Let’s see what I changed from the original script

First, I changed GetBodyAtMouse function – lines 104-126 – so it only returns static objects at line 116.

Then, I modified createMouse function – lines 90-97 – in order to create a joint between the center of the ball and the mouse position in the selected static object, and obviously the destroyMouse one to remove the joint when I release the mouse.

There isn’t much more to see that you can’t see in the posts I mentioned before.

Here it is the result:

Click on a static object (green) to create a joint on the fly

No need to include the source code, just replace the script at Box2D joints: Distance Joint with this one.
