Is there a way to do it? I can get only polygon_shape's vertices, but i want circle, box, etc too.
How to do it?
There's no such thing as a box in in Box2D (ironically). The SetAsBox
method is a convenience function that creates a 4-ary polygon.
A circle does not have vertices, so you cannot get a list of them. A circle is defined by its radius and its position, and those are both accessible.
Edge and loop shapes use the same vertex storage as a polygon.
