# Objective
Gamepad / directional navigation needs an example, for both teaching and
testing purposes.
## Solution
- Add a simple grid-based example.
- Fix an intermittent panic caused by a race condition with bevy_a11y
- Clean up small issues noticed in bevy_input_focus
## To do: this PR
- [x] figure out why "enter" isn't doing anything
- [x] change button color on interaction rather than printing
- [x] add on-screen directions
- [x] move to an asymmetric grid to catch bugs
- [x] ~~fix colors not resetting on button press~~ lol this is mostly
just a problem with hacking `Interaction` for this
- [x] swap to using observers + bubbling, rather than `Interaction`
## To do: future work
- when I increase the button size, such that there is no line break, the
text on the buttons is no longer centered :( EDIT: this is
https://github.com/bevyengine/bevy/issues/16783
- add gamepad stick navigation
- add tools to find the nearest populated quadrant to make diagonal
inputs work
- add a `add_edges` method to `DirectionalNavigationMap`
- add a `add_grid` method to `DirectionalNavigationMap`
- make the example's layout more complex and realistic
- add tools to automatically generate this list
- add button shake on failed navigation rather than printing an error
- make Pressed events easier to mock: default fields, PointerId::Focus
## Testing
`cargo run --example directional_navigation`

# Objective
Many instances of `clippy::too_many_arguments` linting happen to be on
systems - functions which we don't call manually, and thus there's not
much reason to worry about the argument count.
## Solution
Allow `clippy::too_many_arguments` globally, and remove all lint
attributes related to it.
# Objective
- https://github.com/bevyengine/bevy/issues/17111
## Solution
Set the `clippy::allow_attributes` and
`clippy::allow_attributes_without_reason` lints to `deny`, and bring
`bevy_winit` in line with the new restrictions.
## Testing
`cargo clippy --tests` was run, and no errors were encountered.

# Objective
- Fixes#12562
- Fixes#12195
## Solution
- Use `spawn_app` instead of `run_app` for web platform in
`winit_runner` as suggested in the
[document](https://docs.rs/winit/latest/winit/platform/web/trait.EventLoopExtWebSys.html#tymethod.spawn_app)
## Testing
- Did you test these changes? If so, how?
Tested on web. Created a react app which renders the bevy WASM app and
returns the disposer to JS. Js will call the disposer on component
unmount to stop the app, the disposer sends a signal to a `signal`
receiver in rust which exits the app like this:
```rust
fn handle_stop_signal(
signal: NonSendMut<StopSignalReceiver>,
window_entities: Query<(Entity, &Window)>,
mut event_writer: EventWriter<WindowCloseRequested>,
) {
if let Ok(_) = signal.try_recv() {
for (entity, _window) in window_entities.iter() {
info!("closing window entity: {:x}", entity.to_bits());
event_writer.send(WindowCloseRequested { window: entity });
}
}
}
```
- Are there any parts that need more testing?
- No
- How can other people (reviewers) test your changes? Is there anything
specific they need to know?
- Are all resources released after stopping the app like this? The WASM
is still loaded, the LogPlugin complains on the logger
re-initialization, but it's a warning anyway.
- If relevant, what platforms did you test these changes on, and are
there any important ones you can't test?
- Tested the WASM version on web platform and the native version on
MacOS.

# Objective
- I want to hide the clock and the battery indicator on iOS
## Solution
- Add the platform specific property `prefers_status_bar_hidden` on
Window creation, and map it to `with_prefers_status_bar_hidden` in
winit.
## Testing
- Tested on iOS

