# 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
---------

# 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
---------

# 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.
### Notes to reviewers

## Changelog
* `bevy:🪟:WindowMoved`'s `entity` field has been renamed to
`window`
## 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:
```diff
-window_moved.entity
+window_moved.window
```

# 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:
https://github.com/gfx-rs/wgpu/blob/trunk/CHANGELOG.md

# 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
Consider enable the non-whitespace diff to see the _real_ change set.
# Objective
- Since #10911, example `button` crashes when clicking the button

## 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

# 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
- 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 => {}
}
```

- Handle pausing audio when Android app is suspended
## Solution
- This is the start of application lifetime events. They are mostly
useful on mobile
- Next version of winit should add a few more
- When application is suspended, send an event to notify the
application, and run the schedule one last time before actually
suspending the app

## Solution
- Expose a more complex state of an app than just "ready"
- Also block adding plugins to an app after it has finished or cleaned
up its plugins as that wouldn't work anyway
## Migration Guide
* `app.ready()` has been replaced by `app.plugins_state()` which will
return more details on the current state of plugins in the app
# Objective
This PR addresses the issue where Bevy displays one or several black
frames before the scene is first rendered. This is particularly
noticeable on iOS, where the black frames disrupt the transition from
the launch screen to the game UI. I have written about my search to
solve this issue on the Bevy discord:
https://discord.com/channels/691052431525675048/1151047604520632352
While I can attest this PR works on both iOS and Linux/Wayland (and even
seems to resolve a slight flicker during startup with the latter as
well), I'm not familiar enough with Bevy to judge the full implications
of these changes. I hope a reviewer or tester can help me confirm
whether this is the right approach, or what might be a cleaner solution
to resolve this issue.
## Solution
I have moved the "startup phase" as well as the plugin finalization into
the `app.run()` function so those things finish synchronously before the
"main schedule" starts. I even move one frame forward as well, using
`app.update()`, to make sure the rendering has caught up with the state
of the finalized plugins as well.
I admit that part of this was achieved through trial-and-error, since
not doing the "startup phase" *before* `app.finish()` resulted in
panics, while not calling an extra `app.update()` didn't fully resolve
the issue.
What I *can* say, is that the iOS launch screen animation works in such
a way that the OS initiates the transition once the framework's
[`didFinishLaunching()`](https://developer.apple.com/documentation/uikit/uiapplicationdelegate/1622921-application)
returns, meaning app developers **must** finish setting up their UI
before that function returns. This is what basically led me on the path
to try to "finish stuff earlier" :)
## Changelog
### Changed
- The startup phase and the first frame are rendered synchronously when
calling `app.run()`, before the "main schedule" is started. This fixes
black frames during the iOS launch transition and possible flickering on
other platforms, but may affect initialization order in your
application.
## Migration Guide
Because of this change, the timing of the first few frames might have
changed, and I think it could be that some things one may expect to be
initialized in a system may no longer be. To be honest, I feel out of my
depth to judge the exact impact here.
# Objective
Allow Bevy apps to run without requiring to start from the main thread.
This allows other projects and applications to do things like spawning a
normal or scoped
thread and run Bevy applications there.
The current behaviour if you try this is a panic.
## Solution
Allow this by default on platforms winit supports this behaviour on
(x11, Wayland, Windows).

### Added
- Added the ability to start Bevy apps outside of the main thread on

# Objective
`bevy_a11y` was impossible to integrate into some third-party projects
in part because it insisted on managing the accessibility tree on its
own.
## Solution
The changes in this PR were necessary to get `bevy_egui` working with
Bevy's AccessKit integration. They were tested on a fork of 0.11,
developed against `bevy_egui`, then ported to main and tested against
the `ui` example.
## Changelog
### Changed
* Add `bevy_a11y::ManageAccessibilityUpdates` to indicate whether the
ECS should manage accessibility tree updates.
* Add getter/setter to `bevy_a11y::AccessibilityRequested`.
* Add `bevy_a11y::AccessibilitySystem` `SystemSet` for ordering relative
to accessibility tree updates.
* Upgrade `accesskit` to v0.12.0.
### Fixed
* Correctly set initial accessibility focus to new windows on creation.
## Migration Guide
### Change direct accesses of `AccessibilityRequested` to use
`AccessibilityRequested.::get()`/`AccessibilityRequested::set()`

```
use std::sync::atomic::Ordering;

