Topic: Draw Line from GPX

Hi Alex,

Am having trouble drawing a line on a tileset map from points in a GPX file. File is parsed fine, I pass the 

OnlineMapsGPXObject.TrackSegment.points

into 

OnlineMapsDrawingLine

and I even get a 

true

returned for 

path.visible

but there remains no line drawn across the tileset? Here's the code I'm using ...

if(File.Exists(pathToGPX))
        {
            // Load data from file into string
            string data = File.ReadAllText(pathToGPX, Encoding.UTF8);

            // Attempt to load data as GPX object
            gpx = OnlineMapsGPXObject.Load(data);

            foreach(OnlineMapsGPXObject.Track route in gpx.tracks)
            {
                Debug.LogFormat("Bike Track - {0}",route.name);
                foreach(OnlineMapsGPXObject.TrackSegment segment in route.segments)
                {
                    Debug.LogFormat("Route {0}, points {1}",route.name,segment.points.ToString());

                    for(int i=0; i<segment.points.Count;i++) Debug.LogFormat("Waypoint - {0},{1}",segment.points[i].lat, segment.points[i].lon);

                    OnlineMapsDrawingLine path = new OnlineMapsDrawingLine(segment.points, Color.red);

                    api.AddDrawingElement(path);
//                    api.Redraw();

                    Debug.Log("path is visible?? "+path.visible);
                }

Am I missing something really obvious / stupid??  Help please ;-)

Re: Draw Line from GPX

Ok, so found out what was going on so thought I'd post here in case its of use to anyone else -- The points in the GPX file are stored as {lat,long} but the list of Vectors required for OnlineMapsDrawingLine need to be {long,lat} ;-)

Re: Draw Line from GPX

Hello.

segment.points - is List <OnlineMapsGPXObject.Waypoint>.
OnlineMapsDrawingLine uses IEnumerable, where elements is Vector2, float or double.

The correct way:

OnlineMaps.instance.AddDrawingElement(new OnlineMapsDrawingLine(segment.points.Select(p => new Vector2((float)p.lon, (float)p.lat)), Color.red));

or

OnlineMaps.instance.AddDrawingElement(new OnlineMapsDrawingLine(segment.points.SelectMany(p => new [] {p.lon, p.lat}), Color.red));

Re: Draw Line from GPX

Thanks Alex, sorted it now :-)

I am trying to capture user interaction (clicks initially) along the line that's being drawn and get some information back such as name of line and location along the path - is this possible? Also I can't seem to implement a tooltip for a line either, is this also possible?

Thanks

Re: Draw Line from GPX

Hello.

In the current version - no, the line has not HitTest method, and all events and tooltips will be ignored.
If you really need events for the line, we can try to implement it.
