nested lists, long titles, images with important small details, - code blocks with long lines, etc. - -- Don't use fourth-level headers. - Divide a section into subsections using a `------` line if needed. - -- Avoid using bold, italic, etc rich formatting if possible. - -- Write from a third-person perspective even if you're writing - about your project's updates. - -- Use singular "they" if you're not sure what the person's pronouns are. - -- If the project was already featured in the newsletter, - use a one-sentence description at the beginning of the section - as a reminder for readers - and describe only the updates next. - -- It's ok to add a donation/sponsorship link, -

otherwise please check the results of the CI run. - -- Insert line breaks ([softbreak]) at 80 chars. - -- Use [reference-style links][md-reflinks] and group them into blocks - at the end of the (sub)sections. -

New submissions go into the next + month's newsletter. +- 3rd of the next month: The newsletter is published. Any submissions not edited +in time will be moved to the next month or removed entirely. + +This more strict schedule should help with the issue of late entries and reduce +the pressure of editing by having a dedicated time for it with no incoming +submissions. The goal is to be more consistent and reliable in our publishing +schedule. + +### Community Survey + +This restructuring is also a good time to improve the content of the newsletter. +We've got some community feedback on the [Rust GameDev Discord][Discord] already +and would like to hear more from you.

We will be evaluating +the [survey] results in an upcoming blog post, so stay tuned for that. + +### Future Steps + +Based on feedback we've already gotten, the steps for next months are: + +- Add an email subscription option to the newsletter +- Setup a system for how to edit entries that are not ready before the +newsletter ships. We are currently looking into either hiring a part-time +editor, using generative AI to add a few sentences where needed, or simply +removing these entries. + +That's all for now.

