进行跑道轮换时，跑道无法出现

Question

按照教程走，但是同样的代码，我的跑道无法出现

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

public class ObjectPool : MonoSingleton<ObjectPool>
{
    //资源目录
    public string ResourceDir="" ;

    Dictionary<string, SubPool> m_pools = new Dictionary<string, SubPool>();

    //取物体
    public GameObject Spawn(string name,Transform trans)
    {
        SubPool pool = null;
        if(!m_pools.ContainsKey(name))
        {
            RegieterNew(name,trans);
        }
        pool = m_pools[name];
        return pool.Spawn();
    }

    //回收物体
    public void Unspawn(GameObject go)
    {
        SubPool pool = null;
        foreach(var p in m_pools.Values)
        {
            if (p.Contain(go))
            {
                pool = p;
                break;
            }
        }
        pool.UnSpawn(go);
    }

    //回收所有
    public void UnspawnAll()
    {
        foreach(var p in m_pools.Values)
        {
            p.UnspawnAll();
        }
    }

    //新建一个池子
    void RegieterNew(string names,Transform trans)
    {
        //生成目录
        string path = ResourceDir + "/" + names;
        //生成预制体
        GameObject go = Resources.Load<GameObject>(path);
        //新建池子
        SubPool pool = new SubPool(trans,go);
        m_pools.Add(pool.Name, pool);
    }
}

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

public class RoadChange : MonoBehaviour 
{
	GameObject roadNow;
	GameObject roadNext;
	GameObject parent;

	private void Start () 
	{
		if(parent==null)
        {
			parent = new GameObject();
			parent.transform.position = Vector3.zero;
			parent.name = "Road";
		}

		roadNow = Game.Instrance.objectPool.Spawn("Pattern_1", parent.transform);
		roadNext = Game.Instrance.objectPool.Spawn("Pattern_2", parent.transform);
		roadNext.transform.position += new Vector3(0, 0, 160);
	}
	
	private void OnTriggerEnter(Collider other)
    {
		if (other.gameObject.tag == Tag.road)
        {
			//回收
			Game.Instrance.objectPool.Unspawn(other.gameObject);

			//创建新的跑道
			SpawnNewRoad();
        }
    }

	void SpawnNewRoad()
    {
		int i = Random.Range(1, 5);

		//生成新的游戏对象
		roadNow = roadNext;
		roadNext = Game.Instrance.objectPool.Spawn("Pattern_"+i.ToString(), parent.transform);
		roadNext.transform.position = roadNow.transform .position+ new Vector3(0,0,160);
    }
}

在Unity中已经选中了路径，但是无法出现
