unity editorwindow

Unity Editor Window

**EditorGUILayout：**提供Unity内置类或结构体的布局组件，能够实现在Inspcctor和EditorWindow中自定义编辑器。

EditorGUILayout是对GUILayout的扩展，它主要用于Inspector和EditorWindow。

EditorGUI是Fixed排列，EditorGUILayout则是Automatic；

基本控件

所提供的控件多以Field为后缀，主要用于属性字段

1.数值输入控件
FloatFiled / IntFiled/ Vector2Field / Vector2IntField / Vector3Field / Vector3IntField / Vector4Field / RectField

float sizeMultiplier = EditorGUILayout.FloatField("Increase scale by:", sizeMultiplier);

  • 1

滑动条：FloatSlider() / IntSlider()：数值的输入

cloneTimesX = EditorGUILayout.IntSlider(cloneTimesX, 1, 10);

  • 1

2.文本输入：String变量
TextArea / TextField / PasswordFiled

3.Lable
LabelField()：显示只读信息

EditorGUILayout.LabelField("Time since start: ",
            EditorApplication.timeSinceStartup.ToString());

  • 1
  • 2

4.Toggle：Bool型变量

isFPSOpen = EditorGUILayout.Toggle("Is OpenFPS",isFPSOpen);

  • 1

5.PropertyFiled()
用于自定义属性面板中，定义各个字段的布局；使用该函数就会根据属性来使用unity自动的布局；

EditorGUILayout.PropertyField(m_GameObjectProp, new GUIContent("Game Object"));

  • 1

6.ObjectField()
支持unity提供的各种类型的对象

source = EditorGUILayout.ObjectField(source, typeof(Object), true)

  • 1

7.一些类类型：Color、Curve等
ColorFiled / CurveFileld / TagFiled

8.其它常用类型
PasswordFiled /

组织控件

通常以Beginxxx()和Endxxx()形式成对出现，其代码包含的控件将被统一组织；

1.Group
将控件以分组形式排列（Group相当于一个Panel），当Group移动时，组内成员也会跟随；

BeginFadeGroup(float val) / EndFadeGroup() / BeginToggleGroup() / EndToggleGroup()

BeginFoldoutHeaderGroup(bool foldout,GUIContent,) / EndFoleoutHeaderGroup()

在EditorGUI中：BeginDisableGroup(bool) /

2.Horizontal / Vertical
管理控件的水平和竖直布局方式

3.ScrollView
管理滚动视图内的控件，BeginScrollView()和EndScrollView()

4.Space()
插入一个空行

具体用法：

标签 Label

GUILayout.Label("--------Label-------");

文本框 TextField

string myString = "";
myString = EditorGUILayout.TextField("TrackName", myString);

{
            "A", "B", "C",  "D", 
};

// 
for(int i = 0; i < resList.Count; i++)
{
    // 创建按钮
    if (GUILayout.Button(resList[i]))
    {
        // 根据文件名在Project下选中文件
        Selection.activeObject = AssetDatabase.LoadAssetAtPath<GameObject>(m_path+resList[i]);	}
}

// update
foreach (var filename in resList)
{
	if (GUILayout.Button(filename))
    {
		Selection.activeObject = AssetDatabase.LoadAssetAtPath<GameObject>(m_path+filename);
	}
}

Inspector 面板自定义 实例

1.基础类 – 使用默认布局

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
 
public class Player : MonoBehaviour
{
 
    public int id;
 
    public string playerName;
    public string backStory;
    public float health;
    public float damage;
 
    public float weaponDamage1, weaponDamage2;
 
    public string shoeName;
    public int shoeSize;
    public string shoeType;
 
    void Start()
    {
        health = ;
    }
}

2.编辑器扩展脚本 – 自定义布局

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
 
//CustomEditor(typeof()) 用于关联你要自定义的脚本
[CustomEditor(typeof(Player))]
//必须要让该类继承自Editor,且不需要导入UnityEditor程序集
public class PlayerInspector : Editor
{
 
    Player player;
    bool showWeapons;
 
    void OnEnable()
    {
        //获取当前编辑自定义Inspector的对象
        player = (Player)target;
    }
 
    //执行这一个函数来一个自定义检视面板
    public override void OnInspectorGUI()
    {
        //设置整个界面是以垂直方向来布局
        EditorGUILayout.BeginVertical();
 
        //空两行
        EditorGUILayout.Space();
        EditorGUILayout.Space();
 
        //绘制palyer的基本信息
        EditorGUILayout.LabelField("Base Info");
        player.id = EditorGUILayout.IntField("Player ID", player.id);
        player.playerName = EditorGUILayout.TextField("PlayerName", player.playerName);
 
        //空三行
        EditorGUILayout.Space();
        EditorGUILayout.Space();
        EditorGUILayout.Space();
 
        //绘制Player的背景故事
        EditorGUILayout.LabelField("Back Story");
        player.backStory = EditorGUILayout.TextArea(player.backStory, GUILayout.MinHeight());
 
        //空三行
        EditorGUILayout.Space();
        EditorGUILayout.Space();
        EditorGUILayout.Space();
 
        //使用滑块绘制 Player 生命值
        player.health = EditorGUILayout.Slider("Health", player.health, , );
 
        //根据生命值设置生命条的背景颜色
        if (player.health < )
        {
            GUI.color = Color.red;
        }
        else if (player.health > )
        {
            GUI.color = Color.green;
        }
        else

        }
 
        //指定生命值的宽高
        Rect progressRect = GUILayoutUtility.GetRect(, );
 
        //绘制生命条
        EditorGUI.ProgressBar(progressRect, player.health / 100.0f, "Health");
 
        //用此处理，以防上面的颜色变化会影响到下面的颜色变化
        GUI.color = Color.white;
 
        //空三行
        EditorGUILayout.Space();
        EditorGUILayout.Space();
        EditorGUILayout.Space();
 
        //使用滑块绘制伤害值
        player.damage = EditorGUILayout.Slider("Damage", player.damage, , );
 
        //根据伤害值的大小设置显示的类型和提示语
        if (player.damage < )
        {
            EditorGUILayout.HelpBox("伤害太低了吧！！", MessageType.Error);
        }
        else if (player.damage > )
        {
            EditorGUILayout.HelpBox("伤害有点高啊！！", MessageType.Warning);
        }
        else
        {
            EditorGUILayout.HelpBox("伤害适中！！", MessageType.Info);
        }
 
        //空三行
        EditorGUILayout.Space();
        EditorGUILayout.Space();
        EditorGUILayout.Space();
 
        //设置内容折叠
        showWeapons = EditorGUILayout.Foldout(showWeapons, "Weapons");
        if (showWeapons)
        {
            player.weaponDamage1 = EditorGUILayout.FloatField("Weapon 1 Damage", player.weaponDamage1);
            player.weaponDamage2 = EditorGUILayout.FloatField("Weapon 2 Damage", player.weaponDamage2);
        }
 
        //空三行
        EditorGUILayout.Space();
        EditorGUILayout.Space();
        EditorGUILayout.Space();
 
        //绘制鞋子信息
        EditorGUILayout.LabelField("Shoe");
        //以水平方向绘制
        EditorGUILayout.BeginHorizontal();
        EditorGUILayout.LabelField("Name", GUILayout.MaxWidth());
        player.shoeName = EditorGUILayout.TextField(player.shoeName);
        EditorGUILayout.LabelField("Size", GUILayout.MaxWidth());
