Dekirisu

Hello Bluesky! 👀 I'm a #rustlang developer 🦀 who also likes to do 2d animations! I'll mainly post about games I'm developing and throw smol self-made toons at you! 🤏 My art style is heavily inspired by #anime, #cartoon and #kidlit!

Another week, another #bevymergetrain :) Lots of careful explanation and thinking on this one; I *stopped* yesterday because I could feel my eyes glazing over. Making decisions and exercising judgement is the core of #opensource and #programming. Read about mine? gist.github.com/alice-i-ceci...

Added #bevyengine 0.20 support to mevy ℹ️ some ecs/ui #rustlang macros I use 🪿 🐱 github.com/dekirisu/mevy

Migrated my modded #bevy gltf plugin to 0.20: ℹ️ simpler "gltf -> bevy" through a trait 🐱 github.com/dekirisu/bev...

Rust 1.99.1 has been released. This point release fixes a missing wcslen symbol on some targets, a miscompilation of FFI bool return values on x86_64, and a rust-lld issue on macOS. See the blog post for details: blog.rust-lang.org/2026/10/15/R...

I just released version 0.8 of Avian, an ECS-driven physics engine for @bevy.org. #physics #gamedev #rust v0.8 features faster CCD with fewer ghost collisions, contact recycling, overhauled double-precision support, large-scene optimization, Bevy 0.20 support, and more. joonaa.dev/blog/14/avia...

I'm currently migrating from #bevy 0.18 -> 0.20 (by using my keyboard to type code) wgsl -> wesl is a neat lil change 🪿

Sign up at itch.io/jam/bevy-jam-8 !

I'll slowly return during bevy 0.20 🐌

Bevy 0.19 is out now! It features Next Generation Scenes, Render Bigger Scenes Faster, Contact Shadows, More Feathers Widgets, Text Input, Richer Text, App Settings, Post Processing Effects, Improved Skinned Mesh Culling, and more! bevy.org/news/bevy-0-19

🪿 using my new grid base 🦜 a few shading changes 🐇 own embedded DB system (kinda) 🐇 ..linked with my own asset loader (for the world only) 🥷 a bunch of other changes™ #bevyengine #rustlang #gamedev

🦜 still reworking tile/grid base 🦫 ..(experimental) custom texture mapping 🪿 ..this is ONE material #bevyengine #rustlang #gamedev

🐿️ reworking my own grid/tile system 🐇 improved tile merging #bevyengine #rustlang #gamedev

searched way to long for a bug i was convinced was in my code, turns out it was a bevy bug 🫠

Migration to #bevyengine 0.18 done! 🐿️ 🐬 ..luckily less work than expected #rustlang #gamedev

More Migrations... ✨ Updated my #rustlang macros for #bevyengine 🐿️ Added feature "0.18" for mevy_ui & mevy 🐬 ..which handles the changes to BorderRadius & LineHeight 🐱 github.com/dekirisu/mevy

Late to the party, but slowly migrating to #bevyengine 0.18 🦆 Already migrated my bevy_gltf fork! I still like a #rustlang trait to configure those. 😶‍🌫️ github.com/dekirisu/bev...

Gleam v1.16.0 is out now!!! ✨ gleam.run/news/javascr...

revisiting rusty bevy gamedev fun this weekend, let's see 🦀

What @kde.org software do you like the most? 🧐 #linux #animation #art #foss #kde

How many devices have you tried #XFCE on in total? 🤔 #linux #animation #art #foss

Rustup 1.29.0 has been released! 🦀 Rustup, the tool for installing and updating Rust, will now download files concurrently and unpack them in parallel, which makes updating Rust much faster. ✨ See the blog post for all the changes to rustup: blog.rust-lang.org/2026/03/12/R...

I can't really focus on #rustlang / bevy development atm, due to some issues - e.g. throwing job applications around, that seemingly land in 'the void'. 😶 Just so u know why there were no updates the past months. 🫠

Today I'm giving a talk about Ratatui at RustNation UK! 🎉🦀🐁 #rustlang #rustnation #rustnationuk #conference

Changing my setup for an undefined timeframe: 🐧 arch linux (btw) -> #nixOS 🦆 i3wm -> sway 🐬 xfce4-terminal -> foot

Rust 1.93.1 has been released. This point release fixes three regressions that slipped into in Rust 1.93.0: an internal compiler error affecting rustfmt, a false positive in a clippy lint, and an issue with the wasm32-wasip2 target. See the blog post for details: blog.rust-lang.org/2026/02/12/R...

