In the URL, you need to use tokens ({x}, {y}, {zoom}) instead of values.
When requesting a tile, tokens will be replaced with values.

What is a tile system and how it works:

It's hard to say why your method doesn't show up.
Most likely this is some simple problem, for example:
- You have not added a component to GameObject.
- You added the wrong script. For example, based on the example, you created a new script with your changes, but added the original example to GameObject.
- You didn't save the script.

1. Toggle traffic on or off;
2. Change the map style from satelite to street map.

For these I am using the "CreateCustomStylesExample"script.

This script is to specifically change the map style.  I have copied and pasted my MapBox access token and also put in the zoom level and x, y (hopefully maps to lat and long coordinates but it doesn't look right to me so that might be one error). Also in the code below I had to take out the full url to post here so I know that (link) is incorrect.

 public string style1 = "(link)://a.tiles.mapbox.com/v4/mapbox.satellite/14/21.3069/-157.8583.png?access_token=obscured";
        public string style2 = "https://a.tiles.mapbox.com/v4/mapbox.streets/14/21.3069/-157.8583.png?access_token=obscured";
        public string mapboxAccessToken;

I also added in the following statement in the code which I was hoping would turn traffic on:

       public void OnClickThing()
        {
            OnlineMaps.instance.traffic = true;
        }

I click and drag the script to the On Click () "object" window for the button and the public functions do not appear.

I have also tried dragging that script onto On Click () and then put "style1" or "style2" in the MonoScript.name field.  I do not think that is right though.  Nothing happens when the buttons are pressed. 

Any pointers would be very welcome!
