# Objective
There are a lot of doctests that are `ignore`d for no documented reason.
And that should be fixed.
## Solution
I searched the bevy repo with the regex ` ```[a-z,]*ignore ` in order to
find all `ignore`d doctests. For each one of the `ignore`d doctests, I
did the following steps:
1. Attempt to remove the `ignored` attribute while still passing the
test. I did this by adding hidden dummy structs and imports.
2. If step 1 doesn't work, attempt to replace the `ignored` attribute
with the `no_run` attribute while still passing the test.
3. If step 2 doesn't work, keep the `ignored` attribute but add
documentation for why the `ignored` attribute was added.

# Objective
- Custom render passes, or future passes in the engine (such as
https://github.com/bevyengine/bevy/pull/10164) need a better way to know
and indicate to the core passes whether the view color/depth/prepass
attachments have been cleared or not yet this frame, to know if they
should clear it themselves or load it.
## Solution
- For all render targets (depth textures, shadow textures, prepass
textures, main textures) use an atomic bool to track whether or not each
texture has been cleared this frame. Abstracted away in the new
ColorAttachment and DepthAttachment wrappers.
---
## Changelog
- Changed `ViewTarget::get_color_attachment()`, removed arguments.
- Changed `ViewTarget::get_unsampled_color_attachment()`, removed
arguments.
- Removed `Camera3d::clear_color`.
- Removed `Camera2d::clear_color`.
- Added `Camera::clear_color`.
- Added `ExtractedCamera::clear_color`.
- Added `ColorAttachment` and `DepthAttachment` wrappers.
- Moved `ClearColor` and `ClearColorConfig` from
`bevy::core_pipeline::clear_color` to `bevy::render::camera`.
- Core render passes now track when a texture is first bound as an
attachment in order to decide whether to clear or load it.
## Migration Guide
- Remove arguments to `ViewTarget::get_color_attachment()` and
`ViewTarget::get_unsampled_color_attachment()`.
- Configure clear color on `Camera` instead of on `Camera3d` and
`Camera2d`.
- Moved `ClearColor` and `ClearColorConfig` from
`bevy::core_pipeline::clear_color` to `bevy::render::camera`.
- `ViewDepthTexture` must now be created via the `new()` method

# Objective
Provide an example of how to achieve pixel-perfect "grid snapping" in 2D
via rendering to a texture. This is a common use case in retro pixel art
game development.
## Solution
Render sprites to a canvas via a Camera, then use another (scaled up)
Camera to render the resulting canvas to the screen. This example is
based on the `3d/render_to_texture.rs` example. Furthermore, this
example demonstrates mixing retro-style graphics with high-resolution
graphics, as well as pixel-snapped rendering of a
`MaterialMesh2dBundle`.
# Objective
- Make the implementation order consistent between all sources to fit
the order in the trait.
## Solution
- Change the implementation order.
Improves #11052
# Changelog
- Remove `Window::fit_canvas_to_parent`, as its resizing on wasm now
respects its CSS configuration.
## Migration Guide
- Remove uses of `Window::fit_canvas_to_parent` in favor of CSS
properties, for example:
```css
canvas {
width: 100%;
height: 100%;
}
```
# Objective
Fix#10731.
## Solution
Rename `App::add_state<T>(&mut self)` to `init_state`, and add
`App::insert_state<T>(&mut self, state: T)`. I decided on these names
because they are more similar to `init_resource` and `insert_resource`.
I also removed the `States` trait's requirement for `Default`. Instead,
`init_state` requires `FromWorld`.
---
## Changelog
- Renamed `App::add_state` to `init_state`.
- Added `App::insert_state`.
- Removed the `States` trait's requirement for `Default`.
## Migration Guide
- Renamed `App::add_state` to `init_state`.
# Objective
- Update winit dependency to 0.29
## Changelog
### KeyCode changes
- Removed `ScanCode`, as it was [replaced by
KeyCode](https://github.com/rust-windowing/winit/blob/master/CHANGELOG.md#0292).
- `ReceivedCharacter.char` is now a `SmolStr`, [relevant
doc](https://docs.rs/winit/latest/winit/event/struct.KeyEvent.html#structfield.text).
- Changed most `KeyCode` values, and added more.
KeyCode has changed meaning. With this PR, it refers to physical
position on keyboard rather than the printed letter on keyboard keys.
In practice this means:
- On QWERTY keyboard layouts, nothing changes
- On any other keyboard layout, `KeyCode` no longer reflects the label
on key.
- This is "good". In bevy 0.12, when you used WASD for movement, users
with non-QWERTY keyboards couldn't play your game! This was especially
bad for non-latin keyboards. Now, WASD represents the physical keys. A
French player will press the ZQSD keys, which are near each other,
Kyrgyz players will use "Цфыв".
- This is "bad" as well. You can't know in advance what the label of the
key for input is. Your UI says "press WASD to move", even if in reality,
they should be pressing "ZQSD" or "Цфыв". You also no longer can use
`KeyCode` for text inputs. In any case, it was a pretty bad API for text
input. You should use `ReceivedCharacter` now instead.
### Other changes
- Use `web-time` rather than `instant` crate.
