Thanks a lot, that did the trick. When using the debugger, I saw that the ExtraField property was null. Probably put a breakpoint too soon, so I didn't look into the ExtraField. Thanks again !

Hi.

Unfortunately, you didn't specify which version of Online Maps you are using.
Here is an example for Online Maps v4. It can be easily ported for v3.

using System.Linq;
using OnlineMaps;
using UnityEngine;

public class DynamicToken : MonoBehaviour
{
    public Map map;
    public string mapboxAccessToken;

    public string[] mapTypes = {
        "osm.mapnik",
        "mapbox.satellite",
    };
    
    private void OnGUI()
    {
        for (int i = 0; i < mapTypes.Length; i++)
        {
            string mapType = mapTypes[i];
            if (GUILayout.Button(mapType))
            {
                SetMapType(mapType);
            }
        }
    }
    
    private void Start()
    {
        if (!map) map = GetComponent();
        if (string.IsNullOrEmpty(mapboxAccessToken))
        {
            Debug.LogError("Mapbox Access Token is required.");
            return;
        }

        SetMapType(mapTypes[0]);
    }

    private void SetMapType(string mapType)
    {
        map.mapType = mapType;
        if (!mapType.StartsWith("mapbox.")) return;
        
        TileProvider.ExtraField tokenField = TileSources.mapbox.extraFields.FirstOrDefault(f =>
        {
            TileProvider.ExtraField ef = f as TileProvider.ExtraField;
            return ef != null && ef.title == "Access Token";
        }) as TileProvider.ExtraField;

        if (tokenField != null) tokenField.value = mapboxAccessToken;
    }
}

Setting access token when changing mapType dynamically

Hi ! I just got this asset yesterday, and it's pretty great.

However, I've got a problem with the access token for MapBox.

What I'm doing is changing map.mapType between osm.mapnik and mapbox.satellite with the press of a UI button. The change works, but the problem is that I can't seem to be able to set the access token for mapbox this way. The field doesn't stay serialized and I can't find a property of method to set it from the code when switching to it.

How could I achieve this behaviour ?

Thanks in advance
