If you are looking for the documentation for Godot Kotlin/Native; you can find it here.

State

This project is in alpha, it is by no means production ready.

What's not working

The items in this list are explicitly mentioned here as these will be implemented in future versions. Also consider the Api Differences section for general differences and limitations which will not be or cannot be adressed in the near forseable future or ever.

  • Each registered constructor must have a unique number of arguments, constructor overloading is not yet supported
  • No tool mode (you can set it already in the @RegisterClass annotation but it has no effect yet)
  • No plugin support, you cannot use Godot Kotlin/JVM to write plugins and addons yet
  • Only desktop OS (Linux, MacOS, Windows) and Android are supported for now

Supported languages

The only language currently supported is Kotlin. That said it is possible to support other Jvm based languages in the future. If you want to add support for another Jvm based language, feel free to open an issue and we'll explain in detail what is necessary to support another language and help you getting started with development.
