如何遞回獲取每個專案的級別？

public class GetChildsEditorWindow : EditorWindow
{
    public Transform transform;
    int levelsMin = 3, levelsMax = 4;
    static int currentLevel;
    List<Transform> allChildren = new List<Transform>();
    static int oldLevel = 0;
    Vector2 scrollPos;

    // Add menu named "My Window" to the Window menu

        // Get existing open window or if none, make a new one:
        GetChildsEditorWindow window = (GetChildsEditorWindow)EditorWindow.GetWindow(typeof(GetChildsEditorWindow), false, "Get Childs");
        window.Show();
    }

    private void OnGUI()
    {
        GUILayout.Space(20);
        transform = EditorGUILayout.ObjectField("Transform to get childs", transform, typeof(Transform), true) as Transform;

        EditorGUI.BeginDisabledGroup(transform == null);
        currentLevel = (int)EditorGUILayout.Slider("Slider", currentLevel, levelsMin, levelsMax);
        EditorGUI.EndDisabledGroup();

        if (allChildren != null && allChildren.Count > 0)
        {
            EditorGUILayout.BeginHorizontal();
            scrollPos =
                EditorGUILayout.BeginScrollView(scrollPos, GUILayout.Width(400), GUILayout.Height(400));
            for (int i = 0; i < allChildren.Count; i  )
            {
                allChildren[i] = EditorGUILayout.ObjectField("Transform "   i.ToString(), allChildren[i], typeof(Transform), true) as Transform;
            }
            EditorGUILayout.EndScrollView();
            EditorGUILayout.EndHorizontal();
        }

        if (oldLevel != currentLevel)
        {
            if (transform != null)
            {
                allChildren = new List<Transform>();
                IterateOverChild(transform, currentLevel, levelsMax);
                oldLevel = currentLevel;
            }
        }

        if(GUILayout.Button("GEt it"))
        {
            IterateOverChild(transform, 1);
            Debug.Log(currentLevel);
        }
    }

    public void IterateOverChild(Transform original, int currentLevel, int maxLevel)
    {
        if (currentLevel > maxLevel) return;
        for (var i = 0; i < original.childCount; i  )
        {
            Debug.Log($"{original.GetChild(i)}");
            allChildren.Add(original.GetChild(i));
            IterateOverChild(original.GetChild(i), currentLevel   1, maxLevel);
        }
    }

    public void IterateOverChild(Transform original, int currentLevel)
    {
        for (var i = 0; i < original.childCount; i  )
        {
            Debug.Log($"{original.GetChild(i)}");
            allChildren.Add(original.GetChild(i));
            IterateOverChild(original.GetChild(i), currentLevel   1);            
        }
    }
}

我想自動獲得每個物件的所有級別深度并將其顯示在編輯器視窗中。

例如 ：

Object 1 is at level 0
Onject 2 is at level 3
Object 3 is at level 0

但我遇到了一些問題：

現在的代碼第二個方法 IterateOverChild 最終顯示 3 個級別，但有 4 個級別。以及如何顯示每個物件的級別？

在螢屏截圖中，紅色箭頭是 1 級，綠色箭頭是 2 級黃色 3 級和藍色 4 級：

我在 1 級看到兩個 GameObject 游戲物件和 GameObject (1)，然后在 2 級看到 2 個 GameObject，在 3 級看到兩個物件，最后一個在 4 級。這就是我看到關卡邏輯的方式。

我想用物件和每個物件在每個物件附近的哪個級別更新 ui 編輯器視窗面板以顯示級別編號。（我給物件命名為 Level 1 Level 2 Level 3 Level 4 只是為了用我如何看待關卡的邏輯來命名它們）。

uj5u.com熱心網友回復：

如何獲得任何變換的級別？

這種方法完全顯示了水平。只需將所需的轉換放入引數中：

public static int ObjectLevel(Transform current, int level = 0)
{
    if (current.parent) return ObjectLevel(current.parent,   level);

    return level;
}

一行中的類似方法：

public static int ObjectLevel(Transform current, int level = 0) => current.parent ? ObjectLevel(current.parent,   level) : level;

一個例子...

這里顯示了所有游戲物件的級別：

public void Start()
{
    foreach (var _transform in GameObject.FindObjectsOfType<Transform>())
    {
        var level = ObjectLevel(_transform);
        
        _transform.name  = ", level: "   level;
    }
}

結果：