Thank you very much! + +The biggest takeaways are: +- People are generally excited about the newsletter +- The current frequency of the newsletter is good +- Readers do not want anything in the newsletter generated by AI +- Contributing to the newsletter could be easier. If you've got ideas on how to make this happen, please [let us know](https://github.com/rust-gamedev/rust-gamedev.github.io/issues/1519)! + +We will now go through the results in the same order as the questions were asked. The full analysis and data is open-sourced on [GitHub](https://github.com/janhohenheim/rust-gamedev-statistics/tree/main/jan-hohenheim-2024). + +## Excitement + +![Excitement barplot](excitement.png) + +On average, readers are excited about the newsletter. The mean excitement level is 3.6 out of 5, the median is 4. +Our 95% confidence interval is [3.32, 3.91] using a standard error of 0.15 (sd = 1.05, n = 52). + +These are fairly nice results. Anecdotally, we got a lot of messages about issues with the newsletter and how to improve it, +so we are happy to see that the excitement is still high. Still, the data shows that we have room for improvement. + +## Content Quantity + +![Content quantity barplot](content_quantity.png) + + +When asked about how to change the amount of content per newsletter, the majority of readers (58%) voted to leave the amount as-is or don't care. +On the other hand, this means nearly half of the readers would change something about the content quantity. +17% voted for "less content; keep only the most important news" and 25% for "more content; add sections for minor news". +These two options are luckily not mutually exclusive. +One option we could implement is to have a new section for "minor news" where we don't go into detail, +and a section for "miscellaneous links" where we only list some links without any commentary. + +## Newsletter Frequency + +![Newsletter frequency barplot](frequency.png) + +73% of readers are either happy with the current frequency or don't care. A minority of 21% would like the newsletter to become quarterly. +Arguments we've heard for this are that a lower frequency would allow editors to improve the quality that goes into each newsletter. +Counterarguments include that a lower frequency would make the newsletter less timely. +Things like calls for playtesters or job offers would be less useful if they were only sent out every three months. + +## AI + +![AI barplot](ai.png) + +This question was a catalyst for a lot of discussion on [Discord]. + +If we interpret the answers as a scale of 1-5, where 1 is "not okay at all" and 5 is "I love it", the mean answer was 2.25, the median 2. +Notably, the mode is tied at 1 and 2. The 95% confidence interval is [1.89, 2.61] using a standard error of 0.18 (sd = 1.30, n = 52). +People are generally against using an LLM to generate summaries. 79.2% of readers would prefer not to use AI. + +Viewed from another angle: while a majority of readers (65%) are at least okay with AI-generated summaries, +a significant minority (35%) are not okay at all with this proposal. +These include very active members of the community and +contributors who have announced that they would no longer want their content to be included in the newsletter if AI was used. + +The reasons people gave for not wanting AI-generated summaries were varied. +Among these were: +- Solidarity with the large number of creatives who recently lost their jobs due to AI-generated content, +inside and outside the game development industry. +- Concerns about the quality of AI-generated summaries. +- Skepticism about AI-generated summaries saving time if they still need to be edited by hand. + +## Tone + +![Tone barplot](tone.png) + +A significant majority of readers (86.5%) are happy with the current tone of the newsletter, with a minority of 11.5% wanting a less formal tone. +While votes for the latter did not reach a majority, the written feedback we got included quite a few requests for more "personality" in the newsletter. + +## Contributions + +![Contributions barplot](contributions.png) + +The majority of readers (61.5%) have not yet contributed to the newsletter and 26.9% have contributed 2-5 times. +Only 3.8% contributed exactly once, while the rest (7.7%) are heavy contributors, helping us out more than five times. + +While it might seem weird that more people contributed 2-5 times than exactly once, +keep in mind that the former is the sum of people who contributed twice, thrice, four times, and five times. +The reason we binned these together is that we are interested in the following categories: +- Pure readers +- People who contributed once and then stopped +- People who contributed a few times +- People who are regular contributors + +We are happy to see that people who contributed once seem to continue contributing in the future. + +## Ease + +![Ease barplot](ease.png) + +The mean ease of contributing is 3.0, and the median is 3. The 95% confidence interval is [2.5, 3.6] using a standard error of 0.26 (sd = 1.26, n = 23). + +Readers generally feel neutral about the ease of contributing to the newsletter. + +We can do better here, but we are not sure yet how. +We'd love to hear your ideas on [GitHub](https://github.com/rust-gamedev/rust-gamedev.github.io/issues/1519) or on [Discord] (ping @janhohenheim). + +## Keeping up with the newsletter + +![Keeping up barplot](informed.png) + +This was a multiple-choice question. The most popular source of information about the newsletter is RSS (27.5%). +If we add the choices for the official [Rust GameDev Discord server][Discord] (21.7%) and other Discord servers (11.6%), +Discord in general becomes the leading source of information (33.3%), taking up nearly exactly a third of all votes. + +We can see the shift from X / Twitter to Mastodon reported by many OSS communities in our readers as well. +Lemmy is not looking popular as an alternative to Reddit yet, with no reader reporting it as a source of information. + +The "Email" option in the survey is meant for people who have set up some kind of email alerts manually. + +Per written feedback, a lot of people want to see proper email subscriptions implemented. While this was a goal for this month, +we have not managed to implement it yet. +We will try to [get this done](https://github.com/rust-gamedev/rust-gamedev.github.io/issues/24) for the next newsletter. + +## What is going well + +![What is going well wordcloud](like.png) + +This was a free-text question. The above is a word cloud of the answers with some obvious words like "game" or "newsletter" removed. +Note that the inclusion of the word "AI" is misleading, as it was only mentioned in answers that read similar to +"I like that we don't use AI, please don't use LLMs". + +Going through the feedback by hand, common things readers enjoy about the newsletter are: +- A good mix of content +- Very open to contributions +- Small-scale games are featured, not just success stories or technical articles + +## What needs to be improved + +![What needs to be improved wordcloud](improve.png) + +Another free-text question. The feedback here is fairly diverse. The most common complaints we already mentioned in previous sections are: +- Add an email subscription +- Improve the ease of contributing + +Additionally, many people feel like the "Games" section reads more like an advertisement than an article aimed at other game developers. + +Among the more unique suggestions were: +- Conduct interviews +- Have a stronger sense of personality in the writing +- Make the newsletter more consistent in timing and quantity +- Have more editors to not overburden the current ones +- Have some more clarity of purpose + + +## Comments + +![Comments wordcloud](comment.png) + +This last free-text question was meant for any additional comments readers might have. +The word cloud above is dominated by one sentence: "Thank you for your work". Thank you very very much for your kind words! +We are working on this newsletter in our free time because we love the community and Rust game development, so reading this means a lot to us. + +## Correlations + +We were interested in how the responses to some questions correlated with how much people had already contributed to the newsletter. +Long story short: it seems like there is no significant correlation between how much people contributed and how they answered the other questions. + +Let's look at the correlations in turn now. +Note that all the following plots are jittered to make the data more readable. + + +### Excitement By Contributions + +![Excitement correlation](excitement_contributions.png) + +We hypothesized that people who contributed more to the newsletter would be more excited about it. +We found no evidence for this (the p-value of a Jonckheere-Terpstra test for increasing trend is 0.986). +Based on the plot above, we then hypothesized that the opposite might be true, namely that frequent contributors are less excited about the newsletter. +This actually might be the case (p-value is 0.021), but do not take this as a strong result. +It is a posthoc hypothesis and the resulting p-value is not very low considering the number of tests we run in this analysis. +For these reasons, we do not consider this result to be significant. + +### Feelings About AI By Contributions + +![AI correlation](ai_contributions.png) + +We hypothesized that there would be a correlation between how much people contributed to the newsletter and how they felt about AI-generated summaries. +We found no evidence for this (the p-value of a Jonckheere-Terpstra test for a two-sided alternative is 0.57). + +### Ease of Contributing By Contributions + +![Ease correlation](ease_contributions.png) + +We hypothesized that there would be a correlation between how much people contributed to the newsletter and how easily they found it to contribute. + +We found no evidence for this (the p-value of a Jonckheere-Terpstra test for a two-sided alternative is 0.25). + +## Conclusion + +All in all, we are happy with the results of the survey. +It seems like our readers are generally happy with the newsletter, and have good ideas on how to improve it. +We will discuss how to implement these ideas in the future and keep you updated on our progress. + +If you are interested in helping us out, we are always looking for new editors and contributors. Just leave us a message on [Discord] or [GitHub]. + +Again, thank you very much for your feedback. Rebooting the newsletter was a big ordeal for us, +and we are happy to see such an active interest in the community. We hope that we can continue to provide you with a newsletter you enjoy. + +Until next time! + +~ The Rust GameDev Newsletter Team, and Jan Hohenheim in particular + +[Discord]:

