# Objective
- Fixes#11453
This is a temporary fix. There is PR fixing it (#11460), but I'm not
sure if it's going to be merged before the 0.13 release.
# Objective
- Implement an arc3d API for gizmos
- Solves #11536
## Solution
### `arc_3d`
- The current `arc3d` method on gizmos only takes an angle
- It draws an "standard arc" by default, this is an arc starting at
`Vec3::X`, in the XZ plane, in counter clockwise direction with a normal
that is facing up
- The "standard arc" can be customized with the usual gizmo builder
pattern. This way you'll be able to draw arbitrary arcs
### `short/long_arc_3d_between`
- Given `center`, `from`, `to` draws an arc between `from` and `to`
---
## Changelog
> This section is optional. If this was a trivial fix, or has no
externally-visible impact, you can delete this section.
- Added: `Gizmos::arc3d(&mut self, angle)` method
- Added: `Gizmos::long_arc_3d_between(&mut self, center, from, to)`
method
- Added: `Gizmos::short_arc_3d_between(&mut self, center, from, to)`
method

This PR factors out an orthogonal part of another PR as mentioned in
[this
comment](https://github.com/bevyengine/bevy/pull/11072#issuecomment-1883859573)
# Objective
Fixes#11311
## Solution
Adds an example to the documentation for `par_iter_mut`. I didn't add
any examples to `par_iter`, because I couldn't think of a good example
and I figure users can infer that `par_iter` and `par_iter_mut` are
similar.
# Objective
It's sometimes desirable to get a `Res<T>` rather than `&T` from
`World::get_resource`.
Alternative to #9940, partly adresses #9926
## Solution
added additional methods to `World` and `UnsafeWorldCell` to retrieve a
resource wrapped in a `Res`.
- `UnsafeWorldCell::get_resource_ref`
- `World::get_resource_ref`
- `World::resource_ref`
I can change it so `World::resource_mut` returns `ResMut` instead of
`Mut` as well if that's desired, but that could also be added later in a
seperate pr.

- Resolves#11377
## Solution
- Add marker component `IsDefaultUiCamera` that will be choosen first as
the default camera.
If you want the IsDefaultUiCamera default camera to be in another
window, thats now possible.
- `IsDefaultUiCamera` is expected to be within a single Camera, if that
assertion fails, one PrimaryWindow Camera will be choosen.

