The document shows how to create a sequence of actions in Cocos2D using CCCallFunc, CCCallFuncND, CCSendMessages, and CCSequence. The sequence runs an animationStart method after 1 second, then changes the opacity and scale of a sprite. First CCCallFunc and CCCallFuncND are used, then equivalent actions are shown using CCSendMessages to call methods on targets.
