Ok i'm having difficulties with Phys2D Body class. When rotating my graphical object I can't get any smooth accuracy.

Currently i'm using
1  
2  
3  
4  
5  
      playerAngle = playerBody.getAngularVelocity();
      if(lastPlayerAngle != playerAngle){
         player.rotateZ(lastPlayerAngle - playerAngle);
        lastPlayerAngle = playerAngle;
      }

This sorta works, but it has large noticible jumps in angle over a time period of seconds.

I tried using Body.getRotation(), but I found that getRotation() value keeps on ever increasing well past 500. This causes my grapical object to rotate extrmely fast. Which is innapropriate.

Is there some way to either get the absolute value of the rotated angle radian or a more precise change as of last getFoo() method call? or just get the rotation of the object smoother.
