The map editor and associated compiling tools are not included. We suggest you
|
|
|
|
use a modern copy from http://www.qeradiant.com/.
|
|
|
|
|
|
|
|
The original id software readme that accompanied the Q3 source release has been
|
|
|
|
renamed to id-readme.txt so as to prevent confusion. Please refer to the
|
|
|
|
web-site for updated status.

--------------------------------------------- Compilation and installation -----
|
|
|
|
|
|
|
|
For *nix
|
|
|
|
1. Change to the directory containing this readme.
|
|
|
|
2. Run 'make'.
|
|
|
|
|
2009-04-13 02:04:26 +00:00
|
|
|
For Windows,
|
|
|
|
1. Please refer to the excellent instructions here:
|
|
|
|
http://wiki.ioquake3.org/Building_ioquake3

|
|
|
|
|
For Mac OS X, building a Universal Binary
|
2007-12-31 03:47:36 +00:00
|
|
|
1. Install MacOSX SDK packages from XCode. For maximum compatibility,
|
2008-01-03 20:27:46 +00:00
|
|
|
install MacOSX10.4u.sdk and MacOSX10.3.9.sdk, and MacOSX10.2.8.sdk.
|
2006-11-09 14:51:24 +00:00
|
|
|
2. Change to the directory containing this README file.
|
|
|
|
3. Run './make-macosx-ub.sh'
|
2007-08-23 17:23:15 +00:00
|
|
|
4. Copy the resulting ioquake3.app in /build/release-darwin-ub to your
|
2006-11-09 14:51:24 +00:00
|
|
|
/Applications/ioquake3 folder.
|
|
|
|
|
|
|
|
Installation, for *nix
|
|
|
|
1. Set the COPYDIR variable in the shell to be where you installed Quake 3
|
2007-09-05 18:17:46 +00:00
|
|
|
to. By default it will be /usr/local/games/quake3 if you haven't set it.
|
2006-11-09 14:51:24 +00:00
|
|
|
This is the path as used by the original Linux Q3 installer and subsequent
|
|
|
|
point releases.
|
|
|
|
2. Run 'make copyfiles'.
|
|
|
|
|
|
|
|
It is also possible to cross compile for Windows under *nix using MinGW. A
|
|
|
|
script is available to build a cross compilation environment from
|
|
|
|
http://www.libsdl.org/extras/win32/cross/build-cross.sh. The gcc/binutils
|
2007-05-29 19:22:24 +00:00
|
|
|
version numbers that the script downloads may need to be altered.
|
|
|
|
Alternatively, your distribution may have mingw32 packages available. On
|
|
|
|
debian/Ubuntu, these are mingw32, mingw32-runtime and mingw32-binutils. Cross
|
|
|
|
compiling is simply a case of using './cross-make-mingw.sh' in place of 'make',
|
|
|
|
though you may find you need to change the value of the variables in this
|
|
|
|
script to match your environment.

Using shared libraries instead of qvm
|
|
|
|
To force Q3 to use shared libraries instead of qvms run it with the following
|
|
|
|
parameters: +set sv_pure 0 +set vm_cgame 0 +set vm_game 0 +set vm_ui 0
|
|
|
|
|
|
|
|
Using Demo Data Files
|
|
|
|
Copy demoq3/pak0.pk3 from the demo installer to your baseq3 directory. The
|
|
|
|
qvm files in this pak0.pk3 will not work, so you have to use the native
|
|
|
|
shared libraries or qvms from this project. To use the new qvms, they must be
|
|
|
|
put into a pk3 file. A pk3 file is just a zip file, so any compression tool
|
|
|
|
that can create such files will work. The shared libraries should already be
|
|
|
|
in the correct place. Use the instructions above to use them.
|
|
|
|
|
|
|
|
Please bear in mind that you will not be able to play online using the demo
|
|
|
|
data, nor is it something that we like to spend much time maintaining or
|
|
|
|
supporting.

