I can't get shake to work

I must be missing something incredibly obvious, but I can't for the life of me get shake to work.

The object set to shake has no events to it, it's just a sprite acting as a background, I set the scroll to behaviour to on on it.

Shake is supposed to shake the screen.

So either your layout's size has to be bigger than your project's window's size, or the layout "Unbounded scrolling" property must be true.

Posting your project might make it easier to investigate what may be going on.

Indicate precisely what you are looking to achieve and what you experience your actual project doing.
