# Objective
Bevy prefers `mod.rs` inside `module_name` files over `module_name.rs`
collocated with `module_name`. In `bevy_render`, it seems the `window`
modules didn't follow this convention
## Solution
- Follow the `mod.rs` convention.
# Objective
- Fixes#9324
- Audio sinks used to have a custom drop implementation to detach the
sinks because it was not required to keep a reference to it
- With the new audio api, a reference is kept as a component of an
entity
## Solution
- Remove that custom drop implementation, and the option wrapping that
was required for it.
# Objective
In the `game_menu` example:
```rust
let button_icon_style = Style {
width: Val::Px(30.0),
// This takes the icons out of the flexbox flow, to be positioned exactly
position_type: PositionType::Absolute,
// The icon will be close to the left border of the button
left: Val::Px(10.0),
right: Val::Auto,
..default()
};
```
The default value for `right` is `Val::Auto` so that line is unnecessary
and can be removed.
# Objective
Just like
[`set_if_neq`](https://docs.rs/bevy_ecs/latest/bevy_ecs/change_detection/trait.DetectChangesMut.html#method.set_if_neq),
being able to express the "I don't want to unnecessarily trigger the
change detection" but with the ability to handle the previous value if
change occurs.
## Solution
Add `replace_if_neq` to `DetectChangesMut`.
---
## Changelog
- Added `DetectChangesMut::replace_if_neq`: like `set_if_neq` change the
value only if the new value if different from the current one, but
return the previous value if the change occurs.
# Objective
I found it very difficult to understand how bevy tasks work, and I
concluded that the documentation should be improved for beginners like
me.
## Solution
These changes to the documentation were written from my beginner's
perspective after
some extremely helpful explanations by nil on Discord.
I am not familiar enough with rustdoc yet; when looking at the source, I
found the documentation at the very top of `usages.rs` helpful, but I
don't know where they are rendered. They should probably be linked to
from the main `bevy_tasks` README.

# Objective
In `bevy_sprite`, the `Anchor` type is not `Copy`. It makes interacting
with it more difficult than necessary.
## Solution
Derive `Copy` on it. The rust API guidelines are that you should derive
`Copy` when possible.
<https://rust-lang.github.io/api-guidelines/interoperability.html#types-eagerly-implement-common-traits-c-common-traits>
Regardless, `Anchor` is a very small `enum` which warrants `Copy`.

## Changelog
- In `bevy_sprite` `Anchor` is now `Copy`.

Add a `RunSystem` extension trait to allow for immediate execution of
systems on a `World` for debugging and/or testing purposes.
# Objective
Fixes#6184
Initially, I made this CL as `ApplyCommands`. After a discussion with
@cart , we decided a more generic implementation would be better to
support all systems. This is the new revised CL. Sorry for the long
delay! 😅
This CL allows users to do this:
```rust
use bevy::prelude::*;
use bevy::ecs::system::RunSystem;
struct T(usize);
impl Resource for T {}
fn system(In(n): In<usize>, mut commands: Commands) -> usize {
commands.insert_resource(T(n));
n + 1
}
let mut world = World::default();
let n = world.run_system_with(1, system);
assert_eq!(n, 2);
assert_eq!(world.resource::<T>().0, 1);
```
## Solution
This is implemented as a trait extension and not included in any
preludes to ensure it's being used consciously.
Internally, it just initializes and runs a systems, and applies any
deferred parameters all "in place".
The trait has 2 functions (one of which calls the other by default):
- `run_system_with` is the general implementation, which allows user to
pass system input parameters
- `run_system` is the ergonomic wrapper for systems with no input
parameter (to avoid having the user pass `()` as input).
~~Additionally, this trait is also implemented for `&mut App`. I added
this mainly for ergonomics (`app.run_system` vs.
`app.world.run_system`).~~ (Removed based on feedback)

