Physics for arc graphics object!

[flowabuse]

How can I add physics to a object like this :http://jsfiddle.net/f6tf8ue9/17/  ? I am trying to make a breakout game and i want to use an arc that moves and scales in a circular manner ( exactly like the progress bar in the link)  , that would be my paddle that would not allow a ball to reach the center. Can this even be done?

Physics bodies can only be applied to sprites. The arc in the fiddle is a bitmapdata. However, bitmapdata can be used as a sprite's texture. This is done by specifying the bitmapdata's key when you create the sprite, same as any other kind of sprite texture. So you should try creating the paddle as a sprite with the bitmapdata arc as its texture.

I decided to test out what I said. Turned out to be easy in this case, because I looked at the fiddle you provided again and noticed that PieProgress extends the Sprite class, so it turned out they'd already beaten me to the whole "apply bitmapdata to sprite" idea. So I tried enabling physics and applying gravity to the circle, and it works fine. The radius continues to update properly when you adjust it, but the other properties don't work anymore. I'm sure it's fixable. Check it out here: http://jsfiddle.net/f6tf8ue9/18/ (check the "create" function for the code I added).

The problem is I want the physics body shape to be the same as the 'pie' object, and to modify it using the 'progress'. So a rectangle or a circle body won't work for me.
