What is OAX? Edit

These "beta" releases are previews of what will be OpenArena in the next official releases and are distributed as mods for easy testing.

In these betas you can find, for example, new game options, changes in the user interface, and in the rules of the gamemodes.

Up to beta version 21 (June 2008), "OAX" was known as "Elimination" (because of the "test mod" was first created when testing the Elimination gametype), then it was renamed to "OpenArena eXpanded".

R and BEdit

Please notice that you may find two different OAX numberings: "R" and "B" versions. "R" stands for "revision" (a.k.a. "rev"): each time a developer updates the source code/files on the "svn repository" (in short, makes a change), the "R" version number goes ahead; this allows to track each change, but you need "the hard way" below to test these latest changes. "B" stands for "beta": once on a while, a developer creates a "beta" package (starting from a specific "R" version) that everyone can simply download and test in "the easy way", like a mod; these downloads may miss the very latest changes, done after their creation. An OAX B version number is lower than the corresponding OAX R number, since a new beta package contains the changes introduced with more revisions; as an example, Beta 47 is based on OAX r238.

Where to find it? Edit

You can find news about OpenArena Expanded here. It contains a download link for the source code and the "playable mod" version, description of the changes for each beta version, plus that thread is the place you can give feedback for them.

Furthermore, when a big change is implemented, so the engine must be touched, the thread about the latest test binaries is the place to go in order to download the latest binaries.

Testing Edit

The easy wayEdit

To easily test an OAX beta version, use it like any mod (see Manual/Using mods):

1. Go to the forums, to the thread about OAX.
2. Download an OAX Beta version "mod"
3. Unzip it inside your OpenArena installation folder (or user settings folder), so you should obtain a subfolder called "oaxBXX" (where XX is the beta version number, for example "oaxB45" for Beta 45, "oaxB46" for Beta 46... you can have more OAX beta versions "mods" installed). Note: this folder goes at the same level of the "baseoa" folder, not inside it... and do not mix the files from the mod with those in baseoa.
4. Start OpenArena, then select "Mods", and there choose "oaxBXX"
5. Use the game and try it. Please refer to the "readme.txt" file or to the thread on the forum to know what's new in each beta version.

The hard wayEdit

To test the very latest changes (the ones that can be viewed in the changelog) you can checkout from svn and compile yourself. This is also relevant if you want to make your own changes or tests.

1. Install a subversion client. In Ubuntu Linux this is done with "sudo aptitude install subversion". In Microsoft Windows must use TortoiseSVN software.
2. Checkout with "svn checkout http://oax.googlecode.com/svn/trunk/ oax-read-only". In TortoiseSVN http://oax.googlecode.com/svn/trunk/ must be entered as address like this:
3. Compile. In Windows run windows_compile_game.bat, windows_compile_cgame.bat and windows_compile_q3_ui.bat in "windows_scripts". This will create a folder called "windows" with a subfolder called "baseoa". In "baseoa" is a folder called vm. Compress vm to a zip file. Call it oaxdev.pk3 copy it into a oax-folder next to baseoa where you installed OpenArena. Linux users can use the "supermake"-script in "linux_scripts" to compile, pack and launch the game in one command.
4. Start the game select oax as a mod. Unless you use the "supermake"-script as that will also launch the game with the mod active.

Coding tutorials and resources Edit

Submitting changes Edit

If you have developed a change, as long as it doesn't violate NOTTODO, propose it in the OAX thread.
