物体移动

• 使用 rigidbody.velocity 移动
• 使用 rigidbody.angularVelocity 旋转

private Rigidbody rigidbody;
    // Start is called before the first frame update
    void Start()
    {
        rigidbody = this.GetComponent<Rigidbody>();
    }


    private void FixedUpdate()
    {
        float v = Input.GetAxis("Vertical");
        float h = Input.GetAxis("Horizontal");

        rigidbody.velocity = transform.forward * v  * speed;
        rigidbody.angularVelocity = transform.up * h   * angularSpeed;
    }
