## Objective
Use the "standard" text size / placement for the new text in these
examples.
Continuation of an effort started here:
https://github.com/bevyengine/bevy/pull/8478
This is definitely not comprehensive. I did the ones that were easy to
find and relatively straightforward updates. I meant to just do
`3d_shapes` and `2d_shapes`, but one thing lead to another.
## Solution
Use `font_size: 20.0`, the default (built-in) font, `Color::WHITE`
(default), and `Val::Px(12.)` from the edges of the screen.
There are a few little drive-by cleanups of defaults not being used,
etc.
## Testing
Ran the changed examples, verified that they still look reasonable.
# Objective
- Fixes https://github.com/bevyengine/bevy/issues/13155
- fixes https://github.com/bevyengine/bevy/issues/13517
- Supercedes https://github.com/bevyengine/bevy/pull/13381
- Requires https://github.com/DioxusLabs/taffy/pull/661
## Solution
- Taffy has been updated to:
- Apply size styles to absolutely positioned children
- Pass the node's `Style` through to the measure function
- Bevy's image measure function has been updated to make use of this
style information
## Notes
- This is currently using a git version of Taffy. If this is tested as
fixing the issue then we can turn that into a Taffy 0.5 release (this
would be the only change between Taffy 0.4 and Taffy 0.5 so upgrading is
not expected to be an issue)
- This implementation may not be completely correct. I would have
preferred to extend Taffy's gentest infrastructure to handle images and
used that to nail down the correct behaviour. But I don't have time for
that atm so we'll have to iterate on this in future. This PR at least
puts that under Bevy's control.
## Testing
- I manually tested the game_menu_example (from
https://github.com/bevyengine/bevy/issues/13155)
- More testing is probably merited
---
## Changelog
No changelog should be required as it fixes a regression on `main` that
was not present in bevy 0.13. The changelog for "Taffy upgrade" may want
to be changed from 0.4 to 0.5 if this change gets merged.

# Objective
In #13343, `WorldQuery::get_state` was constrained from `&World` as the
argument to `&Components`, but `WorldQuery::init_state` hasn't yet been
changed from `&mut World` to match.
Fixes#13358
## Solution
Create a wrapper around `&mut Components` and `&mut Storages` that can
be obtained from `&mut World` with a `component_initializer` method.
This new `ComponentInitializer` re-exposes the API on `&mut Components`
minus the `&mut Storages` parameter where it was present. For the
`&Components` API, it simply derefs to its `components` field.
## Changelog
### Added
The `World::component_initializer` method.
The `ComponentInitializer` struct that re-exposes `Components` API.
### Changed
`WorldQuery::init_state` now takes `&mut ComponentInitializer` instead
of `&mut World`.
## Migration Guide
Instead of passing `&mut World` to `WorldQuery::init_state` directly,
pass in a mutable reference to the struct returned from
`World::component_initializer`.
# Objective
- Fixes#13038
## Solution
- Disable gpu preprocessing when feature
`SAMPLED_TEXTURE_AND_STORAGE_BUFFER_ARRAY_NON_UNIFORM_INDEXING` is not
available
## Testing
- Tested on android device that used to crash
# Objective
- Motion blur does not currently work with skyboxes or anything else
that does not write to depth.
## Solution
- When computing blur, include fragments with no depth, as long as they
are onscreen.
## Testing
- Tested with the examples - the motion_blur example uncovered a bug
with this fix, where offscreen pixels where now being sampled and
causing artifacts.
- Attached example showing the skybox being sampled in the blur (note
the feathering on edges):

```
## Solution
- call `textureSample` from outside the if. both branches are using the
same parameters
# Objective
- In particularly dark scenes, auto-exposure would lead to an unexpected
darkening of the view.
- Fixes#13446.
## Solution
The average luminance should default to something else than 0.0 instead,
when there are no samples. We set it to `settings.min_log_lum`.
## Testing
I was able to reproduce the problem on the `auto_exposure` example by
setting the point light intensity to 2000 and looking into the
right-hand corner. There was a sudden darkening.
Now, the discontinuity is gone.

Currently, either an `EntityRef` or `EntityMut` is required in order to
reflect a component on an entity. This can, however, be generalized to
`FilteredEntityRef` and `FilteredEntityMut`, which are versions of
`EntityRef` and `EntityMut` that restrict the components that can be
accessed. This is useful because dynamic queries yield
`FilteredEntityRef` and `FilteredEntityMut` rows when iterated over.
