Fix Laggy Scrolling Unity With DOTween

Code:

public bool SmoothScrolling { get; set; } = true;

    public float SmoothScrollTime { get; set; } = 0.5f;

    void Awake()

    {

       this.content = this.gameObject.transform.GetChild(0).GetComponent<RectTransform>();

       this.viewport = this.gameObject.GetComponent<RectTransform>();

    }

    public override void OnScroll(PointerEventData data)

    {

        if (!IsActive())

            return;

 

 

        if (SmoothScrolling)

        {

            Vector2 positionBefore = normalizedPosition;

            this.DOKill(complete: true);

            base.OnScroll(data);

            Vector2 positionAfter = normalizedPosition;

 

            normalizedPosition = positionBefore;

            this.DONormalizedPos(positionAfter, SmoothScrollTime);

        }

        else

        {

            base.OnScroll(data);

        }

    }
