    public static float AudioEffectVolumns = 1F;                     //音效音量

    private static Dictionary<string, AudioClip> _DicAudioClipLib;   //音訊庫

        _DicAudioClipLib = new Dictionary<string, AudioClip>();
        foreach (AudioClip audioClip in AudioClipArray){
            _DicAudioClipLib.Add(audioClip.name,audioClip);
        }
        //處理音訊源
        _AudioSourceArray=this.GetComponents<AudioSource>();
        _AudioSource_BackgroundAudio = _AudioSourceArray[0];
        _AudioSource_AudioEffectA = _AudioSourceArray[1];
        _AudioSource_AudioEffectB = _AudioSourceArray[2];

        //從資料持久化中得到音量數值

        }
	}//Start_end

    /// <summary>

        {
            PlayAudioEffectB(_DicAudioClipLib[strAudioEffctName]);
        }
        else
        {

        //資料持久化
        PlayerPrefs.SetFloat("AudioEffectVolumns", floAudioEffectVolumns);
    }
}//Class_end

 

二、該“音訊管理器”指令碼的使用方法

①在專案的層級檢視中新建一個空物件"_AudioManager" 

②把AudioManager.cs指令碼賦值給空物件“_AudioManager”

③拖拽檢視中的音效剪輯檔案到對應的引數列表中，

④在專案中新增“音訊監聽（Audio Listener）”與3個“音訊源(Audio Sources)”元件即可