Traditional techniques +account for network transmission time by delaying the game execution, resulting +in a sluggish game-feel. Rollback uses input prediction and speculative +execution instead. Upon receiving inputs from remote clients, resimulation of +incorrect game states occurs. This allows for gameplay that "feels just +like offline". The open source standard for rollback netcode [GGPO] is used +in successful games like Skullgirls, Guilty Gear XX Accent Core +R or +Fightcade. For further explanation about rollback, +[click here](https://ki.infil.net/w02-netcode.html). + +Two projects in Rust were independently created to provide a working +implementation as well as helpful resources for developers. +backroll-rs features an added abstraction for the transportation layer and +also provides a bevy plugin, [bevy-backroll]. GGRS replaces the +C-style callback API of GGPO with a simpler, more understandable control flow. +The authors of both libraries recommend backroll-rs for development, +as it is currently more actively collaborated on. +GGRS is recommended as a learning resource and entry point, +with a plethora of internal documentation and explanation. + +The main requirement to make use of both presented libraries is determinism +in your game execution. Resimulation requires that the result of progressing +the game state depending on the given inputs yield the exact same results +every time. Additionally, you need to be able to load, save and progress +your gamestate without rendering the outcome. + +If you are interested in integrating rollback networking into your game or +just want to chat with other rollback developers (not limited to Rust), +check out the [GGPO Developers Discord]! + +[backroll-rs]: https://github.com/HouraiTeahouse/backroll-rs +[bevy-backroll]: https://github.com/HouraiTeahouse/backroll-rs/tree/main/bevy_backroll +[GGPO Developers Discord]: https://discord.gg/8FKKhCRCCE +[GGRS]: https://github.com/gschup/ggrs +[GGPO]: https://www.ggpo.net/ +[@g_schup]: https://twitter.com/g_schup +[@james7132]: https://twitter.com/james7132 + +### [CrystalOrb] + +{{ image_figure( + alt="CrystalOrb demo animation" + src="crystalorb.gif" + caption="Interactive [demo](https://ernestwong.nz/crystalorb/demo) that uses the [Rapier](https://rapier.rs) physics engine.", + link="https://ernestwong.nz/crystalorb/demo") }} + +[CrystalOrb] by [@ErnWong] is a new networking library that aims to help +fast-paced client-server games synchronize their game state across multiple +clients. Just like [backroll-rs] and [GGRS], each CrystalOrb client predicts +the next game state without waiting for other remote players' inputs to arrive. +Unlike backroll-rs's and GGRS's peer-to-peer approach which only send input +data between its peers, CrystalOrb relies on having a server to send +authoritative snapshots of the entire game state to each client. In response, +each client unconditionally rolls-back to that snapshot. Although this may lead +to higher network and memory usage, it means that CrystalOrb clients can join +and leave at any time, and games that cannot guarantee full-determinism can +still work with CrystalOrb. + +This library was written as a learning exercise for the author, and as such, +the author warns that this library may not be suitable for serious games. + +There is an [interactive demo][crystalorb-demo] of CrystalOrb that features the +[Rapier] physics engine. + +[CrystalOrb]: https://github.com/ErnWong/crystalorb +[@ErnWong]: https://github.com/ErnWong +[crystalorb-demo]: https://ernestwong.nz/crystalorb/demo +[backroll-rs]: https://github.com/HouraiTeahouse/backroll-rs +[GGRS]: https://github.com/gschup/ggrs +[Rapier]: https://rapier.rs + +### [glutin] (and [winit]) + +{{ image_figure( + alt="Animated image showing a window that is opened with a spinning cursor on top" + src="winit-bug-1.gif" + caption="This cursor may be waiting [in vain], but your patience shall be rewarded.") }} + +[glutin] is a low-level library for OpenGL context creation, written in pure Rust. +[glutin] uses and re-exports [winit], which handles window creation and management, +as well as various input devices. + +This month, glutin 0.27.0 was released, which makes glutin use the latest version +of winit (0.25.0), which was released around a month prior to glutin 0.27.0.

