# Objective
Fixes#11821.
## Solution
* Run `System::apply_deferred` in `System::run` after executing the
system.
* Switch to using `System::run_unsafe` in `SingleThreadedExecutor` to
preserve the current behavior.
* Remove the `System::apply_deferred` in `SimpleExecutor` as it's now
redundant.
* Remove the `System::apply_deferred` when running one-shot systems, as
it's now redundant.
---
## Changelog
Changed: `System::run` will now immediately apply deferred system params
after running the system.
## Migration Guide
`System::run` will now always run `System::apply_deferred` immediately
after running the system now. If you were running systems and then
applying their deferred buffers at a later point in time, you can
eliminate the latter.
```rust
// in 0.13
system.run(world);
// .. sometime later ...
system.apply_deferred(world);
// in 0.14
system.run(world);

# Objective
Since #9822, `SimpleExecutor` panics when an automatic sync point is
inserted:
```rust
let mut sched = Schedule::default();
sched.set_executor_kind(ExecutorKind::Simple);
sched.add_systems((|_: Commands| (), || ()).chain());
sched.run(&mut World::new());
```
```
System's param_state was not found. Did you forget to initialize this system before running it?
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Encountered a panic in system `bevy_ecs::schedule::executor::apply_deferred`!
```
## Solution
Don't try to run the `apply_deferred` system.
# Objective
Fixes Skyboxes on WebGL, which broke in Bevy 0.13 due to the addition of
the `brightness` uniform, when previously the skybox pipeline only had
view and global uniforms.

note: label = `skybox_pipeline`
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)
I've added 3 conditional fields to `SkyboxUniforms`.
# Objective
- Example reflection_probe is not frame rate independent

# 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
ensuring consistent API implementation.
## Solution
Created a `pub(crate)` trait `StandardColor` which has all the
requirements for a typical color space (e.g, `Srgba`, `Color`, etc.).
---
## Changelog
- Implemented traits missing from certain color spaces.
## Migration Guide
_No migration required_
# Objective
Improve code quality and prevent bugs.
## Solution
I removed the unnecessary wildcards from `<LogPlugin as Plugin>::build`.
I also changed the warnings that would occur if the subscriber/logger
was already set into errors.
# Objective
This provides a new set of color types and operations for Bevy.
Fixes: #10986#1402
## Solution
The new crate provides a set of distinct types for various useful color
spaces, along with utilities for manipulating and converting colors.
This is not a breaking change, as no Bevy APIs are modified (yet).

Fix rendering on iOS Simulators.
iOS Simulator doesn't support the capability CUBE_ARRAY_TEXTURES, since
0.13 this started to make iOS Simulator not render anything with the
following message being outputted:
```

## Solution
- Split up NO_ARRAY_TEXTURES_SUPPORT into both NO_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.

## Objective
Always have `some_system.into_system().type_id() ==
some_system.into_system_set().system_type().unwrap()`.
System sets have a `fn system_type() -> Option<TypeId>` that is
implemented by `SystemTypeSet` to returning the TypeId of the system's
function type. This was implemented in
https://github.com/bevyengine/bevy/pull/7715 and is used in
`bevy_mod_debugdump` to handle `.after(function)` constraints.
Back then, `System::type_id` always also returned the type id of the
function item, not of `FunctionSystem<M, F>`.
https://github.com/bevyengine/bevy/pull/11728 changes the behaviour of
`System::type_id` so that it returns the id of the
`FunctionSystem`/`ExclusiveFunctionSystem` wrapper, but it did not
change `SystemTypeSet::system_type`, so doing the lookup breaks in
`bevy_mod_debugdump`.
## Solution
Change `IntoSystemSet` for functions to return a
`SystemTypeSet<FunctionSystem>` /
`SystemTypeSet<ExclusiveFunctionSystem>` instead of `SystemTypeSet<F>`.
# Objective
- Globals are supposed to be available in vertex shader but that was
mistakenly removed in 0.13
## Solution
- Configure the visibility of the globals correctly
Fixes https://github.com/bevyengine/bevy/issues/12015
# Objective
- The file asset source currently creates the `imported_assets/Default`
directory with relative path, which leads to wrongly created directories
when the executable is run with a working directory different from the
project root.
## Solution