This commit changes `ReflectComponent::contains()`,
`ReflectComponent::reflect()`, and `ReflectComponent::reflect_mut()` to
take an `Into<FilteredEntityRef>` (in the case of `contains()` and
`reflect()`) and `Into<FilteredEntityMut>` (in the case of
`reflect_mut()`). Fortunately, `EntityRef` and `EntityMut` already
implement the corresponding trait, so nothing else has to be done to the
public API. Note that in order to implement
`ReflectComponent::reflect_mut()` properly, an additional method
`FilteredEntityMut::into_mut()` was required, to match the one on
`EntityMut`.
I ran into this when attempting to implement `QUERY` in the Bevy Remote
Protocol when trying to iterate over rows of dynamic queries and fetch
the associated components without unsafe code. There were other
potential ways to work around this problem, but they required either
reimplementing the query logic myself instead of using regular Bevy
queries or storing entity IDs and then issuing another query to fetch
the associated `EntityRef`. Both of these seemed worse than just
improving the `reflect()` function.
## Migration Guide
* `ReflectComponent::contains`, `ReflectComponent::reflect`, and
`ReflectComponent::reflect_mut` now take `FilteredEntityRef` (in the
case of `contains()` and `reflect()`) and `FilteredEntityMut` (in the
case of `reflect_mut()`) parameters. `FilteredEntityRef` and
`FilteredEntityMut` have very similar APIs to `EntityRef` and
`EntityMut` respectively, but optionally restrict the components that
can be accessed.
# Objective
- `FilteredEntity{Ref,Mut}` various `get` methods never checked that the
given component was present on the entity, only the access allowed
reading/writing them, which is always the case when it is constructed
from a `EntityRef`/`EntityMut`/`EntityWorldMut` (and I guess can also
happen with queries containing `Option<T>` that get transmuted).
- In those cases the various `get` methods were calling
`debug_checked_unwrap` on `None`s, which is UB when debug assertions are
not enabled;
- The goal is thus to fix this soundness issue.
## Solution
- Don't call `debug_checked_unwrap` on those `None` and instead
`flatten` them.
## Testing
- This PR includes regression tests for each combination of
`FilteredEntityRef`/`FilteredEntityMut` and component
present/not-present. The two tests for the not-present cases fail on
`main` but success with this PR changes.
# Objective
- Prevent the case where a hook/observer is triggered but the source
entity/component no longer exists
## Solution
- Re-order command application such that all hooks/observers that are
notified will run before any have a chance to invalidate the result.
## Testing
Updated relevant tests in `bevy_ecs`, all other tests pass.

## Changelog
Fix the bug which led to the crash when user uses any tonemapper without
hdr for rendering sprites and 2d meshes.
# Objective
- Fixes#13521
## Solution
Set `ambient_intensity` to 0.0 in volumetric_fog example.
I chose setting it explicitly over changing the default in order to make
it clear that this needs to be set depending on whether you have an
`EnvironmentMapLight`. See documentation for `ambient_intensity` and
related members.
## Testing
- Run the volumetric_fog example and notice how the light shown in
#13521 is not there anymore, as expected.

I implemented `Reflect` for close to all math types now, except for some
types that it would cause issues (like some boxed types).
## Testing
- Everything seems to still build, will await CI though.
---
## Changelog
- Made close to all math types implement `Reflect`.
# Objective
- Fixes#13503
- Fix other various bugs I noticed while debugging above issue.
## Solution
- Change the antialiasing(AA) method. It was using fwidth which is the
derivative between pixels, but there were a lot of artifacts being added
from this. So just use the sdf value. This aa method probably isn't as
smooth looking, but better than having artifacts. Below is a
visualization of the fwidth.
- Use the internal sdf for drawing the background instead of the
external sdf and extract the border for these type of nodes. This fixed
2 bugs, one with the background coloring the AA pixels on the edge of
rounded borders. And also allows for the border to use a transparent
color.
- Don't extract borders if all the widths are zero.
## Testing
- played a bunch with the example in the linked issue.

### Quick note
I accidentally used the same commit message while resolving a merge

# Objective
Fixes#13427.

I changed the traits, and updated all usages.
## Testing
The `render_primitives` example still works perfectly.

## Changelog
- Made `gizmos.primitive_2d()` and `gizmos.primitive_3d()` take the
primitives by ref.
## Migration Guide
- Any usages of `gizmos.primitive_2d()` and/or `gizmos.primitive_3d()`
need to be updated to pass the primitive in by reference.
# Objective
We introduced a bunch of neat random sampling stuff in this release; we
should do a good job of showing people how to use it, and writing
examples is part of this.
