This is not used directly within the rendering code.
# Objective
- Remove extraneous dependency on `wgpu-hal` as it is not used.
## Solution
- The dependency has been removed and should have no externally visible
impact.
# Objective
The `QueryParIter::for_each_mut` function is required when doing
parallel iteration with mutable queries.
This results in an unfortunate stutter:
`query.par_iter_mut().par_for_each_mut()` ('mut' is repeated).
## Solution
- Make `for_each` compatible with mutable queries, and deprecate
`for_each_mut`. In order to prevent `for_each` from being called
multiple times in parallel, we take ownership of the QueryParIter.
---
## Changelog
- `QueryParIter::for_each` is now compatible with mutable queries.
`for_each_mut` has been deprecated as it is now redundant.
## Migration Guide
The method `QueryParIter::for_each_mut` has been deprecated and is no
longer functional. Use `for_each` instead, which now supports mutable
queries.
```rust
// Before:
query.par_iter_mut().for_each_mut(|x| ...);
// After:
query.par_iter_mut().for_each(|x| ...);
```
The method `QueryParIter::for_each` now takes ownership of the
`QueryParIter`, rather than taking a shared reference.
```rust
// Before:
let par_iter = my_query.par_iter().batching_strategy(my_batching_strategy);
par_iter.for_each(|x| {
// ...Do stuff with x...
par_iter.for_each(|y| {
// ...Do nested stuff with y...
});
});
// After:
my_query.par_iter().batching_strategy(my_batching_strategy).for_each(|x| {
// ...Do stuff with x...
my_query.par_iter().batching_strategy(my_batching_strategy).for_each(|y| {
// ...Do nested stuff with y...
});
});
```
# Objective
Fixes#9121
Context:
- `ImageTextureLoader` depends on `RenderDevice` to work out which
compressed image formats it can support
- `RenderDevice` is initialised by `RenderPlugin`
- https://github.com/bevyengine/bevy/pull/8336 made `RenderPlugin`
initialisation async
- This caused `RenderDevice` to be missing at the time of
`ImageTextureLoader` initialisation, which in turn meant UASTC encoded
ktx2 textures were being converted to unsupported formats, and thus
caused panics
## Solution
- Delay `ImageTextureLoader` initialisation
---
## Changelog
- Moved `ImageTextureLoader` initialisation from `ImagePlugin::build()`
to `ImagePlugin::finish()`
- Default to `CompressedImageFormats::NONE` if `RenderDevice` resource
is missing

# Objective
Fix#8936.
## Solution
Stop using `unwrap` in the core pipelined rendering logic flow.
Separately also scoped the `sub app` span to just running the render app
instead of including the blocking send.
Current unknowns: should we use `std::panic::catch_unwind` around
running the render app? Other engine threads use it defensively, but
we're letting it bubble up here, and a user-created panic could cause a
deadlock if it kills the thread.
---
## Changelog
Fixed: Pipelined rendering should no longer have spurious panics upon
app exit.
# Objective
- Add a type for uploading a Rust `Vec<T>` to a GPU `array<T>`.
- Makes progress towards https://github.com/bevyengine/bevy/issues/89.
## Solution
- Port @superdump's `BatchedUniformBuffer` to bevy main, as a fallback
for WebGL2, which doesn't support storage buffers.
- Rather than getting an `array<T>` in a shader, you get an `array<T,
N>`, and have to rebind every N elements via dynamic offsets.
- Add `GpuArrayBuffer` to abstract over
`StorageBuffer<Vec<T>>`/`BatchedUniformBuffer`.
## Future Work
Add a shader macro kinda thing to abstract over the following
automatically:
https://github.com/bevyengine/bevy/pull/8204#pullrequestreview-1396911727
---
## Changelog
* Added `GpuArrayBuffer`, `GpuComponentArrayBufferPlugin`,
`GpuArrayBufferable`, and `GpuArrayBufferIndex` types.
* Added `DynamicUniformBuffer::new_with_alignment()`.

# Objective
AssetPath shader imports check if the shader is added using the path
without quotes. this causes them to be re-added even if already present,
which can cause previous dependents to get unloaded leading to a
"missing import" error.

already added to correctly use the quoted name.
# Objective

## Changelog
- Changed `Camera::physical_viewport_rect` return type from `(UVec2,
UVec2)` to `URect`

# Objective
Fix typos throughout the project.
## Solution
[`typos`](https://github.com/crate-ci/typos) project was used for
scanning, but no automatic corrections were applied. I checked
everything by hand before fixing.
Most of the changes are documentation/comments corrections. Also, there
are few trivial changes to code (variable name, pub(crate) function name
and a few error/panic messages).
## Unsolved
`bevy_reflect_derive` has
[typo](1b51053f19/crates/bevy_reflect/bevy_reflect_derive/src/type_path.rs (L76))
in enum variant name that I didn't fix. Enum is `pub(crate)`, so there
shouldn't be any trouble if fixed. However, code is tightly coupled with
macro usage, so I decided to leave it for more experienced contributor
just in case.
I created this manually as Github didn't want to run CI for the
workflow-generated PR. I'm guessing we didn't hit this in previous
releases because we used bors.

