cocos2d-x的初步学习九

这篇文章中，我们简单介绍下cocos2dx中播放音乐的类，SimpleAudioEngine，游戏中音乐主要是背景音乐，跟短的音效，OK，直接上代码：

    //预加载
    SimpleAudioEngine::sharedEngine()->preloadBackgroundMusic("music_logo.mp3");
    
    //播放背景音乐
    SimpleAudioEngine::sharedEngine()->playBackgroundMusic("music_logo.mp3", true);
    
    //暂停播放
    SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();
    
    //停止播放，还有一个函数带一个参数，表示是否释放该资源
    SimpleAudioEngine::sharedEngine()->stopBackgroundMusic();
    
    //设置音量，0.0-1.0
    SimpleAudioEngine::sharedEngine()->setBackgroundMusicVolume(0.5);
    
    //播放音效
    SimpleAudioEngine::sharedEngine()->playEffect("sound_button.mp3");
    
    //暂停某个音效
    SimpleAudioEngine::sharedEngine()->pauseEffect(unsigned int nSoundId);
    
    //暂停全部音效
    SimpleAudioEngine::sharedEngine()->pauseAllEffects();
    
    //停止某个音效
    SimpleAudioEngine::sharedEngine()->stopEffect(unsigned int nSoundId);
    
    //停止所有音效
    SimpleAudioEngine::sharedEngine()->stopAllEffects();
    
    //在程序不需要音乐时，释放sharedEngine()
    SimpleAudioEngine::sharedEngine()->end();

OK，就这么简单呐～～～～