(https://github.com/rust-windowing/winit/pull/2836)
- winit did split `run_return` in `run_onDemand` and `pump_events`, I
did the same change in bevy_winit and used `pump_events`.
- Removed `return_from_run` from `WinitSettings` as `winit::run` now
returns on supported platforms.
- I left the example "return_after_run" as I think it's still useful.
- This winit change is done partly to allow to create a new window after
quitting all windows: https://github.com/emilk/egui/issues/1918 ; this
PR doesn't address.
- added `width` and `height` properties in the `canvas` from wasm
example
(https://github.com/bevyengine/bevy/pull/10702#discussion_r1420567168)
## Known regressions (important follow ups?)
- Provide an API for reacting when a specific key from current layout
was released.
- possible solutions: use winit::Key from winit::KeyEvent ; mapping
between KeyCode and Key ; or .
- We don't receive characters through alt+numpad (e.g. alt + 151 = "ù")
anymore ; reproduced on winit example "ime". maybe related to
https://github.com/rust-windowing/winit/issues/2945
- (windows) Window content doesn't refresh at all when resizing. By
reading https://github.com/rust-windowing/winit/issues/2900 ; I suspect
we should just fire a `window.request_redraw();` from `AboutToWait`, and
handle actual redrawing within `RedrawRequested`. I'm not sure how to
move all that code so I'd appreciate it to be a follow up.
- (windows) unreleased winit fix for using set_control_flow in
AboutToWait https://github.com/rust-windowing/winit/issues/3215 ; ⚠️ I'm
not sure what the implications are, but that feels bad 🤔
## Follow up
I'd like to avoid bloating this PR, here are a few follow up tasks
worthy of a separate PR, or new issue to track them once this PR is
closed, as they would either complicate reviews, or at risk of being
controversial:
- remove CanvasParentResizePlugin
(https://github.com/bevyengine/bevy/pull/10702#discussion_r1417068856)
- avoid mentionning explicitly winit in docs from bevy_window ?
- NamedKey integration on bevy_input:
https://github.com/rust-windowing/winit/pull/3143 introduced a new
NamedKey variant. I implemented it only on the converters but we'd
benefit making the same changes to bevy_input.
- Add more info in KeyboardInput
https://github.com/bevyengine/bevy/pull/10702#pullrequestreview-1748336313
- https://github.com/bevyengine/bevy/pull/9905 added a workaround on a
bug allegedly fixed by winit 0.29. We should check if it's still
necessary.
- update to raw_window_handle 0.6
- blocked by wgpu
- Rename `KeyCode` to `PhysicalKeyCode`
https://github.com/bevyengine/bevy/pull/10702#discussion_r1404595015
- remove `instant` dependency, [replaced
by](https://github.com/rust-windowing/winit/pull/2836) `web_time`), we'd
need to update to :
- fastrand >= 2.0
- [`async-executor`](https://github.com/smol-rs/async-executor) >= 1.7
- [`futures-lite`](https://github.com/smol-rs/futures-lite) >= 2.0
- Verify license, see
[discussion](https://github.com/bevyengine/bevy/pull/8745#discussion_r1402439800)
- we might be missing a short notice or description of changes made
- Consider using https://github.com/rust-windowing/cursor-icon directly
rather than vendoring it in bevy.
- investigate [this
unwrap](https://github.com/bevyengine/bevy/pull/8745#discussion_r1387044986)
(`winit_window.canvas().unwrap();`)
- Use more good things about winit's update
- https://github.com/bevyengine/bevy/pull/10689#issuecomment-1823560428
## Migration Guide
This PR should have one.
# Objective
- Expand the texture_atlas example with padding and show how it can
resolve sprite bleeding for different types of sampling.
- Fixes#9522
## Solution
Updated the texture_atlas example by adding 4 different texture atlases:
1. linear, no padding
2. linear, padding
3. nearest neighbor, no padding
4. nearest neighbor, padding
Now renders one padded and one unpadded texture atlas, and the same
upscaled sprite from each of the new texture atlases. See the screenshot
below (taken on 1080p monitor).
**From left->right:** linear no padding, nearest no padding, linear
padding, nearest padding.

# Objective
Keep up to date with wgpu.
## Solution
Update the wgpu version.
Currently blocked on naga_oil updating to naga 0.14 and releasing a new
version.
3d scenes (or maybe any scene with lighting?) currently don't render
anything due to
```
error: naga_oil bug, please file a report: composer failed to build a valid header: Type [2] '' is invalid
= Capability Capabilities(CUBE_ARRAY_TEXTURES) is required
```
I'm not sure what should be passed in for `wgpu::InstanceFlags`, or if we want to make the gles3minorversion configurable (might be useful for debugging?)
Currently blocked on https://github.com/bevyengine/naga_oil/pull/63, and https://github.com/gfx-rs/wgpu/issues/4569 to be fixed upstream in wgpu first.
## Known issues
Amd+windows+vulkan has issues with texture_binding_arrays (see the image [here](https://github.com/bevyengine/bevy/pull/10266#issuecomment-1819946278)), but that'll be fixed in the next wgpu/naga version, and you can just use dx12 as a workaround for now (Amd+linux mesa+vulkan texture_binding_arrays are fixed though).