# Objective
Allow TextureAtlasBuilder in AssetLoader.
Fixes#2987
## Solution
- TextureAtlasBuilder no longer hold just AssetIds that are used to
retrieve the actual image data in `finish`, but &Image instead.
- TextureAtlasBuilder now required AssetId only optionally (and it is
only used to retrieve the index from the AssetId in TextureAtlasLayout),
## Issues
- The issue mentioned here
https://github.com/bevyengine/bevy/pull/11474#issuecomment-1904676937
now also extends to the actual atlas texture. In short: Calling
add_texture multiple times for the same texture will lead to duplicate
image data in the atlas texture and additional indices.
If you provide an AssetId we can probably do something to de-duplicate
the entries while keeping insertion order (suggestions welcome on how
exactly). But if you don't then we are out of luck (unless we can and
want to hash the image, which I do not think we want).
---
## Changelog
### Changed
- TextureAtlasBuilder `add_texture` can be called without providing an
AssetId
- TextureAtlasBuilder `finish` no longer takes Assets<Image> and no
longer returns a Handle<Image>
## Migration Guide
- For `add_texture` you need to wrap your AssetId in Some
- `finish` now returns the atlas texture image directly instead of a
handle. Provide the atlas texture to `add` on Assets<Texture> to get a
Handle<Image>
# Objective
allow automatic fixing of bad joint weights.
fix#10447
## Solution
- remove automatic normalization of vertexes with all zero joint
weights.
- add `Mesh::normalize_joint_weights` which fixes zero joint weights,
and also ensures that all weights sum to 1. this is a manual call as it
may be slow to apply to large skinned meshes, and is unnecessary if you
have control over the source assets.
note: this became a more significant problem with 0.12, as weights that
are close to, but not exactly 1 now seem to use `Vec3::ZERO` for the
unspecified weight, where previously they used the entity translation.
# Objective
Alternative to #11515.
Fixes change detection being triggered on the "image viewer image
material" every frame.
## Solution
- Split the megasystem into two separate systems: one to handle drop
events, and one to handle asset change events.
- Move the event reader iteration "outside." so that we're only doing
stuff when there are events.
- Flatten some of the more extreme nesting
- Other bits of cleanup, removing an unnecessary clone and unused
variable.
I think these systems can even run in parallel now, not that it
particularly matters.
# Objective
DXC+DX12 debug builds with an environment map have been broken since
https://github.com/bevyengine/bevy/pull/11366 merged due to an internal
compiler error in DXC. I tracked it down to a single `break` statement
and reported it upstream
(https://github.com/microsoft/DirectXShaderCompiler/issues/6183)
## Solution
Workaround the ICE by setting the for loop index variable to the max
value of the loop to avoid the `break` that's causing the ICE.
This works because it's the last thing in the for loop.
The `reflection_probes` and `pbr` examples both appear to still work
correctly.
# Objective
After #10520, I was experiencing seriously degraded performance that
ended up being due to never-drained `AssetEvent` events causing havoc
inside `extract_render_asset::<A>`. The same events being read over and
over again meant the same assets were being prepared every frame for
eternity. For what it's worth, I was noticing this on a static scene
about every 3rd or so time running my project.
* References #10520
* Fixes#11240
Why these events aren't sometimes drained between frames is beyond me
and perhaps worthy of another investigation, but the approach in this PR
effectively restores the original cached `EventReader` behavior (which
fixes it).
## Solution
I followed the [`CachedSystemState`
example](3a666cab23/crates/bevy_ecs/src/system/function_system.rs (L155))
to make sure that the `EventReader` state is cached between frames like
it used to be when it was an argument of `extract_render_asset::<A>`.
# Objective
Plugins are an incredible tool for encapsulating functionality. They are
low-key one of Bevy's best features. Combined with rust's module and
privacy system, it's a match made in heaven.
The one downside is that they can be a little too verbose to define. 90%
of all plugin definitions look something like this:
```rust
pub struct MyPlugin;
impl Plugin for MyPlugin {
fn build(&self, app: &mut App) {
app.init_resource::<CameraAssets>()
.add_event::<SetCamera>()
.add_systems(Update, (collect_set_camera_events, drive_camera).chain());
}
}
```
Every so often it gets a little spicier:
```rust
pub struct MyGenericPlugin<T>(PhantomData<T>);
impl<T> Default for MyGenericPlugin<T> {
fn default() -> Self { ... }
}
impl<T> Plugin for MyGenericPlugin<T> { ... }
```
This is an annoying amount of boilerplate. Ideally, plugins should be
focused and small in scope, which means any app is going to have a *lot*
of them. Writing a plugin should be as easy as possible, and the *only*
part of this process that carries any meaning is the body of `fn build`.
## Solution
Implement `Plugin` for functions that take `&mut App` as a parameter.
The two examples above now look like this:
```rust
pub fn my_plugin(app: &mut App) {
app.init_resource::<CameraAssets>()
.add_event::<SetCamera>()
.add_systems(Update, (collect_set_camera_events, drive_camera).chain());
}
pub fn my_generic_plugin<T>(app: &mut App) {
// No need for PhantomData, it just works.
}
```
Almost all plugins can be written this way, which I believe will make
bevy code much more attractive. Less boilerplate and less meaningless
indentation. More plugins with smaller scopes.
---
## Changelog
The `Plugin` trait is now implemented for all functions that take `&mut
App` as their only parameter. This is an abbreviated way of defining
plugins with less boilerplate than manually implementing the trait.

