Creating a lever

Create a shape when you start a touch event and remove it when the touch ends. You can update the finger object's position/velocity like the mouseBody in the official Chipmunk demo app.

I forgot to write it! that I tried this too...
But what happens is that if I make a quick movement the object crosses the lever without moving it...

maybe I can try again this way, and change something...

Well in the chipmunk demo code I smooth out the motion of mouse to help avoid this. You can also explicitly clamp the distance it can move each frame too.

ok!
at least now I know there's not an obvious way to do that!
