我有一个函数，它在某个位置查找"瓷砖"，将其添加到列表中，然后将该列表返回到另一个列表。但是，当游戏运行时，检查器中不会显示任何列表项，即使当我使用调试或DebugiderLog时，它也会显示列表包含正确的"瓷砖"。
下面是我的代码：

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

public class PieceController : MonoBehaviour
{
    [Header("Location managing")]
    public Tile currentTile;
    public Vector3 currentTilePos;

    [Header("Move making")]
    public Piece pieceType;
    public List<Tile> validTiles = new List<Tile>();

    private TileSelector tileSelector;

    // Start is called before the first frame update
    void Start()
    {
        tileSelector = GameObject.Find("GameController").GetComponent<TileSelector>();

    }

    // Update is called once per frame
    void Update()
    {
        currentTilePos = currentTile.GetComponent<Tile>().positionTop;
        validTiles = CalculateValidTiles();

        Debug.Log("Valid tiles: " + validTiles.ToString());
    }

    public List<Tile> CalculateValidTiles()
    {
        float tileLength = pieceType.tileLength;
        List<Tile> tiles = new List<Tile>();

        foreach (LegalMove move in pieceType.moves)
        {
            //Debug.Log("Calculating move: " + move.name);

            Vector3 legalPosition;
            Vector3 originPosition = transform.position;

            legalPosition = new Vector3(originPosition.x + move.tilesPositiveX, originPosition.y, originPosition.z + move.tilesPositiveZ);

            //Debug.Log("Legal position: " + legalPosition.ToString());

            Ray ray = new Ray(legalPosition, Vector3.down);
            RaycastHit hit;

            if (Physics.Raycast(ray, out hit, 1.5f))
            {
                Debug.Log("Hit: " + hit.collider.gameObject.name);

                if (hit.collider.gameObject.tag == "piece" && !validTiles.Contains(hit.collider.gameObject.GetComponent<Tile>()))
                {
                    tiles.Add(hit.collider.gameObject.GetComponent<Tile>());

                    //Debug.Log("Added tile: " + hit.collider.gameObject.GetComponent<Tile>().tile);
                }
            }
        }

        Debug.Log("Tiles calculated: " + tiles.ToString());

        return tiles;
    }

}

我想不通为什么它不会显示检查器中的项目，我试过将我的编辑器版本更新到2021.3.14f1，并直接将项目添加到"validTiles"列表中，而不是使用return。
