Box2D rotating bat test problem

[Bruto]

hey,

why this getting buggy? I suppose it's because I should use rotating joints?

The problem is that the shape of the rotating body is misplaced. Shapes are added relative to the body's origin, which is the same as the objects hot spot in this case, so the shape is added 180 degrees off.

Also, for this kind of simulation you should make the body dynamic and rotate it by activating the revolute joint's motor. Directly setting the angle/position of a body like this will result in tunneling.

If you want a clearer overview what is happening, add an Overlay covering the screen and start Box2D's debug-draw in it.

hmmm I see. I'll keep studying this extension and see what I can do with it. Many thanks!