# Objective
Add possibility to use the glam's swizzles traits without having to
manually import them.
```diff
use bevy::prelude::*;
- use bevy::math::Vec3Swizzles;
fn foo(x: Vec3) {
let y: Vec2 = x.xy();
}
```
## Solution
Add the swizzles traits to bevy's prelude.
---
## Changelog
- `Vec2Swizzles`, `Vec3Swizzles` and `Vec4Swizzles` are now part of the
prelude.
# Objective
- I want to run the post_processing example in a new project, but I
can't because it uses bevy internal imports.
## Solution
- Change the bevy_internal imports to their respective bevy crates
imports
# Objective
Fixes#9094
## Solution
Takes a bit from
[this](https://github.com/bevyengine/bevy/issues/9094#issuecomment-1629333851)
comment as well as a
[comment](https://discord.com/channels/691052431525675048/1002362493634629796/1128024873260810271)
from @soqb.
This allows users to opt-out of the `TypePath` implementation that is
automatically generated by the `Reflect` derive macro, allowing custom
`TypePath` implementations.
```rust
#[derive(Reflect)]
#[reflect(type_path = false)]
struct Foo<T> {
#[reflect(ignore)]
_marker: PhantomData<T>,
}
struct NotTypePath;
impl<T: 'static> TypePath for Foo<T> {
fn type_path() -> &'static str {
std::any::type_name::<Self>()
}
fn short_type_path() -> &'static str {
static CELL: GenericTypePathCell = GenericTypePathCell::new();
CELL.get_or_insert::<Self, _>(|| {
bevy_utils::get_short_name(std::any::type_name::<Self>())
})
}
fn crate_name() -> Option<&'static str> {
Some("my_crate")
}
fn module_path() -> Option<&'static str> {
Some("my_crate::foo")
}
fn type_ident() -> Option<&'static str> {
Some("Foo")
}
}
// Can use `TypePath`
let _ = <Foo<NotTypePath> as TypePath>::type_path();
// Can register the type
let mut registry = TypeRegistry::default();
registry.register::<Foo<NotTypePath>>();
```
#### Type Path Stability
The stability of type paths mainly come into play during serialization.
If a type is moved between builds, an unstable type path may become
invalid.
Users that opt-out of `TypePath` and rely on something like
`std::any::type_name` as in the example above, should be aware that this
solution removes the stability guarantees. Deserialization thus expects
that type to never move. If it does, then the serialized type paths will
need to be updated accordingly.
If a user depends on stability, they will need to implement that
stability logic manually (probably by looking at the expanded output of
a typical `Reflect`/`TypePath` derive). This could be difficult for type
parameters that don't/can't implement `TypePath`, and will need to make
heavy use of string parsing and manipulation to achieve the same effect
(alternatively, they can choose to simply exclude any type parameter
that doesn't implement `TypePath`).
---
## Changelog
- Added the `#[reflect(type_path = false)]` attribute to opt out of the
`TypePath` impl when deriving `Reflect`

# Objective
Update a camera's frustum only when needed.
- Maybe a performance gain from not having to compute frusta when not
needed, at the cost of change detection (?)
- Making "fighting" with `update_frusta` less tedious, see
https://github.com/bevyengine/bevy/issues/9077 and
https://discord.com/channels/691052431525675048/743663924229963868/1127566087966433322
## Solution
Add change detection filter for `GlobalTransform` or `T:
CameraProjection` in `update_frusta`, since those are the cases when the
frustum needs to be updated.
## Note
I don't think a migration guide and changelog are needed, but I'm not
100% sure, I could put something like "if you're fighting against
`update_frusta`, you can do it only when there is a change to
`GlobalTransform` or `CameraProjection` now", what do you think? It's
not really a breaking change with a normal use case.
# Objective
In the shader prepass example, changing to the motion vector output
hides the text, because both it and the background are rendererd black.
Seems to have been caused by this commit?
71cf35ce42
## Solution
Make the text white on all outputs.
naga and wgpu should polyfill WGSL instance_index functionality where it
is not available in GLSL. Until that is done, we can work around it in
bevy using a push constant which is converted to a uniform by naga and
wgpu.
# Objective
- Fixes#9375
## Solution
- Use a push constant to pass in the base instance to the shader on
WebGL2 so that base instance + gl_InstanceID is used to correctly
represent the instance index.
## TODO
- [ ] Benchmark vs per-object dynamic offset MeshUniform as this will
now push a uniform value per-draw as well as update the dynamic offset
per-batch.
- [x] Test on DX12 AMD/NVIDIA to check that this PR does not regress any
problems that were observed there. (@Elabajaba @robtfm were testing that
last time - help appreciated. <3 )
---
## Changelog
- Added: `bevy_render::instance_index` shader import which includes a
workaround for the lack of a WGSL `instance_index` polyfill for WebGL2
in naga and wgpu for the time being. It uses a push_constant which gets
converted to a plain uniform by naga and wgpu.
## Migration Guide
Shader code before:
```
struct Vertex {
@builtin(instance_index) instance_index: u32,
...
}
@vertex
fn vertex(vertex_no_morph: Vertex) -> VertexOutput {
...
var model = mesh[vertex_no_morph.instance_index].model;
```
After:
```
#import bevy_render::instance_index
struct Vertex {
@builtin(instance_index) instance_index: u32,
...
}
@vertex
fn vertex(vertex_no_morph: Vertex) -> VertexOutput {
...
var model = mesh[bevy_render::instance_index::get_instance_index(vertex_no_morph.instance_index)].model;
```
# Objective
Provide a slightly better message when a contributor needs to update the
generated example readme file for [any number of
reasons](https://github.com/bevyengine/bevy/pull/9372#discussion_r1285876202)
but hasn't added any examples.
This recently happened here:
https://github.com/bevyengine/bevy/pull/9370#issuecomment-1666776092
The contributor modified the readme template and is being told that they
added an example.
## Solution
The advice given is still correct. Just change the message so that it's
not accusing the contributor of adding an example.
It may be possible to instead add more specific messages instead if
someone is motivated to do that.

