# This build pipeline is designed for ARM UWP projects, running Unity 2019.x or later, with MRTK Foundation 
# If using 2018.x or earlier: Change unity.installComponents to 'Windows, UWP_IL2CPP'
# If not using MRTK Foundation: Change unity.executeMethod to your build method (We recommend basing off the one in MRTK Foundation)
# If you want to build x86 UWP builds: In theory should just be able to change vs.appxPlatforms, but it's a TODO

# This pipeline depends on secret variables that you must define within your Azure DevOps!
#   unity.username  = <Your Unity account username / email>
#   unity.password  = <Your Unity account password>
#   unity.serialkey = <The serial key for your Unity pro licence>
# Without all three, this pipeline will fail to run!

# Unity will be licensed, used, and then unlicensed during the unity and unitytests jobs in this pipeline.
# A Pro license works on 2 machines, and in theory this pipeline will only use one licence at a time.
# However, should there be unexpected errors and deactivation doesn't complete properly, you may need to log into your Unity account and deactivate all.

# Variables predefined for this build process:
variables:

  # If true, will run tests, otherwise skip them. If you do not have tests, set to false to increase build speed.
  runTests: false

  # The path to the folder which contains the Assets folder of the project.
  # If your Unity project is located in a subfolder of your repo, make sure it is reflected in this.
  unity.projectPath:        '$(System.DefaultWorkingDirectory)/'

  # If you are using Unity 2019 or later, leave this alone!
  unity.installComponents:  'Windows, UWP'
  # If you are using Unity 2018 or earlier, comment out the above and uncomment below:
  #  unity.installComponents:  'Windows, UWP_IL2CPP'
  # Explanation: In Unity 2019 and later, .NET scripting was removed. You no longer need to specify 'UWP_IL2CPP', it's now simply 'UWP'!

  # The build method of the Unity project. This assumes you have MRTK in your project, and uses its build script.
  # If you want to customize your build script, change the method name here:
  unity.executeMethod:      'Microsoft.MixedReality.Toolkit.Build.Editor.UnityPlayerBuildTools.StartCommandLineBuild'

  # Are we buolding an .appx for x86 or ARM?
  # TODO: Theoretically, could expect to use 'x86|ARM' to build for both HL1 and 2, but yet to get that to work.
  vs.appxPlatforms:         'ARM'

  # I would not expect you to have to change the rest of these unless you had a special reason:
  unity.targetBuild:        'WindowsStoreApps'
  unity.outputPath:         '/Builds/WSAPlayer'
  unity.editorPath:         '/Editor/Unity.exe'
  vs.packagePath:           '/AppPackages'

  # This also needs to be passed to the install template, along with unity.projectPath
  unity.installFolder:      'C:/Program Files/Unity/Hub/Editor/'
