关于此函数->；cocos2d-x中的addChild（）

我是cocos2dx的新手，我刚刚开始写一些小游戏。我定义了一个名为Block的类，它继承自CCNode，它包含一个名为m_Block的CCSprite类。我通过函数addObjet（）将Block对象保存在CCArray m_runningBlock中

但是，当我试图从数组中取出CCSprite m_块，并通过函数this->addChilid（）将m_块添加到CCLayer时，出现了问题，我无法找出问题所在。有人能帮我吗

   class Block :public CCNode
    {
     public:
    int m_x;
    int m_y;
    CCSprite* m_block;  
     public:
    Block(void);
    Block(const char *pszFileName);
    ~Block(void);
    CCSprite* getSprite();
    void bindSprite(CCSprite* sprite);
    virtual bool init();
    CREATE_FUNC(Block);
     };
     //=====================================
       CCSprite* Block::getSprite(){
    return this->m_block;
      }

      void Block::bindSprite(CCSprite* sprite){
    this->m_block = sprite;
    this->addChild(m_block);

      }

      bool Block::init(){
    return true;
      }

     //=============================================

     CCArray* BlockManager::BlockType(Kind kind){
    Block* m_block1 = Block::create();
    m_block1->bindSprite(CCSprite::create("Block1.png"));
    Block* m_block2 = Block::create();
    m_block2->bindSprite(CCSprite::create("Block1.png"));
    Block* m_block3 = Block::create();
    m_block3->bindSprite(CCSprite::create("Block1.png"));
    Block* m_block4 = Block::create();
    m_block4->bindSprite(CCSprite::create("Block1.png"));
    CCArray* array = new CCArray;
    switch(kind){

    case A:
        m_block1->m_x = 4;
        m_block1->m_y = 14;
        m_block2->m_x = 5;
        m_block2->m_y = 14;
        m_block3->m_x = 5;
        m_block3->m_y = 13;
        m_block4->m_x = 5;
        m_block4->m_y = 12;

        array->addObject(m_block1);
        array->addObject(m_block2);
        array->addObject(m_block3);
        array->addObject(m_block4);
        break;
    }
    m_block1->release();
    m_block2->release();
    m_block3->release();
    m_block4->release();
    return array;
       }
      //=================================================

      bool BlockManager::init()
     {
    bool bRect=false;
    do {
        Kind kind = A;
        m_runingblock = CCArray::createWithCapacity(5);
        m_runingblock->retain();
        m_runingblock = BlockType(A);
        CCObject* obj=NULL;
        Block* block= NULL;
        CCSprite* sprite = NULL;
        CCARRAY_FOREACH(m_runingblock,obj){
            block = (Block*)obj;
            sprite = block->getSprite();
            sprite->setPosition(ccp(block->m_x*50,block->m_y*50));
            this->addChild(sprite);
        }
        this->scheduleUpdate();
        bRect=true;
    } while (0);
    return bRect;
        }

我可以从CCArray中获取m_x和m_y，但是当我尝试使用函数addChild（）时，会发生中断。

如果您有输入错误，应该是这个->addChild（sprite）；不是这个孩子（怨恨）；谢谢你的回答。
