# Objective
- An attempt at improving the wording surrounding the contributing link
- Fixes#16609
## Solution
- I mostly took Alice's wording and wrote it how I would have said it.
No idea if it's also "clunky", but something's better than nothing
## Testing

# Objective
When preparing `GpuImage`s, we currently discard the
`depth_or_array_layers` of the `Image`'s size by converting it into a
`UVec2`.
Fixes#16715.
## Solution
Change `GpuImage::size` to `Extent3d`, and just pass that through when
creating `GpuImage`s.
Also copy the `aspect_ratio`, and `size` (now `size_2d` for
disambiguation from the field) functions from `Image` to `GpuImage` for
ease of use with 2D textures.
I originally copied all size-related functions (like `width`, and
`height`), but i think they are unnecessary considering how visible the
`size` field on `GpuImage` is compared to `Image`.
## Testing
Tested via `cargo r -p ci` for everything except docs, when generating
docs it keeps spitting out a ton of
```
error[E0554]: `#![feature]` may not be used on the stable release channel
--> crates/bevy_dylib/src/lib.rs:1:21
|
1 | #![cfg_attr(docsrs, feature(doc_auto_cfg))]
|
```
Not sure why this is happening, but it also happens without my changes,
so it's almost certainly some strange issue specific to my machine.
## Migration Guide
- `GpuImage::size` is now an `Extent3d`. To easily get 2D size, use
`size_2d()`.
# Objective
Example error message beforehand:
```
error[B0001]: Query<&mut Data, ()> in system bevytest::main::{{closure}} accesses component(s)Data in a way that conflicts with a previous…
```
# Objective
Implement a new `AssetChanged` query filter that allows users to query
for entities whose related assets may have changed.
- Closes https://github.com/bevyengine/bevy/issues/5069
- Unblocks #16420. Currently, `cold-specialization`, a key rendering
optimization for unlocking ancillary benefits of the retained render
world, is blocked on being unable detect all scenarios in which an
entity's mesh/material changes using events and observers. An
`AssetChanged` filter will drastically simplify our implementation and
be more robust to future changes.
Originally implemented by @nicopap in #5080.
## Solution
- Adds a new `AssetChanged` query filter that initializes a
`AssetChanges<A>` resource that tracks changed assets and ticks in
`asset_events`.
- ~Reverts #13343 and changes the api of `get_state` to accept `impl
Into<UnsafeWorldCell<'w>>` to allow accessing the `AssetChanges<A>`
resource.~
- Adds a `AsAssetId` trait used for newtype handle wrappers (e.g.
`Mesh3d`) that allows associating a component with the underlying
`Asset` it represents.
## Testing
- Tests are added for `AssetChanged`.
- TBD on performance. We are going to add this `Mesh3d` and
`MeshMaterial3d` (etc) in the renderer. Long term wins in render
performance this unblocks should swamp tracking overhead for any
realistic workload.
## Migration Guide
- The `asset_events` system is no longer public. Users should order
their systems relative to the `AssetEvents` system set.

# Objective
Expand `track_change_detection` feature to also track entity spawns and
despawns. Use this to create better error messages.
# Solution
Adds `Entities::entity_get_spawned_or_despawned_by` as well as `{all
entity reference types}::spawned_by`.
This also removes the deprecated `get_many_entities_mut` & co (and
therefore can't land in 0.15) because we don't yet have no Polonius.
## Testing
Added a test that checks that the locations get updated and these
updates are ordered correctly vs hooks & observers.
---
## Showcase
Access location:
```rust
let mut world = World::new();
let entity = world.spawn_empty().id();
println!("spawned by: {}", world.entity(entity).spawned_by());
```
```
spawned by: src/main.rs:5:24
```
Error message (with `track_change_detection`):
```rust
world.despawn(entity);
world.entity(entity);
```
```
thread 'main' panicked at src/main.rs:11:11:
Entity 0v1#4294967296 was despawned by src/main.rs:10:11
```
and without:
```
thread 'main' panicked at src/main.rs:11:11:
Entity 0v1#4294967296 does not exist (enable `track_change_detection` feature for more details)
```
Similar error messages now also exists for `Query::get`,
`World::entity_mut`, `EntityCommands` creation and everything that
causes `B0003`, e.g.
