拍摄延迟（Unity 和 C#）

Question

我在Unity里做拍摄，我想做的是做一点延时，比如：能每0.5秒拍一次。检查脚本，我希望我的子弹预制件在 0.5 秒延迟后出现（实例化）。

private Rigidbody2D rb2d;
private float h = 0.0f;
public float Speed;
public Transform firePoint;
public GameObject bulletPrefab;


    // Start is called before the first frame update
void Start()
{
    rb2d = GetComponent<Rigidbody2D>();

}

// Update is called once per frame
void Update()
{
    h = Input.GetAxisRaw("Horizontal");
    if (h != 0.0f)
    {
        rb2d.velocity = new Vector2(h * Speed, rb2d.velocity.y);
    }
    if (h == 0.0f)
    {
        rb2d.velocity = new Vector2(0, rb2d.velocity.y);

    }

    if (Input.GetKeyDown(KeyCode.Space))
    {
        Shoot();
    }
}


void Shoot()
{
    Instantiate(bulletPrefab, firePoint.position, firePoint.rotation);
}

这应该会带您走向正确的方向，当然，这只是其中一种方法。

你可以改变fireDelay来改变射速。

private Rigidbody2D rb2d;
private float h = 0.0f;
public float Speed;
public Transform firePoint;
public GameObject bulletPrefab;

float fireElapsedTime = 0;
public float fireDelay = 0.2f;


    // Start is called before the first frame update
void Start()
{
    rb2d = GetComponent<Rigidbody2D>();

}

// Update is called once per frame
void Update()
{
    h = Input.GetAxisRaw("Horizontal");
    if (h != 0.0f)
    {
        rb2d.velocity = new Vector2(h * Speed, rb2d.velocity.y);
    }
    if (h == 0.0f)
    {
        rb2d.velocity = new Vector2(0, rb2d.velocity.y);

    }

    fireElapsedTime += Time.deltaTime;

    if (Input.GetKeyDown(KeyCode.Space) && fireElapsedTime >= fireDelay)
    {
        fireElapsedTime = 0;
        Shoot();
    }
}


void Shoot()
{
    Instantiate(bulletPrefab, firePoint.position, firePoint.rotation);
}
