|
|
|
|
The intent of this project is to provide a baseline Quake 3 which may be used
|
|
for further development. Some of the major features currently implemented are:
|
|
|
|
* SDL backend
|
|
* OpenAL sound API support (multiple speaker support and better sound
|
|
quality)
|
|
* Full x86_64 support on Linux
|
|
* MinGW compilation support on Windows and cross compilation support on Linux
|
|
* AVI video capture of demos
|
|
* Much improved console autocompletion
|
|
* Persistent console history
|
|
* Colorized terminal output
|
|
* Optional Ogg Vorbis support
|
|
* Much improved QVM tools
|
|
* Support for various esoteric operating systems (see
|
|
http://ioquake3.org/?page=status)
|
|
* cl_guid support
|
|
* HTTP/FTP download redirection (using cURL)
|
|
* Multiuser support on Windows systems (user specific game data
|
|
is stored in "%APPDATA%\Quake3")
|
|
* PNG support
|
|
* Many, many bug fixes
|
|
|
|
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'.
|
|
|
|
For Windows, using MinGW
|
|
1. Download and install MinGW and MSys from http://www.mingw.org/.
|
|
2. Open an MSys terminal, and follow the instructions for compiling on *nix.
|
|
|
|
For Mac OS X, building a Universal Binary
|
|
1. Install the MacOSX10.2.8.sdk and MacOSX10.4u.sdk which are included in
|
|
XCode 2.2 and newer.
|
|
2. Change to the directory containing this README file.
|
|
3. Run './make-macosx-ub.sh'
|
|
4. Copy the resulting ioquake3.app in /build/release-darwin-ub to your
|
|
/Applications/ioquake3 folder.
|
|
|
|
Installation, for *nix
|
|
1. Set the COPYDIR variable in the shell to be where you installed Quake 3
|
|
to. By default it will be /usr/local/games/quake3 if you haven't set it.
|
|
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
|
|
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.
|
|
|
|
The following variables may be set, either on the command line or in
|
|
Makefile.local:
|

------------------------------------------------------------ Miscellaneous -----
|
|
|
|
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.
|
|
|
|
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
|
|
compiler. See http://www.quakesrc.org/forums/viewtopic.php?t=5665 (if it
|
|
still exists when you read this) for more details.
|
|
|
|
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
|
|
the server).
|
|
|
|
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
|
|
2) granting some weak admin rights to players without requiring passwords
|
|
|
|
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
|
|
2 - do not use HTTP/FTP downloads
|
|
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.
|
|
|
|
SDL's "Dead Key" behaviour makes the hard-coded toggleConsole binds ~ and `
|
|
annoying to use on many non-US keyboards. In response, an additional
|
|
toggleConsole bind has been added on the key combination Shift-Esc.
|
|
|
|
PNG support
|
|
ioquake3 supports the use of PNG (Portable Network Graphic) images as
|
|
textures. It should be noted that the use of such images in a map will
|
|
result in missing placeholder textures where the map is used with the id
|
|
Quake 3 client or earlier versions of ioquake3.
|
|
|
|
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.

------------------------------------------------------------- Contributing -----
|
|
|
|
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
|
|
URL to the mailing list. If you're too lazy for either method, then it would be
|
|
better if you emailed your patches to zakk@icculus.org directly than not at
|
|
all.
|
|
|
|
The focus for ioquake3 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
|
|
from http://ioquake3.org/?page=getdata subject to agreement to the id
|
|
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.
|
|
|
|
* Please include at least an SDL so/dylib on every platform.
|
|
|
|
* Please include an OpenAL so/dylib/dll, since every platform should be using
|
|
it by now.
|
|
|
|
* We'll bump the version to 1.34 as soon as we get enough people who can
|
|
demonstrate a competent build for Windows and Mac.
|
|
|
|
* Please contact the mailing list and/or zakk@timedoctor.org after you've
|
|
made your installer.
|
|
|
|
* 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.
