Unity编辑器扩展 Chapter3--Create Custom Inspector

一、Create Custom Inspector

重绘inspector面板一方面是我们的挂在脚本的窗口变得友好，另一方面可以让其变得更强大，比如添加一些有效性验证。

二、重要说明

1.EditorUtility.SetDirty(object target)：该方法可以表明target对象为dirty（(⊙﹏⊙)b，怎么翻译合适？）的，unity会将有dirty标记的已经改变的对象在磁盘中存储，可以用来对一些修改数据的强制刷新，这里用来立即绘制GUI（我们对GUI的修改不会立即生效，只有鼠标在Scene上时才会强制重绘界面元素）。

2.对于类似GUI.Style等静态属性的修改，在修改前需要备份，使用后在设回，避免修改后的对其他无需使用修改后属性的干扰。

3.布局中的GUILayout.BeginVertical等需成对出现，有始有终。

4.该类型的脚本都需放在Editor文件夹下，unity会自动调用。

三、Code

  2 using System.Collections;
  3 using UnityEditor;
  4 
  5 namespace RunAndJump.LeveCreator
  6 {
  7     //[CanEditMultipleObjects]  //希望多个挂在该类的对象可以在inspector面板选定多个一同修改的话
  8     //需要将该标签添加上，由于level类一个场景下只有一个，所以无需添加该标记
  9     [CustomEditor(typeof(Level))]
 10     public class LevelInspector : Editor
 11     {
 12         private Level _myTarget;
 13         private int _newTotalColumns;
