# Objective
Currently the resource doesn't get dropped if thread panics. This is
presumably to prevent !SEND resource from being dropped by wrong thread.
But, this logic is not needed for SEND resources. So we don't need this
check for SEND resource.
Fixes#15144
## Solution
We check if resource is !SEND before, validating that correct thread is
dropping the resource.

# Objective
Currently, UI is always rendered with anti-aliasing. This makes bevy's
UI completely unsuitable for art-styles that demands hard pixelated
edges, such as retro-style games.
## Solution
Add a component for disabling anti-aliasing in UI.
## Testing
In
[`examples/ui/button.rs`](15e246eff8/examples/ui/button.rs),
add the component to the camera like this:
```rust
use bevy::{prelude::*, ui::prelude::*};
commands.spawn((Camera2dBundle::default(), UiAntiAlias::Off));
```
The rounded button will now render without anti-aliasing.
## Showcase
An example of a rounded UI node rendered without anti-aliasing, with and
without borders:
# Objective
- Another way of specifying rotations was requested in
https://github.com/bevyengine/bevy/issues/11132#issuecomment-2344603178
## Solution
- Add methods on `Rot2`
- `turn_fraction(fraction: f32) -> Self`
- `as_turn_fraction(self) -> f32`
- Also add some documentation on range of rotation
## Testing
- extended existing tests
- added new tests
## Showcase
```rust
let rotation1 = Rot2::degrees(90.0);
let rotation2 = Rot2::turn_fraction(0.25);
// rotations should be equal
assert_relative_eq!(rotation1, rotation2);
// The rotation should be 90 degrees
assert_relative_eq!(rotation2.as_radians(), FRAC_PI_2);
assert_relative_eq!(rotation2.as_degrees(), 90.0);

# Objective
- Adds the missing API commands `insert_if_new_and` and
`try_insert_if_new_and` (resolves#15105)
- Adds some test coverage for existing insert commands
## Testing
- Implemented additional unit tests to add coverage
# Objective
Right now, `DynSystemParam::downcast()` always requires the type
parameter to be specified with a turbofish. Make it so that it can be
inferred from the use of the return value, like:
```rust
fn expects_res_a(mut param: DynSystemParam) {
let res: Res<A> = param.downcast().unwrap();
}
```
## Solution
The reason this doesn't currently work is that the type parameter is a
`'static` version of the `SystemParam` so that it can be used with
`Any::downcast_mut()`. Change the method signature so that the type
parameter matches the return type, and use `T::Item<'static, 'static>`
to get the `'static` version. That means we wind up returning a
`T::Item<'static, 'static>::Item<'w, 's>`, so constrain that to be equal
to `T`. That works with every `SystemParam` implementation, since they
have `T::Item == T` up to lifetimes.
# Objective
Fixes#14540
## Solution
- Clean slab layouts from stale `SlabId`s when freeing meshes
- Technically performance requirements of freeing now increase based on
the number of existing meshes, but maybe it doesn't matter too much in
practice
- This was the case before this PR too, but it's technically possible to
free and allocate 2^32 times and overflow with `SlabId`s and cause
incorrect behavior. It looks like new meshes would then override old
ones.
## Testing
- Tested in `loading_screen` example and tapping keyboard 1 and 2.
# Objective
- fix#12853
- Make `Table::allocate` faster
## Solution
The PR consists of multiple steps:
1) For the component data: create a new data-structure that's similar to
`BlobVec` but doesn't store `len` & `capacity` inside of it: "BlobArray"
(name suggestions welcome)
2) For the `Tick` data: create a new data-structure that's similar to
`ThinSlicePtr` but supports dynamic reallocation: "ThinArrayPtr" (name
suggestions welcome)
3) Create a new data-structure that's very similar to `Column` that
doesn't store `len` & `capacity` inside of it: "ThinColumn"
4) Adjust the `Table` implementation to use `ThinColumn` instead of
`Column`
The result is that only one set of `len` & `capacity` is stored in
`Table`, in `Table::entities`
### Notes Regarding Performance
Apart from shaving off some excess memory in `Table`, the changes have
also brought noteworthy performance improvements:
The previous implementation relied on `Vec::reserve` &
`BlobVec::reserve`, but that redundantly repeated the same if statement
(`capacity` == `len`). Now that check could be made at the `Table` level
because the capacity and length of all the columns are synchronized;
saving N branches per allocation. The result is a respectable
performance improvement per every `Table::reserve` (and subsequently
`Table::allocate`) call.
I'm hesitant to give exact numbers because I don't have a lot of
experience in profiling and benchmarking, but these are the results I
got so far:
*`add_remove_big/table` benchmark after the implementation:*
*`add_remove_big/table` benchmark in main branch (measured in comparison
to the implementation):*
*`add_remove_very_big/table` benchmark after the implementation:*
*`add_remove_very_big/table` benchmark in main branch (measured in
comparison to the implementation):*

## Changelog
- New data-structure that's similar to `BlobVec` but doesn't store `len`
& `capacity` inside of it: `BlobArray`
- New data-structure that's similar to `ThinSlicePtr` but supports
dynamic allocation:`ThinArrayPtr`
- New data-structure that's very similar to `Column` that doesn't store
`len` & `capacity` inside of it: `ThinColumn`
- Adjust the `Table` implementation to use `ThinColumn` instead of
`Column`
- New benchmark: `add_remove_very_big` to benchmark the performance of
spawning a lot of entities with a lot of components (15) each
## Migration Guide
`Table` now uses `ThinColumn` instead of `Column`. That means that
methods that previously returned `Column`, will now return `ThinColumn`
instead.