# Objective
- Contributes to #11478
## Solution
- Made `bevy_utils::tracing` `doc(hidden)`
- Re-exported `tracing` from `bevy_log` for end-users
- Added `tracing` directly to crates that need it.
## Testing
- CI
---
## Migration Guide
If you were importing `tracing` via `bevy::utils::tracing`, instead use
`bevy::log::tracing`. Note that many items within `tracing` are also
directly re-exported from `bevy::log` as well, so you may only need
`bevy::log` for the most common items (e.g., `warn!`, `trace!`, etc.).
This also applies to the `log_once!` family of macros.
## Notes
- While this doesn't reduce the line-count in `bevy_utils`, it further
decouples the internal crates from `bevy_utils`, making its eventual
removal more feasible in the future.
- I have just imported `tracing` as we do for all dependencies. However,
a workspace dependency may be more appropriate for version management.
# Objective
- Contributes to #11478
- Contributes to #16877
## Solution
- Removed everything except `Instant` from `bevy_utils::time`
## Testing
- CI
---
## Migration Guide
If you relied on any of the following from `bevy_utils::time`:
- `Duration`
- `TryFromFloatSecsError`
Import these directly from `core::time` regardless of platform target
(WASM, mobile, etc.)
If you relied on any of the following from `bevy_utils::time`:
- `SystemTime`
- `SystemTimeError`
Instead import these directly from either `std::time` or `web_time` as
appropriate for your target platform.
## Notes
`Duration` and `TryFromFloatSecsError` are both re-exports from
`core::time` regardless of whether they are used from `web_time` or
`std::time`, so there is no value gained from re-exporting them from
`bevy_utils::time` as well. As for `SystemTime` and `SystemTimeError`,
no Bevy internal crates or examples rely on these types. Since Bevy
doesn't have a `Time<Wall>` resource for interacting with wall-time (and
likely shouldn't need one), I think removing these from `bevy_utils`
entirely and waiting for a use-case to justify inclusion is a reasonable
path forward.
# Objective
Some sort calls and `Ord` impls are unnecessarily complex.
## Solution
Rewrite the "match on cmp, if equal do another cmp" as either a
comparison on tuples, or `Ordering::then_with`, depending on whether the
compare keys need construction.
`sort_by` -> `sort_by_key` when symmetrical. Do the same for
`min_by`/`max_by`.
Note that `total_cmp` can only work with `sort_by`, and not on tuples.
When sorting collected query results that contain
`Entity`/`MainEntity`/`RenderEntity` in their `QueryData`, with that
`Entity` in the sort key:
stable -> unstable sort (all queried entities are unique)
If key construction is not simple, switch to `sort_by_cached_key` when
possible.
Sorts that are only performed to discover the maximal element are
replaced by `max_by_key`.
Dedicated comparison functions and structs are removed where simple.
Derive `PartialOrd`/`Ord` when useful.
Misc. closure style inconsistencies.
## Testing
- Existing tests.
# Objective
Fixes#16104
## Solution
I removed all instances of `:?` and put them back one by one where it
caused an error.
I removed some bevy_utils helper functions that were only used in 2
places and don't add value. See: #11478
## Testing
CI should catch the mistakes
## Migration Guide
`bevy::utils::{dbg,info,warn,error}` were removed. Use
`bevy::utils::tracing::{debug,info,warn,error}` instead.

