ArcadiaGodot VS Arcadia

To follow on what I was saying before about editor integration with REPLs, you can actually take it even farther than those simple examples. Clojure, for example, provides the ability to start a network-based REPL (nREPL) inside a running application. You can connect to it and view, change, or add to the program's state in real time while building your application. Combine that with the ability to send code from your editor into a REPL that I mentioned, and you get stuff like this where you can evaluate Clojure code on-the-fly in Unity. (Also possible with Godot.)

Nice work. Out of curiosity, though, why did you go that route instead of the Arcadia Godot port? Was there something missing or wrong with that, or did you just want to see if you could get JVM Clojure working specifically?

For what it's worth, Godot can do the same: there's a Godot version of Arcadia for using Clojure, and Godot F# tools takes some of the tedium out of using F#, though you have to make a small tweak to the .fsproj file it generates because the Mono assemblies moved. It works via a cheesy little hack: you make a C# script in Godot that's just an empty class that does nothing else but inherit from an F# class, and the F# project builds at the same time by adding it as a dependency of the Godot-generated .csproj file. Godot doesn't know anything weird is going on and it just kind of works :)

Arcadia uses ClojureCLR to work with Clojure in unity. Also Godot engine version.

If ECS gets too boiler-platey for my liking I might try some of the "don't use MonoBehaviours" approaches people have suggested, perhaps with F# bundled into a .dll. I also saw that some mad scientists had bridged the gap between Clojure and Unity via a framework called Arcadia - we'll see!

arcadia adds clojure (a lisp) to unity as a scripting language. You get to use a very good and well documented 3d game engine while still scripting stuff in your game in a lisp. there's a godot version too. The blender>unity/godot pipeline is pretty easy and documented. However, these game engines themselves are a lot to learn for your first game, especially if you're doing unorthodox stuff with them such as using lisp you won't find many tutorials.

Nowadays, Clojure can be used for this sort of stuff. Arcadia has been used to make real world games. Lead developer gave a talk about it a few years ago.

Clojure started out on the CLR before the decision was made to focus on the JVM instead, and some people still maintain an unofficial ClojureCLR port. Some people used that to make Arcadia, which builds on ClojureCLR to make it work in Unity. Here's an old video of someone Clojure's REPL-driven development to make on-the-fly scene changes, kind of cool.

Arcadia uses ClojureCLR to work with Clojure in unity. Also Godot engine version.

My understanding is that the Clojure community points everyone to Arcadia[0] since it's maintained and a bit more public about what their exact goals are. Unfortunately, neither are terribly well documented and so I've not personally used either
