Unreal Engine 4 is available for Win10 UWP app dev now

[Jerry.Richards]

[MENTION=494622]jsyarrow[/MENTION] - Well, I took different strategy and was able to open the EraAdapter project just by double-clicking on it. I modified the HintPath in the project file but still encountered the same error.

Basically, I used VS2017 Open -> File -> Open With, selected XML (Text) Editor, replaced HintPath with:
MICROSOFT_UWP_UNREAL\Engine\Plugins\Online\XboxOne\OnlineSubsystemLive\ThirdParty\XSAPI\UWP\build\native\lib\x64\v140\Release\Microsoft.Xbox.Services.winmd

[Jerry.Richards]

No improvement after performing the above steps.

[EDIT]
According to the link https://docs.microsoft.com/en-us/uwp...ive-extensions
we should have the following contracts:

Windows.Gaming.XboxLive.StorageApiContract, version=1.0.
Windows.Networking.XboxLive.XboxLiveSecureSocketsContract, version=1.0

Unfortunately, I don't see either of them. How can I tell if my XboxLive is working or not? I can access the services from within UE4 but my separate project is having a problem. Is it a compiler switch?

[jsyarrow]

That reference should be part of the Xbox Live Extensions SDK which you will have installed thanks to the GetXboxLiveSDK script. Try removing both the broken Windows.Networking.XboxLive.XboxLiveSecureSocketsContract and the Xbox Live Extension SDK references, and then readding the latter (Add reference -> Extensions).

[Jerry.Richards]

[MENTION=494622]jsyarrow[/MENTION] - I have a VS2017 solution setup for EraAdapter, and I can compile cleanly all the sources files, except one, Networking.cpp.

Networking is referencing Windows::Networking::XboxLive namespace but I can't resolve it. I tried adding the reference

Windows.Networking.XboxLive.XboxLiveSecureSocketsContract

but that didn't help, and the reference shows a caution icon next to it. Thinking that it was a compatibility issue, I tried adding it to a project with a wider range of support:

Build 15063
Build 10240

which showed the same caution icon after adding the reference. I was trying different from - to target combinations but VS2017 returned an HRESULT when trying to create the solution.

For the EraAdapter project (15063 to 10586) the following references are present:

Windows.ApplicationModel.Calls.CallsVoipContract
Windows.Devices.Printers.PrintersContract
Windows.Foundation.FoundationContract
Windows.Foundation.UniversalApiContract
Windows.Graphics.Printing3D.Printing3DContract
Windows.Networking.Connectivity.WwanContract
Microsoft.Xbox.Services (from XSAPI path)
Windows.Networking.XboxLive.XboxLiveSecureSocketsContract (warning icon)
Xbox Live Extension SDK

The other Contract references were added automatically after reopening the solution.

Do you have any suggestions?

[Jerry.Richards]

Okay, thank you. I'll look at it more tomorrow. Trying to convert it to VS2017 first since that's what I have installed. If that fails, I reinstall VS2015 and try again.

[jsyarrow]

Right, I wouldn't try to add it to the UE4 sln, just build it independently and copy the binaries. I found it wouldn't open in VS2017 for some reason, but VS2015 was able to open the vcxproj. Anyway, as you fix up the MSBuild xml you'll want to deal with the HintPath in the reference to Microsoft.Xbox.Services - it's using an old path structure to locate XSAPI and will need edits to find your new Live SDK version.

[Jerry.Richards]

(EraAdapter) may need a rebuild to pick up changes in the new Live SDK version you're using. The vcxproj is part of the fork in the OnlineSubsystemLive/ThirdParty/EraAdapter/Source folder, but it will need some tweaking to account for that XSAPI path change you ran into earlier.

I wasn't able to add the EraAdapter project file to the UEUWP solution. Also, when I tried to double-click on it Visual Studio couldn't determine the type it is. Now I'm looking at the Xml Settings of the project to see if I can recreate a new solution for it, then add the source files for it.

If you get a building version, you should drop the output .dll and .winmd in the OnlineSubsystemLive/ThirdParty/EraAdapter/Binaries/UWPxx folders.

If I understand you correctly, copy the files from a successful build to the directory listed above.

[jsyarrow]

That line is emitted at 'Log' level, which might be filtered out before it reaches the file. 0x80070057 is a credible code though - it is of course 'invalid parameter'.

