I have worked out what I was doing wrong. Boy, it is FANTASTIC. Now a 3D view of my generated city, from which I can take multiple snap images, and lead my players along 3D streets. This tool has become just fantastic.
What did you do? I dropped it directly onto the view and nothing is working.
I open my Widows explorer, minimized both windows and dragged the JSon onto the picture in City viewer, an voila. Took a few goes though.
Doesn't work for me.
I get this:
The devicemotion events are blocked by feature policy.
window.addEventListener("devicemotion",$bind(this,this.handleSensorEvent),false);
