Question

using System.Collections.Generic;
using UnityEngine;

public class enemybullet : MonoBehaviour
{
    Transform player;

    void Start()
    {
        player = GameObject.FindGameObjectWithTag("Player").transform;

        Vector3 lastpos = player.position;

        Destroy(gameObject, 4f);
    }

gets last pos of player


 void Update()
 {
    transform.position = Vector3.MoveTowards(transform.position, player.position, 10f);
 }

走向玩家

我希望它拍摄玩家的方向，并且不允许我在movetowards功能中使用lastpos

Answer 1

这里的问题是您的变量scope。

void Start()
{
    player = GameObject.FindGameObjectWithTag("Player").transform;

    Vector3 lastpos = player.position;

    Destroy(gameObject, 4f);
}

正如您在此处看到的那样，您已经在{...}（作用域）中声明了变量，这意味着该变量将仅在其创建的范围内可见（并且实际上执行一离开{...}

就被销毁

要解决此问题，您需要在整个类的范围内声明变量

public Vector3 lastpos;

void Start()
{
    player = GameObject.FindGameObjectWithTag("Player").transform;

    lastpos = player.position;

    Destroy(gameObject, 4f);
}

您现在可以在班级内（甚至班级外）的任何地方访问lastpos
