控制器中的功能并不多，主要是以下这些

//对玩家分数的操作	CC_SYNTHESIZE_READONLY(SaveData *, m_saveData, SaveData);	void update(float tm);	//游戏暂停与恢复	void menuPauseCallback(cocos2d::Ref* pSender);	//声音控制	void menuMusicCallback(cocos2d::Ref* pSender);

以下是这些功能的实现

bool Controller::init(){	if (!Layer::init())	{		return false;	}	bool bRect = false;		do 	{		Size winSize = Director::getInstance()->getWinSize();		//从xml文件里读取中文显示出来		auto dictionary = Dictionary::createWithContentsOfFile("fonts/AboutMe.xml");		score_label = Label::createWithTTF(			((__String *)(dictionary->objectForKey("score")))->getCString(),			"fonts/DFPShaoNvW5-GB.ttf",			25);		score_label->setPosition(score_label->getContentSize().width / 2,			winSize.height - score_label->getContentSize().height * 2);		CC_BREAK_IF(!score_label);		this->addChild(score_label);		//加入显示分数的标签		m_saveData = SaveData::create();		//这里一定要retain一下saveData。在析构函数中release一下		m_saveData->retain();		auto str = __String::createWithFormat("%d", m_saveData->getScore());		m_score = Label::createWithTTF(str->getCString(), "fonts/DFPShaoNvW5-GB.ttf", 25);		m_score->setPosition(Point(score_label->getContentSize().width + m_score->getContentSize().width / 2 + 30,			winSize.height - score_label->getContentSize().height * 2));		CC_BREAK_IF(!m_score);		this->addChild(m_score);		//记得更新分数的显示		this->scheduleUpdate();		//游戏声音控制按钮		Sprite *normalMusic = Sprite::createWithSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("game_musicPause.png"));		Sprite *pressedMusic = Sprite::createWithSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("game_musicPause.png"));		pMusicItem = MenuItemSprite::create(			normalMusic,			normalMusic,			NULL,			CC_CALLBACK_1(Controller::menuMusicCallback, this));		//游戏暂停按钮		Sprite *normalPause = Sprite::createWithSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("game_resume_nor.png"));		Sprite *pressedPause = Sprite::createWithSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("game_resume_pressed.png"));		pPauseItem = MenuItemSprite::create(			normalPause,			pressedPause,			NULL,			CC_CALLBACK_1(Controller::menuPauseCallback, this));		Menu *menuPause = Menu::create(pMusicItem,pPauseItem, NULL);		menuPause->alignItemsHorizontallyWithPadding(pPauseItem->getContentSize().width/2);		menuPause->setPosition(			Point(winSize.width - pPauseItem->getContentSize().width*2, winSize.height - normalPause->getContentSize().height));		this->addChild(menuPause);	} while (0);	return true;}//游戏暂停void Controller::menuPauseCallback(cocos2d::Ref* pSender){	CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("sound/button.mp3");	if (!Director::getInstance()->isPaused())	{		// 图标状态设置		pPauseItem->setNormalImage(Sprite::createWithSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("game_pause_nor.png")));		pPauseItem->setSelectedImage(Sprite::createWithSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("game_pause_press.png")));		CocosDenshion::SimpleAudioEngine::getInstance()->pauseBackgroundMusic(); // 停止背景音乐		CocosDenshion::SimpleAudioEngine::getInstance()->stopAllEffects(); // 停止全部的特效		Director::getInstance()->pause(); // 停止全部的动作，敌机飞行，子弹前进等	}	else	{		pPauseItem->setNormalImage(Sprite::createWithSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("game_resume_nor.png")));		pPauseItem->setSelectedImage(Sprite::createWithSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("game_resume_pressed.png")));		CocosDenshion::SimpleAudioEngine::getInstance()->resumeBackgroundMusic();// 恢复		Director::getInstance()->resume(); // 恢复	}}void Controller::menuMusicCallback(cocos2d::Ref* pSender){	CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("sound/button.mp3");	if (CocosDenshion::SimpleAudioEngine::getInstance()->isBackgroundMusicPlaying())	{		// 图标状态设置		pMusicItem->setNormalImage(Sprite::createWithSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("game_music.png")));		pMusicItem->setSelectedImage(Sprite::createWithSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("game_music.png")));		CocosDenshion::SimpleAudioEngine::getInstance()->stopBackgroundMusic(); // 停止背景音乐//		CocosDenshion::SimpleAudioEngine::getInstance()->stopAllEffects(); // 停止全部的特效	}	else	{		pMusicItem->setNormalImage(Sprite::createWithSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("game_musicPause.png")));		pMusicItem->setSelectedImage(Sprite::createWithSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName("game_musicPause.png")));		CocosDenshion::SimpleAudioEngine::getInstance()->playBackgroundMusic("sound/BackgroundMusic.mp3", true);// 恢复//		CocosDenshion::SimpleAudioEngine::getInstance()->resumeAllEffects();	}}void Controller::update(float tm){	auto str = __String::createWithFormat("%d", m_saveData->getScore());	//更新分数和坐标	m_score->setColor(Color3B(255, 0, 0));	m_score->setString(str->getCString());	m_score->setPositionX(score_label->getContentSize().width + m_score->getContentSize().width / 2 + 30);}

要实现游戏的暂停功能，能够直接将当前执行的场景暂停，而要实现声音的暂停。通过简单的停止背景音乐、音效却不行。

由于不断有新的子弹在发射、新的敌机在爆炸等。所以，我使用的方法是 将背景音乐与其它音效绑定。

比方以下子弹类中的代码

if (CocosDenshion::SimpleAudioEngine::getInstance()->isBackgroundMusicPlaying())	{		CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("sound/bullet.wav");	}

仅仅有背景音乐处于播放状态，音效才会播放。

尽管功能实现了，只是总感觉方法太水了。。。谁有更好的方式欢迎告知。