Help! Ioquake3 won't give me an fps of X anymore when setting com_maxfps!
|
|
|
|
Ioquake3 now uses the select() system call to wait for the rendering of the
|
|
|
|
next frame when com_maxfps was hit. This will improve your CPU load
|
|
|
|
considerably in these cases. However, not all systems may support a
|
|
|
|
granularity for its timing functions that is required to perform this waiting
|
|
|
|
correctly. For instance, ioquake3 tells select() to wait 2 milliseconds, but
|
|
|
|
really it can only wait for a multiple of 5ms, i.e. 5, 10, 15, 20... ms.
|
|
|
|
In this case you can always revert back to the old behaviour by setting the
|
|
|
|
cvar com_busyWait to 1.
|
|
|
|
|
2011-04-27 16:04:23 +00:00
|
|
|
Using HTTP/FTP Download Support (Server)
|
|
|
|
You can enable redirected downloads on your server even if it's not
|
|
|
|
an ioquake3 server. You simply need to use the 'sets' command to put
|
|
|
|
the sv_dlURL cvar into your SERVERINFO string and ensure sv_allowDownloads
|
|
|
|
is set to 1
|
|
|
|
|
|
|
|
sv_dlURL is the base of the URL that contains your custom .pk3 files
|
|
|
|
the client will append both fs_game and the filename to the end of
|
|
|
|
this value. For example, if you have sv_dlURL set to
|
|
|
|
"http://ioquake3.org", fs_game is "baseq3", and the client is
|
|
|
|
missing "test.pk3", it will attempt to download from the URL
|
|
|
|
"http://ioquake3.org/baseq3/test.pk3"
|
|
|
|
|
|
|
|
sv_allowDownload's value is now a bitmask made up of the following
|
|
|
|
flags:
|
|
|
|
1 - ENABLE
|
|
|
|
4 - do not use UDP downloads
|
|
|
|
8 - do not ask the client to disconnect when using HTTP/FTP
|
|
|
|
|
|
|
|
Server operators who are concerned about potential "leeching" from their
|
|
|
|
HTTP servers from other ioquake3 servers can make use of the HTTP_REFERER
|
|
|
|
that ioquake3 sets which is "ioQ3://{SERVER_IP}:{SERVER_PORT}". For,
|
|
|
|
example, Apache's mod_rewrite can restrict access based on HTTP_REFERER.
|
|
|
|
|
|
|
|
Using HTTP/FTP Download Support (Client)
|
|
|
|
Simply setting cl_allowDownload to 1 will enable HTTP/FTP downloads
|
|
|
|
assuming ioquake3 was compiled with USE_CURL=1 (the default).
|
|
|
|
like sv_allowDownload, cl_allowDownload also uses a bitmask value
|
|
|
|
supporting the following flags:
|
|
|
|
1 - ENABLE
|
|
|
|
2 - do not use HTTP/FTP downloads
|
|
|
|
4 - do not use UDP downloads
|
|
|
|
|
|
|
|
When ioquake3 is built with USE_CURL_DLOPEN=1 (default on some platforms),
|
|
|
|
it will use the value of the cvar cl_cURLLib as the filename of the cURL
|
|
|
|
library to dynamically load.
|
|
|
|
|
|
|
|
Multiuser Support on Windows systems
|
|
|
|
On Windows, all user specific files such as autogenerated configuration,
|
|
|
|
demos, videos, screenshots, and autodownloaded pk3s are now saved in a
|
|
|
|
directory specific to the user who is running ioquake3.
|
|
|
|
|
|
|
|
On NT-based such as Windows XP, this is usually a directory named:
|
|
|
|
"C:\Documents and Settings\%USERNAME%\Application Data\Quake3\"
|
|
|
|
|
|
|
|
Windows 95, Windows 98, and Windows ME will use a directory like:
