【Cocos2DX 】初窥门径（9）播放音乐/音效

Cocos2D对音乐/音效播放的封装已经很好了，下边是例子：

定义2个文件：

#define MUSIC_FILE        "LOLBgMusic.mp3"
#define EFFECT_FILE		 "Attack.wav"

在初始化的时候预加载音乐/音效文件：

//预加载
	CocosDenshion::SimpleAudioEngine::sharedEngine()->preloadBackgroundMusic(MUSIC_FILE);
	CocosDenshion::SimpleAudioEngine::sharedEngine()->preloadEffect( EFFECT_FILE );
	//设置音量
	CocosDenshion::SimpleAudioEngine::sharedEngine()->setEffectsVolume(0.5);
	CocosDenshion::SimpleAudioEngine::sharedEngine()->setBackgroundMusicVolume(0.5);

播放：

		//循环播放背景音乐，
		CocosDenshion::SimpleAudioEngine::sharedEngine()->playBackgroundMusic(MUSIC_FILE,true);

		//播放音效
		CocosDenshion::SimpleAudioEngine::sharedEngine()->playEffect(EFFECT_FILE);

其他相关函数：

// stop background music
SimpleAudioEngine::sharedEngine()->stopBackgroundMusic();
 // pause background music
 SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();
// resume background music
SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic();
// rewind background music
SimpleAudioEngine::sharedEngine()->rewindBackgroundMusic();
// is background music playing
SimpleAudioEngine::sharedEngine()->isBackgroundMusicPlaying()
// add bakcground music volume
SimpleAudioEngine::sharedEngine()->setBackgroundMusicVolume(SimpleAudioEngine::sharedEngine()->getBackgroundMusicVolume() + 0.1f);


SimpleAudioEngine::sharedEngine()->pauseEffect(m_nSoundId);
SimpleAudioEngine::sharedEngine()->resumeEffect(m_nSoundId);
SimpleAudioEngine::sharedEngine()->pauseAllEffects();
SimpleAudioEngine::sharedEngine()->resumeAllEffects();
SimpleAudioEngine::sharedEngine()->stopAllEffects();
