0.7.0-4.1.2

The first Godot Kotlin 4 release is here!

After months of hard work, we have successfully incorporated the new features that Godot 4 offers and resolved critical bugs.
We are excited to announce the availability of this module, which we consider to be a solid starting point.
This release is compatible with Godot 4.1.2 and Kotlin 1.9.

Please note that we do not yet consider this release to be stable. There are several small features and quality-of-life improvements that we had to postpone. The most important ones to keep in mind include:

• The editor plugin is disabled, so you won't be able to build Kotlin code directly from the editor. You will need to use Gradle commands in your IDE for this purpose.
• The IntelliJ plugin lacks the local copy security check. Please remember that when retrieving core types (such as Vector2, Quaternion, etc.) from a Godot object, they are actually copies, and you cannot modify them directly.
• The API for handling Signals and Callable functions works but does not yet incorporate Kotlin-specific features, making it somewhat boilerplate to use. In the future, we plan to introduce the ability to use signals with coroutines and lambdas with Callables.
• Compared to Godot 3, many methods in the API now use StringName instead of String. For now, you will need to manually convert from String to StringName (String::AsStringName). In the future, we will implement automatic conversion from String to both StringName and NodePath.
• The editor universal app for MacOs seems to crash if not started from commandline, we don't know the reason yet.
• IOS export doesn't work yet.

We would greatly appreciate your feedback on any bugs, usability issues, or missing documentation so that we can continue to improve this project.

While the project is still a work in progress, we have already begun planning a roadmap for future improvements in Godot Kotlin: #502

If you'd like to see an example of how to use Kotlin in your Godot project, we have ported the GDQuest demo to Kotlin, and you can find it here: https://github.com/utopia-rise/godot-kotlin-3d-demo

Regarding GDExtension, we do plan to support it in the future. However, please understand that this transition is not straightforward and will take some time before it becomes a reality. Expect the next releases to be module-only.

Artifacts:
The files prefixed with godot-kotlin-jvm_editor_ are the editors.

godot-kotlin-jvm_export_templates_0.7.0-4.1.2.tpz is the archive for all export templates .
See exporting documentation on how to use it.

Don't forget to change your build.gradle configuration with the following line:

plugins {
    id("com.utopia-rise.godot-kotlin-jvm") version "0.7.0-4.1.2"
}
