如何制作弯曲的飞行路径？

Question

射击时如何让子弹沿弧线飞行并击中玩家。 就像这张照片一样。 我尝试使用物理学中的公式，将身体以一定角度抛向地平线，这就是结果。 但子弹飞入虚空

velocity = Mathf.Round(Vector3.Distance(lastpos, transform.position) / Time.deltaTime);
lastpos = transform.position;
Vector3 direction = PlayeCar.position - Vector3.zero;
float angle = Mathf.Atan2(direction.y, direction.x); // радианы


float x = velocity * Mathf.Cos(angle) + gravity * (time* time) / 2;
float y = velocity * Mathf.Sin(angle);

transform.position = new Vector2(x, y)

;

Answer 1

示例定向方法可以是（脚本将附加到射击的枪上，所以当代码提到变换时，指的是枪的变换）：

 public void LaunchTarget()
{
    Vector3 initialSpeed = transform.forward; //shot direction, gun's forward
    GameObject go = GameObject.Instantiate(m_bullet);//reference to bullet prefab

    //in case you need to randomize the shot speed
    initialSpeed = transform.forward * Random.Range(m_minLaunchSpeed, m_maxLaunchSpeed); 

    //set the initial position of the bullet in the gun
    go.transform.position = transform.position;
    // shoot (give speed to the bullets rigidbody)
    go.GetComponent<Rigidbody>().velocity = initialSpeed;
    //initially disabled soas to see the bullet when shot
    go.SetActive(true);
}

希望有帮助

我做到了 ！！！！ 在子弹飞行的时候，我间歇性地将它转向玩家。 过了一会儿我删除了它

   void Start()
    {
        rigidbodyBullet = GetComponent<Rigidbody2D>();
        Player = GameObject.Find("carPlayer").GetComponent<Transform>();
        _distance = Vector3.Distance(Player.position, transform.position);
        Invoke("DestroyArcBullet", 1.5f);
        limitDistance = _distance / 1.3f;
    }


    void Update()
    {
        transform.position += transform.up * Time.deltaTime * 5f;
        _distance = Vector3.Distance(Player.position, transform.position);


        if (_distance < limitDistance)
        {
            var turn = Quaternion.Lerp(transform.rotation,
                Quaternion.LookRotation(Vector3.forward, Player.position - transform.position), Time.deltaTime * 2);
            rigidbodyBullet.MoveRotation(turn.eulerAngles.z);
        }


        if (this.transform.position.y + this.transform.position.y <= -10 || this.transform.position.y + this.transform.position.y >= 10
            || this.transform.position.x + this.transform.position.x <= -10 || this.transform.position.x + this.transform.position.x >= 10)
        {
            Destroy(gameObject);
        }
    }
