coco2d-x关于CCArray存储动画不能调用的问题,求解释啊

Question

bool CCNewGame::init(){

this->getChildByTag(123)->runAction(this->m_pFlyAction);
this->getChildByTag(123)->runAction(CCMoveTo::create(moveDuration,p));
}

Answer 1

主要就是画面上一条龙,龙的动画一共有8个,正好向8个方向飞的动画,存储到了CCArry里面,在init()方法里面怎么用都可以,但是一到ccTouchEnd()里面就报错了,成员对象在ccTouch()里面可以调用啊,但是为什么内存溢出呢,可以调试通过,我一点画面,想飞行就停止运行,应该是内存的问题吧.求解答

Answer 2

应该是因为你在init里面创建的array没有retain， 你可以retain一下试试

Answer 3

对啊,没有申请内存空间,所以内存crash了,后来弄好了,今天才想起来提问了,结贴了哈~
