Simulo, Bean Defender, and Toroban!
2025-12-08
This week debugging applications with multiple cameras gets easier with a new debug_group feature implementation.
While #22016 introduces TypeData dependencies, which means type data like Resource can depend on Component. This in turn makes the following code:
#[derive(Resource, Reflect)]
#[reflect(Resource, Component)]
struct Thing;
reduce to
#[derive(Resource, Reflect)]
#[reflect(Resource)]
struct Thing;
Showcase
Bevy work from the #showcase channel in Discord and around the internet. Use hashtag #bevyengine.
Pathfinding Playground
showcase
A visualizer for pathfinding algorithms powered by WASM. You can use any language supported by WIT to generate API bindings, run your pathfinding algorithm and see how it works
Cyclone
showcase
A cyclone built with shaders and bevy_volumetric_clouds in the background.
There are three volumes: the cyclone sheath, the ground cloud, and the orbiting debris field. The cyclone meanders within a fixed radius. It is controlled by wind speed linked to bevy_volumetric_clouds. As you can see, it is a windy day.
bevy_reflect_inspect
showcase
A custom Reflection-based editor that suits the authors use case. There won't be a release but it is open source.
Simulo on Steam!
showcase
A 2D physics sandbox game where you can build and share creations. Features include a simple and intuitive interface, temperature, and destructible ragdolls.
Uses bevy_flair, bevy_blur_regions and TypeScript.
Bean Defender
showcase
Inspired by Bad North, this 3d Bevy game as build using Blender alongside Avian for physics, bevy_landmass and bevy_rerecast for pathfinding.
csv_god_game
showcase
A small god game powered entirely by CSV files. Made mostly for the purpose of experimenting with CSV-based workflows with bevy_asset. You can modify the items and recipes in the two CSV files (in assets) to turn this into an entirely custom silly god game.
Toroban on Steam!
showcase
Toroban is an infinitely wrapping puzzle game, now available on Steam!
World Generation with fast_surface_nets
showcase
World generation using fast_surface_nets with streaming and collision.
Crates
New releases to crates.io and substantial updates to existing projects
bevy_nested_tooltips
crate_release
Inspired by the Tooltips of Crusader Kings 3 and Victoria 3
A library for creating headless(unstyled) tooltips that can be arbitrarily nested and highlight other nodes.
lore
crate_release
A small logic programming engine (effectively the backend of a system like prolog) inspired somewhat by flecs' query engine
bevy_malek_async 0.2
crate_release
bevy_malek_async is a async runtime agnostic crate that allows you to interact with the bevy ECS from any async task. Be it tokio, bevy's task pools, or something else. It contains a single low-ish level primitive to worry about world_id.ecs_task().run_systems(Schedule, || {}).await
This lets you run something like a bevy system in an async task but it's actually more powerful than a normal bevy system!
Importantly you can pass local mutable state inside and outside of this closure, something you cannot accomplish with normal bevy systems!
// Showcasing how you can mutably access variables from outside the closure
let mut my_thing = String::new();
world_id.ecs_task::<()>().run_system(PreUpdate, |()| {
my_thing.push('h');
}).await;
my_thing.push('i');
The implementation of this is 0 copy, and works with non-send data like &mut. It is implemented with extremely high level performance considerations so should be suitable for all sorts of very expensive logic that send based, channel based, or copy based async interactions are not viable for.
Bevy Replicon 0.37.0
crate_release
bevy_replicon is a crate for server-authoritative networking.
This release features a new visibility system. It's component-driven, so you don't have to maintain visibility separately from your gameplay logic. And it now supports both component and entity visibility.
bevy_live_wallpaper v0.1.0
crate_release
bevy_live_wallpaper is a Bevy plugin that renders your scene into a desktop background. Currently Wayland, X11, and Windows are supported.
aalo 0.1
crate_release
aalo aka bevy-inspector-haalka is a bevy_ui-native inspector built with haalka which aims to port much of the behavior of bevy-inspector-egui to bevy_ui
