2024-11-18
This week in Bevy we see Jarl start playtesting, further progress on Polder's building mechanics, and more.
We also see the release of some interesting new particle features in Hanabi, including mesh particles and improve trails.
The CLI working group has also produced the first release of a Bevy linter, which is possibly a great addition for sharing patterns and optimizations for the community.
2024-11-11
The release candidate process continues, which means more stabilization PRs and small bug fixes this week for the most part.
wgpu 23 was released and is now merged for Bevy 0.15. Animation Blending had some blending weight changes to make the blending more reasonable to reason about.
In the community showcase this week there's multiple inverse-kinematic spiders, the holiday season is starting to rear its head, and a really interesting Vulkan backend for Bevy that I'm hoping to see more of in the future.
2024-11-04
Bevy's 0.15 release candidate process is well under way, which means fewer major features making it in as the release candidates stabilize and the official release gets closer.
In the meantime we've got grappling hooks, marching cubes implementations, and game jam games to cover.
We also see the alpha period start for Untold Dawn, a roleplay required text-based multiplayer game.
2024-10-28
The major feature of the issue this week is the start of Bevy 0.15's release candidate process! You can find the current rc on docs.rs and if you're getting ahead of the game you'll find up to date examples for 0.15 in the examples folder in the release-0.15 branch.
Note there is a draft migration guide for early adopters of the release candidates available on the bevy website and if you want more immediate notifications when release candidates go out, take the Notify-RC role in the Bevy Discord.
Feature PRs are a bit lighter this week, as you would expect with 0.15's release candidate process running.
2024-10-21
The first release candidate gets closer this week as it seems like the Required Components migrations are nearing their completion and various bug fixes have made their way in.
The 0.15 milestone can be viewed on GitHub and includes work like an upgrade to wgpu 23 some of which will happen over the course of the release candidates.
In the meantime we've got plenty of PRs to cover and community showcases to explore.
2024-10-14
According to my notes there were over 100 PRs merged last week which represents a truly incredible effort by the community to get ready for the 0.15 release candidates.
0.15 is really shaping up to be a stellar release including Required Components, new Animation and Curve APIs, and more.
There's a whole lot to get into this week so let's start with some new rendering functionality.
2024-10-07
The state of Animation is looking great as we near a potential 0.15 release candidate: with additive blending landing and more PRs in the works.
This week we also see updates on a number of Bevy games in the ecosystem, a whole host of Required Components upgrades are happening, and more.
Let's start off with something that takes a bit more explanation.
2024-09-30
The Bevy Spooky Jam is an unofficial Bevy game jam for the spooky season! It starts on October 4th and runs until October 21st. Bevy Spooky Jam is a casual game jam that the creator would like to turn into a monthly game jam if there's enough interest.
We also see a number of game-boy game jam submissions this week and a release of a new navigation mesh crate.
The Bevy Foundation is now a 501(c)(3) Public Charity!
2024-09-23
Welcome back to another week in Bevy!
This week we see some much needed documentation added to Assets v2, the base of generalized animations, and the ability to turn anti-aliasing on and off.
On top of that there's a new compute-shader based asteroid generator, a fragment shader-based raytracing example, and updates on a couple of games.
2024-09-16
Back from Rust Conf its time to catch up on another week in Bevy!
A Bevy meetup happened in-person at Rust Conf featuring Tiny Glade demos and a Q&A session from Alice, and there was a Bevy talk “Shooting Stars! Livecode a Game in 30 Minutes” presented at the conference. Videos will go out sometime in the future.
The community also responded to Bevy's 4th birthday post this week. The posts were collected in the Community Reflection on Bevy's Fourth Year post on the Bevy blog including Alice's Dream Job post and more from the community.
2024-09-09
0.14.2 is out! Including fixed for UI elements, gizmos, hue mixing, and more. See the full list over on GitHub.
