I got real time lighting working! There are a few glitches in it but it's good enough for now.

Not exactly the the way I was hoping the wall textures would come out 😬
Monster door! (Because instead of a door it's a monster...monster...door...)
Getting the monster sprite sheet ready as I work on improving support for them in my shaders.

I finally switched the rendering of the player's wand to a sprite sheet rather than individual images for each animation frame: dkanen.com/blog/2022-08-03-s…

Introducing Swift Collections

I’m thrilled to announce Swift Collections, a new open-source package focused on extending the set of available Swift data structures. Like the Swift Algorithms and Swift Numerics packages before it,...

Fumbling along learning linear algebra with python. I didn't think I'd figure out how to make an n dimensional basis matrix without peaking at the answer. But I did it! 🎉The answer uses list comprehensions but I still love mine.

Just converting an object to an array.

Returning nulls works better when I return null 😓

The #SwiftLang magic identifiers don't seem so magical now that I know where they live: github.com/apple/swift/blob/…
Some great discussion of how #Kotlin getters and setters work with Java over on the forums. Even if you're familiar with how they work you still might pick up some useful bits: discuss.kotlinlang.org/t/are…

Are public attributes rather than private attributes with get/set methods common practice?

In the short time I’ve been learning Kotlin, I have seen this quite a lot. Is this common practice even for professional and experienced Kotlin developers?

I always get a little burst of joy when I can write a single expression function in #Kotlin with "when".
Just found that MacOS' Console now can weave logged data from different sources to help explain what is going on in your app or system. Click "Activities" to enable. See how "apsd" is linked to "identityservicesd" below:

Came across this great conference talk, youtu.be/-lVVfxsRjcY, by Christina Lee about managing state in #Kotlin by using the type system and a great explanation of illogical data structures. It has already changed my approach to writing Kotlin.

I wondered what was so great about #Kotlin keyword "const". Found out it's like "val" but inlines the value. Another neat little optimization Kotlin pulls off. Nice!