`ThinColumn` has a much more limited and low-level API, but you can
still achieve the same things in `ThinColumn` as you did in `Column`.
For example, instead of calling `Column::get_added_tick`, you'd call
`ThinColumn::get_added_ticks_slice` and index it to get the specific
added tick.

# Objective
It would be convenient to be able to quickly deny or allow all
components and resources on a `DynamicSceneBuilder` with a single method
call.
Context: #15210 renamed `{allow/deny}_all` to
`{allow/deny}_all_components`.
## Solution
Added two new methods to `DynamicSceneBuilder`, `allow_all` and
`deny_all`, which affect both the component and resource filters.
## Showcase
### Before
```rust
let builder = DynamicSceneBuilder::from_world(world)
.deny_all_components()
.deny_all_resources();
```
### After
```rust
let builder = DynamicSceneBuilder::from_world(world).deny_all();
```
The function `bevy_input::schedule::condition::Condition::or_else` has
been deprecated in favor of
`bevy_input::schedule::condition::Condition::or`. However the docs for
`ButtonInput` were still using the deprecated function in their example.
# Objective
The method names on `DynamicSceneBuilder` are misleading. Specifically,
`deny_all` and `allow_all` implies everything will be denied/allowed,
including all components and resources. In reality, these methods only
apply to components (which is mentioned in the docs).
## Solution
- change `deny_all` and `allow_all` to `deny_all_components` and
`allow_all_components`
- also, change the remaining methods to mention component where it makes
sense
We could also add the `deny_all` and `allow_all` methods back later,
only this time, they would deny/allow both resources and components.
## Showcase
### Before
```rust
let builder = DynamicSceneBuilder::from_world(world)
.deny_all()
.deny_all_resources()
.allow::<MyComponent>();
```
### After
```rust
let builder = DynamicSceneBuilder::from_world(world)
.deny_all_components()
.deny_all_resources()
.allow_component::<MyComponent>();
```
## Migration Guide
the following invocations on `DynamicSceneBuilder` should be changed by
users
- `with_filter` -> `with_component_filter`
- `allow` -> `allow_component`
- `deny` -> `deny_component`
- `allow_all` -> `allow_all_components`
- `deny_all` -> `deny_all_components`
# Objective
Fix#10284.
## Solution
When `DynamicSceneBuilder` extracts entities, they are cloned via
`PartialReflect::clone_value`, making them into dynamic versions of the
original components. This loses any custom `ReflectSerialize` type data.
Dynamic scenes are deserialized with the original types, not the dynamic
versions, and so any component with a custom serialize may fail. In this
case `Rect` and `Vec2`. The dynamic version includes the field names 'x'
and 'y' but the `Serialize` impl doesn't, hence the "expect float"
error.
The solution here: Instead of using `clone_value` to clone the
components, `FromReflect` clones and retains the original information
needed to serialize with any custom `Serialize` impls. I think using
something like `reflect_clone` from
(https://github.com/bevyengine/bevy/pull/13432) might make this more
efficient.
I also did the same when deserializing dynamic scenes to appease some of
the round-trip tests which use `ReflectPartialEq`, which requires the
types be the same and not a unique/proxy pair. I'm not sure it's
otherwise necessary. Maybe this would also be more efficient when
spawning dynamic scenes with `reflect_clone` instead of `FromReflect`
again?
An alternative solution would be to fall back to the dynamic version
when deserializing `DynamicScene`s if the custom version fails. I think
that's possible. Or maybe simply always deserializing via the dynamic
route for dynamic scenes?
## Testing
This example is similar to the original test case in #10284:
``` rust
#![allow(missing_docs)]
use bevy::{prelude::*, scene::SceneInstanceReady};
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_systems(Startup, (save, load).chain())
.observe(check)
.run();
}
static SAVEGAME_SAVE_PATH: &str = "savegame.scn.ron";
fn save(world: &mut World) {
let entity = world.spawn(OrthographicProjection::default()).id();
let scene = DynamicSceneBuilder::from_world(world)
.extract_entity(entity)
.build();
if let Some(registry) = world.get_resource::<AppTypeRegistry>() {
let registry = registry.read();
let serialized_scene = scene.serialize(®istry).unwrap();
// println!("{}", serialized_scene);
std::fs::write(format!("assets/{SAVEGAME_SAVE_PATH}"), serialized_scene).unwrap();
}
world.entity_mut(entity).despawn_recursive();
}
fn load(mut commands: Commands, asset_server: Res<AssetServer>) {
commands.spawn(DynamicSceneBundle {
scene: asset_server.load(SAVEGAME_SAVE_PATH),
..default()
});
}
fn check(_trigger: Trigger<SceneInstanceReady>, query: Query<&OrthographicProjection>) {
dbg!(query.single());
}
```
## Migration Guide
The `DynamicScene` format is changed to use custom serialize impls so
old scene files will need updating:

# Objective
- Fixes#14552
- Make the current note of `before` and `after` understandable.
- > The given set is not implicitly added to the schedule when this
system set is added.
## Solution
- Replace note in docs of [`after` and
`before`](https://docs.rs/bevy/latest/bevy/ecs/prelude/trait.IntoSystemConfigs.html#method.before)
- Note of after was removed completely, and links to `before`, because
they notes would be identical.
