Bevy at RustWeek

2025-05-19

Rustweek kicked off with a talk from Polders creator Jos Feenstra about what they've termed "Dionysian Rust". Roughly: the idea that because Rust is built on a really strong foundation of zero-cost abstractions, safety, etc you as an application developer are free to spend the resulting available resources in a quick-and-dirty way, knowing that Rust will support you in refactoring in the future.

Rustweek also finished the conference off with a talk from Alice Cecile about Immutable Components and how they came to be.

After the conference, Bevy participated in an Unconference for two days. There was a bunch of great cross-community collaboration between different Rust projects and the more localized Bevy room split into roughly 4 groups, including

  • The Bevy Book
  • New Usage Examples
  • A "Quickstart"
  • PR Review!

There were livestreams if you want to check out the talks before they're cut down for YouTube.

Many maintainers were at RustWeek so the amount of merged pull requests is low this week.

gltf physics

glTF Physics

showcase

New glTF features come up all the time, from references to physics. In certain cases a subset of the functionality of a given extension can map to existing features, such as a potential glTF physics spec to Avian colliders.

This project takes the khr_implicit_shapes and KHR_physics_rigid_bodies extensions from eoineoineoin/glTF_Physics and implements a Blender-to-Bevy pipeline.

Crates

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

bevy_ratatui_camera

bevy_ratatui_camera 0.14

crate_release

bevy_ratatui_camera is a A bevy plugin for rendering your bevy app to the terminal using ratatui.

0.14 brings depth detection! Ratatui cameras can now record depth values for each character they draw, and skip drawing characters when something has already been drawn closer to the camera. This depth info can be passed to custom ratatui widgets as well, which lets you use normal ratatui widgets for things like signs, HP bars, or name tags that are supposed to exist in the game world, and that you still need properly covered by objects closer to the camera.

GitHub

bevy_bundled_observers

crate_release

bevy_bundles_observers provides the observers! macro for setting observers on an entity from within a bundle. It is similar to the children! macro, but for observers!

fn coin() -> impl Bundle {
    (
        Name::new("Coin"),
        observers![|_: Trigger<OnCollect>| {
            info!("You collected a coin!");
        }],
    )
}
crates.io

bevy_input_prompts 0.2

crate_release

Mappings from bevy input types to popular input prompt asset paths, like kenney's

crates.io
soft_ratatui

soft_ratatui

crate_release

soft_ratatui — a pure software renderer for ratatui, with no terminal or GPU required. It’s faster than running ratatui in a terminal and supports full Unicode via cosmic-text.

GitHub

bevy_gltf_animation 0.1

crate_release

bevy_gltf_animation automates building AnimationGraphs for simple glTF animation use cases. It also introduces new types like GltfAnimations intending to make it easier to play those animations.

GitHub
bevy_firework

bevy_firework 0.7

crate_release

bevy_firework is a CPU-driven, batch-rendered particle system for the Bevy game engine.

GitHub
bevy_animation_graphbevy_animation_graph

bevy_animation_graph 0.7

crate_release

bevy_animation_graph works as a replacement to most of bevy_animation, and aims to provide a complete animation system and development workflow including animation graphs, animation state machines (i.e. animation controllers) and a graphical editor to create your animation graphs and state machines.

0.7 brings

  • Event-track based animation synchronization: Decorate animation clips with arbitrary event tracks that get sampled in the animation graph as EventQueues. Use those event tracks as synchronization tracks in blend nodes.
  • Node creation popup: You can now click anywhere in the graph editor canvas to bring up a node creation popup.
  • Animation retargeting: You can now do some (very basic) animation retargeting by configuring bone path segments to override in animated scene files.

bevy_pathfinding

bevy_pathfinding

crate_release

bevy_pathfinding features a flowfield + boid approach to pathfinding, as well as spatial partitioning logic for optimization. Great for RTS games! The debug UI can be used to easily view and update the behavior of the system.

crates.io

bevy_link_window_to_monitor

crate_release

bevy_link_window_to_monitor uses Bevy 0.16's relationships to provide a link between Windows and Monitors. So now, getting what Monitor a Window is on is as easy as querying for OnMonitor.
