敌人射弹脚本不会射击最近的物体

Question

我一直在试图弄清楚 Enemy 如何不返回多个 GameObjects 它只返回一个。我不确定它是否是我的 Bullet 脚本，它只允许返回一个对象。我目前正在尝试与 Slither.io 等多个玩家一起开发游戏，所以我不确定性能是否受到影响我想使用（列表功能）但不知道从哪里开始，我正在使用更高版本统一 2017.3.1f1。非常感谢您的帮助。脚本如下。

public class RandomAIProjectile
{
    private GameObject[] target;
    
    public float speed;
    
    Rigidbody2D bulletRB;
    
    public GameObject explosionEffect;
    
    // Find Targets Section.
    void Start () 
    {
        if (target == null)
            target = GameObject.FindGameObjectsWithTag("Player");
        
        for (int i = 0; i < target.Length; i++) 
        {
            bulletRB = GetComponent<Rigidbody2D> ();
            
            Vector2 moveDir = (target[i].transform.position - transform.position).normalized * speed;
            
            bulletRB.velocity = new Vector2 (moveDir.x, moveDir.y);
            
            Destroy (this.gameObject, 2);
        }
        
    }
    
    private void OnTriggerEnter2D(Collider2D other)
    {
        // Decoy Script To Destroy Players.
        if (other.gameObject.GetComponent<BlackthronpodDiePlayer>() != null)
        {
            Destroy (other.gameObject);
            Destroy (gameObject); 
        }
        // Damage Effect.
        if (other.gameObject.tag == "Player") {
            Instantiate (explosionEffect, transform.position, Quaternion.identity);
            Destroy(gameObject);
        }
        // Player (Bullet) Destroy Enemy.
        if (other.CompareTag ("Bullet"))
        {
            Destroy (other.gameObject);
            Destroy (gameObject); 
        }
        
        
    }
}

这是播放器脚本

public class RandomAIEnemy

    //Random Movement
    
    public float speed;
    
    public float waitTime;
    
    public float startWaitTime;

    public float lineOfSite;
    
    public float shootingRange;
    
    public float fireRate = 1f;
    
    private float nextFireTime;
    
    public GameObject bullet;
    
    public GameObject bulletParent;

    // My Current Player

    // Player AI
    private GameObject[] player;

    public GameObject blood;
    
    Vector3 respawn = new Vector3 (-34f,0,0);
    
    //Additional Info
    
    
    void FixedUpdate () 
    {

    // Use this for initialization
    void Start () 
    {
        //My Player AI Tag.
        player = GameObject.FindGameObjectsWithTag("Player");
        
        waitTime = startWaitTime;

        //My Current Player Tag.
        playerX = GameObject.FindGameObjectWithTag ("Player").GetComponent<BlackthronpodPlayerX>();

        //Random Movement Reference

    }


     //Closest (My Player Including Player AI.)
    private bool TryGetClosestPlayer(out GameObject closest)
    {

        return closest;
    }

确保您已将 Rigidbody2d 附加到您的敌人和玩家身上。另外，代码中是否有任何错误？
