Irrlicht on Android

[guite]

Hello everyone,

I am currently trying to find a documentation on how to run irrlicht on Android. I’ve found several threads on the web talking about a port of irrlicht on Android but sadly, everything I tried led me to a dead end… Is there an official documentation for running irrlicht in an android activity ? I couldn’t find any topic about Android in Irrlicht documentation nor in the wiki (did I try hard enough ? ).

The best I could do was downloading the ogl-es branch of irrlicht, but when I tried compiling the example 17.Helloworld_mobile in visual, the project failed because another required project (..\..\source\Irrlicht\Irrlicht_mobile6.vcproj) was not found.

I was also wondering if I could use something like SWIG for wrapping irrlicht in java (objective-C) and using it in an Android (or iOS) app but I wonder how to create a irrlicht::device from an android view (or iOS view) ; is it possible ? Is there a documentation on how to do this ?

If anyone can give information on any of those questions, it is more than welcome

PS: Even if I tried compiling irrlicht/ogl-es on windows/visual, I’d rather have a documentation that explains how to do so on linux (I use Ubuntu a lot more).

Sorry, it seems something got messed up on our svn server recently. I just noticed there is suddenly a new ogl-es branch in the main-folder which is outdated and wrong and doesn't even belong there. I suspect you used that one... sorry.... have to contact that developer and ask what this is about.

The correct ogl-es branch to use is the one in branches/ogl-es - and this version also includes an example (27.HelloWorld_Android) which comes with documentation for building the Android version.

Oh OK, I was indeed trying to compile the branch ogl-es in the main svn folder >_<

Thank you very much for warning me, I’ll try the branch “branches/ogl-es” asap.

Regards,

EDIT:

It worked like a charm ! \o/
I had one compilation error due to the fact that the return type of the CAndroidAssetReader::read method hasn’t got the same type than its parent function IReadFile::read. Just in case someone would be interested, I would suggest this tiny diff:

The last change being just a tiny tiny consistency problem.
