一、簡介　　

　　MonoBehaviour是每個腳本派生類的基類，它定義了一個腳本文件從最初被加載到最終被銷毀的一個完整過程。

　　這個過程通過對應的方法體現出來，在不同的方法完成不同的功能，我們把這些方法稱為：腳本生命周期相關的方法。包含內容有：

　　Awake()：當該腳本實例被載入時Awake被調用。（只會被調用一次）

　　OnEable()：當對象被啟用并激活狀態時此函數被調用。

　　Start()：Start僅在當第一次腳本啟用Update方法被調用之前調用。（只會被調用一次）

　　Update()：當MonoBehaviour啟用時，其Update在每一幀被調用

　　FixedUpdate()：（固定更新）會按照設置的時間固定頻率來循環更新

　　LateUpdate()：LateUpdate是在所有Update函數調用后被調用。這可用于調整腳本執行順序。例如:當物體在Update里移動時，跟隨物體的相機可以在LateUpdate里實現。?

　　OnGUI()：渲染和處理GUI事件時調用。

　　OnDisable()：當對象變為不可用或非激活狀態時此函數被調用。

　　OnEnable()：當對象被啟用并激活狀態時此函數被調用。
