I remember really disliking the Minecraft ladder climbing mechanics way back when I first played the game Now I'm really struggling to remember what it was I didn't like... I've gotten so used to them now

I made a Pokémon ROM hack and wrote about it https://felixjones.co.uk/2025/04/30/pokegreen.html

Yes my earlier post was in reference to something that happened at work today. Yes I failed to bury the evidence of it. Yes I am ashamed.

"Code looks great Felix, but can you remove the check that gives 26 netherite ingots to any player spawning with the name 'Xilefian'?"

I've been trying out some Game Boy pixel art on a Pokémon ROM hack (based on shinpokered) Here I've implemented an optional girl player based on the manga character

I enjoy the "I recreated Minecraft" YouTube videos for the journey of learning the author goes through, but there is a pattern where they decide to spin it into their own game they somewhat combine Minecraft with some existing genre It's a legitimate way to come up with a new game, but when you […]

Totally forgot it's snapshot day today https://www.minecraft.net/en-us/article/minecraft-snapshot-25w15a This one has the Locator Bar, a feature I've been working on, and we're open to feedback so I'm all ears!

Really happy reading player comments regarding the Vibrant Visuals shadows, I think it's a point of career pride for me 🥲 Loving the comments of "how come no-one has thought of this before!" I wish we had written down or recorded some of our very early musings of an idea for visual direction […]

I'm quite envious of the Minecraft Java team's opportunity to implement Vibrant Visuals with a clear target of "this is how Minecraft looks" Minecraft's technical design has so much opportunity for very novel solutions, and the ingenious art direction of Vibrant Visuals wants for that

What did everyone think of Minecraft Live? Specifically my appearance at the end 🤔

"Yeah I know Minecraft commands" _proceeds to type a command for the other Edition_ Easy and consistent way that I embarrass myself at work ⛄

I was testing some Minecraft changes just now and panicked because a large village seemed to spawn with no villagers 😱 I was racking my brain over what could have broken Minecraft villagers, but then I heard a "Hrrrm"; turned around and a nitwit was staring at me for being a dorkus

I ported Minecraft's Codec API to C++23 and it gave me zero overhead serialisation https://felixjones.co.uk/2025/03/01/serialisation.html

I really like the syntax of our Java DataFixerUpper library, so I tried replicating something similar in C++ with full compile-time support and I'm very happy with what I've landed with: struct foo { int a; unsigned int b; char c; }; static constexpr auto […]

I have a definite philosophy difference between writing Java and C++ The C++ I write focuses on containers: how is data stored and accessed My Java code, meanwhile, focuses on encapsulation: how are methods interfaced with

Java Edition's entity attributes continue to impress me. I've been experimenting with what can be done and my prototype of "trigger a breakpoint if attribute FELIX > 1" has much flexibility in how the player triggers it Absolutely no effort required from me other than the if statement

Been using C++23 with inline assembly and I have an IRQ handler that puts a user defined handler functor into `r0` and performs a `thiscall` with the IRQ flags in `r1` and a pointer to the `operator()` in `r12` Shockingly my `std::function` style template compiles all the way down into a […]

Using C++23's deducing `this` to pass-by-copy is proving extremely useful for inline thumb16 assembly The `LDM` and `STM` instructions write back to the address register, so a const will be mutated: forcing pass-by-copy and admitting to the compiler "this will be mutated" gives optimal output […]

How the heck do I submit a GCC bug report? I've been waiting for this one to be fixed for years and it's still an issue https://godbolt.org/z/Yd66zqrGv

I've been trying out C++23 features and it seems like the changes so far are ideal for embedded systems

I saw some notable figures lamenting SLI not being a thing, but in its stead we have heterogeneous GPU support baked into Vulkan, allowing per eye GPU rendering as well as alternate frame rendering What we're missing are games/engines that take advantage of this, and the fact that I need to […]