- Also encourage to use `.chain`, which is much simpler and safer to use
## Testing
- Checked the docs after running `cargo doc` and `cargo run -p ci --
lints`
- Are there any parts that need more testing?
- no need to test, but please review the text. If it is still including
the intended message and especially if its understandable.

# Objective
`Capsule2d::sample_interior` uses the radius of the capsule for the
width of its rectangular section. It should be using two times the
radius for the full width!
I noticed this as I was getting incorrect results for angular inertia
approximated from a point cloud of points sampled on the capsule. This
hinted that something was wrong with the sampling.
## Solution
Multiply the radius by two to get the full width of the rectangular
section. With this, the sampling produces the correct result in my
tests.
# Objective
- implements ParsedPath::try_from<&str>
- resolves#14438
## Testing
- Added unit test for ParsedPath::try_from<&str>
Note: I don't claim to be an expert on lifetimes! That said I think it
makes sense that the error shares a lifetime with input string as deeper
down it is used to construct it.
# Objective
Thanks to #7207, we now have a way to validate at the type-level that a
reflected value is actually the type it says it is and not just a
dynamic representation of that type.
`dyn PartialReflect` values _might_ be a dynamic type, but `dyn Reflect`
values are guaranteed to _not_ be a dynamic type.
Therefore, we can start to add methods to `Reflect` that weren't really
possible before. For example, we should now be able to always get a
`&'static TypeInfo`, and not just an `Option<&'static TypeInfo>`.
## Solution
Add the `DynamicTyped` trait.
This trait is similar to `DynamicTypePath` in that it provides a way to
use the non-object-safe `Typed` trait in an object-safe way.
And since all types that derive `Reflect` will also derive `Typed`, we
can safely add `DynamicTyped` as a supertrait of `Reflect`. This allows
us to use it when just given a `dyn Reflect` trait object.
## Testing
You can test locally by running:
```
cargo test --package bevy_reflect
```
---
## Showcase
`Reflect` now has a supertrait of `DynamicTyped`, allowing `TypeInfo` to
be retrieved from a `dyn Reflect` trait object without having to unwrap
anything!
```rust
let value: Box<dyn Reflect> = Box::new(String::from("Hello!"));
// BEFORE
let info: &'static TypeInfo = value.get_represented_type_info().unwrap();
// AFTER
let info: &'static TypeInfo = value.reflect_type_info();
```
## Migration Guide
`Reflect` now has a supertrait of `DynamicTyped`. If you were manually
implementing `Reflect` and did not implement `Typed`, you will now need
to do so.
# Objective
Fixes#14980
## Solution
Only iterate over archetypes containing the component.
## Alternatives
Additionally, for each archetype, cache how many observers are watching
one of its components & use this to speed up the check for each affected
archetype ([implemented
here](55c89aa033)).
Benchmarking showed this to lead only to a minor speedup.
## Testing
There's both already a test checking that observers don't run after
being despawned as well as a regression test for the bug that
necessitates the check this PR optimizes.
# Objective
Fixes https://github.com/bevyengine/bevy/issues/13225
## Solution
Invalidate `TrackedRenderPass` internal state upon accessing internal
`wgpu::RenderPass`.
## Testing
- Tested by calling `set_bind_group` on `RenderPass` returned by
`TrackedRenderPass::wgpu_pass` and checking if in later `set_bind_group`
calls on `TrackedRenderPass` correct bind group is restored.
# Objective
- Finish resolving https://github.com/bevyengine/bevy/issues/15125
- Inserting bundles was implemented in
https://github.com/bevyengine/bevy/pull/15128 but removing bundles still
needed to be implemented.
## Solution
- Modified `bevy_ecs::reflect::entity_commands::remove_reflect` to
handle both components and bundles
- Modified documentation of `ReflectCommandExt` methods to reflect that
one can now use bundles with these commands.
## Testing
- Three tests were added to match the ones for inserting components.
# Objective
- Remove any ambiguity around how multiple `Observer` components work on
a single `Entity` by completely removing the concept.
- Fixes#15122
## Solution
- Removed type parameters from `Observer`, relying on a function pointer
to provide type information into the relevant aspects of running an
observer.
## Testing
- Ran CI locally.
- Checked `observers.rs` example continued to function as expected.
## Notes
This communicates to users of observers that only a single `Observer`
can be inserted onto an entity at a time within the established type
system. This has been achieved by erasing the type information from the
stored `ObserverSystem` and retrieving it again using a function
pointer. This has the downside of increasing the size of the `Observer`
component and increases the complexity of the observer runner. However,
this complexity was already present, and is in my opinion a worthwhile
tradeoff for the clearer user experience.
The other notable benefit is users no longer need to use the
`ObserverState` component to filter for `Observer` entities, and can
instead use `Observer` directly.
Technically this is a breaking change, since the type signature for
`Observer` has changed. However, it was so cumbersome to use that I
don't believe there are any instances in the wild of users directly
naming `Observer` types, instead relying on `ObserverState`, and the
methods provided by `App` and `World`. As can be seen in the diff, this
change had very little knock-on effects across Bevy.
## Migration Guide
If you filtered for observers using `Observer<A, B>`, instead filter for
an `Observer`.

# Objective
The module docs for `bevy_reflect::func` don't mention the
`FunctionRegistry`.
