为什么我不能将我的播放器附加到脚本中的转换？

Question

I am trying to make a script where the zombie looks for the player and if the player enters the boundaries it will start chasing it. My problem is that I can't attach my player to the script in the inspector and I am unsure why. I don't have a problem with the code(at least I don't think so) only with it not attaching. The player is a prefab from the unity Standard assets.

Edit: The script is attached to a prefab in my assets. The player in in the hierarchy.

Just in case here is my code

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

public class ZK_attack : MonoBehaviour
{    
    public Transform Player;
    public float MoveSpeed = 4.5f;
    public float MaxDist = 4.0f;
    public float MinDist = 1.5f;
    private Coroutine animat = null;
    private Animator anim;


    void Update()
    {
        

        transform.LookAt(Player);

        if (Vector3.Distance(transform.position, Player.position) >= MinDist)
        {
            transform.position += transform.forward * MoveSpeed * Time.deltaTime;
            anim.SetBool("inRadius", true);

            if (Vector3.Distance(transform.position, Player.position) <= MaxDist)
            {
                anim.SetBool("AttackingPlayer", true);


            }

        }

        if (Vector3.Distance(transform.position, Player.position) <= MinDist)
        {
            anim.SetBool("inRadius", false);
        }

        if (Vector3.Distance(transform.position, Player.position) >= MaxDist)
        {
            anim.SetBool("AttackingPlayer", false);
        }
    }
}

Ok, the problem was that you can only drag objects into scripts that are in your scene already, unless they are prefabs themselves in the assests folder, even though it is on an object. To accomplish what you need, in your Start() add

Player = GameObject.Find("...name of object you wish to set as Player").transform;
