#+TITLE: Lil Shooter

A small godot with clojure prototype.

Originally, this was a quick prototype implemented in gd script following this

click-baity tutorial: "Make a 2D Top-down Shooter in just 10 Minutes"

A few months later, I discovered ArcadiaGodot:

https://github.com/arcadia-unity/ArcadiaGodot, but I couldn't find many example

projects - so I refactored all the .gd scripts here into clojure.

It went pretty well! Most importantly, you are able to start the game and

connect to it via nrepl, and develop/debug most everything from there. It is a

delight!

There are some caveats - some of the usual tricks do not work, at least not out

of box. As of yet, jump to definition and auto-completion are not supported.

It's also slightly tedious to reconnect to the repl whenever you want to reboot

the game (though you can just reload the scene from the repl).

Another issue is stacktraces and errors in general - they don't yet include a

precise file and line number, but do at least show the namespace and function

call responsible.

There was one point at which my game was consistently freezing - I had captured

a game node (a bullet) in an anonymous function, the bullet was being destroyed

elsewhere, and the game was just locking completely. (The solution was wrapping

it in a WeakRef, which is probably the right C# answer anyway.)

That being said - I'm still pretty excited to take this to a larger game. Being

able to write and debug in a comment block makes for a damn good feedback loop,

as opposed to the tiresome read-docs, edit-code, restart, recreate-state.

* Notes

You'll need Godot built with Mono - see

https://github.com/arcadia-unity/ArcadiaGodot for a link to godot's docs for

handling that.