I'm back & decided to change things up! 🫠 ❌️ ditch QWERTY ✅️ develop & use my own smol layout ✅️ use badly cut paper as cover My #keyboard now looks like a space invader! (unintended) 👾

Just 'lost' hours of gamedev progress to PokeRogue. Lost an extremely lucky run to a water-type #pokemon that was immune to grass - didn't know that was a thing. 🦆 (And the only moves I had left were grassy 🫡)

🏞️ added environment variables: 🍃 temperature, rel. humidity & wind speed 🪿 they directly & indirectly influence various things: 🦫 ..like tire temp. warm-up/cool-down, grip, degradation, acceleration, etc. #rustlang #bevyengine #gamedev #indiegame

🔥 added tire temperatures 🪿 ..it affects grip & degradation speed 🦫 (..and indirectly other things) #rustlang #bevyengine #gamedev #screenshotsaturday

❄️ foggy winter styling #rustlang #bevyengine #gamedev

🛞 tires now have durability w/ ui 🦆 added milage ui 🐇 simpler input ui 🦫 harsh keyboard inputs can be smoothed #rustlang #bevyengine #gamedev

🌄 new daytime styling 🌲 new environment 🦜 reworked textures #rustlang #bevyengine #gamedev

Took a step back to rewrite stuff... ☠️ #rustlang #bevyengine #gamedev

👂 made a more chill engine sound ...the one before kinda annoyed me over time 🫠 #rustlang #bevyengine #gamedev #screenshotsaturday

✨ major shading/style rework 💫 (kinda merging all past style tests into one) 🐿️ rework of a few track barriers (the glassy ones) #rustlang #bevyengine #gamedev

🚗 new asphalt style 🌄 re-added a simple skybox (just a gradient) #rustlang #bevyengine #gamedev

👂 first try of skidding SFX 🦆 ..and suspension compression SFX 🐿️ (..or however one would call it) 🐦 made the engine sound more 'futuristic' #rustlang #bevyengine #gamedev #sounddesign

🛞 finished the first version of skid-marks #rustlang #bevyengine #gamedev

🛞 defined where & when skid-marks should be #rustlang #bevyengine #gamedev

Worked on deki-drive a bit! 🐦 bevy: 0.16 -> 0.17 🍃 avian3d: 0.3 -> 0.4 🦜 style changes 🛞 physics changes #rustlang #bevyengine #gamedev #screenshotsaturday

Rust.

Rust 1.91.1 has been released. This point release fixes two regressions that slipped into in Rust 1.91.0: one that affects Wasm, and one that affects Cargo on illumos. See the blog post for details: blog.rust-lang.org/2025/11/10/R...

Also migrated my modded GltfPlugin to bevy 0.17 🦜 does the same as the original, but: 🐿️ ..has easy access points to change stuff 'on load' through a trait 🐱 github.com/dekirisu/bev... #rustlang #bevyengine

🐿️ changed day/night lighting #rustlang #bevyengine #gamedev

🦀 bevy/mevy UI Hot-Reload Experiment 🐦 Had a weird idea how to do bevy_ui hot-reload. ..without a dioxus or bevy feature 🦆 Here's a small test where only position, size & border works. 🦀 #rustlang #bevyengine

I was wondering how it would look like when: 🦞 not using bevys pbr material 🦜 making my own material (the darker looking one) (would 'lose' lighting/reflections etc.) #rustlang #bevyengine #gamedev

🐦 Mevy now works for #bevyengine v0.17 too 🐱 github.com/dekirisu/mevy

Rust 1.91.0 has been released! 🌈 🦀 This version brings you tier 1 support for aarch64-pc-windows-msvc, warnings for dangling pointers to locals, new methods on AtomicPtr, array::repeat, BTreeMap::extract_if, const TypeId::of, and more! Check out the announcement: blog.rust-lang.org/2025/10/30/R...

Looks almost the same, but: 🦆 less draw calls (partially custom GPU instancing) 🐇 less entities -> less transform propagation etc. 🐿️ less data cloning 🦞 downside: disabled 'indirect drawing' #rustlang #bevyengine #gamedev

It's crazy how much optimization-potential there is using bevy & rust 🦀 Dove a bit more into performance profiling and the engine source code - got a few ideas that should improve performance (on CPU & GPU) by quite a lot for my use case without many trade-offs (besides the development time). 🐿️
