[libgdx][Box2D] How to convert Box2D coordinates to World coordinates (again)

Hello :).

I know there are already several topics about this issue but I still do not get it ;).

I’m trying to translate my Box2D coordinates to World coordinates in order to draw my sprites (at the moment only shapes).

Therefore I multiply the size of the Box2D coordinates with the scaling factor like this:


...
float scaleFactor = 5;
_shapeRenderer.circle(_bp.getBody().getWorldCenter().x, _bp.getBody().getWorldCenter().y, _bp.getSize().width * scaleFactor);
...

This is the result on the screen:

When I scale the size of my sprites/shapes I will always have intersecting sprites/shapes.

Perhaps I’m missing the forest for the trees but I don’t know how to get it right.

Any help would be really appreciated ;D