---
Resolves#4597
Full details and motivation can be found in the RFC, but here's a brief
summary.
`FromReflect` is a very powerful and important trait within the
reflection API. It allows Dynamic types (e.g., `DynamicList`, etc.) to
be formed into Real ones (e.g., `Vec<i32>`, etc.).
This mainly comes into play concerning deserialization, where the
reflection deserializers both return a `Box<dyn Reflect>` that almost
always contain one of these Dynamic representations of a Real type. To
convert this to our Real type, we need to use `FromReflect`.
It also sneaks up in other ways. For example, it's a required bound for
`T` in `Vec<T>` so that `Vec<T>` as a whole can be made `FromReflect`.
It's also required by all fields of an enum as it's used as part of the
`Reflect::apply` implementation.
So in other words, much like `GetTypeRegistration` and `Typed`, it is
very much a core reflection trait.
The problem is that it is not currently treated like a core trait and is
not automatically derived alongside `Reflect`. This makes using it a bit
cumbersome and easy to forget.
## Solution
Automatically derive `FromReflect` when deriving `Reflect`.
Users can then choose to opt-out if needed using the
`#[reflect(from_reflect = false)]` attribute.
```rust
#[derive(Reflect)]
struct Foo;
#[derive(Reflect)]
#[reflect(from_reflect = false)]
struct Bar;
fn test<T: FromReflect>(value: T) {}
test(Foo); // <-- OK
test(Bar); // <-- Panic! Bar does not implement trait `FromReflect`
```
#### `ReflectFromReflect`
This PR also automatically adds the `ReflectFromReflect` (introduced in
#6245) registration to the derived `GetTypeRegistration` impl— if the
type hasn't opted out of `FromReflect` of course.
<details>
<summary><h4>Improved Deserialization</h4></summary>
> **Warning**
> This section includes changes that have since been descoped from this
PR. They will likely be implemented again in a followup PR. I am mainly
leaving these details in for archival purposes, as well as for reference
when implementing this logic again.
And since we can do all the above, we might as well improve
deserialization. We can now choose to deserialize into a Dynamic type or
automatically convert it using `FromReflect` under the hood.
`[Un]TypedReflectDeserializer::new` will now perform the conversion and
return the `Box`'d Real type.
`[Un]TypedReflectDeserializer::new_dynamic` will work like what we have
now and simply return the `Box`'d Dynamic type.
```rust
// Returns the Real type
let reflect_deserializer = UntypedReflectDeserializer::new(®istry);
let mut deserializer = ron:🇩🇪:Deserializer::from_str(input)?;
let output: SomeStruct = reflect_deserializer.deserialize(&mut deserializer)?.take()?;
// Returns the Dynamic type
let reflect_deserializer = UntypedReflectDeserializer::new_dynamic(®istry);
let mut deserializer = ron:🇩🇪:Deserializer::from_str(input)?;
let output: DynamicStruct = reflect_deserializer.deserialize(&mut deserializer)?.take()?;
```
</details>
---
## Changelog
* `FromReflect` is now automatically derived within the `Reflect` derive
macro
* This includes auto-registering `ReflectFromReflect` in the derived
`GetTypeRegistration` impl
* ~~Renamed `TypedReflectDeserializer::new` and
`UntypedReflectDeserializer::new` to
`TypedReflectDeserializer::new_dynamic` and
`UntypedReflectDeserializer::new_dynamic`, respectively~~ **Descoped**
* ~~Changed `TypedReflectDeserializer::new` and
`UntypedReflectDeserializer::new` to automatically convert the
deserialized output using `FromReflect`~~ **Descoped**
## Migration Guide
* `FromReflect` is now automatically derived within the `Reflect` derive
macro. Items with both derives will need to remove the `FromReflect`
one.
```rust
// OLD
#[derive(Reflect, FromReflect)]
struct Foo;
// NEW
#[derive(Reflect)]
struct Foo;
```
If using a manual implementation of `FromReflect` and the `Reflect`
derive, users will need to opt-out of the automatic implementation.
```rust
// OLD
#[derive(Reflect)]
struct Foo;
impl FromReflect for Foo {/* ... */}
// NEW
#[derive(Reflect)]
#[reflect(from_reflect = false)]
struct Foo;
impl FromReflect for Foo {/* ... */}
```

