ml-gen

MelonLoader's toolchain, but as a GitHub Action. Useful for CI builds of MelonLoader mods.

Usage

# .NET is required
- name: Setup .NET
  uses: actions/setup-dotnet@v2
  with:
    dotnet-version: 5.0.x

- name: Generate libraries
  uses: tetra-fox/ml-gen@latest
  with:
    game: among-us
    game_path: ${{ github.workspace }}/Among Us
    game_executable: Among Us

Notes

• You must provide your own game binaries. You can automate this process with tools such as DepotDownloader.
  • I personally use the Steamfetch action to accomplish this.
  • The specific binaries you need are the following:
    • Executable (e.g. Among Us.exe)
    • GameAssembly.dll
    • [game]_Data/il2cpp_data/Metadata/global-metadata.dat
    • UnityPlayer.dll (Windows runners only)
    • [game]_Data/globalgamemanagers OR [game]_Data/data.unity3d, whichever your game has. (Linux & macOS runners only)
  • You must leave the directory structure intact.
• You can figure out what your game's gameSlug is here.
• This action mimics the directory structure of a game with MelonLoader installed, with the output .dlls in the MelonLoader/Managed directory, and tools in MelonLoader/Dependencies/Il2CppAssemblyGenerator.
