@amihanya - attach is in the docs under DOCS - ZIM JavaScript Canvas Framework - Documentation and then down under the second set of methods.
We should be able to do rotation to... have you done scale before? I think I remember you asking. What was the solution? We can search back on Slack now... for a few more days.
In my project i remove the physics and add it every change 
so its not help to that request
I looked for scale in Box2D and it did not have it... it did have rotation, x and y. Ah... just looked again and a circle can have its fixture.GetShape.m_radius changed.

We will try and experiment with this a little later...
