Is there an easy way to have the screen shake when I have an explosion in the game?

By shake I don’t mean for the actual phone to vibrate, but rather the image on the screen to sort of instantaneously “jump”. For example, what I’m specifically talking about is shown at the 25 second mark in this video.

If your screen is all in one display group, perhaps a series of small transitions to random x/y offsets?

it’s very easy to implement when working with storyboard, because you have access to the scene view group:

scene.view.x
scene.view.y
