flattens the hierarchy by assigning all child objects directly to an parent in the Unity Editor. 모든 자식을 하나의 부모로 평탄화 하는 스크립트

 

using System.Collections.Generic;

using UnityEngine;

using UnityEditor;

public class HierarchyFlattor: EditorWindow

{

    private Transform _parent;

    [MenuItem("Tools/HierarchyFlattor")]

    public static void ShowWindow()

    {

        GetWindow<HierarchyFlattor>("HierarchyFlattor");

    }

    private void OnGUI()

    {

        GUILayout.Label("Set all childs parent to selected parent", EditorStyles.boldLabel);

        _parent = EditorGUILayout.ObjectField("Parent Object", _parent, typeof(Transform), true) as Transform;

        if(GUILayout.Button("Flatten"))

        {

            if(_parent != null)

            {

                Execute(_parent);

            }

        }

    }

    public void Execute(Transform parent)

    {

        List<Transform> allChild = new();

        AddAllChild(allChild, _parent);

        FlattenAllSub(allChild, parent);

    }

    private void AddAllChild(List<Transform> container, Transform parant)

    {

        for (int i = 0; i < parant.childCount; i++)

        {

            Transform CurChild = parant.GetChild(i).transform;

            container.Add(CurChild);

            AddAllChild(container, CurChild);

        }

    }

    private void FlattenAllSub(List<Transform> container, Transform parent)

    {

        foreach (Transform child in container)

        {

            Debug.Log($"Flatten{child.name}");

            Undo.SetTransformParent(child, parent, "Flatten All Sub");

        }

    }

}

Asset에 Editor 폴더 생성후 스크립트를 그 안에 넣은후 Tool에서 HierarchyFlattor 실행하면 됩니다.
