WRLD Sdk Objects not following path

Unity Engine
1

Our team is using WRLD sdk for our current project. We are trying to have some objects follow a predefined path of geographic coordinates (basically points from google maps). The problem is that the object do not properly follow the path. We have defined the following path:

new List<LatLong>
                {
                    LatLong.FromDegrees(53.748667, -0.248243),
                    LatLong.FromDegrees(53.748828, -0.249892),
                    LatLong.FromDegrees(53.748813, -0.250043),
                    LatLong.FromDegrees(53.748644, -0.250342),
                    LatLong.FromDegrees(53.748560, -0.250416),
                    LatLong.FromDegrees(53.746968, -0.250809)
                };

When the objects move from one point to another, it does not follow a straight line and does not closely match the road in WRLD.

This is the code we use to make an object follow the path:

public IEnumerator MoveThroughWaypoints(List<LatLong> path)
    {
        if (path == null || path.Count == 0)
        {
            yield return null;
        }
        else
        {
            Position = path[0];
            VehicleGeographicTransform.SetPosition(Position);
            for (int i = 1; i < path.Count; i++)
            {
                LatLong target = path[i];
                while (LatLong.EstimateGreatCircleDistance(Position, target) > 1)
                {
                   
                    Vector2 positionVector2 = MakeVector2FromLatLong(Position);
                    Vector2 targetVector2 = MakeVector2FromLatLong(target);
                   
                    positionVector2 = Vector2.MoveTowards(positionVector2, targetVector2, Time.deltaTime / 3000);

                    LatLong result = LatLong.FromDegrees(positionVector2.x, positionVector2.y);
                    Position = result;

                    VehicleGeographicTransform.SetPosition(Position);

                    yield return null;
                }
            }
        }

We welcome any suggestions to try to solve this issue.
Thanks :slight_smile:

Replace your “move along” code to something that puts marker objects (perhaps little magenta-colored spheres) in along the lines that the object is supposed to use.

Once that runs, press PAUSE to stop the editor, then investigate the coordinates of those objects, see where the math might be going wrong.
