I'm trying to figure out how to increase the diameter of a circle shape during gameplay.
I've checked the examples for both Box2D or Chipmunk extensions, and I understand how you create a new circle shape with a specified size parameter. But I can't figure out if there a way to change that size later after the shape was created.
I want to make something like a ball that shrinks and grows.

This is kind'a urgent since I'm experimenting for a 48 hours game jam.

im assuming its an active object, if yes then you can play around with the scale parameters at runtime.

Yes, the hot spot is the centre of the expansion.

He's referring to 'shapes' as used with Box2D, not active object scaling.