---
## Changelog
Updated wgpu to 0.18, naga to 0.14.2, and naga_oil to 0.11.
- Windows desktop GL should now be less painful as it no longer requires Angle.
- You can now toggle shader validation and debug information for debug and release builds using `WgpuSettings.instance_flags` and [InstanceFlags](https://docs.rs/wgpu/0.18.0/wgpu/struct.InstanceFlags.html)
## Migration Guide
- `RenderPassDescriptor` `color_attachments` (as well as `RenderPassColorAttachment`, and `RenderPassDepthStencilAttachment`) now use `StoreOp::Store` or `StoreOp::Discard` instead of a `boolean` to declare whether or not they should be stored.
- `RenderPassDescriptor` now have `timestamp_writes` and `occlusion_query_set` fields. These can safely be set to `None`.
- `ComputePassDescriptor` now have a `timestamp_writes` field. This can be set to `None` for now.
- See the [wgpu changelog](https://github.com/gfx-rs/wgpu/blob/trunk/CHANGELOG.md#v0180-2023-10-25) for additional details
# Objective
add `RenderLayers` awareness to lights. lights default to
`RenderLayers::layer(0)`, and must intersect the camera entity's
`RenderLayers` in order to affect the camera's output.
note that lights already use renderlayers to filter meshes for shadow
casting. this adds filtering lights per view based on intersection of
camera layers and light layers.
fixes#3462
## Solution
PointLights and SpotLights are assigned to individual views in
`assign_lights_to_clusters`, so we simply cull the lights which don't
match the view layers in that function.
DirectionalLights are global, so we
- add the light layers to the `DirectionalLight` struct
- add the view layers to the `ViewUniform` struct
- check for intersection before processing the light in
`apply_pbr_lighting`
potential issue: when mesh/light layers are smaller than the view layers
weird results can occur. e.g:
camera = layers 1+2
light = layers 1
mesh = layers 2
the mesh does not cast shadows wrt the light as (1 & 2) == 0.
the light affects the view as (1+2 & 1) != 0.
the view renders the mesh as (1+2 & 2) != 0.
so the mesh is rendered and lit, but does not cast a shadow.
this could be fixed (so that the light would not affect the mesh in that
view) by adding the light layers to the point and spot light structs,
but i think the setup is pretty unusual, and space is at a premium in
those structs (adding 4 bytes more would reduce the webgl point+spot
light max count to 240 from 256).
I think typical usage is for cameras to have a single layer, and
meshes/lights to maybe have multiple layers to render to e.g. minimaps
as well as primary views.
if there is a good use case for the above setup and we should support
it, please let me know.
---
## Migration Guide
Lights no longer affect all `RenderLayers` by default, now like cameras
and meshes they default to `RenderLayers::layer(0)`. To recover the
previous behaviour and have all lights affect all views, add a
`RenderLayers::all()` component to the light entity.
# Objective
- Resolves#10853
## Solution
- ~~Changed the name of `Input` struct to `PressableInput`.~~
- Changed the name of `Input` struct to `ButtonInput`.
## Migration Guide
- Breaking Change: Users need to rename `Input` to `ButtonInput` in
their projects.
# Objective
A better alternative version of #10843.
Currently, Bevy has a single `Ray` struct for 3D. To allow better
interoperability with Bevy's primitive shapes (#10572) and some third
party crates (that handle e.g. spatial queries), it would be very useful
to have separate versions for 2D and 3D respectively.
## Solution
Separate `Ray` into `Ray2d` and `Ray3d`. These new structs also take
advantage of the new primitives by using `Direction2d`/`Direction3d` for
the direction:
```rust
pub struct Ray2d {
pub origin: Vec2,
pub direction: Direction2d,
}
pub struct Ray3d {
pub origin: Vec3,
pub direction: Direction3d,
}
```
and by using `Plane2d`/`Plane3d` in `intersect_plane`:
```rust
impl Ray2d {
// ...
pub fn intersect_plane(&self, plane_origin: Vec2, plane: Plane2d) -> Option<f32> {
// ...
}
}
```
---
## Changelog
### Added
- `Ray2d` and `Ray3d`
- `Ray2d::new` and `Ray3d::new` constructors
- `Plane2d::new` and `Plane3d::new` constructors
### Removed
- Removed `Ray` in favor of `Ray3d`
### Changed
- `direction` is now a `Direction2d`/`Direction3d` instead of a vector,
which provides guaranteed normalization
- `intersect_plane` now takes a `Plane2d`/`Plane3d` instead of just a
vector for the plane normal
- `Direction2d` and `Direction3d` now derive `Serialize` and
`Deserialize` to preserve ray (de)serialization
## Migration Guide
`Ray` has been renamed to `Ray3d`.