## Solution
Add a section about the `FunctionRegistry` to the module-level
documentation.
## Testing
You can test locally by running:
```
cargo test --doc --package bevy_reflect --all-features
```
# Objective
- Fixes https://github.com/bevyengine/bevy/pull/14991. The `cosmic-text`
shape run cache requires manual cleanup for old text that no longer
needs to be cached.
## Solution
- Add a system to trim the cache.
- Add an `average fps` indicator to the `text_debug` example.
## Testing
Tested with `cargo run --example text_debug`.
- **No shape run cache**: 82fps with ~1fps variance.
- **Shape run cache no trim**: 90-100fps with ~2-4fps variance
- **Shape run cache trim age = 1**: 90-100fps with ~2-8fps variance
- **Shape run cache trim age = 2**: 90-100fps with ~2-4fps variance
- **Shape run cache trim age = 2000**: 80-120fps with ~2-6fps variance
The shape run cache seems to increase average FPS but also increases
frame time variance (when there is dynamic text).
# Objective
The names of numerous rendering components in Bevy are inconsistent and
a bit confusing. Relevant names include:
- `AutoExposureSettings`
- `AutoExposureSettingsUniform`
- `BloomSettings`
- `BloomUniform` (no `Settings`)
- `BloomPrefilterSettings`
- `ChromaticAberration` (no `Settings`)
- `ContrastAdaptiveSharpeningSettings`
- `DepthOfFieldSettings`
- `DepthOfFieldUniform` (no `Settings`)
- `FogSettings`
- `SmaaSettings`, `Fxaa`, `TemporalAntiAliasSettings` (really
inconsistent??)
- `ScreenSpaceAmbientOcclusionSettings`
- `ScreenSpaceReflectionsSettings`
- `VolumetricFogSettings`
Firstly, there's a lot of inconsistency between `Foo`/`FooSettings` and
`FooUniform`/`FooSettingsUniform` and whether names are abbreviated or
not.
Secondly, the `Settings` post-fix seems unnecessary and a bit confusing
semantically, since it makes it seem like the component is mostly just
auxiliary configuration instead of the core *thing* that actually
enables the feature. This will be an even bigger problem once bundles
like `TemporalAntiAliasBundle` are deprecated in favor of required
components, as users will expect a component named `TemporalAntiAlias`
(or similar), not `TemporalAntiAliasSettings`.
## Solution
Drop the `Settings` post-fix from the component names, and change some
names to be more consistent.
- `AutoExposure`
- `AutoExposureUniform`
- `Bloom`
- `BloomUniform`
- `BloomPrefilter`
- `ChromaticAberration`
- `ContrastAdaptiveSharpening`
- `DepthOfField`
- `DepthOfFieldUniform`
- `DistanceFog`
- `Smaa`, `Fxaa`, `TemporalAntiAliasing` (note: we might want to change
to `Taa`, see "Discussion")
- `ScreenSpaceAmbientOcclusion`
- `ScreenSpaceReflections`
- `VolumetricFog`
I kept the old names as deprecated type aliases to make migration a bit
less painful for users. We should remove them after the next release.
(And let me know if I should just... not add them at all)
I also added some very basic docs for a few types where they were
missing, like on `Fxaa` and `DepthOfField`.
## Discussion
- `TemporalAntiAliasing` is still inconsistent with `Smaa` and `Fxaa`.

Discord](https://discord.com/channels/691052431525675048/743663924229963868/1280601167209955431)
seemed to be that renaming to `Taa` would probably be fine, but I think
it's a bit more controversial, and it would've required renaming a lot
of related types like `TemporalAntiAliasNode`,
`TemporalAntiAliasBundle`, and `TemporalAntiAliasPlugin`, so I think
it's better to leave to a follow-up.
- I think `Fog` should probably have a more specific name like
`DistanceFog` considering it seems to be distinct from `VolumetricFog`.
~~This should probably be done in a follow-up though, so I just removed
the `Settings` post-fix for now.~~ (done)

## Migration Guide
Many rendering components have been renamed for improved consistency and
clarity.
- `AutoExposureSettings` → `AutoExposure`
- `BloomSettings` → `Bloom`
- `BloomPrefilterSettings` → `BloomPrefilter`
- `ContrastAdaptiveSharpeningSettings` → `ContrastAdaptiveSharpening`
- `DepthOfFieldSettings` → `DepthOfField`
- `FogSettings` → `DistanceFog`
- `SmaaSettings` → `Smaa`
- `TemporalAntiAliasSettings` → `TemporalAntiAliasing`
- `ScreenSpaceAmbientOcclusionSettings` → `ScreenSpaceAmbientOcclusion`
- `ScreenSpaceReflectionsSettings` → `ScreenSpaceReflections`
- `VolumetricFogSettings` → `VolumetricFog`

# 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.");
},
_ => {},
}
}
}
```

Hello! I am adopting #11022 to resolve conflicts with `main`. tldr: this
removes `scale` in favour of `scaling_mode`. Please see the original PR
for explanation/discussion.
Also relates to #2580.
## Migration Guide
Replace all uses of `scale` with `scaling_mode`, keeping in mind that
`scale` is (was) a multiplier. For example, replace
```rust
scale: 2.0,
scaling_mode: ScalingMode::FixedHorizontal(4.0),
```
with
```rust
scaling_mode: ScalingMode::FixedHorizontal(8.0),
```

# Objective
Reflection serialization can be difficult to debug. A lot of times a
type fails to be serialized and the user is left wondering where that
type came from.
