4.0创建编辑器窗体EditorWindow

编辑器窗体类都需要继承自EditorWindow类，代码中有详细注释：

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

public class MyEditorWindow : EditorWindow
{
    public static MyEditorWindow instance;
    //TextField
    private string textField = "textField";
    //TextArea
    private string textArea = "这是一个textArea,可以用来多行输入文本\ntextArea1\ntextArea2";
    //ScrollView相关变量
    private Vector2 scrolViewPos=Vector2.zero;
    //Toolbar相关变量
    private List<string> listToolbar = new List<string>()
    {
        "tab0",
        "tab1",
        "tab2",
        "tab3"
    };
    private int indexToolbar = 0;
    //enum
    private enum EnumPopup
    {
        EnumPopup0,
        EnumPopup1,
        EnumPopup2
    }
    private EnumPopup selectedEnumPopup;
    //各种类型
    private int intField = 0;
    private float floatField = 1.0f;
    private Texture2D texture2DField;
    private Vector3 vector3Field;
    private Color colorField;
    private Animation animationField;

    //菜单路径后，可以添加快捷键如#_y，具体含义请看下图
    [MenuItem("Tools/ShowMyEditorWindow #_y")]
    public static void ShowWindow()
    {
        instance = EditorWindow.GetWindow<MyEditorWindow>();
        instance.titleContent = new GUIContent("MyEditorWindow");
    }

    private void OnEnable()
    {
        Debug.Log("OnEnable");
    }

    public void OnDisable()
    {
        Debug.Log("OnDisable");
    }

    private void OnGUI()
    {
        //文本框LabelField 字体加粗
        EditorGUILayout.LabelField("这是一个EditorGUILayout.LabelField",EditorStyles.boldLabel);
        //textField
        textField = EditorGUILayout.TextField("这是一个TextField",textField);
        //TextArea
        textArea = EditorGUILayout.TextArea(textArea);
        //Box
        GUILayout.Box("这是一个Box");
        //tab按钮
        indexToolbar = GUILayout.Toolbar(indexToolbar, listToolbar.ToArray());
        //scrolView 宽300，高200
        scrolViewPos = GUILayout.BeginScrollView(scrolViewPos,GUILayout.Width(300),GUILayout.Height(200));
        //grid Layout
        //AssetPreview.GetAssetPreview()用于生成资源的预览图
        Texture2D preview = AssetPreview.GetAssetPreview(Resources.Load<GameObject>("Player"));
        List<GUIContent> guiContents = new List<GUIContent>();
        for (int i = 0; i < 13; i++)
        {
            GUIContent guiContent = new GUIContent();
            guiContent.text ="tab"+indexToolbar+" item"+i;
            guiContent.image = preview;
            guiContents.Add(guiContent);
        }
        GUIStyle guiStyle = new GUIStyle(GUI.skin.button);
        guiStyle.alignment = TextAnchor.LowerCenter;
        guiStyle.imagePosition = ImagePosition.ImageAbove;
        guiStyle.fixedWidth = 80;
        guiStyle.fixedHeight = 90;
        int selectionGridIndex = -1;
        selectionGridIndex = GUILayout.SelectionGrid(selectionGridIndex,guiContents.ToArray(), 5, guiStyle);
        if(selectionGridIndex!=-1)
            Debug.Log("选中了tab"+indexToolbar+" Item"+selectionGridIndex);
        GUILayout.EndScrollView();
        //Button
        if (GUILayout.Button("Button"))
        {
            Debug.Log("我是一个Button");
        }
        //水平
        EditorGUILayout.BeginHorizontal();
        GUILayout.Button("HorizontalButton");
        GUILayout.Button("HorizontalButton");
        GUILayout.Button("HorizontalButton");
        EditorGUILayout.EndHorizontal();
        //垂直
        EditorGUILayout.BeginVertical();
        GUILayout.Button("VerticalButton");
        GUILayout.Button("VerticalButton");
        GUILayout.Button("VerticalButton");
        EditorGUILayout.EndHorizontal();
        //EnumPopup
        selectedEnumPopup =(EnumPopup) EditorGUILayout.EnumPopup("EnumPopup", selectedEnumPopup);
        //三种帮助框
        EditorGUILayout.HelpBox("Warning HelpBox", MessageType.Info);
        EditorGUILayout.HelpBox("Warning HelpBox", MessageType.Warning);
        EditorGUILayout.HelpBox("Warning HelpBox", MessageType.Error);
        //int
        intField = EditorGUILayout.IntField("IntField", intField);
        //float
        floatField = EditorGUILayout.FloatField("FloatField", floatField);
        //object
        texture2DField =
            (Texture2D) EditorGUILayout.ObjectField("ObjectField", texture2DField, typeof(Texture2D), true);
        vector3Field = EditorGUILayout.Vector3Field("Vector3Field", vector3Field);
        GUIContent guiContent1 = new GUIContent();
        guiContent1.text = "ColorField";
        guiContent1.tooltip = "这是一个ColorField";
        colorField = EditorGUILayout.ColorField(guiContent1, colorField);
        animationField =
            (Animation) EditorGUILayout.ObjectField("ObjectField", animationField, typeof(Animation), true);
    }
    //1秒100次
    private void Update()
    {
        
    }

    private void OnDestroy()
    {
        Debug.Log("OnDestroy");
    }      
}

如图该自定义EditorWindow效果：
