# Objective
Remove Bevy internals from backtraces
## Solution
Executors insert `__rust_begin_short_backtrace` into the callstack
before running a system.

Full backtraces (`RUST_BACKTRACE=full`) are unchanged.
## Alternative solutions
Write a custom panic hook. This could potentially let use exclude a few
more callstack frames but requires a dependency on `backtrace` and is
incompatible with user-provided panic hooks.

## Changelog
- Backtraces now exclude many Bevy internals (unless
`RUST_BACKTRACE=full` is used)

# Objective
fix occasional crash from commands.insert when quickly spawning and
despawning skinned/morphed meshes
## Solution
use `try_insert` instead of `insert`. if the entity is deleted we don't
mind failing to add the `NoAutomaticBatching` marker.
# Objective
- Fixes https://github.com/bevyengine/bevy/issues/12380
## Solution
- Before #11986 AssetEvents were scheduled after PostUpdate. That pr
moved these into First. This PR moves them into Last which is closer to
how they were scheduled before.
# Objective
- After #12370, ci testing with minimal plugins doesn't hang but it
crash as the resource `ScreenshotManager` doesn't exist
## Solution
- Check if the resource exists
# 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
Provide guidelines for contributing code to `bevy_audio`, with a focus
on the critical sections of the audio engine.
## Changelog
Added to the crate-level documentation comment with a section
introducing audio programming, real-time safety and why it is important
to audio programming, as well as recommendations for some programming
use-cases. The section concludes with links to more resources about
audio programming.
I might have gone overboard with the writeup, but I didn't want to
assume a lot out of potential `bevy_audio` contributors, and so I spent
a bit of time defining terms as simply as I could.
I didn't want to pressure people to do so, but the first link on the
additional resources should really be "required reading" as it goes more
in depth about the why and how of audio programming.

# Objective
`ButtonInput<KeyCode>` documentation is currently incorrect/incomplete,
see #12273.
## Solution
Fix the documentation.
I think in the future we should also stop triggering
`just_pressed`/`just_released` when focus switches between two Bevy
windows, as those functions are independent of the window. It could also
make sense to add individual `ButtonInput<KeyCode>`s per window.

# Objective
- Fix#12356

This is an implementation of RFC #51:
https://github.com/bevyengine/rfcs/blob/main/rfcs/51-animation-composition.md
Note that the implementation strategy is different from the one outlined
in that RFC, because two-phase animation has now landed.
# Objective
Bevy needs animation blending. The RFC for this is [RFC 51].
## Solution
This is an implementation of the RFC. Note that the implementation
strategy is different from the one outlined there, because two-phase
animation has now landed.
This is just a draft to get the conversation started. Currently we're
missing a few things:
- [x] A fully-fleshed-out mechanism for transitions
- [x] A serialization format for `AnimationGraph`s
- [x] Examples are broken, other than `animated_fox`
- [x] Documentation
---
## Changelog
### Added
* The `AnimationPlayer` has been reworked to support blending multiple
animations together through an `AnimationGraph`, and as such will no
longer function unless a `Handle<AnimationGraph>` has been added to the
entity containing the player. See [RFC 51] for more details.
* Transition functionality has moved from the `AnimationPlayer` to a new
component, `AnimationTransitions`, which works in tandem with the
`AnimationGraph`.
## Migration Guide
* `AnimationPlayer`s can no longer play animations by themselves and
need to be paired with a `Handle<AnimationGraph>`. Code that was using
`AnimationPlayer` to play animations will need to create an
`AnimationGraph` asset first, add a node for the clip (or clips) you
want to play, and then supply the index of that node to the
`AnimationPlayer`'s `play` method.
* The `AnimationPlayer::play_with_transition()` method has been removed
and replaced with the `AnimationTransitions` component. If you were
previously using `AnimationPlayer::play_with_transition()`, add all
animations that you were playing to the `AnimationGraph`, and create an
`AnimationTransitions` component to manage the blending between them.

# Objective
- With the recent lighting changes, the default configuration in the
`bloom_3d` example is less clear what bloom actually does
- See [this
screenshot](4fdb1455d5 (r1494648414))
for a comparison.
- `bloom_3d` additionally uses a for-loop to spawn the spheres, which
can be turned into `commands::spawn_batch` call.
- The text is black, which is difficult to see on the gray background.
## Solution
- Increase emmisive values of materials.
- Set text to white.

# Objective
Make bevy_utils less of a compilation bottleneck. Tackle #11478.
## Solution
* Move all of the directly reexported dependencies and move them to
where they're actually used.
* Remove the UUID utilities that have gone unused since `TypePath` took
over for `TypeUuid`.
* There was also a extraneous bytemuck dependency on `bevy_core` that
has not been used for a long time (since `encase` became the primary way
to prepare GPU buffers).
* Remove the `all_tuples` macro reexport from bevy_ecs since it's
accessible from `bevy_utils`.
---
## Changelog
Removed: Many of the reexports from bevy_utils (petgraph, uuid, nonmax,
smallvec, and thiserror).
Removed: bevy_core's reexports of bytemuck.
## Migration Guide
bevy_utils' reexports of petgraph, uuid, nonmax, smallvec, and thiserror
have been removed.
bevy_core' reexports of bytemuck's types has been removed.
Add them as dependencies in your own crate instead.
# Objective
Fixes#12353
When only `webp` was selected, `ImageLoader` would not be initialized.
That is, users using `default-features = false` would need to add `png`
or `bmp` or something in addition to `webp` in order to use `webp`.
This was also the case for `pnm`.
## Solution
Add `webp` and `pnm` to the list of features that trigger the
initialization of `ImageLoader`.
# Objective
- Resolves#11309
## Solution
- Add `bevy_dev_tools` crate as a default feature.
- Add `DevToolsPlugin` and add it to an app if the `bevy_dev_tools`
feature is enabled.
`bevy_dev_tools` is reserved by @alice-i-cecile, should we wait until it
gets transferred to cart before merging?

# Objective
- Fix slightly wrong logic from #11442
- Directional lights should not have a near clip plane
## Solution
- Push near clip out to infinity, so that the frustum normal is still
available if its needed for whatever reason in shader
- also opportunistically nabs a typo
# 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.
# Objective
Following #10756, we're now using raw pointers in BundleInserter and
BundleSpawner. This is primarily to get around the need to split the
borrow on the World, but it leaves a lot to be desired in terms of
safety guarantees. There's no type level guarantee the code can't
dereference a null pointer, and it's restoring them to borrows fairly
liberally within the associated functions.
## Solution
* Replace the pointers with `NonNull` and a new `bevy_ptr::ConstNonNull`
that only allows conversion back to read-only borrows
* Remove the closure to avoid potentially aliasing through the closure
by restructuring the match expression.
* Move all conversions back into borrows as far up as possible to ensure
that the borrow checker is at least locally followed.
# Objective
Fixes#12225
Prior to the `bevy_color` port, `GREEN` used to mean "full green." But
it is now a much darker color matching the css1 spec.
## Solution
Change usages of `basic::GREEN` or `css::GREEN` to `LIME` to restore the
examples to their former colors.
This also removes the duplicate definition of `GREEN` from `css`. (it
was already re-exported from `basic`)
## Note
A lot of these examples could use nicer colors. I'm not trying to do
that here.
"Dark Grey" will be tackled separately and has its own tracking issue.
# Objective
Addresses one of the side-notes in #12225.
Colors in the `basic` palette are inconsistent in a few ways:
- `CYAN` was named `AQUA` in the referenced spec. (an alias was added in
a later spec)
- Colors are defined with e.g. "half green" having a `g` value of `0.5`.
But any spec would have been based on 8-bit color, so `0x80 / 0xFF` or
`128 / 255` or ~`0.502`. This precision is likely meaningful when doing
color math/rounding.
## Solution
Regenerate the colors from
https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=37563bedc8858033bd8b8380328c5230
# Objective
- Avoid version mismatch
- When cpal updates oboe in a patch release, this breaks android support
for Bevy
## Solution
- Use the same version of oboe as cpal by relying on it to re-export the
feature
# Objective
Fixes#12310.
#11681 added transformations for bounding volumes, but I accidentally
only added a note in the docs about repeated rotations for `Aabb2d` and
not `Aabb3d`.
## Solution
Copy the docs over to `Aabb3d`.
# Objective
- Describe the objective or issue this PR addresses.
Improve docs around emissive colors --
I couldn't figure out how to increase the emissive strength of
materials, asking on discord @alice-i-cecile told me that color channel
values can go above `1.0` in the case of the `emissive` field. I would
have never figured this out on my own, because [the docs for
emissive](https://docs.rs/bevy/latest/bevy/prelude/struct.StandardMaterial.html#structfield.emissive)
don't mention this possibility, and indeed if you follow the link in the
`emissive` doc [to the `Color`
type](https://docs.rs/bevy/latest/bevy/render/color/enum.Color.html#variants),
you are told that values should be in `[0.0, 1.0]`.
## Solution
- Describe the solution used to achieve the objective above.
Just added a note on the possibility of large color channel values with
example.
# Objective
`initialize_resource<T>` and it's non-send equivalent is only used in
two locations each. Fix#6285.
## Solution
Remove them, replace their calls with their internals. Cut down on a bit
of generic codegen.
This does mean that `initialize_resource_internal` is now `pub(crate)`,
but that's likely OK given that only one variant will remain once
NonSend resources are removed from the World.
# Objective
Follow up to #11600 and #10588https://github.com/bevyengine/bevy/issues/11944 made clear that some
people want to use slicing with texture atlases
## Changelog
* Added support for `TextureAtlas` slicing and tiling.
`SpriteSheetBundle` and `AtlasImageBundle` can now use `ImageScaleMode`
* Added new `ui_texture_atlas_slice` example using a texture sheet

