# 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
- Keep Taffy version up to date
Taffy 0.6 doesn't include a huge amount relevant to Bevy. But it does:
- Add the `box_sizing` style
- Expose the computed `margin` in layout
- Traitifies the `Style` struct, which opens up the possibility of using
Bevy's `Style` struct directly (although Bevy currently does some style
resolution at conversion time which would no longer be cached if it was
used directly).
- Have a few bug fixes in the layout algorithms
## Solution
- Upgrade Taffy to `0.6.0`
## Testing
- I've run the `grid` example. All looks good.
- More testing is probably warranted. We have had regressions from Taffy
upgrades before
- Having said that, most of the algorithm changes this cycle were driven
by fixing WPT tests run through the new Servo integration. So they're
possibly less likely than usual to cause regressions.
## Breaking changes
The only "breaking" change is adding a field to `Style`. Probably
doesn't bear mentioning?

# Objective
- Contributes to #15460
## Solution
- Added two new features, `std` (default) and `alloc`, gating `std` and
`alloc` behind them respectively.
- Added missing `f32` functions to `std_ops` as required. These `f32`
methods have been added to the `clippy.toml` deny list to aid in
`no_std` development.
## Testing
- CI
- `cargo clippy -p bevy_math --no-default-features --features libm
--target "x86_64-unknown-none"`
- `cargo test -p bevy_math --no-default-features --features libm`
- `cargo test -p bevy_math --no-default-features --features "libm,
alloc"`
- `cargo test -p bevy_math --no-default-features --features "libm,
alloc, std"`
- `cargo test -p bevy_math --no-default-features --features "std"`
## Notes
The following items require the `alloc` feature to be enabled:
- `CubicBSpline`
- `CubicBezier`
- `CubicCardinalSpline`
- `CubicCurve`
- `CubicGenerator`
- `CubicHermite`
- `CubicNurbs`
- `CyclicCubicGenerator`
- `RationalCurve`
- `RationalGenerator`
- `BoxedPolygon`
- `BoxedPolyline2d`
- `BoxedPolyline3d`
- `SampleCurve`
- `SampleAutoCurve`
- `UnevenSampleCurve`
- `UnevenSampleAutoCurve`
- `EvenCore`
- `UnevenCore`
- `ChunkedUnevenCore`
This requirement could be relaxed in certain cases, but I had erred on
the side of gating rather than modifying. Since `no_std` is a new set of
platforms we are adding support to, and the `alloc` feature is enabled
by default, this is not a breaking change.

# Objective
~Blocked on #13417~
Motivation is the same as in #13417. If users can sort `QueryIter`, to
only makes sense to also allow them to use this functionality on
`QueryManyIter`.
## Solution
Also implement the sorts on `QueryManyIter`.
The implementation of the sorts themselves are mostly the same as with
`QueryIter` in #13417.
They differ in that they re-use the `entity_iter` passed to the
`iter_many`, and internally call `iter_many_unchecked_manual` on the
lens `QueryState` with it.
These methods also return a different struct, `QuerySortedManyIter`,
because there is no longer a guarantee of unique entities.
`QuerySortedManyIter` implements the various `Iterator` traits for
read-only iteration, as `QueryManyIter` does + `DoubleEndedIterator`.
For mutable iteration, there is both a `fetch_next` and a
`fetch_next_back` method. However, they only become available after the
user calls `collect_inner` on `QuerySortedManyIter` first. This collects
the inner `entity_iter` (this is the sorted one, **not** the original
the user passed) to drop all query lens items to avoid aliasing.
When TAITs are available this `collect_inner` could be hidden away,
until then it is unfortunately not possible to elide this without either
regressing read-only iteration, or introducing a whole new type, mostly
being a copy of `QuerySortedIter`.
As a follow-up we could add a `entities_all_unique` method to check
whether the entity list consists of only unique entities, and then
return a `QuerySortedIter` from it (under opaque impl Trait if need be),
*allowing mutable `Iterator` trait iteration* over what was originally
an `iter_many` call.
Such a method can also be added to `QueryManyIter`, albeit needing a
separate, new return type.
## Testing
I've switched the third example/doc test under `sort` out for one that
shows the collect_inner/fetch_next_back functionality, otherwise the
examples are the same as in #13417, adjusted to use `iter_many` instead
of `iter`.
The `query-iter-many-sorts` test checks for equivalence to the
underlying sorts.
The test after shows that these sorts *do not* panic after
`fetch`/`fetch_next` calls.
