c# - 为什么我得到 'IsFinite(outDistanceForSort)' Unity

Question

收到此错误：'IsFinite(outDistanceForSort)'，你们知道我的代码有什么问题吗？

问题是球有时会自己破坏，有时速度会降低，或者当球与其他物体碰撞时，它会以一种奇怪的动作前后移动！

这是我的代码：

    private void Start()
    {
        BallCollectEffect.Stop();
        FireWorksEffect.Stop();
        ContinueButton.SetActive(false);
        rb = GetComponent<Rigidbody>();

        count = 0;
        setcountText();
        winText.text = "";
        audioSource1 = GetComponent<AudioSource>();
        audioSource2 = GetComponent<AudioSource>();
    }

    void FixedUpdate () {

        //rb.AddForce(Vector3.forward * speed * Time.deltaTime);
        transform.position += Vector3.forward * Time.deltaTime * speed;
        //rb.AddForce(0, 0, speed *Time.deltaTime);
        //rb.velocity = transform.forward * speed;
        //rb.MovePosition(transform.position + transform.forward * speed);
    }

    void OnCollisionEnter(Collision collision)
    {
        if (collision.gameObject.CompareTag ("Enemy"))
        {
            audioSource2.Play();
            SpeedEffect.Stop();
            rb.gameObject.SetActive(false);
            Instantiate(BallDestroyEffect, transform.position, transform.rotation);
            FindObjectOfType<GameManager>().EndGame();

        }
        if (collision.gameObject.CompareTag("End"))
        {
            ContinueButton.SetActive(true);
            winText.text = "Level Completed!";
            SpeedEffect.Stop();
            FireWorksEffect.Play();
        }
        if(collision.gameObject.CompareTag("Glass"))
        {
            audioSource1.Play();
            count = count + 3;
            setcountText();
            BallCollectEffect.Play();
            if (FloatingTextPrefab)
            {
                ShowFloatingText();
            }
        }
    }

    void ShowFloatingText()
    {
        Instantiate(FloatingTextPrefab, transform.position, Quaternion.identity, transform);
    }


    void setcountText ()  {
        countText.text = count.ToString();
    }
}
