I was trying to apply rotation and tilt to an object using the Joystick Pack. However, only one of t

Unity Engine
,
1 
public class playerController : MonoBehaviour
{
    public Joystick input;
    public float moveSpeed;
    public float turnSpeed;
    public float tilt = 0.5f;

    private Rigidbody rb;

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

    // Update is called once per frame
    void Update()
    {
        // Joystick left and right
        float horizontalMovement = input.Horizontal;

        ////////  Only one of the following 1. works. ////////  I want to do togather!!

        //  1. Global Z axis Rotation
      transform.Rotate(0, 0, horizontalMovement * turnSpeed * Time.deltaTime, Space.World);

        //  2. At that time, Local Y axis Tilting
        Vector3 movementVector = new Vector3(horizontalMovement, 0f, 0f);
        rb.velocity = movementVector * moveSpeed;
        rb.rotation = Quaternion.Euler(0.0f, rb.velocity.x * -tilt, 0.0f);
        transform.localRotation = rb.rotation;
    }

    void FixedUpdate()
    {
        if (rb != null)
        {
            // Local Y axis default Forwarding
            rb.velocity = transform.up * moveSpeed * Time.deltaTime;
        }
    }
}

I want to know why not work 2.

Thanks Regard