<summary><h4>Removed Migrations</h4></summary>
> **Warning**
> This section includes changes that have since been descoped from this
PR. They will likely be implemented again in a followup PR. I am mainly
leaving these details in for archival purposes, as well as for reference
when implementing this logic again.
* The reflect deserializers now perform a `FromReflect` conversion
internally. The expected output of `TypedReflectDeserializer::new` and
`UntypedReflectDeserializer::new` is no longer a Dynamic (e.g.,
`DynamicList`), but its Real counterpart (e.g., `Vec<i32>`).
```rust
let reflect_deserializer =
UntypedReflectDeserializer::new_dynamic(®istry);
let mut deserializer = ron:🇩🇪:Deserializer::from_str(input)?;
// OLD
let output: DynamicStruct = reflect_deserializer.deserialize(&mut
deserializer)?.take()?;
// NEW
let output: SomeStruct = reflect_deserializer.deserialize(&mut
deserializer)?.take()?;
```
Alternatively, if this behavior isn't desired, use the
`TypedReflectDeserializer::new_dynamic` and
`UntypedReflectDeserializer::new_dynamic` methods instead:
```rust
// OLD
let reflect_deserializer = UntypedReflectDeserializer::new(®istry);
// NEW
let reflect_deserializer =
UntypedReflectDeserializer::new_dynamic(®istry);
```

# Objective
operate on naga IR directly to improve handling of shader modules.
- give codespan reporting into imported modules
- allow glsl to be used from wgsl and vice-versa
the ultimate objective is to make it possible to
- provide user hooks for core shader functions (to modify light
behaviour within the standard pbr pipeline, for example)
- make automatic binding slot allocation possible
but ... since this is already big, adds some value and (i think) is at
feature parity with the existing code, i wanted to push this now.
## Solution
i made a crate called naga_oil (https://github.com/robtfm/naga_oil -
unpublished for now, could be part of bevy) which manages modules by
- building each module independantly to naga IR
- creating "header" files for each supported language, which are used to
build dependent modules/shaders
- make final shaders by combining the shader IR with the IR for imported
modules
then integrated this into bevy, replacing some of the existing shader
processing stuff. also reworked examples to reflect this.
## Migration Guide
shaders that don't use `#import` directives should work without changes.
the most notable user-facing difference is that imported
functions/variables/etc need to be qualified at point of use, and
there's no "leakage" of visible stuff into your shader scope from the
imports of your imports, so if you used things imported by your imports,
you now need to import them directly and qualify them.
the current strategy of including/'spreading' `mesh_vertex_output`
directly into a struct doesn't work any more, so these need to be
modified as per the examples (e.g. color_material.wgsl, or many others).
mesh data is assumed to be in bindgroup 2 by default, if mesh data is
bound into bindgroup 1 instead then the shader def `MESH_BINDGROUP_1`
needs to be added to the pipeline shader_defs.
# Objective
- Closes#7323
- Reduce texture blurriness for TAA
## Solution
- Add a `MipBias` component and view uniform.
- Switch material `textureSample()` calls to `textureSampleBias()`.
- Add a `-1.0` bias to TAA.
---
## Changelog
- Added `MipBias` camera component, mostly for internal use.

# Objective
- Add morph targets to `bevy_pbr` (closes#5756) & load them from glTF
- Supersedes #3722
- Fixes#6814
[Morph targets][1] (also known as shape interpolation, shape keys, or
blend shapes) allow animating individual vertices with fine grained
controls. This is typically used for facial expressions. By specifying
multiple poses as vertex offset, and providing a set of weight of each
pose, it is possible to define surprisingly realistic transitions
between poses. Blending between multiple poses also allow composition.
Morph targets are part of the [gltf standard][2] and are a feature of
Unity and Unreal, and babylone.js, it is only natural to implement them
in bevy.
## Solution
This implementation of morph targets uses a 3d texture where each pixel
is a component of an animated attribute. Each layer is a different
target. We use a 2d texture for each target, because the number of
attribute×components×animated vertices is expected to always exceed the
maximum pixel row size limit of webGL2. It copies fairly closely the way
skinning is implemented on the CPU side, while on the GPU side, the
shader morph target implementation is a relatively trivial detail.
We add an optional `morph_texture` to the `Mesh` struct. The
`morph_texture` is built through a method that accepts an iterator over
attribute buffers.
The `MorphWeights` component, user-accessible, controls the blend of
poses used by mesh instances (so that multiple copy of the same mesh may
have different weights), all the weights are uploaded to a uniform
buffer of 256 `f32`. We limit to 16 poses per mesh, and a total of 256
poses.

