# Objective
Fix#12273
## Solution
– Only emit `KeyboardFocusLost` when the keyboard focus is lost
– ignore synthetic key releases too, not just key presses (as they're
already covered by `KeyboardFocusLost`)
---
## Changelog
### Fixed
- Don't trigger `ButtonInput<KeyCode>::just_pressed`/`just_released`
when spawning a window/focus moving between Bevy windows
# Objective
- Fixes#6370
- Closes#6581
## Solution
- Added the following lints to the workspace:
- `std_instead_of_core`
- `std_instead_of_alloc`
- `alloc_instead_of_core`
- Used `cargo +nightly fmt` with [item level use
formatting](https://rust-lang.github.io/rustfmt/?version=v1.6.0&search=#Item%5C%3A)
to split all `use` statements into single items.
- Used `cargo clippy --workspace --all-targets --all-features --fix
--allow-dirty` to _attempt_ to resolve the new linting issues, and
intervened where the lint was unable to resolve the issue automatically
(usually due to needing an `extern crate alloc;` statement in a crate
root).
- Manually removed certain uses of `std` where negative feature gating
prevented `--all-features` from finding the offending uses.
- Used `cargo +nightly fmt` with [crate level use
formatting](https://rust-lang.github.io/rustfmt/?version=v1.6.0&search=#Crate%5C%3A)
to re-merge all `use` statements matching Bevy's previous styling.
- Manually fixed cases where the `fmt` tool could not re-merge `use`
statements due to conditional compilation attributes.
## Testing
- Ran CI locally
## Migration Guide
The MSRV is now 1.81. Please update to this version or higher.
## Notes
- This is a _massive_ change to try and push through, which is why I've
outlined the semi-automatic steps I used to create this PR, in case this
fails and someone else tries again in the future.
- Making this change has no impact on user code, but does mean Bevy
contributors will be warned to use `core` and `alloc` instead of `std`
where possible.
- This lint is a critical first step towards investigating `no_std`
options for Bevy.

# Objective
- Fixes#12639.
- `ReceivedCharacter` was deprecated in #12868 for 0.14, and should be
removed for 0.15.
## Solution
- Remove all instances of `ReceivedCharacter`, including the relevant
`#[allow(deprecated)]` lint attributes.
## Migration Guide
`ReceivedCharacter` was deprecated in 0.14 due to `winit` reworking
their keyboard system. It has now been fully removed. Switch to using
`KeyboardInput` instead.
```rust
// 0.14
fn listen_characters(events: EventReader<ReceivedCharacter>) {
for event in events.read() {
info!("{}", event.char);
}
}
// 0.15
fn listen_characters(events: EventReader<KeyboardInput>) {
for event in events.read() {
// Only check for characters when the key is pressed.
if !event.state.is_pressed() {
continue;
}
// Note that some keys such as `Space` and `Tab` won't be detected as a character.
// Instead, check for them as separate enum variants.
match &event.logical_key {
Key::Character(character) => {
info!("{} pressed.", character);
},
Key::Space => {
info!("Space pressed.");
},
_ => {},
}
}
}
```
# Objective
Correctly order picking events. Resolves
https://github.com/bevyengine/bevy/issues/5984.
## Solution
Event ordering [very long standing
problem](https://github.com/aevyrie/bevy_mod_picking/issues/294) with
mod picking, stemming from two related issues. The first problem was
that `Pointer<T>` events of different types couldn't be ordered, but we
have already gotten around that in the upstream by switching to
observers. Since observers run in the order they are triggered, this
isn't an issue.
The second problem was that the underlying event streams that picking
uses to create it's pointer interaction events *also* lacked ordering,
and the systems that generated the points couldn't interleave events.
This PR fixes that by unifying the event streams and integrating the
various interaction systems.
The concrete changes are as follows:
+ `bevy_winit::WinitEvent` has been moved to `bevy_window::WindowEvent`.
This provides a unified (and more importantly, *ordered*) input stream
for both `bevy_window` and `bevy_input` events.
+ Replaces `InputMove` and `InputPress` with `PointerInput`, a new
unified input event which drives picking and interaction. This event is
built to have drop-in forward compatibility with [winit's upcoming
pointer abstraction](https://github.com/rust-windowing/winit/pull/3876).
I have added code to emulate it using the current winit input
abstractions, but this entire thing will be much more robust when it
lands.
+ Rolls `pointer_events` `send_click_and_drag_events` and
`send_drag_over_events` into a single system, which operates directly on
`PointerEvent` and triggers observers as output.
The PR also improves docs and takes the opportunity to
refactor/streamline the pointer event dispatch logic.
## Status & Testing
This PR is now feature complete and documented. While it is
theoretically possible to add unit tests for the ordering, building the
picking mocking for that will take a little while.
Feedback on the chosen ordering of events is within-scope.
## Migration Guide
For users switching from `bevy_mod_picking` to `bevy_picking`:
+ Instead of adding an `On<T>` component, use `.observe(|trigger:
Trigger<T>|)`. You may now apply multiple handlers to the same entity
using this command.
+ Pointer interaction events now have semi-deterministic ordering which
(more or less) aligns with the order of the raw input stream. Consult
the docs on `bevy_picking::event::pointer_events` for current
information. You may need to adjust your event handling logic
accordingly.
+ `PointerCancel` has been replaced with `Pointer<Cancled>`, which now
has the semantics of an OS touch pointer cancel event.
+ `InputMove` and `InputPress` have been merged into `PointerInput`. The
use remains exactly the same.
+ Picking interaction events are now only accessible through observers,
and no `EventReader`. This functionality may be re-implemented later.
For users of `bevy_winit`:
+ The event `bevy_winit::WinitEvent` has moved to
`bevy_window::WindowEvent`. If this was the only thing you depended on
`bevy_winit` for, you should switch your dependency to `bevy_window`.
+ `bevy_window` now depends on `bevy_input`. The dependencies of
`bevy_input` are a subset of the existing dependencies for `bevy_window`
so this should be non-breaking.
# Objective
Fixes#14883
## Solution
Pretty simple update to `EntityCommands` methods to consume `self` and
return it rather than taking `&mut self`. The things probably worth
noting:
* I added `#[allow(clippy::should_implement_trait)]` to the `add` method
because it causes a linting conflict with `std::ops::Add`.
* `despawn` and `log_components` now return `Self`. I'm not sure if
that's exactly the desired behavior so I'm happy to adjust if that seems
wrong.
## Testing
Tested with `cargo run -p ci`. I think that should be sufficient to call
things good.
## Migration Guide
The most likely migration needed is changing code from this:
```
let mut entity = commands.get_or_spawn(entity);
if depth_prepass {
entity.insert(DepthPrepass);
}
if normal_prepass {
entity.insert(NormalPrepass);
}
if motion_vector_prepass {
entity.insert(MotionVectorPrepass);
}
if deferred_prepass {
entity.insert(DeferredPrepass);
}
```
to this:
```
let mut entity = commands.get_or_spawn(entity);
if depth_prepass {
entity = entity.insert(DepthPrepass);
}
if normal_prepass {
entity = entity.insert(NormalPrepass);
}
if motion_vector_prepass {
entity = entity.insert(MotionVectorPrepass);
}
if deferred_prepass {
entity.insert(DeferredPrepass);
}
```
as can be seen in several of the example code updates here. There will
probably also be instances where mutable `EntityCommands` vars no longer
need to be mutable.
# Objective
Fixes#14782
## Solution
Enable the lint and fix all upcoming hints (`--fix`). Also tried to
figure out the false-positive (see review comment). Maybe split this PR
up into multiple parts where only the last one enables the lint, so some
can already be merged resulting in less many files touched / less
potential for merge conflicts?
Currently, there are some cases where it might be easier to read the
code with the qualifier, so perhaps remove the import of it and adapt
its cases? In the current stage it's just a plain adoption of the
suggestions in order to have a base to discuss.
## Testing
`cargo clippy` and `cargo run -p ci` are happy.
