# 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
- On some devices, UI buttons are not responsive
## Solution
- On device with a slower frame rate, touch event can start and end in
the frame rate
- When looking for a touch position, also look into the `just_pressed`
touches that are not cleared by the end event but only at the end of the
frame

# 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.
# Objective
- having different field names for `Camera2dBundle` and `Camera3dBundle`
implies that there is something different between these fields when
there is not
## Solution
- rename the field in `Camera3dBundle` to align with `Camera2dBundle`
## Migration Guide
- use the new `deband_dither` field name with `Camera3dBundle`, rather
than the old field name, `dither`
# Objective
Do #11829, but without breaking CI.
## Solution
Update to `toml_edit` v0.22, replace the deprecated function with the
the newer equivalent.
# Objective
- The `transform.translation` of a `TextBundle` in this example is
unnecessarily set to the same constant position over and over in each
`Update`. Newbies might be confused as to why this translation is being
performed over and over.
## Solution
- perform the translation only once, when the `Text2dBundle` is
instantiated
# Objective
Fixes#11964.
## Solution
Adds the `serde` feature to `bitflags` for `bevy_render`. This makes
`bevy_render` compile correctly when used alone.
---
## Changelog
- Fixed an issue where depending on `bevy_render` alone would fail to
compile.
# Objective
Improve code quality and performance
## Solution
Instead of using `plugin.downcast_ref::<T>().is_some()` in
`App::is_plugin_added`, use `plugin.is::<T>()`. Which is more performant
and cleaner.
# Objective
- Fixes#11960
- The compilation of `bevy_core_pipeline` failed with the `dds` feature
enabled
## Solution
- Enable the `dds` feature of `bevy_render` when enabling it for
`bevy_core_pipeline`
# Objective
`update_archetype_component_access` was removed from queries in #9774,
but some documentation still refers to it.
## Solution
Update the documentation. Since a bunch of these were in SAFETY comments
it would be nice if someone who knows the details better could check
that the rest of those comments are still valid.
# Objective
Right now, if you call `embedded_asset` with 2 arguments as a qualified
path it doesn't work (`bevy::asset::embedded_asset!(app, "foo.wgsl")` ->
"cannot find macro `embedded_asset` in this scope")
## Solution
Use `$crate::` in expansion for 2-arg case.
# Objective
- `#[reflect(FromWorld)]` was added to `ComponentB` somewhere between
`v0.12.1` and `v0.13.0`, but it is unnecessary
## Solution
- remove the unnecessary `FromWorld`
# Objective
- I hated having to do `Cuboid::new(1.0, 1.0, 1.0)` or
`Cuboid::from_size(Vec3::splat(1.0))` when there should be a much easier
way to do this.
## Solution
- Implemented a `from_length()` method that only takes in a single
float, and constructs a primitive of equal size in all directions.
- Ex:
```rs
// These:
Cuboid::new(1.0, 1.0, 1.0);
Cuboid::from_size(Vec3::splat(1.0));
// Are equivalent to this:
Cuboid::from_length(1.0);
```
- For the rest of the changed primitives:
```rs
Rectangle::from_length(1.0);
Plane3d::default().mesh().from_length(1.0);
```
# Objective
- revert a single-line change made to `examples/asset/asset_loading`
example between `v0.12.1` release and `v0.13.0` release which resulted
in a too-bright, washed-out rendering
## Solution
- reverted the changes made to this example between `v0.12.1` and
`v0.13.0`
# Objective
Another PR failed CI due to duplicate deps, and I noticed this one in
particular while scanning through the error messages.
I think this was missed in #11082.
## Solution
Bump `encase_derive_impl` dep in `bevy_encase_derive` to same version as
`encase` dep for `bevy_render`.
I spot-checked a few examples, and glanced at the
[changelog](<https://github.com/teoxoy/encase/blob/main/CHANGELOG.md#v070-2024-01-02>)
and I don't think there's anything to be concerned about, but I barely
know what this thing does.
# Objective
Fixes#11908
## Solution
- Remove the `naga_oil` dependency from `bevy_pbr`.
- We were doing a little dance to disable `glsl` support on not-wasm, so
incorporate that dance into `bevy_render`'s `Cargo.toml`.
They cause the number of texture bindings to overflow on those
platforms. Ultimately, we shouldn't unconditionally disable them, but
this fixes a crash blocking 0.13.
Closes#11885.
# Objective
Fixes two small quality issues:
1. With the new default ev100 exposure value, the irradiance intensity
was too low
2. The camera was rotating at a fixed speed (instead of a speed
multiplied by delta time), resulting in frame-rate dependent rotation
speed.
I did this during the prepass, but I neglected to do it during the
shadow map pass, causing a panic when directional lights with shadows
were enabled with lightmapped meshes present. This patch fixes the
issue.
Closes#11898.