# Objective
Fixes#11533
When `AssetPath`s are created from a string type, they are parsed into
an `AssetSource`, a `Path`, and a `Label`.
The current method of parsing has some unnecessary quirks:
- The presence of a `:` character is assumed to be the start of an asset
source indicator.
- This is not necessarily true. There are valid uses of a `:` character
in an asset path, for example an http source's port such as
`localhost:80`.
- If there are multiple instances of `://`, the last one is assumed to
be the asset source deliminator.
- This has some unexpected behavior. Even in a fully formed path, such
as `http://localhost:80`, the `:` between `localhost` and `80` is
assumed to be the start of an asset source, causing an error since it
does not form the full sequence `://`.
## Solution
Changes the `AssetPath`'s `parse_internal` method to be more permissive.
- Only the exact sequence `://` is taken to be the asset source
deliminator, and only the first one if there are multiple.
- As a consequence, it is no longer possible to detect a malformed asset
source deliminator, and so the corresponding error was removed.
# Objective
https://github.com/bevyengine/bevy/pull/5103 caused a bug where
`Sprite::rect` was ignored by the engine. (Did nothing)
## Solution
My solution changes the way how Bevy calculates the rect, based on this
table:
| `atlas_rect` | `Sprite::rect` | Result |
|--------------|----------------|------------------------------------------------------|
| `None` | `None` | `None` |
| `None` | `Some` | `Sprite::rect` |
| `Some` | `None` | `atlas_rect` |
| `Some` | `Some` | `Sprite::rect` is used, relative to `atlas_rect.min`
|
# Objective
One of a few Bevy Asset improvements I would like to make: #11216.
Currently asset processing and asset saving are handled by the same
trait, `AssetSaver`. This makes it difficult to reuse saving
implementations and impossible to have a single "universal" saver for a
given asset type.
## Solution
This PR splits off the processing portion of `AssetSaver` into
`AssetTransformer`, which is responsible for transforming assets. This
change involves adding the `LoadTransformAndSave` processor, which
utilizes the new API. The `LoadAndSave` still exists since it remains
useful in situations where no "transformation" of the asset is done,
such as when compressing assets.
## Notes:
As an aside, Bikeshedding is welcome on the names. I'm not entirely
convinced by `AssetTransformer`, which was chosen mostly because
`AssetProcessor` is taken. Additionally, `LoadTransformSave` may be
sufficient instead of `LoadTransformAndSave`.
---
## Changelog
### Added
- `AssetTransformer` which is responsible for transforming Assets.
- `LoadTransformAndSave`, a `Process` implementation.
### Changed
- Changed `AssetSaver`'s responsibilities from processing and saving to
just saving.
- Updated `asset_processing` example to use new API.
- Old asset .meta files regenerated with new processor.
# Objective
Keep core dependencies up to date.
## Solution
Update the dependencies.
wgpu 0.19 only supports raw-window-handle (rwh) 0.6, so bumping that was
included in this.
The rwh 0.6 version bump is just the simplest way of doing it. There
might be a way we can take advantage of wgpu's new safe surface creation
api, but I'm not familiar enough with bevy's window management to
untangle it and my attempt ended up being a mess of lifetimes and rustc
complaining about missing trait impls (that were implemented). Thanks to
@MiniaczQ for the (much simpler) rwh 0.6 version bump code.
Unblocks https://github.com/bevyengine/bevy/pull/9172 and
https://github.com/bevyengine/bevy/pull/10812
~~This might be blocked on cpal and oboe updating their ndk versions to
0.8, as they both currently target ndk 0.7 which uses rwh 0.5.2~~ Tested
on android, and everything seems to work correctly (audio properly stops
when minimized, and plays when re-focusing the app).
---
## Changelog
- `wgpu` has been updated to 0.19! The long awaited arcanization has
been merged (for more info, see
https://gfx-rs.github.io/2023/11/24/arcanization.html), and Vulkan
should now be working again on Intel GPUs.
- Targeting WebGPU now requires that you add the new `webgpu` feature
(setting the `RUSTFLAGS` environment variable to
`--cfg=web_sys_unstable_apis` is still required). This feature currently
overrides the `webgl2` feature if you have both enabled (the `webgl2`
feature is enabled by default), so it is not recommended to add it as a
default feature to libraries without putting it behind a flag that
allows library users to opt out of it! In the future we plan on
supporting wasm binaries that can target both webgl2 and webgpu now that
wgpu added support for doing so (see
https://github.com/bevyengine/bevy/issues/11505).
- `raw-window-handle` has been updated to version 0.6.
## Migration Guide
- `bevy_render::instance_index::get_instance_index()` has been removed
as the webgl2 workaround is no longer required as it was fixed upstream
in wgpu. The `BASE_INSTANCE_WORKAROUND` shaderdef has also been removed.
- WebGPU now requires the new `webgpu` feature to be enabled. The
`webgpu` feature currently overrides the `webgl2` feature so you no
longer need to disable all default features and re-add them all when
targeting `webgpu`, but binaries built with both the `webgpu` and
`webgl2` features will only target the webgpu backend, and will only
work on browsers that support WebGPU.
- Places where you conditionally compiled things for webgl2 need to be
updated because of this change, eg:
- `#[cfg(any(not(feature = "webgl"), not(target_arch = "wasm32")))]`
becomes `#[cfg(any(not(feature = "webgl") ,not(target_arch = "wasm32"),
feature = "webgpu"))]`
- `#[cfg(all(feature = "webgl", target_arch = "wasm32"))]` becomes
`#[cfg(all(feature = "webgl", target_arch = "wasm32", not(feature =
"webgpu")))]`
- `if cfg!(all(feature = "webgl", target_arch = "wasm32"))` becomes `if
cfg!(all(feature = "webgl", target_arch = "wasm32", not(feature =
"webgpu")))`
- `create_texture_with_data` now also takes a `TextureDataOrder`. You
can probably just set this to `TextureDataOrder::default()`
- `TextureFormat`'s `block_size` has been renamed to `block_copy_size`
- See the `wgpu` changelog for anything I might've missed:

# Objective
Make APIs more consistent and ergonomic by adding a `new` constructor
for `Circle` and `Sphere`.
This could be seen as a redundant "trivial constructor", but in
practise, it seems valuable to me. I have lots of cases where formatting
becomes ugly because of the lack of a constructor, like this:
```rust
Circle {
radius: self.radius(),
}
.contains_local_point(centered_pt)
```
With `new`, it'd be formatted much nicer:
```rust
Circle::new(self.radius()).contains_local_point(centered_pt)
```
Of course, this is just one example, but my circle/sphere definitions
very frequently span three or more lines when they could fit on one.
Adding `new` also increases consistency. `Ellipse` has `new` already,
and so does the mesh version of `Circle`.
## Solution
Add a `new` constructor for `Circle` and `Sphere`.
# Objective
- Fix documentation for `AssetReader::is_directory` (it is currently
exactly the same as docs for `read_directory`)
---------

# Objective
- Fixes#11516
## Solution
- Add Animated Material example (colors are hue-cycling smoothly
per-mesh)
Note: this example reproduces the perf issue found in #10610 pretty
consistently, with and without the changes from that PR included. Frame
time is sometimes around 4.3ms, other times around 12-14ms. Its pretty
random per run. I think this clears #10610 for merge.
# Objective
- Some passes recreate a sampler when creating a bind group to be
cached, even if the sampler is always the same.
## Solution
- Store the sampler in the corresponding pipeline resource.
# Objective
While working on #11527 I spotted that the internal field for the label
of a `Schedule` is called `name`. Using `label` seems more in line with
the other naming across Bevy.
## Solution
Renaming the field was straightforward since it's not exposed outside of
the module. This also means a changelog or migration guide isn't
necessary.
# Objective
Theres no explaination for what the compiler flags
`config_fast_builds.toml` do
## Solution
Explain what the flags in `config_fast_builds.toml` do.
# Objective
Fixes#11411
## Solution
- Added a simple example how to create and configure custom schedules
that are run by the `Main` schedule.
- Spot checked some of the API docs used, fixed `App::add_schedule` docs
that referred to a function argument that was removed by #9600.
## Open Questions
- While spot checking the docs, I noticed that the `Schedule` label is
stored in a field called `name` instead of `label`. This seems
unintuitive since the term label is used everywhere else. Should we
change that field name? It was introduced in #9600. If so, I do think
this change would be out of scope for this PR that mainly adds the
example.
# Objective
Rust analyzer kept complaining about a cyclic dependency due to
`bevy_input` having a dev-dependency on `bevy`.
`bevy_input` was also missing `bevy_reflect`'s "smol_str" feature which
it needs to compile on its own.
Fixes#10256
## Solution
Remove the dev-dependency on `bevy` from `bevy_input` since it was only
used to reduce imports for 1 test and 3 doc examples by 1 line each, as
`bevy_input` already has dependencies on everything needed for those
tests and doctests to work.
Add `bevy_reflect`'s "smol_str" feature to `bevy_input`'s dependency
list as it needs it to actually compile.
# Objective
Fixes#10414.
That issue and its comments do a great job of laying out the case for
this.
## Solution
Added an optional `spatial_scale` field to `PlaybackSettings`, which
overrides the default value set on `AudioPlugin`.
## Changelog
- `AudioPlugin::spatial_scale` has been renamed to
`default_spatial_scale`.
- `SpatialScale` is no longer a resource and is wrapped by
`DefaultSpatialScale`.
- Added an optional `spatial_scale` to `PlaybackSettings`.
## Migration Guide
`AudioPlugin::spatial_scale` has been renamed to `default_spatial_scale`
and the default spatial scale can now be overridden on individual audio
sources with `PlaybackSettings::spatial_scale`.
If you were modifying or reading `SpatialScale` at run time, use
`DefaultSpatialScale` instead.
```rust
// before
app.add_plugins(DefaultPlugins.set(AudioPlugin {
spatial_scale: SpatialScale::new(AUDIO_SCALE),
..default()
}));
// after
app.add_plugins(DefaultPlugins.set(AudioPlugin {
default_spatial_scale: SpatialScale::new(AUDIO_SCALE),
..default()
}));
```
# Objective
TypeUuid is deprecated, remove it.

