Exporting for Universal Windows Platform

Não há nenhum requisito extra para exportar um pacote .appx que pode ser instalado como um aplicativo do Windows ou enviado para a Loja do Windows. A exportação de pacotes UWP também funciona a partir de qualquer plataforma, não apenas do Windows.

However, if you want to install and run the app, you need to sign it with a trusted signature. Godot supports automatic signing of packages with external tools.

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:

  • Enviado como um “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 MakeCert.exe and 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.

First, run MakeCert to create a private key:

MakeCert /n publisherName /r /h 0 /eku "1.3.6.1.5.5.7.3.3,1.3.6.1.4.1.311.10.3.13" /e expirationDate /sv MyKey.pvk MyKey.cer

Where publisherName matches the Publisher Name of your package and expirationDate is in the mm/dd/yyyy format.

Next, create a Personal Information Exchange (.pfx) file using Pvk2Pfx.exe:

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

Setting up automatic signing

To setup automatic signing on export you need to go to Editor Settings > Export > Uwp. From there you need to click on the folder for Signtool, and navigate to the SignTool.exe file on your computer.

After setting that up close the editor settings, go to Project > Export, and select the UWP preset. Under the Signing options click on the folder next to Certificate and go to the certificate file. Then enter the pfxPassword in the password field.

Your project will now be automatically signed on export.

If you want to sign an exported app manually run SignTool.exe and use the following command.

SignTool sign /fd SHA256 /a /f MyKey.pfx /p pfxPassword package.appx

Instalando o pacote

No caso do Windows 10 Anniversary Update, você é capaz de instalar pacotes simplesmente dando dois cliques no arquivo .appx do Windows Explorer.

Também é possível instalar usando o Add-AppxPackage PowerShell cmdlet.

Nota

Se você quer atualizar seu aplicativo já instalado, você precisa atualizar o número de versão no novo pacote ou primeiro desinstalar o pacote anterior.