This PR adds some missing mime types to the
`ImageFormat::from_mime_type` method. As discussed [in this comment on
the Discord Bevy
community](https://discord.com/channels/691052431525675048/691052431974465548/1209904290227949729):
> It's strange that Bevy supports parsing `ImageFormat::WebP` from a
.webp str extension in the method below, but not from the mime type.
>
> In comparison, the image crate does parse it:
https://github.com/image-rs/image/blob/master/src/image.rs#L170
# Solution
For each of the missing mime types, I added them based on the
`ImageFormat::from_mime_type` of the image crate:
https://github.com/image-rs/image/blob/master/src/image.rs#L209, except
for `ImageFormat::Basis` and `ImageFormat::Ktx2` which are not present
in the image crate, and I ignore if they have a mime type or not*
\* apparently nowadays there is an official mime type: `image/ktx2`
https://www.iana.org/assignments/media-types/image/ktx2
Any feedback is welcome! I thought of refactoring a bit more and
delegating the mime type parsing to the image crate (and possibly the
same for extensions), let me know if that's desired 🙂

# Objective
- Closes#11985
## Solution
- alpha.rs has been moved from bevy_pbr into bevy_render; bevy_pbr and
bevy_gltf now access `AlphaMode` through bevy_render.
---
## Migration Guide
In the present implementation, external consumers of `AlphaMode` will
have to access it through bevy_render rather than through bevy_pbr,
changing their import from `bevy_pbr::AlphaMode` to
`bevy_render::alpha::AlphaMode` (or the corresponding glob import from
`bevy_pbr::prelude::*` to `bevy_render::prelude::*`).
## Uncertainties
Some remaining things from this that I am uncertain about:
- Here, the `app.register_type<AlphaMode>()` call has been moved from
`PbrPlugin` to `RenderPlugin`; I'm not sure if this is quite right, and
I was unable to find any direct relationship between `PbrPlugin` and
`RenderPlugin`.
- `AlphaMode` was placed in the prelude of bevy_render. I'm not certain
that this is actually appropriate.
- bevy_pbr does not re-export `AlphaMode`, which makes this a breaking
change for external consumers.
Any of these things could be easily changed; I'm just not confident that
I necessarily adopted the right approach in these (known) ways since
this codebase and ecosystem is quite new to me.
Adopted #8266, so copy-pasting the description from there:
# Objective
Support the KHR_texture_transform extension for the glTF loader.
- Fixes#6335
- Fixes#11869
- Implements part of #11350
- Implements the GLTF part of #399
## Solution
As is, this only supports a single transform. Looking at Godot's source,
they support one transform with an optional second one for detail, AO,
and emission. glTF specifies one per texture. The public domain
materials I looked at seem to share the same transform. So maybe having
just one is acceptable for now. I tried to include a warning if multiple
different transforms exist for the same material.
Note the gltf crate doesn't expose the texture transform for the normal
and occlusion textures, which it should, so I just ignored those for
now. (note by @janhohenheim: this is still the case)
Via `cargo run --release --example scene_viewer
~/src/clone/glTF-Sample-Models/2.0/TextureTransformTest/glTF/TextureTransformTest.gltf`:
## Changelog
Support for the
[KHR_texture_transform](https://github.com/KhronosGroup/glTF/tree/main/extensions/2.0/Khronos/KHR_texture_transform)
extension added. Texture UVs that were scaled, rotated, or offset in a
GLTF are now properly handled.

# Objective
If multiple cameras render to the same target with MSAA enabled, only
the first and the last camera output will appear in the final output*.
This is because each camera maintains a separate flag to track the
active main texture. The first camera renders to texture A and all
subsequent cameras first write-back from A and then render into texture
B. Hence, camera 3 onwards will overwrite the work of the previous
camera.
\* This would manifest slightly differently if there were other calls to
post_process_write() in a more complex setup.
The is a functional regression from Bevy 0.12.
## Solution
The flag which tracks the active main texture should be shared between
cameras with the same `NormalizedRenderTarget`. Add the
`Arc<AtomicUsize>` to the existing per-target cache.
# Objective
- Save 16 bytes per MeshUniform in uniform/storage buffers.
## Solution
- Reorder members of MeshUniform to capitalise on alignment and size
rules for tighter data packing. Before the size of a MeshUniform was 160
bytes, and after it is 144 bytes, saving 16 bytes of unused padding for
alignment.
---
## Changelog
- Reduced the size of MeshUniform by 16 bytes.