# Objective
- Add custom images as cursors
- Fixes#9557
## Solution
- Change cursor type to accommodate both native and image cursors
- I don't really like this solution because I couldn't use
`Handle<Image>` directly. I would need to import `bevy_assets` and that
causes a circular dependency. Alternatively we could use winit's
`CustomCursor` smart pointers, but that seems hard because the event
loop is needed to create those and is not easily accessable for users.
So now I need to copy around rgba buffers which is sad.
- I use a cache because especially on the web creating cursor images is
really slow
- Sorry to #14196 for yoinking, I just wanted to make a quick solution
for myself and thought that I should probably share it too.
Update:
- Now uses `Handle<Image>`, reads rgba data in `bevy_render` and uses
resources to send the data to `bevy_winit`, where the final cursors are
created.
## Testing
- Added example which works fine at least on Linux Wayland (winit side
has been tested with all platforms).
- I haven't tested if the url cursor works.
## Migration Guide
- `CursorIcon` is no longer a field in `Window`, but a separate
component can be inserted to a window entity. It has been changed to an
enum that can hold custom images in addition to system icons.
- `Cursor` is renamed to `CursorOptions` and `cursor` field of `Window`
is renamed to `cursor_options`
- `CursorIcon` is renamed to `SystemCursorIcon`

# Objective
Adds a new `Monitor` component representing a winit `MonitorHandle` that
can be used to spawn new windows and check for system monitor
information.
Closes#12955.
## Solution
For every winit event, check available monitors and spawn them into the
world as components.
## Testing
TODO:
- [x] Test plugging in and unplugging monitor during app runtime
- [x] Test spawning a window on a second monitor by entity id
- [ ] Since this touches winit, test all platforms
---
## Changelog
- Adds a new `Monitor` component that can be queried for information
about available system monitors.
## Migration Guide
- `WindowMode` variants now take a `MonitorSelection`, which can be set
to `MonitorSelection::Primary` to mirror the old behavior.

# Objective
- Fix issue #2611
## Solution
- Add `--generate-link-to-definition` to all the `rustdoc-args` arrays
in the `Cargo.toml`s (for docs.rs)
- Add `--generate-link-to-definition` to the `RUSTDOCFLAGS` environment
variable in the docs workflow (for dev-docs.bevyengine.org)
- Document all the workspace crates in the docs workflow (needed because
otherwise only the source code of the `bevy` package will be included,
making the argument useless)
- I think this also fixes#3662, since it fixes the bug on
dev-docs.bevyengine.org, while on docs.rs it has been fixed for a while
on their side.
---
## Changelog
- The source code viewer on docs.rs now includes links to the
definitions.
# Objective
- `bevy_winit` fails to build with just the `serialize` feature.
- Caught by [`flag-frenzy`](https://github.com/TheBevyFlock/flag-frenzy)
in [this
run](https://github.com/TheBevyFlock/flag-frenzy/actions/runs/10087486444/job/27891723948),
using the new, nuanced configuration system!
## Solution
- It was failing because `bevy_winit` did not pass the `serialize` flag
to two of its dependencies: `bevy_input` and `bevy_window`.
- To fix this, add these crates to the feature flag.
## Testing
```bash
# On Linux, you must also specify a backend: `x11` or `wayland`.
# You can do this with `-F serialize,x11`, etc.
cargo check -p bevy_winit --no-default-features -F serialize
```
# Objective
- Continue to pare down the uses on NonSend resources in the engine. In
this case, EventLoopProxy used to be `!Sync`, but is now `Sync` in the
latest version of winit.
## Solution
- New type `EventLoopProxy` as `EventLoopProxyWrapper` to make it into a
normal resource.
- Update the `custom_user_event` example as it no longer needs to
indirectly access the `EventLoopProxy` through a static variable
anymore.
## Testing
- Ran the example. The resource exists just for users to use, so there
aren't any in engine uses for it currently.
---
## Changelog
- make EventLoopProxy into a regular resource.
## Migration Guide
`EventLoopProxy` has been renamed to `EventLoopProxyWrapper` and is now
`Send`, making it an ordinary resource.
Before:
```rust
event_loop_system(event_loop: NonSend<EventLoopProxy<MyEvent>>) {
event_loop.send_event(MyEvent);
}
```
After:
```rust
event_loop_system(event_loop: Res<EventLoopProxy<MyEvent>>) {
event_loop.send_event(MyEvent);
}
```
# Objective
I would like to know if an event was emitted because of "key repeats" or
not.
Winit already exposes this information, but it isn't sent along by Bevy,
which this PR intends to address.
## Solution
Expose
[`winit::event::KeyEvent::repeat`](https://docs.rs/winit/0.30.3/winit/event/struct.KeyEvent.html#structfield.repeat)
in
[`bevy::input:⌨️:KeyboardInput`](https://docs.rs/bevy/0.14.0/bevy/input/keyboard/struct.KeyboardInput.html).
## Testing
Just hold any regular key down and only the first event should have
`KeyboardInput::repeat` set to `false`. Most OSs have "key repeat"
enabled by default.
---
## Changelog
- Added `KeyboardInput::repeat` signifying if this event was sent in
response to a "key repeat" event or not.
# Objective
- Bevy currently has lot of invalid intra-doc links, let's fix them!
- Also make CI test them, to avoid future regressions.
- Helps with #1983 (but doesn't fix it, as there could still be explicit
links to docs.rs that are broken)
## Solution
- Make `cargo r -p ci -- doc-check` check fail on warnings (could also
be changed to just some specific lints)
- Manually fix all the warnings (note that in some cases it was unclear
to me what the fix should have been, I'll try to highlight them in a
self-review)
# Objective
- Often in games you will want to create chains of systems that modify
some event. For example, a chain of damage systems that handle a
DamageEvent and modify the underlying value before the health system
finally consumes the event. Right now this requires either:
* Using a component added to the entity
* Consuming and refiring events
Neither is ideal when really all we want to do is read the events value,
modify it, and write it back.
## Solution
- Create an EventMutator class similar to EventReader but with ResMut<T>
and iterators that return &mut so that events can be mutated.
## Testing
- I replicated all the existing tests for EventReader to make sure
behavior was the same (I believe) and added a number of tests specific
to testing that 1) events can actually be mutated, and that 2)
EventReader sees changes from EventMutator for events it hasn't already
seen.
## Migration Guide
Users currently using `ManualEventReader` should use `EventCursor`
instead. `ManualEventReader` will be removed in Bevy 0.16. Additionally,
`Events::get_reader` has been replaced by `Events::get_cursor`.
Users currently directly accessing the `Events` resource for mutation
should move to `EventMutator` if possible.

## Changelog
- Update `accesskit` to 0.16 and `accesskit_winit` to 0.22.
## Migration Guide
`accesskit`'s `Role::StaticText` variant has been renamed to
`Role::Label`.
# Objective
- Fixes#13702
- When creating a new window, its scale was changed to match the one
returned by winit, but its size was not which resulted in an incorrect
size until the event with the correct size was received, at least 1
frame later
## Solution
- Apply the window scale to its size when creating it
Fixes#13701
After `winit` upgrade to `0.31`, windows were no longer correctly
resizing. This appears to just have been a simple mistake, where the new
physical size was being sourced from the `winit` window rather than on
the incoming `Window` component.
## Testing
Tested on macOS, but I'm curious whether this was also broken on other
platforms.
# Objective
Fixes#13299
On Linux/X11, changing focus into a winit window will produce winit
KeyboardInput events with a "is_synthetic=true" flag that are not
intended to be used. Bevy erroneously passes them on to the user,
resulting in phantom key presses.
## Solution
This patch properly filters out winit KeyboardInput events with
"is_synthetic=true".
For example, pressing Alt+Tab to focus a bevy winit window results in a
permanently stuck Tab key until the user presses Tab once again to
produce a winit KeyboardInput release event. The Tab key press event
that causes this problem is "synthetic", should not be used according to
the winit devs, and simply ignoring it fixes this problem.
