    Hi,
    I am trying to follow along the tutorials here,
    https://developer.microsoft.com/en-...deo_learnmore_yt_USA_holomark_Organic_0229_11

    I have installed the required unity files, and the visual studio files. Only thing i could not install was the hololens emulator because it stops during installation for some reason. I am trying to follow the tutorial anyway determined to follow along until the build step.

    I downloaded the asset files provided in the tutorial page, opened them up in Unity Version 5.4.0b10-HTP Personal and get the following 3 errors in the unity console,

    Assets/Holograms/Support/Spatial Mapping/SpatialMapping.cs(44,18): error CS1061: Type `UnityEngine.VR.WSA.SurfaceObserver' does not contain a definition for `OnSurfaceChanged' and no extension method `OnSurfaceChanged' of type `UnityEngine.VR.WSA.SurfaceObserver' could be found (are you missing a using directive or an assembly reference?)

    Assets/Holograms/Support/Spatial Mapping/SpatialMapping.cs(54,22): error CS1501: No overload for method `Update' takes `0' arguments

    Assets/Holograms/Support/Spatial Mapping/SpatialMapping.cs(116,33): error CS0120: An object reference is required to access non-static member `UnityEngine.VR.WSA.SurfaceObserver.RequestMeshAsync(UnityEngine.VR.WSA.SurfaceData, UnityEngine.VR.WSA.SurfaceObserver.SurfaceDataReadyDelegate)'

    Are these errors occuring due to the missing emulator installation? If not, then how can i resolve these issues?

    Hello,

    These are errors in the script of that project, based on the errors you have in your script it looks like it is out of date with current API.

    For issues with the emulator I would recommended looking on Microsoft forums or contacting them for support.

    https://developer.microsoft.com/en-US/windows/holographic/using_the_hololens_emulator

    You can look up the API which contains examples in the editor.
    Click Help->Scripting reference UnityEngine.VR.WSA and look for Surface Observer in the Classes drop down

    Thank you,
    Wesley

    Thank you for the prompt response.
    I will try and re download the asset files to see if they have changed them to match the new api.

    Issue solved, the errors are not there anymore, anybody having similar issues should update their code from here https://github.com/Microsoft/HolographicAcademy/

    They updated the problem files just now, :v, i guess the instructors are listening to this thread.

    hi,
    Reference the emulator install error, I found it errored when Hyper V was not installed (requires Windows Pro licence).
