Perhaps the problem is that you are using OnlineMapsControlBase.OnMapZoom.
This will only be triggered when the user interacts with the map (wheel, double click, pitch to zoom, etc.).
This will not be triggered when the zoom is changed using inspector.
For OnZoom to be triggered with any zoom change, use OnlineMaps.OnChangeZoom.
In the project, I'm using OnlineMaps.OnChangeZoom. After plugin update, my variant of scale markers doesn't work correctly at all in the editor, but on android work's fine with float zoom(but with int step zoom - not, I mean if you zoom by double tap).
Changed version of your script is attached.
As you can see, I'm using a different way to scale markers.
Sorry, but I don't see the attached file.
Anyway, thanks for helping!

P.S. Online Maps has been updated.
]]>2. DrawMarker. I do not know what you wanted to achieve, but your way of scaling the markers seems to me very strange. With 99% probability this way is wrong.
If you could suggest the better way I would be very grateful. Thanks!
]]>In addition, I found a couple of problems in your code:
1. In OnZoom, NullReference exception is possible, because you do not check that markerInstance is not null.
2. DrawMarker. I do not know what you wanted to achieve, but your way of scaling the markers seems to me very strange. With 99% probability this way is wrong.
This is a bug in OnlineMapsControlBase.GetPosition.
Fixed. The new version will be available soon.
Most likely you do not need this, but in Online Maps v3 there is an opportunity to rewrite marker drawer without creating your own system of markers.
You use the built-in marker engine + your own marker drawer.
Example:
using UnityEngine;
public class uGUIMarkerDrawer:MonoBehaviour
{
private static uGUIMarkerDrawer instance;
public RectTransform container;
public GameObject prefab;
private Canvas canvas;
private Camera worldCamera
{
get
{
if (canvas.renderMode == RenderMode.ScreenSpaceOverlay) return null;
return canvas.worldCamera;
}
}
private void OnEnable()
{
instance = this;
canvas = container.GetComponentInParent<Canvas>();
}
private void Start()
{
OnlineMapsControlBase.instance.markerDrawer = new Drawer(OnlineMapsControlBase.instance);
}
public class Drawer : OnlineMapsMarker2DDrawer
{
private OnlineMapsControlBase control;
public Drawer(OnlineMapsControlBase control)
{
this.control = control;
control.OnDrawMarkers += OnDrawMarkers;
}
public override void Dispose()
{
control.OnDrawMarkers -= OnDrawMarkers;
control = null;
}
private void OnDrawMarkers()
{
double tlx, tly, brx, bry;
map.GetCorners(out tlx, out tly, out brx, out bry);
foreach (OnlineMapsMarker marker in OnlineMapsMarkerManager.instance.items)
{
DrawMarker(marker, tlx, tly, brx, bry);
}
}
private void DrawMarker(OnlineMapsMarker marker, double tlx, double tly, double brx, double bry)
{
double px, py;
marker.GetPosition(out px, out py);
GameObject markerInstance = marker["instance"] as GameObject;
if (px < tlx || px > brx || py < bry || py > tly)
{
if (markerInstance != null)
{
OnlineMapsUtils.Destroy(markerInstance);
marker["instance"] = null;
}
return;
}
if (markerInstance == null)
{
marker["instance"] = markerInstance = Instantiate(instance.prefab);
(markerInstance.transform as RectTransform).SetParent(instance.container);
markerInstance.transform.localScale = Vector3.one;
}
Vector2 screenPosition = control.GetScreenPosition(px, py);
RectTransform markerRectTransform = markerInstance.transform as RectTransform;
screenPosition.y += markerRectTransform.rect.height / 2;
Vector2 point;
RectTransformUtility.ScreenPointToLocalPointInRectangle(markerRectTransform.parent as RectTransform, screenPosition, instance.worldCamera, out point);
markerRectTransform.localPosition = point;
}
}
}