# Objective
When doing a final pass for #3362, it appeared that `ComponentStorage`
as a trait, the two types implementing it, and the associated type on
`Component` aren't really necessary anymore. This likely was due to an
earlier constraint on the use of consts in traits, but that definitely
doesn't seem to be a problem in Rust 1.76.
## Solution
Remove them.
---
## Changelog
Changed: `Component::Storage` has been replaced with
`Component::STORAGE_TYPE` as a const.
Removed: `bevy::ecs::component::ComponentStorage` trait
Removed: `bevy::ecs::component::TableStorage` struct
Removed: `bevy::ecs::component::SparseSetStorage` struct
## Migration Guide
If you were manually implementing `Component` instead of using the
derive macro, replace the associated `Storage` associated type with the
`STORAGE_TYPE` const:
```rust
// in Bevy 0.13
impl Component for MyComponent {
type Storage = TableStorage;
}
// in Bevy 0.14
impl Component for MyComponent {
const STORAGE_TYPE: StorageType = StorageType::Table;
}
```
Component is no longer object safe. If you were relying on `&dyn
Component`, `Box<dyn Component>`, etc. please [file an issue
](https://github.com/bevyengine/bevy/issues) to get [this
change](https://github.com/bevyengine/bevy/pull/12311) reverted.

- Explain it is flushed in the same schedule run (was not obvious to me)
- Point to `apply_deferred` example
- Remove mentions of `System::apply_deferred` and
`Schedule::apply_deferred` which are probably too low level for the most

# Objective
cpal has been updated to [0.15.3](https://crates.io/crates/cpal/0.15.3).
we can remove the skip to avoid check for cpal 0.15.2 dependencies in
deny.toml
cpal now uses ndk 8.0 and Oboe 6.0, so we only have a version for
raw-window-handle, version 0.6
## Solution
- Remove temporal fix that skipped the check for the cpal dependency.
- Update oboe to 0.6
Fixes https://github.com/bevyengine/bevy/issues/11917
# Objective
`bevy_utils::Entry` is only useful when using
`BuildHasherDefault<AHasher>`. It would be great if we didn't have to
write out `bevy_utils::hashbrown::hash_map::Entry` whenever we want to
use a different `BuildHasher`, such as when working with
`bevy_utils::TypeIdMap`.
## Solution
Give `bevy_utils::Entry` a new optional type parameter for defining a
custom `BuildHasher`, such as `NoOpHash`. This parameter defaults to
`BuildHasherDefault<AHasher>`— the `BuildHasher` used by
`bevy_utils::HashMap`.
---
## Changelog
- Added an optional third type parameter to `bevy_utils::Entry` to
specify a custom `BuildHasher`
# Objective
Make it straightforward to translate and rotate bounding volumes.
## Solution
Add `translate_by`/`translated_by`, `rotate_by`/`rotated_by`,
`transform_by`/`transformed_by` methods to the `BoundingVolume` trait.
This follows the naming used for mesh transformations (see #11454 and
#11675).
---
## Changelog
- Added `translate_by`/`translated_by`, `rotate_by`/`rotated_by`,
`transform_by`/`transformed_by` methods to the `BoundingVolume` trait
and implemented them for the bounding volumes
- Renamed `Position` associated type to `Translation`

# Objective
- The doc example for `World::run_system_with_input` mistakenly
indicates that systems share state
- Some of the doc example code is unnecessary and/or could be cleaned up
## Solution
Replace the incorrect result value for the correct one in the doc
example. I also went with an explicit `assert_eq` check as it presents
the same information but can be validated by CI via doc tests.
Also removed some unnecessary code, such as the `Resource` derives on
`Counter`. In fact, I just replaced `Counter` with a `u8` in the
`Local`. I think it makes the example a little cleaner.
---
## Changelog
- Update docs for `World::run_system` and `World::run_system_with_input`
# Objective
- Fixes#12255
Still needs confirming what the consequences are from having camera
viewport nodes live on the root of the taffy tree.
## Solution
To fix calculating the layouts for UI nodes we need to cleanup the
children previously set whenever `TargetCamera` is updated. This also
maintains a list of taffy camera nodes and cleans them up when removed.
---
## Changelog
Fixed#12255
## Migration Guide
changes affect private structs/members so shouldn't need actions by
engine users.
# Objective
Fixes#12126
Notably this does not appear to fix the console error spam that appears
to be coming from winit, only the performance bug that occurs when
tabbing out and back into the game.
## Solution
The winit event loop starts out as `ControlFlow::Wait` by default. When
switching to `UpdateMode::Reactive` or `UpdateMode::ReactiveLowPower`,
we repeatedly update this to `ControlFlow::WaitUntil(next)`. When
switching back to `UpdateMode::Continuous`, the event loop is
erroneously stuck at the latest `ControlFlow::WaitUntil(next)` that was
issued.
I also changed how we handle `Event::NewEvents` since the `StartCause`
already tells us enough information to make that decision. This came
about my debugging and I left it in as an improvement.
# Objective
Resolves#4154
Currently, registration must all be done manually:
```rust
#[derive(Reflect)]
struct Foo(Bar);
#[derive(Reflect)]
struct Bar(Baz);
#[derive(Reflect)]
struct Baz(usize);
fn main() {
// ...
app
.register_type::<Foo>()
.register_type::<Bar>()
.register_type::<Baz>()
// .register_type::<usize>() <- This one is handled by Bevy, thankfully
// ...
}
```
This can grow really quickly and become very annoying to add, remove,
and update as types change. It would be great if we could help reduce
the number of types that a user must manually implement themselves.
## Solution
As suggested in #4154, this PR adds automatic recursive registration.
Essentially, when a type is registered, it may now also choose to
register additional types along with it using the new
`GetTypeRegistration::register_type_dependencies` trait method.
The `Reflect` derive macro now automatically does this for all fields in
structs, tuple structs, struct variants, and tuple variants. This is
also done for tuples, arrays, `Vec<T>`, `HashMap<K, V>`, and
`Option<T>`.
This allows us to simplify the code above like:
```rust
#[derive(Reflect)]
struct Foo(Bar);
#[derive(Reflect)]
struct Bar(Baz);
#[derive(Reflect)]
struct Baz(usize);
fn main() {
// ...
app.register_type::<Foo>()
// ...
}
```
This automatic registration only occurs if the type has not yet been
registered. If it has been registered, we simply skip it and move to the
next one. This reduces the cost of registration and prevents overwriting
customized registrations.
## Considerations
While this does improve ergonomics on one front, it's important to look
at some of the arguments against adopting a PR like this.
#### Generic Bounds
~~Since we need to be able to register the fields individually, we need
those fields to implement `GetTypeRegistration`. This forces users to
then add this trait as a bound on their generic arguments. This
annoyance could be relieved with something like #5772.~~
This is no longer a major issue as the `Reflect` derive now adds the
`GetTypeRegistration` bound by default. This should technically be okay,
since we already add the `Reflect` bound.
However, this can also be considered a breaking change for manual
implementations that left out a `GetTypeRegistration` impl ~~or for
items that contain dynamic types (e.g. `DynamicStruct`) since those also
do not implement `GetTypeRegistration`~~.
#### Registration Assumptions
By automatically registering fields, users might inadvertently be
relying on certain types to be automatically registered. If `Foo`
auto-registers `Bar`, but `Foo` is later removed from the code, then
anywhere that previously used or relied on `Bar`'s registration would
now fail.
---
## Changelog
- Added recursive type registration to structs, tuple structs, struct
variants, tuple variants, tuples, arrays, `Vec<T>`, `HashMap<K, V>`, and
`Option<T>`
- Added a new trait in the hidden `bevy_reflect::__macro_exports` module
called `RegisterForReflection`
- Added `GetTypeRegistration` impl for
`bevy_render::render_asset::RenderAssetUsages`
## Migration Guide
All types that derive `Reflect` will now automatically add
`GetTypeRegistration` as a bound on all (unignored) fields. This means
that all reflected fields will need to also implement
`GetTypeRegistration`.
If all fields **derive** `Reflect` or are implemented in `bevy_reflect`,
this should not cause any issues. However, manual implementations of
`Reflect` that excluded a `GetTypeRegistration` impl for their type will
need to add one.
```rust
#[derive(Reflect)]
struct Foo<T: FromReflect> {
data: MyCustomType<T>
}
// OLD
impl<T: FromReflect> Reflect for MyCustomType<T> {/* ... */}
// NEW
impl<T: FromReflect + GetTypeRegistration> Reflect for MyCustomType<T> {/* ... */}
impl<T: FromReflect + GetTypeRegistration> GetTypeRegistration for MyCustomType<T> {/* ... */}
```

Hi, this is a minimal implementation of #12159. I wasn't sure if the
`EventLoopProxy` should be wrapped somewhat to make it more explicit.
# Objective
Minimal implementation of #12159
When using `UpdateMode::Reactive` it is currently not possible to
request a redraw when a long running task is finished or an external
source has new data.
This makes the following possible which will then run an app update once
``` rust
// EventLoopProxy is Send on most architectures
// The EventLoopProxy can also be saved in a thread local for WASM or a static in other architecturecs
pub fn example(proxy: NonSend<EventLoopProxy<()>>) {
let clone: EventLoopProxy<()> = proxy.clone();
thread::spawn(move || {
// do long work
clone.send_event(());
});
}
```
## Solution
By using the EventLoopProxy one can manually send events from external
threads to the event loop as `UserEvent`s.
This simply sets redraw_requested when a `UserEvent` is received.
## Changelog
- Added the ability to request a redraw from an external source

