Quite a few people have used libgdx to create WebGL/HTML5 versions of their games, both 2D and 3D. Stefan Wagner, alias Bompo created this for the last ludum dare (click image to play):
It’s a 3D arcade game. You control a ship in a backyard pond and fire at other ships. Really neat for 48h!
Dimitry Fink created Stargazer for Android and Facebook:
This one’s a puzzle game, where you rotate a star configuration in 3D to become a 2D object. It’s an insanely cool idea and the mechanics got me hooked this morning. What’s interesting about this one is that it integrates with the Facebook APIs via JSNI, a way to communicate with Javascript from Java in GWT. Hopefully Dimitri will enlighten us on what was involved getting this to work.
Robert Engelbert ported his Frogger tutorial game not only to Android put to WebGL as well:
You should totally check out his blog which is filled with all kinds of game programming tutorials. He has a series on implementing frogger with various frameworks, including libgdx. Well worth a read.
Those are just 3 recent games i discoverd, there are a lot more WebGL/libgdx games out there already, some on the Google Chrome store. Let’s hope WebGL compatibility gets even better in the coming months!
