Unity3D——MonoBehaviour api函数 调用时序剖析（From 圣典）

MonoBehaviour Mono行为

Inherits from
Behaviour
MonoBehaviour is the base class every script derives from.

MonoBehaviour是每个脚本的基类.

Using Javascript every script automatically derives from MonoBehaviour. When using C# or Boo you have to explicitly derive from MonoBehaviour.

每个Javascript脚本自动继承MonoBehaviour，使用C#或Boo时,需要显式继承MonoBehaviour.

Note: The checkbox for disabling a MonoBehavior (on the editor) will only prevent Start(), Awake(), Update(), FixedUpdate(), and OnGUI() from executing. If none of these functions are present, the checkbox is not displayed.

注意:MonoBehavior对象(编辑器中)的复选框，只有在其有Start()，Awake()，Update()， FixedUpdate()和 OnGUI()函数时显示，没有这些函数时则隐藏。(另注:译者在PC上Windows平台测试结果与此注释所描述情况不符)

Disabling this lets you skip the GUI layout phase.
