Documentation here: http://rabbitb.bitbucket.org/Paradox3D/
I’ve been playing around with and learning Paradox 3D off and on, and I’ve found that the available documentation online hasn’t really been well suited to help me learn more about, or explore the API; especially since there’s no documentation search available.
Hopefully this is alright, but my solution was to whip together a new set of documentation using Doxygen to generate it, and post it online using my Bitbucket account to host. The docs are available here: http://rabbitb.bitbucket.org/Paradox3D/
To generate the documentation, there was one file that needed to be excluded (contained no part of the API, so fortunate there), as it exceeded the 256k character limit per line and/or interpretation unit that Doxygen enforces. The documentation search is also Javascript dependent (not server-side), so you’ll need JS enabled in your browser to use it.