|
|
|
|
"C:\Windows\Application Data\Quake3"
|
|
|
|
in single-user mode, or:
|
|
|
|
"C:\Windows\Profiles\%USERNAME%\Application Data\Quake3"
|
|
|
|
if multiple logins have been enabled.
|
|
|
|
|
|
|
|
In order to access this directory more easily, the installer may create a
|
|
|
|
Shortcut which has its target set to:
|
|
|
|
"%APPDATA%\Quake3\"
|
|
|
|
This Shortcut would work for all users on the system regardless of the
|
|
|
|
locale settings. Unfortunately, this environment variable is only
|
|
|
|
present on Windows NT based systems.
|
|
|
|
|
|
|
|
You can revert to the old single-user behaviour by setting the fs_homepath
|
|
|
|
cvar to the directory where ioquake3 is installed. For example:
|
|
|
|
ioquake3.exe +set fs_homepath "c:\ioquake3"
|
|
|
|
Note that this cvar MUST be set as a command line parameter.
|
|
|
|
|
|
|
|
SDL Keyboard Differences
|
|
|
|
ioquake3 clients have different keyboard behaviour compared to the original
|
|
|
|
Quake3 clients.
|
|
|
|
|
|
|
|
* "Caps Lock" and "Num Lock" can not be used as normal binds since they
|
|
|
|
do not send a KEYUP event until the key is pressed again.
|
|
|
|
|
|
|
|
* SDL > 1.2.9 does not support disabling dead key recognition. In order to
|
|
|
|
send dead key characters (e.g. ~, ', `, and ^), you must key a Space (or
|
|
|
|
sometimes the same character again) after the character to send it on
|
|
|
|
many international keyboard layouts.
|
|
|
|
|
|
|
|
* The SDL client supports many more keys than the original Quake3 client.
|
|
|
|
For example the keys: "Windows", "SysReq", "ScrollLock", and "Break".
|
|
|
|
For non-US keyboards, all of the so called "World" keys are now supported
|
|
|
|
as well as F13, F14, F15, and the country-specific mode/meta keys.
|
|
|
|
|
|
|
|
On many international layouts the default console toggle keys are also dead
|
|
|
|
keys, meaning that dropping the console potentially results in
|
|
|
|
unintentionally initiating the keying of a dead key. Futhermore SDL 1.2's
|
|
|
|
dead key support is broken by design and Q3 doesn't support non-ASCII text
|
|
|
|
entry, so the chances are you won't get the correct character anyway.
|
|
|
|
|
|
|
|
If you use such a keyboard layout, you can set the cvar cl_consoleKeys. This
|
|
|
|
is a space delimited list of key names that will toggle the console. The key
|
|
|
|
names are the usual Q3 names e.g. "~", "`", "c", "BACKSPACE", "PAUSE",
|
|
|
|
"WINDOWS" etc. It's also possible to use ASCII characters, by hexadecimal
|
|
|
|
number. Some example values for cl_consoleKeys:
|
|
|
|
|
|
|
|
"~ ` 0x7e 0x60" Toggle on ~ or ` (the default)
|
|
|
|
"WINDOWS" Toggle on the Windows key
|
|
|
|
"c" Toggle on the c key
|
|
|
|
"0x43" Toggle on the C character (Shift-c)
|
|
|
|
"PAUSE F1 PGUP" Toggle on the Pause, F1 or Page Up keys
|
|
|
|
|
|
|
|
Note that when you elect a set of console keys or characters, they cannot
|
|
|
|
then be used for binding, nor will they generate characters when entering
|
|
|
|
text. Also, in addition to the nominated console keys, Shift-ESC is hard
|
|
|
|
coded to always toggle the console.

