Rotate a graphic round the middle

[Miikku]

Hi!
(sorry for my bad english, it's because I'm german:*))

I have a problem, because I don't know, how to rotate a graphic ("Sprite") round his middle. (Normaly (with "pic.angle = 180") it turns round the point upper-left. (I want do make a Ball witch rolls)

I'm happy if anyone can help me

Use this:

sprite.ox = sprite.width / 2
sprite.oy = sprite.height / 2
sprite.angle = 180