# Objective
The default for `ContentSize` should have the `measure_func` field set
to `None`, instead of a fixed size of zero. This means that until a
measure func is set the size of the UI node will be determined by its
`Style` constraints. This is preferable as it allows users to specify
the space the Node should take up in the layout while waiting for
content to load.
## Solution
Derive `Default` for `ContentSize`.
The PR also adds a `fixed_size` helper function to make it a bit easier
to access the old behaviour.
## Changelog
* Derived `Default` for `ContentSize`
* Added a `fixed_size` helper function to `ContentSize` that creates a
new `ContentSize` with a `MeasureFunc` that always returns the same
value, regardless of layout constraints.
## Migration Guide
The default for `ContentSize` now sets its `measure_func` to `None`,
instead of a fixed size measure that returns `Vec2::ZERO`.
The helper function `fixed_size` can be called with
`ContentSize::fixed_size(Vec2::ZERO)` to get the previous behaviour.
# Objective
It seems the behavior of field attributes was accidentally broken at
some point. Take the following code:
```rust
#[derive(Reflect)]
struct Foo {
#[reflect(ignore, default)]
value: usize
}
```
The above code should simply mark `value` as ignored and specify a
default behavior. However, what this actually does is discard both.
That's especially a problem when we don't want the field to be be given
a `Reflect` or `FromReflect` bound (which is why we ignore it in the
first place).
This only happens when the attributes are combined into one. The
following code works properly:
```rust
#[derive(Reflect)]
struct Foo {
#[reflect(ignore)]
#[reflect(default)]
value: usize
}
```
## Solution
Cleaned up the field attribute parsing logic to support combined field
attributes.
---
## Changelog
- Fixed a bug where `Reflect` derive attributes on fields are not able
to be combined into a single attribute
# Objective
- I forgot to update the example after the `ViewNodeRunner` was merged.
It was even partially mentioned in one of the comments.
## Solution
- Use the `ViewNodeRunner` in the post_processing example
- I also broke up a few lines that were a bit long

# Objective
- Follow up to #8887
- The parsing code in `bevy_reflect/src/path/mod.rs` could also do with
some cleanup
## Solution
- Create the `parse.rs` module, move all parsing code to this module
- The parsing errors also now keep track of the whole parsed string, and
are much more fine-grained
### Detailed changes
- Move `PathParser` to `parse.rs` submodule
- Rename `token_to_access` to `access_following` (yep, goes from 132
lines to 16)
- Move parsing tests into the `parse.rs` file
# Objective
The doc comment for `text_system` is not quite correct. It implies that
a new `TextLayoutInfo` is generated on changes to `Text` and `Style`.
While changes to those components might indirectly trigger a
regeneration of the text layout, `text_system` itself only queries for
changes to `Node`
Also added details to `measure_text_system`'s doc comments explaining
how it reacts to changes.