You have to create a `VkInstance`, with the validation layers +set up and working for development. Then select the best suited +`VkPhysicalDevice` for your app's requirements. Use that to create a `VkDevice` +with the appropriate queue families chosen. Oh, and after that, you need +to struggle with managing and resizing a Vulkan swapchain. + +That's no fun — and this is where [erupt-bootstrap] comes in.

Work is being done to prepare for the 0.13 release, with a custom +map being built, and a special treasure map being created for the launch party. +Player bank storages are being developed, which will allow players to store +excess items in towns. + +April's full weekly devlogs: "This Week In Veloren...": +[#166][veloren-166], +[#167][veloren-167], +[#168][veloren-168], +[#169][veloren-169]. + +[veloren]: https://veloren.net + +[veloren-cart]: https://veloren.net/veloren-direction/ +[veloren-finances]: https://veloren.net/devblog-167#finances-by-angelonfira +[veloren-reading-club-8]: https://www.youtube.com/watch?v=ff9EXhCXmFY +[veloren-code-review-2]: https://www.youtube.com/watch?v=keI0VpjkgZg + +[veloren-166]: https://veloren.net/devblog-166 +[veloren-167]: https://veloren.net/devblog-167 +[veloren-168]: https://veloren.net/devblog-168 +[veloren-169]: https://veloren.net/devblog-169 + +### Oasis of Lost Hope + +![Oasis of Lost Hope](oasis-of-lost-hope.jpg) + +Oasis of Lost Hope is a game where fertile ground is steadily consumed by dark, +barren land called blight. Water helps defend an area from being consumed, but +reserves are finite. The player needs to collect ore to build more irrigation +towers and delay doom for a few more seconds. Yet one thing is certain: the days +of fertile land are counted. + +The game is an entry for the Ludum Dare 50 Jam, the theme of which was "Delay +the Inevitable". It has been developed by setzer22 and Bromeon and [open-sourced +on GitHub][oasis-gh]. The game is built on top of godot-rust alongside GDScript. +The Rust language is not exactly known for fast prototyping, but with a slightly +less safety-conservative fork of godot-rust, the game jam experience was +surprisingly smooth.

Level of +detail objects were added, so trees can now be seen on far-off mountains. This +makes the world feel significantly more alive. A lot of work was done on the +performance of the game server, as Veloren has been seeing over 100 concurrent +players at peak on the server nearly every day for the past few weeks. + +Lots of work was done on balancing items and drop rates. Water caves have been +worked on, which now means that you might need to enter them from underwater. +Modular weapons were merged, which was a change several months in the making. +NPCs are now able to pick up items that are on the ground. Work was done on +taming and mounting various animals. Weather is still in the works, with +improvements to the ambient SFX system for rain.

While the +current 0.1.1 release is not very configurable yet, the idea is to make the +crate more malleable working towards a 0.2.0 release so that it will support +a range of grids (4-connected, 8-connected, weighted, etc.) as well as +heuristics. Specifically, [grid_pathfinding] 0.1 assumes a uniform-cost +8-grid with a Chebyshev cost metric and heuristic. More long-term goals are +support for multi-tile and multi-agent pathfinding variants. + +The current implementation is based on [Jump Point Search] with +[improved pruning rules]. On top of this, [connected components] are used to +avoid flood-filling behaviour if no path exists - see the +[documentation][gp-docs] and [examples][gp-examples] for information on +how to manage these components.