# Objective
Bevy now has first-class input focus handling! We should use this for
accessibility purpose via accesskit too.
## Solution
- Removed bevy_a11y::Focus.
- Replaced all usages of Focus with InputFocus
- Changed the dependency tree so bevy_a11y relies on bevy_input_focus
- Moved initialization of the focus (starts with the primary window)
from bevy_window to bevy_input_focus to avoid circular dependencies (and
it's cleaner)
## Testing
TODO
## Migration Guide
`bevy_a11y::Focus` has been replaced with `bevy_input_focus::Focus`.
# Objective
Allow handling of dead keys on some keyboard layouts.
In some cases, dead keys were impossible to get using the
`KeyboardInput` event. This information is already present in the
underlying winit `KeyEvent`, but it wasn't exposed.
## Solution
Expose the `text` field from winit's `KeyEvent` in `KeyboardInput`.
This logic is inspired egui's implementation here:
adfc0bebfc/crates/egui-winit/src/lib.rs (L790-L807)
## Testing
This is a new field, so it shouldn't break any existing functionality. I
tested that this change works by running the modified `text_input`
example on different keyboard layouts.
## Example
Using a Portuguese/ABNT2 keyboard layout on windows and pressing
<kbd>\~</kbd> followed by
<kbd>a</kbd>/<kbd>Space</kbd>/<kbd>d</kbd>/<kbd>\~</kbd> now generates
the following events:
```
KeyboardInput { key_code: Quote, logical_key: Dead(Some('~')), state: Pressed, text: None, repeat: false, window: 0v1#4294967296 }
KeyboardInput { key_code: KeyA, logical_key: Character("ã"), state: Pressed, text: Some("ã"), repeat: false, window: 0v1#4294967296 }
KeyboardInput { key_code: Quote, logical_key: Dead(Some('~')), state: Pressed, text: None, repeat: false, window: 0v1#4294967296 }
KeyboardInput { key_code: Space, logical_key: Space, state: Pressed, text: Some("~"), repeat: false, window: 0v1#4294967296 }
KeyboardInput { key_code: Quote, logical_key: Dead(Some('~')), state: Pressed, text: None, repeat: false, window: 0v1#4294967296 }
KeyboardInput { key_code: KeyD, logical_key: Character("d"), state: Pressed, text: Some("~d"), repeat: false, window: 0v1#4294967296 }
KeyboardInput { key_code: Quote, logical_key: Dead(Some('~')), state: Pressed, text: None, repeat: false, window: 0v1#4294967296 }
KeyboardInput { key_code: Quote, logical_key: Dead(Some('~')), state: Pressed, text: Some("~~"), repeat: false, window: 0v1#4294967296 }
```
The logic for getting an input is pretty simple: check if `text` is
`Some`. If it is, this is actual input text, otherwise it isn't.
There's a small caveat: certain keys generate control characters in the
input text, which needs to be filtered out:
```
KeyboardInput { key_code: Escape, logical_key: Escape, state: Pressed, text: Some("\u{1b}"), repeat: false, window: 0v1#4294967296 }
```
I've updated the text_input example to include egui's solution to this,
which works well.
## Migration Guide
The `KeyboardInput` event now has a new `text` field.
# Objective
- A `Trigger` has multiple associated `Entity`s - the entity observing
the event, and the entity that was targeted by the event.
- The field `entity: Entity` encodes no semantic information about what
the entity is used for, you can already tell that it's an `Entity` by
the type signature!
## Solution
- Rename `trigger.entity()` to `trigger.target()`
---
## Changelog
- `Trigger`s are associated with multiple entities. `Trigger::entity()`
has been renamed to `Trigger::target()` to reflect the semantics of the
entity being returned.
## Migration Guide
- Rename `Trigger::entity()` to `Trigger::target()`.
- Rename `ObserverTrigger::entity` to `ObserverTrigger::target`
# Objective
- Exposes raw winit events making Bevy even more modular and powerful
for custom plugin developers (e.g. a custom render plugin).
XRef: https://github.com/bevyengine/bevy/issues/5977
It doesn't quite close the issue as sending events is not supported (or
not very useful to be precise). I would think that supporting that
requires some extra considerations by someone a bit more familiar with
the `bevy_winit` crate. That said, this PR could be a nice step forward.
## Solution
Emit `RawWinitWindowEvent` objects for each received event.
## Testing
I verified that the events are emitted using a basic test app. I don't
think it makes sense to solidify this behavior in one of the examples.
---
## Showcase
My example usage for a custom `egui_winit` integration:
```rust
for ev in winit_events.read() {
if ev.window_id == window.id {
let _ = egui_winit.on_window_event(&window, &ev.event);
}
}
```

