Unity3D使用NGUI制作简易弹出窗口声音控制器

这里常州手游开发-幻天网络要和大家分享下使用NGUI制作弹出窗口声音控制器的内容，想要制作一个简单的声音控制器，可以采取弹处窗口的形式来制作，弹出窗口被做成预设体，点击设置的时候加载，再次点击时销毁内存中的预设体克隆对象；

使用单例来控制弹出窗口实例的唯一性。

代码：

//控制声音的单例类

using System.Collections;

public class BackgroundMusicMag ｛

    #region 

    private AudioSource bgm;

    private static AudioSource audio;

    private static BackgroundMusicMag bgmObj;

    private static bool IsPlay;

    //静态函数中只能调用静态数据成员

    #endregion

    private BackgroundMusicMag()｛｝

    public static BackgroundMusicMag GetInstance() ｛

        if (bgmObj == null) ｛

            bgmObj = new BackgroundMusicMag();

            audio = GameObject.Find("musicFile").GetComponent<AudioSource>();

            IsPlay = true;

        ｝

        return bgmObj;

    ｝

    public void SetVol(float vol) ｛

        if(audio != null) ｛

            audio.volume = vol;

        ｝

    ｝

    public float GetVol() ｛

        return audio.volume;

    ｝

    public void SetPit(float pit) ｛

        if (audio != null) ｛

            audio.pitch = pit;

        ｝

    ｝

    public float GetPit() ｛

        return audio.pitch;

    ｝

    public void ChangeAudioPlayStatus() ｛

        if (IsPlay) ｛

            audio.Pause();

            Debug.Log("Pause");

        ｝ else ｛

            audio.UnPause();

            Debug.Log("UnPause");

        ｝

        IsPlay = !IsPlay;

    ｝

｝

        windowCache.Add(windowName, prefabClone);

        return prefabClone;