### Ray creation
Before:
```rust
Ray {
origin: Vec3::ZERO,
direction: Vec3::new(0.5, 0.6, 0.2).normalize(),
}
```
After:
```rust
// Option 1:
Ray3d {
origin: Vec3::ZERO,
direction: Direction3d::new(Vec3::new(0.5, 0.6, 0.2)).unwrap(),
}
// Option 2:
Ray3d::new(Vec3::ZERO, Vec3::new(0.5, 0.6, 0.2))
```
### Plane intersections
Before:
```rust
let result = ray.intersect_plane(Vec2::X, Vec2::Y);
```
After:
```rust
let result = ray.intersect_plane(Vec2::X, Plane2d::new(Vec2::Y));
```
# Objective
The name `TextAlignment` is really deceptive and almost every new user
gets confused about the differences between aligning text with
`TextAlignment`, aligning text with `Style` and aligning text with
anchor (when using `Text2d`).
## Solution
* Rename `TextAlignment` to `JustifyText`. The associated helper methods
are also renamed.
* Improve the doc comments for text explaining explicitly how the
`JustifyText` component affects the arrangement of text.
* Add some extra cases to the `text_debug` example that demonstate the
differences between alignment using `JustifyText` and alignment using
`Style`.

## Changelog
* `TextAlignment` has been renamed to `JustifyText`

# Objective
Fixes#10291
This adds a way to easily log messages once within system which are
called every frame.
## Solution
Opted for a macro-based approach. The fact that the 'once' call is
tracked per call site makes the `log_once!()` macro very versatile and
easy-to-use. I suspect it will be very handy for all of us, but
especially beginners, to get some initial feedback from systems without
spamming up the place!
I've made the macro's return its internal `has_fired` state, for
situations in which that might be useful to know (trigger something else
alongside the log, for example).
Please let me know if I placed the macro's in the right location, and if
you would like me to do something more clever with the macro's
themselves, since its looking quite copy-pastey at the moment. I've
tried ways to replace 5 with 1 macro's, but no success yet.
One downside of this approach is: Say you wish to warn the user if a
resource is invalid. In this situation, the
`resource.is_valid()` check would still be performed every frame:
```rust
fn my_system(my_res: Res<MyResource>) {
if !my_res.is_valid() {
warn_once!("resource is invalid!");
}
}
```
If you want to prevent that, you would still need to introduce a local
boolean. I don't think this is a very big deal, as expensive checks
shouldn't be called every frame in any case.
## Changelog
Added: `trace_once!()`, `debug_once!()`, `info_once!()`, `warn_once!()`,
and `error_once!()` log macros which fire only once per call site.
# Objective
After #6547, `Query::for_each` has been capable of automatic
vectorization on certain queries, which is seeing a notable (>50% CPU
time improvements) for iteration. However, `Query::for_each` isn't
idiomatic Rust, and lacks the flexibility of iterator combinators.
Ideally, `Query::iter` and friends should be able to achieve the same
results. However, this does seem to blocked upstream
(rust-lang/rust#104914) by Rust's loop optimizations.
## Solution
This is an intermediate solution and refactor. This moves the
`Query::for_each` implementation onto the `Iterator::fold`
implementation for `QueryIter` instead. This should result in the same
automatic vectorization optimization on all `Iterator` functions that
internally use fold, including `Iterator::for_each`, `Iterator::count`,
etc.
With this, it should close the gap between the two completely.
Internally, this PR changes `Query::for_each` to use
`query.iter().for_each(..)` instead of the duplicated implementation.
Separately, the duplicate implementations of internal iteration (i.e.
`Query::par_for_each`) now use portions of the current `Query::for_each`
implementation factored out into their own functions.
This also massively cleans up our internal fragmentation of internal
iteration options, deduplicating the iteration code used in `for_each`
and `par_iter().for_each()`.
---
## Changelog
Changed: `Query::for_each`, `Query::for_each_mut`, `Query::for_each`,
and `Query::for_each_mut` have been moved to `QueryIter`'s
`Iterator::for_each` implementation, and still retains their performance
improvements over normal iteration. These APIs are deprecated in 0.13
and will be removed in 0.14.

# Objective
Make ```DynamicSceneBuilder``` more visible to new bevy learners!
```DynamicSceneBuilder``` is likely to be the most appropriate tool to use when creating dynamic scenes in all but the simplest scenarios. However, it's not mentioned in the scene example. This PR aims to fix this.
## Solution
I've modified the comment above where the ```DynamicScene``` is created to note that ```DynamicSceneBuilder``` can also be used to create the scene. I believe this is the best approach to introduce ```DynamicSceneBuilder``` without adding additional complexity to the example.
# Objective
- Shorten paths by removing unnecessary prefixes
## Solution
- Remove the prefixes from many paths which do not need them. Finding
the paths was done automatically using built-in refactoring tools in
Jetbrains RustRover.
# Objective
- Materials should be a more frequent rebind then meshes (due to being
able to use a single vertex buffer, such as in #10164) and therefore
should be in a higher bind group.
---
## Changelog
- For 2d and 3d mesh/material setups (but not UI materials, or other
rendering setups such as gizmos, sprites, or text), mesh data is now in
bind group 1, and material data is now in bind group 2, which is swapped
from how they were before.
## Migration Guide
- Custom 2d and 3d mesh/material shaders should now use bind group 2
`@group(2) @binding(x)` for their bound resources, instead of bind group
1.