The crate was +rewritten from scratch and redesigned around [raw-window-handle], so +you don't need [winit] anymore in this equation and it could be used with +whatever windowing library you prefer, like [smithay-client-toolkit] for +pure Wayland clients. + +Given everything is based on raw-window-handle the crate is more low-level +now and also exposes the underlying platform API like `EGL`, `GLX`, and `WGL` +directly. There's already an interest of using glutin to handle `EGL` in +projects like [Smithay]. + +Previously with glutin `0.29` everything was based around the single +[`WindowedContext`] - while this was convinient for some users and worked on +desktop platforms, that fact was a major pain on Android where the window +gets destroyed over time, but its context could be kept around, or when you +fail to query configuration with supplied parameters leading to chain creating +`WindowedContext` and causing delays on startup. For example, you can create all +the objects and then fail on setting vsync, forcing you to start over. + +None of that is an issue with glutin `0.30.0`. The API is now structured around +`Display`, `Context`, `Surface`, and `Config`, where every object is built from +the `Display` and has its own role which is close to what you usually can find +in OpenGL native rendering platforms specifications, like `EGL`. + +Unfortunatelly, the new API isn't as easy to bootstrap as it was with old +glutin, especially when you want to use platforms like `WGL` and `GLX`. +However, if you're using winit there will be (or is already) a special crate +[glutin-winit] to handle platform-specific `Display` creation for you. + +To see the new API in action, look at the [glutin examples]. They +should work on desktop platforms and Android (you may even notice that there's +no special code for Android at all!). + +One note to add, is that iOS is **no longer** supported, but only due to +lack of maintainers for it. If you rely on iOS support in glutin, the devs +encourage you to help contributing to it upstream, or you'd stuck with glutin +`0.29` which won't receive any updates anymore. + +For further info, check out the [winit matrix room](https://matrix.to/#/#winit:matrix.org) +or [#winit](https://web.libera.chat/#winit) at libera.chat. + +[glutin]: https://crates.io/crates/glutin +[glutin examples]: https://github.com/rust-windowing/glutin/tree/master/glutin_examples +[glutin-winit]: https://github.com/rust-windowing/glutin/pull/1517 +[winit]: https://crates.io/crates/winit +[Smithay]: https://github.com/smithay/smithay +[`WindowedContext`]: https://docs.rs/glutin/0.29.1/glutin/type.WindowedContext.html +[smithay-client-toolkit]: https://crates.io/crates/smithay-client-toolkit +[glutin-github]: https://github.com/rust-windowing/glutin +[raw-window-handle]: https://crates.io/crates/raw-window-handle +[glutin-docs]: https://docs.rs/glutin +[@kchibisov]: https://github.com/kchibisov +[rust-windowing]: https://github.com/rust-windowing + +### [presser] + +[presser] ([GitHub][presser-github], [docs.rs][presser-docs]) +by [@fu5ha] ([Embark Studios][embark]) +is a crate to help you copy things into raw buffers without +invoking spooky action at a distance (undefined behavior). + +Ever done something like this? + +```rust +#[derive(Clone, Copy)] +#[repr(C)] +struct MyDataStruct { + a: u8, + b: u32, +} + +let my_data = MyDataStruct { a: 0, b: 42 }; + +// 🚨 MyDataStruct contains 3 padding bytes after `a`, which are +// uninit, therefore getting a slice that includes them is UB! +let my_data_bytes: &[u8] = transmute(&my_data); + +// allocate an uninit buffer of some size +let my_buffer: MyBufferType = some_api.alloc_buffer_size(2048); + +// 🚨 this is UB for the same reason, these bytes are uninit!* +let buffer_as_bytes: &mut [u8] = + slice::from_raw_parts(my_buffer.ptr(), my_buffer.size()); + +// 🚨 this is UB because not only are both slices invalid, +// this is not ensuring proper alignment! +buffer_as_bytes.copy_from_slice(my_data_bytes); +``` + +[presser] can help. + +```rust +// borrow our raw allocation as a presser::Slab, asserting we have +// unique access to it. see the docs for more. +let slab = unsafe { raw_allocation.borrow_as_slab(); } + +// now we may safely copy `my_data` into `my_buffer`, +// starting at a minimum offset of 0 into the buffer +let copy_record = presser::copy_to_offset(&my_data, &mut slab, 0)?; +``` + +If you're not convinced this is actually an issue, read more in the +[crate readme][presser-readme].

