This github action turns a c# project into a Unity3d project.

This is needed because unity can't use a classic c# project directly, it needs the meta files and an assembly configuration.

• A pure c# project does not have meta files for files / folders
• Some files are not used by unity because they are ignored or generated by unity (sln, csproj)

The action will open your repository looking for a unity3d-packageConfiguration.json and unity3d-packageFile.json on the root of the project. It will output the unity3d-packageFile.json directly as a package.json expected by UPM and using the configuration will traverse the repositorty and create the necessary meta and asmdef files that unity will use.

Sample unity3d-packageConfiguration.json file:

{
  "AssamblyConfigurations" : [
    { 
      "Assambly": "ManualDi.Main",
      "AssamblyDependencies" : [
      ],
      "Guid" : "2831785f1fa04efeb10b7d72b2e32628"
    }
  ],
  "IgnorePaths" : [
    "[Bb]in/",
    "[Oo]bj/",
    ".git/",
    ".vs/",
    "ManualDi.Main.Tests/",
    "ManualDi.Main/Properties/",
    ".github/"
  ]
}

Looking at the confguration we can see

• AssamblyConfigurations: Defines what will be the contents of the asmdef files
• IgnorePaths: Array of string paths using the gitignore format to define what paths should be ignored

The guid of the meta files will be random

Are created when a csproj files is present. The contents of the asmdef asset file are defined on the configuration. The guid of the asmdef meta is defined on the configuration.

The action currently has 2 parameters

• inputPath: defaults to the root of the repository ./
• outputPath: defaults to ./OutputUnity3dPackage/

This project is currently beeing used in PereViader/ManualDi.Main

• https://github.com/PereViader/ManualDi.Main/blob/main/.github/workflows/publish-unity3d-package.yml

Notice the json files at the root of the repository

The publih-unity3d-package workflow transforms the c# project and then uploads it to the same repository on a separate branch named upm. The branch is completely unrelated to the development branch to keep it clean