## Changelog
Added `sort`, `sort_unstable`, `sort_by`, `sort_unstable_by`,
`sort_by_key`, `sort_by_cached_key` to `QueryManyIter`.
Added `QuerySortedManyIter`.

# Objective
Add support for multiple box shadows on a single `Node`.
## Solution
* Rename `BoxShadow` to `ShadowStyle` and remove its `Component` derive.
* Create a new `BoxShadow` component that newtypes a `Vec<ShadowStyle>`.
* Add a `new` constructor method to `BoxShadow` for single shadows.
* Change `extract_shadows` to iterate through a list of shadows per
node.
Render order is determined implicitly from the order of the shadows
stored in the `BoxShadow` component, back-to-front.
Might be more efficient to use a `SmallVec<[ShadowStyle; 1]>` for the
list of shadows but not sure if the extra friction is worth it.
## Testing
Added a node with four differently coloured shadows to the `box_shadow`
example.

## Migration Guide
Bevy UI now supports multiple shadows per node. A new struct
`ShadowStyle` is used to set the style for each shadow. And the
`BoxShadow` component is changed to a tuple struct wrapping a vector
containing a list of `ShadowStyle`s. To spawn a node with a single
shadow you can use the `new` constructor function:
```rust
commands.spawn((
Node::default(),
BoxShadow::new(
Color::BLACK.with_alpha(0.8),
Val::Percent(offset.x),
Val::Percent(offset.y),
Val::Percent(spread),
Val::Px(blur),
)
));

# Objective
- Fixes: #15663
## Solution
- Add an `is_forward_plane` method to `Aabb`, and a `contains_aabb`
method to `Frustum`.
## Test
- I have created a frustum with an offset along with three unit tests to
evaluate the `contains_aabb` algorithm.
## Explanation for the Test Cases
- To facilitate the code review, I will explain how the frustum is
created. Initially, we create a frustum without any offset and then
create a cuboid that is just contained within it.
<img width="714" alt="image"
src="https://github.com/user-attachments/assets/a9ac53a2-f8a3-4e09-b20b-4ee71b27a099">

y-axis to make it more general.

# Objective
- I got tired of calling `enable_state_scoped_entities`, and though it
would make more sense to define that at the place where the state is
defined
## Solution
- add a derive attribute `#[states(scoped_entities)]` when derive
`States` or `SubStates` that enables it automatically when adding the
state
## Testing
- Ran the examples using it, they still work
# Objective
There is currently no way of getting `QueryState` from `&World`, so it
is hard to, for example, iterate over all entities with a component,
only having `&World`.
## Solution
Add `try_new` function to `QueryState` that internally uses
`WorldQuery`'s `get_state`.
## Testing
No testing
# Objective
Combine the `Option<_>` state in `FunctionSystem` into a single `Option`
to provide clarity and save space.
## Solution
Simplifies `FunctionSystem`'s layout by using a single
`Option<FunctionSystemState>` for state that must be initialized before
running, and saves a byte by removing the need to store an enum tag.
Additionally, calling `System::run` on an uninitialized `System` will
now give a more descriptive message prior to verifying the `WorldId`.
## Testing
Ran CI checks locally.
# Objective
See title.
## Solution
Move `bevy_animation` import to where it is used.
## Testing
Compiled with and without `bevy_animation` feature enabled.

Fixes#16531
I also added change detection when creating the pipeline, which
technically isn't needed but it felt weird leaving it as is.
## Solution
Remove the pipeline if CAS is disabled. The uniform was already being
removed, which caused flickering / weirdness.
## Testing
Tested the anti_alias example by toggling CAS a bunch on/off.
# Objective
Animating component fields requires too much boilerplate at the moment:
```rust
#[derive(Reflect)]
struct FontSizeProperty;
impl AnimatableProperty for FontSizeProperty {
type Component = TextFont;
type Property = f32;
fn get_mut(component: &mut Self::Component) -> Option<&mut Self::Property> {
Some(&mut component.font_size)
}
}
animation_clip.add_curve_to_target(
animation_target_id,
AnimatableKeyframeCurve::new(
[0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0]
.into_iter()
.zip([24.0, 80.0, 24.0, 80.0, 24.0, 80.0, 24.0]),
)
.map(AnimatableCurve::<FontSizeProperty, _>::from_curve)
.expect("should be able to build translation curve because we pass in valid samples"),
);
```
## Solution
This adds `AnimatedField` and an `animated_field!` macro, enabling the
following:
```rust
animation_clip.add_curve_to_target(
animation_target_id,
AnimatableCurve::new(
animated_field!(TextFont::font_size),
AnimatableKeyframeCurve::new(
[0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0]
.into_iter()
.zip([24.0, 80.0, 24.0, 80.0, 24.0, 80.0, 24.0]),
)
.expect(
"should be able to build translation curve because we pass in valid samples",
),
),
);
```
This required reworking the internals a bit, namely stripping out a lot
of the `Reflect` usage, as that implementation was fundamentally
incompatible with the `AnimatedField` pattern. `Reflect` was being used
in this context just to downcast traits. But we can get downcasting
behavior without the `Reflect` requirement by implementing `Downcast`
for `AnimationCurveEvaluator`.
