拓展自定义编辑器窗口(EditorGUILayout类)

比眉伴天荒 2022-12-10 05:00 186阅读 0赞

对于编辑器中的GUI系统，我们可以分为四大类：

1、UnityEngine.GUI

2、UnityEngine.GUILayout **（最常用） **

3、UnityEditor.EditorGUI

4、UnityEditor.EditorGUILayout

Unity支持自行创建窗口，也支持自定义窗口布局**。 **

EditorGUILayout类是带自动布局的EditorGUI系统，所属命名空间UnityEditor，用其绘制的所有控件都带有自动布局效果，跟GUILayout系统的差别是其拥有部分编辑器专用控件，且其只能运行在编辑器内，自适应性较强，但开发自由度较低。

注意：**EditorGUILayout系统不可以在发布后使用，只能在编辑器中使用**。

在Project视图中创建一个Editor文件夹，在文件夹中再创建一条脚本。

自定义窗口需要让脚本**继承EditorWindow再设置MenuItem**，此时在Unity导航菜单栏中GameObjec->window就可创建一个自定义窗口。

**0.窗口：**

using UnityEngine;
    using UnityEditor; //引入编辑器命名空间
    public class MyEditor:EditorWindow
    {
        [MenuItem("GameObject/caymanwindow")]
        static void AddWindow()
        {
            //创建窗口
            Rect wr = newRect(0,0,500,500);
            //另一种方式：myEditor window = (myEditor)EditorWindow.GetWindow(typeof(myEditor), true, "cayman");
            MyEditor window = (MyEditor)EditorWindow.GetWindowWithRect(typeof(MyEditor),wr,true,"widow name");
            window.Show();
        }
    
        //[MenuItem("GameObject/caymanwindow", true)]   //如果没有选择物体，禁用菜单
        //static bool ValidateSelection() 
        //{
        //    return Selection.activeGameObject != null;
        //}
    }

**1.LabelField制作一个标签字段(通常用于显示只读信息)**

LabelField(string label1,string label2,GUILayoutOption\[\] options)

//参数：label1标签字段前面的标签  label2显示在右侧的标签  options额外布局属性可选列表  --无返回值

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 6 7 8 9 10 11 12 13 14 </td> 
 <td> <code>public class myEditor3 :EditorWindow{ </code> <code>//在编辑器显示一个标签，带有自编辑器开始的秒数</code> <code>[MenuItem(</code><code>"cayman/tempShow"</code><code>)]</code> <code>static void newWelcome()</code> <code>{ </code> <code>myEditor3 window3 =(myEditor3)EditorWindow.GetWindow(</code><code>typeof</code><code>(myEditor3),</code><code>true</code><code>,</code><code>"Eam"</code><code>);</code> <code>window3.Show();</code> <code>}</code> <code>voidOnGUI()</code> <code>{ </code> <code>EditorGUILayout.LabelField(</code><code>"Time since start: "</code><code>,EditorApplication.timeSinceStartup.ToString());</code> <code>this</code><code>.Repaint();</code><code>//实时刷新</code> <code>}</code> <code>}</code> </td> 
 </tr> 
 </tbody>
