如何使子弹射向游戏对象

Question

我目前正在研究TurretAi。 我这样做是为了当敌人在一定范围内时，炮塔会瞄准敌人，但我无法让炮塔向敌人射击弹丸。 这是目前我所拥有的这是炮塔类。

using UnityEngine;
using System.Collections;

public class Defence : MonoBehaviour {

    public float DistanceFromCastle,CoolDown;
    public GameObject enemy;
    public GameObject Bullet;
    public int protectionRadius,bulletSpeed;

    // Use this for initialization
    void Start () 
    {
        protectionRadius = 35;
        bulletSpeed = 50;
        CoolDown = 5;

    }

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

        enemy = GameObject.FindGameObjectWithTag("Enemy");

        if(enemy != null)
        {
            DistanceFromCastle = Vector3.Distance(GameObject.FindGameObjectWithTag("Enemy").transform.position,GameObject.FindGameObjectWithTag("Defence").transform.position);
            //print (DistanceFromCastle);
            if(DistanceFromCastle <= protectionRadius)
            {
                attackEnemy();
            }

        }
    }
    void attackEnemy()
    {
        transform.LookAt(enemy.transform);
        CoolDown -= Time.deltaTime;
        if (CoolDown <= 0)
        {

            Debug.DrawLine(transform.position,enemy.transform.position,Color.red);
            Instantiate(Bullet,Vector3.forward,Quaternion.identity);

            print("attack Enemy");
            CoolDown = 5;
        }
    }
}

我也已经有一个冷静的变种，所以它每5秒只拍摄一次，任何帮助都会很棒。

您已经很接近了，您需要更改以下行：

Instantiate(Bullet, Vector3.forward, Quaternion.identity);

对此：

private const int SPAWN_DISTANCE = 5;

Instantiate(Bullet, transform.position + SPAWN_DISTANCE * transform.forward, transform.rotation);

Quaternion.identity是指：

该四元数对应于“不旋转”。