* Thanks to `superdump` and `james7132` for guidance and help figuring
out stuff
## Future work
- Handling of less and more attributes (eg: animated uv, animated
arbitrary attributes)
- Dynamic pose allocation (so that zero-weighted poses aren't uploaded
to GPU for example, enables much more total poses)
- Better animation API, see #8357
----
## Changelog
- Add morph targets to bevy meshes
- Support up to 64 poses per mesh of individually up to 116508 vertices,
animation currently strictly limited to the position, normal and tangent
attributes.
- Load a morph target using `Mesh::set_morph_targets`
- Add `VisitMorphTargets` and `VisitMorphAttributes` traits to
`bevy_render`, this allows defining morph targets (a fairly complex and
nested data structure) through iterators (ie: single copy instead of
passing around buffers), see documentation of those traits for details
- Add `MorphWeights` component exported by `bevy_render`
- `MorphWeights` control mesh's morph target weights, blending between
various poses defined as morph targets.
- `MorphWeights` are directly inherited by direct children (single level
of hierarchy) of an entity. This allows controlling several mesh
primitives through a unique entity _as per GLTF spec_.
- Add `MorphTargetNames` component, naming each indices of loaded morph
targets.
- Load morph targets weights and buffers in `bevy_gltf`
- handle morph targets animations in `bevy_animation` (previously, it
was a `warn!` log)
- Add the `MorphStressTest.gltf` asset for morph targets testing, taken
from the glTF samples repo, CC0.
- Add morph target manipulation to `scene_viewer`
- Separate the animation code in `scene_viewer` from the rest of the
code, reducing `#[cfg(feature)]` noise
- Add the `morph_targets.rs` example to show off how to manipulate morph
targets, loading `MorpStressTest.gltf`
## Migration Guide
- (very specialized, unlikely to be touched by 3rd parties)
- `MeshPipeline` now has a single `mesh_layouts` field rather than
separate `mesh_layout` and `skinned_mesh_layout` fields. You should
handle all possible mesh bind group layouts in your implementation
- You should also handle properly the new `MORPH_TARGETS` shader def and
mesh pipeline key. A new function is exposed to make this easier:
`setup_moprh_and_skinning_defs`
- The `MeshBindGroup` is now `MeshBindGroups`, cached bind groups are
now accessed through the `get` method.

# Objective
Improve the documentation relating to windows, and update the parts that
have not been updated since version 0.8.
Version 0.9 introduced `Window` as a component, before that
`WindowDescriptor` (which would become `Window` later) was used to store
information about how a window will be created. Since version 0.9, from
my understanding, this information will also be synchronised with the
current state of the window, and can be used to modify this state.
However, some of the documentation has not been updated to reflect that,
here is an example:
https://docs.rs/bevy/0.8.0/bevy/window/enum.WindowMode.html /
https://docs.rs/bevy/latest/bevy/window/enum.WindowMode.html (notice
that the verb "Creates" is still there).
This PR aims at improving the documentation relating to windows.
## Solution
- Change "will" for "should" when relevant, "should" implies that the
information should in both direction (from the window state to the
`Window` component and vice-versa) and can be used to get and set, will
implies it is only used to set a state.
- Remove references to "creation" or be more clear about it.
- Reference back the `Window` component for most of its sub-structs.
- Clarify what needs to be clarified
- A lot of other minor changes, including fixing the link to W3schools
in `bevy_winit`
## Warning
Please note that my knowledge about how winit and bevy_winit work is
limited and some of the informations I added in the doc may be
inaccurate. A person who knows better how it works should review some of
my claims, in particular:
- How fullscreen works:
https://github.com/bevyengine/bevy/pull/8858#discussion_r1232413155
- How WindowResolution / sizes work:
https://github.com/bevyengine/bevy/pull/8858#discussion_r1233010719
- What happens when `WindowPosition` is set to `Centered` or
`Automatic`. From my understanding of the code, it should always be set
back to `At`, but is it really the case? For example [when creating the
window](https://github.com/bevyengine/bevy/blob/main/crates/bevy_winit/src/winit_windows.rs#L74),
or when [a `WindowEvent::Moved` is
triggered](https://github.com/bevyengine/bevy/blob/main/crates/bevy_winit/src/lib.rs#L602)
or when [Centered/Automatic by the code after the window is
created](https://github.com/bevyengine/bevy/blob/main/crates/bevy_winit/src/system.rs#L243),
am I missing some cases and do the codes I linked do that in all of
them?
- Are there any field in the `Window` component that can't be used to
modify the state of the window, only at creation?

