I found this animation http://youtube.com/watch?v=wt6gsIcNBOA (have a look at 1:46). I can not find anything how this animation was accomplished. Basically it should look like the scene is cut into 3 different parts.
Any idea how to make a similar animation ?
its a "simple" CCTransitionSplitRows animation
CCTransitionSplitRows *transition = [CCTransitionSplitRows transitionWithDuration:1 scene:scene];
[[CCDirector sharedDirector] replaceScene:transition];
there are more of such fancy transition in cocos2d see http://www.pawapps.com/2011/07/30/tutorial-transitions-in-cocos2d/ for example