Animations also get a boost this week with Animation Masks, a major part of a highly desired feature. We also see progress in the curves and picking working groups as well as some 0.14.2 UI fixes! And while we won't cover performance this week in depth, don't forget about #14673 which opportunistically used dense iteration for a 3.5x speedup in hybrid parallel iteration.
There are a number of compute shader showcases this week, including shallow water, particle life, and Nannou's new compute abstractions.
2024-09-02
Welcome back to This Week in Bevy!
This week we've got some great progress on Scenes/UI work with Required Components merging, a new Bevy CLI working group, and some great progress in the Curves group.
We've also got some exciting crate releases including an official bevy_magic_light_2d crates.io release and a new Avian Pickup plugin for portal-like shenanigans.
2024-08-26
This week we see some Bevy entries for the 2024 GMTK Jam, an inverse kinematic spider, and asset-driven shaders.
There are a number of different conversations happening at any given time and this week is no different, seeing some interesting WGSL thoughts and experiments in progress as well as more conversation around FixedTimestep usage.
There was also some great conversation this week in #engine-dev around Bevy's target audience, feature set, RFC and working group processes, and more.
2024-08-19
A PR for an implementation of Required Components went up this week. If you have crates that will be affected and are interested in the ongoing Next Generation Scene/UI work then this is an important PR to check out.
This week we see a number of quality-of-life improvements as well as great new lands like custom cursors. Other work merged this week feels like groundswell work than will make for a great 0.15 release.
We also see some interesting crates this week such as bevy_transform_interpolation which aid the use of FixedTimesteps as well as some crates that slipped from last week's issue like leafwing-input-manger 0.15.
2024-08-12
This week we have multiple vello-related projects, some great working group progress, gizmos are seeing more usage, and more.
Bevy Jam 5 voting is finishing up within the next 24 hours. Congrats to all who participated.
Bevy's 4th Birthday happened this weekend with a great post from @cart (Bevy's creator and Project Lead). The post includes a great overview of the last year as well as a call for the community to write their own "Bevy Birthday post" and publish it. One month from now, a followup "Reflecting on Bevy's Fourth Year" rollup post will aggregate these in one place.
2024-08-05
0.14.1 is out, Bevy Jam 5 voting is ongoing for another week, and there's plenty of submissions to showcase this week.
track_change_detection is probably my favorite merged feature this week alongside some new quality-of-life APIs, and a fantastic new example for mid-level rendering APIs. I'm a huge fan of new rendering examples because even when Bevy's rendering changes, the examples are always kept up to date as a solid resource.
We see a bunch of game jam submissions showcase'd this week. They will be mentioned in the issue if the author's chose to showcase their work but we won't be covering games in depth until after voting has closed.
2024-07-29
Much of the ecosystem this week has been taking time to participate in the Bevy game jam in one way or another. By the time you're reading or watching this, Bevy Jam 5 will have closed for submissions and voting will have started. So go play some of the submissions and vote for a winner!
The Next Generation Scene/UI working group is kicking off with an almost 8k word proposal and a suitably large ensuing discussion. The overall proposal intends proposes to
Embrace the "Bevy data model" for both Scenes and UI. Fill in functionality and UX gaps where necessary.
2024-07-22
Bevy Jam 5 is underway! If you haven't joined in yet you still have a whole week so head on over to Itch.io and join the jam.
We've got a whole bunch to cover this week including some exciting crate releases that, if you ask me, were motivated by Bevy Jam 5, and a number of full open source games and releases.
We'll start off as usual covering some project ongoings and merges before getting deeper into the ecosystem and even seeing a 3D editor for Mario Kart Wii tracks.
2024-07-15
This week in Bevy we've got people making use of Observers and Hooks, first games, procedural generation and animation, and more.
The #rendering channel has been talking about technology like MaterialX. We'll see number of different UI showcases including bevy_ui, text-to-speech, and Quill. While other people are implementing papers and talks including destructible stress environment systems and water simulation.