# Objective
- Fix the AsBindGroup texture attribute visibility flag parsing
- This appears to have been caused by a syn crate update which then the
visibility code got updated
- Also I noticed that by default the vertex and fragment flags were on,
so visibility(compute) would actually make the texture visible to
vertex, fragment and compute shaders, I fixed this too
## Solution
- Update flag parsing to use MetaList.parse_nested_meta function, which
loads the flags into a Vec then loop through those flags
- Change initial visibility flags to use VisibilityFlags::default()
rather than VisibilityFlags::vertex_fragment()
# Objective
- Better consistency with `add_systems`.
- Deprecating `add_plugin` in favor of a more powerful `add_plugins`.
- Allow passing `Plugin` to `add_plugins`.
- Allow passing tuples to `add_plugins`.
## Solution
- `App::add_plugins` now takes an `impl Plugins` parameter.
- `App::add_plugin` is deprecated.
- `Plugins` is a new sealed trait that is only implemented for `Plugin`,
`PluginGroup` and tuples over `Plugins`.
- All examples, benchmarks and tests are changed to use `add_plugins`,
using tuples where appropriate.
---
## Changelog
### Changed
- `App::add_plugins` now accepts all types that implement `Plugins`,
which is implemented for:
- Types that implement `Plugin`.
- Types that implement `PluginGroup`.
- Tuples (up to 16 elements) over types that implement `Plugins`.
- Deprecated `App::add_plugin` in favor of `App::add_plugins`.
## Migration Guide
- Replace `app.add_plugin(plugin)` calls with `app.add_plugins(plugin)`.

# Objective
Fixes#6920
## Solution
From the issue discussion:
> From looking at the `AsBindGroup` derive macro implementation, the
fallback image's `TextureView` is used when the binding's
`Option<Handle<Image>>` is `None`. Because this relies on already having
a view that matches the desired binding dimensions, I think the solution
will require creating a separate `GpuImage` for each possible
`TextureViewDimension`.
---
## Changelog
Users can now rely on `FallbackImage` to work with a texture binding of
any dimension.
# Objective
Discovered that PointLight did not implement FromReflect. Adding
FromReflect where Reflect is used. I overreached and applied this rule
everywhere there was a Reflect without a FromReflect, except from where
the compiler wouldn't allow me.
Based from question: https://github.com/bevyengine/bevy/discussions/8774
## Solution
- Adding FromReflect where Reflect was already derived

# Objective
We can currently set `camera.target` to either an `Image` or `Window`.
For OpenXR & WebXR we need to be able to render to a `TextureView`.
This partially addresses #115 as with the addition we can create
internal and external xr crates.
## Solution
A `TextureView` item is added to the `RenderTarget` enum. It holds an id
which is looked up by a `ManualTextureViews` resource, much like how
`Assets<Image>` works.
I believe this approach was first used by @kcking in their [xr
fork](eb39afd51b/crates/bevy_render/src/camera/camera.rs (L322)).
The only change is that a `u32` is used to index the textures as
`FromReflect` does not support `uuid` and I don't know how to implement
that.
---
## Changelog
### Added
Render: Added `RenderTarget::TextureView` as a `camera.target` option,
enabling rendering directly to a `TextureView`.
## Migration Guide
References to the `RenderTarget` enum will need to handle the additional
field, ie in `match` statements.
---
## Comments
- The [wgpu
work](c039a74884)
done by @expenses allows us to create framebuffer texture views from
`wgpu v0.15, bevy 0.10`.
- I got the WebXR techniques from the [xr
fork](https://github.com/dekuraan/xr-bevy) by @dekuraan.
- I have tested this with a wip [external webxr
crate](018e22bb06/crates/bevy_webxr/src/bevy_utils/xr_render.rs (L50))

0.10.1 and 0.9):
I'm pretty confused because this bug is so easy to fix, it has been
around for so long, it is easy to encounter, and PRs touching this code
still didn't fix it: https://github.com/bevyengine/bevy/pull/7546 To the
point where I'm wondering if it's actually intended. If it is, please
explain why and this PR can be changed to "mention that in the doc".
## Solution
Fix the UV mapping on the Plane shape
Here is how it looks after the PR
## Test code
```rust
use bevy::{
prelude::*,
};
fn main () {
App::new()
.add_plugins(DefaultPlugins)
.add_startup_system(setup)
.run();
}
fn setup(
mut commands: Commands,
assets: ResMut<AssetServer>,
mut meshes: ResMut<Assets<Mesh>>,
mut materials: ResMut<Assets<StandardMaterial>>,
) {
commands.spawn(Camera3dBundle {
transform: Transform::from_xyz(0., 3., 0.).looking_at(Vec3::ZERO, Vec3::NEG_Z),
..default()
});
let mesh = meshes.add(Mesh::from(shape::Plane::default()));
let texture_image = assets.load("test.png");
let material = materials.add(StandardMaterial {
base_color_texture: Some(texture_image),
..default()
});
commands.spawn(PbrBundle {
mesh,
material,
..default()
});
}
```