This is most often encountered with Bevy's scenes. Attempting to
serialize all resources in the world will fail because some resources
can't be serialized.
For example, users will often get complaints about `bevy_utils::Instant`
not registering `ReflectSerialize`. Well, `Instant` can't be serialized,
so the only other option is to exclude the resource that contains it.
But what resource contains it? This is where reflection serialization
can get a little tricky (it's `Time<Real>` btw).
## Solution
Add the `debug_stack` feature to `bevy_reflect`. When enabled, the
reflection serializers and deserializers will keep track of the current
type stack. And this stack will be used in error messages to help with
debugging.
Now, if we unknowingly try to serialize `Time<Real>`, we'll get the
following error:
```
type `bevy_utils::Instant` did not register the `ReflectSerialize` type data. For certain types, this may need to be registered manually using `register_type_data` (stack: `bevy_time::time::Time<bevy_time::real::Real>` -> `bevy_time::real::Real` -> `bevy_utils::Instant`)
```
### Implementation
This makes use of `thread_local!` to manage an internal `TypeInfoStack`
which holds a stack of `&'static TypeInfo`. We push to the stack before
a type is (de)serialized and pop from the stack afterwards.
Using a thread-local should be fine since we know two (de)serializers
can't be running at the same time (and if they're running on separate
threads, then we're still good).
The only potential issue would be if a user went through one of the
sub-serializers, like `StructSerializer`. However, I don't think many
users are going through these types (I don't even know if we necessarily
want to keep those public either, but we'll save that for a different
PR). Additionally, this is just a debug feature that only affects error
messages, so it wouldn't have any drastically negative effect. It would
just result in the stack not being cleared properly if there were any
errors.
Lastly, this is not the most performant implementation since we now
fetch the `TypeInfo` an extra time. But I figured that for a debug tool,
it wouldn't matter too much.
### Feature
This also adds a `debug` feature, which enables the `debug_stack`
feature.
I added it because I think we may want to potentially add more debug
tools in the future, and this gives us a good framework for adding
those. Users who want all debug features, present and future, can just
set `debug`. If they only want this feature, then they can just use
`debug_stack`.
I also made the `debug` feature default to help capture the widest
audience (i.e. the users who want this feature but don't know they do).
However, if we think it's better as a non-default feature, I can change
it!
And if there's any bikeshedding around the name `debug_stack`, let me
know!
## Testing
Run the following command:
```
cargo test --package bevy_reflect --features debug_stack
```
---
## Changelog
- Added the `debug` and `debug_stack` features to `bevy_reflect`
- Updated the error messages returned by the reflection serializers and
deserializers to include more contextual information when the
`debug_stack` or `debug` feature is enabled

`NoFrustumCulling` prevents meshes from being considered out of view
based on AABBs (sometimes useful for skinned meshes which don't
recalculate AABBs currently). it currently only applies for primary view
rendering, not for shadow rendering which can result in missing shadows.
## Solution
Add checks for `NoFrustumCulling` to `check_dir_light_mesh_visibility`
and `check_point_light_mesh_visibility` so that `NoFrustumCulling`
entities are rendered to all shadow views as well as all primary views.

I noticed some issues in `screenshot` example:
1. Cursor icon won't return from `SystemCursorIcon::Progress` to default
icon, even though screen shot saving is done.
2. Panics when exiting window: ``called `Result::unwrap()` on an `Err`
value:
NoEntities("bevy_ecs::query::state::QueryState<bevy_ecs::entity::Entity,
bevy_ecs::query::filter::With<bevy_window:🪟:Window>>")``
## Solution
1. Caused by cursor updating system not responding to [`CursorIcon`
component
removal](5cfcbf47ed/examples/window/screenshot.rs (L38)).
I believe it should, so change it to react to
`RemovedComponents<CursorIcon>`. (a suggestion)
2. Use `get_single` for window.

# Objective
- Improve robustness of state transitions. Currently events that should
be scoped to a specific state can leak between state scopes since events
live for two ticks.
- See https://github.com/bevyengine/bevy/issues/15072
## Solution
- Allow registering state scoped events that will be automatically
cleared when exiting a state. This is *most of the time* not obviously
useful, but enables users to write correct code that will avoid/reduce
edge conditions (such as systems that aren't state scoped polling for a
state scoped event and having unintended side effects outside a specific
state instance).
## Testing
Did not test.
---
## Showcase
Added state scoped events that will be automatically cleared when
exiting a state. Useful when you want to guarantee clean state
transitions.
Normal way to add an event:
```rust
fn setup(app: &mut App) {
app.add_event::<MyGameEvent>();
}
```
Add a state-scoped event (**NEW**):
```rust
fn setup(app: &mut App) {
app.add_state_scoped_event::<MyGameEvent>(GameState::Play);
}
```

# Objective
Some of the new compile error messages are a little unclear (at least to
me). For example:
```
error[E0277]: `tests::foo::Bar` can not be created through reflection
--> crates/bevy_reflect/src/lib.rs:679:18
|
679 | #[derive(Reflect)]
| ^^^^^^^ the trait `from_reflect::FromReflect` is not implemented for `tests::foo::Bar`
|
= note: consider annotating `tests::foo::Bar` with `#[derive(Reflect)]` or `#[derive(FromReflect)]`
```
While the annotation makes it clear that `FromReflect` is missing, it's
not very clear from the main error message.
