrites and incredible add-ons which make
Quake the phenomena it is.

<sect1> Notation <p>

In some places, a shorthand is used to represent changes to a program's source code.
This is of the form:
<verb>
- code to be removed
+ code to be inserted in its place
</verb>
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 <bf>cd {Linux Quake directory}</bf>, and have this as their
current directory.

<sect> General Info <p>

<sect1> Getting Started <p>

Installing Quake requires a few basic steps.

<descrip>

<tag/Get the Game Data Files/

Getting the game data files is normally done by installing the game (or
<url url="ftp://ftp.idsoftware.com/idstuff/quake/quake106.zip" name="game demo">) using
Microsoft Windows, or an emulator such as Wine or Dosbox, and then
copying the <bf>id1</bf> directory of the installed game to your Linux Quake
directory - making sure all files are in <ref id="lowercase_" name="lowercase">.

Alternatively, you can use the
<url url="http://freshmeat.net/projects/lhaforunix/" name="lha utility">
to extract the data files.  For early CDs, you must first
<code>    cat /mnt/cdrom/quake101.1 /mnt/cdrom/quake101.2 > resource.1</code>
Once you have the resource.1 file, then type
<code>
    cd /usr/local/games/quake
    lha e {some directory}/resource.1
</code>

Later versions of the game, including WinQuake, come with the data files in an
uncompressed form and the <bf>id1</bf> directory can be directly copied from
the CD.  


<tag/Install a Quake Executable/

The program you execute to run Quake is known as the <ref id="engine_"
name="game engine">.
There are several to choose from, but the simplest choice is either the author's
<url url="http://prdownloads.sourceforge.net/uhexen2/tyrquake-sa-0.54.tgz?download" name="patched TyrQuake">,
or J<>rgen's <ref id="glquake_" name="GLQuake">.  After downloading or compiling
a game engine, place this binary in your Quake directory alongside the
<bf>id1</bf> directory.

<tag/Summary/

Finally, you should have a directory structure similar to this, with all files
being in <ref id="lowercase_" name="lowercase">:

<verb>
/usr/local/games/quake +- glquake.glx (or another game engine)
                       |
                       +- id1 -+- config.cfg
                               |
                               +- game.dat
                               |
                               +- pak0.pak
                               |
                               +- pak1.pak
</verb>
Now, from an xterm window, type (for example)
<code>    ./glquake.glx -fullscreen -width 800 -height 600</code>
to start the game.


<tag/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:

</itemize>

</descrip>

<sect1> Command Line Options <p>

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:

<descrip>
	<tag/-window/Run the game in windowed mode
	<tag/-fullscreen/Run the game in fullscreen mode
	<tag/-game NAME/Load the mod NAME.
	<tag/-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.
	<tag/-width WIDTH/window/fullscreen width
	<tag/-height HEIGHT/window/fullscreen height
	<tag/-basedir DIRECTORY/Use this directory by default
	<tag/-sndspeed MHz/Set sound sampling rate (eg. 44100, 22050, 11025)
	<tag/-sndbits N/Set sound bits to N = 8 or 16
	<tag/-nosound/Disable sound. Necessary when sound is
	absent/unconfigured to stop the game from crashing.
	<tag/-nomtex/Disable GL multitextures.
	<tag/-listen N/Allow a maximum of N players/bots to join multiplayer games.
	<tag/-cddev DEVICE/Use DEVICE for playing the cd music
	<tag/-nocdaudio/Disable cd audio
</descrip>
	
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
<code>    glquake.glx +skill 2 +map e1m1</code>

<sect1> Game Console Commands <p>

<em>For more info see <url url="http://www.planetquake.com/console/commands/quake.html"></em>

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 "&tilde;" key when
in a game. The main commands include -

<descrip>

<tag/god/Invulnerability
<tag/noclip/Walk through walls
<tag/notarget/Enemies won't attack player
<tag/timedemo DEMO/Play DEMO (eg. "demo1") at top speed and show frame rate
<tag/impulse N/Issue "impulse N" 

These are in-game commands which can be given special uses. The most 
common cheat is <bf>impulse  9</bf> which gives all weapons.
<tag/bind key "COMMAND"/Bind a key to perform a command
<tag/map MAP/Load MAP
<tag/changelevel MAP/Load MAP without resetting player settings
<tag/quit/Exit to system
<tag/skill	VALUE/value = 0 (easy) - 3 (impossible)

Degree of difficulty. Level must be restarted to take effect

<tag/r_wateralpha	VALUE/value = 0.0 - 1.0

Opacity of water in maps with transparent water support (See <ref id="watervis_" name="Watervis">)

<tag/_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

<tag/gl_texturemode	VALUE/value = gl_nearest | gl_nearest_mipmap_nearest | gl_linear_mipmap_nearest | gl_linear_mipmap_linear

Worst to best texture quality.

