void
preloadBackgroundMusic(

);
//预加载
playBackgroundMusic(
,
bool
bLoop=
false
//播放，是否循环，默认不循环
stopBackgroundMusic(
bReleaseData=
//停止，是否释放音乐资源
pauseBackgroundMusic();
//暂停
resumeBackgroundMusic();
//恢复
rewindBackgroundMusic();
//重播
//返回是否将要播放背景音乐
willPlayBackgroundMusic();
//返回是否正在播放背景音乐
//注意：暂停也算正在播放，只有停止了才算未播放。
isBackgroundMusicPlaying();
//设置音量，取值范围0~1.0
//查看了内部源码，发现音量的设置没有实现，即音量永远是1.0
float
getBackgroundMusicVolume();
setBackgroundMusicVolume(
volume);
5、音效的函数

preloadEffect(
unsigned
int
playEffect(
//播放，返回该音效的ID。是否循环
stopEffect(unsigned
nSoundId);
//停止指定ID的音效
stopAllEffects();
//停止所有音效
pauseEffect(unsigned
//暂停指定ID的音效
pauseAllEffects();
//暂停所有音效
@H_987_301@
resumeEffect(unsigned
//恢复指定ID的音效
resumeAllEffects();
//恢复所有音效
unloadEffect(
const
char
*pszFilePath);
//卸载音效资源
getEffectsVolume();
setEffectsVolume(

7、关于音量调节

SimpleAudioEngine::getBackgroundMusicVolume()
{
return
1.0;
}
SimpleAudioEngine::setBackgroundMusicVolume(
volume)
{
}
@H_987_301@
SimpleAudioEngine::getEffectsVolume()
{
1.0;
}
SimpleAudioEngine::setEffectsVolume(
volume)
{