QuakeLive mouse acceleration (patch and this text written by TTimo from id)
|
|
|
|
I've been using an experimental mouse acceleration code for a while, and
|
|
|
|
decided to make it available to everyone. Don't be too worried if you don't
|
|
|
|
understand the explanations below, this is mostly intended for advanced
|
|
|
|
players:
|
|
|
|
To enable it, set cl_mouseAccelStyle 1 (0 is the default/legacy behavior)
|
|
|
|
|
|
|
|
New style is controlled with 3 cvars:
|
|
|
|
|
|
|
|
sensitivity
|
|
|
|
cl_mouseAccel
|
|
|
|
cl_mouseAccelOffset
|
|
|
|
|
|
|
|
The old code (cl_mouseAccelStyle 0) can be difficult to calibrate because if
|
|
|
|
you have a base sensitivity setup, as soon as you set a non zero acceleration
|
|
|
|
your base sensitivity at low speeds will change as well. The other problem
|
|
|
|
with style 0 is that you are stuck on a square (power of two) acceleration
|
|
|
|
curve.
|
|
|
|
|
|
|
|
The new code tries to solve both problems:
|
|
|
|
|
|
|
|
Once you setup your sensitivity to feel comfortable and accurate enough for
|
|
|
|
low mouse deltas with no acceleration (cl_mouseAccel 0), you can start
|
|
|
|
increasing cl_mouseAccel and tweaking cl_mouseAccelOffset to get the
|
|
|
|
amplification you want for high deltas with little effect on low mouse deltas.
|
|
|
|
|
|
|
|
cl_mouseAccel is a power value. Should be >= 1, 2 will be the same power curve
|
|
|
|
as style 0. The higher the value, the faster the amplification grows with the
|
|
|
|
mouse delta.
|
|
|
|
|
|
|
|
cl_mouseAccelOffset sets how much base mouse delta will be doubled by
|
|
|
|
acceleration. The closer to zero you bring it, the more acceleration will
|
|
|
|
happen at low speeds. This is also very useful if you are changing to a new
|
|
|
|
mouse with higher dpi, if you go from 500 to 1000 dpi, you can divide your
|
|
|
|
cl_mouseAccelOffset by two to keep the same overall 'feel' (you will likely
|
|
|
|
gain in precision when you do that, but that is not related to mouse
|
|
|
|
acceleration).
|
|
|
|
|
|
|
|
Mouse acceleration is tricky to configure, and when you do you'll have to
|
|
|
|
re-learn your aiming. But you will find that it's very much forth it in the
|
|
|
|
long run.
|
|
|
|
|
|
|
|
If you try the new acceleration code and start using it, I'd be very
|
|
|
|
interested by your feedback.

