Cocos 2dx中的CCSequesnce [英] CCSequesnce in Cocos 2dx

问题描述

为什么在CCSequence操作中传递了Null?

Why Null is passed in CCSequence action?

徽标-> runAction(CCSequence :: create(CCDelayTime :: create(1.4)，CCEaseBounceOut :: create(CCMoveTo :: create(1.4，ccd(254,787))))，CCRepeat :: create(CCSequence :: create(CCRotateTo :: create(1.3，-3)，CCRotateTo :: create(1.3，6)，NULL)，100)，NULL));

logo->runAction(CCSequence::create(CCDelayTime::create(1.4),CCEaseBounceOut::create(CCMoveTo::create(1.4, ccd(254,787))),CCRepeat::create(CCSequence::create(CCRotateTo::create(1.3, -3),CCRotateTo::create(1.3, 6),NULL), 100),NULL));

推荐答案

传递空值只是为了告诉列表结束位置.用于终止序列.如果您未在序列末尾传递null，则您的应用可能会在设备上崩溃.

Null is passed just to tell where the list ends. used to terminate the sequence. if you don't pass null at end of sequence your app may crash on device.
