大家好，又见面了，我是你们的朋友全栈君。

笔者以往在使用一些插件的时候经常会看上面这种多炫酷的插件操作界面，常常羡慕不已，如今有了Odin，自己也可以简简单单的实现这些炫酷的效果了，下面笔者就带大家初识OdinWindow。

创建一个Window

不积跬步无以至千里，我们先从最简单的创建一个Window开始,只需要自定义一类并继承OdinEditorWindow即可

public class MySimpleEditorWindow : OdinEditorWindow
{
    [MenuItem("My Game/My Simple Editor")]
    private static void OpenWindow()
    {
        GetWindow<MySimpleEditorWindow>().Show();
    }

    public string Hello = "菜鸟海澜";
}

混合Window

完成第一步后，我们可以根据笔者Odin主页中的特性来填充这个Window了

public class MyHybridEditorWindowOne : OdinEditorWindow
{
    [MenuItem("My Game/My Hybrid Editor")]
    private static void OpenWindow()
    {
        GetWindow<MyHybridEditorWindowOne>().Show();
    }

    [EnumToggleButtons, BoxGroup("Settings")]
    public ScaleMode ScaleMode;

    [FolderPath(RequireExistingPath = true), BoxGroup("Settings")]
    public string OutputPath;

    
    [HorizontalGroup(0.5f)]//占比0.5
    public List<Texture> InputTextures;

    [HorizontalGroup, InlineEditor(InlineEditorModes.LargePreview)]
    public Texture Preview;

    [Button(ButtonSizes.Gigantic), GUIColor(0, 1, 0)]
    public void PerformSomeAction()
    {

    }
}

using Sirenix.OdinInspector;
using Sirenix.OdinInspector.Editor;
using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEngine;


/*
 * 通过从OdinEditorWindow而不是EditorWindow继承，您可以使Unity编辑器窗口的方式与创建检查器的方式完全相同：仅使用属性。

提示：您可以使用 OnInspectorGUI 属性，如果您希望将自定义编辑器IMGUI代码与Odin绘制的编辑器混合使用
 */
public class SomeWindow : OdinEditorWindow
{
    [MenuItem("My Game/My Window")]
    private static void OpenWindow()
    {
        GetWindow<SomeWindow>().Show();
    }

    [PropertyOrder(-10)]
    [HorizontalGroup]
    [Button(ButtonSizes.Large)]
    public void SomeButton1() { }

    [HorizontalGroup]
    [Button(ButtonSizes.Large)]
    public void SomeButton2() { }

    [HorizontalGroup]
    [Button(ButtonSizes.Large)]
    public void SomeButton3() { }

    [HorizontalGroup]
    [Button(ButtonSizes.Large), GUIColor(0, 1, 0)]
    public void SomeButton4() { }

    [HorizontalGroup]
    [Button(ButtonSizes.Large), GUIColor(1, 0.5f, 0)]
    public void SomeButton5() { }

    [TableList]
    public List<SomeType> SomeTableData;
}

public class SomeType
{
    [TableColumnWidth(50)]
    public bool Toggle;

    [AssetsOnly]
    public GameObject SomePrefab;

    public string Message;

    [TableColumnWidth(160)]
    [HorizontalGroup("Actions")]
    public void Test1() { }

    [HorizontalGroup("Actions")]
    public void Test2() { }
}

使用OdinMenuEditorWindow保持井井有条

这个就厉害了，一个Window集成数个功能，让每个功能以菜单的形式进行选择并显示。
这里需要注意的是，这次并不是继承OdinEditorWindow，而是继承OdinMenuEditorWindow，并使用OdinMenuTree中的Add和AddAllAssetsAtPath函数添加菜单

Add： 设置菜单名称并传入对应需要渲染的类
AddAllAssetsAtPath：设置菜单名称，传入路径，示例中的第一个bool是指是否包含子路径，第二bool表示是否子路径的所有可用类都在一个层级中渲染。选择false就是下面这种形式

using Sirenix.OdinInspector;
using Sirenix.OdinInspector.Editor;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UnityEditor;
using UnityEngine;

public class MyMenuEditorWindow : OdinMenuEditorWindow
{
    [MenuItem("My Game/My Menu Editor")]
    private static void OpenWindow()
    {
        GetWindow<MyMenuEditorWindow>().Show();
    }

    protected override OdinMenuTree BuildMenuTree()
    {
        var tree = new OdinMenuTree();
        tree.Selection.SupportsMultiSelect = false;

        tree.Add("Settings", GeneralDrawerConfig.Instance);
        tree.Add("Utilities", new TextureUtilityEditor());
        tree.AddAllAssetsAtPath("Odin Settings", "Assets/Plugins/Sirenix", typeof(ScriptableObject), true, true);
        return tree;
    }
}

public class TextureUtilityEditor
{
    [BoxGroup("Tool"), HideLabel, EnumToggleButtons]
    public Tool Tool;

    public List<Texture> Textures;

    [Button(ButtonSizes.Large), HideIf("Tool", Tool.Rotate)]
    public void SomeAction() { }

    [Button(ButtonSizes.Large), ShowIf("Tool", Tool.Rotate)]
    public void SomeOtherAction() { }
}

功能强大且可自定义的OdinMenuTrees

public class MyTreeEditorWindow : OdinMenuEditorWindow
{
    [MenuItem("My Game/My Tree Editor")]
    private static void OpenWindow()
    {
        GetWindow<MyTreeEditorWindow>().Show();
    }

    protected override OdinMenuTree BuildMenuTree()
    {
        var tree = new OdinMenuTree();
        tree.DefaultMenuStyle = OdinMenuStyle.TreeViewStyle;

        tree.Add("Menu Style", tree.DefaultMenuStyle);

        var allAssets = AssetDatabase.GetAllAssetPaths()
            .Where(x => x.StartsWith("Assets/"))
            .OrderBy(x => x);

        foreach (var path in allAssets)
        {
            tree.AddAssetAtPath(path.Substring("Assets/".Length), path);
        }

        tree.EnumerateTree().AddThumbnailIcons();

        return tree;
    }
}

在编辑器窗口中渲染实例对象

您可以覆盖GetTarget方法，并给它任何类型的实例来呈现。

public class MyTargetEditorWindow : OdinEditorWindow
{
    [MenuItem("My Game/My Target Editor")]
    private static void OpenWindow()
    {
        GetWindow<MyTargetEditorWindow>().Show();
    }

    protected override void Initialize()
    {
        this.WindowPadding = Vector4.zero;
    }

    protected override object GetTarget()
    {
        return Selection.activeObject;
    }
}
