物体序列在游戏中不被创建

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

public class AppleMgr : MonoBehaviour
{
public class AppleCreator
{
private static GameObject[] s_appleListPrefab = new GameObject[2];
public static void RandomCreate(Vector3 startPos)
{
var id = Random.Range(0, 2);
if (null == s_appleListPrefab[id])
{

            s_appleListPrefab[id] = Resources.Load<GameObject>("AppleList" + id);
        }
        var appleListRoot = Object.Instantiate(s_appleListPrefab[id]);
        var appleBhv = appleListRoot.AddComponent<Apple>();

        appleBhv.SetPos(startPos);
    }
}

}

运行结果及报错内容

我的解答思路和尝试过的方法

我想要达到的结果

下面是根据你代码的测试代码，我测试没有问题。

using UnityEngine;

public class AppleMgr : MonoBehaviour
{
    public Transform[] trf;
    public class AppleCreator
    {
        private static GameObject[] s_appleListPrefab = new GameObject[2];
        public static void RandomCreate(Vector3 startPos)
        {
            var id = Random.Range(0, 2);
            if (null == s_appleListPrefab[id])
            {

                s_appleListPrefab[id] = Resources.Load<GameObject>("AppleList" + id);
            }
            var appleListRoot = Object.Instantiate(s_appleListPrefab[id]);
            //var appleBhv = appleListRoot.AddComponent<Apple>();
            appleListRoot.transform.position = startPos;
            //appleBhv.SetPos(startPos);
        }
    }
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.P))
        { int inttger = Random.Range(0, trf.Length);
            AppleCreator.RandomCreate(trf[inttger].position);
        }
    }
}
