# 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
Bevy seems to want to standardize on "American English" spellings. Not
sure if this is laid out anywhere in writing, but see also #15947.
While perusing the docs for `typos`, I noticed that it has a `locale`
config option and tried it out.
## Solution
Switch to `en-us` locale in the `typos` config and run `typos -w`
## Migration Guide
The following methods or fields have been renamed from `*dependants*` to
`*dependents*`.
- `ProcessorAssetInfo::dependants`
- `ProcessorAssetInfos::add_dependant`
- `ProcessorAssetInfos::non_existent_dependants`
- `AssetInfo::dependants_waiting_on_load`
- `AssetInfo::dependants_waiting_on_recursive_dep_load`
- `AssetInfos::loader_dependants`
- `AssetInfos::remove_dependants_and_labels`
# 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
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
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
- 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
- Provide a generic and _reflectable_ way to iterate over contained
entities
## Solution
Adds two new traits:
* `VisitEntities`: Reflectable iteration, accepts a closure rather than
producing an iterator. Implemented by default for `IntoIterator`
implementing types. A proc macro is also provided.
* A `Mut` variant of the above. Its derive macro uses the same field
attribute to avoid repetition.
## Testing
Added a test for `VisitEntities` that also transitively tests its derive
macro as well as the default `MapEntities` impl.
# Objective
- Fixes#6370
- Closes#6581
## Solution
- Added the following lints to the workspace:
- `std_instead_of_core`
- `std_instead_of_alloc`
- `alloc_instead_of_core`
- Used `cargo +nightly fmt` with [item level use
formatting](https://rust-lang.github.io/rustfmt/?version=v1.6.0&search=#Item%5C%3A)
to split all `use` statements into single items.
- Used `cargo clippy --workspace --all-targets --all-features --fix
--allow-dirty` to _attempt_ to resolve the new linting issues, and
intervened where the lint was unable to resolve the issue automatically
(usually due to needing an `extern crate alloc;` statement in a crate
root).
- Manually removed certain uses of `std` where negative feature gating
prevented `--all-features` from finding the offending uses.
- Used `cargo +nightly fmt` with [crate level use
formatting](https://rust-lang.github.io/rustfmt/?version=v1.6.0&search=#Crate%5C%3A)
to re-merge all `use` statements matching Bevy's previous styling.
- Manually fixed cases where the `fmt` tool could not re-merge `use`
statements due to conditional compilation attributes.
## Testing
- Ran CI locally
## Migration Guide
The MSRV is now 1.81. Please update to this version or higher.
## Notes
- This is a _massive_ change to try and push through, which is why I've
outlined the semi-automatic steps I used to create this PR, in case this
fails and someone else tries again in the future.
- Making this change has no impact on user code, but does mean Bevy
contributors will be warned to use `core` and `alloc` instead of `std`
where possible.
- This lint is a critical first step towards investigating `no_std`
options for Bevy.

# Objective
> Rust 1.81 released the #[expect(...)] attribute, which works like
#[allow(...)] but throws a warning if the lint isn't raised. This is
preferred to #[allow(...)] because it tells us when it can be removed.
- Adopts the parts of #15118 that are complete, and updates the branch
so it can be merged.
- There were a few conflicts, let me know if I misjudged any of 'em.

# Objective
- Fixes#12639.
- `ReceivedCharacter` was deprecated in #12868 for 0.14, and should be
removed for 0.15.
## Solution
- Remove all instances of `ReceivedCharacter`, including the relevant
`#[allow(deprecated)]` lint attributes.
## Migration Guide
`ReceivedCharacter` was deprecated in 0.14 due to `winit` reworking
their keyboard system. It has now been fully removed. Switch to using
`KeyboardInput` instead.
```rust
// 0.14
fn listen_characters(events: EventReader<ReceivedCharacter>) {
for event in events.read() {
info!("{}", event.char);
}
}
// 0.15
fn listen_characters(events: EventReader<KeyboardInput>) {
for event in events.read() {
// Only check for characters when the key is pressed.
if !event.state.is_pressed() {
continue;
}
// Note that some keys such as `Space` and `Tab` won't be detected as a character.
// Instead, check for them as separate enum variants.
match &event.logical_key {
Key::Character(character) => {
info!("{} pressed.", character);
},
Key::Space => {
info!("Space pressed.");
},
_ => {},
}
}
}
```
# Objective
- Crate-level prelude modules, such as `bevy_ecs::prelude`, are plagued
with inconsistency! Let's fix it!
## Solution
Format all preludes based on the following rules:
1. All preludes should have brief documentation in the format of:
> The _name_ prelude.
>
> This includes the most common types in this crate, re-exported for
your convenience.
2. All documentation should be outer, not inner. (`///` instead of
`//!`.)
3. No prelude modules should be annotated with `#[doc(hidden)]`. (Items
within them may, though I'm not sure why this was done.)
## Testing
- I manually searched for the term `mod prelude` and updated all
occurrences by hand. 🫠

# 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#14974
## Solution
- Replace all* instances of `NonZero*` with `NonZero<*>`
## Testing
- CI passed locally.
