爲什麼在創建新的GameObjects時不會更改標籤？

Question

在第一個腳本：

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; 
    } 
} 

而在腳本，我使用這個：

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

如果我將它從真更改爲false它不會使孩子的GameObjects，如果這是真的，他們會成爲孩子。母公司正在運作。 但對於測試我試圖改變標籤爲「DDD」我在第一個腳本看到，標籤是「DDD」：

objInstance.transform.tag = tag; 

標籤爲「DDD」和objInstance.transform.tag默認情況下爲當運行遊戲時，所有被標記爲「Teleportation」而非「ddd」的克隆遊戲對象都是「傳送」。

Unity您必須首先在編輯器中手動添加tag，然後才能將其分配給GameObject。如果tag不存在，則不能分配它。