# Objective
- Avoid recreating the monitor every loop (temp fix until it's done
properly on winit side)
- Add a new `WinitSettings` preset for mobile that makes the winit loop
wait more and recommend its usage
# Objective
- Currently when you attempt to change the cursor_grab_mode it caches
the new value whether the cursor grab succeeded or failed. This change
handles the Result being returned by set_cursor_grab and changes the
cursor_grab_mode back to the cached version in case of an Error.
- Creates a way to handle #16237 and #16238
## Solution
- I changed the signature of winit_windows attempt_grab to return the
Result<(), ExternalError> that winit set_cursor_grab returns. The system
that calls attempt_grab now checks if there's an error returned, and if
there is it sets the grab_mode back to the cached version (similar to
what hit_test does a few lines down).
## Testing
- I tested using this system that previously would not correctly lock
the mouse on Ubuntu/x11
```
pub fn lock_mouse(mut primary_window: Query<&mut Window, With<PrimaryWindow>>) {
let window = &mut primary_window.single_mut();
if window.focused {
window.cursor_options.grab_mode = CursorGrabMode::Confined;
} else {
window.cursor_options.grab_mode = CursorGrabMode::None;
}
}
```
- I only tested on Ubuntu with x11
# Objective
- Fixes#16235
## Solution
- Both Bevy and AccessKit export a `Node` struct, to reduce confusion
Bevy will no longer re-export `AccessKit` from `bevy_a11y`
## Testing
- Tested locally
## Migration Guide
```diff
# main.rs
-- use bevy_a11y::{
-- accesskit::{Node, Rect, Role},
-- AccessibilityNode,
-- };
++ use bevy_a11y::AccessibilityNode;
++ use accesskit::{Node, Rect, Role};
# Cargo.toml
++ accesskit = "0.17"
```
- Users will need to add `accesskit = "0.17"` to the dependencies
section of their `Cargo.toml` file and update their `accesskit` use
statements to come directly from the external crate instead of
`bevy_a11y`.
- Make sure to keep the versions of `accesskit` aligned with the
versions Bevy uses.
# Objective
- Fixes#16254
- fix building in wasm without custom_cursor
## Solution
- Properly flag `CustomCursor::Url` which only exist in wasm, but also
only when `custom_cursor` is enabled
## Testing
- `cargo check --target wasm32-unknown-unknown -p bevy_winit`
# Objective
- Bumps accesskit and accesskit_winit dependencies
## Solution
- Fixes several breaking API changes introduced in accesskit 0.23.
## Testing
- Tested with the ui example and seems to work comparably
# Objective
Currently there's no way to change the window's cursor icon with the
`custom_cursor` feature **disabled**. You should still be able to set
system cursor icons.
Connections:
- https://github.com/bevyengine/bevy/pull/15649
## Solution
Move some `custom_cursor` feature gates around, as to expose the
`CursorIcon` type again.
Note this refactoring was mainly piloted by hunting after the compiler
warnings -- I shouldn't have missed anything, but FYI.
## Testing
Disabled the `custom_cursor` feature, ran the `window_settings` example.
# Objective
- Fixes#15757
## Solution
- Add the platform specific property `prefers_home_indicator_hidden` to
bevy's Window configuration, and applying it by invoking
`with_prefers_home_indicator_hidden` in `winit`.
## Testing
- I have tested the `bevy_mobile_example` on the iOS platform.
## Showcase
- Currently, the `prefers_home_indicator_hidden` is enabled in the
bevy_mobile_example demo. You can test it with an iOS device. The home
indicator will disappear after several seconds of inactivity in the
bottom areas.

# Objective
Built-in observers & events should be `Reflect` so that components that
interact with them can be serialized in scenes. This is a similar pr to
#14259.
# Objective
Adding a `WinitPlugin` to a `MinimalPlugins` setup is a bit tricky and
confusing due to having a terrible error message and no examples in the
repo.
## Solution
Document what you need to add.
# Objective
Add an example for the new drag move and drag resize introduced by PR
#15674 and fix#15734.
## Solution
I created an example that allows the user to exercise drag move and drag
resize separately. The user can also choose what direction the resize
works in.
### Name
The example is called `window_drag_move`. Happy to have that
bikeshedded.
### Contentious Refactor?
This PR removed the `ResizeDirection` enumeration in favor of using
`CompassOctant` which had the same variants. Perhaps this is
contentious.
### Unsafe?
In PR #15674 I mentioned that `start_drag_move()` and
`start_drag_resize()`'s requirement to only be called in the presence of
a left-click looks like a compiler-unenforceable contract that can cause
intermittent panics when not observed, so perhaps the functions should
be marked them unsafe. **I have not made that change** here since I
didn't see a clear consensus on that.
## Testing
I exercised this on x86 macOS. However, winit for macOS does not support
drag resize. It reports a good error when `start_drag_resize()` is
called. I'd like to see it tested on Windows and Linux.

