为什么在创建新的 GameObjects 时它不更改标签？

Question

在第一个脚本中：

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

public class InstantiateObjects : MonoBehaviour
{
    public GameObject prefab;
    public Terrain terrain;
    public float yOffset = 0.5f;

    private float terrainWidth;
    private float terrainLength;

    private float xTerrainPos;
    private float zTerrainPos;


    void Start()
    {
        //Get terrain size
        terrainWidth = terrain.terrainData.size.x;
        terrainLength = terrain.terrainData.size.z;

        //Get terrain position
        xTerrainPos = terrain.transform.position.x;
        zTerrainPos = terrain.transform.position.z;

        //generateObjectOnTerrain();
    }

    public void generateObjectOnTerrain(bool parent, string tag)
    {
        //Generate random x,z,y position on the terrain
        float randX = UnityEngine.Random.Range(xTerrainPos, xTerrainPos + terrainWidth);
        float randZ = UnityEngine.Random.Range(zTerrainPos, zTerrainPos + terrainLength);
        float yVal = Terrain.activeTerrain.SampleHeight(new Vector3(randX, 0, randZ));

        //Apply Offset if needed
        yVal = yVal + yOffset;

        //Generate the Prefab on the generated position        
        GameObject objInstance = Instantiate(prefab, new Vector3(randX, yVal, randZ), Quaternion.identity);
        if (parent)
            objInstance.transform.parent = this.transform;
        objInstance.transform.tag = tag;
    }
}

在我使用的脚本中：

private void Start()
    {
        for (int i = 0; i < cloneTeleportations; i++)
        {
            InstantiateObjects gos = GetComponent<InstantiateObjects>();
            gos.prefab = prefab;
            gos.generateObjectOnTerrain(true, "ddd");//"Teleportation");
        }
    }

如果我将其从 true 更改为 false，它将不会生成 GameObjects 子项，如果是 true，它们将是子项。父部分正在工作。但是为了测试，我尝试将标签更改为 "ddd"，我在第一个脚本中看到标签是 "ddd":

objInstance.transform.tag = tag;

标签是 "ddd" 并且 objInstance.transform.tag 默认是 "Teleportation" 当运行游戏中所有克隆的游戏对象都被标记为 "Teleportation" 而不是 "ddd".

在 Unity 中，您必须先从编辑器中手动添加 tag，然后才能将其分配给 GameObject。如果 tag 不存在，则无法分配它。

为什么在创建新的 GameObjects 时它不更改标签？

Why when creating new GameObjects it's not changing the tag?