Synthetic key **releases** are still evaluated though, as they are
essential for correct release key handling. For example, if the user
binds the key combination Alt+1 to the action "move the window to
workspace 1", places the bevy game in workspace 2, focuses the game and
presses Alt+1, then the key release event for the "1" key will be
synthetic. If we would filter out all synthetic keys, the bevy game
would think that the 1 key remains pressed forever, until the user
manually presses+releases the key again inside bevy.
Reference:
https://docs.rs/winit/0.30.0/winit/event/enum.WindowEvent.html#variant.KeyboardInput.field.is_synthetic
Relevant discussion: https://github.com/rust-windowing/winit/issues/3543
## Testing
Tested with the "keyboard_input_events" example. Entering/exiting the
window with various keys, as well as changing its workspace, produces
the correct press/release events.
# Objective
- On macOS, closing a window by respawning its entity freezes
## Solution
- `WindowWrapper` is keeping an `Arc` of the window, to be able to
access it from the rendering thread. Winit windows are closed when they
are dropped. This need to happen on the main thread on macOS
- Dropping it as soon as the window is closed means the last remaining
`Arc` will be in the rendering thread
- This PR keeps the `Arc` for one frame in the rendering thread before
actually dropping it
This was adopted from #12878. I rebased the changes resolved the
following merge conflicts:
- moved over the changes originally done in bevy_winit/src/lib.rs's
`handle_winit_event` into bevy_winit/src/state.rs's `window_event`
function
- moved WinitEvent::KeyboardFocusLost event forwarding originally done
in bevy_winit/src/winit_event.rs to the equivalent in
bevy_winit/src/state.rs
Tested this by following the modified keyboard_input example from the
original PR.
First, I verified I could reproduce the issue without the changes. Then,
after applying the changes, I verified that when I Alt+Tabbed away from
the running example that the log showed I released Alt and when I tabbed
back it didn't behave like Alt was stuck.
The following is from the original pull request by @gavlig
# Objective
This helps avoiding stuck key presses after switching from and back to
Bevy window. Key press event gets stuck because window loses focus
before receiving a key release event thus we end up with false positive
in ButtonInput.
## Solution
I saw two ways to fix this:
1. add bevy_window as dependency and read WindowFocus events
2. add a KeyboardFocusLost event specifically for this.
I chose the latter because adding another dependency felt wrong, but if
that is more preferable changing this pr won't be a problem. Also if
someone sees another way please let me know.
To test the bug use this small modification over
examples/keyboard_input.rs: (it will work only if you have Alt-Tab
combination for switching between windows in your OS, otherwise change
AltLeft accordingly)
```
//! Demonstrates handling a key press/release.
use bevy::{prelude::*, input:⌨️:KeyboardInput};
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_systems(Update, keyboard_input_system)
.run();
}
/// This system prints 'Alt' key state
fn keyboard_input_system(keyboard_input: Res<ButtonInput<KeyCode>>, mut
keyboard_input_events: EventReader<KeyboardInput>) {
for event in keyboard_input_events.read() {
info!("{:?}", event);
}
if keyboard_input.pressed(KeyCode::AltLeft) {
info!("'Alt' currently pressed");
}
if keyboard_input.just_pressed(KeyCode::AltLeft) {
info!("'Alt' just pressed");
}
if keyboard_input.just_released(KeyCode::AltLeft) {
info!("'Alt' just released");
}
}
```
Here i made a quick video with demo of the fix:
https://youtu.be/qTvUCk4IHvo In first part i press Alt and Alt+Tab to
switch back and forth from example app, logs will indicate that too. In
second part I applied fix and you'll see that Alt will no longer be
pressed when window gets unfocused

`WinitEvent` has a new enum variant: `WinitEvent::KeyboardFocusLost`.

# Objective
- Upgrade winit to v0.30
- Fixes https://github.com/bevyengine/bevy/issues/13331
## Solution
This is a rewrite/adaptation of the new trait system described and
implemented in `winit` v0.30.
## Migration Guide
The custom UserEvent is now renamed as WakeUp, used to wake up the loop
if anything happens outside the app (a new
[custom_user_event](https://github.com/bevyengine/bevy/pull/13366/files#diff-2de8c0a8d3028d0059a3d80ae31b2bbc1cde2595ce2d317ea378fe3e0cf6ef2d)
shows this behavior.
The internal `UpdateState` has been removed and replaced internally by
the AppLifecycle. When changed, the AppLifecycle is sent as an event.
The `UpdateMode` now accepts only two values: `Continuous` and
`Reactive`, but the latter exposes 3 new properties to enable reactive
to device, user or window events. The previous `UpdateMode::Reactive` is
now equivalent to `UpdateMode::reactive()`, while
`UpdateMode::ReactiveLowPower` to `UpdateMode::reactive_low_power()`.
The `ApplicationLifecycle` has been renamed as `AppLifecycle`, and now
contains the possible values of the application state inside the event
loop:
* `Idle`: the loop has not started yet
* `Running` (previously called `Started`): the loop is running
* `WillSuspend`: the loop is going to be suspended
* `Suspended`: the loop is suspended
* `WillResume`: the loop is going to be resumed
Note: the `Resumed` state has been removed since the resumed app is just
running.
Finally, now that `winit` enables this, it extends the `WinitPlugin` to
support custom events.
## Test platforms
- [x] Windows

- [x] Linux (x11)
- [x] Linux (Wayland)
- [x] Android

## Outstanding issues / regressions
- [ ] iOS: build failed in CI
- blocking, but may just be flakiness
- [x] Cross-platform: when the window is maximised, changes in the scale
factor don't apply, to make them apply one has to make the window
smaller again. (Re-maximising keeps the updated scale factor)
- non-blocking, but good to fix
- [ ] Android: it's pretty easy to quickly open and close the app and
then the music keeps playing when suspended.
- non-blocking but worrying
- [ ] Web: the application will hang when switching tabs
- Not new, duplicate of https://github.com/bevyengine/bevy/issues/13486
- [ ] Cross-platform?: Screenshot failure, `ERROR present_frames:
wgpu_core::present: No work has been submitted for this frame before`
taking the first screenshot, but after pressing space
- non-blocking, but good to fix

# Objective
Fixes two issues related to #13208.
First, we ensure render resources for a window are always dropped first
to ensure that the `winit::Window` always drops on the main thread when
it is removed from `WinitWindows`. Previously, changes in #12978 caused
the window to drop in the render world, causing issues.
We accomplish this by delaying despawning the window by a frame by
inserting a marker component `ClosingWindow` that indicates the window
has been requested to close and is in the process of closing. The render
world now responds to the equivalent `WindowClosing` event rather than
`WindowCloseed` which now fires after the render resources are
guarunteed to be cleaned up.
Secondly, fixing the above caused (revealed?) that additional events
were being delivered to the the event loop handler after exit had
already been requested: in my testing `RedrawRequested` and
`LoopExiting`. This caused errors to be reported try to send an exit
event on the close channel. There are two options here:
- Guard the handler so no additional events are delivered once the app
is exiting. I ~considered this but worried it might be confusing or bug
prone if in the future someone wants to handle `LoopExiting` or some
other event to clean-up while exiting.~ We are now taking this approach.
- Only send an exit signal if we are not already exiting. ~It doesn't
appear to cause any problems to handle the extra events so this seems
safer.~
Fixing this also appears to have fixed#13231.
Fixes#10260.
## Testing
Tested on mac only.
---
## Changelog
### Added
- A `WindowClosing` event has been added that indicates the window will
be despawned on the next frame.
### Changed
- Windows now close a frame after their exit has been requested.
## Migration Guide
- Ensure custom exit logic does not rely on the app exiting the same
frame as a window is closed.
# Objective
~Returning a app exit code from the winit runner is complicated and
deadlock prone.~
The code to return a app exit code is rather shoddy. It's use of mutex
is redundant, It uses unwrap when not required and can be broken by a
maintainer simply forgetting to set a value.
## Solution
Switch to using a channel.
- Deals with situations in which a event loop exits unexpectedly.
- Never panics. Even in extreme cases.
# Objective
- Simplifies/clarifies the winit loop.
- Fixes#12612.
