screen shake

I kow if i add the Scroll To behaviour there's a shake scree option, so if i want to shake my background how do i do this..?

Shake just the background? I'm not sure if that's possible using the ScrollTo behavior. You might have to do it manually, which would involve making it move in random directions for very very short amounts of time. I don't have time now but in about an hour I could try to whip up an example for you.

Thanks i have done it manually with timing and making it move left, right etc alot of events though..