- Many internal pieces of rendering code have changed so that mesh data
is now in bind group 1, and material data is now in bind group 2.
Semi-custom rendering setups (that don't use the Material or Material2d
APIs) should adapt to these changes.
# Objective
Related to #10612.
Enable the
[`clippy::manual_let_else`](https://rust-lang.github.io/rust-clippy/master/#manual_let_else)
lint as a warning. The `let else` form seems more idiomatic to me than a
`match`/`if else` that either match a pattern or diverge, and from the
clippy doc, the lint doesn't seem to have any possible false positive.
## Solution
Add the lint as warning in `Cargo.toml`, refactor places where the lint
triggers.
# Objective
- Follow up to #9694
## Solution
- Same api as #9694 but adapted for `BindGroupLayoutEntry`
- Use the same `ShaderStages` visibilty for all entries by default
- Add `BindingType` helper function that mirror the wgsl equivalent and
that make writing layouts much simpler.
Before:
```rust
let layout = render_device.create_bind_group_layout(&BindGroupLayoutDescriptor {
label: Some("post_process_bind_group_layout"),
entries: &[
BindGroupLayoutEntry {
binding: 0,
visibility: ShaderStages::FRAGMENT,
ty: BindingType::Texture {
sample_type: TextureSampleType::Float { filterable: true },
view_dimension: TextureViewDimension::D2,
multisampled: false,
},
count: None,
},
BindGroupLayoutEntry {
binding: 1,
visibility: ShaderStages::FRAGMENT,
ty: BindingType::Sampler(SamplerBindingType::Filtering),
count: None,
},
BindGroupLayoutEntry {
binding: 2,
visibility: ShaderStages::FRAGMENT,
ty: BindingType::Buffer {
ty: bevy::render::render_resource::BufferBindingType::Uniform,
has_dynamic_offset: false,
min_binding_size: Some(PostProcessSettings::min_size()),
},
count: None,
},
],
});
```
After:
```rust
let layout = render_device.create_bind_group_layout(
"post_process_bind_group_layout"),
&BindGroupLayoutEntries::sequential(
ShaderStages::FRAGMENT,
(
texture_2d_f32(),
sampler(SamplerBindingType::Filtering),
uniform_buffer(false, Some(PostProcessSettings::min_size())),
),
),
);
```
Here's a more extreme example in bevy_solari:

---
## Changelog
- Added `BindGroupLayoutEntries` and all `BindingType` helper functions.
## Migration Guide
`RenderDevice::create_bind_group_layout()` doesn't take a
`BindGroupLayoutDescriptor` anymore. You need to provide the parameters
separately
```rust
// 0.12
let layout = render_device.create_bind_group_layout(&BindGroupLayoutDescriptor {
label: Some("post_process_bind_group_layout"),
entries: &[
BindGroupLayoutEntry {
// ...
},
],
});
// 0.13
let layout = render_device.create_bind_group_layout(
"post_process_bind_group_layout",
&[
BindGroupLayoutEntry {
// ...
},
],
);
```

- [x] update the `RenderDevice::create_bind_group_layout()` api to match
the one from `RenderDevice::creat_bind_group()`
- [x] docs
# Objective
- Fixes#7680
- This is an updated for https://github.com/bevyengine/bevy/pull/8899
which had the same objective but fell a long way behind the latest
changes
## Solution
The traits `WorldQueryData : WorldQuery` and `WorldQueryFilter :
WorldQuery` have been added and some of the types and functions from
`WorldQuery` has been moved into them.
`ReadOnlyWorldQuery` has been replaced with `ReadOnlyWorldQueryData`.
`WorldQueryFilter` is safe (as long as `WorldQuery` is implemented
safely).
`WorldQueryData` is unsafe - safely implementing it requires that
`Self::ReadOnly` is a readonly version of `Self` (this used to be a
safety requirement of `WorldQuery`)
The type parameters `Q` and `F` of `Query` must now implement
`WorldQueryData` and `WorldQueryFilter` respectively.
This makes it impossible to accidentally use a filter in the data
position or vice versa which was something that could lead to bugs.
~~Compile failure tests have been added to check this.~~
It was previously sometimes useful to use `Option<With<T>>` in the data
position. Use `Has<T>` instead in these cases.
The `WorldQuery` derive macro has been split into separate derive macros
for `WorldQueryData` and `WorldQueryFilter`.
Previously it was possible to derive both `WorldQuery` for a struct that
had a mixture of data and filter items. This would not work correctly in
some cases but could be a useful pattern in others. *This is no longer
possible.*
---
## Notes
- The changes outside of `bevy_ecs` are all changing type parameters to
the new types, updating the macro use, or replacing `Option<With<T>>`
with `Has<T>`.
- All `WorldQueryData` types always returned `true` for `IS_ARCHETYPAL`
so I moved it to `WorldQueryFilter` and
replaced all calls to it with `true`. That should be the only logic
change outside of the macro generation code.
- `Changed<T>` and `Added<T>` were being generated by a macro that I
have expanded. Happy to revert that if desired.
- The two derive macros share some functions for implementing
`WorldQuery` but the tidiest way I could find to implement them was to
give them a ton of arguments and ask clippy to ignore that.
