@H_403_0@接着看教程：播放音乐与音效，然后想实现一个播放，暂停，停止的小功能，就附加看了一下Menu的一些知识，又回顾了一下坐标系

@H_403_0@音乐和音效的播放主要使用的SimpleAudioEngine，目前看3.x里面SimpleAudioEngine的注释没有说depart，所以应该和2.x是一直的。

@H_403_0@1、先导入头文件和命名空间

#include <SimpleAudioEngine.h>

using namespace CocosDenshion;

2、SimpleAudioEngine::getInstance()初始化AudioEngine,在Scene的init中调用

	SimpleAudioEngine::getInstance()->preloadBackgroundMusic(BG_MUSIC);
	SimpleAudioEngine::getInstance()->preloadEffect(DOG_WANGWANG);

预加载音频文件 @H_403_0@3、然后在相应的事件处理中，就可以调用相关方法，比如：

SimpleAudioEngine::getInstance()->playBackgroundMusic(BG_MUSIC,true);
dog_wangwang = SimpleAudioEngine::getInstance()->playEffect(DOG_WANGWANG);
SimpleAudioEngine::getInstance()->resumeBackgroundMusic();
SimpleAudioEngine::getInstance()->resumeEffect(dog_wangwang);
	if (SimpleAudioEngine::getInstance()->isBackgroundMusicPlaying()){
		SimpleAudioEngine::getInstance()->pauseBackgroundMusic();
	}
	if (dog_wangwang > 0){
		SimpleAudioEngine::getInstance()->pauseEffect(dog_wangwang);
	}
	SimpleAudioEngine::getInstance()->stopBackgroundMusic(true);
	SimpleAudioEngine::getInstance()->stopAllEffects();

还有一些方法，可以查看定义。 @H_403_0@

@H_403_0@Menu继承关系如图：

@H_403_0@

@H_403_0@简单使用

    auto playBgMusic = MenuItemFont::create("Paly BgMusic",CC_CALLBACK_1(HelloWorld::menuPlayBgMusicCallback,this));
    playBgMusic->setPosition(Vec2(visibleSize.width / 5,visibleSize.height / 6));

    // create menu,it's an autorelease object
    auto menu = Menu::create(closeItem,playBgMusic,playEffect,pause,resume,stop,NULL);
    menu->setPosition(Vec2::ZERO);
    this->addChild(menu,1);

void HelloWorld::menuPlayBgMusicCallback(Ref* pSender){
    SimpleAudioEngine::getInstance()->playBackgroundMusic(BG_MUSIC,true);
}
