Local .slpk file is not loading into scene

NickGuzi — Mon, 19 Aug 2024 21:31:36 GMT

Hello! I recently created a project in which I added an integrated mesh layer through a URL for a scene and it worked just fine.

I recently started a new project and am attempting to use a local .slpk file I have but the layer is not loading into the scene for some reason? Is it possible to add a local .slpk layer to a scene/is it recommended? Or is it always better to use a URL?

I am positive I have the correct coordinates for my location, and I know it isn't a project issue as I tested with the integrated mesh layer URL I had used on my previous project and that loaded into this new project scene just fine.

The local .slpk file is either a 3DObject Scene Layer or a Building Scene layer. I can't remember which at the moment but I did test with both configurations on the UI and neither loaded in.

Please let me know if you have any follow up questions or need images sent over from my project.

Thanks!

- Nick

^ I forgot to add that the .slpk is housed within the Assets folder currently. I am referencing it with a direct file path not a relative file path.

Hello,

If you are going to be loading an .slpk, we do not recommend keeping it within your project. This can cause issues with the path when making a build. If you plan to package/build your project for use on multiple devices, we recommend finding your platforms "Application.persistentdatapath", placing the .slpk there, and loading it via a C# script in the Start method. Attached is the script, please modify to fit your needs.

If you wish to not use a script, please consider placing the .slpk in a location on your computer such as Downloads, Desktop, or Documents and using the path.
Please let me know if you have any other questions or issues.

Sounds good I'll try it out, thanks!

I just realized I left out one key ingredient. I am trying to build my game into a WebGL platform. How would that affect this process? Is it possible to use a local .slpk within a WebGL game? In fact is it recommended/possible to use the SDK and build into a WebGL platform in general?

Unfortunately, we do not support WebGL at this time. We apologize for the inconvenience.

Ah I see, thank you! So WebGL isn't supported in any capacity by the SDK? Or is it only not supported if trying to use a local .slpk file?

@MasonGaw so I took your advice and added my .slpk to the persistentdatapath. I then added the script to my Unity project (I changed the layer to an ArcGIS3DObjectSceneLayer within the Start() method). I added the script to my scene through an empty object below the ArcGISMap object. This is what it looks like:

However, upon clicking play the layer is still not showing up. Is there something I am missing? Or do you think there's an actual issue with my .slpk? My persistentdatapath is as follows: C:\Users\[Username]\AppData\LocalLow\DefaultCompany\Project_Name

Can you please add the ArcGISViewStateLogging Component to your arcigs map component and send a picture of the console? Try loading it through script and try loading it how you were doing before and send the console so I can better help with debugging.

@MasonGaw So a little update. The good news is that the .slpk is loading from a local path that points to my downloads folder. So there seems to be nothing wrong with the .slpk. However, I do want this project to be extensible and shareable.

Here is my console trying to load from the persistent data path:

As you can see an error on line 22 of my script is being thrown:

using System.Collections; using System.Collections.Generic; using UnityEngine; using Esri.ArcGISMapsSDK.Components; using Esri.Unity; public class LoadLayer : MonoBehaviour { [SerializeField] private ArcGISMapComponent arcGISMapComponent; private void Awake() { arcGISMapComponent = GetComponent<ArcGISMapComponent>(); } // Start is called before the first frame update void Start() { var buildingLayer = new Esri.GameEngine.Layers.ArcGIS3DObjectSceneLayer( Application.persistentDataPath + "/AlbanyBuildings.slpk", "Albany Layer", 1.0f, true, ""); arcGISMapComponent.View.Map.Layers.Add(buildingLayer); } }

For those who are concerned I just had to do some moderate tweaking to the script that Mason attached. I decided to use a tag to find the arcGISMapComponent housed within the ArcGISMap game object and it worked. I just named the tag "ArcGISMap" and assigned it to the ArcGISMap game object. Here is my updated script:

private void Awake() { GameObject arcGISMap = GameObject.FindWithTag("ArcGISMap"); if (arcGISMap != null) { arcGISMapComponent = arcGISMap.GetComponent<ArcGISMapComponent>(); if (arcGISMapComponent == null) { Debug.LogError("ArcGISMapComponent is not found on the GameObject with tag 'ArcGISMap'."); } } else { Debug.LogError("No GameObject with tag 'ArcGISMap' found."); } }

Thank you for the help Mason!
