# Objective
- Be more explicit in the name of the module for the ui debug overlay
- Avoid confusion and possible overlap with new overlays
## Solution
- Rename `debug_overlay` to `ui_debug_overlay`
# Objective
CI is currently broken because of `DiagnosticsRecorder` not being Send
and Sync as required by Resource.
## Solution
Wrap `DiagnosticsRecorder` internally with a `WgpuWrapper`.
# Objective
- #10572
There is no 2D primitive available for the common shape of an annulus
(ring).
## Solution
This PR introduces a new type to the existing math primitives:
- `Annulus`: the region between two concentric circles
---
## Changelog
### Added
- `Annulus` primitive to the `bevy_math` crate
- `Annulus` tests (`diameter`, `thickness`, `area`, `perimeter` and
`closest_point` methods)

# Objective
I found that some .rs files are unnecessarily executable.
Rust source files may start with a shebang-like statement `#!`, so let's
make sure they are not executable just in case.
Here is the result of the `find` commend that lists executable .rs files
as of main branch `86bd648`.
```console
$ find -name \*.rs -type f -executable
./crates/bevy_gizmos/src/lib.rs
./crates/bevy_tasks/src/lib.rs
./crates/bevy_time/src/lib.rs
./crates/bevy_transform/src/lib.rs
./src/lib.rs
```
It appears that the permissions of those files were originally 644, but
were unexpectedly changed to 755 by commit
52e3f2007b.
## Solution
Make them not executable by using this command;
`find -name \*.rs -type f -executable -exec chmod --verbose a-x -- {}
\+`
# Objective
Fix the regression for Root Node's Layout behavior introduced in
https://github.com/bevyengine/bevy/pull/12268
- Add regression test for Root Node Layout's behaving as they did before
0.13.1
- Restore pre 0.13.1 Root Node Layout behavior (fixes
https://github.com/bevyengine/bevy/issues/12624)
## Solution
This implements [@nicoburns suggestion
](https://discord.com/channels/691052431525675048/743663673393938453/1221593626476548146),
where instead of adding the camera to the taffy node tree, we revert
back to adding a new "parent" node for each root node while maintaining
their relationship with the camera.
> If you can do the ecs change detection to move the node to the correct
Taffy instance for the camera then you should also be able to move it to
a `Vec` of root nodes for that camera.
---
## Changelog
Fixed https://github.com/bevyengine/bevy/issues/12624 - Restores pre
0.13.1 Root Node Layout behavior
## Migration Guide
If you were affected by the 0.13.1 regression and added `position_type:
Absolute` to all your root nodes you might be able to reclaim some LOC
by removing them now that the 0.13 behavior is restored.
# Objective
- Adds line styles to bevy gizmos, suggestion of #9400
- Currently solid and dotted lines are implemented but this can easily
be extended to support dashed lines as well if that is wanted.
## Solution
- Adds the enum `GizmoLineStyle` and uses it in each `GizmoConfig` to
configure the style of the line.
- Each "dot" in a dotted line has the same width and height as the
`line_width` of the corresponding line.
---
## Changelog
- Added `GizmoLineStyle` to `bevy_gizmos`
- Added a `line_style: GizmoLineStyle ` attribute to `GizmoConfig`
- Updated the `lines.wgsl` shader and the pipelines accordingly.
## Migration Guide
- Any manually created `GizmoConfig` must now include the `line_style`
attribute
## Additional information
Some pretty pictures :)
This is the 3d_gizmos example with/without `line_perspective`:

# Objective
This gets Bevy building on Wasm when the `atomics` flag is enabled. This
does not yet multithread Bevy itself, but it allows Bevy users to use a
crate like `wasm_thread` to spawn their own threads and manually
parallelize work. This is a first step towards resolving #4078 . Also
fixes#9304.
This provides a foothold so that Bevy contributors can begin to think
about multithreaded Wasm's constraints and Bevy can work towards changes
to get the engine itself multithreaded.
Some flags need to be set on the Rust compiler when compiling for Wasm
multithreading. Here's what my build script looks like, with the correct
flags set, to test out Bevy examples on web:
```bash
set -e
RUSTFLAGS='-C target-feature=+atomics,+bulk-memory,+mutable-globals' \
cargo build --example breakout --target wasm32-unknown-unknown -Z build-std=std,panic_abort --release
wasm-bindgen --out-name wasm_example \
--out-dir examples/wasm/target \
--target web target/wasm32-unknown-unknown/release/examples/breakout.wasm
devserver --header Cross-Origin-Opener-Policy='same-origin' --header Cross-Origin-Embedder-Policy='require-corp' --path examples/wasm
```
A few notes:
1. `cpal` crashes immediately when the `atomics` flag is set. That is
patched in https://github.com/RustAudio/cpal/pull/837, but not yet in
the latest crates.io release.
That can be temporarily worked around by patching Cpal like so:
```toml
[patch.crates-io]
cpal = { git = "https://github.com/RustAudio/cpal" }
```
2. When testing out `wasm_thread` you need to enable the `es_modules`
feature.
## Solution
The largest obstacle to compiling Bevy with `atomics` on web is that
`wgpu` types are _not_ Send and Sync. Longer term Bevy will need an
approach to handle that, but in the near term Bevy is already configured
to be single-threaded on web.
Therefor it is enough to wrap `wgpu` types in a
`send_wrapper::SendWrapper` that _is_ Send / Sync, but panics if
accessed off the `wgpu` thread.
---
## Changelog
- `wgpu` types that are not `Send` are wrapped in
`send_wrapper::SendWrapper` on Wasm + 'atomics'
- CommandBuffers are not generated in parallel on Wasm + 'atomics'
## Questions
- Bevy should probably add CI checks to make sure this doesn't regress.
Should that go in this PR or a separate PR? **Edit:** Added checks to
build Wasm with atomics

# Objective
Currently the built docs only shows the logo and favicon for the top
level `bevy` crate. This makes views like
https://docs.rs/bevy_ecs/latest/bevy_ecs/ look potentially unrelated to
the project at first glance.
## Solution
Reproduce the docs attributes for every crate that Bevy publishes.
Ideally this would be done with some workspace level Cargo.toml control,
but AFAICT, such support does not exist.
# Objective
Make it easy to get the ids of all the components in a bundle (and
initialise any components not yet initialised). This is fairly similar
to the `Bundle::get_component_ids()` method added in the observers PR
however that will return none for any non-initialised components. This
is exactly the API space covered by `Bundle::component_ids()` however
that isn't possible to call outside of `bevy_ecs` as it requires `&mut
Components` and `&mut Storages`.
## Solution
Added `World.init_bundle<B: Bundle>()` which similarly to
`init_component` and `init_resource`, initialises all components in the
bundle and returns a vector of their component ids.
---
## Changelog
Added the method `init_bundle` to `World` as a counterpart to
`init_component` and `init_resource`.

# Objective
get_asset_paths tries to check whether a folder is empty, and if so
delete it. However rather than checking whether any subfolder contains
files it checks whether _all_ subfolders have files.
Also cleanup various BoxedFutures in async recursive functions like
these, rust 1.77 now allows recursive async functions (albeit still by
boxing), hurray! This is a followup to #12550 (sorta). More BoxedFuture
stuff can be removed now that rust 1.77 is out, which can use async
recursive functions! This is mainly just cleaner code wise - the
recursion still boxes the future so not much to win there.
PR is mainly whitespace changes so do disable whitespace diffs for
easier review.
# Objective
Follow up from PR #12369 to extract lighting structs from light/mod.rs
into their own file.
Part of the Purdue Refactoring Team's goals issue #12349
## Solution
- Moved PointLight from light/mod.rs to light/point_light.rs
- Moved SpotLight from light/mod.rs to light/spot_light.rs
- Moved DirectionalLight from light/mod.rs to light/directional_light.rs
# Objective
Remove color specialization from `SpritePipeline` after it became
useless in #9597
## Solution
Removed the `COLORED` flag from the pipeline key and removed the
specializing the pipeline over it.
---
## Changelog
### Removed
- `SpritePipelineKey` no longer contains the `COLORED` flag. The flag
has had no effect on how the pipeline operates for a while.
## Migration Guide
- The raw values for the `HDR`, `TONEMAP_IN_SHADER` and `DEBAND_DITHER`
flags have changed, so if you were constructing the pipeline key from
raw `u32`s you'll have to account for that.
# Objective
I was reading some of the Archetype and Bundle code and was getting
confused a little bit in some places (is the `archetype_id` in
`AddBundle` the source or the target archetype id?).
Small PR that adds some docstrings to make it easier for first-time
readers.
# Objective
* Adopted #12025 to fix merge conflicts
* In some cases we used manual impls for certain types, though they are
(at least, now) unnecessary.
## Solution
* Use macros and reflecting-by-value to avoid this clutter.
* Though there were linker issues with Reflect and the CowArc in
AssetPath (see https://github.com/bevyengine/bevy/issues/9747), I
checked these are resolved by using #[reflect_value].

