F# VS godot-proposals

F# F*

This year I've been attempting Advent of Code in my favourite programming language, F#. This is a beginner(ish) centered post about making incremental changes from the smallest possible solution to something more robust.

I can recommend polyglot notebooks in vs code, so you can mix different languages.Take a look athttps://fsharp.org/ for some project ideas and frameworks.

I have many less followers on Mastodon than in the Birdsite (40 vs 341), yet my activity has generated many more interactions than there. Not only that, among the users who decided to interact with me I counted: a co-discoverer of the Laniakea supercluster, one of the lead developers behind F#, the author of many important books on Java & JVM, plus many others. I'm literally a nobody, but this time there was no algorithm relying on relevance and engament metrics to decide what to present to each one of us.

FP devs differ based on language here. Elm, like F#, tends to encourage "a bunch of functions and types in a file". While Elm supports modules, we don't really care where it came from; they're all pure, all deterministic, the compiler tells us if it works.

The builtin fsharp collections actually are just "immutable", not persistent as you mention. (Ref: https://github.com/fsharp/fsharp/blob/master/src/fsharp/FSharp.Core/map.fs. This is just an AVL tree that returns a copy on mutations: https://github.com/fsharp/fsharp/blob/577d06b9ec7192a6adafefd09ade0ed10b13897d/src/fsharp/FSharp.Core/map.fs#L118)

You can dive into .NET ecosystem by trying F#. It's functional-first language so this should be familiar.

ReScript code is just like F# or OCAML; it doesn’t have a function parse phase like JavaScript, so we have to define our functions and types first before we can use them. That’s fine, but makes explaining the code backwards (meaning you start at the bottom of the file and work your way up), so we’ll start at our lambda handler and explain each part, regardless of where it’s defined.

F# is a JavaScript and .NET language for web, cloud, data-science, apps and more.

Also a programming joke

Godot was fine, for the most part, it's a good engine for small games. The main issue was around working together and resolving conflicts with git (Godot isn't really working and constantly kept changing IDs in resource files), and it kept losing data in scenes when the code changed so we had to rebuild things several times. On previous test games we also ran into huge performance issues in the editor when we wanted to do too much work in scenes, so we had to switch to doing most of the work in code.

The worst part was when I had to rip out a bunch of testing code that used @tool for release as it seemed to cause issues when doing a release build. The engine is generally not great when you want to follow clean software engineering (e.g. dependency injection is not possible, I opened a proposal to that end here[1]).

If we had a Mask2D, this would be super easy and straight forward.

So if that's what OP meant, clip_children property won't work. Instead OP needs to use a CanvasGroup parent and the Line2D (with CanvasItem Material in Subtract mode) and TextureRect as siblings, or any of the other methods explained here until we have a Mask2D node.

There is an open proposal to have a compile option for a LibGodot, as a Library https://github.com/godotengine/godot-proposals/issues/6267

Yes, there could be the option to open at least 2 tabs at the same time, when working with scripts. This has probably already been suggested in: https://github.com/godotengine/godot-proposals

I cannot tell exactly where the jitter is from the video, but if it is what I'm thinking of, it is a known issue, see here. There is a proposal to fix this, with tons of discussion here. Try some of the workarounds mentioned in these two links. Game looks great by the way!

It's in the release notes. Here is a link to the pull request, based on this proposal.
