2 并行動作和序列動作
CCSequence 中持續(xù)時間為所有動作累計的總合，CCSequence 中不可以
有CCRepeatForever 動作。
???CCSpwan中持續(xù)時間為并行動作持續(xù)時間最長的決定。
3 假動作
???CCCallFunc系列動作包括CCallFunc()、CCCallFuncN()、CCCallFuncND,以及CCCallFuncO四個動作，CCCallFunc系列動作的后綴”N”表示Node參數，指的是執(zhí)行動作的對象，”D”表示Data參數，指的是用戶自定義的數據，”O(jiān)”表示對象，指的是一個用戶自定義的CCObject參數。在不同的情況下，我們可以根據不同的需求來選擇不同的CCCallFunc動作。
