U3D MonoBehaviour

一、简介　　

　　MonoBehaviour是每个脚本派生类的基类，它定义了一个脚本文件从最初被加载到最终被销毁的一个完整过程。

　　这个过程通过对应的方法体现出来，在不同的方法完成不同的功能，我们把这些方法称为：脚本生命周期相关的方法。包含内容有：

　　Awake()：当该脚本实例被载入时Awake被调用。（只会被调用一次）

　　OnEable()：当对象被启用并激活状态时此函数被调用。

　　Start()：Start仅在当第一次脚本启用Update方法被调用之前调用。（只会被调用一次）

　　Update()：当MonoBehaviour启用时，其Update在每一帧被调用

　　FixedUpdate()：（固定更新）会按照设置的时间固定频率来循环更新

　　LateUpdate()：LateUpdate是在所有Update函数调用后被调用。这可用于调整脚本执行顺序。例如:当物体在Update里移动时，跟随物体的相机可以在LateUpdate里实现。

　　OnGUI()：渲染和处理GUI事件时调用。

　　OnDisable()：当对象变为不可用或非激活状态时此函数被调用。

　　OnEnable()：当对象被启用并激活状态时此函数被调用。