# Objective
Since #10339, the contrast in this example has been very low. While I
was in there, I made a few other tweaks to the style.
Alternative to #10102.
## Solution
- Increase brightness of inactive buttons for higher contrast on the new
clear color
- Combine `DEAD_COLOR` and `EXTENT_COLOR`. These were using the same
value, and combining them might make the intent a little clearer. (This
is the single color for "not the live zone.")
- Make the "stick buttons" slightly smaller, so it's a bit more obvious
that they are sitting inside of the default dead zone.
- Remove explicit text color -- it was the same as the default
- Add top-left margin to the text in the top left, and change the font
size to better match other examples with text in the corner.

"mutably" but instead said "immutably."
- Fixes#11430.
## Solution
- Replace "immutably" with "mutably."
# Objective
- Using the latest nightly for `miri` is generally desirable as we want
to catch regressions upstream or new problems quickly
- https://github.com/rust-lang/rust/pull/120123 should be merged now, so
it should work.
## Solution
- Revert #11421.

#10946 added bounding volume types and an `IntersectsVolume` trait, but
didn't actually implement intersections between bounding volumes.
This PR implements AABB-AABB, circle-circle / sphere-sphere, and
AABB-circle / AABB-sphere intersections.
## Solution
Implement `IntersectsVolume` for bounding volume pairs. I also added
`closest_point` methods to return the closest point on the surface /
inside of bounding volumes. This is used for AABB-circle / AABB-sphere
intersections.

# Objective
TextureAtlases are commonly used to drive animations described as a
consecutive range of indices. The current TextureAtlasBuilder uses the
AssetId of the image to determine the index of the texture in the
TextureAtlas. The AssetId of an Image Asset can change between runs.
The TextureAtlas exposes
[`get_texture_index`](https://docs.rs/bevy/latest/bevy/sprite/struct.TextureAtlas.html#method.get_texture_index)
to get the index from a given AssetId, but this needlessly complicates
the process of creating a simple TextureAtlas animation.
Fixes#2459
## Solution
- Use the (ordered) image_ids of the 'texture to place' vector to
retrieve the packed locations and compose the textures of the
TextureAtlas.
# Objective
- Fix a memory leak in the dynamic ECS example mentioned in #11459
## Solution
- Rather than allocate the memory manually instead store a collection of
`Vec` that will be dropped after it is used.

I must have misinterpreted `OwningPtr`s semantics when initially writing
this example. I believe we should be able to provide better APIs here
for inserting dynamic components that don't require the user to wrangle
so much unsafety. We have no other examples using `insert_by_ids` and
our only tests show it being used for 1 or 2 values with nested calls to
`OwningPtr::make` despite the function taking an iterator. Rust's type
system is quite restrictive here but we could at least let
`OwningPtr::new` take non u8 `NonNull`.
I also agree with #11459 that we should generally be trying to simplify
and clarify this example.
# Objective
It would be convenient to be able to call functions with `Commands` as a
parameter without having to move your own instance of `Commands`. Since
this struct is composed entirely of references, we can easily get an
owned instance of `Commands` by shortening the lifetime.
## Solution
Add `Commands::reborrow`, `EntiyCommands::reborrow`, and
`Deferred::reborrow`, which returns an owned version of themselves with
a shorter lifetime.
Remove unnecessary lifetimes from `EntityCommands`. The `'w` and `'s`
lifetimes only have to be separate for `Commands` because it's used as a
`SystemParam` -- this is not the case for `EntityCommands`.
---
## Changelog
Added `Commands::reborrow`. This is useful if you have `&mut Commands`
but need `Commands`. Also added `EntityCommands::reborrow` and
`Deferred:reborrow` which serve the same purpose.
## Migration Guide
The lifetimes for `EntityCommands` have been simplified.
```rust
// Before (Bevy 0.12)
struct MyStruct<'w, 's, 'a> {
commands: EntityCommands<'w, 's, 'a>,
}
// After (Bevy 0.13)
struct MyStruct<'a> {
commands: EntityCommands<'a>,
}
```
The method `EntityCommands::commands` now returns `Commands` rather than
`&mut Commands`.
```rust
// Before (Bevy 0.12)
let commands = entity_commands.commands();
commands.spawn(...);
// After (Bevy 0.13)
let mut commands = entity_commands.commands();
commands.spawn(...);
```
# Objective
Document a few common cases of which lifetime is required when using
SystemParam Derive
## Solution
Added a table in the doc comment
