EditorWindow 编辑器窗口

• 1:介绍,unity中的场景窗口、游戏窗口、电影窗口等，所有这些都是EditorWindow。Unity编辑是集合了具有各种功能的editor窗而成的。

编写弹出窗口代码

• 1:第一种写法弹出窗口

    public class TestEditorWindow : EditorWindow
    {
        static TestEditorWindow testWindow;
  
        [MenuItem("Tools/Example")]
        static void Open()
        {
            if (testWindow == null)
            {
                testWindow = CreateInstance<TestEditorWindow>();
            }
            testWindow.Show();
        }
    }

• 2:第二种写法,GetWindow方法是上面写的一堆API的集合,并且缓存了一个 TestEditorWindow 再次获取并不会重新生成一个

    public class TestEditorWindow : EditorWindow
    {
        static TestEditorWindow testWindow;
  
        [MenuItem("Tools/Example")]
        static void Open()
        {
            GetWindow<TestEditorWindow>();
        }
    }

• 3: EditorWindow.ShowUtility 工具窗口将总是在标准窗口的前面，并在用户切换另一个应用程序时隐藏。

        if (exampleWindow == null) {
            exampleWindow = CreateInstance<Example> ();
        }
        exampleWindow.ShowUtility ();

• 4: EditorWindow.ShowPopup 没有关闭按钮,按下esc键关闭

    public class TestEditorWindow : EditorWindow
    {
        static TestEditorWindow testWindow;
  
        [MenuItem("Tools/Example")]
        static void Open()
        {
  
            if (testWindow == null)
            {
                testWindow = CreateInstance<TestEditorWindow>();
            }
            testWindow.ShowPopup();
        }
  
  

    void OnGUI()
    {
        if (Event.current.keyCode == KeyCode.Escape)
        {
            testWindow.Close();
        }
    }
}

* 5: PopupWindow,在Editor中再弹出一个窗口

public class TestPopupWindow : EditorWindow
{
    static TestPopupWindow testWindow;
    [MenuItem("Tools/Pop")]
    static void Open()
    {
        GetWindow<TestPopupWindow>();
    }

    ExamplePupupContent popupContent = new ExamplePupupContent();

    void OnGUI()
    {
        if (GUILayout.Button("PopupContent", GUILayout.Width(128)))
        {
            var activatorRect = GUILayoutUtility.GetLastRect();
            PopupWindow.Show(activatorRect, popupContent);
        }
    }
}

public class ExamplePupupContent : PopupWindowContent
{
    public override void OnGUI(Rect rect)
    {
        EditorGUILayout.LabelField("Lebel");
    }

    public override void OnOpen()
    {
        Debug.Log("打开pop窗口");
    }

    public override void OnClose()
    {
        Debug.Log("关闭pop窗口");
    }

    public override Vector2 GetWindowSize()
    {
        return new Vector2(300, 100);
    }
}

* 6:点击其他区域会关闭

public class Example : EditorWindow
{
    static Example exampleWindow;

    [MenuItem("Tools/Drop")]
    static void Open()
    {
        if (exampleWindow == null)
        {
            exampleWindow = CreateInstance<Example>();
        }

        var buttonRect = new Rect(100, 100, 300, 100);
        var windowSize = new Vector2(300, 100);
        exampleWindow.ShowAsDropDown(buttonRect, windowSize);
    }
}

* 7:ScriptableWizard简单制作

public class Example1 : ScriptableWizard
{
[MenuItem(“Tools/ScriptableWizard”)]
static void Open()
{
DisplayWizard(“Example Wizard”);
}

void OnWizardCreate()
{
    new GameObject("gameObjectName");
}
void OnWizardUpdate()
{
    Debug.Log("Update");
}
protected override bool DrawWizardGUI()
{
    EditorGUILayout.LabelField("Label");
    return true;
}
void OnWizardOtherButton()
{
    var gameObject = GameObject.Find("gameObjectName");

    if (gameObject == null)
    {
        Debug.Log("找不到");
    }
}

}

* 8:PreferenceItem是用于在Unity Preferences中添加菜单的功能。Unity Preferences是为了对Unity编辑产生影响的设定。

using UnityEditor;

public class Example
{
    [PreferenceItem("Example")]
    static void OnPreferenceGUI ()
    {

    }
}

* 9:添加菜单的IHasCustomMenu

using UnityEditor;
using UnityEngine;

public class Example : EditorWindow, IHasCustomMenu
{

    public void AddItemsToMenu (GenericMenu menu)
    {
        menu.AddItem (new GUIContent ("example"), false, () => {

        });

        menu.AddItem (new GUIContent ("example2"), true, () => {

        });
    }

    [MenuItem("Window/Example")]
    static void Open ()
    {
        GetWindow<Example> ();
    }
}

* 10:重设图标和title

using UnityEditor;
using UnityEngine;

public class Example : EditorWindow
{
    [MenuItem ("Window/Example")]
    static void SaveEditorWindow ()
    {
        var window = GetWindow<Example> ();

        var icon = AssetDatabase.LoadAssetAtPath<Texture> ("Assets/Editor/Example.png");

        window.titleContent = new GUIContent ("Hoge", icon);
    }
}

* 11:将EditorWindow中的数据保存为ScriptableObject 

using UnityEditor;
using UnityEngine;
public class Example : EditorWindow
{
    [MenuItem ("Assets/Save EditorWindow")]
    static void SaveEditorWindow ()
    {
        AssetDatabase.CreateAsset (CreateInstance<Example> (), "Assets/Example.asset");
        AssetDatabase.Refresh ();
    }

    [SerializeField]
    string text;

    [SerializeField]
    bool boolean;
}

```