# Objective
Correct references to `Input` into `ButtonInput` in the keyboard input
docs since it was renamed in 0.13.
## Solution
Change the type used in the keyboard input docs from `Input` to
`ButtonInput`.
# Objective
`Dir3` and `Dir3A` can be rotated using `Quat`s. However, if enough
floating point error accumulates or (more commonly) the rotation itself
is degenerate (like not normalized), the resulting direction can also
become denormalized.
Currently, with debug assertions enabled, it panics in these cases with
the message `rotated.is_normalized()`. This error message is unclear,
doesn't give information about *how* it is denormalized (like is the
length too large, NaN, or something else), and is overall not very
helpful. Panicking for small-ish error might also be a bit too strict,
and has lead to unwanted crashes in crates like `bevy_xpbd` (although it
has also helped in finding actual bugs).
The error message should be clearer and give more context, and it
shouldn't cause unwanted crashes.
## Solution
Change the `debug_assert!` to a warning for small error with a (squared
length) threshold of 2e-4 and a panic for clear error with a threshold
of 2e-2. The warnings mention the direction type and the length of the
denormalized vector.
Here's what the error and warning look like:
```
Error: `Dir3` is denormalized after rotation. The length is 1.014242.
```
```
Warning: `Dir3A` is denormalized after rotation. The length is 1.0001414.
```
I gave the same treatment to `new_unchecked`:
```
Error: The vector given to `Dir3::new_unchecked` is not normalized. The length is 1.014242.
```
```
Warning: The vector given to `Dir3A::new_unchecked` is not normalized. The length is 1.0001414.
```
---
## Discussion
### Threshold values
The thresholds are somewhat arbitrary. 2e-4 is what Glam uses for the
squared length in `is_normalized` (after I corrected it in
bitshifter/glam-rs#480), and 2e-2 is just what I thought could be a
clear sign of something being critically wrong. I can definitely tune
them if there are better thresholds though.
### Logging
`bevy_math` doesn't have `bevy_log`, so we can't use `warn!` or
`error!`. This is why I made it use just `eprintln!` and `panic!` for
now. Let me know if there's a better way of logging errors in
`bevy_math`.
# Objective
In my library,
[`bevy_dev_console`](https://github.com/doonv/bevy_dev_console) I need
access to `App` within `LogPlugin::update_subscriber` in order to
communicate with the `App` from my custom `Layer`.
## Solution
Give access to `App`.
---
## Changelog
- Added access to `App` within `LogPlugin::update_subscriber`
## Migration Guide
`LogPlugin::update_subscriber` now has a `&mut App` parameter. If you
don't need access to `App`, you can ignore the parameter with an
underscore (`_`).
```diff,rust
- fn update_subscriber(subscriber: BoxedSubscriber) -> BoxedSubscriber {
+ fn update_subscriber(_: &mut App, subscriber: BoxedSubscriber) -> BoxedSubscriber {
Box::new(subscriber.with(CustomLayer))
}
```
# Objective
- Allow users to read window events in the sequence they appeared. This
is important for precise input handling when there are multiple input
events in a single frame (e.g. click and release vs release and click).
## Solution
- Add a mega-enum `WinitEvent` that collects window events, and send
those alongside the existing more granular window events.
---
## Changelog
- Added `WinitEvent` event that aggregates all window events into a
synchronized event stream.
# Objective
Fixes https://github.com/bevyengine/bevy/issues/11157.
## Solution
Stop using `BackgroundColor` as a color tint for `UiImage`. Add a
`UiImage::color` field for color tint instead. Allow a UI node to
simultaneously include a solid-color background and an image, with the
image rendered on top of the background (this is already how it works
for e.g. text).
---
## Changelog
- The `BackgroundColor` component now renders a solid-color background
behind `UiImage` instead of tinting its color.
- Removed `BackgroundColor` from `ImageBundle`, `AtlasImageBundle`, and
`ButtonBundle`.
- Added `UiImage::color`.
- Expanded `RenderUiSystem` variants.
- Renamed `bevy_ui::extract_text_uinodes` to `extract_uinodes_text` for
consistency.
## Migration Guide
- `BackgroundColor` no longer tints the color of UI images. Use
`UiImage::color` for that instead.
- For solid color buttons, replace `ButtonBundle { background_color:
my_color.into(), ... }` with `ButtonBundle { image:
UiImage::default().with_color(my_color), ... }`, and update button
interaction systems to use `UiImage::color` instead of `BackgroundColor`
as well.
- `bevy_ui::RenderUiSystem::ExtractNode` has been split into
`ExtractBackgrounds`, `ExtractImages`, `ExtractBorders`, and
`ExtractText`.
- `bevy_ui::extract_uinodes` has been split into
`bevy_ui::extract_uinode_background_colors` and
`bevy_ui::extract_uinode_images`.
- `bevy_ui::extract_text_uinodes` has been renamed to
`extract_uinode_text`.
# Objective
After the `TextureAtlas` changes that landed in 0.13,
`SpriteSheetBundle` is equivalent to `TextureAtlas` + `SpriteBundle` and
`AtlasImageBundle` is equivalent to `TextureAtlas` + `ImageBundle`. As
such, the atlas bundles aren't particularly useful / necessary additions
to the API anymore.
In addition, atlas bundles are inconsistent with `ImageScaleMode` (also
introduced in 0.13) which doesn't have its own version of each image
bundle.
## Solution
Deprecate `SpriteSheetBundle` and `AtlasImageBundle` in favor of
including `TextureAtlas` as a separate component alongside
`SpriteBundle` and `ImageBundle`, respectively.
---
## Changelog
- Deprecated `SpriteSheetBundle` and `AtlasImageBundle`.
## Migration Guide
- `SpriteSheetBundle` has been deprecated. Use `TextureAtlas` alongside
a `SpriteBundle` instead.
- `AtlasImageBundle` has been deprecated. Use `TextureAtlas` alongside
an `ImageBundle` instead.
# Objective
- Part of #9400.
- Add light gizmos for `SpotLight`, `PointLight` and `DirectionalLight`.
## Solution
- Add a `ShowLightGizmo` and its related gizmo group and plugin, that
shows a gizmo for all lights of an entities when inserted on it. Light
display can also be toggled globally through the gizmo config in the
same way it can already be done for `Aabb`s.
- Add distinct segment setters for height and base one `Cone3dBuilder`.
This allow having a properly rounded base without too much edges along
the height. The doc comments explain how to ensure height and base
connect when setting different values.
Gizmo for the three light types without radius with the depth bias set
to -1:
With Radius:
Possible future improvements:
- Add a billboarded sprite with a distinct sprite for each light type.
- Display the intensity of the light somehow (no idea how to represent
that apart from some text).
---
## Changelog
### Added
- The new `ShowLightGizmo`, part of the `LightGizmoPlugin` and
configurable globally with `LightGizmoConfigGroup`, allows drawing gizmo
for `PointLight`, `SpotLight` and `DirectionalLight`. The gizmos color
behavior can be controlled with the `LightGizmoColor` member of
`ShowLightGizmo` and `LightGizmoConfigGroup`.
- The cone gizmo builder (`Cone3dBuilder`) now allows setting a
differing number of segments for the base and height.

