🦀 Hello World!

The Rust project now has an official presence on Bluesky! ✨

We'll be posting the same on our Mastodon and Bluesky accounts, so you won't miss anything on either platform.

An early look at the spawn platform, I'm going to be working on getting the animations hooked up next!

Here's the mark 1 server chassis for Computronium. This also has a used and DIY quality to it. We were inspired by 70s era HiFi equipment and the Atari.

Just added camera collision to Computronium! It's a really simple, but robust solution. The clipping at extreme angles still needs some work, but I didn't like the jittering in corners when I used a normal offset.

Here's the Mark 1 server rack for Computronium. It's a very ”hacked together" aesthetic that I hope a lot of self hosting enthusiasts might enjoy.

Avian is an ECS-driven physics engine for @bevyengine.org, with a focus on ergonomics and modularity.

I just released version 0.2, which includes a *ton* of new features and quality-of-life improvements. An announcement blog post with release notes can be found here: joonaa.dev/blog/07/avia...

The `matches!` macro in #rustlang gives you full pattern matching capabilities without having to write a single case match statement! You can even provide an optional guard condition!
if !matches!(server_state.get(), ServerStates::Disconnected) { return; }

I recently learned that you can use the debug print syntax in #rustlang template strings while keeping variable references inline instead of as subsequent arguments!
info!("Spawn third person camera for {:?} on frame: {:?}", client_id, frame); // eqivalent info!("Spawn third person camera for {client_id:?} on frame: {frame:?}");

Bevy is finally registered as a game engine on itch.io!

You can now label your game as "made with bevy" by adding it to its metadata.

The `run_if` run condition in #bevyengine does not short-circuit if previous conditions do not pass. If you want to avoid checking future conditions, use the `and_then` condition to chain multiple together.

#gamedev
#rustlang
app.add_systems(FixedUpdate, enter_gameplay_system .run_if(in_state(LauncherStates::Connecting) .and_then(any_with_component::<PlayerComponent>) .and_then(any_with_component::<AvatarComponent>) .and_then(any_with_component::<ThirdPersonCameraComponent>) ) );

One of the biggest frustrations I had moving out of the US was region restrictions from the Play Store.

I had to add a new payment method (for free apps) and delete my family connections.

Of course I was using family shared Drive storage which added a lot of manual data clearing to the process.

In our next Tiny Glade update we'll bump the light limit from 32 to 32k while keeping the cost more or less the same.

The small limit has been a cop out, as we didn't quite know how to render huge numbers of (screen-space) shadow-casting lights without severe performance degradation.

The `cfg_attr` attribute in #rustlang can take additional arguments that will all be applied if the first argument passes.
// both of these separately: #![cfg_attr(debug_assertions, feature(core_intrinsics))] #![cfg_attr(debug_assertions, allow(internal_features))] // is the same as: #![cfg_attr( debug_assertions, feature(core_intrinsics), allow(internal_features), )]