# Objective
- When a window is closed, the associated camera keeps rendering even if
the RenderTarget isn't valid anymore.
- This is essentially just wasting a lot of performance.
## Solution
- Detect the window close event and disable any camera that used the
window has a RenderTarget.
## Notes
It's possible a similar thing could be done for camera that use an image
handle, but I would fix that in a separate PR.
# Objective
`NoFrustumCulling` doesn't implement `Reflect`, while nothing prevents
it from implementing it.
## Solution
Implement `Reflect` for it.
---
## Changelog
- Add `Reflect` derive to `NoFrustrumCulling`.
- Add `FromReflect` derive to `Visibility`.
Updates the requirements on

# Objective
- Introduce a stable alternative to
[`std::any::type_name`](https://doc.rust-lang.org/std/any/fn.type_name.html).
- Rewrite of #5805 with heavy inspiration in design.
- On the path to #5830.
- Part of solving #3327.
## Solution
- Add a `TypePath` trait for static stable type path/name information.
- Add a `TypePath` derive macro.
- Add a `impl_type_path` macro for implementing internal and foreign
types in `bevy_reflect`.
---
## Changelog
- Added `TypePath` trait.
- Added `DynamicTypePath` trait and `get_type_path` method to `Reflect`.
- Added a `TypePath` derive macro.
- Added a `bevy_reflect::impl_type_path` for implementing `TypePath` on
internal and foreign types in `bevy_reflect`.
- Changed `bevy_reflect::utility::(Non)GenericTypeInfoCell` to
`(Non)GenericTypedCell<T>` which allows us to be generic over both
`TypeInfo` and `TypePath`.
- `TypePath` is now a supertrait of `Asset`, `Material` and
`Material2d`.
- `impl_reflect_struct` needs a `#[type_path = "..."]` attribute to be
specified.
- `impl_reflect_value` needs to either specify path starting with a
double colon (`::core::option::Option`) or an `in my_crate::foo`
declaration.
- Added `bevy_reflect_derive::ReflectTypePath`.
- Most uses of `Ident` in `bevy_reflect_derive` changed to use
`ReflectTypePath`.
## Migration Guide
- Implementors of `Asset`, `Material` and `Material2d` now also need to
derive `TypePath`.
- Manual implementors of `Reflect` will need to implement the new
`get_type_path` method.
## Open Questions
- [x] ~This PR currently does not migrate any usages of
`std::any::type_name` to use `bevy_reflect::TypePath` to ease the review
process. Should it?~ Migration will be left to a follow-up PR.
- [ ] This PR adds a lot of `#[derive(TypePath)]` and `T: TypePath` to
satisfy new bounds, mostly when deriving `TypeUuid`. Should we make
`TypePath` a supertrait of `TypeUuid`? [Should we remove `TypeUuid` in
favour of
`TypePath`?](2afbd85532 (r961067892))
# Objective
- `apply_system_buffers` is an unhelpful name: it introduces a new
internal-only concept
- this is particularly rough for beginners as reasoning about how
commands work is a critical stumbling block
## Solution
- rename `apply_system_buffers` to the more descriptive `apply_deferred`
- rename related fields, arguments and methods in the internals fo
bevy_ecs for consistency
- update the docs
## Changelog
`apply_system_buffers` has been renamed to `apply_deferred`, to more
clearly communicate its intent and relation to `Deferred` system
parameters like `Commands`.
## Migration Guide
- `apply_system_buffers` has been renamed to `apply_deferred`
- the `apply_system_buffers` method on the `System` trait has been
renamed to `apply_deferred`
- the `is_apply_system_buffers` function has been replaced by
`is_apply_deferred`
- `Executor::set_apply_final_buffers` is now
`Executor::set_apply_final_deferred`
- `Schedule::apply_system_buffers` is now `Schedule::apply_deferred`

- Supress false positive `redundant_clone` lints.
- Supress inactionable `result_large_err` lint.
Most of the size(50 out of 68 bytes) is coming from