# Objective
Improve compatibility with macOS Sonoma and Xcode 15.0.
## Solution
- Adds the workaround by @ptxmac to ignore the invalid window sizes
provided by `winit` on macOS 14.0
- This still provides a slightly wrong content size when resizing (it
fails to account for the window title bar, so some content gets clipped
at the bottom) but it's _much better_ than crashing.
- Adds docs on how to work around the `bindgen` bug on Xcode 15.0.

fixing this did produce a lot of the "symbol soup" mentioned, e.g. `for

# Objective
- When spawning a window, it will be white until the GPU is ready to
draw the app. To avoid this, we can make the window invisible and then
make it visible once the gpu is ready. Unfortunately, the visible flag
is not available to users.
## Solution
- Let users change the visible flag
## Notes
This is only user controlled. It would be nice if it was done
automatically by bevy instead but I want to keep this PR simple.
# Objective
Fixes#9455
This change has probably been forgotten in
https://github.com/bevyengine/bevy/pull/8306.
## Solution
Remove the inversion of the Y axis when propagates window change back to
winit.
Fixes#5856. Fixes#8080. Fixes#9040.
# Objective
We need to limit the update rate of games whose windows are not visible
(minimized or completely occluded). Compositors typically ignore the
VSync settings of windows that aren't visible. That, combined with the
lack of rendering work, results in a scenario where an app becomes
completely CPU-bound and starts updating without limit.
There are currently three update modes.
- `Continuous` updates an app as often as possible.
- `Reactive` updates when new window or device events have appeared, a
timer expires, or a redraw is requested.
- `ReactiveLowPower` is the same as `Reactive` except it ignores device
events (e.g. general mouse movement).
The problem is that the default "game" settings are set to `Contiuous`
even when no windows are visible.
### More Context
- https://github.com/libsdl-org/SDL/issues/1871
- https://github.com/glfw/glfw/issues/680
- https://github.com/godotengine/godot/issues/19741
- https://github.com/godotengine/godot/issues/64708
## Solution
Change the default "unfocused" `UpdateMode` for games to
`ReactiveLowPower` just like desktop apps. This way, even when the
window is occluded, the app still updates at a sensible rate or if
something about the window changes. I chose 20Hz arbitrarily.
Redo of #7590 since I messed up my branch.
# Objective

users can enable or disable specific window control buttons.
---
## Changelog
- Added an `enabled_buttons` member to the `Window` struct through which
users can enable or disable specific window control buttons.
- Added a new system to the `window_settings` example which demonstrates
the toggling functionality.

# Objective
I'm creating an iOS game and had to find a way to persist game state
when the application is terminated. This required listening to the
[`applicationWillTerminate()`
method](https://developer.apple.com/documentation/uikit/uiapplicationdelegate/1623111-applicationwillterminate),
but I cannot do so myself anymore since `winit` already set up a
delegate to listen for it, and there can be only one delegate.
So I had to move up the stack and try to respond to one of the events
from `winit` instead. It appears `winit` fires two events that could
serve my purpose: `WindowEvent::Destroyed` and `Event::LoopDestroyed`.
It seemed to me the former might be slightly more generally useful, and
I also found a past discussion that suggested it would be appropriate
for Bevy to have a `WindowDestroyed` event:
https://github.com/bevyengine/bevy/pull/5589#discussion_r942811021
## Solution
- I've added the `WindowDestroyed` event, which fires when `winit` fires
`WindowEvent::Destroyed`.
---
## Changelog
### Added
- Introduced a new `WindowDestroyed` event type. It is used to indicate
a window has been destroyed by the windowing system.
# Objective
- Better consistency with `add_systems`.
- Deprecating `add_plugin` in favor of a more powerful `add_plugins`.
- Allow passing `Plugin` to `add_plugins`.
- Allow passing tuples to `add_plugins`.
## Solution
- `App::add_plugins` now takes an `impl Plugins` parameter.
- `App::add_plugin` is deprecated.
- `Plugins` is a new sealed trait that is only implemented for `Plugin`,
`PluginGroup` and tuples over `Plugins`.
- All examples, benchmarks and tests are changed to use `add_plugins`,
using tuples where appropriate.
---
## Changelog
### Changed
- `App::add_plugins` now accepts all types that implement `Plugins`,
which is implemented for:
- Types that implement `Plugin`.
- Types that implement `PluginGroup`.
- Tuples (up to 16 elements) over types that implement `Plugins`.
- Deprecated `App::add_plugin` in favor of `App::add_plugins`.
## Migration Guide
- Replace `app.add_plugin(plugin)` calls with `app.add_plugins(plugin)`.

