CBA: Community Based Addons for Arma 3
Current version: 3.9.0
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.
Full documentation is available at GitHub[]

Licensed Under GPLv2
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.)

Hello there. Id like to report an issue. When i run cba i cant get into jets. It sais to me "you need to be a pilot to fly" and kicks me out. But the funny think i spawn as a fighter pilot. Once i disabled it the problem was gone. I did series of test so im 100% sure. Thank you for your time

Some mods and campaigns(eg. range of death) that are intergating old version CBA components are now conflict with ACE. I think that's the reason for "ACE requires 3.9 or higher".

@reptilienski how does one do this rebuilding you speak of

Guys, I fully tested everything and fix the "ACE requires 3.9 or higher though" issue, it seems it was not CBA's issue but some other stuff. What I did was, I used have some missions with old CBA modulars and ACE modulars in it, and after the newest ACE update seem some of the ACE modulars use in the missions are out dated, so I fully rebuild all the missions with the new ACE and CBA modulars and now everything works fine, no error. I think whatever missions you are current using might be outdated and you need to update it youself or wait for an update from the original mission maker.
