How it works (C++)

1. Create a new C++ class and make an HTTP request to query a feature layer.
2. Create a new Blueprint Actor class
   • Create the event to place the data returned from the Weather Query.
   • Create a function to spawn the weather actor according to the data received in the query.
   • Attach the ArcGIS Location Component to the weather actor blueprint class.
   • Add additional functionality to spawn/show different Niagra Particle Effects based on the current weather data returned from the Weather Query.
3. Create a widget for the viewport so users can select a city from the list fed from the feature service.

Note: You can use UE_LOG to print log messages in the Output Log window and see if you are gathering the data properly from the feature service.