## Solution
A new Math example, `random_sampling`, shows off the `ShapeSample` API
functionality. For the moment, it renders a cube and allows the user to
sample points from its interior or boundary in sets of either 1 or 100:
<img width="1440" alt="Screenshot 2024-05-25 at 1 16 08 PM"
src="https://github.com/bevyengine/bevy/assets/2975848/9cb6f53f-c89a-42c2-8907-b11d294c402a">
On the level of code, these are reflected by two ways of using
`ShapeSample`:
```rust
// Get a single random Vec3:
let sample: Vec3 = match *mode {
Mode::Interior => shape.0.sample_interior(rng),
Mode::Boundary => shape.0.sample_boundary(rng),
};
```
```rust
// Get 100 random Vec3s:
let samples: Vec<Vec3> = match *mode {
Mode::Interior => {
let dist = shape.0.interior_dist();
dist.sample_iter(&mut rng).take(100).collect()
}
Mode::Boundary => {
let dist = shape.0.boundary_dist();
dist.sample_iter(&mut rng).take(100).collect()
}
};
```
## Testing
Run the example!
## Discussion
Maybe in the future it would be nice to show off all of the different
shapes that we have implemented `ShapeSample` for, but I wanted to start
just by demonstrating the functionality. Here, I chose a cube because
it's simple and because it looks good rendered transparently with
backface culling disabled.
This commit, a revamp of #12959, implements screen-space reflections
(SSR), which approximate real-time reflections based on raymarching
through the depth buffer and copying samples from the final rendered
frame. This patch is a relatively minimal implementation of SSR, so as
to provide a flexible base on which to customize and build in the
future. However, it's based on the production-quality [raymarching code
by Tomasz
Stachowiak](https://gist.github.com/h3r2tic/9c8356bdaefbe80b1a22ae0aaee192db).
For a general basic overview of screen-space reflections, see
[1](https://lettier.github.io/3d-game-shaders-for-beginners/screen-space-reflection.html).
The raymarching shader uses the basic algorithm of tracing forward in
large steps, refining that trace in smaller increments via binary
search, and then using the secant method. No temporal filtering or
roughness blurring, is performed at all; for this reason, SSR currently
only operates on very shiny surfaces. No acceleration via the
hierarchical Z-buffer is implemented (though note that
https://github.com/bevyengine/bevy/pull/12899 will add the
infrastructure for this). Reflections are traced at full resolution,
which is often considered slow. All of these improvements and more can
be follow-ups.
SSR is built on top of the deferred renderer and is currently only
supported in that mode. Forward screen-space reflections are possible
albeit uncommon (though e.g. *Doom Eternal* uses them); however, they
require tracing from the previous frame, which would add complexity.
This patch leaves the door open to implementing SSR in the forward
rendering path but doesn't itself have such an implementation.
Screen-space reflections aren't supported in WebGL 2, because they
require sampling from the depth buffer, which Naga can't do because of a
bug (`sampler2DShadow` is incorrectly generated instead of `sampler2D`;
this is the same reason why depth of field is disabled on that
platform).
To add screen-space reflections to a camera, use the
`ScreenSpaceReflectionsBundle` bundle or the
`ScreenSpaceReflectionsSettings` component. In addition to
`ScreenSpaceReflectionsSettings`, `DepthPrepass` and `DeferredPrepass`
must also be present for the reflections to show up. The
`ScreenSpaceReflectionsSettings` component contains several settings
that artists can tweak, and also comes with sensible defaults.
A new example, `ssr`, has been added. It's loosely based on the
[three.js ocean
sample](https://threejs.org/examples/webgl_shaders_ocean.html), but all
the assets are original. Note that the three.js demo has no screen-space
reflections and instead renders a mirror world. In contrast to #12959,
this demo tests not only a cube but also a more complex model (the
flight helmet).
## Changelog
### Added
* Screen-space reflections can be enabled for very smooth surfaces by
adding the `ScreenSpaceReflections` component to a camera. Deferred
rendering must be enabled for the reflections to appear.
# Objective
- We use
[`ci_testing`](https://dev-docs.bevyengine.org/bevy/dev_tools/ci_testing/index.html)
to specify per-example configuration on when to take a screenshot, when
to exit, etc.
- In the future more features may be added, such as #13512. To support
this growth, `ci_testing` should be easier to read and maintain.
## Solution
- Convert `ci_testing.rs` into the folder `ci_testing`, splitting the
configuration and systems into `ci_testing/config.rs` and
`ci_testing/systems.rs`.
- Convert `setup_app` into the plugin `CiTestingPlugin`. This new plugin
is added to both `DefaultPlugins` and `MinimalPlugins`.