## Changelog
### Changed
- Split `WorldQuery` into `WorldQueryData` and `WorldQueryFilter` which
now have separate derive macros. It is not possible to derive both for
the same type.
- `Query` now requires that the first type argument implements
`WorldQueryData` and the second implements `WorldQueryFilter`
## Migration Guide
- Update derives
```rust
// old
#[derive(WorldQuery)]
#[world_query(mutable, derive(Debug))]
struct CustomQuery {
entity: Entity,
a: &'static mut ComponentA
}
#[derive(WorldQuery)]
struct QueryFilter {
_c: With<ComponentC>
}
// new
#[derive(WorldQueryData)]
#[world_query_data(mutable, derive(Debug))]
struct CustomQuery {
entity: Entity,
a: &'static mut ComponentA,
}
#[derive(WorldQueryFilter)]
struct QueryFilter {
_c: With<ComponentC>
}
```
- Replace `Option<With<T>>` with `Has<T>`
```rust
/// old
fn my_system(query: Query<(Entity, Option<With<ComponentA>>)>)
{
for (entity, has_a_option) in query.iter(){
let has_a:bool = has_a_option.is_some();
//todo!()
}
}
/// new
fn my_system(query: Query<(Entity, Has<ComponentA>)>)
{
for (entity, has_a) in query.iter(){
//todo!()
}
}
```
- Fix queries which had filters in the data position or vice versa.
```rust
// old
fn my_system(query: Query<(Entity, With<ComponentA>)>)
{
for (entity, _) in query.iter(){
//todo!()
}
}
// new
fn my_system(query: Query<Entity, With<ComponentA>>)
{
for entity in query.iter(){
//todo!()
}
}
// old
fn my_system(query: Query<AnyOf<(&ComponentA, With<ComponentB>)>>)
{
for (entity, _) in query.iter(){
//todo!()
}
}
// new
fn my_system(query: Query<Option<&ComponentA>, Or<(With<ComponentA>, With<ComponentB>)>>)
{
for entity in query.iter(){
//todo!()
}
}
```

# Objective
The `nondeterministic_system_order` example doesn't actually detect and
log its deliberate order ambiguities! It should, tho.
## Solution
Update the schedule label, and explain in a comment that you can't turn
it on for the whole `Main` schedule in one go (alas, that would be nice,
but it makes sense that it doesn't work that way).
# Objective
Problems:
* The clipped, non-visible regions of UI nodes are interactive.
* `RelativeCursorPostion` is set relative to the visible part of the
node. It should be relative to the whole node.
* The `RelativeCursorPostion::mouse_over` method returns `true` when the
mouse is over a clipped part of a node.
fixes#10470
## Solution
Intersect a node's bounding rect with its clipping rect before checking
if it contains the cursor.
Added the field `normalized_visible_node_rect` to
`RelativeCursorPosition`. This is set to the bounds of the unclipped
area of the node rect by `ui_focus_system` expressed in normalized
coordinates relative to the entire node.
Instead of checking if the normalized cursor position lies within a unit
square, it instead checks if it is contained by
`normalized_visible_node_rect`.
Added outlines to the `overflow` example that appear when the cursor is
over the visible part of the images, but not the clipped area.
---
## Changelog
* `ui_focus_system` intersects a node's bounding rect with its clipping
rect before checking if mouse over.
* Added the field `normalized_visible_node_rect` to
`RelativeCursorPosition`. This is set to the bounds of the unclipped
area of the node rect by `ui_focus_system` expressed in normalized
coordinates relative to the entire node.
* `RelativeCursorPostion` is calculated relative to the whole node's
position and size, not only the visible part.
* `RelativeCursorPosition::mouse_over` only returns true when the mouse
is over an unclipped region of the UI node.
* Removed the `Deref` and `DerefMut` derives from
`RelativeCursorPosition` as it is no longer a single field struct.
* Added some outlines to the `overflow` example that respond to
`Interaction` changes.
## Migration Guide
The clipped areas of UI nodes are no longer interactive.
`RelativeCursorPostion` is now calculated relative to the whole node's
position and size, not only the visible part. Its `mouse_over` method
only returns true when the cursor is over an unclipped part of the node.
`RelativeCursorPosition` no longer implements `Deref` and `DerefMut`.
# Objective
- I've been experimenting with different patterns to try and make async
tasks more convenient. One of the better ones I've found is to return a
command queue to allow for deferred &mut World access. It can be
convenient to check for task completion in a normal system, but it is
hard to do something with the command queue after getting it back. This
pr adds a `append` to Commands. This allows appending the returned
command queue onto the system's commands.
## Solution
- I edited the async compute example to use the new `append`, but not
sure if I should keep the example changed as this might be too
opinionated.
## Future Work
- It would be very easy to pull the pattern used in the example out into
a plugin or a external crate, so users wouldn't have to add the checking
system.
---
## Changelog
- add `append` to `Commands` and `CommandQueue`
# Objective
- The current shader code is misleading since it makes it look like a
struct is passed to the bind group 0 but in reality only the color is
passed. They just happen to have the exact same memory layout so wgsl
doesn't complain and it works.
