Re: [android-developers] Re: New OpenGL ES 2.0 Game Engine Option

Thanks bob!  That game was from before BatteryTech and was the reason we built a proper game engine.

By the way, I tried your Deadly Chambers game.  It is impressive.  I like how the guy's name is Chambers.  Very funny.

Yes, texture mapping is fairly standard and is very well supported.

BAI means "Binary Asset Import" and is a compact memory-safe format of the internal structure of the open asset importer library.  We did create it ourselves but it's simple, easy to maintain and extend and fully compatible with version 2 of that library, which is why you can easily add more formats to the engine.

Also,


Does it support texture-mapped models?


And, is the BAI format your own invention?

Out of the box it supports OBJ for static geometry and Collada (DAE) for static and animated models.  We have a utility that will convert either of those to a binary format called BAI to go to production because it's smaller and loads faster.  The engine uses a library called Open Asset Import which supports 30+ formats, so if you want more formats supported, all you have to do is add in the format support files to either the engine or the BAI conversion utility.  I think the only format that isn't supported by Open Asset Importer is FBX, but autodesk has good FBX to DAE conversion utilities that work, so there is that option.

Looks interesting.  What 3d model formats does it support?

Hi All,

I'm a long time contributor of this group (over 400 posts I think), developer of Deadly Chambers, Antigen and several other Android games and just wanted to, in good will, let you know about the game engine that we've been developing for the past 2 years.  It's called BatteryTech Engine and is available at http://www.batterytechsdk.com .  It's full OpenGL ES 2.0 and was designed around Android so that it would work really well across over 1000 devices, maybe more.  It's free to develop but does require a license to deploy.  The license gets you full engine source code which is something you don't see often from comparable engines.  We completely integrated Box2D and everything is bound to Lua to make it really easy to script out game logic.  You can also deploy on other platforms, but it works great specifically for Android too.

Please let me know what you think, either here, privately or otherwise.  Would love feedback and am always happy to support.

Thanks everyone!!