Bevy game jam 5 theme voting is underway. You can sign up to participate here on Itch.io, vote on themes in the #jam-theme-voting Discord channel, and find a team to participate with in #jam-find-a-team.
2024-07-08
The release candidate process has completed for the first time and Bevy 0.14 is available now on crates.io. You can check out the official release post and migration guide.
Many, many crates have already been updated so check your dependencies. For the crates section this week we'll be omitting crates whose changelog is mostly "updated to 0.14".
If you're working on upgrading and find yourself in a situation where you have multiple major versions of Bevy installed, you can run this command to figure out why and what crates still need to be bumped:
2024-07-01
The release-candidate process continues as 0.14.0-rc.4 went out this week. Changes between rc.3 and rc.4 can be viewed on GitHub.
It looks like the stable release will happen this week, but to be clear there is no date set and the release will happen when it is ready and the release candidate process has run its course.
If you've been using the 0.14 release candidates, you might notice some changes to the inclusion of BackgroundColor in bundles such as the ImageBundle in the most recent release candidate. 14017 adds them back in for DX aims where they were removed before.
2024-06-24
As we get closer to the stable release of a lot of the ecosystem efforts are going into stabilizing and preparing crates. This is the first time we've had a release candidate cycle for Bevy so it will be interesting to see how that impacts the final release.
So far the release candidate process has been well regarded overall, resulting in bugs being found and time for third party crates to upgrade before the day of the release.
Similar to previous issues, more crates have been updated to be compatible with the release-candidate which is currently rc.3, but we don't mention them individually here. Check the releases and GitHub repos for your dependencies for updates.
2024-06-17
Release Candidate 0.14.0-rc.3 is out this week with one last new feature for 0.14 (Observers), an upgrade to wgpu 0.20 (previously 0.19), as well as assorted fixes for rc.2.
With the 0.14 release getting closer fewer major features are getting merged but we still have some great functionality to talk about.
As always you can keep up to date with the release using the 0.14 milestone.
2024-06-10
For the 0.14 release cycle, Bevy is shipping a release candidate before the official release. As such, the 0.14.0-rc.2 release candidate is available now and some crates are already starting to ship 0.14-rc compatible versions.
You can check in on the Bevy 0.14 milestone if you're running into any issues with the release candidate.
In the showcases this week, we'll see a Bevy "Powerglove", Inkscape level editing, new global illumination projects, and more.
2024-06-03
This week in the Bevy ecosystem we see Tiny Glade ship a Steam demo, live VJ sets powered by Bevy, screen space reflections in the deferred renderer and more.
We've also got the usual showcases and a couple really interesting crate release for 2d lighting systems and gpu particles.
Tiny Glade's Demo is out this week with the ability to build small castles and yes, you can pet the sheep. Tiny Glade uses Bevy's ECS and their own custom renderer, which they talk about a bit in this 80 level article.
2024-05-27
This week in Bevy the ecosystem is going strong as the 0.14 release creeps closer.
The fourth unofficial Bevy meetup was livestreamed on May 24th including 3 talks.
RenderPipelines titled Hooking into the Bevy Rendering Pipeline. It came with a wonderful GitHub repo with working code.2024-05-20
Bevy 0.14's release cycle is just getting started with the creation of the 0.14 release crew working group (discord link to working group). Alice talked a bit about the creation of the group and what its trying to do over on Mastodon).
There is now a milestone for the release that Alice covered in depth, so check it out if you're interested in what's left to do for 0.14.
In the meantime, here's what else has been happening this week.
2024-05-13
This week in Bevy there are a bunch of new examples added to the repo, new additions to the StandardMaterial, and more.
Out in the wider ecosystem, we'll see 400,000 entities on a flowfield in the showcases as well as crates for networking, ui, and signals.
On top of that there are game updates from past Bevy jams, card games and more.
2024-05-06
This week in Bevy we've got some project changes relating to contributing, PR review, and the formalization of working groups, new color grading and state-management features, as well as some exciting experiments and demos.
