如何讓一個物件跟蹤并移向另一個物件

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

public class EnemyControler : MonoBehaviour
{
    private Transform player;
    // Start is called before the first frame update
    void Start()
    {

        //Note in this case we're saving the transform in a variable to work with later. 

        //We could save the player's game object (and just remove .transform from the below) but this is cleaner
       var player = GameObject.FindWithTag("Player").transform;
    }

    // Update is called once per frame
    void Update()
    {

        //**** The code below you need to modify and move into your own method and call that method from here.

        //**** Don't overthink it. Look at how Start() is defined. Your own Move method would look the exact same.

        //**** Experiment making it private void instead of public void. It should work the same.

        //How much will we move by after 1 second? .5 meter
        var step = .5f * Time.deltaTime; // 5 m/s

        var newPosition = Vector3.MoveTowards(transform.position, player, step);//This is one way to move a game object by updating the transform. Watch the videos in this module and it should become apparent what goes here.
    }
}

轉換不會映射到標記的玩家。我試圖讓一個敵人團結起來向一個移動的玩家移動一個班級，但我完全迷失了。

您的代碼中有三個問題。首先是您player在 Start 方法中定義了一個新變數。這隱藏了player您之前定義的成員欄位。

第二個問題是您獲得了一個要移動的值，但您沒有將該值分配給當前物件位置。

第三個問題是你在Transform方法中輸入了a MoveTowards，而你本應該輸入 a Vector2。

下面的代碼應該可以糾正這些問題。

public class EnemyControler : MonoBehaviour
{
    private Transform _player;

    void Start()
    {
       _player = GameObject.FindWithTag("Player").transform;
    }

    void Update()
    {
        var step = .5f * Time.deltaTime;
        transform.position = Vector3.MoveTowards(transform.position, _player.position, step);
    }
}

嘗試做類似的事情，一旦您了解代碼，將其更改為您想要的，我過去曾使用過類似的事情

        public int minRange;
        private Transform target = null;
        
            private void OnTriggerEnter(Collider other)
            {
                if (other.tag == "Player")
                    target = other.transform;
            }
        
            private void OnTriggerExit(Collider other)
            {
                if (other.tag == "Player")
                    target = null;
            }   
        
            void update()
            {
                transform.LookAt(target);
                float distance = Vector3.Distance(transform.position, 
                target.position);
                bool tooClose = distance < minRange;
                Vector3 direction = tooClose ? Vector3.back : Vector3.forward;
                if (direction == Vector3.forward)
                {
                    transform.Translate(direction * 6 * Time.deltaTime);
                }
                else
                {
                    transform.Translate(direction * 3 * Time.deltaTime);
                 }
            }