Since https://github.com/bevyengine/bevy-website/pull/880, the old book

# Objective
While doing a bunch of testing on examples, I noticed that this
particular example had lots of room for improvement. This example is
shown in example showcase, so it might as well look nice.
- The "overflow containers" have no vertical separation from each other
- The "overflow containers" are aligned awkwardly
- The instructions say you can "toggle" overflow, but it's actually
cycling through various overflow modes, with no indication of which mode
is currently active.
- The UI structure could be simplified
## Solution
- Simplify the UI structure by
- Moving the instructions into an absolutely positioned node, which we
do in most other examples with instructions
- Using a grid layout and removing some unnecessary containers
- Show the current overflow mode
- Add a gap between the overflow containers
- Other misc cleanup

# Objective
* Fixes#11932 (performance impact when stepping is disabled)
## Solution
The `Option<FixedBitSet>` argument added to `ScheduleExecutor::run()` in
#8453 caused a measurable performance impact even when stepping is
disabled. This can be seen by the benchmark of running `Schedule:run()`
on an empty schedule in a tight loop
(https://github.com/bevyengine/bevy/issues/11932#issuecomment-1950970236).
I was able to get the same performance results as on 0.12.1 by changing
the argument
`ScheduleExecutor::run()` from `Option<FixedBitSet>` to
`Option<&FixedBitSet>`. The down-side of this change is that
`Schedule::run()` now takes about 6% longer (3.7319 ms vs 3.9855ns) when
stepping is enabled
---
## Changelog
* Change `ScheduleExecutor::run()` `_skipped_systems` from
`Option<FixedBitSet>` to `Option<&FixedBitSet>`
* Added a few benchmarks to measure `Schedule::run()` performance with
various executors
# Objective
- Closes#9384.
## Solution
- Make the movement speed of the `CameraController` adjustable with the
scroll wheel as mentioned
[here](https://github.com/bevyengine/bevy/issues/9384#issuecomment-1668957931).
The speed use an exponential progression (10% increase per scroll tick
by default) to allow adapting the speed to different scales.
- For the `scene_viewer` example, make the default speed proportional to
the size of the scene using what's computed for the default camera
placement. This gives a good enough default to fly over the scene from
the outside. I don't think there's a good way to get a default speed
fitting for all scenes since some are meant to be viewed from outside
while other are traversable environments.
# Objective
Presently, it is possible to cause the `text_input` example to panic by
pressing enter too quickly. This happens because, under these
circumstances, the `listen_keyboard_input_events` system spawns multiple
text entry entities where the `listen_received_character_events` system
expects there to only ever be one. As this is an example this PR aims to
highlight this risk and mitigate it.
## Solution
Modify the example so that if a text entry has been spawned already
during this run of the system then further Enter input events are
ignored this run.
# Objective
- Gltf loader now shows which file is missing pre baked tangents
- Fixes#11831
## Solution
- The file name is shown in the error message
- What changed as a result of this PR?
### Changed:
- Gltf loader now shows which file is missing pre baked tangents
- If this PR is a breaking change (relative to the last release of
Bevy), describe how a user might need to migrate their code to support
these changes
- Simply adding new functionality is not a breaking change.
- Fixing behavior that was definitely a bug, rather than a questionable
design choice is not a breaking change.
# Objective
Currently, the `ambiguous_names` hash set in `TypeRegistry` is used to
keep track of short type names that are ambiguous, and to require the
use of long type names for these types.
However, there's no way for the consumer of `TypeRegistry` to known
whether a given call to `get_with_short_type_path()` or
`get_with_short_type_path_mut()` failed because a type was not
registered at all, or because the short name is ambiguous.
This can be used, for example, for better error reporting to the user by
an editor tool. Here's some code that uses this, from my remote protocol
exploration branch:
```rust
let type_registration = type_registry
.get_with_type_path(component_name)
.or_else(|| registry.get_with_short_type_path(component_name))
.ok_or_else(|| {
if type_registry.is_ambiguous(component_name) {
BrpError::ComponentAmbiguous(component_name.clone())
} else {
BrpError::MissingTypeRegistration(component_name.clone())
}
})?
```
## Solution
- Introduces a `is_ambiguous()` method.
- Also drive-by fixes two documentation comments that had broken links.
---
## Changelog
- Added a `TypeRegistry::is_ambiguous()` method, for checking whether a
given short type path is ambiguous (e.g. `MyType` potentially matching
either `some_crate::MyType` or `another_crate::MyType`)

