Create ArcGIS Map with C# in Unity

WH1981

Hello,

I want to make a ArcGIS map in Unity with C++. Because with this instead of the Map Creator i can change the visibility of layers in the play modus i read. I follow the tutorial : https://developers.arcgis.com/unity/maps/tutorials/display-a-map-api/#prepare-the-script

And this i my code now:

using Esri.ArcGISMapsSDK.Components;
using Esri.ArcGISMapsSDK.Samples.Components;
using Esri.ArcGISMapsSDK.Utils.GeoCoord;
using Esri.GameEngine.Extent;
using Esri.GameEngine.Geometry;
using Esri.Unity;
using UnityEngine;
using System;

public string APIKey = "";

private ArcGISMapComponent arcGISMapComponent;
private ArcGISPoint geographicCoordinates = new ArcGISPoint(-74.054921, 40.691242, 3000, ArcGISSpatialReference.WGS84());

private void CreateArcGISMapComponent()
{
	arcGISMapComponent = FindObjectOfType<ArcGISMapComponent>();

	if (!arcGISMapComponent)
	{
		var arcGISMapGameObject = new GameObject("ArcGISMap");
		arcGISMapComponent = arcGISMapGameObject.AddComponent<ArcGISMapComponent>();
	}

	arcGISMapComponent.OriginPosition = geographicCoordinates;
	arcGISMapComponent.MapType = Esri.GameEngine.Map.ArcGISMapType.Local;
	arcGISMapComponent.MapTypeChanged += new ArcGISMapComponent.MapTypeChangedEventHandler(CreateArcGISMap);
}

public void CreateArcGISMap()
{
	var arcGISMap = new Esri.GameEngine.Map.ArcGISMap(arcGISMapComponent.MapType);
	arcGISMap.Basemap = Esri.GameEngine.Map.ArcGISBasemap.CreateImagery(APIKey);

	arcGISMap.Elevation = new Esri.GameEngine.Map.ArcGISMapElevation(new Esri.GameEngine.Elevation.ArcGISImageElevationSource("https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer", "Elevation", ""));

	var layer_1 = new Esri.GameEngine.Layers.ArcGISImageLayer("https://tiles.arcgis.com/tiles/nGt4QxSblgDfeJn9/arcgis/rest/services/UrbanObservatory_NYC_TransitFrequency/MapServer", "MyLayer_1", 1.0f, true, "");
	arcGISMap.Layers.Add(layer_1);

	var layer_2 = new Esri.GameEngine.Layers.ArcGISImageLayer("https://tiles.arcgis.com/tiles/nGt4QxSblgDfeJn9/arcgis/rest/services/New_York_Industrial/MapServer", "MyLayer_2", 1.0f, true, "");
	arcGISMap.Layers.Add(layer_2);

	var layer_3 = new Esri.GameEngine.Layers.ArcGISImageLayer("https://tiles.arcgis.com/tiles/4yjifSiIG17X0gW4/arcgis/rest/services/NewYorkCity_PopDensity/MapServer", "MyLayer_3", 1.0f, true, "");
	arcGISMap.Layers.Add(layer_3);

	var buildingLayer = new Esri.GameEngine.Layers.ArcGIS3DObjectSceneLayer("https://tiles.arcgis.com/tiles/P3ePLMYs2RVChkJx/arcgis/rest/services/Buildings_NewYork_17/SceneServer", "Building Layer", 1.0f, true, "");
	arcGISMap.Layers.Add(buildingLayer);

	var extentCenter = new Esri.GameEngine.Geometry.ArcGISPoint(-74.054921, 40.691242, 3000, ArcGISSpatialReference.WGS84());
	var extent = new ArcGISExtentCircle(extentCenter, 100000);

	arcGISMap.ClippingArea = extent;

	arcGISMapComponent.View.Map = arcGISMap;
}

private ArcGISCameraComponent cameraComponent;

private void CreateArcGISCamera()
{
	cameraComponent = Camera.main.gameObject.GetComponent<ArcGISCameraComponent>();

	if (!cameraComponent)
	{
		var cameraGameObject = Camera.main.gameObject;

		cameraGameObject.transform.SetParent(arcGISMapComponent.transform, false);
		cameraComponent = cameraGameObject.AddComponent<ArcGISCameraComponent>();
		cameraGameObject.AddComponent<ArcGISCameraControllerComponent>();
		cameraGameObject.AddComponent<ArcGISRebaseComponent>();
	}

	var cameraLocationComponent = cameraComponent.GetComponent<ArcGISLocationComponent>();

	if (!cameraLocationComponent)
	{
		cameraLocationComponent = cameraComponent.gameObject.AddComponent<ArcGISLocationComponent>();
		cameraLocationComponent.Position = geographicCoordinates;
		cameraLocationComponent.Rotation = new ArcGISRotation(55, 58, 0);
	}
}

private void Start()
{
	CreateArcGISMapComponent();
	CreateArcGISCamera();
	CreateSkyComponent();
	CreateArcGISMap();
}

private void CreateSkyComponent()
{
#if USE_HDRP_PACKAGE
		var currentSky = FindObjectOfType<UnityEngine.Rendering.Volume>();
		if (currentSky)
		{
			ArcGISSkyRepositionComponent skyComponent = currentSky.gameObject.GetComponent<ArcGISSkyRepositionComponent>();

			if (!skyComponent)
			{
				skyComponent = currentSky.gameObject.AddComponent<ArcGISSkyRepositionComponent>();
			}

			if (!skyComponent.arcGISMapComponent)
			{
				skyComponent.arcGISMapComponent = arcGISMapComponent;
			}

			if (!skyComponent.CameraComponent)
			{
				skyComponent.CameraComponent = cameraComponent;
			}
		}
#endif
}

And get this errors:

Who can help me a bit with this?

Best regards

Hey I ran into a similar problem to you but I was able to get around it. The way got it to work probably isn't best practice however so i am very open to feedback. First I declared the public layer at the very beginning of the map creator script:

 public Esri.GameEngine.Layers.ArcGIS3DObjectSceneLayer layer_1;

 

In the CreateArcGISMap function, I didn't declare the layer as a variable.

        layer_1 = new Esri.GameEngine.Layers.ArcGIS3DObjectSceneLayer("https://tiles.arcgis.com/tiles/hMKr5amzqrWbbTo8/arcgis/rest/services/IncomePerCap_low_elevation/SceneServer", "Income Per Capita low extrusion", 1.0f, true, "");

 

And then I wrote a function within my map creator script (not a new script like you have done) that is used to toggle the layers on and off.

 public void ToggleIncome()
    {
       
        if (layer_1_visibility == true)
        {
            Debug.Log("Remove Layer 1");
            arcGISMap.Layers.Remove(arcGISMap.Layers.IndexOf(layer_1));
            
            layer_1_visibility = false;

            Debug.Log("layer_1_visibility" + layer_1_visibility);

            return;
        }

        if (layer_1_visibility == false)
        {
            Debug.Log("add Layer 1");
            arcGISMap.Layers.Add(layer_1);
            
            layer_1_visibility = true;

            Debug.Log("layer_1_visibility" + layer_1_visibility);
            
            return;
        }

        
        
    }

This for the most part has worked fine for me to use buttons to toggle layers on and off (except when sideloading onto quest 2 which results in some glitching of layer)

Below is my full segment of the map creator script :

using Esri.ArcGISMapsSDK.Samples.Components;