<tag/r_shadows	FLAG/flag = 0 | 1

Display model shadows

<tag/vid_wait	FLAG/flag = 0 | 1

Sync video output with screen refresh

<tag/chase_active	FLAG/flag = 0 | 1

Show player from third person perspective

</descrip>

<sect> Game Engines <label id="engine_"> <p>

<label id="tyrquake_">

<sect1> TyrQuake <p>

TyrQuake is a fairly complete project including OpenGL, Software Quake and QuakeWorld 
clients, and <url url="http://disenchant.net/utils.html" name="other tools">
 including the popular TyrLite. Tyrann's focus is on a fully featured
but minimalist engine for Windows and Linux. 
A new feature is command line completion. Pressing the <bf>tab</bf> key
at the console will automatically complete the current command or mapname - similar to the Linux shell, Bash.

Currently at version 0.54, TyrQuake now compiles out of the box on all systems I've tested :-)
<newline>
Typing <bf>make</bf> will build all the clients, but to compile only
the single player client, after unpacking the source code, type:
<verb>
make prepare
make tyr-glquake
</verb>
Alternatively, for a more verbose make process, use:
<verb>
make tyr-glquake V=1
</verb>


A patched TyrQuake binary is available
<url url="http://prdownloads.sourceforge.net/uhexen2/tyrquake-sa-0.54.tgz?download" name="here">.

<url url="http://disenchant.net/engine.html">

<label id="darkplaces_">

<sect1> Darkplaces <p>

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 <ref id="nehahra_"
name="Nehahra"> and <ref id="nexuiz_" name="Nexuiz">, and has improved support
for the official mission packs.

Havoc's <url url="http://icculus.org/twilight/darkplaces/files/" name="file
archive"> 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
<bf>make</bf> to see a list of possible targets (programs), and select one.
For example - to build the OpenGL engine with ALSA sound type <bf>make
cl-release</bf>, or to build with OSS sound, <bf>make cl-release
DP_SOUND_API=OSS</bf>.

Much thanks to Lord Havoc for this great project.

<url url="http://www.icculus.org/twilight/darkplaces">

<label id="qudos_">

<sect1> QuDos Quake Ports <p>

"Here you'll find QuDos' `linuxified` src+bin tarballs for popular quake ports,
including that of bjp for Nehahra."

This is great news for gamers. For the first time these engines - including
DemonQuake, JoeQuake, NehQuake, Qrack and Tremor - have been ported to Linux.
<url url="http://qudos.quakedev.com/linux/quake1/NehQuake-bjp-bin-src.linux.tar.bz2"
name="NehQuake"> runs <ref id="nehahra_" name="Nehahra"> much faster than
Darkplaces, and <url url="http://qudos.quakedev.com/linux/quake1/JoeQuake-v0.15b1146-bin-src.linux.tar.bz2" name="JoeQuake"> has impressive eye candy.

The tarballs include source code, binaries and in most cases the data
files necessary for the engine.  To install these data files, find the simply
named folders (such as "joequake" or "qrack") inside the tarballs and move them
to your quake directory. If they are not present you will have to download them
from the game's homepage.

For some of the engines, an additional sound library (which is included)
has to be installed. To do this:
<code>
    su
    cd /usr/lib
    mv {some directory}/libfmod-3.74.1.so .
    ln -s libfmod-3.74.1.so libfmod.so
    ldconfig
</code>
or visit the <url url="http://www.fmod.org" name="FMOD homepage"> and install the
libraries manually.

<url url="http://qudos.quakedev.com/linux/quake1">

<sect1> MFCN's GLQuake <label id="glquake_"> <p>

A great place for Linux noobs to go is J<>rgen's no frills site. 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.