My IDE lists errors with only their message immediately present:
<p align="center">
<img width="700" alt="Image of said IDE listing errors with only their
message immediately present. These errors are as follows:
\"`tests::foo::Bar` can not be created through reflection\", \"The trait
bound `tests::foo::Bar: RegisterForReflection` is not satisfied\", and
\"The trait bound `tests::foo::Bar: type_info::MaybeTyped` is not
satisfied\""
src="https://github.com/user-attachments/assets/42c24051-9e8e-4555-8477-51a9407446aa">
</p>
This makes it hard to tell at a glance why my code isn't compiling.
## Solution
Updated all `on_unimplemented` attributes in `bevy_reflect` to mention
the relevant trait—either the actual trait or the one users actually
need to implement—as well as a small snippet of what not implementing
them means.
For example, failing to implement `TypePath` now mentions missing a
`TypePath` implementation. And failing to implement `DynamicTypePath`
now also mentions missing a `TypePath` implementation, since that's the
actual trait users need to implement (i.e. they shouldn't implement
`DynamicTypePath` directly).
Lastly, I also added some missing `on_unimplemented` attributes for
`MaybeTyped` and `RegisterForReflection` (which you can see in the image
above).
Here's how this looks in my IDE now:
<p align="center">
<img width="700" alt="Similar image as before showing the errors listed
by the IDE. This time the errors read as follows: \"`tests::foo::Bar`
does not implement `FromReflect` so cannot be reified through
reflection\", \"`tests::foo::Bar` does not implement
`GetTypeRegistration` so cannot be registered for reflection\", and
\"`tests::foo::Bar` does not implement `Typed` so cannot provide static
type information\""
src="https://github.com/user-attachments/assets/f6f8501f-0450-4f78-b84f-00e7a18d0533">

## Testing
You can test by adding the following code and verifying the compile
errors are correct:
```rust

struct Bar;

Make choosing of diffuse indirect lighting explicit, instead of using
numerical conditions like `all(indirect_light == vec3(0.0f))`, as using
that may lead to unwanted light leakage.
## Solution
Use an explicit `found_diffuse_indirect` condition to indicate the found
indirect lighting source.
## Testing
I have tested examples `lightmaps`, `irradiance_volumes` and
`reflection_probes`, there are no visual changes. For further testing,
consider a "cave" scene with lightmaps and irradiance volumes. In the
cave there are some purly dark occluded area, those dark area will
sample the irradiance volume, and that is easy to leak light.
Hello,
I'd like to contribute to this project by adding some useful constants
and improving the documentation for the AspectRatio struct. Here's a
summary of the changes I've made:
1. Added new constants for common aspect ratios:
- SIXTEEN_NINE (16:9)
- FOUR_THREE (4:3)
- ULTRAWIDE (21:9)
2. Enhanced the overall documentation:
- Improved module-level documentation with an overview and use cases
- Expanded explanation of the AspectRatio struct with examples
- Added detailed descriptions and examples for all methods (both
existing and new)
- Included explanations for the newly introduced constant values
- Added clarifications for From trait implementations
These changes aim to make the AspectRatio API more user-friendly and
easier to understand. The new constants provide convenient access to
commonly used aspect ratios, which I believe will be helpful in many
scenarios.

# Objective
- Fixes#15060
## Solution
- Added `IdentityAssetTransformer<A>` which is an `AssetTransformer`
which infallibly returns the input `Asset` unmodified.
- Replaced `LoadAndSave` and `LoadAndSaveSettings` with type definitions
linking back to `LoadTransformAndSave` and
`LoadTransformAndSaveSettings` respectively.
- Marked `LoadAndSave` and `LoadAndSaveSettings` as depreciated with a
migration guide included, hinting to the user to use the underlying type
instead.
## Testing
- Ran CI locally
---
## Migration Guide
- Replace `LoadAndSave<L, S>` with `LoadTransformAndSave<L,
IdentityAssetTransformer<<L as AssetLoader>::Asset>, S>`
- Replace `LoadAndSaveSettings<L, S>` with
`LoadTransformAndSaveSettings<L, (), S>`
# Objective
- Improve the ergonomics of managing states.
## Solution
- Add `set_state` extension method to `Commands` so you don't need to
type out `ResMut<NextState<S>>` to update a state. It also reduces
system parameter list size when you already have `Commands`.
- I only updated a couple examples to showcase how it can be used. There
*is* a potential perf cost to introducing `Commands` so this method
shouldn't necessarily be used everywhere.
## Testing
- Tested the updated examples: `game_menu` and `alien_cake_addict`.
---
## Showcase
Add `Commands::set_state` method for easily updating states.
Set directly:
```rust
fn go_to_game(mut game_state: ResMut<NextState<GameState>>) {
game_state.set(GameState::Play);
}
```
Set with commands (**NEW**):
```rust
fn go_to_game(mut commands: Commands) {
commands.set_state(GameState::Play);
}
```

Original description:
# Objective
The default value for `near` in `OrthographicProjection` should be
different for 2d & 3d.
For 2d using `near = -1000` allows bevy users to build up scenes using
background `z = 0`, and foreground elements `z > 0` similar to css.
However in 3d `near = -1000` results in objects behind the camera being
rendered. Using `near = 0` works for 3d, but forces 2d users to assign
`z <= 0` for rendered elements, putting the background at some arbitrary
negative value.
