Community Base addons A3

CBA Team

What does the name Community Base Addons mean? It is a system that:
  • Offers a range of features for addon-makers and mission designers.
  • Aims to have community wide acceptance and to be used as much as possible by community addons to maintain compatibility.
  • The community is very much encouraged to request or submit functionality
      - The most obvious example would be to submit functions to be included in the CBA function library.

- Extended Eventhandlers (XEH)
- Function and Macro Libraries
- Key Management
- Custom Events System
- Author and Credits system (Displayed during Main Menu and Pause Menu)
- Nil Check
- Help System
- Versioning System
- UI System

Extract into the ArmA 3 Directory, by default this is located in:
32-Bit - C:/Program Files/Steam/Steamapps/Common/ArmA 3/
64-Bit - C:/Program Files (x86)/Steam/Steamapps/Common/ArmA 3/
After extraction it should look like this:
Steam/Steamapps/Common/ArmA 3/@your_mod_folder_name

You can also use the "Arma 3" folder in your "My Documents" folder. Your folder setup could than look like for example this:

Place the "userconfig" folder into your game install folder, usually:
"C:\Program Files (x86)\Steam\steamapps\common\Arma 3".

You'll also need to add a Launch Parameter to Steam, in order to do so right-click on ArmA 3 and click Properties and then Set Launch Options. In the window that opens enter in -mod=@your_mod_folder_name
For using multiple mods you would then do so like this:

You can also use -nosplash to get rid of the splash art and intro videos.

And of course you can also enable and disable community made addons and mods through the in-game Options Expansions menu if you do not want to mess with startup parameters!

When the above information still does not provide you with enough to learn how to install custom addons and mods you can always ask in our Guide On Installing Mods.

Any addon which calls CBA-defined functions need not be licensed under the GPLv2 or released under a free software license. Only if you are directly including CBA code in your addon's binarized PBO or redistributing a modified version of CBA itself would your work be considered derivative and therefore be legally required to be released under the terms of the GPL. (And there's no reason to ever do either of these.)
