TimeIntervalCollectionProperty: Detect change / event?

CesiumJS
1

I have a TimeIntervalCollectionProperty. I am trying to detect when the value changes, i.e., at the start / end of an Interval, and change the colour of an entity. Is there any way to do this with event handler, etc., or am I going to have to setup a new TimeIntervalCollectioProperty to track the change points?

Thanks,

Hugh

Hi Hugh,

I don’t think there is an event that is raised when the property changes according to the TimeIntervalCollection, but you could use a CallbackProperty that gets the current position and maps that to the proper color.

Thanks,