# Objective
Bevy's `Dir3` and `Dir3A` only implement `Mul<f32>` and not vice versa,
and `Dir2` can not be multiplied by `f32` at all. They all should
implement multiplication both ways, just like Glam's vector types.
## Solution
Implement `Mul<Dir2>`, `Mul<Dir3>`, and `Mul<Dir3A>` for `f32`, and
`Mul<f32>` for `Dir2`.
# Objective
Adoption of #2104 and #11843. The `Option<usize>` wastes 3-7 bytes of
memory per potential entry, and represents a scaling memory overhead as
the ID space grows.
The goal of this PR is to reduce memory usage without significantly
impacting common use cases.
Co-Authored By: @NathanSWard
Co-Authored By: @tygyh
## Solution
Replace `usize` in `SparseSet`'s sparse array with
`nonmax::NonMaxUsize`. NonMaxUsize wraps a NonZeroUsize, and applies a
bitwise NOT to the value when accessing it. This allows the compiler to
niche the value and eliminate the extra padding used for the `Option`
inside the sparse array, while moving the niche value from 0 to
usize::MAX instead.
Checking the [diff in x86 generated
assembly](6e4da653cc),
this change actually results in fewer instructions generated. One
potential downside is that it seems to have moved a load before a
branch, which means we may be incurring a cache miss even if the element
is not there.
Note: unlike #2104 and #11843, this PR only targets the metadata stores
for the ECS and not the component storage itself. Due to #9907 targeting
`Entity::generation` instead of `Entity::index`, `ComponentSparseSet`
storing only up to `u32::MAX` elements would become a correctness issue.
This will come with a cost when inserting items into the SparseSet, as
now there is a potential for a panic. These cost are really only
incurred when constructing a new Table, Archetype, or Resource that has
never been seen before by the World. All operations that are fairly cold
and not on any particular hotpath, even for command application.
---
## Changelog
Changed: `SparseSet` now can only store up to `usize::MAX - 1` elements
instead of `usize::MAX`.
Changed: `SparseSet` now uses 33-50% less memory overhead per stored
item.
Follow up to #11057
Implemented suggestions from reviewers from: a simpler
fit_canvas_to_parent leads to an explicit CSS setting to the canvas.
From my understanding, it has do be set after wgpu creation due to wgpu
overriding the canvas width/height:
4400a58470/examples/src/utils.rs (L68-L74)
# Changelog
- Re-enable a `fit_canvas_to_parent`, it's removal from
https://github.com/bevyengine/bevy/pull/11057 was problematic. Still,
its inner working is more simple than before: bevy doesn't handle its
resizing, winit does.
## Migration Guide
- Cancels the migration from
https://github.com/bevyengine/bevy/pull/11057
# Objective
Fixes https://github.com/bevyengine/bevy/issues/11628
## Migration Guide
`Command` and `CommandQueue` have migrated from `bevy_ecs::system` to
`bevy_ecs::world`, so `use bevy_ecs::world::{Command, CommandQueue};`
when necessary.
# Objective
Fixes#11298. Make the use of bevy_log vs bevy_utils::tracing more
consistent.
## Solution
Replace all uses of bevy_log's logging macros with the reexport from
bevy_utils. Remove bevy_log as a dependency where it's no longer needed
anymore.
Ideally we should just be using tracing directly, but given that all of
these crates are already using bevy_utils, this likely isn't that great
of a loss right now.
# Objective
bevy_ecs has been developed with a de facto assumption that `Entity` is
to be treated as an opaque identifier by external users, and that its
internal representation is readable but in no way guaranteed to be
stable between versions of bevy_ecs.
This hasn't been clear to users, and the functions on the type that
expose its guts speak a different story.
## Solution
Explicitly document the lack of stability here and define internal
representation changes as a non-breaking change under SemVer. Give it
the same treatment that the standard lib gives `TypeId`.
# Objective
While mucking around with batch_and_prepare systems, it became apparent
that `GpuArrayBufferIndex::index` doesn't need to be a NonMaxU32.
## Solution
Replace it with a normal u32.
This likely has some potential perf benefit by avoiding panics and the
NOT operations, but I haven't been able to find any substantial gains,
so this is primarily for code quality.
---
## Changelog
Changed: `GpuArrayBufferIndex::index` is now a u32.
## Migration Guide
`GpuArrayBuferIndex::index` is now a u32 instead of a `NonMaxU32`.
Remove any calls to `NonMaxU32::get` on the member.
# Objective
- Fix mismatch between the `Component` trait method and the `World`
method.
## Solution
- Replace init_component_info with register_component_hooks.
# Objective
This PR unpins `web-sys` so that unrelated projects that have
`bevy_render` in their workspace can finally update their `web-sys`.
More details in and fixes#12246.
## Solution
* Update `wgpu` from 0.19.1 to 0.19.3.
* Remove the `web-sys` pin.
* Update docs and wasm helper to remove the now-stale
`--cfg=web_sys_unstable_apis` Rust flag.
---
## Changelog
Updated `wgpu` to v0.19.3 and removed `web-sys` pin.
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?
Although we cached hashes of `MeshVertexBufferLayout`, we were paying
the cost of `PartialEq` on `InnerMeshVertexBufferLayout` for every
entity, every frame. This patch changes that logic to place
`MeshVertexBufferLayout`s in `Arc`s so that they can be compared and
hashed by pointer. This results in a 28% speedup in the
`queue_material_meshes` phase of `many_cubes`, with frustum culling
disabled.
Additionally, this patch contains two minor changes:
1. This commit flattens the specialized mesh pipeline cache to one level
of hash tables instead of two. This saves a hash lookup.
2. The example `many_cubes` has been given a `--no-frustum-culling`
flag, to aid in benchmarking.

## Migration guide
* Duplicate `MeshVertexBufferLayout`s are now combined into a single
object, `MeshVertexBufferLayoutRef`, which contains an
atomically-reference-counted pointer to the layout. Code that was using
`MeshVertexBufferLayout` may need to be updated to use
`MeshVertexBufferLayoutRef` instead.
# Objective
- Provide a reliable and performant mechanism to allows users to keep
components synchronized with external sources: closing/opening sockets,
updating indexes, debugging etc.
- Implement a generic mechanism to provide mutable access to the world
without allowing structural changes; this will not only be used here but
is a foundational piece for observers, which are key for a performant
implementation of relations.
## Solution
- Implement a new type `DeferredWorld` (naming is not important,
`StaticWorld` is also suitable) that wraps a world pointer and prevents
user code from making any structural changes to the ECS; spawning
entities, creating components, initializing resources etc.
- Add component lifecycle hooks `on_add`, `on_insert` and `on_remove`
that can be assigned callbacks in user code.
---
## Changelog
- Add new `DeferredWorld` type.
- Add new world methods: `register_component::<T>` and
`register_component_with_descriptor`. These differ from `init_component`
in that they provide mutable access to the created `ComponentInfo` but
will panic if the component is already in any archetypes. These
restrictions serve two purposes:
1. Prevent users from defining hooks for components that may already
have associated hooks provided in another plugin. (a use case better
served by observers)
2. Ensure that when an `Archetype` is created it gets the appropriate
flags to early-out when triggering hooks.
- Add methods to `ComponentInfo`: `on_add`, `on_insert` and `on_remove`
to be used to register hooks of the form `fn(DeferredWorld, Entity,
ComponentId)`
- Modify `BundleInserter`, `BundleSpawner` and `EntityWorldMut` to
trigger component hooks when appropriate.
- Add bit flags to `Archetype` indicating whether or not any contained
components have each type of hook, this can be expanded for other flags
as needed.
- Add `component_hooks` example to illustrate usage. Try it out! It's
fun to mash keys.
## Safety
The changes to component insertion, removal and deletion involve a large
amount of unsafe code and it's fair for that to raise some concern. I
have attempted to document it as clearly as possible and have confirmed
that all the hooks examples are accepted by `cargo miri` as not causing
any undefined behavior. The largest issue is in ensuring there are no
outstanding references when passing a `DeferredWorld` to the hooks which
requires some use of raw pointers (as was already happening to some
degree in those places) and I have taken some time to ensure that is the
case but feel free to let me know if I've missed anything.
## Performance
These changes come with a small but measurable performance cost of
between 1-5% on `add_remove` benchmarks and between 1-3% on `insert`
benchmarks. One consideration to be made is the existence of the current
`RemovedComponents` which is on average more costly than the addition of
`on_remove` hooks due to the early-out, however hooks doesn't completely
remove the need for `RemovedComponents` as there is a chance you want to
respond to the removal of a component that already has an `on_remove`
hook defined in another plugin, so I have not removed it here. I do
intend to deprecate it with the introduction of observers in a follow up
PR.
## Discussion Questions
- Currently `DeferredWorld` implements `Deref` to `&World` which makes
sense conceptually, however it does cause some issues with rust-analyzer
providing autocomplete for `&mut World` references which is annoying.
There are alternative implementations that may address this but involve
more code churn so I have attempted them here. The other alternative is
to not implement `Deref` at all but that leads to a large amount of API
duplication.
- `DeferredWorld`, `StaticWorld`, something else?
- In adding support for hooks to `EntityWorldMut` I encountered some
unfortunate difficulties with my desired API. If commands are flushed
after each call i.e. `world.spawn() // flush commands .insert(A) //
flush commands` the entity may be despawned while `EntityWorldMut` still
exists which is invalid. An alternative was then to add
`self.world.flush_commands()` to the drop implementation for
`EntityWorldMut` but that runs into other problems for implementing
functions like `into_unsafe_entity_cell`. For now I have implemented a
`.flush()` which will flush the commands and consume `EntityWorldMut` or
users can manually run `world.flush_commands()` after using
`EntityWorldMut`.
- In order to allowing querying on a deferred world we need
implementations of `WorldQuery` to not break our guarantees of no
structural changes through their `UnsafeWorldCell`. All our
implementations do this, but there isn't currently any safety
documentation specifying what is or isn't allowed for an implementation,
just for the caller, (they also shouldn't be aliasing components they
didn't specify access for etc.) is that something we should start doing?
(see 10752)
Please check out the example `component_hooks` or the tests in
`bundle.rs` for usage examples. I will continue to expand this
description as I go.
See #10839 for a more ergonomic API built on top of this one that isn't
subject to the same restrictions and supports `SystemParam` dependency
injection.
# Objective
- We introduce a gizmo that displays coordinate axes relative to a
Transform*, primarily for debugging purposes.
- See #9400
## Solution
A new method, `Gizmos::axes`, takes a `Transform`* as input and displays
the standard coordinate axes, transformed according to it; its signature
looks like this:
````rust
pub fn axes(&mut self, transform: into TransformPoint, base_length: f32) { //... }
````
If my carefully placed asterisks hadn't already tipped you off, the
argument here is not actually a `Transform` but instead anything which
implements `TransformPoint`, which allows it to work also with
`GlobalTransform` (and also `Mat4` and `Affine3A`, if the user happens
to be hand-rolling transformations in some way).
The `base_length` parameter is a scaling factor applied to the
coordinate vectors before the transformation takes place; in other
words, the caller can use this to help size the coordinate axes
appropriately for the entity that they are attached to.
An example invocation of this method looks something like this:
````rust
fn draw_axes_system(
mut gizmos: Gizmos,
query: Query<&Transform, With<MyMarkerComponent>>,
) {
for &transform in &query {
gizmos.axes(transform, 2.);
}
}
````
The result is the three coordinate axes, X, Y, Z (colored red, green,
and blue, respectively), drawn onto the entity:

src="https://github.com/bevyengine/bevy/assets/2975848/789d1703-29ae-4295-80ab-b87459cf8037">
Note that, if scaling was applied as part of the given transformation,
it shows up in scaling on the axes as well:

---
## Changelog
- Added `Gizmos::axes` in bevy_gizmos/src/arrows.rs
- Fixed a minor issue with `ArrowBuilder::with_tip_length` not correctly
implementing builder style (no external impact)
---
## Discussion
### Design considerations
I feel pretty strongly that having no default length scale is for the
best, at least for the time being, since it's very easy for the length
scale to be too small, leading to the axes being hidden inside the body
of the object they are associated with. That is, if the API instead
looked like this:
````rust
gizmos.axes(transform); // or
gizmos.axes(transform).with_length_scale(3.0);
````
then I think it's a reasonable expectation that the first thing would
"just work" for most applications, and it wouldn't, which would be kind
of a footgun.
### Future steps
There are a few directions that this might expand in the future:
1. Introduce additional options via the standard builder pattern; i.e.
introducing `AxesBuilder<T: TransformPoint>` so that people can
configure the axis colors, normalize all axes to a fixed length
independent of scale deformations, etc.
2. Fold this functionality into a plugin (like AabbGizmoPlugin) so that
the functionality becomes more-or-less automatic based on certain fixed
marker components. This wouldn't be very hard to implement, and it has
the benefit of making the axes more frictionless to use. Furthermore, if
we coupled this to the AABB functionality we already have, we could also
ensure that the plugin automatically sizes the axes (by coupling their
size to the dimensions of the AABB, for example).
3. Implement something similar for 2d. Honestly, I have no idea if this
is desired/useful, but I could probably just implement it in this PR if
that's the case.
# Objective
- As part of the migration process we need to a) see the end effect of
the migration on user ergonomics b) check for serious perf regressions
c) actually migrate the code
- To accomplish this, I'm going to attempt to migrate all of the
remaining user-facing usages of `LegacyColor` in one PR, being careful
to keep a clean commit history.
- Fixes#12056.
## Solution
I've chosen to use the polymorphic `Color` type as our standard
user-facing API.
- [x] Migrate `bevy_gizmos`.
- [x] Take `impl Into<Color>` in all `bevy_gizmos` APIs
- [x] Migrate sprites
- [x] Migrate UI
- [x] Migrate `ColorMaterial`
- [x] Migrate `MaterialMesh2D`
- [x] Migrate fog
- [x] Migrate lights
- [x] Migrate StandardMaterial
- [x] Migrate wireframes
- [x] Migrate clear color
- [x] Migrate text
- [x] Migrate gltf loader
- [x] Register color types for reflection
- [x] Remove `LegacyColor`
- [x] Make sure CI passes
Incidental improvements to ease migration:
- added `Color::srgba_u8`, `Color::srgba_from_array` and friends
- added `set_alpha`, `is_fully_transparent` and `is_fully_opaque` to the
`Alpha` trait
- add and immediately deprecate (lol) `Color::rgb` and friends in favor
of more explicit and consistent `Color::srgb`
- standardized on white and black for most example text colors
- added vector field traits to `LinearRgba`: ~~`Add`, `Sub`,
`AddAssign`, `SubAssign`,~~ `Mul<f32>` and `Div<f32>`. Multiplications
and divisions do not scale alpha. `Add` and `Sub` have been cut from
this PR.
- added `LinearRgba` and `Srgba` `RED/GREEN/BLUE`
- added `LinearRgba_to_f32_array` and `LinearRgba::to_u32`
## Migration Guide
Bevy's color types have changed! Wherever you used a
`bevy::render::Color`, a `bevy::color::Color` is used instead.
These are quite similar! Both are enums storing a color in a specific
color space (or to be more precise, using a specific color model).
However, each of the different color models now has its own type.
TODO...
- `Color::rgba`, `Color::rgb`, `Color::rbga_u8`, `Color::rgb_u8`,
`Color::rgb_from_array` are now `Color::srgba`, `Color::srgb`,
`Color::srgba_u8`, `Color::srgb_u8` and `Color::srgb_from_array`.
- `Color::set_a` and `Color::a` is now `Color::set_alpha` and
`Color::alpha`. These are part of the `Alpha` trait in `bevy_color`.
- `Color::is_fully_transparent` is now part of the `Alpha` trait in
`bevy_color`
- `Color::r`, `Color::set_r`, `Color::with_r` and the equivalents for
`g`, `b` `h`, `s` and `l` have been removed due to causing silent
relatively expensive conversions. Convert your `Color` into the desired
color space, perform your operations there, and then convert it back
into a polymorphic `Color` enum.
- `Color::hex` is now `Srgba::hex`. Call `.into` or construct a
`Color::Srgba` variant manually to convert it.
- `WireframeMaterial`, `ExtractedUiNode`, `ExtractedDirectionalLight`,
`ExtractedPointLight`, `ExtractedSpotLight` and `ExtractedSprite` now
store a `LinearRgba`, rather than a polymorphic `Color`
- `Color::rgb_linear` and `Color::rgba_linear` are now
`Color::linear_rgb` and `Color::linear_rgba`
- The various CSS color constants are no longer stored directly on
`Color`. Instead, they're defined in the `Srgba` color space, and
accessed via `bevy::color::palettes::css`. Call `.into()` on them to
convert them into a `Color` for quick debugging use, and consider using
the much prettier `tailwind` palette for prototyping.
- The `LIME_GREEN` color has been renamed to `LIMEGREEN` to comply with
the standard naming.
- Vector field arithmetic operations on `Color` (add, subtract, multiply
and divide by a f32) have been removed. Instead, convert your colors
into `LinearRgba` space, and perform your operations explicitly there.
This is particularly relevant when working with emissive or HDR colors,
whose color channel values are routinely outside of the ordinary 0 to 1
range.
- `Color::as_linear_rgba_f32` has been removed. Call
`LinearRgba::to_f32_array` instead, converting if needed.
- `Color::as_linear_rgba_u32` has been removed. Call
`LinearRgba::to_u32` instead, converting if needed.
- Several other color conversion methods to transform LCH or HSL colors
into float arrays or `Vec` types have been removed. Please reimplement
these externally or open a PR to re-add them if you found them
particularly useful.
- Various methods on `Color` such as `rgb` or `hsl` to convert the color
into a specific color space have been removed. Convert into
`LinearRgba`, then to the color space of your choice.
- Various implicitly-converting color value methods on `Color` such as
`r`, `g`, `b` or `h` have been removed. Please convert it into the color
space of your choice, then check these properties.
- `Color` no longer implements `AsBindGroup`. Store a `LinearRgba`
internally instead to avoid conversion costs.

# Objective
Just some mild annoyances:
- The `Color::Oklaba`, `Color::Oklcha` and `oklaba::Oklaba` doc comments
were inconsistent with the others
- The crate-level docs didn't include `Oklch` in the list of
representations and misspelt it in a later paragraph
## Solution
- Fix 'em
# Objective
- Cull 2D text outside the view frustum.
- Part of #11081.
## Solution
- Compute AABBs for entities with a `Text2DBundle` to enable culling
them.
`text2d` example with AABB gizmos on the text entities:
https://github.com/bevyengine/bevy/assets/18357657/52ed3ddc-2274-4480-835b-a7cf23338931
---
## Changelog
### Added
- 2D text outside the view are now culled with the
`calculate_bounds_text2d` system adding the necessary AABBs.
# Objective
`bevy_tasks` provides utilities for parallel mapping over slices. It can
be useful to have a chunk index available in the iteration function to
know which part of the original slice is being processed.
## Solution
Adds an index argument to the parallel map functions in `bevy_tasks`.
---
## Changelog
### Changed
- `par_chunk_map`, `par_splat_map`, `par_chunk_map_mut`, and
`par_splat_map_mut` now provide a chunk index during iteration.
## Migration Guide
Functions passed as arguments to `par_chunk_map`, `par_splat_map`,
`par_chunk_map_mut`, and `par_splat_map_mut` must now take an additional
index argument.
# Objective
Split up from #12017, rename Bevy's direction types.
Currently, Bevy has the `Direction2d`, `Direction3d`, and `Direction3dA`
types, which provide a type-level guarantee that their contained vectors
remain normalized. They can be very useful for a lot of APIs for safety,
explicitness, and in some cases performance, as they can sometimes avoid
unnecessary normalizations.
However, many consider them to be inconvenient to use, and opt for
standard vector types like `Vec3` because of this. One reason is that
the direction type names are a bit long and can be annoying to write (of
course you can use autocomplete, but just typing `Vec3` is still nicer),
and in some intances, the extra characters can make formatting worse.
The naming is also inconsistent with Glam's shorter type names, and
results in names like `Direction3dA`, which (in my opinion) are
difficult to read and even a bit ugly.
This PR proposes renaming the types to `Dir2`, `Dir3`, and `Dir3A`.
These names are nice and easy to write, consistent with Glam, and work
well for variants like the SIMD aligned `Dir3A`. As a bonus, it can also
result in nicer formatting in a lot of cases, which can be seen from the
diff of this PR.
Some examples of what it looks like: (copied from #12017)
```rust
// Before
let ray_cast = RayCast2d::new(Vec2::ZERO, Direction2d::X, 5.0);
// After
let ray_cast = RayCast2d::new(Vec2::ZERO, Dir2::X, 5.0);
```
```rust
// Before (an example using Bevy XPBD)
let hit = spatial_query.cast_ray(
Vec3::ZERO,
Direction3d::X,
f32::MAX,
true,
SpatialQueryFilter::default(),
);
// After
let hit = spatial_query.cast_ray(
Vec3::ZERO,
Dir3::X,
f32::MAX,
true,
SpatialQueryFilter::default(),
);
```
```rust
// Before
self.circle(
Vec3::new(0.0, -2.0, 0.0),
Direction3d::Y,
5.0,
Color::TURQUOISE,
);
// After (formatting is collapsed in this case)
self.circle(Vec3::new(0.0, -2.0, 0.0), Dir3::Y, 5.0, Color::TURQUOISE);
```
## Solution
Rename `Direction2d`, `Direction3d`, and `Direction3dA` to `Dir2`,
`Dir3`, and `Dir3A`.
---
## Migration Guide
The `Direction2d` and `Direction3d` types have been renamed to `Dir2`
and `Dir3`.
## Additional Context
This has been brought up on the Discord a few times, and we had a small
[poll](https://discord.com/channels/691052431525675048/1203087353850364004/1212465038711984158)
on this. `Dir2`/`Dir3`/`Dir3A` was quite unanimously chosen as the best
option, but of course it was a very small poll and inconclusive, so
other opinions are certainly welcome too.