This also reworks "evaluator identity" to support either a (Component /
Field) pair, or a TypeId. This allows properties to reuse evaluators,
even if they have different accessor methods. The "contract" here is
that for a given (Component / Field) pair, the accessor will return the
same value. Fields are identified by their Reflect-ed field index. The
(TypeId, usize) is prehashed and cached to optimize for lookup speed.
This removes the built-in hard-coded TranslationCurve / RotationCurve /
ScaleCurve in favor of AnimatableField.

# Objective
The documentation for `bevy_app::App.world()` (and its mut variant)
could confuse some into thinking that this is the only World that the
App will contain.
## Solution
Clarify the documentation for `bevy_app::App.world()` (and its mut
variant), to say that it returns the main subapp's world. This helps
imply that Apps can contain more than one world (albeit, only one per
SubApp).
## Testing
This is a documentation change, with no changes to doctests. Thus,
testing is not necessary beyond ensuring the link syntax is correct.
# Objective
Fixes#16521
## Solution
If an empty span is encountered (such as the default `Text` value), we
skip it entirely when updating buffers. This prevents unnecessarily
bailing when the font doesn't exist (ex: when the default font is
disabled)

the doc link for `Single` actually links to `Query::single`, and
`Option<Single>` just links to `Option`. They should both link to
`Single`!
The first link is broken because there is a reference-style link defined
for `single`, but not for `Single`, and rustdoc treats the link as
case-insensitive for some reason.
## Solution
Fix the links!
## Testing
I built the docs locally with `cargo doc` and tested the links.

## Migration Guide
`RenderCreation::Manual` variant fields are now wrapped in a struct
called `RenderResources`
# Objective
`TemporaryRenderEntity` currently uses `SparseSet` storage, but doesn't
seem to fit the criteria for a component that would benefit from this.
Typical usage of `TemporaryRenderEntity` (and all current usages of it
in engine as far as I can tell) would be to spawn an entity with it once
and then iterate over it once to despawn that entity.
`SparseSet` is said to be useful for insert/removal perf at the cost of
iteration perf.
## Solution
Use the default table storage
## Testing
Possibly this could show up in stress tests like `many_buttons`. I
didn't do any benchmarking.
# Objective
When using a rect for a ui image, its content size is still equal to the

texture atlas or not. See the showcase section.

# Objective
Original motivation was a bundle I am migrating that is `Copy` which
needs to be synced to the render world. It probably doesn't actually
*need* to be `Copy`, so this isn't critical or anything.
I am continuing to use this bundle while bundles still exist to give
users an easier migration path.
## Solution
These ZSTs might as well be `Copy`. Add `Copy` derives.
PR #15164 made Bevy consider the center of the mesh to be the center of
the axis-aligned bounding box (AABB). Unfortunately, this breaks
crossfading in many cases. LODs may have different AABBs and so the
center of the AABB may differ for different LODs of the same mesh. The
crossfading, however, relies on all LODs having *precisely* the same
position.
To address this problem, this PR adds a new field, `use_aabb`, to
`VisibilityRange`, which makes the AABB center point behavior opt-in.
@BenjaminBrienen first noticed this issue when reviewing PR #16286. That
PR contains a video showing the effects of this regression on the
`visibility_range` example. This commit fixes that example.
## Migration Guide
* The `VisibilityRange` component now has an extra field, `use_aabb`.
Generally, you can safely set it to false.
We have an early-out to avoid updating `RenderVisibilityRanges` when a
`VisibilityRange` component is *modified*, but not when one is
*removed*. This means that removing `VisibilityRange` from an entity
might not update the rendering.
This PR fixes the issue by adding a check for removed
`VisibilityRange`s.
# Objective
- Fixes#16472.