# Objective
- Make #8015 easier to review;
## Solution
- This commit contains changes not directly related to transmission
required by #8015, in easier-to-review, one-change-per-commit form.
---
## Changelog
### Fixed
- Clear motion vector prepass using `0.0` instead of `1.0`, to avoid TAA
artifacts on transparent objects against the background;
### Added
- The `E` mathematical constant is now available for use in shaders,
exposed under `bevy_pbr::utils`;
- A new `TAA` shader def is now available, for conditionally enabling
shader logic via `#ifdef` when TAA is enabled; (e.g. for jittering
texture samples)
- A new `FallbackImageZero` resource is introduced, for when a fallback
image filled with zeroes is required;
- A new `RenderPhase<I>::render_range()` method is introduced, for
render phases that need to render their items in multiple parceled out
“steps”;
### Changed
- The `MainTargetTextures` struct now holds both `Texture` and
`TextureViews` for the main textures;
- The fog shader functions under `bevy_pbr::fog` now take the a `Fog`
structure as their first argument, instead of relying on the global
`fog` uniform;
- The main textures can now be used as copy sources;
## Migration Guide
- `ViewTarget::main_texture()` and `ViewTarget::main_texture_other()`
now return `&Texture` instead of `&TextureView`. If you were relying on
these methods, replace your usage with
`ViewTarget::main_texture_view()`and
`ViewTarget::main_texture_other_view()`, respectively;
- `ViewTarget::sampled_main_texture()` now returns `Option<&Texture>`
instead of a `Option<&TextureView>`. If you were relying on this method,
replace your usage with `ViewTarget::sampled_main_texture_view()`;
- The `apply_fog()`, `linear_fog()`, `exponential_fog()`,
`exponential_squared_fog()` and `atmospheric_fog()` functions now take a
configurable `Fog` struct. If you were relying on them, update your
usage by adding the global `fog` uniform as their first argument;
# Objective
Fix#8604
## Solution
Use `.add_srgb_suffix()` when creating the screenshot texture.
Allow converting `Bgra8Unorm` images.
Only a two line change for the fix, the `screenshot.rs` changes are just
a bit of cleanup.
# Objective
Fix warnings:

## Solution
- Remove the mut keyword in those variables.
# Objective
- Update dependencies `ruzstd` and `basis-universal`
- Alternative to #5278 and #8133
## Solution
- Update the dependencies, fix the code
- Bevy now also depend on `syn@2` so it's not a blocker to update
`ruzstd` anymore
# Objective
Fix an out-of-date doc string.
The old doc string says "returns None if …" and "for a given
descriptor",
but this method neither takes an argument or returns an `Option`.
# Objective
Add support for the [Netpbm](https://en.wikipedia.org/wiki/Netpbm) image
formats, behind a `pnm` feature flag.
My personal use case for this was robotics applications, with `pgm`
being a popular format used in the field to represent world maps in
robots.
I chose the formats and feature name by checking the logic in
[image.rs](a35ed552fa/crates/bevy_render/src/texture/image.rs (L76))
## Solution
Quite straightforward, the `pnm` feature flag already exists in the
`image` crate so it's just creating and exposing a `pnm` feature flag in
the root `Cargo.toml` and forwarding it through `bevy_internal` and
`bevy_render` all the way to the `image` crate.
---
## Changelog
### Added
`pnm` feature to add support for `pam`, `pbm`, `pgm` and `ppm` image
formats.

# Objective
- Fixes#3531
## Solution
- Added an append wrapper to BufferVec based on the function signature
for vec.append()
---
First PR to Bevy. I didn't see any tests for other BufferVec methods
(could have missed them) and currently this method is not used anywhere
in the project. Let me know if there are tests to add or if I should
find somewhere to use append so it is not dead code. The issue mentions
implementing `truncate` and `extend` which were already implemented and
merged
[here](https://github.com/bevyengine/bevy/pull/6833/files#diff-c8fb332382379e383f1811e30c31991b1e0feb38ca436c357971755368012ced)
# Objective
- When writing render nodes that need a view, you always need to define
a `Query` on the associated view and make sure to update it manually and
query it manually. This is verbose and error prone.
## Solution
- Introduce a new `ViewNode` trait and `ViewNodeRunner` `Node` that will
take care of managing the associated view query automatically.
- The trait is currently a passthrough of the `Node` trait. So it still
has the update/run with all the same data passed in.
- The `ViewNodeRunner` is the actual node that is added to the render
graph and it contains the custom node. This is necessary because it's
the one that takes care of updating the node.
---
## Changelog
- Add `ViewNode`
- Add `ViewNodeRunner`
## Notes
Currently, this only handles the view query, but it could probably have
a ReadOnlySystemState that would also simplify querying all the readonly
resources that most render nodes currently query manually. The issue is
that I don't know how to do that without a `&mut self`.
At first, I tried making this a default feature of all `Node`, but I
kept hitting errors related to traits and generics and stuff I'm not
super comfortable with. This implementations is much simpler and keeps
the default Node behaviour so isn't a breaking change
## Reviewer Notes
The PR looks quite big, but the core of the PR is the changes in
`render_graph/node.rs`. Every other change is simply updating existing
nodes to use this new feature.
## Open questions
~~- Naming is not final, I'm opened to anything. I named it
ViewQueryNode because it's a node with a managed Query on a View.~~
~~- What to do when the query fails? All nodes using this pattern
currently just `return Ok(())` when it fails, so I chose that, but
should it be more flexible?~~
~~- Is the ViewQueryFilter actually necessary? All view queries run on
the entity that is already guaranteed to be a view. Filtering won't do
much, but maybe someone wants to control an effect with the presence of
a component instead of a flag.~~
~~- What to do with Nodes that are empty struct? Implementing
`FromWorld` is pretty verbose but not implementing it means there's 2
ways to create a `ViewNodeRunner` which seems less ideal. This is an
issue now because most node simply existed to hold the query, but now
that they don't hold the query state we are left with a bunch of empty
structs.~~
- Should we have a `RenderGraphApp::add_render_graph_view_node()`, this
isn't necessary, but it could make the code a bit shorter.