# Objective
- Clarify that `ButtonInput::just_release` and
`ButtonInput::just_pressed` don't imply information about the state of
`ButtonInput::pressed` or their counterparts.
Fixes#12600
## Solution
Removed Into<AssetId<T>> for Handle<T> as proposed in Issue
conversation, fixed dependent code
## Migration guide
If you use passing Handle by value as AssetId, you should pass reference
or call .id() method on it
Before (0.13):
`assets.insert(handle, value);`
After (0.14):
`assets.insert(&handle, value);`
or
`assets.insert(handle.id(), value);`
# Objective
Fixes issue #12613 - the RNG used in examples is _deterministic_, but
its implementation is not _portable_ across platforms. We want to switch
to using a portable RNG that does not vary across platforms, to ensure
certain examples play out the same way every time.
## Solution
Replace all occurences of `rand::rngs::StdRng` with
`rand_chacha::ChaCha8Rng`, as recommended in issue #12613
---
## Changelog
- Add `rand_chacha` as a new dependency (controversial?)
- Replace all occurences of `rand::rngs::StdRng` with
`rand_chacha::ChaCha8Rng`
# Objective
- Implements maths and `Animatable` for `Srgba` as suggested
[here](https://github.com/bevyengine/bevy/issues/12617#issuecomment-2013494774).
## Solution
- Implements `Animatable` and maths for `Srgba` just like their
implemented for other colors.
---
## Changelog
- Updated the example to mention `Srgba`.
## Migration Guide
- The previously existing implementation of mul/div for `Srgba` did not
modify `alpha` but these operations do modify `alpha` now. Users need to
be aware of this change.
# Objective
- Allow registering of systems from Commands with
`Commands::register_one_shot_system`
- Make registering of one shot systems more easy
## Solution
- Add the Command `RegisterSystem` for Commands use.
- Creation of SystemId based on lazy insertion of the System
- Changed the privacy of the fields in SystemId so Commands can return
the SystemId
---
## Changelog
### Added
- Added command `RegisterSystem`
- Added function `Commands::register_one_shot_system`
- Added function `App::register_one_shot_system`
### Changed
- Changed the privacy and the type of struct tuple to regular struct of
SystemId
## Migration Guide
- Changed SystemId fields from tuple struct to a normal struct
If you want to access the entity field, you should use
`SystemId::entity` instead of `SystemId::0`
## Showcase
> Before, if you wanted to register a system with `Commands`, you would
need to do:
```rust
commands.add(|world: &mut World| {
let id = world.register_system(your_system);
// You would need to insert the SystemId inside an entity or similar
})
```
> Now, you can:
```rust
let id = commands.register_one_shot_system(your_system);
// Do what you want with the Id
```