# Objective
- Fixes#12170
## Solution
- Moved the existing `color_from_entity` internals into
`Hsla::sequence_dispersed` which generates a randomly distributed but
deterministic color sequence based.
- Replicated the method for `Lcha` and `Oklcha` as well.
## Examples
### Getting a few colours for a quick palette
```rust
let palette = Hsla::sequence_dispersed().take(5).collect::<Vec<_>>();
/*[
Hsla::hsl(0.0, 1., 0.5),
Hsla::hsl(222.49225, 1., 0.5),
Hsla::hsl(84.984474, 1., 0.5),
Hsla::hsl(307.4767, 1., 0.5),
Hsla::hsl(169.96895, 1., 0.5),
]*/
```
### Getting a colour from an `Entity`
```rust
let color = Oklcha::sequence_dispersed().nth(entity.index() as u32).unwrap();
```
## Notes
This was previously a private function exclusively for `Entity` types.
I've decided it should instead be public and operate on a `u32`
directly, since this function may have broader uses for debugging
purposes.

# Objective
fix#12182
- extract (or default) target camera for ui material nodes in the same
way as for other material nodes
- render ui material nodes only to their specified target
# Objective
Improve the `bevy::math::cubic_splines` module by making it more
flexible and adding new curve types.
Closes#10220
## Solution
Added new spline types and improved existing
---
## Changelog
### Added
- `CubicNurbs` rational cubic curve generator, allows setting the knot
vector and weights associated with every point
- `LinearSpline` curve generator, allows generating a linearly
interpolated curve segment
- Ability to push additional cubic segments to `CubicCurve`
- `IntoIterator` and `Extend` implementations for `CubicCurve`
### Changed
- `Point` trait has been implemented for more types: `Quat` and `Vec4`.
- `CubicCurve::coefficients` was moved to `CubicSegment::coefficients`
because the function returns `CubicSegment`, so it seems logical to be
associated with `CubicSegment` instead. The method is still not public.
### Fixed
- `CubicBSpline::new` was referencing Cardinal spline instead of
B-Spline

# Objective
- #12165 recently added links to Bevy errors in error messages.
- The links were in the form of `See:
https://bevyengine.org/learn/errors/#b000N`
- B0004 does not have the colon separating `See` and the link, unlike
the rest of the error messages
## Solution
- Add a colon, for consistency :)
# Objective
- More reflection
## Solution
- More. Reflection.
(not sure what bevy's policy on `derive(Debug)` is given that reflection
already lets you accomplish something largely equivalent; maybe
`derive(Reflect)` should generate a `Debug` impl that goes through
`Reflect::debug` unless you opt out?)
# Objective
The `css` contains all of the `basic` colors. Rather than defining them
twice, we can re-export them.
Suggested by @viridia <3
## Solution
- Re-export basic color palette within the css color palette.
- Remove the duplicate colors
- Fix alphabetization of the basic color palette file while I'm here

# Objective
- Complete compatibility with CSS Module 4
## Solution
- Added `Oklcha` which implements the Oklch color model.
- Updated `Color` and `LegacyColor` accordingly.
## Migration Guide
- Convert `Oklcha` to `Oklaba` using the provided `From` implementations
and then handle accordingly.
## Notes
This is the _last_ color space missing from the CSS Module 4 standard,
and is also the one I believe we should recommend users actually work
with for hand-crafting colours. It has all the uniformity benefits of
Oklab combined with the intuition chroma and hue provide (when compared
to a-axis and b-axis parameters).
# Objective
- Implement grid gizmos, suggestion of #9400
## Solution
- Added `gizmos.grid(...) ` and `gizmos.grid_2d(...)`
- The grids may be configured using `.outer_edges(...)` to specify
whether to draw the outer border/edges of the grid and `.skew(...)`to
specify the skew of the grid along the x or y directions.
---
## Changelog
- Added a `grid` module to `bevy_gizmos` containing `gizmos.grid(...) `
and `gizmos.grid_2d(...)` as well as assorted items.
- Updated the `2d_gizmos` and `3d_gizmos` examples to use grids.
## Additional
The 2D and 3D examples now look like this:

# Objective
As suggested in #12163 by @cart, we should add convenience constructors
to `bevy_color::Color` to match the existing API (easing migration pain)
and generally improve ergonomics.
## Solution
- Add `const fn Color::rgba(red, green, blue, alpha)` and friends, which
directly construct the appropriate variant.
- Add `const fn Color::rgb(red, green, blue)` and friends, which impute
and alpha value of 1.0.
- Add `const BLACK, WHITE, NONE` to `Color`. These are stored in
`LinearRgba` to reduce pointless conversion costs and inaccuracy.
- Changed the default `Color` from `Srgba::WHITE` to the new linear
equivalent for the same reason.

# Objective
As we start to migrate to `bevy_color` in earnest (#12056), we should
make it visible to Bevy users, and usable in examples.
## Solution
1. Add a prelude to `bevy_color`: I've only excluded the rarely used
`ColorRange` type and the testing-focused color distance module. I
definitely think that some color spaces are less useful than others to
end users, but at the same time the types used there are very unlikely
to conflict with user-facing types.
2. Add `bevy_color` to `bevy_internal` as an optional crate.
3. Re-export `bevy_color`'s prelude as part of `bevy::prelude`.

# Objective
- In #9623 I forgot to change the `FromWorld` requirement for
`ReflectResource`, fix that;
- Fix#12129
## Solution
- Use the same approach as in #9623 to try using `FromReflect` and
falling back to the `ReflectFromWorld` contained in the `TypeRegistry`
provided
- Just reflect `Resource` on `State<S>` since now that's possible
without introducing new bounds.
---
## Changelog
- `ReflectResource`'s `FromType<T>` implementation no longer requires
`T: FromWorld`, but instead now requires `FromReflect`.
- `ReflectResource::insert`, `ReflectResource::apply_or_insert` and
`ReflectResource::copy` now take an extra `&TypeRegistry` parameter.
## Migration Guide
- Users of `#[reflect(Resource)]` will need to also implement/derive
`FromReflect` (should already be the default).
- Users of `#[reflect(Resource)]` may now want to also add `FromWorld`
to the list of reflected traits in case their `FromReflect`
implementation may fail.
- Users of `ReflectResource` will now need to pass a `&TypeRegistry` to
its `insert`, `apply_or_insert` and `copy` methods.
# Objective
`downcast-rs` is not used within bevy_ecs. This is probably a remnant
from before Schedule v3 landed, since stages needed the downcasting.
## Solution
Remove it.
Shows relationships between color spaces and explains what files should
contain which conversions.
# Objective
- Provide documentation for maintainers and users on how color space
conversion is implemented.
## Solution
- Created a mermaid diagram documenting the relationships between
various color spaces. This diagram also includes links to defining
articles, and edges include links to conversion formulae.
- Added a `conversion.md` document which is included in the
documentation of each of the color spaces. This ensures it is readily
visible in all relevant contexts.
## Notes
The diagram is in the Mermaid (`.mmd`) format, and must be converted
into an SVG file (or other image format) prior to use in Rust
documentation. I've included a link to
[mermaid.live](https://mermaid.live) as an option for doing such
conversion in an appropriate README.
Below is a screenshot of the documentation added.
# Objective
`FromWorld` is often used to group loading and creation of assets for
resources.
With this setup, users often end up repetitively calling
`.resource::<AssetServer>` and `.resource_mut::<Assets<T>>`, and may
have difficulties handling lifetimes of the returned references.
## Solution
Add extension methods to `World` to add and load assets, through a new
extension trait defined in `bevy_asset`.
### Other considerations
* This might be a bit too "magic", as it makes implicit the resource
access.
* We could also implement `DirectAssetAccessExt` on `App`, but it didn't
feel necessary, as `FromWorld` is the principal use-case here.
---
## Changelog
* Add the `DirectAssetAccessExt` trait, which adds the `add_asset`,
`load_asset` and `load_asset_with_settings` method to the `World` type.
# Objective
This PR arose as part of the migration process for `bevy_color`: see
#12056.
While examining how `bevy_gizmos` stores color types internally, I found
that rather than storing a `Color` internally, it actually stores a
`[f32;4]` for a linear RGB, type aliased to a `ColorItem`.
While we don't *have* to clean this up to complete the migration, now
that we have explicit strong typing for linear color types we should use
them rather than replicating this idea throughout the codebase.
## Solution
- Added `LinearRgba::NAN`, for when you want to do cursed rendering
things.
- Replaced the internal color representation in `bevy_gizmo`: this was
`ColorItem`, but is now `LinearRgba`.
- `LinearRgba` is now `Pod`, enabling us to use the same fast `bytemuck`
bit twiddling tricks that we were using before. This requires:
1. Forcing `LinearRgba` to be `repr(C)`
2. Implementing `Zeroable`, and unsafe trait which defines what the
struct looks like when all values are zero.
3. Implementing `Pod`, a marker trait with stringent safety requirements
that is required for "plain old data".

