love.physics, change size after creation?

[Jeeper]

Hey!
I have been playing around with the love.physics quite a bit but i have not been able to figure one thing out. Is it possible to change the size (width, height) of a shape after its been created (with for example love.physics.newRectangleShape)?

Thanks a lot in advance!

You can change the Radius of a CircleShape but I don't think you can modify the dimensions of the Polygon.

I think you have to destroy the fixture and create a new fixture with your enlarged shape.
