ExecuteInEditMode

描述

使脚本的所有实例都在编辑模式下执行。

默认情况下，仅在播放模式下执行 MonoBehaviour。 通过添加此属性，MonoBehaviour 任何实例的回调函数都将在 Editor 未处于播放模式时执行。

这些函数不像它们在播放模式下那样被不断调用。
- Update is only called when something in the scene changed.
- OnGUI is called when the Game View receives a non-editor-only Event that it does not use (e.g., EventType.ScrollWheel) and does not forward to the Editor's keyboard shortcut system (e.g., EventType.KeyDown, EventType.KeyUp). Events forwarded to the Game View are enqueued and are not guaranteed to be processed immediately.
- OnRenderObject and the other rendering callback functions are called on every repaint of the Scene View or Game View.

// The PrintAwake script is placed on a GameObject.  The Awake function is
// called when the GameObject is started at runtime.  The script is also
// called by the Editor.  An example is when the scene is changed to a
// different scene in the Project window.
// The Update() function is called, for example, when the GameObject transform
// position is changed in the Editor.