- Remove `DevToolsPlugin` from `MinimalPlugins`, since it was only used
for CI testing.
- Clean up some code, add many comments, and add a few unit tests.
## Testing
The most important part is that this still passes all of the CI
validation checks (merge queue), since that is when it will be used the
most. I don't think I changed any behavior, so it should operate the
same.
You can also test it locally using:
```shell
# Run the breakout example, enabling `bevy_ci_testing` and loading the configuration used in CI.
CI_TESTING_CONFIG=".github/example-run/breakout.ron" cargo r --example breakout -F bevy_ci_testing
```
---
## Changelog
- Added `CiTestingPlugin`, which is split off from `DevToolsPlugin`.
- Removed `DevToolsPlugin` from `MinimalPlugins`.
## Migration Guide
Hi maintainers! I believe `DevToolsPlugin` was added within the same
release as this PR, so I don't think a migration guide is needed.
`DevToolsPlugin` is no longer included in `MinimalPlugins`, so you will
need to remove it manually.
```rust
// Before
App::new()
.add_plugins(MinimalPlugins)
.run();
// After
App::new()
.add_plugins(MinimalPlugins)
.add_plugins(DevToolsPlugin)
.run();
```

Added a Grey trait to allow colors to create a generic "grey" color.
This currently assumes the color spaces follow the same gradient, which
I'm pretty sure isn't true, but it should make a "grey-ish" color
relative to the provided intensity.
# Objective
- Implements #13206
## Solution
- A small `Grey` trait was added and implemented for the common color
kinds.
## Testing
- Currently untested, unit tests exposed the non-linear relation between
colors. I am debating adding an example to show this, as I have no idea
what color space represents what relation of grey, and I figure others
may be similarly confused.
## Changelog
- The `Grey` trait was added, and the corresponding `grey`
## BREAKING CHANGES
The const qualifier for LinearRGBA::gray was removed (the symbol still
exists via a trait, it's just not const anymore)
# Objective
The `ConicalFrustum` primitive should support meshing.
## Solution
Implement meshing for the `ConicalFrustum` primitive. The implementation
is nearly identical to `Cylinder` meshing, but supports two radii.
The default conical frustum is equivalent to a cone with a height of 1
and a radius of 0.5, truncated at half-height.
# Objective
This is just cleanup; we've got some more renderable gizmos and
primitives now that hadn't been added to this example, so let's add
them.
## Solution
In the `render_primitives` example:
- Added `Triangle3d` mesh
- Wrote `primitive_3d` gizmo impl for `Triangle3d` and added the gizmo
- Added `Tetrahedron` mesh and gizmo
I also made the 2d triangle bigger, since it was really small.
## Testing
You can just run the example to see that everything turned out all
right.
## Other
Feel free to let me know if there are other primitives that I missed;
I'm happy to tack them onto this PR.
# Objective
I'm reading some of the rendering code for the first time; and using
this opportunity to flesh out some docs for the parts that I did not

# Objective
Supercedes #12881 . Added a simple implementation that allows the user
to react to multiple asset loads both synchronously and asynchronously.
## Solution
Added `load_acquire`, that holds an item and drops it when loading is
finished or failed.
When used synchronously
Hold an `Arc<()>`, check for `Arc::strong_count() == 1` when all loading
completed.
When used asynchronously
Hold a `SemaphoreGuard`, await on `acquire_all` for completion.
This implementation has more freedom than the original in my opinion.

enums. It's used for the `FromReflect::from_reflect` implementation and
the `Reflect::try_apply` implementation.
Due to the complexity of enums, this function is understandably a little
messy and difficult to extend.
## Solution
Clean up the `enum_utility` module.
Now "clean" is a bit subjective. I believe my solution is "cleaner" in
that the logic to generate the tokens are strictly coupled with the
intended usage. Because of this, `try_apply` is also no longer strictly
coupled with `from_reflect`.
This makes it easier to extend with new functionality, which is
something I'm doing in a future unrelated PR that I have based off this
one.
## Testing
There shouldn't be any testing required other than ensuring that the
project still builds and that CI passes.
# Objective
The current query iterators cannot be used in positions with a `Debug`
bound.
F.e. when they are packaged in `Result` in the error position, `expect`
cannot be called on them.
Required for `QueryManyIter::entities_all_unique` in #13477.
## Solution
Add simple `Debug` impls that print the query iterator names.
## Changelog
`QueryIter`, `QueryManyIter`, `QueryCombinationIter`, and
`QuerySortedIter` now implement `Debug`.
