Query a feature layer

Query objects from a feature layer and show them on the map.

How to use the sample

1. Open the FeatureLayer_lvl level.
2. Click on the ArcGISMapActor in the Outliner panel.
3. Set your API key under Authentication section in the Details panel.
4. Click play and select a stadium from the list.

How it works

1. Create a new C++ class and make a http request to query a feature layer.
2. Create a new Blueprint Actor class
   • Create the event to place the stadium data returned from the feature layer.
   • Create a function to spawn the actor according to the stadium NAME.
   • Create a function to apply different materials according to the LEAGUE value.
   • Attach the ArcGIS Location Component to the static stadium mesh model.
   • Create a function to place the static mesh model on the geometry's coordinates location returned by the feature layer query and the height calculated by raycasts.
3. Create a widget for the viewport so users can select a stadium 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.