## Solution
The Winit loop runs following this flow:
* NewEvents
* Any number of other events, that can be 0, including RequestRedraw
* AboutToWait
Bevy also uses the UpdateMode, to define how the next loop has to run.
It can be essentially:
* Continuous, using ControlFlow::Wait for windowed apps, and
ControlFlow::Poll for windowless apps
* Reactive/ReactiveLowPower, using ControlFlow::WaitUntil with a
specific wait delay
The changes are made to follow this pattern, so that
* NewEvents define if the WaitUntil has been canceled because we
received a Winit event.
* AboutToWait:
* checks if the window has to be redrawn
* otherwise calls app.update() if the WaitUntil timeout has elapsed
* updates the ControlFlow accordingly
To make the code more logical:
* AboutToWait checks if any Bevy's RequestRedraw event has been emitted
* create_windows is run every cycle, at the beginning of the loop
* the ActiveState (that could be renamed ActivityState) is updated in
AboutToWait, symmetrically for WillSuspend/WillResume
* the AppExit events are checked every loop cycle, to exit the app early

# Objective
- `README.md` is a common file that usually gives an overview of the
folder it is in.
- When on <https://crates.io>, `README.md` is rendered as the main
description.
- Many crates in this repository are lacking `README.md` files, which
makes it more difficult to understand their purpose.
<img width="1552" alt="image"
src="https://github.com/bevyengine/bevy/assets/59022059/78ebf91d-b0c4-4b18-9874-365d6310640f">
- There are also a few inconsistencies with `README.md` files that this
PR and its follow-ups intend to fix.
## Solution
- Create a `README.md` file for all crates that do not have one.
- This file only contains the title of the crate (underscores removed,
proper capitalization, acronyms expanded) and the <https://shields.io>
badges.
- Remove the `readme` field in `Cargo.toml` for `bevy` and
`bevy_reflect`.
- This field is redundant because [Cargo automatically detects
`README.md`
files](https://doc.rust-lang.org/cargo/reference/manifest.html#the-readme-field).
The field is only there if you name it something else, like `INFO.md`.
- Fix capitalization of `bevy_utils`'s `README.md`.
- It was originally `Readme.md`, which is inconsistent with the rest of
the project.
- I created two commits renaming it to `README.md`, because Git appears
to be case-insensitive.
- Expand acronyms in title of `bevy_ptr` and `bevy_utils`.
- In the commit where I created all the new `README.md` files, I
preferred using expanded acronyms in the titles. (E.g. "Bevy Developer
Tools" instead of "Bevy Dev Tools".)
- This commit changes the title of existing `README.md` files to follow
the same scheme.
- I do not feel strongly about this change, please comment if you
disagree and I can revert it.
- Add <https://shields.io> badges to `bevy_time` and `bevy_transform`,
which are the only crates currently lacking them.
---
## Changelog
- Added `README.md` files to all crates missing it.
# Objective
A `RawWindowHandle` is only valid as long as the window it was retrieved
from is alive. Extend the lifetime of the window, so that the
`RawWindowHandle` doesn't outlive it, and bevy doesn't crash when
closing a window a pipelined renderer is drawing to.
- Fix#11236
- Fix#11150
- Fix#11734
- Alternative to / Closes#12524
## Solution
Introduce a `WindowWrapper` that takes ownership of the window. Require
it to be used when constructing a `RawHandleWrapper`. This forces
windowing backends to store their window in this wrapper.
The `WindowWrapper` is implemented by storing the window in an `Arc<dyn
Any + Send + Sync>`.
We use dynamic dispatch here because we later want the
`RawHandleWrapper` to be able dynamically hold a reference to any
windowing backend's window.
But alas, the `WindowWrapper` itself is still practically invisible to
windowing backends, because it implements `Deref` to the underlying
window, by storing its type in a `PhantomData`.
---
## Changelog
### Added
- Added `WindowWrapper`, which windowing backends are now required to
use to store their underlying window.
### Fixed
- Fixed a safety problem which caused crashes when closing bevy windows
when using pipelined rendering.
## Migration Guide
- Windowing backends now need to store their window in the new
`WindowWrapper`.
# Objective
- Partially resolves#12639.
## Solution
- Deprecate `ReceivedCharacter`.
- Replace `ReceivedCharacter` with `KeyboardInput` in the relevant
examples.
## Migration Guide
- `ReceivedCharacter` is now deprecated, use `KeyboardInput` instead.
- Before:
```rust
fn listen_characters(events: EventReader<ReceivedCharacter>) {
for event in events.read() {
info!("{}", event.char);
}
}
```
After:
```rust
fn listen_characters(events: EventReader<KeyboardInput>) {
for event in events.read() {
// Only check for characters when the key is pressed.
if event.state == ButtonState::Released {
continue;
}
// Note that some keys such as `Space` and `Tab` won't be detected as
before.
// Instead, check for them with `Key::Space` and `Key::Tab`.
if let Key::Character(character) = &event.logical_key {
info!("{}", character);
}
}
}
```

# Objective
Both the shedule and winit runners use/reimplement `app_exit_manual`
even tough they can use `app_exit`
## Solution
Nuke `app_exit_manual` from orbit.
# Objective
Closes#13017.
## Solution
- Make `AppExit` a enum with a `Success` and `Error` variant.
- Make `App::run()` return a `AppExit` if it ever returns.
- Make app runners return a `AppExit` to signal if they encountered a
error.
---
## Changelog
### Added
- [`App::should_exit`](https://example.org/)
- [`AppExit`](https://docs.rs/bevy/latest/bevy/app/struct.AppExit.html)
to the `bevy` and `bevy_app` preludes,
### Changed
- [`AppExit`](https://docs.rs/bevy/latest/bevy/app/struct.AppExit.html)
is now a enum with 2 variants (`Success` and `Error`).
- The app's [runner
function](https://docs.rs/bevy/latest/bevy/app/struct.App.html#method.set_runner)
now has to return a `AppExit`.
-
[`App::run()`](https://docs.rs/bevy/latest/bevy/app/struct.App.html#method.run)
now also returns the `AppExit` produced by the runner function.
## Migration Guide
- Replace all usages of
[`AppExit`](https://docs.rs/bevy/latest/bevy/app/struct.AppExit.html)
with `AppExit::Success` or `AppExit::Failure`.
- Any custom app runners now need to return a `AppExit`. We suggest you
return a `AppExit::Error` if any `AppExit` raised was a Error. You can
use the new [`App::should_exit`](https://example.org/) method.
- If not exiting from `main` any other way. You should return the
`AppExit` from `App::run()` so the app correctly returns a error code if
anything fails e.g.
```rust
fn main() -> AppExit {
App::new()
//Your setup here...
.run()
}
```

# Objective
- https://github.com/rust-lang/rust/pull/123905 has been merged, so the
workaround introduced in #12913 is no longer necessary.
- Closes#12968
## Solution
- Remove unecessary `allow` attribute
- This is currently blocked until Rust beta updates.
- Last tested with `rustc 1.78.0-beta.7 (6fd191292 2024-04-12)`.
# Objective
- Fixes#13024.
## Solution
- Run `cargo clippy --target wasm32-unknown-unknown` until there are no
more errors.
- I recommend reviewing one commit at a time :)
---
## Changelog
- Fixed Clippy lints for `wasm32-unknown-unknown` target.
- Updated `bevy_transform`'s `README.md`.
# Objective
- Fixes#12905.
## Solution
- Use proper code `` tags for `TaskPoolBuilder::thread_name`.
- Remove leftover documentation in `TaskPool` referencing the deleted
`TaskPoolInner` struct.
- It may be possible to rephrase this, but I do not know enough about
the task pool to write something. (cc @james7132 who made the change
removing `TaskPoolInner`.)
- Ignore a buggy rustdoc lint that thinks `App` is already in scope for
`UpdateMode` doc. (Extracted from #12692.)
# Objective
This is a necessary precursor to #9122 (this was split from that PR to
reduce the amount of code to review all at once).
