    bg->setScale(0.5);
    bg->setPosition( ccp(size.width/2, size.height/2) );
    this->addChild(bg, 0,0);

菜单按钮及其效果，单击事件

CCMenuItemImage *newGameItem = CCMenuItemImage::create("newGameA.png", "newGameB.png",this,menu_selector(GameMenu::menuNewGameCallback)); //NEW GAME
    newGameItem->setScale(0.5);
    newGameItem->setPosition(ccp(size.width / 2 + 40,size.height / 2 - 20));
    newGameItem->setEnabled(false);	//暂不可见
    CCMenuItemImage *continueItem = CCMenuItemImage::create("continueA.png", "continueB.png",this,menu_selector(GameMenu::menuContinueCallback));  //CONTINUE
    continueItem->setScale(0.5);
    continueItem->setPosition(ccp(size.width / 2 + 40,size.height / 2 - 60));
    continueItem->setEnabled(false);
    CCMenuItemImage *aboutItem = CCMenuItemImage::create("aboutA.png", "aboutB.png",this,menu_selector(GameMenu::menuAboutCallback));  //About
    aboutItem->setScale(0.5);
    aboutItem->setPosition(ccp(size.width / 2 + 40,size.height / 2 - 100));
    aboutItem->setEnabled(false);
    soundItem = CCMenuItemImage::create("sound-off-A.png", "sound-off-B.png",this,menu_selector(GameMenu::menuSoundCallback)); //声音
    soundItem->setScale(0.5);
    soundItem->setEnabled(false);
    soundItem->setPosition(ccp(40,40));
    CCMenu* mainmenu = CCMenu::create(newGameItem,continueItem,aboutItem,soundItem,NULL);
    mainmenu->setPosition(ccp(0,0));
    this->addChild(mainmenu,1,3);
    issound = false;

进入该场景动画，菜单按钮由小至大缩放，并显示菜单

void GameMenu::onEnter(){
    CCLayer::onEnter();
    CCSize size = CCDirector::sharedDirector()->getWinSize();
    CCNode* mainmenu = this->getChildByTag(3);
    mainmenu->setScale(0);
    mainmenu->runAction(CCSequence::create(CCScaleTo::create(0.5,1),CCCallFuncN::create(this, callfuncN_selector(GameMenu::menuEnter)),NULL));
}
void GameMenu::menuEnter(CCNode* pSender ){
    CCNode* mainmenu = this->getChildByTag(3);
    CCArray* temp = mainmenu->getChildren();
    for(int i = 0;i < temp->count();i ++)
        ((CCMenuItemImage *)temp->objectAtIndex(i))->setEnabled(true);
}
