How to distort / warp an image?

Is there anyway to distort a pre-define part of an image? Something like HEX DEFENSE background distortion effect.

I would like to have a background, which when an event occurs (such as 2 object collide and exploded or just a simple “touch” event) on any spot, this background will have a warped bouncy effect in a circular pre-defined radius area.

Tried to search this in the forum and also using the search tool but can’t find any.

The nearest I came across is the RAY CASTING ENGINE, where the images can be manipulated to show perspective effects. But that’s just too complicated for my application. [import]uid: 59657 topic_id: 35204 reply_id: 335204[/import]

I’ve been wanting stuff like this for so long, but right now there’s nothing. [import]uid: 51654 topic_id: 35204 reply_id: 139954[/import]
