We create a kml file with gx:MultiTrack, succeed putting it into cesium and make it move.

Basically we fallow the bike ride example([https://cesiumjs.org/Cesium/Build/Apps/Sandcastle/?src=KML.html&label=DataSources](https://cesiumjs.org/Cesium/Build/Apps/Sandcastle/?src=KML.html&label=DataSources))

But after it finish the tour, it just automatically go back to the first coordinate and start all over again.

How to make it only run once?

Hi Karl,

You should be able to get the data source (KML or CZML) **[clock](https://cesiumjs.org/Cesium/Build/Documentation/KmlDataSource.html?classFilter=kml#clock)** property. You can modify its [**clockRange**](https://cesiumjs.org/Cesium/Build/Documentation/DataSourceClock.html#clockRange)value, which will determine how the clock behaves when the end of the loop is reached. Set it to **ClockRange.LOOP\_STOP**.

Thanks,

Gabby