64bit mods
|
|
|
|
If you wish to compile external mods as shared libraries on a 64bit platform,
|
|
|
|
and the mod source is derived from the id Q3 SDK, you will need to modify the
|
|
|
|
interface code a little. Open the files ending in _syscalls.c and change
|
|
|
|
every instance of int to intptr_t in the declaration of the syscall function
|
|
|
|
pointer and the dllEntry function. Also find the vmMain function for each
|
|
|
|
module (usually in cg_main.c g_main.c etc.) and similarly replace the return
|
|
|
|
value in the prototype with intptr_t (arg0, arg1, ...stay int).
|
|
|
|
|
|
|
|
Add the following code snippet to q_shared.h:
|
|
|
|
|
|
|
|
#ifdef Q3_VM
|
|
|
|
typedef int intptr_t;
|
|
|
|
#else
|
|
|
|
#include <stdint.h>
|
|
|
|
#endif
|
|
|
|
|
|
|
|
Note if you simply wish to run mods on a 64bit platform you do not need to
|
|
|
|
recompile anything since by default Q3 uses a virtual machine system.
|
|
|
|
|
|
|
|
Creating mods compatible with Q3 1.32b
|
|
|
|
If you're using this package to create mods for the last official release of
|
|
|
|
Q3, it is necessary to pass the commandline option '-vq3' to your invocation
|
|
|
|
of q3asm. This is because by default q3asm outputs an updated qvm format that
|
|
|
|
is necessary to fix a bug involving the optimizing pass of the x86 vm JIT
|
2008-04-10 16:21:49 +00:00
|
|
|
compiler.
|
|
|
|
|
|
|
|
Creating standalone games
|
|
|
|
Have you finished the daunting task of removing all dependencies on the Q3
|
|
|
|
game data? You probably now want to give your users the opportunity to play
|
|
|
|
the game without owning a copy of Q3, which consequently means removing cd-key
|
|
|
|
and authentication server checks. In addition to being a straightforward Q3
|
|
|
|
client, ioquake3 also purports to be a reliable and stable code base on which
|
|
|
|
to base your game project.
|
|
|
|
|
2008-04-10 15:37:25 +00:00
|
|
|
However, before you start compiling your own version of ioquake3, you have to
|
2008-04-10 16:21:49 +00:00
|
|
|
ask yourself: Have we changed or will we need to change anything of importance
|
|
|
|
in the engine?
|
|
|
|
|
|
|
|
If your answer to this question is "no", it probably makes no sense to build
|
|
|
|
your own binaries. Instead, you can just use the pre-built binaries on the
|
|
|
|
website. Just make sure the game is called with:
|
|
|
|
|
2011-02-04 12:04:56 +00:00
|
|
|
+set com_basegame <yournewbase>
|
|
|
|
|
|
|
|
in any links/scripts you install for your users to start the game. The
|
|
|
|
binary must not detect any original quake3 game pak files. If this
|
|
|
|
condition is met, the game will set com_standalone to 1 and is then running
|
|
|
|
in stand alone mode.
|
|
|
|
|
|
|
|
If you want the engine to use a different directory in your homepath than
|
|
|
|
e.g. "Quake3" on Windows or ".q3a" on Linux, then set a new name at startup
|
|
|
|
by adding
|
|
|
|
|
|
|
|
+set com_homepath <homedirname>
|
|
|
|
|
2011-04-27 16:04:23 +00:00
|
|
|
to the command line. You can also control which kind of messages to send to
|
2011-02-04 13:25:51 +00:00
|
|
|
the master server:
|
|
|
|
|
|
|
|
+set sv_heartbeat <heartbeat> +set sv_flatline <flatline>
|
|
|
|
+set cl_gamename <gamename>
|
|
|
|
|
|
|
|
The <heartbeat> and <flatline> message can be specific to your game. The
|
|
|
|
flatline message is sent to signal the master server that the game server is
|
|
|
|
quitting. Vanilla quake3 uses "QuakeArena-1" both for the heartbeat and
|
|
|
|
flatline messages.
|
|
|
|
The cl_gamename message is for dpmaster to specify which game the client
|
|
|
|
wants a server list for. It is only used in the new ipv6 based getServersExt
|
|
|
|
query.
|
|
|
|
|
|
|
|
Example line:
|
2011-02-04 12:04:56 +00:00
|
|
|
|
|
|
|
+set com_basegame basefoo +set com_homepath .foo
|
2011-02-04 13:25:51 +00:00
|
|
|
+set sv_heartbeat fooalive +set sv_flatline foodead
|
|
|
|
+set cl_gamename foo
|
|
|
|
|
2008-04-10 15:37:25 +00:00
|
|
|
|
2008-04-10 16:21:49 +00:00
|
|
|
If you really changed parts that would make vanilla ioquake3 incompatible with
|
|
|
|
your mod, we have included another way to conveniently build a stand-alone
|
|
|
|
binary. Just run make with the option BUILD_STANDALONE=1. Don't forget to edit
|
|
|
|
the PRODUCT_NAME and subsequent #defines in qcommon/q_shared.h with
|
|
|
|
information appropriate for your project.
|
|
|
|
|
|
|
|
While a lot of work has been put into ioquake3 that you can benefit from free
|
|
|
|
of charge, it does not mean that you have no obligations to fulfil. Please be
|
|
|
|
aware that as soon as you start distributing your game with an engine based on
|
|
|
|
our sources we expect you to fully comply with the requirements as stated in
|
|
|
|
the GPL. That includes making sources and modifications you made to the
|
|
|
|
ioquake3 engine as well as the game-code used to compile the .qvm files for
|
|
|
|
the game logic freely available to everyone. Furthermore, note that the "QIIIA
|
|
|
|
Game Source License" prohibits distribution of mods that are intended to
|
|
|
|
operate on a version of Q3 not sanctioned by id software:
|
|
|
|
|
|
|
|
"with this Agreement, ID grants to you the non-exclusive and limited right
|
|
|
|
to distribute copies of the Software ... for operation only with the full
|
|
|
|
version of the software game QUAKE III ARENA"
|
|
|
|
|
|
|
|
This means that if you're creating a standalone game, you cannot use said
|
|
|
|
license on any portion of the product. As the only other license this code has
|
|
|
|
been released under is the GPL, this is the only option.
|
|
|
|
|
|
|
|
This does NOT mean that you cannot market this game commercially. The GPL does
|
|
|
|
not prohibit commercial exploitation and all assets (e.g. textures, sounds,
|
|
|
|
maps) created by yourself are your property and can be sold like every other
|
|
|
|
game you find in stores.

