# Objective
Fixes#10106
Adds a table showing computational complexity, as seen for Query (and
similar to std::collections docs).
## Solution
Add the complexity table

# 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
- Improve example from #12299
- Make it frame rate independent
- Make it not randomly random
## Solution
- Transitions between transforms will take 2 seconds instead of 100
frames
- Random is seeded
# 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.

## Solution
- Updated the link

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
- We must have googly eyes.
- Also it would be nice if there was an example of a desk toy
application (like the old NEKO.EXE).
## Solution
- Created an example with googly eyed Bevy logo under
examples/games/desktoy.rs.
---
## Changelog
- Added "Desk Toy" game example showcasing window transparency and hit
test.

# 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
- Make it easier to figure out how to add asset sources
## Solution
- Add an example that adds an asset source, it functions almost
identical to the embedded_asset example
- Move the file from the embedded_asset example into a `files/` folder
# 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#12226
Prior to the `bevy_color` port, `DARK GRAY` used to mean "dark grey."
But it is now lighter than `GRAY`, matching the css4 spec.
## Solution
Change usages of `css::DARK_GRAY` to `Color::srgb(0.25, 0.25, 0.25)` to
restore the examples to their former colors.
With one exception: `display_and_visibility`. I think the new color is
an improvement.
## Note
A lot of these examples could use nicer colors. I'm not trying to revamp
everything here.
The css4 palette is truly a horror. See #12176 and #12080 for some
discussion about alternatives.
# 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
users

# 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
- After https://github.com/bevyengine/bevy/pull/11165, example `ui` is
not pretty as it displays the Bevy logo on a white background, with a
comment that is now wrong
## Solution
- Remove the background color
# Objective
- Make running CI locally relatively less painful by allowing
continuation after failure
- Fix#12206
## Solution
Previously, `ci` would halt after encounting a failure (or shortly
thereafter). For instance, if you ran `cargo run -p ci` and a single
test within a CI check failed somewhere in the middle, you would never
even reach many of the other tests within the check and certainly none
of the CI checks that came afterward. This was annoying; if I am fixing
issues with CI tests, I want to just see all of the issues up-front
instead of having to rerun CI every time I fix something to see the next
error.
Furthermore, it is not infrequent (because of subtle
configuration/system differences) to encounter spurious CI failures
locally; previously, when these occurred, they would make the process of
running CI largely pointless, since you would have to push your branch
in order to see your actual CI failures from the automated testing
service.
Now, when running `ci` locally, we have a couple new tools to ameliorate
these and provide a smoother experience:
- Firstly, there is a new optional flag `--keep-going` that can be
passed while calling `ci` (e.g. `cargo run -p ci -- doc --keep-going`).
It has the following effects:
- It causes the `--keep-going` flag to be passed to the script's `cargo
doc` and `cargo check` invocations, so that they do not stop when they
encounter an error in a single module; instead, they keep going (!) and
find errors subsequently.
- It causes the `--no-fail-fast` flag to be passed to the script's
`cargo test` invocations, to similar effect.
- Finally, it causes `ci` itself not to abort after a single check
fails; instead, it will run every check that was invoked.
Thus, for instance, `cargo run -p ci -- --keep-going` will run every CI
check even if it encounters intermediate failures, and every such check
will itself be run to completion.
- Secondly, we now allow multiple ordinary arguments to be passed to
`ci`. For instance, `cargo -p ci -- doc test` now executes both the
'doc' checks and the 'test' checks. This allows the caller to run the
tests they care about with fewer invocations of `ci`.
As of this PR, automated testing will remain unchanged.
---
## Changelog
- tools/ci/src/main.rs refactored into staging and execution steps,
since the previous control flow did not naturally support continuing
after failure.
- Added "--keep-going" flag to `ci`.
- Added support for invoking `ci` with multiple arguments.
---
## Discussion
### Design considerations
I had originally split this into separate flags that controlled:
1. whether `--keep-going`/`--no-fail-fast` would be passed to the
constituent commands
2. whether `ci` would continue after a component test failed
However, I decided to merge these two behaviors, since I think that, if
you're in the business of seeing all the errors, you'll probably want to
actually see all of the errors. One slightly annoying thing, however,
about the new behavior with `--keep-going`, is that you will sometimes
find yourself wishing that the script would pause or something, since it
tends to fill the screen with a lot of junk. I have found that sending
stdout to /dev/null helps quite a bit, but I don't think `cargo fmt` or
`cargo clippy` actually write to stderr, so you need to be cognizant of
that (and perhaps invoke the lints separately).
~~Next, I'll mention that I feel somewhat strongly that the current
behavior of `ci` for automated testing should remain the same, since its
job is more like detecting that errors exist rather than finding all of
them.~~ (I was convinced this could have value.) Orthogonally, there is
the question of whether or not we might want to make this (or something
similar) actually the default behavior and make the automated test
script invoke some optional flags — it doesn't have to type with its
hands, after all. I'm not against that, but I don't really want to rock
the boat much more with this PR, since anyone who looks at the diff
might already be a little incensed.
# 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
- Follow-up to #12211
- Introduces an example project that demonstrates the implementation and
behavior of `Gizmos::axes` for an entity with a `Transform` component.
## Solution
In order to demonstrate how `Gizmo::axes` can be used and behaves in
practice, we introduce an example of a simple scene containing a pair of
cuboids locked in a grotesque, inscrutable dance: the two are repeatedly
given random `Transform`s which they interpolate to, showing how the
axes move with objects as they translate, rotate, and scale.

On the implementation side, we demonstrate how to draw axes for
entities, automatically sizing them according to their bounding boxes
(so that the axes will be visible):
````rust
fn draw_axes(mut gizmos: Gizmos, query: Query<(&Transform, &Aabb), With<ShowAxes>>) {
for (&transform, &aabb) in &query {
let length = aabb.half_extents.length();
gizmos.axes(transform, length);
}
}
````
---
## Changelog
- Created examples/gizmos/axes.rs.
- Added 'axes' example to Cargo.toml.
