Unity编辑器扩展——自定义窗口

一：实现思路

Unity编辑器中的所有窗口的绘制都继承自EditorWindow类，并且需要引入UnityEditor的命名空间，使用类中的方法自定义任何所需的窗口

---

二：代码实现

——窗口Window

[MenuItem("工具栏层级")]
private static void ShowWindow()
{
    GetWindow(typeof(TestWindow), true, "测试窗口");
}

——标签Label

private void OnGUI()
{
    GUI.skin.label.fontSize = 20;
    GUI.skin.label.fontStyle = FontStyle.Bold;
    GUI.skin.label.alignment = TextAnchor.MiddleCenter;
    GUILayout.Label("测试窗口");
    GUILayout.Label(Resources.Load<Texture>("Resources文件夹下的图片路径")); 
}

Project目录下右键—Create—GUI Skin可以看到所有可修改的属性

——文本字段TextField

string txt;

private void OnGUI()
{
    txt = EditorGUILayout.TextField("输入文本：", txt);
}

——密码字段PasswordField

string txt;

private void OnGUI()
{
    txt = EditorGUILayout.PasswordField("密码：", txt);
    
}

——整数字段IntField、浮点数字段FloatField

int value_int;
float value_float;

private void OnGUI()
{
    value_int = EditorGUILayout.IntField("输入整数：", value_int);
    value_float = EditorGUILayout.FloatField("输入浮点数：", value_float);
}

——二维向量字段Vector2Field、三维向量字段Vector3Field

private Vector3 v3;
private Vector3 v2;

private void OnGUI()
{
    v3 = EditorGUILayout.Vector3Field("三维向量", v3);
    v2 = EditorGUILayout.Vector2Field("二维向量", v2);
}

——物体字段ObjectField

GameObject go;
Camera camera;

private void OnGUI()
{
    go = (GameObject)EditorGUILayout.ObjectField("赋值物体", go, typeof(GameObject),     true);    
    camera = (Camera)EditorGUILayout.ObjectField("赋值相机", camera, typeof(Camera), true);
}

——颜色字段ColorField

private Color color;

private void OnGUI()
{
    color = EditorGUILayout.ColorField("颜色", color);
}

——标签字段TagField

private string tag;

private void OnGUI()
{
    tag = EditorGUILayout.TagField("tag", tag);
}

——层级字段LayerField

private int layer;

private void OnGUI()
{
    layer = EditorGUILayout.LayerField("layer", layer);
}

——按钮Button

private void OnGUI()
{    
    if (GUILayout.Button("按钮", GUILayout.Width(50), GUILayout.Height(50)))
     {
         //按下按钮后执行的方法
     }
}

——多行文本TextArea

string txt;

private void OnGUI()
{
    GUILayout.BeginHorizontal();
    GUILayout.Label("输入文本：",GUILayout.MaxWidth(50));
    txt = EditorGUILayout.TextArea(txt, GUILayout.MaxHeight(50));
    GUILayout.EndHorizontal();
}

——单选框Toggle

bool b;

private void OnGUI()
{
    b = EditorGUILayout.Toggle("单选框", b);
}

——开关组

GameObject go;
string txt;
bool b;

private void OnGUI()
{
    b = EditorGUILayout.BeginToggleGroup("开启区域", b);
    txt = EditorGUILayout.TextField("输入文本：", txt);
    go = (GameObject)EditorGUILayout.ObjectField("赋值物体", go, typeof(GameObject), true);
    EditorGUILayout.EndToggleGroup();
}

——可选择文本SelectableLabel(用于需要复制的文本)

private void OnGUI()
{
    EditorGUILayout.SelectableLabel("微信号：597094538");
}

——滑动条Slider、整数滑动条IntSlider

int value_int;
float value_float;

private void OnGUI()
{
    value_float = EditorGUILayout.Slider("滑动条", value_float, 1, 10);
    value_int = EditorGUILayout.IntSlider("滑动条", value_int, 1, 10);
}

——字符串类型的弹出选择菜单Popup

private int index = 0;
string[] values = { "value1", "value2", "value3" };

private void OnGUI()
{
    index = EditorGUILayout.Popup("选择", index, values);
}

——枚举类型的弹出选择菜单Popup

public enum Value
{
    Value1,
    Value2,
    Value3,
}
private Value value;


private void OnGUI()
{
    value = (Value)EditorGUILayout.EnumPopup("选择", value);
}

——工具栏Toolbar

string[] values = { "Menu1", "Menu2", "Menu3" };
private int index = 0;
//string[] values = { "value1", "value2", "value3" };

private void OnGUI()
{
    index = GUILayout.Toolbar(index, values);
    if (index == 0)
    {
        EditorGUILayout.LabelField("this is menu1");
    }
    else if (index == 1)
    {
        EditorGUILayout.LabelField("this is menu2");
    }
}

——显示提示信息

private void OnGUI()
{
    if (GUILayout.Button("显示提示信息"))
    {
        ShowNotification(new GUIContent("this is a Notification"));
    }
    if (GUILayout.Button("关闭提示信息"))
    {
        RemoveNotification();
    }
}

