        horizontal = joystick.Horizontal;

        if (vertical >= 0.5f)
        {
            transform.localPosition += transform.forward * speed * Time.deltaTime;
        }
        
        if (vertical <= -0.5f)
        {
            transform.localPosition += -transform.forward * speed * Time.deltaTime;
        }

        if (horizontal >= 0.5f)
        {
            transform.localPosition += transform.right * speed * Time.deltaTime;
        }

        if (horizontal <= -0.5f)
        {
