recently I sent the old Box2D-Wrapper to trash and replaced it with the fully featured Box2D-Wrapper from the libGDX-project created by Mario Zechner. The great thing about this is that now also Joints are supported. See the following video of some strong revolute joints kicking some objects around
I finally found the time to upload the following video, that is showing the support for TiledMaps, a grid of small tiles making something bigger than the sum of its parts.
The format I chose (better to say ‘I was made aware of’ ) is the TMX format. TMX is a XML based format, that is mainly human readable but still has very small file-sizes. The biggest plus of the TMX format is that it has a fully featured and easy to use cross-platform Map-Editor called “Tiled”, which can be obtained for free here: http://www.mapeditor.org/.