There is no common value for `near` that doesn't result in a footgun or
usability issue for either 2d or 3d, so they should have separate
values.
There was discussion about other options in the discord
[0](https://discord.com/channels/691052431525675048/1154114310042292325),
but splitting `default()` into `default_2d()` and `default_3d()` seemed
like the lowest cost approach.

Sorts the iterator with itertools' sorted_by function. This is required
given that 'self.entries' is an immutable &[Box<dyn PartialReflect]

ensure that the items were in alphabetical order.
I haven't checked for performance implications.
Adds some methods to assist in building `ShaderStorageBuffer` without
using `bytemuck`. We keep the `&[u8]` constructors since this is still
modeled as a thin wrapper around the buffer descriptor, but should make
it easier to interact with at the cost of an extra allocation in the
`ShaderType` path for the buffer writer.

# Objective
It's possible to create UB using an implementation of `QueryFilter` that
performs mutable access, but that does not violate any documented safety
invariants.
This code:
```rust
#[derive(Component)]
struct Foo(usize);
// This derive is a simple way to get a valid WorldQuery impl. The QueryData impl isn't used.
#[derive(QueryData)]
#[query_data(mutable)]
struct BadFilter<'w> {
foo: &'w mut Foo,
}
impl QueryFilter for BadFilter<'_> {
const IS_ARCHETYPAL: bool = false;
unsafe fn filter_fetch(
fetch: &mut Self::Fetch<'_>,
entity: Entity,
table_row: TableRow,
) -> bool {
// SAFETY: fetch and filter_fetch have the same safety requirements
let f: &mut usize = &mut unsafe { Self::fetch(fetch, entity, table_row) }.foo.0;
println!("Got &mut at {f:p}");
true
}
}
let mut world = World::new();
world.spawn(Foo(0));
world.run_system_once(|query: Query<&Foo, BadFilter>| {
let f: &usize = &query.iter().next().unwrap().0;
println!("Got & at {f:p}");
query.iter().next().unwrap();
println!("Still have & at {f:p}");
});
```
prints:
```
Got &mut at 0x1924b92dfb0
Got & at 0x1924b92dfb0
Got &mut at 0x1924b92dfb0
Still have & at 0x1924b92dfb0
```
Which means it had an `&` and `&mut` alive at the same time.
The only `unsafe` there is around `Self::fetch`, but I believe that call
correctly upholds the safety invariant, and matches what `Added` and
`Changed` do.
## Solution
Make `QueryFilter` an unsafe trait and document the requirement that the
`WorldQuery` implementation be read-only.
## Migration Guide
`QueryFilter` is now an `unsafe trait`. If you were manually
implementing it, you will need to verify that the `WorldQuery`
implementation is read-only and then add the `unsafe` keyword to the
`impl`.
Since `StandardMaterial::emissive_exposure_weight` does not get packed
into the gbuffer in the deferred case, unpacking uses an implicit
default value for emissive's alpha channel.
This resulted in divergent behavior between the forward and deferred
renderers when using standard materials with default
emissive_exposure_weight, this value defaulting to `0.0` in the forward
case and `1.0` in the other.
This patch changes the implicit value in the deferred case to `0.0` in
order to match the behavior of the forward renderer. However, this still
does not solve the case where `emissive_exposure_weight` is not `0.0`.
# Objective
The `ser` and `de` modules in `bevy_reflect/serde` are very long and
difficult to navigate.
## Solution
Refactor both modules into many smaller modules that each have a single
primary focus (i.e. a `structs` module that only handles struct
serialization/deserialization).
I chose to keep the `ser` and `de` modules separate. We could have
instead broken it up kind (e.g. lists, maps, etc.), but I think this is
a little cleaner. Serialization and deserialization, while related, can
be very different. So keeping them separated makes sense for
organizational purposes.
That being said, if people disagree and think we should structure this a
different way, I am open to changing it.
Note that this PR's changes are mainly structural. There are a few
places I refactored code to reduce duplication and to make things a bit
cleaner, but these are largely cosmetic and shouldn't have any impact on
behavior.
### Other Details
This PR also hides a lot of the internal logic from being exported.
These were originally public, but it's unlikely they really saw any use
outside of these modules. In fact, you don't really gain anything by
using them outside of this module either.
By privatizing these fields and items, we also set ourselves up for more
easily changing internal logic around without involving a breaking
change.
I also chose not to mess around with tests since that would really blow
up the diff haha.
## Testing
You can test locally by running:
```
cargo test --package bevy_reflect --all-features
```
---
## Migration Guide
The fields on `ReflectSerializer` and `TypedReflectSerializer` are now
private. To instantiate, the corresponding constructor must be used:
```rust
// BEFORE
let serializer = ReflectSerializer {
value: &my_value,
registry: &type_registry,
};
// AFTER
let serializer = ReflectSerializer::new(&my_value, &type_registry);
```
Additionally, the following types are no longer public:
- `ArraySerializer`
- `EnumSerializer`
- `ListSerializer`
- `MapSerializer`
- `ReflectValueSerializer` (fully removed)
- `StructSerializer`
- `TupleSerializer`
- `TupleStructSerializer`
As well as the following traits:
- `DeserializeValue` (fully removed)
### Builder changes
- Increased meshlet max vertices/triangles from 64v/64t to 255v/128t
(meshoptimizer won't allow 256v sadly). This gives us a much greater
percentage of meshlets with max triangle count (128). Still not perfect,
we still end up with some tiny <=10 triangle meshlets that never really
get simplified, but it's progress.
