本文介绍如何使用Cocos2d-x中的SimpleAudioEngine进行背景音乐及音效的加载与控制，包括播放、暂停、停止、调整音量等操作，并提供示例代码。

一：在.cpp中添加头文件
//cpp with cocos2d-x
#include"SimpleAudioEngine.h"

二：在init()里添加背景音乐
//cpp with cocos2d-x
CocosDenshion::SimpleAudioEngine::sharedEngine()->playBackgroundMusic(
"background-music-aac.wav",true);

三：添加特效：
//cpp with cocos2d-x
CocosDenshion::SimpleAudioEngine::sharedEngine()->playEffect(
"pew-pew-lei.wav");

四：还有一些其他操作，包括pause，stop等：
backGround：
// stop background music
case 1:
SimpleAudioEngine::sharedEngine()->stopBackgroundMusic();
break;
// pause background music
case 2:
SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();
break;
// resume background music
case 3:
SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic();
break;
// rewind background music
case 4:
SimpleAudioEngine::sharedEngine()->rewindBackgroundMusic();
break;
Effect：
// stop effect
case 8:
SimpleAudioEngine::sharedEngine()->stopEffect(m_nSoundId);
break;
// unload effect
case 9:
SimpleAudioEngine::sharedEngine()->unloadEffect(std::string(CCFileUtils::sharedFileUtils()->fullPathFromRelativePath(EFFECT_FILE)).c_str());
break;
// add bakcground music volume
case 10:
SimpleAudioEngine::sharedEngine()->setBackgroundMusicVolume(SimpleAudioEngine::sharedEngine()->getBackgroundMusicVolume() + 0.1f);
break;
// sub backgroud music volume
case 11:
SimpleAudioEngine::sharedEngine()->setBackgroundMusicVolume(SimpleAudioEngine::sharedEngine()->getBackgroundMusicVolume() - 0.1f);
break;
// add effects volume
case 12:
SimpleAudioEngine::sharedEngine()->setEffectsVolume(SimpleAudioEngine::sharedEngine()->getEffectsVolume() + 0.1f);
break;
// sub effects volume
case 13:
SimpleAudioEngine::sharedEngine()->setEffectsVolume(SimpleAudioEngine::sharedEngine()->getEffectsVolume() - 0.1f);
break;
case 14:
SimpleAudioEngine::sharedEngine()->pauseEffect(m_nSoundId);
break;
case 15:
SimpleAudioEngine::sharedEngine()->resumeEffect(m_nSoundId);
break;
case 16:
SimpleAudioEngine::sharedEngine()->pauseAllEffects();
break;
case 17:
SimpleAudioEngine::sharedEngine()->resumeAllEffects();
break;
case 18:
SimpleAudioEngine::sharedEngine()->stopAllEffects();

五：注意！
1、音乐格式要注意，像在pc机上wav，mp3是可以用的，ogg那是肯定不可以的。
2、开始播放音乐后，即使你切换场景，音乐还是在播放。所以需要在切换场景的同时把音乐关上。
