Hello. I’m trying to figure out a way to subscribe to any changes in the clock’s current time made by the user via the timeline. I do not want to follow the onTick event since I have shouldAnimate and canAnimate set to false. But if the user clicks in the timeline and changes the current time I would like to respond to that event.
Since the currentTime of the clock is observable my attempt is:
Cesium.knockout.getObservable(widget.clock, ‘currentTime’).subscribe((curr_time) => {
console.info(curr_time);
});
``
However, when I try this in the console I get:
Uncaught TypeError: Cannot read property ‘subscribe’ of null
``
I’m very new to both javascript and Cesium and I would appreciate any input. Thank you for your time.
