public float default_width= 720;
public float default_height= 480;
public float audioSFXSliderValue;
public float audioMusicSliderValue;
public float graphicsSliderValue;
private int detailLevels= 6;
void Start()

} else {
audioSFXSliderValue= 1;
}
if(PlayerPrefs.HasKey(gamePrefsName+"_MusicVol"))
{
audioMusicSliderValue= PlayerPrefs.
GetFloat(gamePrefsName+"_MusicVol");
} else {

}
if(PlayerPrefs.HasKey(gamePrefsName+"_GraphicsDetail"))
