Why Null is passed in CCSequence action?
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));
回答1:
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.