- Removed the error target limit. Now we allow meshoptimizer to simplify
as much as possible. No reason to cap this out, as the cluster culling
code will choose a good LOD level anyways. Again leads to higher quality
LOD trees.
- After some discussion and consulting the Nanite slides again, changed
meshlet group error from _adding_ the max child's error to the group
error, to doing `group_error = max(group_error, max_child_error)`. Error
is already cumulative between LODs as the edges we're collapsing during
simplification get longer each time.
- Bumped the 65% simplification threshold to allow up to 95% of the
original geometry (e.g. accept simplification as valid even if we only
simplified 5% of the triangles). This gives us closer to
log2(initial_meshlet_count) LOD levels, and fewer meshlet roots in the
DAG.
Still more work to be done in the future here. Maybe trying METIS for
meshlet building instead of meshoptimizer.
Using ~8 clusters per group instead of ~4 might also make a big
difference. The Nanite slides say that they have 8-32 meshlets per
group, suggesting some kind of heuristic. Unfortunately meshopt's
compute_cluster_bounds won't work with large groups atm
(https://github.com/zeux/meshoptimizer/discussions/750#discussioncomment-10562641)
so hard to test.
Based on discussion from
https://github.com/bevyengine/bevy/discussions/14998,
https://github.com/zeux/meshoptimizer/discussions/750, and discord.
### Runtime changes
- cluster:triangle packed IDs are now stored 25:7 instead of 26:6 bits,
as max triangles per cluster are now 128 instead of 64
- Hardware raster now spawns 128 * 3 vertices instead of 64 * 3 vertices
to account for the new max triangles limit
- Hardware raster now outputs NaN triangles (0 / 0) instead of
zero-positioned triangles for extra vertex invocations over the cluster
triangle count. Shouldn't really be a difference idt, but I did it
anyways.
- Software raster now does 128 threads per workgroup instead of 64
threads. Each thread now loads, projects, and caches a vertex (vertices
0-127), and then if needed does so again (vertices 128-254). Each thread
then rasterizes one of 128 triangles.
- Fixed a bug with `needs_dispatch_remap`. I had the condition backwards
in my last PR, I probably committed it by accident after testing the
non-default code path on my GPU.

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
- `CursorIcon` had derived `Reflect`, but it wasn't registered
## Solution
- Use `register_type` on it
- I also moved the cursor code to it's own plugin because there was
starting to be too much cursor code outside the cursor file.
## Testing
- window_settings example still works with the custom cursor
# Objective
#14957 added the `pick_rounded_rect` function to `bevy_ui` in the
`picking_backend` module, which is gated behind the `bevy_picking`
feature. This function is used in that module, as well as in the `focus`
module. The latter usage is not gated behind the `bevy_picking` feature,
causing a compile error when the feature is disabled.
## Solution
Move the `pick_rounded_rect` function out of the `picking_backend`
module, as it does not depend on anything defined in that module. I put
it in `lib.rs` but it could reasonably be moved somewhere else instead.
## Testing
Encountered this compile error in a project and confirmed that this
patch fixes it.
# Objective
Fixes#13479
This also fixes the gaps you can sometimes observe in outlines
(screenshot from main, not this PR):

The outline around the last item in each section has vertical gaps.
## Solution
Draw the outlines with corner radius using the existing border rendering
for uinodes. The outline radius is very simple to calculate. We just
take the computed border radius of the node, and if it's greater than
zero, add it to the distance from the edge of the node to the outer edge
of the node's outline.

# 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#15032
## Solution
Reimplement support for the `flip_x` and `flip_y` fields.
This doesn't flip the border geometry, I'm not really sure whether that
is desirable or not.
Also fixes a bug that was causing the side and center slices to tile
incorrectly.
### Testing
```
cargo run --example ui_texture_slice_flip_and_tile
```

src="https://github.com/user-attachments/assets/bc044bae-1748-42ba-92b5-0500c87264f6">
With tiling need to use nearest filtering to avoid bleeding between the
slices.

# Objective
- follow of #14049 ,we could use it on our Parallel Iterator,this pr
also unified the used function in both regular iter and parallel
iterations.
## Performance
no performance regression for regular itertaion
3.5X faster in hybrid parallel iteraion,this number is far greater than
the benefits obtained in regular iteration(~1.81) because mutable
iterations on continuous memory can effectively reduce the cost of
mataining core cache coherence
# Objective
As discussed in https://github.com/bevyengine/bevy/issues/7386, system
order ambiguities within `DefaultPlugins` are a source of bugs in the
engine and badly pollute diagnostic output for users.
We should eliminate them!
This PR is an alternative to #15027: with all external ambiguities
silenced, this should be much less prone to merge conflicts and the test
output should be much easier for authors to understand.
Note that system order ambiguities are still permitted in the
`RenderApp`: these need a bit of thought in terms of how to test them,
and will be fairly involved to fix. While these aren't *good*, they'll
generally only cause graphical bugs, not logic ones.
## Solution
All remaining system order ambiguities have been resolved.
Review this PR commit-by-commit to see how each of these problems were
fixed.
## Testing
`cargo run --example ambiguity_detection` passes with no panics or
logging!