---
## Notes
Within the `bevy_reflect` implementations for `std` types,
`impl_reflect_value!()` will continue to use the type aliases instead,
as it inappropriately parses the concrete type parameter as a generic
argument. If the `ZeroablePrimitive` trait was stable, or the macro
could be modified to accept a finite list of types, then we could fully
migrate.
# 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
Spamming the window close button on window may trigger a panic.
```
thread 'main' panicked at <Bevy repo>\crates\bevy_ecs\src\system\commands\mod.rs:1320:13:

## Solution
Don't panic when trying to insert the `ClosingWindow` component into a
entity.
## Testing
Found and tested on windows. I haven't checked if this bug happens on
linux or macos.
For testing I ran this code:
```rust
use std::{thread, time::Duration};
use bevy::prelude::*;
fn lag() {
thread::sleep(Duration::from_millis(300));
}
fn main() -> AppExit {
App::new()
.add_plugins(DefaultPlugins)
.add_systems(Update, lag)
.run()
}
```
Then spammed the window close button. The panic no longer occurs.
# 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
- 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
# Objective
- With the recent winit update, touchpad specific events can also be
triggered on mobile

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

- [x] Linux (x11)
- [x] Linux (Wayland)
- [x] Android
- [x] iOS
- [x] WASM/WebGPU
- [x] WASM/WebGL2
## Outstanding issues / regressions
- [ ] iOS: build failed in CI
- blocking, but may just be flakiness
- [x] Cross-platform: when the window is maximised, changes in the scale
factor don't apply, to make them apply one has to make the window
smaller again. (Re-maximising keeps the updated scale factor)
- non-blocking, but good to fix
- [ ] Android: it's pretty easy to quickly open and close the app and
then the music keeps playing when suspended.
- non-blocking but worrying
- [ ] Web: the application will hang when switching tabs
- Not new, duplicate of https://github.com/bevyengine/bevy/issues/13486
- [ ] Cross-platform?: Screenshot failure, `ERROR present_frames:
wgpu_core::present: No work has been submitted for this frame before`
taking the first screenshot, but after pressing space
- non-blocking, but good to fix

# Objective
Fixes two issues related to #13208.
First, we ensure render resources for a window are always dropped first
to ensure that the `winit::Window` always drops on the main thread when
it is removed from `WinitWindows`. Previously, changes in #12978 caused
the window to drop in the render world, causing issues.
We accomplish this by delaying despawning the window by a frame by
inserting a marker component `ClosingWindow` that indicates the window
has been requested to close and is in the process of closing. The render
world now responds to the equivalent `WindowClosing` event rather than
`WindowCloseed` which now fires after the render resources are
guarunteed to be cleaned up.
Secondly, fixing the above caused (revealed?) that additional events
were being delivered to the the event loop handler after exit had
already been requested: in my testing `RedrawRequested` and
`LoopExiting`. This caused errors to be reported try to send an exit
event on the close channel. There are two options here:
- Guard the handler so no additional events are delivered once the app
is exiting. I ~considered this but worried it might be confusing or bug
prone if in the future someone wants to handle `LoopExiting` or some
other event to clean-up while exiting.~ We are now taking this approach.
- Only send an exit signal if we are not already exiting. ~It doesn't
appear to cause any problems to handle the extra events so this seems
safer.~
Fixing this also appears to have fixed#13231.
Fixes#10260.
## Testing
Tested on mac only.
---
## Changelog
### Added
- A `WindowClosing` event has been added that indicates the window will
be despawned on the next frame.
### Changed
- Windows now close a frame after their exit has been requested.
## Migration Guide
- Ensure custom exit logic does not rely on the app exiting the same
frame as a window is closed.
# Objective
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
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
- Closes#12930.
## Solution
- Add a corresponding optional field on `Window` and `ExtractedWindow`
---
## Changelog
### Added
- `wgpu`'s `desired_maximum_frame_latency` is exposed through window
creation. This can be used to override the default maximum number of
queued frames on the GPU (currently 2).
## Migration Guide
- The `desired_maximum_frame_latency` field must be added to instances
of `Window` and `ExtractedWindow` where all fields are explicitly
specified.
# Objective
- Fixes#12976
## Solution
This one is a doozy.
- Run `cargo +beta clippy --workspace --all-targets --all-features` and
fix all issues
- This includes:
- Moving inner attributes to be outer attributes, when the item in
question has both inner and outer attributes
- Use `ptr::from_ref` in more scenarios
- Extend the valid idents list used by `clippy:doc_markdown` with more
names
- Use `Clone::clone_from` when possible
- Remove redundant `ron` import
- Add backticks to **so many** identifiers and items
- I'm sorry whoever has to review this
---
## Changelog
- Added links to more identifiers in documentation.
# Objective
- As @james7132 said [on
Discord](https://discord.com/channels/691052431525675048/692572690833473578/1224626740773523536),
the `close_on_esc` system is forcing `bevy_window` to depend on
`bevy_input`.
