Find distance , direction b/w two places

correct me if i m wrong .

this is displacement b/w two points

float DisplacementKM = OnlineMapsUtils.DistanceBetweenPoints(point1 ,point2);

....
if i m right , then there should be a function to calculate distance amoung points

when set two distant points for directions , it start showing errors..

this is my code
public void findDirection()
    {

        OnlineMapsFindDirection.Find(from.text, to.text, true).OnComplete += onFindLoaction;
        //OnlineMapsFindDirection.Find();
        Debug.Log("send request");
    }

    private void onFindLoaction(string routXml)
    {
        Debug.Log("complete");

        List<OnlineMapsDirectionStep> steps = OnlineMapsDirectionStep.TryParse(routXml);

        if (steps != null)
        {
            foreach (OnlineMapsDirectionStep step in steps) Debug.Log(step.stringInstructions);

            List<Vector2> points = OnlineMapsDirectionStep.GetPoints(steps);
            OnlineMapsDrawingLine route = new OnlineMapsDrawingLine(points, Color.green);

            OnlineMaps.instance.AddDrawingElement(route);

            Vector2 center;
            int zoom;
            OnlineMapsUtils.GetCenterPointAndZoom(points.ToArray(), out center, out zoom);

            OnlineMaps.instance.zoom = zoom;
            OnlineMaps.instance.SetPosition(center.x ,center.y);

            var distance = OnlineMapsUtils.DistanceBetweenPoints(points[0], points[points.Count -1]);

            Debug.Log("Distence" + distance);
        }
        else
        {
            Debug.Log("Find direction failed");
        }
    }

You have a very difficult route, which has a lot of points, so that the drawing element has more 65,000 vertices.

We'll fix it.
I think it will take 1-2 days.