# Objective
- Improve compatibility with CSS Module 4
- Simplify `Lcha` conversion functions
## Solution
- Added `Laba` which implements the Lab color model.
- Updated `Color` and `LegacyColor` accordingly.
## Migration Guide
- Convert `Laba` to either `Xyza` or `Lcha` using the provided `From`
implementations and then handle accordingly.
## Notes
The Lab color space is a required stepping stone when converting between
XYZ and Lch, therefore we already use the Lab color model, just in an
nameless fashion prone to errors.
This PR also includes a slightly broader refactor of the `From`
implementations between the various colour spaces to better reflect the
graph of definitions. My goal was to keep domain specific knowledge of
each colour space contained to their respective files (e.g., the
`From<Oklaba> for LinearRgba` definition was in `linear_rgba.rs` when it
probably belongs in `oklaba.rs`, since Linear sRGB is a fundamental
space and Oklab is defined in its relation to it)
# Objective
The `AssetIndex` cannot be carried across boundaries that do not allow
explicit rust types.
For context, I ran into this issue while trying to implent an
improvement for bevy_egui which leverages the not-so-new custom loader
API. Passing through a handle directly isn't possible, but instead it
requires stringified URI s. I had to work around the lack of this API s
existance using reflection, which is rather dirty.
## Solution
- Add `to_bits` and `from_bits` functions to `AssetIndex` to allow
moving this type through such boundaries.

# Objective
- Make these types usable in reflection-based workflows.
## Solution
- The usual. Also reflect `Default` and `Component` behaviors so that
the types can be constructed, inserted, and removed.
# Objective
Added reflect support for `std::HashSet`, `BTreeSet` and `BTreeMap`.
The set support is limited to `reflect_value` since that's the level of
support prior art `bevy_util::HashSet` got.
## Changelog
Dropped `Hash` Requirement on `MapInfo` since it's not needed on
`BTreeMap`s.
# Objective
Memory usage optimisation
## Solution
`HashMap` and `HashSet`'s keys are immutable. So using mutable types
like `String`, `Vec<T>`, or `PathBuf` as a key is a waste of memory:
they have an extra `usize` for their capacity and may have spare
capacity.
This PR replaces these types by their immutable equivalents `Box<str>`,
`Box<[T]>`, and `Box<Path>`.
For more context, I recommend watching the [Use Arc Instead of
Vec](https://www.youtube.com/watch?v=A4cKi7PTJSs) video.

# Objective
- Avoid misspellings throughout the codebase by using
[`typos`](https://github.com/crate-ci/typos) in CI
Inspired by https://github.com/gfx-rs/wgpu/pull/5191
Typos is a minimal code speller written in rust that finds and corrects
spelling mistakes among source code.
- Fast enough to run on monorepos
- Low false positives so you can run on PRs
## Solution
- Use
[typos-action](https://github.com/marketplace/actions/typos-action) in
CI
- Add how to use typos in the Contribution Guide

# Objective
- Fixes#12001.
- Note this PR doesn't change any feature flags, however flaky the issue
revealed they are.
## Solution
- Use `FromReflect` to convert proxy types to concrete ones in
`ReflectSerialize::get_serializable`.
- Use `get_represented_type_info() -> type_id()` to get the correct type
id to interact with the registry in
`bevy_reflect::serde::ser::get_serializable`.
---
## Changelog
- Registering `ReflectSerialize` now imposes additional `FromReflect`
and `TypePath` bounds.
## Migration Guide
- If `ReflectSerialize` is registered on a type, but `TypePath` or
`FromReflect` implementations are omitted (perhaps by
`#[reflect(type_path = false)` or `#[reflect(from_reflect = false)]`),
the traits must now be implemented.

# Objective
Fix#11845.
## Solution
Remove the `UpdateAssets` and `AssetEvents` schedules. Moved the
`UpdateAssets` systems to `PreUpdate`, and `AssetEvents` systems into
`First`. The former is meant to run before any of the event flushes.
## Future Work
It'd be ideal if we could manually flush the events for assets to avoid
needing two, sort of redundant, systems. This should at least let them
potentially run in parallel with all of the systems in the schedules
they were moved to.
---
## Changelog
Removed: `UpdateAssets` schedule from the main schedule. All systems
have been moved to `PreUpdate`.
Removed: `AssetEvents` schedule from the main schedule. All systems have
been move to `First` with the same system sets.
## Migration Guide
TODO
# Objective
- Partially addresses https://github.com/bevyengine/bevy/issues/11470
(I'd like to add Spatiotemporal Blue Noise in the future, but that's a
bit more controversial).
- Fix cluster_debug_visualization which has not compiled for a while
---
## Changelog
- Added random white noise shader functions to `bevy_pbr::utils`
## Migration Guide
- The `bevy_pbr::utils::random1D` shader function has been replaced by
the similar `bevy_pbr::utils::rand_f`.
# Objective
- During rendering of different gizmo groups, the ordering is random
between executions
## Solution
- Make the ordering stable
- It's using a `TypeIdMap`, its iteration order depends on the insertion
order. so insert when adding a group instead of when adding a gizmo
- Also changed `extract_gizmo_data` to not be group dependent. there
will be only one of those systems, no matter the number of gizmo groups
added

# Objective
`CameraProjectionPlugin<T>`'s bounds are `T: CameraProjection`. But the
bounds for `CameraProjectionPlugin` implementing `Plugin` are `T:
CameraProjection + Component + GetTypeRegistration`. This means that if
`T` is valid for `CameraProjectionPlugin`'s bounds, but not the plugin
implementation's bounds, then `CameraProjectionPlugin` would not
implement `Plugin`. Which is weird because you'd expect a struct with
`Plugin` in the name to implement `Plugin`.
## Solution
Make `CameraProjectionPlugin<T>`'s bounds `T: CameraProjection +
Component + GetTypeRegistration`. I also rearranged some of the code.
---
## Changelog
- Changed `CameraProjectionPlugin<T>`'s bounds to `T: CameraProjection +
Component + GetTypeRegistration`
## Migration Guide
`CameraProjectionPlugin<T>`'s trait bounds now require `T` to implement
`CameraProjection`, `Component`, and `GetTypeRegistration`. This
shouldn't affect most existing code as `CameraProjectionPlugin<T>` never
implemented `Plugin` unless those bounds were met.
# Objective
Split up from #12017, add an aligned version of `Direction3d` for SIMD,