What this means is that users can choose a different model +or create their own using the `Atmospheric` trait. This sets the groundwork for +having a variety of models to choose from, each for a different type of game. + +With the removal of the `Atmosphere` resource, comes the addition of the +`AtmosphereModel` resource and the `Nishita` and `Gradient` models. `Nishita` +is the same model that was used in the previous version of bevy_atmosphere. +`Gradient` is a new model that provides a simple gradient of three colors, +making it ideal for stylized games. + +There is also the `Atmosphere` and `AtmosphereMut` system params, +which can be used to work with a particular model +without having to cast it from `AtmosphereModel`. + +If you want to read more about the technical changes, check out the developer's +[blog post](https://jonahplusplus.dev/2022/12/01/bevy_atmosphere_0.5.html)! + +_Discussions: +[/r/rust_gamedev](https://reddit.com/r/rust_gamedev/comments/za948o/bevy_atmosphere_05_is_now_released), +[/r/bevy](https://reddit.com/r/bevy/comments/za93oo/bevy_atmosphere_05_is_now_released), +[/r/rust](https://reddit.com/r/rust/comments/za93zb/bevy_atmosphere_05_is_now_released)_ + +[bevy_atmosphere]: https://crates.io/crates/bevy_atmosphere + +### [Bevy Sequential Actions] + +{{ image_figure( + alt="Bevy sequential actions simple demo" + src="sequential_actions.gif" + caption="An entity with a queue of repeating actions.") }} + +`bevy-sequential-actions` ([GitHub][seq-actions-gh], [docs.rs][seq-actions-docs]) +is a simple helper library for the [Bevy][bevy] game engine. +It aims to execute a queue of various actions in a sequential manner. + +An action is anything that implements the `Action` trait, +and can be added to any `Entity` that contains the `ActionsBundle`. +In the image above, the following actions have been added: + +```rust +commands + .actions(entity) + .config(AddConfig { + order: AddOrder::Back, + start: true, + repeat: Repeat::Forever, + }) + .add(WaitAction::new(1.0)) + .add(MoveAction::new(Vec3::X * 2.0)) + .add(WaitAction::new(1.0)) + .add(MoveAction::new(Vec3::X * -2.0)); +``` + +With version `0.6` comes the ability to +add a collection of actions that run in parallel. +This means that all actions will start and stop at the same time, +as the whole collection is treated as "one action". +In other words, the action queue will only advance +when all actions in the collection are finished. + +```rust +commands + .actions(agent) + .add_many( + ExecutionMode::Parallel, + actions![ + action_a, + action_b, + action_c, + ] + ); +``` + +[Bevy Sequential Actions]: https://crates.io/crates/bevy-sequential-actions +[seq-actions-gh]: https://github.com/hikikones/bevy-sequential-actions +[seq-actions-docs]: https://docs.rs/bevy-sequential-actions + +### [Sparsey] v0.10 + +[Sparsey] by [@LechintanTudor] is an Entity Component System focused on +flexibility, conciseness and providing features exclusive to its sparse +set-based implementation. + +The latest release takes advantage of the newly added Generic Associated Types +to provide a uniform interface for running systems, functions and closures that +borrow data from World and Resources, via the "run", "run_locally" and +"run_exclusive" functions. + +Example: + +```rust +let heaviest = sparsey::run(&world, &resources, |weights: Comp| { + (&weights) + .iter() + .with_entity() + .max_by_key(|(_entity, &weight)| weight) + .map(|(entity, _weight)| entity) +}); +``` + +[Sparsey]: https://github.com/LechintanTudor/sparsey +[@LechintanTudor]: https://github.com/LechintanTudor + +### [Bevy Quickmenu][bevy_quickmenu_crates] + +![Bevy Quickmenu simple menu demo](bevy_quickmenu.gif) + +bevy_quickmenu ([crates.io][bevy_quickmenu_crates], +[docs.rs][bevy_quickmenu_docs], [GitHub][bevy_quickmenu_github]) allows quickly +creating nested game menus that can be navigated with keyboard, gamepad or +mouse. + +Bevy Quickmenu builds on BevyUI and allows defining nested menu structures in a +super simple way.
