defold VS OpenJK

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.

JK XR is a VR port of the Jedi Knight games using OpenXR (the open standard for virtual and augmented reality devices) and is based on the excellent OpenJK port, originally forked from: https://github.com/JACoders/OpenJK

Although you'll probably need to install OpenJK anyway afterwards.

It's still active.

Pro tip the source code was released a few years ago and some fans made some updates: https://github.com/JACoders/OpenJK you only need to download the files from Amazon and then execute from the openjk to enjoy the game fully on modern systems, works with mods too.

There's the OpenJK engine for those. Same way people can play them on the Pi.