Moving `!Send` resource ownership to `App` will make it unambiguously
`!Send`. `SubApp` must be `Send`, so it can't wrap `App`.
## Solution
Refactor `App` and `SubApp` to not have a recursive relationship. Since
`SubApp` no longer wraps `App`, once `!Send` resources are moved out of
`World` and into `App`, `SubApp` will become unambiguously `Send`.
There could be less code duplication between `App` and `SubApp`, but
that would break `App` method chaining.
## Changelog
- `SubApp` no longer wraps `App`.
- `App` fields are no longer publicly accessible.
- `App` can no longer be converted into a `SubApp`.
- Various methods now return references to a `SubApp` instead of an
`App`.
## Migration Guide
- To construct a sub-app, use `SubApp::new()`. `App` can no longer
convert into `SubApp`.
- If you implemented a trait for `App`, you may want to implement it for
`SubApp` as well.
- If you're accessing `app.world` directly, you now have to use
`app.world()` and `app.world_mut()`.
- `App::sub_app` now returns `&SubApp`.
- `App::sub_app_mut` now returns `&mut SubApp`.
- `App::get_sub_app` now returns `Option<&SubApp>.`
- `App::get_sub_app_mut` now returns `Option<&mut SubApp>.`
# Objective
- Allow cloning `WinitSettings`. I use this in
[bevy_worldswap](https://github.com/UkoeHB/bevy_worldswap) when
synchronizing secondary app window state.
## Solution
- Add `Clone` to `WinitSettings`.
---
## Changelog
- Added `Clone` to `WinitSettings`.
# Objective
- Reduce the size of `create_windows` and isolate accessibility setup
logic.
## Solution
- Move accessibility setup for new windows to the `accessibility`
module.
## Comments
This is a small refactor, no behavior changes.
# Objective
- Avoid unbounded HashMap growth for opening/closing windows.
## Solution
- Remove map entry in `WinitWindows::remove_window`.
## Migration Guide
- `WinitWindows::get_window_entity` now returns `None` after a window is
closed, instead of a dead entity.
---
## Comments
The comment this PR replaces was added in
https://github.com/bevyengine/bevy/pull/3575. Since `get_window_entity`
now returns an `Entity` instead of a `WindowId`, this no longer seems
useful. Note that `get_window_entity` is only used
[here](56bcbb0975/crates/bevy_winit/src/lib.rs (L436)),
immediately followed by a warning if the entity returned doesn't exist.
# Objective
Resolves#3824. `unsafe` code should be the exception, not the norm in
Rust. It's obviously needed for various use cases as it's interfacing
with platforms and essentially running the borrow checker at runtime in
the ECS, but the touted benefits of Bevy is that we are able to heavily
leverage Rust's safety, and we should be holding ourselves accountable
to that by minimizing our unsafe footprint.
## Solution
Deny `unsafe_code` workspace wide. Add explicit exceptions for the
following crates, and forbid it in almost all of the others.
* bevy_ecs - Obvious given how much unsafe is needed to achieve
performant results
* bevy_ptr - Works with raw pointers, even more low level than bevy_ecs.
* bevy_render - due to needing to integrate with wgpu
* bevy_window - due to needing to integrate with raw_window_handle
* bevy_utils - Several unsafe utilities used by bevy_ecs. Ideally moved
into bevy_ecs instead of made publicly usable.
* bevy_reflect - Required for the unsafe type casting it's doing.
* bevy_transform - for the parallel transform propagation
* bevy_gizmos - For the SystemParam impls it has.
* bevy_assets - To support reflection. Might not be required, not 100%
sure yet.
* bevy_mikktspace - due to being a conversion from a C library. Pending
safe rewrite.
* bevy_dynamic_plugin - Inherently unsafe due to the dynamic loading
nature.
Several uses of unsafe were rewritten, as they did not need to be using
them:
* bevy_text - a case of `Option::unchecked` could be rewritten as a
normal for loop and match instead of an iterator.
* bevy_color - the Pod/Zeroable implementations were replaceable with
bytemuck's derive macros.
# Objective
Currently the built docs only shows the logo and favicon for the top
level `bevy` crate. This makes views like
https://docs.rs/bevy_ecs/latest/bevy_ecs/ look potentially unrelated to
the project at first glance.
## Solution
Reproduce the docs attributes for every crate that Bevy publishes.
Ideally this would be done with some workspace level Cargo.toml control,
but AFAICT, such support does not exist.
# Objective
Fix Pr CI failing over dead code in tests and main branch CI failing
over a missing semicolon. Fixes#12620.
## Solution
Add dead_code annotations and a semicolon.
# Objective
Resolves#12431.
## Solution
Added a `skip_taskbar` field to the `Window` struct (defaults to
`false`). Used in `create_windows` if the target OS is Windows.
# Objective
To have a user level workaround for #12237.
## Solution
Workaround to the problem is described in:
https://github.com/bevyengine/bevy/issues/12237#issuecomment-1983680632
## Changelog
### Changed
- `CreateWindowParams` type and `create_windows` system from
`bevy_winit` is now public, which allows library authors and game
developers to manually trigger window creation when needed.
# Objective
Fix missing `TextBundle` (and many others) which are present in the main
crate as default features but optional in the sub-crate. See:
- https://docs.rs/bevy/0.13.0/bevy/ui/node_bundles/index.html
- https://docs.rs/bevy_ui/0.13.0/bevy_ui/node_bundles/index.html
~~There are probably other instances in other crates that I could track
down, but maybe "all-features = true" should be used by default in all
sub-crates? Not sure.~~ (There were many.) I only noticed this because
rust-analyzer's "open docs" features takes me to the sub-crate, not the
main one.
## Solution
Add "all-features = true" to docs.rs metadata for crates that use
features.
## Changelog
### Changed
- Unified features documented on docs.rs between main crate and
sub-crates
# Objective
Fixes#12126
Notably this does not appear to fix the console error spam that appears
to be coming from winit, only the performance bug that occurs when
tabbing out and back into the game.
## Solution
The winit event loop starts out as `ControlFlow::Wait` by default. When
switching to `UpdateMode::Reactive` or `UpdateMode::ReactiveLowPower`,
we repeatedly update this to `ControlFlow::WaitUntil(next)`. When
switching back to `UpdateMode::Continuous`, the event loop is
erroneously stuck at the latest `ControlFlow::WaitUntil(next)` that was
issued.
I also changed how we handle `Event::NewEvents` since the `StartCause`
already tells us enough information to make that decision. This came
about my debugging and I left it in as an improvement.
Hi, this is a minimal implementation of #12159. I wasn't sure if the
`EventLoopProxy` should be wrapped somewhat to make it more explicit.
# Objective
Minimal implementation of #12159
When using `UpdateMode::Reactive` it is currently not possible to
request a redraw when a long running task is finished or an external
source has new data.
This makes the following possible which will then run an app update once
``` rust
// EventLoopProxy is Send on most architectures
// The EventLoopProxy can also be saved in a thread local for WASM or a static in other architecturecs
pub fn example(proxy: NonSend<EventLoopProxy<()>>) {
let clone: EventLoopProxy<()> = proxy.clone();
thread::spawn(move || {
// do long work
clone.send_event(());
});
}
```
## Solution
By using the EventLoopProxy one can manually send events from external
threads to the event loop as `UserEvent`s.
This simply sets redraw_requested when a `UserEvent` is received.
## Changelog
- Added the ability to request a redraw from an external source
---------
Co-authored-by: Kellner, Robin <Robin.Kellner@vector.com>
# Objective
- Allow users to read window events in the sequence they appeared. This
is important for precise input handling when there are multiple input
events in a single frame (e.g. click and release vs release and click).
## Solution
- Add a mega-enum `WinitEvent` that collects window events, and send
those alongside the existing more granular window events.
---
## Changelog
- Added `WinitEvent` event that aggregates all window events into a
synchronized event stream.
Follow up to #11057
Implemented suggestions from reviewers from: a simpler
fit_canvas_to_parent leads to an explicit CSS setting to the canvas.