# Objective
- Fixes#12570
## Solution
Previously, cardinal splines constructed by `CubicCardinalSpline` would
leave out their endpoints when constructing the cubic curve segments
connecting their points. (See the linked issue for details.)
Now, cardinal splines include the endpoints. For instance, the provided
usage example
```rust
let points = [
vec2(-1.0, -20.0),
vec2(3.0, 2.0),
vec2(5.0, 3.0),
vec2(9.0, 8.0),
];
let cardinal = CubicCardinalSpline::new(0.3, points).to_curve();
let positions: Vec<_> = cardinal.iter_positions(100).collect();
```
will actually produce a spline that connects all four of these points
instead of just the middle two "interior" points.
Internally, this is achieved by duplicating the endpoints of the vector
of control points before performing the construction of the associated
`CubicCurve`. This amounts to specifying that the tangents at the
endpoints `P_0` and `P_n` (say) should be parallel to `P_1 - P_0` and
`P_n - P_{n-1}`.
---
## Migration Guide
Any users relying on the old behavior of `CubicCardinalSpline` will have
to truncate any parametrizations they used in order to access a curve
identical to the one they had previously. This would be done by chopping
off a unit-distance segment from each end of the parametrizing interval.
For instance, if a user's existing code looks as follows
```rust
fn interpolate(t: f32) -> Vec2 {
let points = [
vec2(-1.0, -20.0),
vec2(3.0, 2.0),
vec2(5.0, 3.0),
vec2(9.0, 8.0),
];
let my_curve = CubicCardinalSpline::new(0.3, points).to_curve();
my_curve.position(t)
}
```
then in order to obtain similar behavior, `t` will need to be shifted up
by 1, since the output of `CubicCardinalSpline::to_curve` has introduced
a new segment in the interval [0,1], displacing the old segment from
[0,1] to [1,2]:
```rust
fn interpolate(t: f32) -> Vec2 {
let points = [
vec2(-1.0, -20.0),
vec2(3.0, 2.0),
vec2(5.0, 3.0),
vec2(9.0, 8.0),
];
let my_curve = CubicCardinalSpline::new(0.3, points).to_curve();
my_curve.position(t+1)
}
```
(Note that this does not provide identical output for values of `t`
outside of the interval [0,1].)
On the other hand, any user who was specifying additional endpoint
tangents simply to get the curve to pass through the right points (i.e.
not requiring exactly the same output) can simply omit the endpoints
that were being supplied only for control purposes.
---
## Discussion
### Design considerations
This is one of the two approaches outlined in #12570 — in this PR, we
are basically declaring that the docs are right and the implementation
was flawed.
One semi-interesting question is how the endpoint tangents actually
ought to be defined when we include them, and another option considered
was mirroring the control points adjacent to the endpoints instead of
duplicating them, which would have had the advantage that the expected
length of the corresponding difference should be more similar to that of
the other difference-tangents, provided that the points are equally
spaced.
In this PR, the duplication method (which produces smaller tangents) was
chosen for a couple reasons:
- It seems to be more standard
- It is exceptionally simple to implement
- I was a little concerned that the aforementioned alternative would
result in some over-extrapolation
### An annoyance
If you look at the code, you'll see I was unable to find a satisfactory
way of doing this without allocating a new vector. This doesn't seem
like a big problem given the context, but it does bother me. In
particular, if there is some easy parallel to `slice::windows` for
iterators that doesn't pull in an external dependency, I would love to
know about it.
# Objective
- A new example `rounded_borders` was introduced in #12500, similar to

# Objective
Lets say I have the following `.meta` file:
```RON
(
meta_format_version: "1.0",
asset: Ignore,
)
```
When a file is inside the `assets` directory and processing is enabled,
the processor will copy the file into `imported_assets` although it
should be ignored and therefore not copied.
## Solution
- I added a simple check that does not copy the assets if the
AssetAction is `Ignore`.
## Migration Guide
- The public `ProcessResult` enum now has a `ProcessResult::Ignore`
variant that must be handled.
# Objective
Fix Pr CI failing over dead code in tests and main branch CI failing

- #12500 use the primary window resolution to do all its calculation.
This means bad support for multiple windows or multiple ui camera
## Solution
- Use camera driven UI (https://github.com/bevyengine/bevy/pull/10559)
# Objective
- since #12500, text is a little bit more gray in UI
## Solution
- don't multiply color by alpha. I think this was done in the original
PR (#8973) for shadows which were not added in #12500