## Solution
- Add flags to `SpritePlugin` and `UiPlugin` to disable their picking
backends.
## Testing
- The change is pretty trivial, so not much to test!
---
## Migration Guide
- `UiPlugin` now contains an extra `add_picking` field if
`bevy_ui_picking_backend` is enabled.
- `SpritePlugin` is no longer a unit struct, and has one field if
`bevy_sprite_picking_backend` is enabled (otherwise no fields).
# Objective
- Fixes#16469.
## Solution
- Make the picking backend features not enabled by default in each
sub-crate.
- Make features in `bevy_internal` to set the backend features
- Make the root `bevy` crate set the features by default.
## Testing
- The mesh and sprite picking examples still work correctly.
I'm not sure why, but somehow `#[derive(Reflect)]` on a tuple struct

Adding `#[reflect(opaque)]` to the `Reflect` derive fixes the problem,
and that's what this patch does. I think that adding
`#[reflect(opaque)]` is harmless, as there's little that reflection
allows with a boxed trait object anyhow.

# Objective
We switch back and forwards between logical and physical coordinates all
over the place. Systems have to query for cameras and the UiScale when
they shouldn't need to. It's confusing and fragile and new scale factor
bugs get found constantly.
## Solution
* Use physical coordinates whereever possible in `bevy_ui`.
* Store physical coords in `ComputedNode` and tear out all the unneeded
scale factor calculations and queries.
* Add an `inverse_scale_factor` field to `ComputedNode` and set nodes
changed when their scale factor changes.
## Migration Guide
`ComputedNode`'s fields and methods now use physical coordinates.
`ComputedNode` has a new field `inverse_scale_factor`. Multiplying the
physical coordinates by the `inverse_scale_factor` will give the logical
values.

# Objective
Needing to derive `AnimationEvent` for `Event` is unnecessary, and the
trigger logic coupled to it feels like we're coupling "event producer"
logic with the event itself, which feels wrong. It also comes with a
bunch of complexity, which is again unnecessary. We can have the
flexibility of "custom animation event trigger logic" without this
coupling and complexity.
The current `animation_events` example is also needlessly complicated,
due to it needing to work around system ordering issues. The docs
describing it are also slightly wrong. We can make this all a non-issue
by solving the underlying ordering problem.
Related to this, we use the `bevy_animation::Animation` system set to
solve PostUpdate animation order-of-operations issues. If we move this
to bevy_app as part of our "core schedule", we can cut out needless
`bevy_animation` crate dependencies in these instances.
## Solution
- Remove `AnimationEvent`, the derive, and all other infrastructure
associated with it (such as the `bevy_animation/derive` crate)
- Replace all instances of `AnimationEvent` traits with `Event + Clone`
- Store and use functions for custom animation trigger logic (ex:
`clip.add_event_fn()`). For "normal" cases users dont need to think
about this and should use the simpler `clip.add_event()`
- Run the `Animation` system set _before_ updating text
- Move `bevy_animation::Animation` to `bevy_app::Animation`. Remove
unnecessary `bevy_animation` dependency from `bevy_ui`
- Adjust `animation_events` example to use the simpler `clip.add_event`
API, as the workarounds are no longer necessary
This is polishing work that will land in 0.15, and I think it is simple
enough and valuable enough to land in 0.15 with it, in the interest of
making the feature as compelling as possible.

= help: the following other types implement trait `fetch::QueryData`:
&'__w mut T
&Archetype
&T
()
(F,)

Alternative to #16450
# Objective
detailed_trace! in its current form does not work (and breaks CI)
## Solution
Fix detailed_trace by checking for the feature properly, adding it to
the correct crates, and removing it from the incorrect crates
# Objective
- Fixes#16406
- Fixes an issue where registering a "deeper" required component, then a
"shallower" required component, would result in the wrong required
constructor being used for the root component.
## Solution
- Make `register_required_components` add any "parent" of a component as
`required_by` to the new "child".
- Assign the depth of the `requiree` plus 1 as the depth of a new
runtime required component.
## Testing
- Added two new tests.
# Objective
- Add methods to facilitate `TextFont` component creation and insertion.
## Solution
- Added `from_font` and `from_font_size` which return a new `TextFont`
with said attributes provided as parameters.
- Added `with_font` and `with_font_size` which return an existing
`TextFont` modifying said attributes with the values provided as
parameters.
## Testing
- CI Checks.
- Tested methods locally by changing values and running the `text_debug`
example.