Particularly interesting on the experimental side of things is a new crate and some experimentation with Bevy/Vello integration.
Additionally I'd like to call out the VisibilityRanges, Filmic color grading, and GPU Frustum Culling PRs as being particularly well-commented with straightforward PR descriptions. They serve as great entry points into reading about their respective topics in the Bevy context.
2024-04-29
This week in Bevy we've got new Motion Blur bundles, a few interesting new examples, and some great looking games and visualizations.
Especially exciting this week is that the Bevy Foundation has reached an exciting milestone in enabling Alice to start full-time on May 1st. This is not the end of the road in funding, rather it is the beginning of the beginning of the short-term plans outlined in the Foundation announcement and is a good sign for the beginning of what I hope is a substantial future for Bevy, in my opinion.
If you want to see Bevy succeed, like I do, and can afford to: You can donate to Bevy today.
2024-04-22
A whole host of exciting developments this week including a bunch of Ludum Dare entries, progress on Nannou's Bevy rewrite, and Bevy running on an ESP32 microcontroller.
There are a bunch of games written in Bevy that were submitted to Ludum Dare 55. Game jams are always a great show so we cover those that promoted their games in the showcases this week.
Nannou, the Rust creative-coding framework is making great progress on their Bevy plugin rework. We dive into some of the recent work in the relevant showcase later in this issue.
2024-04-15
This week in Bevy we've got some new meshes, new gizmos, and a couple of great new examples in the Bevy repo.
We've also got the first of the ludum dare participants showing off what they've been working on and some really deep dives in the educational section.
bevy_utils has a tracking issue to either remove or reduce the crate. #12772 makes progress towards this goal. The overarching effort here is largely refactoring and moving code, so can be a great introduction to the codebase for newer contributors.
2024-04-08
Bevy 0.13.2 is out with some bugfixes for the 0.13 release cycle. The full milestone is available on GitHub.
bevy_math got a new Tetrahedron primitive and the Annulus added last week got its meshing implemetation which means it can be added to the 2d shapes example.
The close_on_esc system, which is a helper utility Bevy offers to allow closing the application when Escape is pressed, was moved into the growing set of features in bevy_dev_tools.
2024-04-01
Welcome to another week in the Bevy ecosystem!
This week we've got a number of 2d lighting examples, deep dives into GPU particles and bevy_ecs, as well as dialogue systems, and some exciting new Bevy merges.
Have you ever had trouble reading type errors? Argus is a trait debugger for Rust that was released this week, with first-class VSCode integration. Give it a try and see if it helps you identify system errors in your next Bevy App.
2024-03-25
Dev tools can be more than a grab bag of "things that developers find useful": there are real commonalities and patterns!
— Alice
Bevy 0.13.1 is out now with fixes for globals in vertex shaders, and more.
I'm in London this week to give a talk on Bevy at RustNation UK. My talk centers on the Rusty ergonomics that Bevy applies to empower people to build games, so when I saw RFC 77 - dev-tools-abstraction I knew I had to read it.
2024-03-18
Welcome to another week in the Bevy ecosystem!
This week the Bevy Foundation was announced and several talks were given at the second unofficial Bevy Meetup.
If you're interested in some of the deeper magic, bevy_ptr got some great new docs this week and the computational complexity of different input detection methods is now documented. bevy_dev_tools started getting code filled in with the FpsOverlayPlugin and Gizmos also grew with the addition of 3d grids and line joints.
2024-03-11
Welcome to another week in the Bevy ecosystem!
This week we've got some new work on animation graphs, a lot of Bevy Cheatbook updates, and a new bevy_dev_tools crate.
A few new crates have also been published, including an interesting path recording crate.
2024-03-04
Welcome to another week in the Bevy ecosystem!
This week we've got the new bevy_color crate, a few new gizmos, and a number of people started participating in the 7 day roguelike challenge game jam.
We also cover some updates to the Lighting system that happened in 0.13 and how you might want to update your app.
