首先我們定義三種音效，….反正嘛，，，自己push進去幾種…
新建一個 AudioManager 類,這個類切換場景我們保持不銷燬，因為遊戲所有場景都會有聲音的存在…嗷嗚~~嗷嗚~~嗷嗚~~
遊戲中，一般我們播放一種背景音樂。以及 多種點擊多個button產生的不同點擊音效…等等
在遊戲設置中，我們可以設置音效大小以及關閉 (關閉==零嘛)
private static AudioManager audioManager;
public static AudioManager Instance { get { return audioManager; } }
//播放聲音的組件…都懂的
private AudioSource audioSource;
//聲音的類型，以及路徑。這個類型如果覺得一個Type不夠，自己可以按需求加。

//緩存音頻文件，下次可以直接用，不需要再加載
private Dictionary<AudioType, AudioClip> audioClipDic;

//使用中的，音頻組件

//音效的音量
private float soundVolume = 1;
//音樂音量 用於本地讀取PlayerPrefs
