Exporting for Universal Windows Platform¶
There’s no extra requirement to export an
.appx package that can be
installed as a Windows App or submitted to the Windows Store. Exporting UWP
packages also works from any platform, not only from Windows.
However, if you want to install and run the app, you need to sign it with a trusted signature. Currently, Godot does not support signing of packages, so you need to use external tools to do so.
Also, make sure the Publisher Name you set when exporting the package matches the name used on the certificate.
Limitations on Xbox One¶
As described in the UWP documentation:
- Submitted as an “App”
- available memory is 1GB
- share of 2-4 CPU cores
- shared access of GPU power (45%)
- Submitted as a “Game” (through Xbox Live Creators Program)
- available memory is 5GB
- 4 exclusive CPU cores and 2 shared CPU cores
- exclusive access to GPU power (100%)
- Exceeding these memory limitations will cause allocation failures and the application will crash.
Creating a signing certificate¶
This requires the
Pvk2Pfx.exe tools, which come with
the Windows SDK. If you use Visual Studio, you can open one of its Developer
Prompts, since it comes with these tools and they can be located in the path.
You can get more detailed instructions from Microsoft’s documentation.
MakeCert to create a private key:
MakeCert /n publisherName /r /h 0 /eku "188.8.131.52.184.108.40.206.3,220.127.116.11.4.1.318.104.22.168" /e expirationDate /sv MyKey.pvk MyKey.cer
publisherName matches the Publisher Name of your package and
expirationDate is in the
Next, create a Personal Information Exchange (.pfx) file using
Pvk2Pfx /pvk MyKey.pvk /pi pvkPassword /spc MyKey.cer /pfx MyKey.pfx [/po pfxPassword]
If you don’t specify a password with
/po argument, the PFX will have the
same password as the private key.
You will also need to trust this certificate in order to be able to install your app. Open the Command Prompt as Administrator and run the following command:
Certutil -addStore TrustedPeople MyKey.cer
Signing the package¶
SignTool.exe from the Windows SDK or Visual Studio:
SignTool sign /fd SHA256 /a /f MyKey.pfx /p pfxPassword package.appx
Instalando o pacote¶
As of the Windows 10 Anniversary Update, you are able to install packages simply by
double clicking the
.appx file from Windows Explorer.
It’s also possible to install by using the
Add-AppxPackage PowerShell cmdlet.
If you want to update your already installed app, you must update the version number on the new package or first uninstall the previous package.