<url url="http://mfcn.ilo.de/glxquake">

<sect1> Tenebrae <p>

A Quake engine using lighting techniques similar to those in Doom III. Tenebrae
requires a very fast computer and may not be compatible with all
hardware (the documentation is a little unclear, and ATI cards may not work).
This game only ran at 10 to 50 fps on my Celeron 2400 / FX5600. 
Interestingly, Tenebrae has an "easter egg". To see this, in the quit game
dialog press "d". Also check out the "bumptest" and "zoo" maps.

The Tenebrae <url url="http://www.liflg.org/?what=dl&amp;catid=6&amp;gameid=12&amp;filename=tenebrae.quake_1.04-english-2.run" name="installer">
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). Tenebrae binaries may be available
<url url="http://www.cynapses.org/tmp/tenebrae/" name="here">.

Compilation of the source code may not be straight forward. Firstly:
<verb>
cd linux ; ln -s Makefile.i386linux Makefile ; make
</verb>
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:
<verb>
- extern int gethostname (char *, int);
+ extern int gethostname (char *, size_t);
</verb>

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:
<bf>tenebrae.run -basedir $PWD</bf>.
Alternatively you can start a new X session with the command:
<verb>
startx $PWD/tenebrae.run -basedir $PWD -- :1 -depth 24
</verb>

<label id="quakeforge_">

<sect1> QuakeForge <p>

QF is a comprehensive Linux Quake project. It has elegant graphical enhancements,
numerous single player and <ref id="quakeworld_" name="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
<bf>ln -s /usr/local/games/quake/id1 /usr/local/share/games/quakeforge/id1</bf>).

For information about building QuakeForge on the BSD Unices, see the <ref
id="freebsd_" name="FreeBSD"> section.

Kudos to the QuakeForge team for a huge project which has provided much inspiration
for other open source games.

<label id="nprquake_">

<sect1> NPRQuake <p>

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 <url
url="http://www.geocities.com/coolguywithgun" name="linux port"> includes
support for the cartoon renderer <url
url="http://www.cs.unc.edu/%7Eadyilie/comp238/Final/Final.htm"
name="ainpr">, and works really well for me.

The <url url="http://www.tempestgames.com/ryan/" name="SDL version">
has rewritten mouse and video code and may work on otherwise troublesome
systems. But the sound APIs have not been ported to SDL, so it
is not a fully portable engine.

<url url="http://www.cs.wisc.edu/graphics/Gallery/NPRQuake/">

<sect1> Twilight Project <p>

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 &tilde;quick&tilde;, 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:
<verb>
-               if (progs->ofs_strings + pr_stringssize >= com_filesize)
+               if (progs->ofs_strings + pr_stringssize >= (uint)com_filesize)
</verb>
Executing <bf>scons.py</bf> will now (hopefully) build the binaries, and after copying the single
player client (twilight-nq) to your quake directory,
type <bf>twilight-nq -basedir $PWD</bf> 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.

<url url="http://icculus.org/twilight">

<label id="sdlquake_">
<sect1> SDL Quake <p>

This basic version of Quake is not of major interest to Linux users. It's main
feature is that it uses 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 cdrom will limit the game's speed. To avoid this simply remove
the CD from the drive, or use the <bf>-nocdaudio</bf> option.

The game runs at a fixed resolution - the width and height can't be changed.
To play in fullscreen mode, use the <bf>-fullscreen</bf> option.

<url url="http://www.libsdl.org/projects/quake">

<sect1> wmQuake <p>

WindowMaker is a window manager for X11, and this tiny version of Quake
fits in an 64x64 pixel dockable applet!
<newline>
You can test it out if you don't have WindowMaker, but the game will crash if it gets keyboard focus.
<newline><newline>
For the curious, this game can  be benchmarked with <bf>timedemo demo1</bf> after removing the "usleep" commands from
sys_linux.c.

<url url="http://freshmeat.net/projects/wmquake/">

<sect1> Software Quake <p>

<em>For a more in-depth treatment of Software Quake, see the  <ref id="other_" name="previous version"> of this how-to</em>.

The <url url="http://www.quakeforge.net/files/q1source.zip" name="original
WinQuake source"> also came with two pixelated versions of the game:

<itemize>
<item> X Quake (quake.x11)
<item> Svga Quake (squake)
</itemize>
		
but compiling them is no longer straight forward. It involves copying
<bf>Makefile.linux</bf> to <bf>Makefile</bf>, editing this file to remove the extra
targets , replacing <bf>/usr/X11/lib</bf> with <bf>/usr/X11R6/lib</bf> and typing
<bf>make build_release</bf>.

