運作結果：

并行動作和序列動作
ccsequence
中持續時間為所有動作累計的總合，ccsequence
中不可以
有ccrepeatforever
動作。
ccspwan中持續時間為并行動作持續時間最長的決定。

假動作
cccallfunc系列動作包括ccallfunc()、cccallfuncn()、cccallfuncnd,以及cccallfunco四個動作，cccallfunc系列動作的字尾”n”表示node參數，指的是執行動作的對象，”d”表示data參數，指的是使用者自定義的資料，”o”表示對象，指的是一個使用者自定義的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。
