Absolute scaling of circle body

Is there any possibility to scale circle with absolute value? Body.scale method is relative to current size. I have to scale it down, and then scale it back to initial size. I could do the math to reverse the scaling, but in this case the value depends on object position.

One thing to know is that unlike in a graphics engine, bodies keep their own geometry absolute in world-space for performance reasons, as well as to simplify the overall implementation.

So if you need some sense of ‘absolute scale’ you should keep track of all scaling applied relative to the initial scale. In other words every time you scale the body using Body.scale(body, scale, scale), also keep track of that by scaling a stored scale factor at the same time e.g. body._currentScale *= scale.

Then to revert to the original scale for example, you can do this:

Body.scale(body, 1 / body._currentScale, 1 / body._currentScale);

I also needed to scale the body, and with easing, which was to complex math for me. Solved it for any shape (single part only) by storing two copies of the vertices-array. One with the original and one with manipulated values. In the animation, gasp I’m my case. I multiply the original vertices with a scale-factor and save to the manipulated array (by index to avoid creating new arrays each frame). Then set the vertices on the body. Then finally applying rotation on the vertices to the same as the current body.angle, because body rotations are changing it’s vertices.