# Objective
When registering and preregistering asset loaders, there would be a
`warn!` if multiple asset loaders use a given extension, and an `info!`
if multiple asset loaders load the same asset type. Since both of these
situations are individually fine, it was decided that these messages
should be removed.
## Solution
Replace both of these messages with a new `warn!` that notes that if
multiple asset loaders share the same asset type _and_ share extensions,
that the loader must be specified in the `.meta` file for those assets
in order to solve the ambiguity. This is a more useful message, since it
notes when a user must take special action / consideration.
# Objective
Fixes#11846
## Solution
Add a `synchronous_pipeline_compilation ` field to `RenderPlugin`,
defaulting to `false`.
Most of the diff is whitespace.
## Changelog
Added `synchronous_pipeline_compilation ` to `RenderPlugin` for
disabling async pipeline creation.
## Migration Guide
TODO: consider combining this with the guide for #11846
`RenderPlugin` has a new `synchronous_pipeline_compilation ` property.
The default value is `false`. Set this to `true` if you want to retain
the previous synchronous behavior.

This represents when the user has configured `ClearColorConfig::None` in
their application. If the clear color is `None`, we will always `Load`
instead of attempting to clear the attachment on the first call.
Fixes#11883.
# Objective
The new render graph labels do not (and cannot) implement normal
Reflect, which breaks spawning scenes with cameras (including GLTF
scenes). Likewise, the new `CameraMainTextureUsages` also does not (and
cannot) implement normal Reflect because it uses `wgpu::TextureUsages`
under the hood.
Fixes#11852
## Solution
This implements minimal "reflect value" for `CameraRenderGraph` and
`CameraMainTextureUsages` and registers the types, which satisfies our
spawn logic.
Note that this _does not_ fix scene serialization for these types, which
will require more significant changes. We will especially need to think
about how (and if) "interned labels" will fit into the scene system. For
the purposes of 0.13, I think this is the best we can do. Given that
this serialization issue is prevalent throughout Bevy atm, I'm ok with
adding a couple more to the pile. When we roll out the new scene system,
we will be forced to solve these on a case-by-case basis.
---
## Changelog
- Implement Reflect (value) for `CameraMainTextureUsages` and
`CameraRenderGraph`, and register those types.
# Objective
#10644 introduced nice "statically typed" labels that replace the old
strings. I would like to propose some changes to the names introduced:
* `SubGraph2d` -> `Core2d` and `SubGraph3d` -> `Core3d`. The names of
these graphs have been / should continue to be the "core 2d" graph not
the "sub graph 2d" graph. The crate is called `bevy_core_pipeline`, the
modules are still `core_2d` and `core_3d`, etc.
* `Labels2d` and `Labels3d`, at the very least, should not be plural to
follow naming conventions. A Label enum is not a "collection of labels",
it is a _specific_ Label. However I think `Label2d` and `Label3d` is
significantly less clear than `Node2d` and `Node3d`, so I propose those
changes here. I've done the same for `LabelsPbr` -> `NodePbr` and
`LabelsUi` -> `NodeUi`
Additionally, #10644 accidentally made one of the Camera2dBundle
constructors use the 3D graph instead of the 2D graph. I've fixed that
here.
---
## Changelog
* Renamed `SubGraph2d` -> `Core2d`, `SubGraph3d` -> `Core3d`, `Labels2d`
-> `Node2d`, `Labels3d` -> `Node3d`, `LabelsUi` -> `NodeUi`, `LabelsPbr`
-> `NodePbr`
# Objective
Provide a public replacement for `Into<MeshUniform>` trait impl which
was removed by #10231.
I made use of this in the `bevy_mod_outline` crate and will have to
duplicate this function if it's not accessible.
## Solution
Change the MeshUniform::new() method to be public.
# Objective
After adding configurable exposure, we set the default ev100 value to
`7` (indoor). This brought us out of sync with Blender's configuration
and defaults. This PR changes the default to `9.7` (bright indoor or
very overcast outdoors), as I calibrated in #11577. This feels like a
very reasonable default.
The other changes generally center around tweaking Bevy's lighting
defaults and examples to play nicely with this number, alongside a few
other tweaks and improvements.
Note that for artistic reasons I have reverted some examples, which
changed to directional lights in #11581, back to point lights.
Fixes#11577
---
## Changelog
- Changed `Exposure::ev100` from `7` to `9.7` to better match Blender
- Renamed `ExposureSettings` to `Exposure`
- `Camera3dBundle` now includes `Exposure` for discoverability
- Bumped `FULL_DAYLIGHT ` and `DIRECT_SUNLIGHT` to represent the
middle-to-top of those ranges instead of near the bottom
- Added new `AMBIENT_DAYLIGHT` constant and set that as the new
`DirectionalLight` default illuminance.
- `PointLight` and `SpotLight` now have a default `intensity` of
1,000,000 lumens. This makes them actually useful in the context of the
new "semi-outdoor" exposure and puts them in the "cinema lighting"
category instead of the "common household light" category. They are also
reasonably close to the Blender default.
- `AmbientLight` default has been bumped from `20` to `80`.
## Migration Guide
- The increased `Exposure::ev100` means that all existing 3D lighting
will need to be adjusted to match (DirectionalLights, PointLights,
SpotLights, EnvironmentMapLights, etc). Or alternatively, you can adjust
the `Exposure::ev100` on your cameras to work nicely with your current
lighting values. If you are currently relying on default intensity
values, you might need to change the intensity to achieve the same
effect. Note that in Bevy 0.12, point/spot lights had a different hard
coded ev100 value than directional lights. In Bevy 0.13, they use the
same ev100, so if you have both in your scene, the _scale_ between these
light types has changed and you will likely need to adjust one or both
of them.
# Objective
We recently got some neat new 2d shapes and the shapes are no longer
centered on the screen.
The hardcoded positions and colors are a pain to deal with when a new
shape is added.
## Solution
Delete a bunch of code and position shapes evenly. Assign colors evenly
too.