There are easier options though. <ref id="tyrquake_" name="TyrQuake">
and <ref id="quakeforge_" name="QuakeForge"> have software clients, and there is
also an old <ref id="sdlquake_" name="SDL Quake">
written by SDL's author, Sam Lantinga, which should work on all modern platforms.

<sect> Mods

<sect1> Mods <p>

There are hundreds of user created levels - known variously as "mods", "total
conversions" or simply "maps", all over the internet. When it comes to
finding them though, many URLs are no longer valid, and it is easier to just
google for a file name (perhaps adding "quake" as an extra search term) than
to try and find the project's homepage - which is probably just dust in the
ether now.

To run new maps, place the bsp file into the "quake/id1/maps"
subdirectory, and start Quake with the <bf>+map MAPNAME</bf> 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 <bf>-game DIR</bf> command line option and,
sometimes, <bf>+map MAPNAME</bf> where MAPNAME is the mod's start map. 

For both maps and mods, all files should be in <ref id="lowercase_" name="lowercase"> format.


Mod lists can be found at <url url="http://www.quaketerminus.com/addon.htm"
name="QuakeTerminus"> and
UnderWorld  (<url url="http://www.planetquake.com/underworld/qclassics.html" name="Hall of Fame">, <url url="http://www.planetquake.com/underworld/q1sprecommended.html" name="Recommended">).
At the DoomWadStation you'll find a comprehensive <url url="http://www.doomwadstation.com/idgames/index.php?dir=Quake%2F" name="archive"> of Quake levels.

A few of the author's favourites are:

<descrip>

<tag/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.
<url url="http://www.planetquake.com/tronyn/soul" name="Link">

<label id="nehahra_"><tag/Nehahra/
Epic. Ambitious. Otherwordly.
Nehahra is the definitive Quake mod, supported in Linux by LordHavoc's
<ref id="darkplaces_" name="Darkplaces">, and <ref id="qudos_" name="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 <bf>nomonsters 1</bf> at the game console.

<url url="http://www.planetquake.com/nehahra" name="Link">

<tag/Contract Revoked/
A modern mod which made my jaw drop. It also has ambitious sequels: The Lost
Chapters and Quoth.

<tag/Zerst<73>rer/
Dark and bloody, with Doom's paranoiac atmosphere - a classic.
Zerst<EFBFBD>rer also has some good death match levels -

<tag/The Hunted Chronicles/
Another game requiring the Darkplaces engine, the Hunted Chronicles is a 
zombie shooter/survival mod in two parts. The second uses fog

Half-Life mod.
<url url="http://www.ru1337.com/" name="Link">

<tag/Blood Mage/

finished.  (The project ended prematurely when the web hosting hit a snag).
Not all the player classes work perfectly. Use the "g" key twice to purchase
items, the "<",">","/" keys for inventory, and the "w","e","r" keys for the

Another first for Quake was the implementation of it's own game language -
Quake C.  This enables mods to work seamlessly on any operating system.
It is possible to install many of the editors which are used to make Quake

<sect1> Digital Paint 2 <p>

Paintball comes to Linux !

Digital Paint 2 is an "original" multiplayer game based on the
<ref id="quakeII_" name="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 ;->.

Single player games are possible by playing against computer bots.

<label id="proquake_">

<sect1> ProQuake <p>

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."

<label id="lowercase_"><bf>Files not lowercased</bf> or <bf>Data files missing</bf>.

Linux Quake requires (most) filenames to be in lowercase.  If you get an error
similar to "<bf>Error: W_LoadWadFile: couldn't load gfx.wad</bf>" it means the game

the game will disable hardware dga mouse.

<newline><newline>

</itemize>

<tag/Game saves fail &sol; 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:

<itemize>

<item> Run the game as super user: Type <bf>su</bf> and enter root's
password before typing <bf>glquake.glx ...</bf> to start the game.

<newline><newline>

<item> 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):
<bf>chown -R USERNAME /usr/local/games/quake</bf>. However it is
recommended users read the <bf>chmod</bf> and <bf>chown</bf> man
and info pages to better understand Unix file permissions.

<newline><newline>

<item> In full multi-user environments it is recommended using the
<ref id="darkplaces_" name="Darkplaces"> or 
<ref id="quakeforge_" name="QuakeForge"> game engines, which correctly
place per-user data in their home directory.