From my understanding, it has do be set after wgpu creation due to wgpu
overriding the canvas width/height:
4400a58470/examples/src/utils.rs (L68-L74)
# Changelog
- Re-enable a `fit_canvas_to_parent`, it's removal from
https://github.com/bevyengine/bevy/pull/11057 was problematic. Still,
its inner working is more simple than before: bevy doesn't handle its
resizing, winit does.
## Migration Guide
- Cancels the migration from
https://github.com/bevyengine/bevy/pull/11057
# Objective
- Add the new `-Zcheck-cfg` checks to catch more warnings
- Fixes#12091
## Solution
- Create a new `cfg-check` to the CI that runs `cargo check -Zcheck-cfg
--workspace` using cargo nightly (and fails if there are warnings)
- Fix all warnings generated by the new check
---
## Changelog
- Remove all redundant imports
- Fix cfg wasm32 targets
- Add 3 dead code exceptions (should StandardColor be unused?)
- Convert ios_simulator to a feature (I'm not sure if this is the right
way to do it, but the check complained before)
## Migration Guide
No breaking changes

Co-authored-by: François <mockersf@gmail.com>
# Objective
- Fixes#11695
## Solution
- Added `delta: Option<Vec2>` to `bevy_window::CursorMoved`. `delta` is
an `Option` because the `CursorMoved` event does get fired when the
cursor was outside the window area in the last frame. In that case there
is no cursor position from the last frame to compare with the current
cursor position.
---
## Changelog
- Added `delta: Option<Vec2>` to `bevy_window::CursorMoved`.
## Migration Guide
- You need to add `delta` to any manually created `CursorMoved` struct.

# Objective
Reduce the size of `bevy_utils`
(https://github.com/bevyengine/bevy/issues/11478)
## Solution
Move `EntityHash` related types into `bevy_ecs`. This also allows us
access to `Entity`, which means we no longer need `EntityHashMap`'s
first generic argument.
---
## Changelog
- Moved `bevy::utils::{EntityHash, EntityHasher, EntityHashMap,
EntityHashSet}` into `bevy::ecs::entity::hash` .
- Removed `EntityHashMap`'s first generic argument. It is now hardcoded
to always be `Entity`.
## Migration Guide
- Uses of `bevy::utils::{EntityHash, EntityHasher, EntityHashMap,
EntityHashSet}` now have to be imported from `bevy::ecs::entity::hash`.
- Uses of `EntityHashMap` no longer have to specify the first generic
parameter. It is now hardcoded to always be `Entity`.
# Objective
- Get rid of unwraps in winit fullscreen handling code, which are the
source of some crashes.
- Fix#11275
## Solution
- Replace the unwraps with warnings. Ignore the fullscreen request, do
nothing instead.
# Objective
- Fixes #4188, make users could set application ID for bevy apps.
## Solution
- Add `name` field to `bevy:🪟:Window`. Specifying this field adds
different properties to the window: application ID on `Wayland`,
`WM_CLASS` on `X11`, or window class name on Windows. It has no effect
on other platforms.
---
## Changelog
### Added
- Add `name` to `bevy:🪟:Window`.
## Migration Guide
- Set the `bevy_window::Window`'s `name` field when needed:
```rust
App::new()
.add_plugins(DefaultPlugins.set(WindowPlugin {
primary_window: Some(Window {
title: "I am a window!".into(),
name: Some("SpaceGameCompany.SpaceShooter".into()),
..default()
}),
..default()
}))
.run();

# Objective
Currently the `missing_docs` lint is allowed-by-default and enabled at
crate level when their documentations is complete (see #3492).
This PR proposes to inverse this logic by making `missing_docs`
warn-by-default and mark crates with imcomplete docs allowed.
## Solution
Makes `missing_docs` warn at workspace level and allowed at crate level
when the docs is imcomplete.
# Objective
Get #11257 changes merged.
I rewrote them one by one checking each to ensure correctness. In
particular, the window rescale logic changes to accomodate mut app
access are double checked. Not all changes have been included as some of
bevy_winit has since changed, and i am not confident including them.
Namely, the `run_app_update_if_should` change.

## Changelog
* `bevy:🪟:WindowMoved`'s `entity` field has been renamed to

## Migration Guide
`bevy:🪟:WindowMoved`'s `entity` field has been renamed to
`window`. This is to be more consistent with other windowing events.
Consider changing usage:

# Objective
Keep core dependencies up to date.
## Solution
Update the dependencies.
wgpu 0.19 only supports raw-window-handle (rwh) 0.6, so bumping that was
included in this.
The rwh 0.6 version bump is just the simplest way of doing it. There
might be a way we can take advantage of wgpu's new safe surface creation
api, but I'm not familiar enough with bevy's window management to
untangle it and my attempt ended up being a mess of lifetimes and rustc
complaining about missing trait impls (that were implemented). Thanks to
@MiniaczQ for the (much simpler) rwh 0.6 version bump code.
Unblocks https://github.com/bevyengine/bevy/pull/9172 and
https://github.com/bevyengine/bevy/pull/10812
~~This might be blocked on cpal and oboe updating their ndk versions to
0.8, as they both currently target ndk 0.7 which uses rwh 0.5.2~~ Tested
on android, and everything seems to work correctly (audio properly stops
when minimized, and plays when re-focusing the app).
---
## Changelog
- `wgpu` has been updated to 0.19! The long awaited arcanization has
been merged (for more info, see
https://gfx-rs.github.io/2023/11/24/arcanization.html), and Vulkan
should now be working again on Intel GPUs.
- Targeting WebGPU now requires that you add the new `webgpu` feature
(setting the `RUSTFLAGS` environment variable to
`--cfg=web_sys_unstable_apis` is still required). This feature currently
overrides the `webgl2` feature if you have both enabled (the `webgl2`
feature is enabled by default), so it is not recommended to add it as a
default feature to libraries without putting it behind a flag that
allows library users to opt out of it! In the future we plan on
supporting wasm binaries that can target both webgl2 and webgpu now that
wgpu added support for doing so (see
https://github.com/bevyengine/bevy/issues/11505).
- `raw-window-handle` has been updated to version 0.6.
## Migration Guide
- `bevy_render::instance_index::get_instance_index()` has been removed
as the webgl2 workaround is no longer required as it was fixed upstream
in wgpu. The `BASE_INSTANCE_WORKAROUND` shaderdef has also been removed.
- WebGPU now requires the new `webgpu` feature to be enabled. The
`webgpu` feature currently overrides the `webgl2` feature so you no
longer need to disable all default features and re-add them all when
targeting `webgpu`, but binaries built with both the `webgpu` and
`webgl2` features will only target the webgpu backend, and will only
work on browsers that support WebGPU.
- Places where you conditionally compiled things for webgl2 need to be
updated because of this change, eg:
- `#[cfg(any(not(feature = "webgl"), not(target_arch = "wasm32")))]`
becomes `#[cfg(any(not(feature = "webgl") ,not(target_arch = "wasm32"),
feature = "webgpu"))]`
- `#[cfg(all(feature = "webgl", target_arch = "wasm32"))]` becomes
`#[cfg(all(feature = "webgl", target_arch = "wasm32", not(feature =
"webgpu")))]`
- `if cfg!(all(feature = "webgl", target_arch = "wasm32"))` becomes `if
cfg!(all(feature = "webgl", target_arch = "wasm32", not(feature =
"webgpu")))`
- `create_texture_with_data` now also takes a `TextureDataOrder`. You
can probably just set this to `TextureDataOrder::default()`
- `TextureFormat`'s `block_size` has been renamed to `block_copy_size`
- See the `wgpu` changelog for anything I might've missed:

# Objective
- Partial fix for #11235
- Fixes#11274
- Fixes#11320
- Fixes#11273
## Solution
- check update mode to trigger redraw request, instead of once a redraw
request has been triggered
- don't ignore device event in case of `Reactive` update mode
- make sure that at least 5 updates are triggered on application start
to ensure everything is correctly initialized
- trigger manual updates instead of relying on redraw requests when
there are no window or they are not visible
# Objective
In the past `winit:🪟:Window` was not Send + Sync on web.
https://github.com/rust-windowing/winit/pull/2834 made
`winit:🪟:Window` Sync + Send so Bevy's `unsafe impl` is no longer
necessary.
