Since I couldn't post the video last time, I'm trying again:

Since the beginning of January I have been working on a spare time project I started last year in the Unity engine. Now I am trying to reach the state of the prototype in Unreal Engine where I left off in Unity.

This is a small glimpse of the wolf encounter and what it should be able to do later. It is not where it should be, but it shows the intention.

Tonight I had strange dreams about state monads...

I currently have some waiting time at work, and am now trying to change some things in my #RustLang #SpareTimeProject, as I would like to try using a State Monad Transformer together with a Free Monad. I don't think that this combination is going to work for what I am trying to achieve, but after tonight I just have to try it.

And I must say, I already miss the #Lean4 Syntax. Rust is just sooooo verbose when it comes to nested generics...

After simplifying the get-function in my current #SpareTimeProject (a formally validated heap), I had to make a lot of changes as #Lean4 fails to unfold the new function definition.

However, I am very happy with the results. The inability to unfold forced me to rewrite some proofs in the formal validation, now using hand-written lemmas instead of unfolding the function definition. The new code is about 200 lines shorter than the old one, easier to read, and more robust.

A few months ago a coworker made the prediction, that once I got to know #Lean4, I would port my #SpareTimeProject over from #RustLang.

I must say, he was not wrong... I would be so tempted. Lean feels way better suited for writing a #VisualNovel Engine than Rust. However, I have already done so much Rust-specific work, that I think I will manage to resist the urge of switching language, and finish this project in Rust.