## Solution
Add `Direction3dA` and move direction types into a new `direction`
module.

## Migration Guide
The `Direction2d`, `Direction3d`, and `InvalidDirectionError` types have
been moved out of `bevy::math::primitives`.
Before:
```rust
use bevy::math::primitives::Direction3d;
```
After:
```rust
use bevy::math::Direction3d;

# Objective
- Improve compatibility with CSS Module 4
- Simplify `Hsla` conversion functions
## Solution
- Added `Hsva` which implements the HSV color model.
- Added `Hwba` which implements the HWB color model.
- Updated `Color` and `LegacyColor` accordingly.
## Migration Guide
- Convert `Hsva` / `Hwba` to either `Hsla` or `Srgba` using the provided
`From` implementations and then handle accordingly.
## Notes
While the HSL color space is older than HWB, the formulation for HWB is
more directly related to RGB. Likewise, HSV is more closely related to
HWB than HSL. This makes the conversion of HSL to/from RGB more
naturally represented as the compound operation HSL <-> HSV <-> HWB <->
RGB. All `From` implementations for HSL, HSV, and HWB have been designed
to take the shortest path between itself and the target space.

# Objective
- We should move towards a consistent use of the new `bevy_color` crate.
- As discussed in #12089, splitting this work up into small pieces makes
it easier to review.
## Solution
- Port all uses of `LegacyColor` in the `bevy_core_pipeline` to
`LinearRgba`
- `LinearRgba` is the correct type to use for internal rendering types
- Added `LinearRgba::BLACK` and `WHITE` (used during migration)
- Add `LinearRgba::grey` to more easily construct balanced grey colors
(used during migration)
- Add a conversion from `LinearRgba` to `wgpu::Color`. The converse was
not done at this time, as this is typically a user error.
I did not change the field type of the clear color on the cameras: as
this is user-facing, this should be done in concert with the other
configurable fields.
## Migration Guide
`ColorAttachment` now stores a `LinearRgba` color, rather than a Bevy
0.13 `Color`.
`set_blend_constant` now takes a `LinearRgba` argument, rather than a
Bevy 0.13 `Color`.

# Objective
Right now when using egui, systems are inserted without any identifier
and to the root. I'd like to name those systems and insert them as

depicted above benefit from tear down of the abstraction.

# Objective
The multi-threaded executor currently runs in a dedicated task on a
single thread. When a system finishes running, it needs to notify that
task and wait for the thread to be available and running before the
executor can process the completion.
See #8304
## Solution
Run the multi-threaded executor at the end of each system task. This
allows it to run immediately instead of needing to wait for the main
thread to wake up. Move the mutable executor state into a separate
struct and wrap it in a mutex so it can be shared among the worker
threads.
While this should be faster in theory, I don't actually know how to
measure the performance impact myself.

# Objective
Partially address #888. Gilrs is initialized on a separate thread, and
thus conditionally implements `Send`, and all platforms other than Wasm.
This means the `NonSend` resource constraint is likely too conservative.
## Solution
Relax the requirement, and conditionally derive Resource on a wrapper
around it, using `SyncCell` to satisfy the `Sync` requirement on it.
# Objective
- Fixes#12081
## Solution
Passing the `Affine2` as a neatly packed `mat3x2` breaks WebGL with
`drawElementsInstanced: Buffer for uniform block is smaller than
UNIFORM_BLOCK_DATA_SIZE.`
I fixed this by using a `mat3x3` instead.
Alternative solutions that come to mind:
- Pass in a `mat3x2` on non-webgl targets and a `mat3x3` otherwise. I
guess I could use `#ifdef SIXTEEN_BYTE_ALIGNMENT` for this, but it
doesn't seem quite right? This would be more efficient, but decrease
code quality.
- Do something about `UNIFORM_BLOCK_DATA_SIZE`. I don't know how, so I'd
need some guidance here.
@superdump let me know if you'd like me to implement other variants.
Otherwise, I vote for merging this as a quick fix for `main` and then
improving the packing in subsequent PRs :)
## Additional notes
Ideally we should merge this before @JMS55 rebases #10164 so that they
don't have to rebase everything a second time.
# Objective
- Fixes#12068
## Solution
- Split `bevy_render::color::colorspace` across the various space
implementations in `bevy_color` as appropriate.
- Moved `From` implementations involving

# Objective
- The bloom effect is currently somewhat costly (in terms of GPU time
used), due to using fragment shaders for down- and upscaling (compute
shaders generally perform better for such tasks).
- Additionally, one might have a `BloomSettings` on a camera whose
`intensity` is only occasionally set to a non-zero value (eg. in outside
areas or areas with bright lighting). Currently, the cost of the bloom
shader is always incurred as long as the `BloomSettings` exists.
## Solution
- Bail out of the bloom render node when `intensity == 0.0`, making the
effect free as long as it is turned all the way down.
# Objective
- Fixes#751
## Solution
- Added `PluginGroupBuilder::add_group`, which accepts an owned `impl
PluginGroup` and adds those plugins to self, following
`PluginGroupBuilder::add`'s replacement rules.
- Split `PluginGroupBuilder::upsert_plugin_state` into two functions,
one of the same name, and
`PluginGroupBuilder::upsert_plugin_entry_state` which takes a
`PluginEntry` and `TypeId` directly. This allows for shared behaviour
between `add` and `add_group`.
- Added 2 unit tests documenting the replacement behaviour in
`PluginGroupBuilder::add_group`.

# Objective
#7348 added `bevy_utils::Parallel` and replaced the usage of the
`ThreadLocal<Cell<Vec<...>>>` in `check_visibility`, but we were also
using it in `extract_meshes`.
## Solution
Refactor the system to use `Parallel` instead.
# Objective
The physical width and height (pixels) of an image is always integers,
but for `GpuImage` bevy currently stores them as `Vec2` (`f32`).
Switching to `UVec2` makes this more consistent with the [underlying
texture data](https://docs.rs/wgpu/latest/wgpu/struct.Extent3d.html).
I'm not sure if this is worth the change in the surface level API. If
not, feel free to close this PR.
## Solution
- Replace uses of `Vec2` with `UVec2` when referring to texture
dimensions.
- Use integer types for the texture atlas dimensions and sections.
[`Sprite::rect`](a81a2d1da3/crates/bevy_sprite/src/sprite.rs (L29))
remains unchanged, so manually specifying a sub-pixel region of an image
is still possible.
---
## Changelog
- `GpuImage` now stores its size as `UVec2` instead of `Vec2`.
- Texture atlases store their size and sections as `UVec2` and `URect`
respectively.
- `UiImageSize` stores its size as `UVec2`.
## Migration Guide
- Change floating point types (`Vec2`, `Rect`) to their respective
unsigned integer versions (`UVec2`, `URect`) when using `GpuImage`,
`TextureAtlasLayout`, `TextureAtlasBuilder`,
`DynamicAtlasTextureBuilder` or `FontAtlas`.
# Objective
- I hit an issue using the `file_watcher` feature to hot reload assets
for my game. The change in this PR allows me to now hot reload assets.
- The issue stemmed from my project being a multi crate workspace
project structured like so:
```
└── my_game
├── my_game_core
│ ├── src
│ └── assets
├── my_game_editor
│ └── src/main.rs
└── my_game
└── src/main.rs
```
- `my_game_core` is a crate that holds all my game logic and assets
- `my_game` is the crate that creates the binary for my game (depends on
the game logic and assets in `my_game_core`)
- `my_game_editor` is an editor tool for my game (it also depends on the
game logic and assets in `my_game_core`)
Whilst running `my_game` and `my_game_editor` from cargo during
development I would use `AssetPlugin` like so:
```rust
default_plugins.set(AssetPlugin {
watch_for_changes_override: Some(true),
file_path: "../my_game_core/assets".to_string(),
..Default::default()
})
```
This works fine; bevy picks up the assets. However on saving an asset I
would get the following panic from `file_watcher`. It wouldn't kill the
app, but I wouldn't see the asset hot reload:
```
thread 'notify-rs debouncer loop' panicked at /Users/ian/.cargo/registry/src/index.crates.io-6f17d22bba15001f/bevy_asset-0.12.1/src/io/file/file_watcher.rs:48:58:
called `Result::unwrap()` on an `Err` value: StripPrefixError(())
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
```
## Solution
- The solution is to collapse dot segments in the root asset path
`FileWatcher` is using
- There was already bevy code to do this in `AssetPath`, so I extracted
that code so it could be reused in `FileWatcher`
# Objective

# Objective
- Sometimes, it is useful to get a `Handle<T>` from an `AssetId<T>`. For
example, when iterating `Assets` to find a specific asset. So much so
that it's possible to do so with `AssetServer::get_id_handle`
- However, `AssetServer::get_id_handle` doesn't work with assets
directly added to `Assets` using `Assets::add`.
- Fixes#12087
## Solution
- Add `Assets::get_strong_handle` to convert an `AssetId` into an
`Handle`
- Document `AssetServer::get_id_handle` to explain its limitation and
point to `get_strong_handle`.
- Add a test for `get_strong_handle`
- Add a `duplicate_handles` field to `Assets` to avoid dropping assets
with a live handle generated by `get_strong_handle` (more reference
counting yay…)
- Fix typos in `Assets` docs

## Changelog
- Remove all redundant imports
- Fix cfg wasm32 targets

# Objective
The migration process for `bevy_color` (#12013) will be fairly involved:
there will be hundreds of affected files, and a large number of APIs.
## Solution
To allow us to proceed granularly, we're going to keep both
`bevy_color::Color` (new) and `bevy_render::Color` (old) around until
the migration is complete.
However, simply doing this directly is confusing! They're both called
`Color`, making it very hard to tell when a portion of the code has been
ported.
As discussed in #12056, by renaming the old `Color` type, we can make it
easier to gradually migrate over, one API at a time.

Fixes Skyboxes on WebGL, which broke in Bevy 0.13 due to the addition of

view and global uniforms.

In the provided shader, the type given for group 0 binding 3 has a size of 4. As the device does not support `DownlevelFlags::BUFFER_BINDINGS_NOT_16_BYTE_ALIGNED`, the type must have a size that is a multiple of 16 bytes.
```
It would be nice if this could be backported to a 0.13.1 patch as well
if possible. I'm needing to rely on my own fork for now.
## Solution
Similar to the Globals uniform solution here:
d31de3f139/crates/bevy_render/src/globals.rs (L59-L60)

# Objective
`Scope::spawn`, `Scope::spawn_on_external`, and `Scope::spawn_on_scope`
have different signatures depending on whether the `multi-threaded`
feature is enabled. The single-threaded version has a stricter signature
that prevents sending the `Scope` itself to spawned tasks.
## Solution
Changed the lifetime constraints in the single-threaded signatures from
`'env` to `'scope` to match the multi-threaded version.
This was split off from #11906.
# Objective
- Assist Bevy contributors in the creation of `bevy_color` spaces by

2024-02-19T14:59:34.896266Z ERROR bevy_render::render_resource::pipeline_cache: failed to create shader module: Validation Error
Caused by:
In Device::create_shader_module
Shader validation error:
Type [40] '' is invalid
Capability Capabilities(CUBE_ARRAY_TEXTURES) is required
```
## Solution
- Split up NO_ARRAY_TEXTURES_SUPPORT into both NO_ARRAY_TEXTURES_SUPPORT
and NO_CUBE_ARRAY_TEXTURES_SUPPORT and correctly apply
NO_ARRAY_TEXTURES_SUPPORT for iOS Simulator using the cfg flag
introduced in #10178.
---
## Changelog
### Fixed
- Rendering on iOS Simulator due to missing CUBE_ARRAY_TEXTURES support.

# Objective
- The `touch_screen_input_system` system runs on every tick.
- It unconditionally calls `update(&mut self)`, on the `Touches`
resource.
- This blocks the usage of a `resource_changed::<Touches>` run
condition.
## Solution
- Remove `update(&mut self)` as it's only used in this one system, and
in-lining the method implementation removes an indirection to an
ambiguously named method.
- Add conditional checks around the calls to clearing the internal maps.
