defold VS godot-jvm

Yes that King, the ones who made Candy Crush. They made a game engine source available (open source with the exception that you can't create a competing game engine from it) with full 2D capabilities, tile map support, spine support, shaders, particle systems, UI editor, scene editor, Box 2D and Bullet for physics, hot-reloading, profiling & debugging tools, etc. It also has basic 3D support, although I wouldn't recommend it for anyone making a primarily 3D game. It's written in C++ and uses Lua as the scripting language, and it's easy enough to write native extensions for any platform's language of choice.

looks very neat, but it doesn't really get more OO than JavaFX, does it ? would you call this code functional & idiomatic in any relevant sense of the term? https://github.com/defold/defold/blob/dev/editor/src/clj/edi...

Maybe that's typical in gaming situations, but it has a weird license: https://github.com/defold/defold/blob/1.3.4/LICENSE.txt ("the Defold License version 1.0")

If you paint by some numbers, the Defold repo (https://github.com/defold/defold) has 1k issues, and only 14 prs open, whereas the Godot repo (https://github.com/godotengine/godot) has 5k+ issues and a whopping 1.1k prs open. And a difference of 1500 contributors on Godot, versus 37 total contributors on Defold.

You obviously know this since you linked a Swift bindings project, but for others reading who may not be aware: Godot officially supports multiple languages ("GDScript, C#, VisualScript, and C++ and C via its GDNative technology"[1]), but other languages are supported by the community.

In particular, a sibling comment mentions Kotlin. The docs[2] link to a project that adds Kotlin bindings https://github.com/utopia-rise/godot-kotlin-jvm

There are bindings for godot btw, native and jvm ones

Not really. We started one just now (https://github.com/utopia-rise/godot-kotlin-jvm-demo) but there's not much in it yet. A better starting point (though a bit harder to understand at first) is the harness folder in the repo for now: https://github.com/utopia-rise/godot-kotlin-jvm/tree/master/harness

The gradle dependencies are published to mavenCentral and the prebuilt engine as well as the prebuilt export templates can be found in the github release here.

Please read through the whole Pre-Alpha instructions page (https://github.com/utopia-rise/godot-jvm/blob/master/docs/src/doc/pre-alpha.md) to see what's working and what's not and how to get started.
