I made a small example of using the json output of the R.U.B.E. box2d editor (http://www.iforce2d.net/b2deditor/
) to create and display a box2d world. It uses the JSON4Lua library (JSON4Lua library: http://json.luaforge.net/
) to read the json output and convert it to a lua table. Some ugly lua code that I wrote (with help from atilim -- thanks!) then converts the lua table to a box2d world.
The code & simple gideros project can be found at: https://bitbucket.org/ndoss/gideros_playground
One question I have about the box2d implementation in gideros -- is there a way to interact with the box2d elements if using b2.DebugDraw?
