You can now download Castle Game Engine source code from GitHub, from

Other games/tools using Castle Game Engine have also their separate repository, see

and other repositories listed on .

Clone us, fork us, submit pull requests, and have fun:)

Longer explanation:

- These repositories mirror (are synchronized on an hourly basis) appropriate SVN repositories on SourceForge. The synchronization scripts run on my private server ( ) using sync2git (see my fork of it on ).

- Castle Game Engine SVN repository is split into multiple GIT repositories, because having a large GIT repository is not comfortable (GIT "sparse checkouts" are not as comfortable as checking our a subdirectory in SVN). Using "GitHub organization" for this was natural, to group multiple CGE GIT repositories as one project.

- For now, we treat all these GIT repositories as read-only, and commit through SVN. But this will change as soon as we see people contributing through GitHub (pull requests and such)!

  So fork and submit pull requests as you like --- I'm anxious to see some activity on GitHub related to our engine:)

- One reason for doing this was to not depend so much on SourceForge (seeing it's recent downtime of ~10 days for SVN).

  Another reason was to just encourage more contributors. Many developers (including me:) are accustomed to GIT (and GitHub) workflow and like the ability to fork / submit pull requests. I was working on the SourceForge<->GIT mirroring even before SF downtime:)

So, let's see how this works:) Enjoy!
