EditorWindow

编辑器的功能扩展，自定义一个编辑器窗口

实现步骤，新建一个C#类，继承与EditorWindow，在OnGUI方法中绘制UI，再设置一个触发窗口的方法

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;

public class MyWindow : EditorWindow {

    string myString = "Hello world";
    bool groupEnabled;
    bool myBool = true;
    float myFloat = 1.23f;

    [MenuItem("Window/My Window")]
    public static void showWindow() {
        EditorWindow.GetWindow (typeof(MyWindow));
    }

    void OnGUI() {
        GUILayout.Label ("Base Settings", EditorStyles.boldLabel);
        myString = EditorGUILayout.TextField ("Text Field", myString);

        groupEnabled = EditorGUILayout.BeginToggleGroup ("Optional Setting", groupEnabled);
        myBool = EditorGUILayout.Toggle ("Toggle", myBool);
        myFloat = EditorGUILayout.Slider ("Slider", myFloat, -3, 3);
        EditorGUILayout.EndToggleGroup ();
    }
}

编译，然后回到Unity编辑器，这样就可以看到自己定义的窗口了
