Unreal Engine 4 is available for Win10 UWP app dev now

[Zelex]

yup logs show it connecting and transferring stuff.

[manoelneto]

Are you sure it's connecting? AFAIK UWP apps cannot access localhost by default, you need to setup an exception for specific apps: https://msdn.microsoft.com/en-us/lib.../dn640582.aspx

[Zelex]

Ok, so PDB loading is good now (thx!)

The -filehostip method doesn't appear to be working?

I made a whole new blank project, set it up, works 100% when launching from the editor, I run the cook server, Press F5 from the debugger, game connects to the cook server and streams some stuff, then a totally black screen.

Link to project: https://www.dropbox.com/s/18mj8d6hvdrdwfz/UWP2.7z?dl=0

They're in the Binaries/UWPxx folder. If you hit Load Symbols and point the dialog at that path they should resolve. Should be a one-time thing; after that VS will remember the path for you.

[Zelex]

ok, gotcha. How do I get the PDBs to load properly?

[jsyarrow]

To run from VS you need to get content files into a location where the temporary deployment can read them. This can't be the standard UE directories since the UWP sandbox prevents access. Typically this means running an editor build to do cook-on-the-fly, and then pointing the UWP app at it to stream the content. To do so, you need to set some 'command line' parameters, which for UWP means dropping a UE4CommandLine.txt in your Binaries/UWPxx folder (this should automatically get copied into Binaries/UWPxx/AppX during deployment). You can borrow the UE4CommandLine.txt file that automation creates for you when running from the editor with cook-on-the-fly (it's in Saved/StagedBuilds/UWP), though it contains more than you need. The important portion is

-filehostip=127.0.0.1

You can also borrow the instance of the cook server that the editor spins up in order to provide the content.

Alternatively you can pre-cook everything offline and then manually copy your cooked content into the Binaries/UWPxx/AppX location.

All this is a good reminder that we still need a FAQ posted to GitHub.

[Zelex]

ok, so that works when I launch from the editor now which is fantastic!

When I debug from VS though it now runs the game, but crashes almost immediately with no symbols. Log says:

Assertion failed: HasFoundDataDirectory [File:E:\rad\MICROSOFT_UWP_UNREAL\Engine\Source\Runtime\Core\Private\Internationalization\ICUInternationalization.cpp] [Line: 128]
ICU data directory was not discovered:
../../../UE4_UWP/Content/Internationalization
../../../Engine/Content/Internationalization
UE4_UWP-UWP32-Debug.exe has triggered a breakpoint.

[Zelex]

ahha! Thanks! will check that out!

[jsyarrow]

Thanks, that's super helpful.

Your VS build output shows an attempt to deploy two different projects, UE4_UWP (which succeeds) and UE4Game (which fails). When you hit Build Solution for a UWP platform there's no filtering of game projects for whether or not they've configured UWP support. So if you're not interested in running UE4Game on UWP you can ignore its errors, or else limit the scope of your build to the project you care about rather than building the entire sln.

Your editor problem is different. You ought to be able to work around it by providing a non-empty Description string for your project (in the Project Settings->Description page).

[Zelex]

Actually, let me revise the above post. Launching from the editor gives me this error

[Zelex]

Its a shame I can't just run the executable. Then I can avoid all this stuff and get back to programming!

[Zelex]

No I have no idea. I noticed that it created a pri file as well, but from the log it clearly doesn't work for some reason.

Yes, this is when I build from VS, though launching from the editor does the same. Building a package however fails for some kind of signing nonsense, but that is going to be my next thread once I resolve this one! lol

To confirm: when you get this error you're attempting to build/run in Visual Studio, not in the Unreal Editor?

Meanwhile I remain perplexed. The AppxManifest.xml file you provided validates for me in VS using the same schema set that UnrealBuildTool applies Specifically for the 10586 SDK these are:
Windows Kits\10\Include\10.0.10586.0\winrt\UapManifestSchema.xsd
Windows Kits\10\Include\10.0.10586.0\winrt\FoundationManifestSchema.xsd

Windows Kits\10\Extension SDKs\WindowsMobile\10.0.10586.0\Include\WinRT\AppxPhoneManifestSchema2014.xsd

Additionally I've confirmed that I'm able to manually run makepri against that file + a Resources directory and get valid output. I do see that your folder contains a resources.pri, which suggests that makepri succeeded at some point. Any idea what might have changed?
