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。
