#defineEFFECT_FILE "effect1.wav"//音效

#define MUSIC_FILE "background.mp3"//音乐

这两个宏代表了音乐和音效的名称或者目录

SimpleAudioEngine::sharedEngine()->preloadBackgroundMusic(CCFileUtils::sharedFileUtils()->fullPathFromRelativePath(MUSIC_FILE));//缓存音乐

SimpleAudioEngine::sharedEngine()->preloadEffect(CCFileUtils::sharedFileUtils()->fullPathFromRelativePath(EFFECT_FILE));//缓存音效

//set default volume

SimpleAudioEngine::sharedEngine()->setEffectsVolume(0.5);//设置音效声音

SimpleAudioEngine::sharedEngine()->setBackgroundMusicVolume(0.5);//设置音乐声音

1.播放背景音乐

SimpleAudioEngine::sharedEngine()->playBackgroundMusic(std::string(CCFileUtils::sharedFileUtils()->fullPathFromRelativePath(MUSIC_FILE)).c_str(),true);

2.也可以判断目前有没有背景音乐

if (SimpleAudioEngine::sharedEngine()->isBackgroundMusicPlaying())

{

CCLOG("背景音乐正在播放");

}

else

{

CCLOG("没有背景音乐播放");

}

3.停止背景音乐

SimpleAudioEngine::sharedEngine()->stopBackgroundMusic();

4.暂停背景音乐

SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();

5.恢复背景音乐

SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic();

6.重头调用背景音乐

SimpleAudioEngine::sharedEngine()->rewindBackgroundMusic();

音效部分

1.播放音效

m_nSoundId = SimpleAudioEngine::sharedEngine()->playEffect(std::string(CCFileUtils::sharedFileUtils()->fullPathFromRelativePath(EFFECT_FILE)).c_str());

2.重复播放音效

m_nSoundId = SimpleAudioEngine::sharedEngine()->playEffect(std::string(CCFileUtils::sharedFileUtils()->fullPathFromRelativePath(EFFECT_FILE)).c_str(),true);

3.停止播放音效

SimpleAudioEngine::sharedEngine()->stopEffect(m_nSoundId);

4.卸载音效

SimpleAudioEngine::sharedEngine()->unloadEffect(std::string(CCFileUtils::sharedFileUtils()->fullPathFromRelativePath(EFFECT_FILE)).c_str());

5.暂停音效

SimpleAudioEngine::sharedEngine()->pauseEffect(m_nSoundId);

6.恢复音效

SimpleAudioEngine::sharedEngine()->resumeEffect(m_nSoundId);

7.暂停所有音效

SimpleAudioEngine::sharedEngine()->pauseAllEffects();

8.恢复所有音效

SimpleAudioEngine::sharedEngine()->resumeAllEffects();

9.停止所有音效

SimpleAudioEngine::sharedEngine()->stopAllEffects()
