cocos2d-x CC_SYNTHESIZE_READONLY

//定义一个只读属性Label，在类定义中可以使用this->getLabel来访问

    CC_SYNTHESIZE_READONLY(cocos2d::CCLabelTTF*,_label,Label);

 

CC_SYNTHESIZE_READONLY(varType, varName, funName)声明一个成员变量以及getfunName函数，没有set函数。getfunName已经实现，其实现就是返回这个值。

 

this->_layer = GameOverLayer::node();

this->_layer->retain();        

this->addChild(_layer);

 

 

bool GameOverLayer::init()

    {

        CCSize winSize = CCDirector::sharedDirector()->getWinSize();

        this->_label = CCLabelTTF::labelWithString("","Artial",32);

        this->_label->retain();

        this->_label->setColor(ccc3(0,0,0));

        this->_label->setPosition(ccp(winSize.width/2,winSize.height/2));

        this->addChild(this->_label);

 

        this->runAction(CCSequence::actions(CCDelayTime::actionWithDuration(3),