- The struct is defined after the `impl Material` block which is
backwards from pretty much every other usage of the `impl` block in
bevy.
## Solution
- Remove the unnecessary struct in the shader
- move the impl block
# Objective
- Fix adding `#![allow(clippy::type_complexity)]` everywhere. like #9796
## Solution
- Use the new [lints] table that will land in 1.74
(https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#lints)
- inherit lint to the workspace, crates and examples.
```
[lints]
workspace = true
```
## Changelog
- Bump rust version to 1.74
- Enable lints table for the workspace
```toml
[workspace.lints.clippy]
type_complexity = "allow"
```
- Allow type complexity for all crates and examples
```toml
[lints]
workspace = true

# Objective
- Fixes#10518
## Solution
I've added a method to `LoadContext`, `load_direct_with_reader`, which
mirrors the behaviour of `load_direct` with a single key difference: it
is provided with the `Reader` by the caller, rather than getting it from
the contained `AssetServer`. This allows for an `AssetLoader` to process
its `Reader` stream, and then directly hand the results off to the
`LoadContext` to handle further loading. The outer `AssetLoader` can
control how the `Reader` is interpreted by providing a relevant
`AssetPath`.
For example, a Gzip decompression loader could process the asset
`images/my_image.png.gz` by decompressing the bytes, then handing the
decompressed result to the `LoadContext` with the new path
`images/my_image.png.gz/my_image.png`. This intuitively reflects the
nature of contained assets, whilst avoiding unintended behaviour, since
the generated path cannot be a real file path (a file and folder of the
same name cannot coexist in most file-systems).
```rust
#[derive(Asset, TypePath)]
pub struct GzAsset {
pub uncompressed: ErasedLoadedAsset,
}
#[derive(Default)]
pub struct GzAssetLoader;
impl AssetLoader for GzAssetLoader {
type Asset = GzAsset;
type Settings = ();
type Error = GzAssetLoaderError;
fn load<'a>(
&'a self,
reader: &'a mut Reader,
_settings: &'a (),
load_context: &'a mut LoadContext,
) -> BoxedFuture<'a, Result<Self::Asset, Self::Error>> {
Box::pin(async move {
let compressed_path = load_context.path();
let file_name = compressed_path
.file_name()
.ok_or(GzAssetLoaderError::IndeterminateFilePath)?
.to_string_lossy();
let uncompressed_file_name = file_name
.strip_suffix(".gz")
.ok_or(GzAssetLoaderError::IndeterminateFilePath)?;
let contained_path = compressed_path.join(uncompressed_file_name);
let mut bytes_compressed = Vec::new();
reader.read_to_end(&mut bytes_compressed).await?;
let mut decoder = GzDecoder::new(bytes_compressed.as_slice());
let mut bytes_uncompressed = Vec::new();
decoder.read_to_end(&mut bytes_uncompressed)?;
// Now that we have decompressed the asset, let's pass it back to the
// context to continue loading
let mut reader = VecReader::new(bytes_uncompressed);
let uncompressed = load_context
.load_direct_with_reader(&mut reader, contained_path)
.await?;
Ok(GzAsset { uncompressed })
})
}
fn extensions(&self) -> &[&str] {
&["gz"]
}
}
```
Because this example is so prudent, I've included an
`asset_decompression` example which implements this exact behaviour:
```rust
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.init_asset::<GzAsset>()
.init_asset_loader::<GzAssetLoader>()
.add_systems(Startup, setup)
.add_systems(Update, decompress::<Image>)
.run();
}
fn setup(mut commands: Commands, asset_server: Res<AssetServer>) {
commands.spawn(Camera2dBundle::default());
commands.spawn((
Compressed::<Image> {
compressed: asset_server.load("data/compressed_image.png.gz"),
..default()
},
Sprite::default(),
TransformBundle::default(),
VisibilityBundle::default(),
));
}
fn decompress<A: Asset>(
mut commands: Commands,
asset_server: Res<AssetServer>,
mut compressed_assets: ResMut<Assets<GzAsset>>,
query: Query<(Entity, &Compressed<A>)>,
) {
for (entity, Compressed { compressed, .. }) in query.iter() {
let Some(GzAsset { uncompressed }) = compressed_assets.remove(compressed) else {
continue;
};
let uncompressed = uncompressed.take::<A>().unwrap();
commands
.entity(entity)
.remove::<Compressed<A>>()
.insert(asset_server.add(uncompressed));
}
}
```
A key limitation to this design is how to type the internally loaded
asset, since the example `GzAssetLoader` is unaware of the internal
asset type `A`. As such, in this example I store the contained asset as
an `ErasedLoadedAsset`, and leave it up to the consumer of the `GzAsset`
to handle typing the final result, which is the purpose of the
`decompress` system. This limitation can be worked around by providing
type information to the `GzAssetLoader`, such as `GzAssetLoader<Image,
ImageAssetLoader>`, but this would require registering the asset loader
for every possible decompression target.
Aside from this limitation, nested asset containerisation works as an
end user would expect; if the user registers a `TarAssetLoader`, and a
`GzAssetLoader`, then they can load assets with compound
containerisation, such as `images.tar.gz`.
