I found a #bug in my #zsa Voyager. I'm not sure how to patch it... 🤔

The results for my #LDJam game are in: I ranked 60th in mood and 82nd in audio out of 1391 games. This was my first time composing music, my second time using my own #rust engine, and a huge leap from my last jam!

You can try the game for yourself on the web: caer.cc/app/ld58

Poster for Caer's Ludum Dare #58 game, titled "recollect". The poster lists several of the games rankings: 60th in mood, 82nd in audio, 136th in innovation, and 397th overall out of 1,391 submitted games. The poster contains a brief description of the game: "In a world without sound, guide recco and collect records of music from a civilization long since past." The poster contains summary accolades from several of the Ludum Dare reviewers, including the following statements: "a rare and beautiful audio experience", "a moody abstraction of exploring the unknown", and "an atmospheric buildup akin to 'Outer Wilds'".

I made another (tiny) game with my custom #rust engine as part of the 72-hour Ludum Dare Game Jam!

"re:collect: In a world without sound, play as Recco, and gather lost records of music from a civilization long since past."

It's been a bit, Bluesky! Last month, I made my first-ever game during @ludumdare.com #LD57: Layered. It's a puzzler inspired by deep neural networks' hidden layers, built using my own #rust engine based on #macroquad. Now I'm working on "finishing" it~

A poster for a game titled "Layered", submitted as part of the 57th Ludum Dare Game Jam. The poster shows a screenshot of the game's colorful isometric tiles, captioned with: "guide a wandering data through the hidden layers of a deep neural network in this isometric puzzle game". The poster displays a series of accolades: The game placed 529th overall out of 1599 entries, placed 238th for most innovative, and 249th for most fun. Players described the game as "innovative and well executed", "a satisfying challenge", and "cute, moody, and soothing". The bottom of the poster contains a link for more information (https://www.caer.cc/logs/ldjam-57/), and the developer's "With Caer" logo mark.

Happy New year, Bluesky! My New Year's resolution is a crisp 160x144px. hbu?

Image of a circuitboard with an E-Ink display showing a 160x144px image of Caer's logo, accompanied by the HEX-encoded text of the BLAKE3 hash of a super-secret message. The text is 611AB930A7E69D35BDA24280FCCCA3956E628E328D5DB0CA0579D1A2C669597E. Can you guess what it's the hash of? The hands holding the circuitboard in frame have painted nails, some are painted brown with gold flaking, and another is painted periwinkle with golden flaking. In the background, a ceramic coffee mug with a fox is visible, along with the Alicorn Systems logo, a book, and a card.

I soldered my first header pins today! Thanks @adafruit.com for the lovely parts and tutorials that gave me the confidence to give this a go~

Want to try an unstable Rust feature without installing an entire Nightly toolchain? Use `RUSTC_BOOTSTRAP=1 cargo` instead of `cargo +nightly`!*

*This flag disables `rustc`'s stability guarantees. Sharks might eat your binary. But it sure is nifty!

#rust #rustlang #code #programming #opensource

I’m making a 2.5D game engine in Rust for fun, and got super confused when the isometric cube I drew didn’t look “right”.

Today I learned: Most “Isometric” game art is actually drawn in a 2:1 “Dimetric” projection.

(real artists: plz correct me if I’m wrong)

Picture showing an isometric cube overlapping a 2:1 dimetric cube, highlighting the width difference between the two projections.

Hi Bluesky! I'm Caer; I #code and I write about code.

For my first post, here's my favorite #RustLang hack: Combine `#![doc]` with `include_str!()` in `lib.rs` to reuse a `README.md` as a crate's docs. ❤️