# Objective
- Support WebGPU
- alternative to #5027 that doesn't need any async / await
- fixes#8315
- Surprise fix#7318
## Solution
### For async renderer initialisation
- Update the plugin lifecycle:
- app builds the plugin
- calls `plugin.build`
- registers the plugin
- app starts the event loop
- event loop waits for `ready` of all registered plugins in the same
order
- returns `true` by default
- then call all `finish` then all `cleanup` in the same order as
registered
- then execute the schedule
In the case of the renderer, to avoid anything async:
- building the renderer plugin creates a detached task that will send
back the initialised renderer through a mutex in a resource
- `ready` will wait for the renderer to be present in the resource
- `finish` will take that renderer and place it in the expected
resources by other plugins
- other plugins (that expect the renderer to be available) `finish` are
called and they are able to set up their pipelines
- `cleanup` is called, only custom one is still for pipeline rendering
### For WebGPU support
- update the `build-wasm-example` script to support passing `--api
webgpu` that will build the example with WebGPU support
- feature for webgl2 was always enabled when building for wasm. it's now
in the default feature list and enabled on all platforms, so check for
this feature must also check that the target_arch is `wasm32`
---
## Migration Guide
- `Plugin::setup` has been renamed `Plugin::cleanup`
- `Plugin::finish` has been added, and plugins adding pipelines should
do it in this function instead of `Plugin::build`
```rust
// Before
impl Plugin for MyPlugin {
fn build(&self, app: &mut App) {
app.insert_resource::<MyResource>
.add_systems(Update, my_system);
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<RenderResourceNeedingDevice>()
.init_resource::<OtherRenderResource>();
}
}
// After
impl Plugin for MyPlugin {
fn build(&self, app: &mut App) {
app.insert_resource::<MyResource>
.add_systems(Update, my_system);
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<OtherRenderResource>();
}
fn finish(&self, app: &mut App) {
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<RenderResourceNeedingDevice>();
}
}
```
# Objective
- I want to take screenshots of examples in CI to help with validation
of changes
## Solution
- Can override how much time is updated per frame
- Can specify on which frame to take a screenshots
- Save screenshots in CI
I reused the `TimeUpdateStrategy::ManualDuration` to be able to set the
time update strategy to a fixed duration every frame. Its previous
meaning didn't make much sense to me. This change makes it possible to
have screenshots that are exactly the same across runs.
If this gets merged, I'll add visual comparison of screenshots between
runs to ensure nothing gets broken
## Migration Guide
* `TimeUpdateStrategy::ManualDuration` meaning has changed. Instead of
setting time to `Instant::now()` plus the given duration, it sets time
to last update plus the given duration.
# Objective
- Handle dangling entity references inside scenes
- Handle references to entities with generation > 0 inside scenes
- Fix a latent bug in `Parent`'s `MapEntities` implementation, which
would, if the parent was outside the scene, cause the scene to be loaded
into the new world with a parent reference potentially pointing to some
random entity in that new world.
- Fixes#4793 and addresses #7235
## Solution
- DynamicScenes now identify entities with a `Entity` instead of a u32,
therefore including generation
- `World` exposes a new `reserve_generations` function that despawns an
entity and advances its generation by some extra amount.
- `MapEntities` implementations have a new `get_or_reserve` function
available that will always return an `Entity`, establishing a new
mapping to a dead entity when the entity they are called with is not in
the `EntityMap`. Subsequent calls with that same `Entity` will return
the same newly created dead entity reference, preserving equality
semantics.
- As a result, after loading a scene containing references to dead
entities (or entities otherwise outside the scene), those references
will all point to different generations on a single entity id in the new
world.
---
## Changelog
### Changed
- In serialized scenes, entities are now identified by a u64 instead of
a u32.
- In serialized scenes, components with entity references now have those
references serialize as u64s instead of structs.
### Fixed
- Scenes containing components with entity references will now
deserialize and add to a world reliably.
## Migration Guide
- `MapEntities` implementations must change from a `&EntityMap`
parameter to a `&mut EntityMapper` parameter and can no longer return a
`Result`. Finally, they should switch from calling `EntityMap::get` to
calling `EntityMapper::get_or_reserve`.
