cocos2d-x CC_SYNTHESIZE

//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()

{

if(CCLayerColor::initWithColor(ccc4(255,255,255,255)))

{

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),

CCCallFunc::actionWithTarget(this,

callfunc_selector(GameOverLayer::gameOverDone)),NULL));

return true;

}

else

{

return false;