One thought on where this might be coming from - the EraAdapter library has some dependencies on the public interface exposed by XSAPI. It may need a rebuild to pick up changes in the new Live SDK version you're using. The vcxproj is part of the fork in the OnlineSubsystemLive/ThirdParty/EraAdapter/Source folder, but it will need some tweaking to account for that XSAPI path change you ran into earlier. If you get a building version, you should drop the output .dll and .winmd in the OnlineSubsystemLive/ThirdParty/EraAdapter/Binaries/UWPxx folders.

[Jerry.Richards]

That was funny, I was using disassembly and I came up with 0x80070057, which I don't know is correct or not:





But I did found the logs, a lot easier I might add, and the below shows what was available:

[2017.06.14-23.47.04:183][  0]LogOnline:Warning: LIVE: No SecureDeviceAssociationTemplateName specified in the engine ini file.
[2017.06.14-23.47.04:183][  0]LogOnline:Warning: LIVE: FOnlineAchievementsLive: Failed to find json OSS achievements config: ../../../LongshotHero/Config/OSS/Live/Achievements.json
[2017.06.14-23.47.04:677][  0]LogOnline:Warning: LIVE: FOnlineSessionLive::GetSessionSettings: couldn't find session 'Game'

"Error in SystemUI" was not found. I'm still searching.

[jsyarrow]

If you're running with latest and using cookonthefly, the logs get written through the cook server connection and land in (the slightly odd) Saved/Cooked/UWP64/[Game]/UWPLocalAppData folder. With pre-cooked content they get written to the standard UWP local appdata directory: %localappdata%/Packages/[Package_Family_Name]/LocalState

Given your symptoms, the core sign in seems to be going through (and so getting cached, preventing UI from showing up subsequently), but the follow-up operation that retrieves the user's Xbox Live profile is failing. Some of this code lives in OnlineSubsystemLive/ThirdParty/EraAdapter/Source/SystemUI.cpp and OnlineSubsystemLive/ThirdParty/EraAdapter/User.cpp.

[Jerry.Richards]

[MENTION=494622]jsyarrow[/MENTION] - the returned value for the asynchronous call is 3, which is an error:




Given this, the PickedUser is never set. Where is the log written to? It wasn't in AppData\Local, and I didn't see it under Binaries, and Saved\Logs don't seem to have the SystemUI error in it.

[Jerry.Richards]

To log out you can use the Windows 10 Xbox app. After logging out there and then relaunching your game it should trigger the UI again.

That is a nice one

As for exceptions, note that there are some internal retry paths where the Xbox Live SDK code may throw an exception, catch it itself, and ultimately return a successful result from an API.

Okay, that is useful information.

Though if you're getting a null user id it sounds as though this isn't one of those cases.

I'll try to track this down, without this working, I can't use the services.


Btw, the packaging worked too.

[jsyarrow]

Hurrah!

That summary looks right to me. I will make sure to apply those changes next time I have a chance to get the fork updated. Thanks again for working through them with me, and your patience!

To log out you can use the Windows 10 Xbox app. After logging out there and then relaunching your game it should trigger the UI again. There is also a method in the core Xbox Live SDK that supports changing user in-game, but there's no wrapper for it in OnlineSubsystemLive currently.

[MENTION=494622]jsyarrow[/MENTION] - After logging in, an exception was thrown in UWP code. I'm not exactly sure where, as I continued my application wanting to see if my callback was called. It was, but PlayerId was null.

Unfortunately I'm not able to login again, the call to ShowLoginUI is ignored, even after stopping and restarting the debugger, the UI is not displayed.

Do I need to Logout first?
Is there a way to always show the UI so that players can change to a different gamertag?

[EDIT]
Even after a complete reboot the UI doesn't show. Is it that since I'm already logged in the Xbox Live services already know the account info?

Unfortunately PlayerId is still null

[Jerry.Richards]

[MENTION=494622]jsyarrow[/MENTION] - success:




What have I learned from this exercise:

1. Microsoft Server is way, way, way out :D
2. We need the latest $xsapiVersionUwp = "2017.05.20170517.001"
3. A change to Install-LivePackage is needed:
	$nativeReleasePackage = $installLocation + "\" + $packageName + ".Native.Release." + $packageVersion
	if (Test-Path $nativeReleasePackage)
	{
		$actualPath = $nativeReleasePackage
	}
	else
	{
		$actualPath = $installLocation + "\" + $packageName + "." + $packageVersion
	}
4. OnlineSubsystemLive.build.cs needs to be changed:
	const string CppRestVersion = "2_9";

Did I miss anything for this part of it?
