Patching advice needed

this is my first attempt to patch (box2d) with sub-patches and I d like to know if it can be done any better. I see already some scattering movement when I create new bodies.
There are 120 fixed (density == 0) boxes and 6 different trigger to create 6 different floating boxes.


Uh looks like I had not load the file… here it goes …