Network protocols
|
|
|
|
There are now two cvars that give you some degree of freedom over the reported
|
|
|
|
protocol versions between clients and servers: "protocol" and "oldprotocol".
|
|
|
|
The reason for this is that some standalone games increased the protocol
|
|
|
|
number even though nothing really changed in their protocol and the ioquake3
|
|
|
|
engine is still fully compatible.
|
|
|
|
|
|
|
|
In order to fix a vulnerability in the network protocol as outlined in
|
|
|
|
|
|
|
|
http://aluigi.altervista.org/papers/q3noclient.txt
|
|
|
|
|
|
|
|
a new network protocol was introduced that defends against such attacks.
|
|
|
|
Unfortunately, this protocol will be incompatible to the original quake3 1.32c
|
|
|
|
which is the latest official release from id.
|
|
|
|
Luckily, ioquake3 has backwards compatibility, on the client as well as on the
|
|
|
|
server. This means ioquake3 players can play on old servers just as ioquake3
|
|
|
|
servers are able to service old clients.
|
|
|
|
|
|
|
|
The cvar "protocol" denotes the protocol version for the new hardened
|
|
|
|
protocol, whereas the "oldprotocol" cvar denotes the protocol version for the
|
|
|
|
legacy protocol.
|
|
|
|
If the value for "oldprotocol" and "protocol" is identical, then the legacy
|
|
|
|
protocol is always used. If oldprotocol is set to 0, then support for the
|
|
|
|
legacy protocol is disabled.
|
|
|
|
|
|
|
|
Mods that use a standalone engine obviously do not require dual protocol
|
|
|
|
support, and it is turned off if the engine is compiled with STANDALONE per
|
|
|
|
default. You can enable it in q_shared.h if desired by defining
|
|
|
|
PROTOCOL_SUPPORT_OLD.