——显示帮助信息HelpBox

private void OnGUI()
{
    EditorGUILayout.HelpBox("帮助信息", MessageType.None);
    EditorGUILayout.HelpBox("警告提示", MessageType.Warning);
}

——打开本地文件夹

private string path;

private void OnGUI()
{
    EditorGUILayout.TextField(path);
    if (GUILayout.Button("存储路径"))
    {
        path = EditorUtility.SaveFolderPanel("Path to Save", path, Application.dataPath);
    }
}

---

三：绘制一个自定义的Debug窗口

using UnityEditor;
using UnityEngine;
using UnityEngine.SceneManagement;
using System.IO;

public class DebugWindow : EditorWindow
{
    [MenuItem("Tools/Show DebugWindow")]
    private static void ShowWindow()
    {
        GetWindow(typeof(DebugWindow), true, "Debug窗口", true);
    }

    int toolbarIndex;
    string[] toolbarStr = { "Error反馈窗口", "Warning反馈窗口" };

    bool haveError;
    bool haveErrorDes;
    string errorName;
    GameObject errorGo;
    string errorDes;
    string[] errorType = { "普通", "一般", "严重" };
    private int errorTypeIndex;
    string errorPath;

    private void OnGUI()
    {
        toolbarIndex = GUILayout.Toolbar(toolbarIndex, toolbarStr);
        if (toolbarIndex == 0)
        {
            //标题标签
            GUI.skin.label.fontSize = 20;
            GUI.skin.label.fontStyle = FontStyle.Bold;
            GUI.skin.label.alignment = TextAnchor.MiddleCenter;
            GUILayout.Label("Error反馈窗口");

            haveError = EditorGUILayout.Toggle("是否有Error", haveError);
            if (haveError)
            {
                //问题名
                errorName = EditorGUILayout.TextField("问题名", errorName);
                if (errorName != null)
                {
                    if (errorName.Length == 0 || errorName == "")
                    {
                        EditorGUILayout.HelpBox("问题名不能为空", MessageType.Error);
                    }
                    else if (errorName.Length >= 5)
                    {
                        EditorGUILayout.HelpBox("问题名过长", MessageType.Warning);
                    }
                    else
                    {
                        EditorGUILayout.HelpBox("问题名合法", MessageType.Info);
                    }
                }

                //出现问题的时间
                EditorGUILayout.LabelField("当前时间", System.DateTime.Now.ToString());

                //出现问题的场景
                EditorGUILayout.LabelField("当前场景", SceneManager.GetActiveScene().name);

                //出现问题的物体
                errorGo = (GameObject)EditorGUILayout.ObjectField("问题物体", errorGo, typeof(GameObject), true);

                //问题描述
                haveErrorDes = EditorGUILayout.BeginToggleGroup("是否添加问题描述", haveErrorDes);
                EditorGUILayout.BeginHorizontal();
                EditorGUILayout.LabelField("问题描述：", GUILayout.MaxWidth(50));
                EditorGUILayout.TextArea(errorDes, GUILayout.MaxHeight(50));
                EditorGUILayout.EndHorizontal();
                EditorGUILayout.EndToggleGroup();

                //问题类型
                errorTypeIndex = EditorGUILayout.Popup("问题类型", errorTypeIndex, errorType);

                //问题保存路径
                EditorGUILayout.BeginHorizontal();
                if (GUILayout.Button("选择路径"))
                {
                    errorPath = EditorUtility.SaveFolderPanel("Path to Save", errorPath, Application.dataPath);
                }
                EditorGUILayout.TextField(errorPath);
                EditorGUILayout.EndHorizontal();

                GUILayout.Space(50);

                //保存到本地
                if (GUILayout.Button("保存"))
                {
                    if (errorPath == null)
                    {
                        ShowNotification(new GUIContent("请先选择保存路径"), 1);
                    }
                    else
                    {
                        Directory.CreateDirectory(errorPath + "/BugReports");
                        StreamWriter sw = new StreamWriter(errorPath + "/BugReports/" + errorName + ".txt");
                        sw.WriteLine("Error or Warning：" + toolbarStr[toolbarIndex]);
                        sw.WriteLine("问题名：" + errorName);
                        sw.WriteLine("出现问题的时间：" + System.DateTime.Now.ToString());
                        sw.WriteLine("出现问题的场景：" + SceneManager.GetActiveScene().name);
                        sw.WriteLine("问题描述：" + errorDes);
                        sw.WriteLine("问题类型：" + errorType);
                        sw.WriteLine("问题存储路径：" + errorPath);
                        sw.Close();
                    }
                }
            }
        }
        else if (toolbarIndex == 1)
        {
            GUI.skin.label.fontSize = 20;
            GUI.skin.label.fontStyle = FontStyle.Bold;
            GUI.skin.label.alignment = TextAnchor.MiddleCenter;
            GUILayout.Label("Warning反馈窗口");

            //其他的与Error反馈窗口基本相同
        }
    }
}