---
## Changelog
- Added `LoadContext::load_direct_with_reader`
- Added `asset_decompression` example
## Notes
- While I believe my implementation of a Gzip asset loader is
reasonable, I haven't included it as a public feature of `bevy_asset` to
keep the scope of this PR as focussed as possible.
- I have included `flate2` as a `dev-dependency` for the example; it is
not included in the main dependency graph.
# Objective
- Fixes#10532
## Solution
I've updated the various `Event` send methods to return the sent
`EventId`(s). Since these methods previously returned nothing, and this
information is cheap to copy, there should be minimal negative
consequences to providing this additional information. In the case of
`send_batch`, an iterator is returned built from `Range` and `Map`,
which only consumes 16 bytes on the stack with no heap allocations for
all batch sizes. As such, the cost of this information is negligible.
These changes are reflected for `EventWriter` and `World`. For `World`,
the return types are optional to account for the possible lack of an
`Events` resource. Again, these methods previously returned no
information, so its inclusion should only be a benefit.
## Usage
Now when sending events, the IDs of those events is available for
immediate use:
```rust
// Example of a request-response system where the requester can track handled requests.
/// A system which can make and track requests
fn requester(
mut requests: EventWriter<Request>,
mut handled: EventReader<Handled>,
mut pending: Local<HashSet<EventId<Request>>>,
) {
// Check status of previous requests
for Handled(id) in handled.read() {
pending.remove(&id);
}
if !pending.is_empty() {
error!("Not all my requests were handled on the previous frame!");
pending.clear();
}
// Send a new request and remember its ID for later
let request_id = requests.send(Request::MyRequest { /* ... */ });
pending.insert(request_id);
}
/// A system which handles requests
fn responder(
mut requests: EventReader<Request>,
mut handled: EventWriter<Handled>,
) {
for (request, id) in requests.read_with_id() {
if handle(request).is_ok() {
handled.send(Handled(id));
}
}
}
```
In the above example, a `requester` system can send request events, and
keep track of which ones are currently pending by `EventId`. Then, a
`responder` system can act on that event, providing the ID as a
reference that the `requester` can use. Before this PR, it was not
trivial for a system sending events to keep track of events by ID. This
is unfortunate, since for a system reading events, it is trivial to
access the ID of a event.
---
## Changelog
- Updated `Events`:
- Added `send_batch`
- Modified `send` to return the sent `EventId`
- Modified `send_default` to return the sent `EventId`
- Updated `EventWriter`
- Modified `send_batch` to return all sent `EventId`s
- Modified `send` to return the sent `EventId`
- Modified `send_default` to return the sent `EventId`
- Updated `World`
- Modified `send_event` to return the sent `EventId` if sent, otherwise
`None`.
- Modified `send_event_default` to return the sent `EventId` if sent,
otherwise `None`.
- Modified `send_event_batch` to return all sent `EventId`s if sent,
otherwise `None`.
- Added unit test `test_send_events_ids` to ensure returned `EventId`s
match the sent `Event`s
- Updated uses of modified methods.
## Migration Guide
### `send` / `send_default` / `send_batch`
For the following methods:
- `Events::send`
- `Events::send_default`
- `Events::send_batch`
- `EventWriter::send`
- `EventWriter::send_default`
- `EventWriter::send_batch`
- `World::send_event`
- `World::send_event_default`
- `World::send_event_batch`
Ensure calls to these methods either handle the returned value, or
suppress the result with `;`.
```rust
// Now fails to compile due to mismatched return type
fn send_my_event(mut events: EventWriter<MyEvent>) {
events.send_default()
}
// Fix
fn send_my_event(mut events: EventWriter<MyEvent>) {
events.send_default();
}
```
This will most likely be noticed within `match` statements:
```rust
// Before
match is_pressed {
true => events.send(PlayerAction::Fire),
// ^--^ No longer returns ()
false => {}
}
// After
match is_pressed {
true => {
events.send(PlayerAction::Fire);
},
false => {}
}
```

# Objective
Related to #10472.
Not having a hardcoded scale factor makes comparing results from these
stress tests difficult.
Contributors using high dpi screens may be rendering 4x as many pixels
as others (or more). Stress tests may have different behavior when moved
from one monitor in a dual setup to another. At very high resolutions,
different parts of the engine / hardware are being stressed.
1080p is also a far more common resolution for gaming.
## Solution
Use a consistent 1080p with `scale_factor_override: 1.0` everywhere.
In #9903, this sort of change was added specifically to `bevymark` and
`many_cubes` but it makes sense to do it everywhere.
## Discussion
- Maybe we should have a command line option, environment variable, or
`CI_TESTING_CONFIG` option for 1080p / 1440p / 4k.
- Will these look odd (small text?) when screenshotted and shown in the
example showcase? The aspect ratio is the same, but they will be
downscaled from 1080p instead of ~720p.
- Maybe there are other window properties that should be consistent
across stress tests. e.g. `resizable: false`.
- Should we add a `stress_test_window(title)` helper or something?
- Bevymark (pre-10472) was intentionally 800x600 to match "bunnymark", I
believe. I don't personally think this is very important.
