Customize how tweens.gd fits into your project, or work on the library itself.

Using NuGet together with the GDScript addon

To use both languages while keeping NuGet for C#, exclude the addon’s C# sources in your game’s project file to avoid duplicate types:

<ItemGroup>
  <Compile Remove="addons/tweens_gd/csharp/**/*.cs" />
</ItemGroup>

Keep one C# implementation

Alternatively, omit the addon’s csharp/ directory. Keep its GDScript files and native binaries together.

Working on the library itself

To build the library together with your game, clone the repository and add a project reference instead of installing from Godot Store or NuGet. Adjust both paths:

dotnet add path/to/YourGame.csproj reference path/to/tweens.gd/csharp/tweens.gd.csproj

If you also keep the addon for GDScript, exclude its C# sources.

Importing without the editor window

To run a fresh checkout headlessly, first run godot --headless --editor --import to register the extension and populate the script-class cache.

First-import crash

Godot 4.7.2 can crash on exit after the first headless import registers the extension. Rerun the import before continuing.