# Objective
Fix https://github.com/bevyengine/bevy/issues/11577.
## Solution
Fix the examples, add a few constants to make setting light values
easier, and change the default lighting settings to be more realistic.
(Now designed for an overcast day instead of an indoor environment)
---
I did not include any example-related changes in here.
## Changelogs (not including breaking changes)
### bevy_pbr
- Added `light_consts` module (included in prelude), which contains
common lux and lumen values for lights.
- Added `AmbientLight::NONE` constant, which is an ambient light with a
brightness of 0.
- Added non-EV100 variants for `ExposureSettings`'s EV100 constants,
which allow easier construction of an `ExposureSettings` from a EV100
constant.
## Breaking changes
### bevy_pbr
The several default lighting values were changed:
- `PointLight`'s default `intensity` is now `2000.0`
- `SpotLight`'s default `intensity` is now `2000.0`
- `DirectionalLight`'s default `illuminance` is now
`light_consts::lux::OVERCAST_DAY` (`1000.`)
- `AmbientLight`'s default `brightness` is now `20.0`
# Objective
- The current implementations for `&Visibility == Visibility` and
`Visibility == &Visibility` are ambiguous, so they raise a warning for
being unconditionally recursive.
- `TaskPool`'s `LOCAL_EXECUTOR` thread local calls a `const` constructor
in a non-`const` context.
## Solution
- Make `&Visibility == Visibility` and `Visibility == &Visibility`
implementations use `Visibility == Visibility`.
- Wrap `LocalExecutor::new` in a special `const` block supported by
[`thread_local`](https://doc.rust-lang.org/stable/std/macro.thread_local.html).

# Objective
- There are multiple instances of `let Some(x) = ... else { None };`
throughout the project.
- Because `Option<T>` implements
[`Try`](https://doc.rust-lang.org/stable/std/ops/trait.Try.html), it can
use the question mark `?` operator.
## Solution
- Use question mark operator instead of `let Some(x) = ... else { None
}`.

There was another PR that did a similar thing a few weeks ago, but I
couldn't find it.
I just implemented this to record a video for the new blog post, but I
figured it would also make a good dedicated example. This also allows us
to remove a lot of code from the 2d/3d gizmo examples since it
supersedes this portion of code.
Depends on: https://github.com/bevyengine/bevy/pull/11699
# Objective
I tried using `insert_gizmo_group` to configure my physics gizmos in a
bevy_xpbd example, but was surprised to see that nothing happened. I
found out that the method does *not* overwrite gizmo groups that have
already been initialized (with `init_gizmo_group`). This is unexpected,
since methods like `insert_resource` *do* overwrite.
## Solution
Insert the configuration even if it has already been initialized.
# Objective
`RenderMeshInstance::material_bind_group_id` is only set from
`queue_material_meshes::<M>`. this field is used (only) for determining
batch groups, so some items may be batched incorrectly if they have
never been in the camera's view or if they don't use the Material
abstraction.
in particular, shadow views render more meshes than the main camera, and
currently batch some meshes where the object has never entered the
camera view together. this is quite hard to trigger, but should occur in
a scene with out-of-view alpha-mask materials (so that the material
instance actually affects the shadow) in the path of a light.
this is also a footgun for custom pipelines: failing to set the
material_bind_group_id will result in all meshes being batched together
and all using the closest/furthest material to the camera (depending on
sort order).
## Solution
- queue_shadows now sets the material_bind_group_id correctly
- `MeshPipeline` doesn't attempt to batch meshes if the
material_bind_group_id has not been set. custom pipelines still need to
set this field to take advantage of batching, but will at least render
correctly if it is not set