# Objective
Implement Debug trait for SpriteBundle and SpriteSheetBundle
It's helpful and other basic bundles like TransformBundle and
VisibilityBundle already implement this trait
# Objective
There's a repeating pattern of `ThreadLocal<Cell<Vec<T>>>` which is very
useful for low overhead, low contention multithreaded queues that have
cropped up in a few places in the engine. This pattern is surprisingly
useful when building deferred mutation across multiple threads, as noted
by it's use in `ParallelCommands`.
However, `ThreadLocal<Cell<Vec<T>>>` is not only a mouthful, it's also
hard to ensure the thread-local queue is replaced after it's been
temporarily removed from the `Cell`.
## Solution
Wrap the pattern into `bevy_utils::Parallel<T>` which codifies the
entire pattern and ensures the user follows the contract. Instead of
fetching indivdual cells, removing the value, mutating it, and replacing
it, `Parallel::get` returns a `ParRef<'a, T>` which contains the
temporarily removed value and a reference back to the cell, and will
write the mutated value back to the cell upon being dropped.
I would like to use this to simplify the remaining part of #4899 that
has not been adopted/merged.

# Objective
Bevy's animation system currently does tree traversals based on `Name`
that aren't necessary. Not only do they require in unsafe code because
tree traversals are awkward with parallelism, but they are also somewhat
slow, brittle, and complex, which manifested itself as way too many
queries in #11670.
# Solution
Divide animation into two phases: animation *advancement* and animation
*evaluation*, which run after one another. *Advancement* operates on the
`AnimationPlayer` and sets the current animation time to match the game
time. *Evaluation* operates on all animation bones in the scene in
parallel and sets the transforms and/or morph weights based on the time
and the clip.
To do this, we introduce a new component, `AnimationTarget`, which the
asset loader places on every bone. It contains the ID of the entity
containing the `AnimationPlayer`, as well as a UUID that identifies
which bone in the animation the target corresponds to. In the case of
glTF, the UUID is derived from the full path name to the bone. The rule
that `AnimationTarget`s are descendants of the entity containing
`AnimationPlayer` is now just a convention, not a requirement; this
allows us to eliminate the unsafe code.
# Migration guide
* `AnimationClip` now uses UUIDs instead of hierarchical paths based on
the `Name` component to refer to bones. This has several consequences:
- A new component, `AnimationTarget`, should be placed on each bone that
you wish to animate, in order to specify its UUID and the associated
`AnimationPlayer`. The glTF loader automatically creates these
components as necessary, so most uses of glTF rigs shouldn't need to
change.
- Moving a bone around the tree, or renaming it, no longer prevents an
`AnimationPlayer` from affecting it.
- Dynamically changing the `AnimationPlayer` component will likely
require manual updating of the `AnimationTarget` components.
* Entities with `AnimationPlayer` components may now possess descendants
that also have `AnimationPlayer` components. They may not, however,
animate the same bones.
* As they aren't specific to `TypeId`s,
`bevy_reflect::utility::NoOpTypeIdHash` and
`bevy_reflect::utility::NoOpTypeIdHasher` have been renamed to
`bevy_reflect::utility::NoOpHash` and
`bevy_reflect::utility::NoOpHasher` respectively.