```
error[B0003]: Could not insert a bundle (of type `MaterialMeshBundle<StandardMaterial>`) for entity Entity { index: 7, generation: 1 }, which was despawned by src/main.rs:10:11. See: https://bevyengine.org/learn/errors/#b0003

The only thing that was preventing `extract_meshes_for_gpu_building` and
`extract_mesh_materials` from running in parallel was the
`ResMut<RenderMeshMaterialIds>`. This lookup can be safely moved to the
`collect_meshes_for_gpu_building` phase, which runs after the extraction
phase.
This results in a small win on `many_cubes`. `extract_mesh_materials` is
currently nonretained, so it's still slow, but running it in parallel is
an easy win.
Before:
After:
Currently, `check_visibility` is parameterized over a query filter that
specifies the type of potentially-visible object. This has the
unfortunate side effect that we need a separate system,
`mark_view_visibility_as_changed_if_necessary`, to trigger view
visibility change detection. That system is quite slow because it must
iterate sequentially over all entities in the scene.
This PR moves the query filter from `check_visibility` to a new
component, `VisibilityClass`. `VisibilityClass` stores a list of type
IDs, each corresponding to one of the query filters we used to use.
Because `check_visibility` is no longer specialized to the query filter
at the type level, Bevy now only needs to invoke it once, leading to
better performance as `check_visibility` can do change detection on the
fly rather than delegating it to a separate system.
This commit also has ergonomic improvements, as there's no need for
applications that want to add their own custom renderable components to
add specializations of the `check_visibility` system to the schedule.
Instead, they only need to ensure that the `ViewVisibility` component is
properly kept up to date. The recommended way to do this, and the way
that's demonstrated in the `custom_phase_item` and
`specialized_mesh_pipeline` examples, is to make `ViewVisibility` a
required component and to add the type ID to it in a component add hook.
This patch does this for `Mesh3d`, `Mesh2d`, `Sprite`, `Light`, and
`Node`, which means that most app code doesn't need to change at all.
Note that, although this patch has a large impact on the performance of
visibility determination, it doesn't actually improve the end-to-end
frame time of `many_cubes`. That's because the render world was already
effectively hiding the latency from
`mark_view_visibility_as_changed_if_necessary`. This patch is, however,
necessary for *further* improvements to `many_cubes` performance.
`many_cubes` trace before:
`many_cubes` trace after:
## Migration Guide
* `check_visibility` no longer takes a `QueryFilter`, and there's no
need to add it manually to your app schedule anymore for custom
rendering items. Instead, entities with custom renderable components
should add the appropriate type IDs to `VisibilityClass`. See
`custom_phase_item` for an example.
# Objective

# Objective
When calling any of the `sort` methods on a `QueryManyIter` with mutable
data, `collect_inner()` must be called before fetching items. Remove the
need for that call.
## Solution
Have the `sort` methods `collect()` the entity list into a `Vec` before
returning.
# Objective
Allow resources to be accessed soundly by `QueryData` and `QueryFilter`
implementations.
This mostly works today, and is used in `bevy-trait-query` and will be
used by #16810. The problem is that the access is not made visible to
the executor, so it would be possible for a system with resource access
in a query to run concurrently with a system that accesses the resource
with `ResMut`, resulting in Undefined Behavior.
## Solution
Define calling `add_resource_read` or `add_resource_write` in
`WorldQuery::update_component_access` to be a supported way to declare
resource access in a query.
Modify `QueryState::new_with_access` to check for resource access and
report it in `archetype_component_acccess`.
Modify `FilteredAccess::is_compatible` to consider resource access
conflicting even on queries with disjoint filters.
# Objective
- Fixes#16802, part of #16801, extracted from #16770.
## Solution
- Fix `compile_fail_utils`'s example test so that it now compiles.
- Bless the results, which were outdated.
## Testing
- `cd tools/compile_fail_utils && cargo check --all-targets`
- `cd tools/compile_fail_utils && cargo test --test example`
# Objective
- Enable modifying node size after layout.
- Gain access to a node's content_size. `UiSurface` is a private type so
content size can't be looked up.
## Solution
- Make `ComputedNode` fields public.
- Add `content_size` to `ComputedNode`.

This PR adds support for *mixed lighting* to Bevy, whereby some parts of
the scene are lightmapped, while others take part in real-time lighting.