## Solution
Remove the unsafe impls.
# Objective
- Since #11227, Bevy doesn't work on mobile anymore. Windows are not
created.
## Solution
- Create initial window on mobile after the initial `Resume` event.
macOS is included because it's excluded from the other initial window
creation and I didn't want it to feel alone. Also, it makes sense. this
is needed for Android
cfcb6885e3/crates/bevy_winit/src/lib.rs (L152)
- request redraw during plugin initialisation (needed for WebGPU)
- request redraw when receiving `AboutToWait` instead of at the end of
the event handler. request to redraw during a `RedrawRequested` event
are ignored on iOS
# Objective
- Since #10702, the way bevy updates the window leads to major slowdowns
as seen in
- #11122
- #11220
- Slow is bad, furthermore, _very_ slow is _very_ bad. We should fix
this issue.
## Solution
- Move the app update code into the `Event::WindowEvent { event:
WindowEvent::RedrawRequested }` branch of the event loop.
- Run `window.request_redraw()` When `runner_state.redraw_requested`
- Instead of swapping `ControlFlow` between `Poll` and `Wait`, we always
keep it at `Wait`, and use `window.request_redraw()` to schedule an
immediate call to the event loop.
- `runner_state.redraw_requested` is set to `true` when
`UpdateMode::Continuous` and when a `RequestRedraw` event is received.
- Extract the redraw code into a separate function, because otherwise
I'd go crazy with the indentation level.
- Fix#11122.
## Testing
I tested the WASM builds as follow:
```sh
cargo run -p build-wasm-example -- --api webgl2 bevymark
python -m http.server --directory examples/wasm/ 8080
# Open browser at http://localhost:8080
```
On main, even spawning a couple sprites is super choppy. Even if it says
"300 FPS". While on this branch, it is smooth as butter.
I also found that it fixes all choppiness on window resize (tested on
Linux/X11). This was another issue from #10702 IIRC.
So here is what I tested:
- On `wasm`: `many_foxes` and `bevymark`, with `argh::from_env()`
commented out, otherwise we get a cryptic error.
- Both with `PresentMode::AutoVsync` and `PresentMode::AutoNoVsync`
- On main, it is consistently choppy.
- With this PR, the visible frame rate is consistent with the diagnostic
numbers
- On native (linux/x11) I ran similar tests, making sure that
`AutoVsync` limits to monitor framerate, and `AutoNoVsync` doesn't.
## Future work
Code could be improved, I wanted a quick solution easy to review, but we
really need to make the code more accessible.
- #9768
- ~~**`WinitSettings::desktop_app()` is completely borked.**~~ actually
broken on main as well
### Review guide

## Solution
- Re-add lost negation
# Objective
If you have multiple windows, there is no way to determine which window
a `TouchInput` event applies to. This fixes that.
## Solution
- Add the window entity directly to `TouchInput`, just like the other
input events.
- Fixes#6011.
## Migration Guide
+ Add a `window` field when constructing or destructuring a `TouchInput`
struct.
Improves #11052
# Changelog
- Remove `Window::fit_canvas_to_parent`, as its resizing on wasm now
respects its CSS configuration.
## Migration Guide
- Remove uses of `Window::fit_canvas_to_parent` in favor of CSS
properties, for example:
```css
canvas {
width: 100%;
height: 100%;
}
```
# Objective
- Update winit dependency to 0.29
## Changelog
### KeyCode changes
- Removed `ScanCode`, as it was [replaced by
KeyCode](https://github.com/rust-windowing/winit/blob/master/CHANGELOG.md#0292).
- `ReceivedCharacter.char` is now a `SmolStr`, [relevant
doc](https://docs.rs/winit/latest/winit/event/struct.KeyEvent.html#structfield.text).
- Changed most `KeyCode` values, and added more.
KeyCode has changed meaning. With this PR, it refers to physical
position on keyboard rather than the printed letter on keyboard keys.
In practice this means:
- On QWERTY keyboard layouts, nothing changes
- On any other keyboard layout, `KeyCode` no longer reflects the label
on key.
- This is "good". In bevy 0.12, when you used WASD for movement, users
with non-QWERTY keyboards couldn't play your game! This was especially
bad for non-latin keyboards. Now, WASD represents the physical keys. A
French player will press the ZQSD keys, which are near each other,
Kyrgyz players will use "Цфыв".
- This is "bad" as well. You can't know in advance what the label of the
key for input is. Your UI says "press WASD to move", even if in reality,
they should be pressing "ZQSD" or "Цфыв". You also no longer can use
`KeyCode` for text inputs. In any case, it was a pretty bad API for text
input. You should use `ReceivedCharacter` now instead.
### Other changes
- Use `web-time` rather than `instant` crate.
(https://github.com/rust-windowing/winit/pull/2836)
- winit did split `run_return` in `run_onDemand` and `pump_events`, I
did the same change in bevy_winit and used `pump_events`.
- Removed `return_from_run` from `WinitSettings` as `winit::run` now
returns on supported platforms.
- I left the example "return_after_run" as I think it's still useful.
- This winit change is done partly to allow to create a new window after
quitting all windows: https://github.com/emilk/egui/issues/1918 ; this
PR doesn't address.
- added `width` and `height` properties in the `canvas` from wasm
example
(https://github.com/bevyengine/bevy/pull/10702#discussion_r1420567168)
## Known regressions (important follow ups?)
- Provide an API for reacting when a specific key from current layout
was released.
- possible solutions: use winit::Key from winit::KeyEvent ; mapping
between KeyCode and Key ; or .
- We don't receive characters through alt+numpad (e.g. alt + 151 = "ù")
anymore ; reproduced on winit example "ime". maybe related to
https://github.com/rust-windowing/winit/issues/2945
- (windows) Window content doesn't refresh at all when resizing. By
reading https://github.com/rust-windowing/winit/issues/2900 ; I suspect
we should just fire a `window.request_redraw();` from `AboutToWait`, and
handle actual redrawing within `RedrawRequested`. I'm not sure how to
move all that code so I'd appreciate it to be a follow up.
- (windows) unreleased winit fix for using set_control_flow in
AboutToWait https://github.com/rust-windowing/winit/issues/3215 ; ⚠️ I'm
not sure what the implications are, but that feels bad 🤔
## Follow up
I'd like to avoid bloating this PR, here are a few follow up tasks
worthy of a separate PR, or new issue to track them once this PR is
closed, as they would either complicate reviews, or at risk of being
controversial:
- remove CanvasParentResizePlugin
(https://github.com/bevyengine/bevy/pull/10702#discussion_r1417068856)
- avoid mentionning explicitly winit in docs from bevy_window ?
- NamedKey integration on bevy_input:
https://github.com/rust-windowing/winit/pull/3143 introduced a new
NamedKey variant. I implemented it only on the converters but we'd
benefit making the same changes to bevy_input.
- Add more info in KeyboardInput
https://github.com/bevyengine/bevy/pull/10702#pullrequestreview-1748336313
- https://github.com/bevyengine/bevy/pull/9905 added a workaround on a
bug allegedly fixed by winit 0.29. We should check if it's still
necessary.
- update to raw_window_handle 0.6
- blocked by wgpu
- Rename `KeyCode` to `PhysicalKeyCode`
https://github.com/bevyengine/bevy/pull/10702#discussion_r1404595015
- remove `instant` dependency, [replaced
by](https://github.com/rust-windowing/winit/pull/2836) `web_time`), we'd
need to update to :
- fastrand >= 2.0
- [`async-executor`](https://github.com/smol-rs/async-executor) >= 1.7
- [`futures-lite`](https://github.com/smol-rs/futures-lite) >= 2.0
- Verify license, see
[discussion](https://github.com/bevyengine/bevy/pull/8745#discussion_r1402439800)
- we might be missing a short notice or description of changes made
- Consider using https://github.com/rust-windowing/cursor-icon directly
rather than vendoring it in bevy.