# Objective
- `bevy_tasks` emits warnings under certain conditions
When I run `cargo clippy -p bevy_tasks` the warning doesn't show up,
while if I run it with `cargo clippy -p bevy_asset` the warning shows
up.
## Solution
- Fix the warnings.
## Longer term solution
We should probably fix CI so that those warnings do not slip through.
But that's not the goal of this PR.
# Objective
The `post_processing` example is currently broken when run with webgl2.
```
cargo run --example post_processing --target=wasm32-unknown-unknown

```
I bisected the breakage to c7eaedd6a1.
## Solution
Add padding when using webgl2
# Objective
This doc comment for the `set` method of `ContentSize`:

# Solution
Replace it.
# Objective
When an `AudioSink` is removed from an entity, the audio player will
automatically start any `AudioSource` still attached, which normally is

Long story short, the default behavior is restarting the audio, and this
commit documents that.

## Changelog
Fixed documentation on `AudioSink` to clarify removal behavior.
# Objective
- Some examples crash in CI because of needing too many resources for

- `bloom_3d`: reduce the number of spheres
- `pbr`: use simpler spheres and reuse the mesh
- `tonemapping`: use simpler spheres and reuse the mesh
- `shadow_biases`: reduce the number of spheres

## Solution
Inside `ScheduleGraph::build_schedule()` the variable `node_count =
self.systems.len() + self.system_sets.len()` is used to calculate the
indices for the `reachable` bitset derived from `self.hierarchy.graph`.
However, the number of nodes inside `self.hierarchy.graph` does not
always correspond to `self.systems.len() + self.system_sets.len()` when
`ambiguous_with` is used, because an ambiguous set is added to
`system_sets` (because we need an `NodeId` for the ambiguity graph)
without adding a node to `self.hierarchy`.
In this PR, we rename `node_count` to the more descriptive name
`hg_node_count` and set it to `self.hierarchy.graph.node_count()`.

## Solution
disable `multi-threaded` default feature
## Migration Guide
The `multi-threaded` feature in `bevy_ecs` and `bevy_tasks` is no longer
enabled by default. However, this remains a default feature for the
umbrella `bevy` crate. If you depend on `bevy_ecs` or `bevy_tasks`
directly, you should consider enabling this to allow systems to run in
parallel.
Fixes#5856. Fixes#8080. Fixes#9040.
# Objective
We need to limit the update rate of games whose windows are not visible
(minimized or completely occluded). Compositors typically ignore the
VSync settings of windows that aren't visible. That, combined with the
lack of rendering work, results in a scenario where an app becomes
completely CPU-bound and starts updating without limit.
There are currently three update modes.
- `Continuous` updates an app as often as possible.
- `Reactive` updates when new window or device events have appeared, a
timer expires, or a redraw is requested.
- `ReactiveLowPower` is the same as `Reactive` except it ignores device
events (e.g. general mouse movement).
The problem is that the default "game" settings are set to `Contiuous`
even when no windows are visible.
### More Context
- https://github.com/libsdl-org/SDL/issues/1871
- https://github.com/glfw/glfw/issues/680
- https://github.com/godotengine/godot/issues/19741
- https://github.com/godotengine/godot/issues/64708
## Solution
Change the default "unfocused" `UpdateMode` for games to
`ReactiveLowPower` just like desktop apps. This way, even when the
window is occluded, the app still updates at a sensible rate or if
something about the window changes. I chose 20Hz arbitrarily.
# Objective
The `lifetimeless` module has been a source of confusion for bevy users
for a while now.
## Solution
Add a couple paragraph explaining that, yes, you can use one of the type
alias safely, without ever leaking any memory.
Redo of #7590 since I messed up my branch.
# Objective
- Revise docs.
- Refactor event loop code a little bit to make it easier to follow.
## Solution
- Do the above.

Remove the `With<Parent>` query filter from the `parent_node_query`
parameter of the `bevy_ui::render::extract_uinode_borders` function.

# Objective
- Fixes#9138
## Solution
- Calling `Camera2dBundle::default()` will now result in a
`Camera2dBundle` with `Vec3::ZERO` transform, `far` value of `1000.` and
`near` value of `-1000.`.
- This will enable the rendering of 2d entities in negative z space by
default.
- I did not modify `new_with_far` as moving the camera to `Vec3::ZERO`
in that function will cause entities in the positive z space to become
hidden without further changes. And the further changes cannot be
applied without it being a breaking change.

but still)
The first time I used gizmos I didn't understand how they work and was

