        multiplier={50}
        onTick={_.throttle(handleValue, 1000)} // this thing ticks every millisecond
      />
    <Entity
          ref={ref} // here is the ref to get the value I want to set state with
          position={positionProperty}
          tracked
          selected
          model={{ uri: model, minimumPixelSize: 100, maximumScale: 100.0 }}
          availability={
            new TimeIntervalCollection([
              new TimeInterval({ start: start, stop: stop }),
            ])
          }
        />

这是 handleValue 函数。

  const handleValue = (clock) => {
//setting the state here ( I want to display the chaning …
