Using C# with Godot Engine is powerful but at times daunting due to the lack of documentation and samples available. Thankfully there is a new example available from Chickensoft. It illustrates how to create an entire vertical slice of gameplay of a 3D platformer entirely using Godot and C#. This version required Godot 4.2 beta 5 or newer.
You can learn more about C# development in Godot using the new demo from Chickensoft, as well as the new Abandoned Spaceship Scene in action in the video below.
