In my C code I've gotten a little obsessed with "automated" bitfields, after discovering that you can use the auto-count trick in an enum to determine how many bits are needed to hold the values.
Is there a better way to do this? I'm curious if anyone else has explored this...

thought I'd post this mid-June because I don't know exactly when, but I started my game development journey 20 years ago!
I was 9, my Dad showed me GameMaker 6, and I was hooked. I wonder what younger me would think of where I am today...
never give up! never stop learning!

I forget how much longer it takes to do complex light-transport with things like gems haha This came out pretty okay given how fast I did it - bit rough though

Episode 5.5 is out of my little Minecraft series!
I just wanted to get some Tuff and make decent progress on the house before the busyness of work kicks in this coming week!

For example, an RGBA 4K texture would be about 33MB in size. If you open up your Task Manager and look at how much memory different apps are using this should give you some perspective.
I could have 10 4K static arrays in my code, no mallocs, and it's still less than 1GB of RAM.

I find it fascinating how different you have to think to avoid Object-Oriented Programming.
In C there's many moments where you realize "Wait, a fixed maximum array will be fine", and you end up saving overhead and complexity.
Not using any malloc/free is quite... freeing

Weighs barely anything, and feels as hard and as strong as metal.

Here's what it looks like assembled + some holes for weight reduction.
I used the thumb-wheel as the main wheel since it's a lot lighter, and still works since it has a little magnet in it.
With the wheel it's 36.4 grams!

software rendering is so fun, you often don't need sprites - you can just have a function that renders the pixels exactly how you want, pixel by pixel

I wonder if there's any benefits not having tabs for multiple images you're editing, and they all just exist in one big space...
This would be quite useful for referencing or dealing with multiple textures 🤔 hmmm

wouldn't it be cool to have a hyper-minimal pixel art program that's able to use the most efficient OS methods to render directly to the window to reduce the overhead as much as possible, prioritising memory and speed, while also being <30KB for the entire executable?

But I enjoyed blabbering about what was on my chest; I mention NYKRA quite a lot near the end.

So I made my own build automation which makes one that's as minimal as possible!

it's interesting how often ideas come to me when I'm sitting in silence at a park/garden/forest.
I realised a very efficient and minimal way to do tile-based shadow-casting (in C) that's completely software rendered - not using the GPU at all.
