QUAKE3 FILESYSTEM
|
|
|
|
All of Quake's data access is through a hierarchical file system, but the contents of
|
|
the file system can be transparently merged from several sources.
|
|
|
|
A "qpath" is a reference to game file data. MAX_ZPATH is 256 characters, which must include
|
|
a terminating zero. "..", "\\", and ":" are explicitly illegal in qpaths to prevent any
|
|
references outside the quake directory system.
|
|
|
|
The "base path" is the path to the directory holding all the game directories and usually
|
|
the executable. It defaults to ".", but can be overridden with a "+set fs_basepath c:\quake3"
|
|
command line to allow code debugging in a different directory. Basepath cannot
|
|
be modified at all after startup. Any files that are created (demos, screenshots,
|
|
etc) will be created relative to the base path, so base path should usually be writable.
|
|
|
|
The "home path" is the path used for all write access. On win32 systems we have "base path"
|
|
== "home path", but on *nix systems the base installation is usually readonly, and
|
|
"home path" points to ~/.q3a or similar
|
|
|
|
The user can also install custom mods and content in "home path", so it should be searched
|
|
along with "home path" and "cd path" for game content.
|
|
|
|
|
|
The "base game" is the directory under the paths where data comes from by default, and
|
|
can be either "baseq3" or "demoq3".
|
|
|
|
The "current game" may be the same as the base game, or it may be the name of another
|
|
directory under the paths that should be searched for files before looking in the base game.
|
|
This is the basis for addons.
|
|
|
|
Clients automatically set the game directory after receiving a gamestate from a server,
|
|
so only servers need to worry about +set fs_game.
|
|
|
|
No other directories outside of the base game and current game will ever be referenced by
|
|
filesystem functions.
|
|
|
|
To save disk space and speed loading, directory trees can be collapsed into zip files.
|
|
The files use a ".pk3" extension to prevent users from unzipping them accidentally, but
|
|
otherwise the are simply normal uncompressed zip files. A game directory can have multiple
|
|
zip files of the form "pak0.pk3", "pak1.pk3", etc. Zip files are searched in decending order
|
|
from the highest number to the lowest, and will always take precedence over the filesystem.
|
|
This allows a pk3 distributed as a patch to override all existing data.
|
|
|
|
Because we will have updated executables freely available online, there is no point to
|
|
trying to restrict demo / oem versions of the game with code changes. Demo / oem versions
|
|
should be exactly the same executables as release versions, but with different data that
|
|
automatically restricts where game media can come from to prevent add-ons from working.
|
|
|
|
File search order: when FS_FOpenFileRead gets called it will go through the fs_searchpaths
|
|
structure and stop on the first successful hit. fs_searchpaths is built with successive
|
|
calls to FS_AddGameDirectory
|
|
|
|
Additionally, we search in several subdirectories:
|
|
current game is the current mode
|
|
base game is a variable to allow mods based on other mods
|
|
(such as baseq3 + missionpack content combination in a mod for instance)
|
|
BASEGAME is the hardcoded base game ("baseq3")
|
|
|
|
e.g. the qpath "sound/newstuff/test.wav" would be searched for in the following places:
|
|
|
|
home path + current game's zip files
|
|
home path + current game's directory
|
|
base path + current game's zip files
|
|
base path + current game's directory
|
|
cd path + current game's zip files
|
|
cd path + current game's directory
|
|
|
|
home path + base game's zip file
|
|
home path + base game's directory
|
|
base path + base game's zip file
|
|
base path + base game's directory
|
|
cd path + base game's zip file
|
|
cd path + base game's directory
|
|
|
|
home path + BASEGAME's zip file
|
|
home path + BASEGAME's directory
|
|
base path + BASEGAME's zip file
|
|
base path + BASEGAME's directory
|
|
cd path + BASEGAME's zip file
|
|
cd path + BASEGAME's directory
|
|
|
|
server download, to be written to home path + current game's directory
|
|
|
|
|
|
The filesystem can be safely shutdown and reinitialized with different
|
|
basedir / cddir / game combinations, but all other subsystems that rely on it
|
|
(sound, video) must also be forced to restart.
|
|
|
|
Because the same files are loaded by both the clip model (CM_) and renderer (TR_)
|
|
subsystems, a simple single-file caching scheme is used. The CM_ subsystems will
|
|
load the file with a request to cache. Only one file will be kept cached at a time,
|
|
so any models that are going to be referenced by both subsystems should alternate
|
|
between the CM_ load function and the ref load function.
|
|
|
|
TODO: A qpath that starts with a leading slash will always refer to the base game, even if another
|
|
game is currently active. This allows character models, skins, and sounds to be downloaded
|
|
to a common directory no matter which game is active.
|
|
|
|
How to prevent downloading zip files?
|
|
Pass pk3 file names in systeminfo, and download before FS_Restart()?
|
|
|
|
Aborting a download disconnects the client from the server.
|
|
|
|
How to mark files as downloadable? Commercial add-ons won't be downloadable.
|
|
|
|
Non-commercial downloads will want to download the entire zip file.
|
|
the game would have to be reset to actually read the zip in
|
|
|
|
Auto-update information
|
|
|
|
Path separators
|
|
|
|
Casing
|
|
|
|
separate server gamedir and client gamedir, so if the user starts
|
|
a local game after having connected to a network game, it won't stick
|
|
with the network game.
|
|
|
|
allow menu options for game selection?
|
|
|
|
Read / write config to floppy option.
|
|
|
|
Different version coexistance?
|
|
|
|
When building a pak file, make sure a q3config.cfg isn't present in it,
|
|
or configs will never get loaded from disk!
|
|
|
|
todo:
|
|
|
|
downloading (outside fs?)
|
|
game directory passing and restarting
|
