Hi Homatenbeo, I'll redirect you to the relative sample: https://github.com/ymobe/rapanui/blob/rapanuidev/rapanui-samples/physics/rn-physics-filters.lua

Hi MattiaFortunati I see your example, but it's still not exactly what I was wondering .

I have C, groupindex = -1 A and B do not put groupindex. problem : C still collides with A and B.

Any help much appreciated . i'm sorry, i'm poor english. Thanks. Homatenbeo

You should check box2d documentation. Also, I found this: http://stackoverflow.com/questions/936935/box2d-collision-groups