</itemize>

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 %-/.

<tag/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.

<tag/Lines on screen/
A common problem with 3dfx cards is a shower of flickering lines on the screen.
		
<itemize>

<item> From the game console, type <bf>gl_ztrick 0</bf>.

</itemize>

<tag/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 <bf>-nomtex</bf> option.

Older video cards may occasionally draw models in all white.

<sect1> Video Drivers <p>

Setting up hardware GL acceleration under Linux used to be a big deal, but
modern distros should now handle this automatically. Of course there are
exceptions...

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 <url
url="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.

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.
<url url="http://sourceforge.net/docman/display_doc.php?docid=28982&amp;group_id=124987" name="Here">

<sect1> Sound Drivers <label id="sound_"> <p>

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 <bf>lsmod</bf> 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
<url url="http://www.alsa-project.org" name="Alsa Homepage">
and Linux Journal's
<url url="http://www.linuxjournal.com/node/8234/print" name="Guide to ALSA">.

For those already with ALSA wishing to try the OSS modules, a

is probably necessary.

<sect1> Quake II <label id="quakeII_"> <p>

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.

<url url="http://qudos.quakedev.com/linux/quake2" name="QuDos' Quake II">
is the most notable. It is based on 
<url url="http://www.icculus.org/quake2/" name="Icculus Quake II">,

hardware specs: A 2GHz cpu and 512meg ram are the official minimum
requirements.  It's a beautiful game which should really be played with the

<sect1> Transparent Water and Vispatch <p>

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 <bf>r_wateralpha</bf> &lt; 1.0, issuing the
console command <bf>r_novis 1</bf> 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

as well as the 
<url url="http://www.3ddownloads.com/telefragged/inside3d/qip/watervis" name="vispatch data files">
for the game you are patching.

Vispatch was originally written by Andy Bay but has not had much support since

<sect1> Miscellaneous <p>

<itemize>

	<item> Because of the way the original game renders the sky, any map with
	numerous outdoor enemies suffers a big performance hit.

<newline><newline>

	<item> You can jump further when strafing than when going forward or back 8-)

<newline><newline>

	<item> The <bf>timedemo demo1</bf> command is a great way to benchmark your system.

<newline><newline>

	<item> 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.

<newline><newline>

	<item> 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.

<sect1> Quotes <p>

<itemize>

	<item> John Carmack -
	<newline>
	"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"

<newline><newline>

	<item> From the original Quake How-To -
	<newline>
	"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."

<newline><newline>

	<item> Func Message Board -
	<newline> "... This Will Produce A Fully Functional Bouncing, Exploding Zombie."
	<newline> Sounds like fun :) 

<newline><newline>

	<item> Quake Wikipedia -
	<newline>"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."

<newline><newline>

	<item> Moby Games 
	<newline> (by  Pathogen) <newline> 
	"... 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."
	<newline> (by Ashley Pomeroy) <newline>
	"Almost incidentally, Quake introduced the now-standard concept of a FPS
	'console', and popularised 'mouselook' as *the* absolute standard
	control interface.  Although the specifications required a Pentium,
	Quake ran acceptably well on a 486 DX4/100"

	<item> Slashdot Tenebrae Forum -
<verb>
... 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!"

<sect1> Glossary <p>

<descrip>

<tag/ALSA/ <url url="http://www.alsa-project.org" name="Advanced Linux Sound Architecture">.

<tag/API/Application Program Interface. The computer libraries
which are used when programming, and link the game to the hardware.

<tag/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.

<tag/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.

<tag/FPS/First Person Shooter. A shooting game viewed from the "first person" perspective.

<tag/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.

<tag/Noob/Newbie. Someone new to a computer related topic.

<tag/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 <bf>patch [--dry-run] -pNUM
&lt;FILE </bf> 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 <bf>control-C</bf> character.

Of course you could always type <bf>man patch</bf> and learn for yourself
how to use this powerful unix command. ;-/

<tag/SDL/<url url="http://www.libsdl.org/" name="Simple DirectMedia Layer">
cross platform hardware API widely used in Linux games.

<tag/Server/A program central to multiplayer games to which every player connects.

<tag/Tarball/An archive file such as <bf>somefile.tar</bf> 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
<bf>.gz</bf> or <bf>.bz2</bf>. The extension <bf>.tar.gz</bf>
is often shortened to <bf>.tgz</bf>.