cl_guid Support
|
|
|
|
cl_guid is a cvar which is part of the client's USERINFO string. Its value
|
|
|
|
is a 32 character string made up of [a-f] and [0-9] characters. This
|
|
|
|
value is pseudo-unique for every player. Id's Quake 3 Arena client also
|
|
|
|
sets cl_guid, but only if Punkbuster is enabled on the client.
|
|
|
|
|
|
|
|
If cl_guidServerUniq is non-zero (the default), then this value is also
|
|
|
|
pseudo-unique for each server a client connects to (based on IP:PORT of
|
2007-08-23 17:23:15 +00:00
|
|
|
the server).
|
2007-02-13 16:18:35 +00:00
|
|
|
|
|
|
|
The purpose of cl_guid is to add an identifier for each player on
|
|
|
|
a server. This value can be reset by the client at any time so it's not
|
|
|
|
useful for blocking access. However, it can have at least two uses in
|
|
|
|
your mod's game code:
|
|
|
|
1) improve logging to allow statistical tools to index players by more
|
|
|
|
than just name
|
2007-08-23 17:23:15 +00:00
|
|
|
2) granting some weak admin rights to players without requiring passwords

PNG support
|
|
|
|
ioquake3 supports the use of PNG (Portable Network Graphic) images as
|
2007-08-26 21:27:46 +00:00
|
|
|
textures. It should be noted that the use of such images in a map will
|
2007-08-23 17:23:15 +00:00
|
|
|
result in missing placeholder textures where the map is used with the id
|
|
|
|
Quake 3 client or earlier versions of ioquake3.
|
|
|
|
|
2007-08-26 21:27:46 +00:00
|
|
|
Recent versions of GtkRadiant and q3map2 support PNG images without
|
|
|
|
modification. However GtkRadiant is not aware that PNG textures are supported
|
|
|
|
by ioquake3. To change this behaviour open the file 'q3.game' in the 'games'
|
|
|
|
directory of the GtkRadiant base directory with an editor and change the
|
|
|
|
line:
|
|
|
|
|
|
|
|
texturetypes="tga jpg"
|
|
|
|
|
|
|
|
to
|
|
|
|
|
|
|
|
texturetypes="tga jpg png"
|
|
|
|
|
|
|
|
Restart GtkRadiant and PNG textures are now available.

Building with MinGW for pre Windows XP
|
|
|
|
IPv6 support requires a header named "wspiapi.h" to abstract away from
|
|
|
|
differences in earlier versions of Windows' IPv6 stack. There is no MinGW
|
|
|
|
equivalent of this header and the Microsoft version is obviously not
|
|
|
|
redistributable, so in its absence we're forced to require Windows XP.
|
|
|
|
However if this header is acquired separately and placed in the qcommon/
|
|
|
|
directory, this restriction is lifted.

Please send all patches to bugzilla (https://bugzilla.icculus.org), or join the
|
|
|
|
mailing list (quake3-subscribe@icculus.org) and submit your patch there. The
|
|
|
|
best case scenario is that you submit your patch to bugzilla, and then post the
|
2008-08-09 13:25:41 +00:00
|
|
|
URL to the mailing list.

The focus for ioq3 is to develop a stable base suitable for further development
|
|
|
|
and provide players with the same Quake 3 experience they've had for years. As
|
|
|
|
such ioq3 does not have any significant graphical enhancements and none are
|
|
|
|
planned at this time. However, improved graphics and sound patches will be
|
|
|
|
accepted as long as they are entirely optional, do not require new media and
|
|
|
|
are off by default.

--------------------------------------------- Building Official Installers -----
|
|
|
|
|
|
|
|
We need help getting automated installers on all the platforms that ioquake3
|
|
|
|
supports. We don't neccesarily care about all the installers being identical,
|
|
|
|
but we have some general guidelines:
|
|
|
|
|
|
|
|
* Please include the id patch pk3s in your installer, which are available
|
2007-12-04 06:55:16 +00:00
|
|
|
from http://ioquake3.org/patch-data/ subject to agreement to the id
|
2006-11-09 14:51:24 +00:00
|
|
|
EULA. Your installer shall also ask the user to agree to this EULA (which
|
|
|
|
is in the /web/include directory for your convenience) and subsequently
|
|
|
|
refuse to continue the installation of the patch pk3s and pak0.pk3 if they
|
|
|
|
do not.
|
|
|
|
|
|
|
|
* Please don't require pak0.pk3, since not everyone using the engine
|
|
|
|
plans on playing Quake 3 Arena on it. It's fine to (optionally) assist the
|
|
|
|
user in copying the file or tell them how.
|
|
|
|
|
|
|
|
* It is fine to just install the binaries without requiring id EULA agreement,
|
|
|
|
providing pak0.pk3 and the patch pk3s are not refered to or included in the
|
|
|
|
installer.
|
|
|
|
|
2008-08-09 13:25:41 +00:00
|
|
|
* Please include at least an SDL so/dylib/dll on every platform.
|
2006-11-09 14:51:24 +00:00
|
|
|
|
|
|
|
* Please include an OpenAL so/dylib/dll, since every platform should be using
|
|
|
|
it by now.
|
|
|
|
|
2008-08-09 13:25:41 +00:00
|
|
|
* Please contact the mailing list when you've made your installer.
|
2006-11-09 14:51:24 +00:00
|
|
|
|
|
|
|
* Please be prepared to alter your installer on the whim of the maintainers.
|
|
|
|
|
|
|
|
* Your installer will be mirrored to an "official" directory, thus making it
|
|
|
|
a done deal.