# Objective
This PR continues https://github.com/bevyengine/bevy/pull/8885
It aims to improve the `Mesh` documentation in the following ways:
- Put everything at the "top level" instead of the "impl".
- Explain better what is a Mesh, how it can be created, and that it can
be edited.
- Explain it can be used with a `Material`, and mention
`StandardMaterial`, `PbrBundle`, `ColorMaterial`, and
`ColorMesh2dBundle` since those cover most cases
- Mention the glTF/Bevy vocabulary discrepancy for "Mesh"
- Add an image for the example
- Various nitpicky modifications
## Note
- The image I added is 90.3ko which I think is small enough?
- Since rustdoc doesn't allow cross-reference not in dependencies of a
subcrate [yet](https://github.com/rust-lang/rust/issues/74481), I have a
lot of backtick references that are not links :(
- Since rustdoc doesn't allow linking to code in the crate (?) I put
link to github directly.
- Since rustdoc doesn't allow embed images in doc
[yet](https://github.com/rust-lang/rust/issues/32104), maybe
[soon](https://github.com/rust-lang/rfcs/pull/3397), I had to put only a
link to the image. I don't think it's worth adding
[embed_doc_image](https://docs.rs/embed-doc-image/latest/embed_doc_image/)
as a dependency for this.
# Objective
- Fix shader_material_glsl example
## Solution
- Expose the `PER_OBJECT_BUFFER_BATCH_SIZE` shader def through the
default `MeshPipeline` specialization.
- Make use of it in the `custom_material.vert` shader to access the mesh
binding.
---
## Changelog
- Added: Exposed the `PER_OBJECT_BUFFER_BATCH_SIZE` shader def through
the default `MeshPipeline` specialization to use in custom shaders not
using bevy_pbr::mesh_bindings that still want to use the mesh binding in
some way.
# Objective
- The `path` module was getting fairly large.
- The code in `AccessRef::read_element` and mut equivalent was very
complex and difficult to understand.
- The `ReflectPathError` had a lot of variants, and was difficult to
read.
## Solution
- Split the file in two, `access` now has its own module
- Rewrite the `read_element` methods, they were ~200 lines long, they
are now ~70 lines long — I didn't change any of the logic. It's really
just the same code, but error handling is separated.
- Split the `ReflectPathError` error
- Merge `AccessRef` and `Access`
- A few other changes that aim to reduce code complexity
### Fully detailed change list
- `Display` impl of `ParsedPath` now includes prefix dots — this allows
simplifying its implementation, and IMO `.path.to.field` is a better way
to express a "path" than `path.to.field` which could suggest we are
reading the `to` field of a variable named `path`
- Add a test to check that dot prefixes and other are correctly parsed —
Until now, no test contained a prefixing dot
- Merge `Access` and `AccessRef`, using a `Cow<'a, str>`. Generated code
seems to agree with this decision (`ParsedPath::parse` sheds 5% of
instructions)
- Remove `Access::as_ref` since there is no such thing as an `AccessRef`
anymore.
- Rename `AccessRef::to_owned` into `AccessRef::into_owned()` since it
takes ownership of `self` now.
- Add a `parse_static` that doesn't allocate new strings for named
fields!
- Add a section about path reflection in the `bevy_reflect` crate root
doc — I saw a few people that weren't aware of path reflection, so I
thought it was pertinent to add it to the root doc
- a lot of nits
- rename `index` to `offset` when it refers to offset in the path string
— There is no more confusion with the other kind of indices in this
context, also it's a common naming convention for parsing.
- Make a dedicated enum for parsing errors
- rename the `read_element` methods to `element` — shorter, but also
`read_element_mut` was a fairly poor name
- The error values now not only contain the expected type but also the
actual type.
- Remove lifetimes that could be inferred from the `GetPath` trait
methods.
---
## Change log
- Added the `ParsedPath::parse_static` method, avoids allocating when
parsing `&'static str`.
## Migration Guide
If you were matching on the `Err(ReflectPathError)` value returned by
`GetPath` and `ParsedPath` methods, now only the parse-related errors
and the offset are publicly accessible. You can always use the
`fmt::Display` to get a clear error message, but if you need
programmatic access to the error types, please open an issue.

- attempt to clarify with better docstrings the default behaviour of
WindowPlugin and the component type it accepts.
# Objective
- I'm new to Rust and Bevy, I got a bit confused about how to customise
some window parameters (title, height, width etc) and while the docs do
show the struct code for that field `Option<Window>` I was a bit of a
doofus and skipped that to read the docstring entry for `primary_window`
and then the `Window` component directly which aren't linked together.
This is a minor improvement which I think will help in-case others, like
me, have a doofus moment.
