He also did a live coding demo showing off this VR scripting concept. Having such a fast iteration cycle is very compelling. Hopefully at least some Javascript version of this will exist, even though this seems like a perfect application for a Lisp.

I wish he did live coding. Jonathan Blow's Twitch channel (naysayer88) is very compelling. Carmack's would be as well.

Racket is the language used in the project, I think it should rather be "John Carmack’s VRScript Samples in Racket" for the title.

For anyone interested in how I gathered these: I noticed a versioning pattern from the snippets he was sharing online. I started poking around and tried to put together a git history of changes by guessing version filenames on oculus' s3 bucket.

So if you do `git log --reverse -p c9bd14f361cc4e537425f6d634367415059ad5e3..HEAD` you can see a snapshot of some of his vrscript development

Do we know if he or the other oculus team members are still using racket?

If I remember correctly, Facebook told him to drop Racket and use JavaScript instead.

I can't get these to run with Racket v7.2.0.3. Undefined functions are called that are not in the code in your repo. For example: set-local-client-state!

I initially read the title as "John Carmack's VBScript Samples" and I was very perplexed as to when would have John Carmack ever had to mess around with that...

What was the general idea / purpose behind these scripts? I never thought I'd be interested in looking at Racket again after my undergrad at NEU.

Good to see Scheme/rkt at work.

John wanted racket to be the main scripting language for vr apps that are lightweight and don't need a lot of horsepower. https://youtube.com/watch?v=ydyztGZnbNs

Trying to explore gamedev in Racket myself so cool to see the matrix related stuff in https://github.com/jb55/vrscript-samples/blob/master/vr.rkt

They are switching to JS from Racket, which is a shame. It would be great if one could just do

#lang javascript

and use the same stuff. Truffle/Graal is a much better and complete and performant alternative to Racket now for implementing languages. You write a normal AST interpreter and add annotations for optimizations.
