子彈留在原地，但我希望它移動

我想撰寫一個跟蹤我的玩家并向其射擊的敵人。玩家跟隨部分作業，但當它射擊時，子彈留在原地。Bullet 有一個設定為觸發的碰撞器。玩家有標簽 - 分配給它的玩家 這是子彈的腳本：

public float speed;
  private Transform player;
  private Vector2 target;

void Start()
    {
        player = GameObject.FindGameObjectWithTag("Player").transform;
        target = new Vector2(player.position.x, player.position.y);
    }

// Update is called once per frame
void Update()
{
    //Move projectile towards
    //Ja gribam lai lode seko transform.position = Vector2.MoveTowards(transform.position, player.position, speed * Time.deltaTime);

    transform.position = Vector2.MoveTowards(transform.position, target, speed * Time.deltaTime);
    if(transform.position.x == target.x && transform.position.y == target.y){
        DestroyProjectile();
    }
}

void OnTriggerEnter2D(Collider2D other){
   if(other.CompareTag("Player")){
       DestroyProjectile();
}
}
void DestroyProjectile(){
    Destroy(gameObject);
}

}

這是敵人的腳本：

public float speed;
public float stoppingDistance;
public float retreatDistance;
private float timeBtwShots;
public float startTimeBtwShots;
public GameObject projectile;
public Transform player;

// Start is called before the first frame update
void Start()
{
    player = GameObject.FindGameObjectWithTag("Player").transform;
    timeBtwShots = startTimeBtwShots;
}

// Update is called once per frame
void Update()
{
    //Checking distance between enemies
    if(Vector2.Distance(transform.position, player.position) > stoppingDistance)
    {
        //Move enemy towards player
        transform.position = Vector2.MoveTowards(transform.position, player.position, speed * Time.deltaTime);
    //Check if the distance is smaller and make sure if enemy isnt too near to the player
    } else if(Vector2.Distance(transform.position, player.position) < stoppingDistance && Vector2.Distance(transform.position, player.position) > retreatDistance){
        //Too near enemy will stop moving
        transform.position = this.transform.position;
    //if distance is smaller than retreat Back away
    } else if(Vector2.Distance(transform.position, player.position) < retreatDistance){

        transform.position = Vector2.MoveTowards(transform.position, player.position, -speed * Time.deltaTime);
    }

    // Shootig
    if(timeBtwShots <= 0){
        Instantiate(projectile, transform.position, Quaternion.identity);
        timeBtwShots = startTimeBtwShots;
    } else {
        timeBtwShots -= Time.deltaTime;
    }
}

}

代碼本身沒有問題，所以肯定是別的東西有問題。

一種可能性是GameObject projectile可能未在統一檢查器中設定。彈丸上也應該有一個子彈組件，所以要確保它是正確的。

原因也可能是子彈速度。默認情況下，它設定為 0，如果是，則不會移動。仔細檢查檢查器中的值以確保它不是 0。

第三種可能性是可能有多個帶有玩家標簽的物件，導致 FindGameObjectWithTag 回傳錯誤的玩家物件。這不太可能，但可以通過使用不同的方法獲取玩家物件來修復，例如在敵人腳本中設定它

@GalaxyShard ，@derHugo 感謝您的回答！原來我沒有在子彈中添加彈丸腳本！我已將彈丸腳本分配給 Player 物件，而不是子彈本身。解決了