- investigate [this
unwrap](https://github.com/bevyengine/bevy/pull/8745#discussion_r1387044986)
(`winit_window.canvas().unwrap();`)
- Use more good things about winit's update
- https://github.com/bevyengine/bevy/pull/10689#issuecomment-1823560428
## Migration Guide
This PR should have one.
# Objective
- Finish the work done in #8942 .
## Solution
- Rebase the changes made in #8942 and fix the issues stopping it from
being merged earlier

# Objective
`update_accessibility_nodes` is one of the most nested functions in the
entire Bevy repository, with a maximum of 9 levels of indentations. This
PR refactors it down to 3 levels of indentations, while improving
readability on other fronts. The result is a function that is actually
understandable at a first glance.
- This is a proof of concept to demonstrate that it is possible to
gradually lower the nesting limit proposed by #10896.
PS: I read AccessKit's documentation, but I don't have experience with
it. Therefore, naming of variables and subroutines may be a bit off.
PS2: I don't know if the test suite covers the functionality of this
system, but since I've spent quite some time on it and the changes were
simple, I'm pretty confident the refactor is functionally equivalent to
the original.
## Solution
I documented each change with a commit, but as a summary I did the
following to reduce nesting:
- I moved from `if-let` blocks to `let-else` statements where
appropriate to reduce rightward shift
- I extracted the closure body to a new function `update_adapter`
- I factored out parts of `update_adapter` into new functions
`queue_node_for_update` and `add_children_nodes`
**Note for reviewers:** GitHub's diff viewer is not the greatest in
showing horizontal code shifts, therefore you may want to use a
different tool like VSCode to review some commits, especially the second
one (anyway, that commit is very straightforward, despite changing many
lines).
# Objective
- Shorten paths by removing unnecessary prefixes
## Solution
- Remove the prefixes from many paths which do not need them. Finding
the paths was done automatically using built-in refactoring tools in
Jetbrains RustRover.
forward for bevy user to consume
# Objective
- since winit 0.27 an event WindowOccluded will be produced:
https://docs.rs/winit/latest/winit/event/enum.WindowEvent.html#variant.Occluded
- on ios this is currently the only way to know if an app comes back
from the background which is an important time to to things (like
resetting the badge)
## Solution
- pick up the winit event and forward it to a new `EventWriter`
---
## Changelog
### Added
- new Event `WindowOccluded` added allowing to hook into
`WindowEvent::Occluded` of winit
# Objective
- Window size, scale and position are not correct on the first execution
of the systems
- Fixes#10407, fixes#10642
## Solution
- Don't run `update` before we get a chance to create the window in
winit
- Finish reverting #9826 after #10389
# Objective
- Standardize fmt for toml files
## Solution
- Add [taplo](https://taplo.tamasfe.dev/) to CI (check for fmt and diff
for toml files), for context taplo is used by the most popular extension
in VScode [Even Better
TOML](https://marketplace.visualstudio.com/items?itemName=tamasfe.even-better-toml
- Add contribution section to explain toml fmt with taplo.
Now to pass CI you need to run `taplo fmt --option indent_string=" "` or
if you use vscode have the `Even Better TOML` extension with 4 spaces
for indent

# Objective
- Fix adding `#![allow(clippy::type_complexity)]` everywhere. like #9796
## Solution
- Use the new [lints] table that will land in 1.74
(https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#lints)
- inherit lint to the workspace, crates and examples.
```
[lints]
workspace = true
```
## Changelog
- Bump rust version to 1.74
- Enable lints table for the workspace
```toml
[workspace.lints.clippy]
type_complexity = "allow"
```
- Allow type complexity for all crates and examples
```toml
[lints]
workspace = true
```

# Objective
The way `bevy_app` works was changed unnecessarily in #9826 whose
changes should have been specific to `bevy_winit`.
I'm somewhat disappointed that happened and we can see in
https://github.com/bevyengine/bevy/pull/10195 that it made things more
complicated.
Even worse, in #10385 it's clear that this breaks the clean abstraction
over another engine someone built with Bevy!
Fixes#10385.
## Solution
- Move the changes made to `bevy_app` in #9826 to `bevy_winit`
- Revert the changes to `ScheduleRunnerPlugin` and the `run_once` runner
in #10195 as they're no longer necessary.
While this code is breaking relative to `0.12.0`, it reverts the
behavior of `bevy_app` back to how it was in `0.11`.
Due to the nature of the breakage relative to `0.11` I hope this will be
considered for `0.12.1`.
# Objective
- Fixes#10532
## Solution
I've updated the various `Event` send methods to return the sent
`EventId`(s). Since these methods previously returned nothing, and this
information is cheap to copy, there should be minimal negative
consequences to providing this additional information. In the case of
`send_batch`, an iterator is returned built from `Range` and `Map`,
which only consumes 16 bytes on the stack with no heap allocations for
all batch sizes. As such, the cost of this information is negligible.
These changes are reflected for `EventWriter` and `World`. For `World`,
the return types are optional to account for the possible lack of an
`Events` resource. Again, these methods previously returned no
information, so its inclusion should only be a benefit.
## Usage
Now when sending events, the IDs of those events is available for
immediate use:
```rust
// Example of a request-response system where the requester can track handled requests.
/// A system which can make and track requests
fn requester(
mut requests: EventWriter<Request>,
mut handled: EventReader<Handled>,
mut pending: Local<HashSet<EventId<Request>>>,
) {
// Check status of previous requests
for Handled(id) in handled.read() {
pending.remove(&id);
}
if !pending.is_empty() {
error!("Not all my requests were handled on the previous frame!");
pending.clear();
}
// Send a new request and remember its ID for later
let request_id = requests.send(Request::MyRequest { /* ... */ });
pending.insert(request_id);
}
/// A system which handles requests
fn responder(
mut requests: EventReader<Request>,
mut handled: EventWriter<Handled>,
) {
for (request, id) in requests.read_with_id() {
if handle(request).is_ok() {
handled.send(Handled(id));
}
}
}
```
In the above example, a `requester` system can send request events, and
keep track of which ones are currently pending by `EventId`. Then, a
`responder` system can act on that event, providing the ID as a
reference that the `requester` can use. Before this PR, it was not
trivial for a system sending events to keep track of events by ID. This
is unfortunate, since for a system reading events, it is trivial to
access the ID of a event.
---
## Changelog
- Updated `Events`:
- Added `send_batch`
- Modified `send` to return the sent `EventId`
- Modified `send_default` to return the sent `EventId`
- Updated `EventWriter`
- Modified `send_batch` to return all sent `EventId`s
- Modified `send` to return the sent `EventId`
- Modified `send_default` to return the sent `EventId`
- Updated `World`
- Modified `send_event` to return the sent `EventId` if sent, otherwise
`None`.
- Modified `send_event_default` to return the sent `EventId` if sent,
otherwise `None`.
- Modified `send_event_batch` to return all sent `EventId`s if sent,
otherwise `None`.
- Added unit test `test_send_events_ids` to ensure returned `EventId`s
match the sent `Event`s
- Updated uses of modified methods.
## Migration Guide
### `send` / `send_default` / `send_batch`
For the following methods:
- `Events::send`
- `Events::send_default`
- `Events::send_batch`
- `EventWriter::send`
- `EventWriter::send_default`
- `EventWriter::send_batch`
- `World::send_event`
- `World::send_event_default`
- `World::send_event_batch`
Ensure calls to these methods either handle the returned value, or
suppress the result with `;`.
```rust
// Now fails to compile due to mismatched return type
fn send_my_event(mut events: EventWriter<MyEvent>) {
events.send_default()
}
// Fix
fn send_my_event(mut events: EventWriter<MyEvent>) {
events.send_default();
}
```
This will most likely be noticed within `match` statements:
```rust
// Before
match is_pressed {
true => events.send(PlayerAction::Fire),
// ^--^ No longer returns ()
false => {}
}
// After
match is_pressed {
true => {
events.send(PlayerAction::Fire);
},
false => {}
}
```
