Thanks this was helpful on getting things working again on iOS too. Did take me a little while to figure out that "click Assets/Input Settings" meant on the main menu select "Assets/Create/Input Actions"

LocalJoost commented 1 year ago

@timothyt I am sorry about the confusion. First of all, it should have said "right-click" in stead of click. And the "Assets" prefix should not have been there. Fixed. Thanks for the feedback.

I am happy you got things working on iOS. Please write a blog post of how you went about ;) I don't have a Mac, so I can't try it myself.

Hi Joost!

Thanks for this article, very interesting! Some time ago I was thinking about the feasibility of using a diegetic UI with smartphones (vs only with eyewear XR), and it looks like this project would be a great jumping-off point for such an experiment.

I'm running into an issue though, hope you have an idea about a fix. When I open the project (using Unity 2021.3.10f1 on Windows, so a bit newer than the Unity version used for the repo) I get this error about the RealityCollective service framework package not being resolved.

RealityCollective framework resolution error

So, assuming that perhaps the package has moved, I went to the RealityCollective website and saw this URL for importing the package: https://github.com/realitycollective/com.realitycollective.service-framework.git

When I add the package in Package Manager using that Git URL a good set of versions becomes available. But the version used in the project (1.0.0.preview-7) isn't there.

RealityCollective framework version missing in Package Manager

So I choose the next higher version that works, which is 1.0.1, and that gets loaded, yay!

Except that a single error now remains: Assets\MRTKExtensions\Services\MRTK3ConfigurationFindingServiceProfile.cs(10,79): error CS0246: The type or namespace name 'IServiceDataProvider' could not be found (are you missing a using directive or an assembly reference?)

One hypothesis is that the IServiceDataProvider is actually an interface from Unity and this is caused by that version difference, but that seems like a long shot considering that in Visual Studio this using statement at the top of MRTK3ConfigurationFindingServiceProfile.cs is greyed-out: using RealityCollective.ServiceFramework.Interfaces;

I'm not familiar enough (or rather: at all..) with the Service Framework to troubleshoot this. Do you have an idea for what could be a solution?

LocalJoost commented 11 months ago

I know exactly what the problem is. Unity f*cked up the package chain, which makes the pre release version unavailable. And Just before release, the ServiceFramework authors changed a bit of the API for some reason. I warned them this would break all the samples out in the wild) including mine).

I can't fix this particular problem right now. If you have the patience to wait a bit, I will. If you don't have that patience, have a look at https://localjoost.github.io/HoloLens-AI-using-Yolo-ONNX-models-to-localize-objects-in-3D-space/ that features a service as well, but one implemented after they broke stuff

Ah, that's good to know, and thanks for the link!

I'm not in a huge hurry, won't have time to continue with this until August 1st.

LocalJoost commented 11 months ago

So I am back and finally have some time. I have an MRTK3 version, upgraded to the latest of everything, on Unity 2021.3.23f1 here for you https://github.com/LocalJoost/QRCodeService/tree/MRTK3

ptc-lexvandersluijs commented 10 months ago

Sounds good, thanks Joost!

I'm running into one thing though, and that's that when I switch to Android as the Build Target, I get this error:

BuildFailedException: No valid MRTK Profile for build target platform. Check Project Settings/Mixed Reality Toolkit and apply a valid MRTKProfile to your target platform. Microsoft.MixedReality.Toolkit.Editor.MRTKBuildProcessor.UnityEditor.Build.IPreprocessBuildWithReport.OnPreprocessBuild (UnityEditor.Build.Reporting.BuildReport report) (at Library/PackageCache/com.microsoft.mrtk.core@66c690c1a686/Editor/MRTKBuildProcessor.cs:66) UnityEditor.Build.BuildPipelineInterfaces+<>c__DisplayClass16_0.b__1 (UnityEditor.Build.IPreprocessBuildWithReport bpp) (at <964670f15c6b47f9b8f9340732720473>:0) UnityEditor.Build.BuildPipelineInterfaces.InvokeCallbackInterfacesPair[T1,T2] (System.Collections.Generic.List1[T] oneInterfaces, System.Action1[T] invocationOne, System.Collections.Generic.List1[T] twoInterfaces, System.Action1[T] invocationTwo, System.Boolean exitOnFailure) (at <964670f15c6b47f9b8f9340732720473>:0) UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&)

Seems like I need to do a deep dive into the magical world of MRTK to understand how to solve this. Is this obvious for you, or am I asking for too much?