# Objective
- Document android code that is currently causing clippy warnings due to
not being documented
## Solution
- Document the two previously undocumented items
# Objective
The goal of this PR is to receive touchpad magnification and rotation
events.
## Solution
Implement pendants for winit's `TouchpadMagnify` and `TouchpadRotate`
events.
Adjust the `mouse_input_events.rs` example to debug magnify and rotate
events.
Since winit only reports these events on macOS, the Bevy events for
touchpad magnification and rotation are currently only fired on macOS.
# Objective
Be consistent with `Resource`s and `Components` and have `Event` types
be more self-documenting.
Although not susceptible to accidentally using a function instead of a
value due to `Event`s only being initialized by their type, much of the
same reasoning for removing the blanket impl on `Resource` also applies
here.
* Not immediately obvious if a type is intended to be an event
* Prevent invisible conflicts if the same third-party or primitive types
are used as events
* Allows for further extensions (e.g. opt-in warning for missed events)
## Solution
Remove the blanket impl for the `Event` trait. Add a derive macro for
it.
---
## Changelog
- `Event` is no longer implemented for all applicable types. Add the
`#[derive(Event)]` macro for events.
## Migration Guide
* Add the `#[derive(Event)]` macro for events. Third-party types used as
events should be wrapped in a newtype.
# Objective
- Fixes https://github.com/bevyengine/bevy/issues/8586.
## Solution
- Add `preferred_theme` field to `Window` and set it when window
creation
- Add `window_theme` field to `InternalWindowState` to store current
window theme
- Expose winit `WindowThemeChanged` event

# Objective
- Support WebGPU
- alternative to #5027 that doesn't need any async / await
- fixes#8315
- Surprise fix#7318
## Solution
### For async renderer initialisation
- Update the plugin lifecycle:
- app builds the plugin
- calls `plugin.build`
- registers the plugin
- app starts the event loop
- event loop waits for `ready` of all registered plugins in the same
order
- returns `true` by default
- then call all `finish` then all `cleanup` in the same order as
registered
- then execute the schedule
In the case of the renderer, to avoid anything async:
- building the renderer plugin creates a detached task that will send
back the initialised renderer through a mutex in a resource
- `ready` will wait for the renderer to be present in the resource
- `finish` will take that renderer and place it in the expected
resources by other plugins
- other plugins (that expect the renderer to be available) `finish` are
called and they are able to set up their pipelines
- `cleanup` is called, only custom one is still for pipeline rendering
### For WebGPU support
- update the `build-wasm-example` script to support passing `--api
webgpu` that will build the example with WebGPU support
- feature for webgl2 was always enabled when building for wasm. it's now
in the default feature list and enabled on all platforms, so check for
this feature must also check that the target_arch is `wasm32`
---
## Migration Guide
- `Plugin::setup` has been renamed `Plugin::cleanup`
- `Plugin::finish` has been added, and plugins adding pipelines should
do it in this function instead of `Plugin::build`
```rust
// Before
impl Plugin for MyPlugin {
fn build(&self, app: &mut App) {
app.insert_resource::<MyResource>
.add_systems(Update, my_system);
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<RenderResourceNeedingDevice>()
.init_resource::<OtherRenderResource>();
}
}
// After
impl Plugin for MyPlugin {
fn build(&self, app: &mut App) {
app.insert_resource::<MyResource>
.add_systems(Update, my_system);
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<OtherRenderResource>();
}
fn finish(&self, app: &mut App) {
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<RenderResourceNeedingDevice>();
}
}
```
Links in the api docs are nice. I noticed that there were several places
where structs / functions and other things were referenced in the docs,
but weren't linked. I added the links where possible / logical.

