SimpleAudioEngine::sharedEngine()->playBackgroundMusic("sound/game_music.mp3",true);//开始播放背景音乐，true表示循环
SimpleAudioEngine::sharedEngine()->stopBackgroundMusic();//停止背景音乐，这是一个缺省参数函数，传参表示是否释放音乐文件
SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();//暂停背景音乐
SimpleAudioEngine::sharedEngine()->rewindBackgroundMusic();//重头调用背景音乐
SimpleAudioEngine::sharedEngine()->isBackgroundMusicPlaying()//返回布尔型参数，表示是否在放着背景音乐
SimpleAudioEngine::sharedEngine()->setBackgroundMusicVolume(0.5);//设置音量0.0-1.0
