If two shapes are using a same body, then how will we set the position of the body

body->p = shape1.position;
or

body->p = shape2.position;

How should I handle it

Shapes are always positioned relative to bodies. When the body moves, so will the shapes.

Yes, shapes will be updated according to the position of body. But, Don't we have to give initial position of body.

The position of the body is the position of it's center of gravity. The shapes move and rotate around that.

So when you set the position of the body initially, you are setting it's center of gravity. The shapes attached are always relative to that.

I got it, Thanks for your help