# Objective
The clippy lint `type_complexity` is known not to play well with bevy.
It frequently triggers when writing complex queries, and taking the
lint's advice of using a type alias almost always just obfuscates the
code with no benefit. Because of this, this lint is currently ignored in
CI, but unfortunately it still shows up when viewing bevy code in an
IDE.
As someone who's made a fair amount of pull requests to this repo, I
will say that this issue has been a consistent thorn in my side. Since
bevy code is filled with spurious, ignorable warnings, it can be very
difficult to spot the *real* warnings that must be fixed -- most of the
time I just ignore all warnings, only to later find out that one of them
was real after I'm done when CI runs.
## Solution
Suppress this lint in all bevy crates. This was previously attempted in
#7050, but the review process ended up making it more complicated than
it needs to be and landed on a subpar solution.
The discussion in https://github.com/rust-lang/rust-clippy/pull/10571
explores some better long-term solutions to this problem. Since there is
no timeline on when these solutions may land, we should resolve this
issue in the meantime by locally suppressing these lints.
### Unresolved issues
Currently, these lints are not suppressed in our examples, since that
would require suppressing the lint in every single source file. They are
still ignored in CI.
# Objective
Make the coordinate systems of screen-space items (cursor position, UI,
viewports, etc.) consistent.
## Solution
Remove the weird double inversion of the cursor position's Y origin.
Once in bevy_winit to the bottom and then again in bevy_ui back to the
top.
This leaves the origin at the top left like it is in every other popular
app framework.
Update the `world_to_viewport`, `viewport_to_world`, and
`viewport_to_world_2d` methods to flip the Y origin (as they should
since the viewport coordinates were always relative to the top left).
## Migration Guide
`Window::cursor_position` now returns the position of the cursor
relative to the top left instead of the bottom left.
This now matches other screen-space coordinates like
`RelativeCursorPosition`, UI, and viewports.
The `world_to_viewport`, `viewport_to_world`, and `viewport_to_world_2d`
methods on `Camera` now return/take the viewport position relative to
the top left instead of the bottom left.
If you were using `world_to_viewport` to position a UI node the returned
`y` value should now be passed into the `top` field on `Style` instead
of the `bottom` field.
Note that this might shift the position of the UI node as it is now
anchored at the top.
If you were passing `Window::cursor_position` to `viewport_to_world` or
`viewport_to_world_2d` no change is necessary.
# Objective
In the
[`Text`](3442a13d2c/crates/bevy_text/src/text.rs (L18))
struct the field is named: `linebreak_behaviour`, the British spelling
of _behavior_.
**Update**, also found:
- `FileDragAndDrop::HoveredFileCancelled`
- `TouchPhase::Cancelled`
- `Touches.just_cancelled`
The majority of all spelling is in the US but when you have a lot of
contributors across the world, sometimes
spelling differences can pop up in APIs such as in this case.
For consistency, I think it would be worth a while to ensure that the
API is persistent.
Some examples:
`from_reflect.rs` has `DefaultBehavior`
TextStyle has `color` and uses the `Color` struct.
In `bevy_input/src/Touch.rs` `TouchPhase::Cancelled` and _canceled_ are
used interchangeably in the documentation
I've found that there is also the same type of discrepancies in the
documentation, though this is a low priority but is worth checking.
**Update**: I've now checked the documentation (See #8291)
## Solution
I've only renamed the inconsistencies that have breaking changes and
documentation pertaining to them. The rest of the documentation will be
changed via #8291.
Do note that the winit API is written with UK spelling, thus this may be
a cause for confusion:
`winit::event::TouchPhase::Cancelled => TouchPhase::Canceled`
`winit::event::WindowEvent::HoveredFileCancelled` -> Related to
`FileDragAndDrop::HoveredFileCanceled`
But I'm hoping to maybe outline other spelling inconsistencies in the
API, and maybe an addition to the contribution guide.
---
## Changelog
- `Text` field `linebreak_behaviour` has been renamed to
`linebreak_behavior`.
- Event `FileDragAndDrop::HoveredFileCancelled` has been renamed to
`HoveredFileCanceled`
- Function `Touches.just_cancelled` has been renamed to
`Touches.just_canceled`
- Event `TouchPhase::Cancelled` has been renamed to
`TouchPhase::Canceled`
## Migration Guide
Update where `linebreak_behaviour` is used to `linebreak_behavior`
Updated the event `FileDragAndDrop::HoveredFileCancelled` where used to
`HoveredFileCanceled`
Update `Touches.just_cancelled` where used as `Touches.just_canceled`
The event `TouchPhase::Cancelled` is now called `TouchPhase::Canceled`
# Objective
Documentation should no longer be using pre-stageless terminology to
avoid confusion.
## Solution
- update all docs referring to stages to instead refer to sets/schedules
where appropriate
- also mention `apply_system_buffers` for anything system-buffer-related
that previously referred to buffers being applied "at the end of a
stage"