# Objective
- Android doesn't receive lifecycle event `Suspended` before suspension
## Solution
- Fix update triggering just after state change on android
## Testing
- Tested on the android emulator
# Objective
MacOS has some nice options for controlling the window and titlebar to
make the content appear much more "immersively" in the window. This PR
exposes options for controlling this.
## Solution
Adds new fields to `Window` to control these, with doc comments to
explain what they do and that they're MacOS only.
## Testing
Tested on a MacOS machine (not my own, I don't have one). That's where
the below screenshots were taken.
---
## Showcase
On MacOS, you now have more options for configuring the window titlebar.
You can, for example, make the title bar transparent and only show the
window controls. This provides a more "immersive" experience for your
rendered content.
Before, only this was possible:
<img width="1392" alt="image"
src="https://github.com/user-attachments/assets/abf03da2-d247-4202-a7e7-731c45d80d54">
Now, you can create windows like this:
<img width="1392" alt="image2"
src="https://github.com/user-attachments/assets/3239d0e3-4708-4798-8755-188541e14f93">
This uses the following `bevy_window::Window` settings:
```rs
fullsize_content_view: true,
titlebar_transparent: true,
titlebar_show_title: false,
```
## Migration Guide
`bevy_window::Window` now has extra fields for configuring MacOS window
settings:
```rs
pub movable_by_window_background: bool,
pub fullsize_content_view: bool,
pub has_shadow: bool,
pub titlebar_shown: bool,
pub titlebar_transparent: bool,
pub titlebar_show_title: bool,
pub titlebar_show_buttons: bool,
```
Using `Window::default` keeps the same behaviour as before.
# Objective
- Closes#15752
Calling the functions `App::observe` and `World::observe` doesn't make
sense because you're not "observing" the `App` or `World`, you're adding
an observer that listens for an event that occurs *within* the `World`.
We should rename them to better fit this.
## Solution
Renames:
- `App::observe` -> `App::add_observer`
- `World::observe` -> `World::add_observer`
- `Commands::observe` -> `Commands::add_observer`
- `EntityWorldMut::observe_entity` -> `EntityWorldMut::observe`
(Note this isn't a breaking change as the original rename was introduced
earlier this cycle.)
## Testing
Reusing current tests.
# Objective
Expose the `winit` functions
[drag_window](https://docs.rs/winit/latest/winit/window/struct.Window.html#method.drag_window)
and
[resize_window](https://docs.rs/winit/latest/winit/window/struct.Window.html#method.drag_resize_window).
Which allows implementing move & resize for windows without decorations.
## Solution
Add the functions `start_drag_move` and `start_drag_resize` to
`bevy_window::Window`, which are then assigned to fields in
`InternalWindowState`, and propagated to `winit` in the
`changed_windows` system.
## Testing
I've tested that both functions works on x11 and wayland. Not sure if
someone needs to test on windows/mac?

# Objective
- `bevy_render` should not depend on `bevy_winit`
- Fixes#15565
## Solution
- `bevy_render` no longer depends on `bevy_winit`
- The following is behind the `custom_cursor` feature
- Move custom cursor code from `bevy_render` to `bevy_winit` behind the
`custom_cursor` feature
- `bevy_winit` now depends on `bevy_render` (for `Image` and
`TextureFormat`)
- `bevy_winit` now depends on `bevy_asset` (for `Assets`, `Handle` and
`AssetId`)
- `bevy_winit` now depends on `bytemuck` (already in tree)
- Custom cursor code in `bevy_winit` reworked to use `AssetId` (other
than that it is taken over 1:1)
- Rework `bevy_winit` custom cursor interface visibility now that the
logic is all contained in `bevy_winit`
## Testing
- I ran the screenshot and window_settings examples
- Tested on linux wayland so far
---
## Migration Guide
`CursorIcon` and `CustomCursor` previously provided by
`bevy::render::view::cursor` is now available from `bevy::winit`.
A new feature `custom_cursor` enables this functionality (default
feature).
# Objective
- Remove dependency in bevy_asset to bevy_winit
- First step for #15565
## Solution
- the static `ANDROID_APP` and the `android_activity` reexport are now
in `bevy_window`
## Migration Guide
If you use the `android_activity` reexport from
`bevy::winit::android_activity`, it is now in
`bevy:🪟:android_activity`. Same for the `ANDROID_APP` static
# Objective
Add two features to switch bevy to use `NativeActivity` or
`GameActivity` on Android, use `GameActivity` by default.
Also close #12058 and probably #12026 .
## Solution
Add two features to the corresponding crates so you can toggle it, like
what `winit` and `android-activity` crate did.
---
## Changelog
Removed default `NativeActivity` feature implementation for Android,
added two new features to enable `NativeActivity` and `GameActivity`,
and use `GameActivity` by default.
## Migration Guide
Because `cargo-apk` is not compatible with `GameActivity`,
building/running using `cargo apk build/run -p bevy_mobile_example` is
no longer possible.
Users should follow the new workflow described in document.

# 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.

`#[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.

# 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

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
