Atmospheric Shaders, Rocket Launches, and Factory Games

2025-04-21

0.16.0-rc.5 is currently out and looking likely going to be the last release candidate, which means the 0.16 stable release is close and mostly waiting on some final release notes. There's already exciting PRs for 0.17 starting to line up but we'll wait until they land to talk about them.

In the meantime merges to main are in a pre-release stability slowdown with only the final small bugfixes having made it in in the last week before rc.5.

We still have some amazing showcases this week including atmospheric shaders, rocket control launches, and the return of Flash! and crates are starting to release no_std compatible versions, meaning you could potentially start using multiplayer networking on constrained devices.

Scene Viewer

scene viewer

racecar model from Kenney's Car Kit

Bevy's examples directory is large, containing approximately 300 examples of well-kept up to date code exploring various features of the engine. In those examples, some are of helpers like camera controllers and others are visualizers. One such directory is the tools directory, which contains a gamepad viewer and a scene viewer. In #18828 there was a small change to the scene viewer that allows it to use a gltf file from anywhere on your filesystem, so you can pull a scene in from any gltf on your system.

Crates

New releases to crates.io and substantial updates to existing projects

bevy_shuffle_bag

crate_release

bevy_shuffle_bag provides a "shuffle bag" implementation. A "shuffle bag" is a collection of items that can endlessly be picked in a random, non-repeating order.

use bevy::prelude::*;
use bevy_shuffle_bag::ShuffleBag;

let mut rng = rand::rng();
let mut treasure_chest = ShuffleBag::try_new(
  [
    "gold",
    "armor",
    "sword"
  ],
  &mut rng
).unwrap();

let loot = treasure_chest.pick(&mut rng);
println!("I just picked up a {loot}!");

Basic Bevy UI text input using cosmic text.

A number of the core text-editing basics are implemented, including undo/redo and cut/copy/paste, but features like rich text and responsive sizing are not currently.

crates.io

aeronet 0.14.0-rc.1

crate_release

This is a release candidate of aeronet, an ECS-native low-level networking library for Bevy which is compatible with bevy_replicon.

0.14 is a super interesting release, bringing no_std and no_atomic support, which in turn means full, high-quality reliable/ordered messaging + replication networking stack on your ESP32 and Game Boy Advance support.

0.14 also brings Steam networking socket support.
