Convert unity .cs files to Godot 4 Scripts

This is a proof of concept for converting unity scripts to godot. It's far from perfect, but might still be useful to some.

It differs from unifree in that instead of using AI, it parses the c# code and walks the AST to translate it in GDScript, more or less. This means it is deterministic, lightweigt, fast and works off-line. Furthermore it's relatively easy to make specific changes to what output it generates.

Feel free to pick this up and make it your own project as I've no plans to develop this any further. If you do, please let me know so I can add a link to your project in this readme.

Usage

If you have dotnet installed, you can run it using:

dotnet run godot tests/Player.cs

There's also a debug mode, which basically prints the AST.

dotnet run debug tests/Player.cs

Output is send to stdout

Example

Unity                                                | Godot
---------------------------------------------------- | ---------------------------------------------------------
