Box2d :roll soft body ball

2019-07-27 10:46发布

I made a soft body ball int box2d that looks like that:

enter image description here

Every point of the circle is a box2d body and every line is a distance joint. How can i roll it? I don't want to change the world gravity and just let it roll , I want it to start spinning from the center (not every circle point independent).

I just need the geeneral idea ,not code.

The general idea is to apply the right force to each body. If you want rotation - these forces are normals to the vectors from the center of the ball to the center of the body.