- `close_on_esc` is not likely to be used in production, so it arguably
does not have a place in `bevy_window`.
## Solution
- As suggested by @afonsolage, move `close_on_esc` into
`bevy_dev_tools`.
- Add an example to the documentation too.
- Remove `bevy_window`'s dependency on `bevy_input`.
- Add `bevy_reflect`'s `smol_str` feature to `bevy_window` because it
was implicitly depended upon with `bevy_input` before it was removed.
- Remove any usage of `close_on_esc` from the examples.
- `bevy_dev_tools` is not enabled by default. I personally find it
frustrating to run examples with additional features, so I opted to
remove it entirely.
- This is up for discussion if you have an alternate solution.
---
## Changelog
- Moved `bevy_window::close_on_esc` to `bevy_dev_tools::close_on_esc`.
- Removed usage of `bevy_dev_tools::close_on_esc` from all examples.
## Migration Guide
`bevy_window::close_on_esc` has been moved to
`bevy_dev_tools::close_on_esc`. You will first need to enable
`bevy_dev_tools` as a feature in your `Cargo.toml`:
```toml
[dependencies]
bevy = { version = "0.14", features = ["bevy_dev_tools"] }
```
Finally, modify any imports to use `bevy_dev_tools` instead:
```rust
// Old:
// use bevy:🪟:close_on_esc;
// New:
use bevy::dev_tools::close_on_esc;
App::new()
.add_systems(Update, close_on_esc)
// ...
.run();
```
# 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
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
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
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
Fix#12304. Remove unnecessary type registrations thanks to #4154.
## Solution
Conservatively remove type registrations. Keeping the top level
components, resources, and events, but dropping everything else that is
a type of a member of those types.
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
This is an implementation within `bevy_window::window` that fixes
#12229.
# Objective
Fixes#12229, allow users to retrieve the window's size and physical
size as Vectors without having to manually construct them using
`height()` and `width()` or `physical_height()` and `physical_width()`
## Solution
As suggested in #12229, created two public functions within `window`:
`size() -> Vec` and `physical_size() -> UVec` that return the needed
Vectors ready-to-go.
### Discussion
My first FOSS PRQ ever, so bear with me a bit. I'm new to this.
- I replaced instances of ```Vec2::new(window.width(),
window.height());``` or `UVec2::new(window.physical_width(),
window.physical_height());` within bevy examples be replaced with their
`size()`/`physical_size()` counterparts?
- Discussion within #12229 still holds: should these also be added to
WindowResolution?
# 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
- Fixes #4188, make users could set application ID for bevy apps.
## Solution
- Add `name` field to `bevy:🪟:Window`. Specifying this field adds
different properties to the window: application ID on `Wayland`,
`WM_CLASS` on `X11`, or window class name on Windows. It has no effect
on other platforms.
---
## Changelog
### Added
- Add `name` to `bevy:🪟:Window`.
## Migration Guide
- Set the `bevy_window::Window`'s `name` field when needed:
```rust
App::new()
.add_plugins(DefaultPlugins.set(WindowPlugin {
primary_window: Some(Window {
title: "I am a window!".into(),
name: Some("SpaceGameCompany.SpaceShooter".into()),
..default()
}),
..default()
}))
.run();
```

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

## Changelog
* `bevy:🪟:WindowMoved`'s `entity` field has been renamed to
`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
My motivation are to resolve some of the issues I describe in this
[PR](https://github.com/bevyengine/bevy/issues/11415):
- not being able to easily mapping entities because the current
EntityMapper requires `&mut World` access
- not being able to create my own `EntityMapper` because some components
(`Parent` or `Children`) do not provide any public way of modifying the
inner entities
This PR makes the `MapEntities` trait accept a generic type that
implements `Mapper` to perform the mapping.
This means we don't need to use `EntityMapper` to perform our mapping,
we can use any type that implements `Mapper`. Basically this change is
very similar to what `serde` does. Instead of specifying directly how to
map entities for a given type, we have 2 distinct steps:
- the user implements `MapEntities` to define how the type will be
traversed and which `Entity`s will be mapped
- the `Mapper` defines how the mapping is actually done
This is similar to the distinction between `Serialize` (`MapEntities`)
and `Serializer` (`Mapper`).
This allows networking library to map entities without having to use the
existing `EntityMapper` (which requires `&mut World` access and the use
of `world_scope()`)
## Migration Guide
- The existing `EntityMapper` (notably used to replicate `Scenes` across
different `World`s) has been renamed to `SceneEntityMapper`
- The `MapEntities` trait now works with a generic `EntityMapper`
instead of the specific struct `EntityMapper`.
Calls to `fn map_entities(&mut self, entity_mapper: &mut EntityMapper)`
need to be updated to
`fn map_entities<M: EntityMapper>(&mut self, entity_mapper: &mut M)`
- The new trait `EntityMapper` has been added to the prelude

# 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
