EditorUtility.CollectDeepHierarchy

Parameters

Returns

Object[] 在层级上与搜索数组关联的对象数组。

Description

收集层级视图中以每个指定对象为根对象的所有对象。

This is most useful for linearizing entire GameObject hierarchies including all their components.
Note that the traversal will not include assets referenced from within the hierarchy. For example, having a MeshFilter component in the hierarchy will not cause the referenced Mesh to be included in the resulting list.

using UnityEngine;
using UnityEditor;

public class CollectHierarchyExample : MonoBehaviour
{
    void Start()
    {
        // Create two GameObjects
        GameObject  parent = new GameObject();
        GameObject  child = new GameObject();
        Object[]    roots = new Object[] { parent };

        // Name them
        parent.name = "Parent";
        child.name = "Child";

        // Make one a child of the other.
        child.transform.parent = parent.transform;

        // Collect entire hierarchy
        Object[] result = EditorUtility.CollectDeepHierarchy(roots);

        // Dump results.  Will log four objects to the console;
        // two GameObjects ("Parent" and "Child") and two Transform
        // components (one belonging to "Parent" and one belonging to
        // "Child")
        foreach (Object obj in result)
            Debug.Log(obj);
    }
}
