Parallax Help

This is what I have now

And this is the code I'm working with to try and achieve it

    [SerializeField] bool scrollLeft;

    float singleTextureWidth;

    void Start()
    {
        SetupTexture();
    }

    void SetupTexture()
    {
        Sprite sprite = GetComponent<SpriteRenderer>().sprite;
        singleTextureWidth = sprite.texture.width / sprite.pixelsPerUnit;
    }

    void Scroll()
    {
        float delta = moveSpeed * Time.deltaTime;
        transform.position += new Vector3(delta, 0f, 0f);
    }

    void CheckReset()
    {
        if ((Mathf.Abs(transform.position.x) - singleTextureWidth) > 0)
        {
            transform.position = new Vector3(0.0f, transform.position.y, transform.position.z);
        }
    }

    void Update()
    {
        Scroll();
        CheckReset();
    }

Granted, I still need to figure out how to implement it as a group instead of relying on the size of a singular sprite
