using UnityEngine;
using UnityEditor;
using System.Collections.Generic;

public class ExampleScript : MonoBehaviour

    // 获取场景中所有目标对象（包括不激活的对象）不包括Prefabs:

    List<GameObject> GetAllObjectsInScene()
    {
        List<GameObject> objectsInScene = new List<GameObject>();

        foreach (GameObject go in Resources.FindObjectsOfTypeAll(typeof(GameObject)) as GameObject[])
        {
            if (go.hideFlags == HideFlags.NotEditable || go.hideFlags == HideFlags.HideAndDontSave)
                continue;

            if (!EditorUtility.IsPersistent(go.transform.root.gameObject))
                continue;

            objectsInScene.Add(go);
        }