(Here *real-time lighting* means lighting at runtime via the PBR shader,
as opposed to precomputed light using lightmaps.) It does so by adding a
new field, `affects_lightmapped_meshes` to `IrradianceVolume` and
`AmbientLight`, and a corresponding field
`affects_lightmapped_mesh_diffuse` to `DirectionalLight`, `PointLight`,
`SpotLight`, and `EnvironmentMapLight`. By default, this value is set to
true; when set to false, the light contributes nothing to the diffuse
irradiance component to meshes with lightmaps.
Note that specular light is unaffected. This is because the correct way
to bake specular lighting is *directional lightmaps*, which we have no
support for yet.
There are two general ways I expect this field to be used:
1. When diffuse indirect light is baked into lightmaps, irradiance
volumes and reflection probes shouldn't contribute any diffuse light to
the static geometry that has a lightmap. That's because the baking tool
should have already accounted for it, and in a higher-quality fashion,
as lightmaps typically offer a higher effective texture resolution than
the light probe does.
2. When direct diffuse light is baked into a lightmap, punctual lights
shouldn't contribute any diffuse light to static geometry with a
lightmap, to avoid double-counting. It may seem odd to bake *direct*
light into a lightmap, as opposed to indirect light. But there is a use
case: in a scene with many lights, avoiding light leaks requires shadow
mapping, which quickly becomes prohibitive when many lights are
involved. Baking lightmaps allows light leaks to be eliminated on static
geometry.
A new example, `mixed_lighting`, has been added. It demonstrates a sofa
(model from the [glTF Sample Assets]) that has been lightmapped offline
using [Bakery]. It has four modes:
1. In *baked* mode, all objects are locked in place, and all the diffuse
direct and indirect light has been calculated ahead of time. Note that
the bottom of the sphere has a red tint from the sofa, illustrating that
the baking tool captured indirect light for it.
2. In *mixed direct* mode, lightmaps capturing diffuse direct and
indirect light have been pre-calculated for the static objects, but the
dynamic sphere has real-time lighting. Note that, because the diffuse
lighting has been entirely pre-calculated for the scenery, the dynamic
sphere casts no shadow. In a real app, you would typically use real-time
lighting for the most important light so that dynamic objects can shadow
the scenery and relegate baked lighting to the less important lights for
which shadows aren't as important. Also note that there is no red tint
on the sphere, because there is no global illumination applied to it. In
an actual game, you could fix this problem by supplementing the
lightmapped objects with an irradiance volume.
3. In *mixed indirect* mode, all direct light is calculated in
real-time, and the static objects have pre-calculated indirect lighting.
This corresponds to the mode that most applications are expected to use.
Because direct light on the scenery is computed dynamically, shadows are
fully supported. As in mixed direct mode, there is no global
illumination on the sphere; in a real application, irradiance volumes
could be used to supplement the lightmaps.
4. In *real-time* mode, no lightmaps are used at all, and all punctual
lights are rendered in real-time. No global illumination exists.
In the example, you can click around to move the sphere, unless you're
in baked mode, in which case the sphere must be locked in place to be
lit correctly.
## Showcase
Baked mode:
Mixed direct mode:
Mixed indirect mode (default):
Real-time mode:
## Migration guide
* The `AmbientLight` resource, the `IrradianceVolume` component, and the
`EnvironmentMapLight` component now have `affects_lightmapped_meshes`
fields. If you don't need to use that field (for example, if you aren't
using lightmaps), you can safely set the field to true.
* `DirectionalLight`, `PointLight`, and `SpotLight` now have
`affects_lightmapped_mesh_diffuse` fields. If you don't need to use that
field (for example, if you aren't using lightmaps), you can safely set
the field to true.

# Objective
- Wgpu barrier tracking is expensive. Making buffers read-only makes
ideally lets wgpu skip worrying about barriers, although in wgpu 23 it
apparently won't yet.
## Solution
- Remove COPY_DST usage from AsBindGroup uniform buffers to allow future
wgpu versions to make this cheaper.
- AsBindGroup never updates buffers, so there's no need for COPY_DST. We
always recreate all buffers and the bind group every time data changes,
which yeah is also expensive.
## Testing
- Ran the animated materials example with/without bindless enabled. No
crashes.
This commit allows Bevy to bind 16 lightmaps at a time, if the current
platform supports bindless textures. Naturally, if bindless textures
aren't supported, Bevy falls back to binding only a single lightmap at a
time. As lightmaps are usually heavily atlased, I doubt many scenes will
use more than 16 lightmap textures.
This has little performance impact now, but it's desirable for us to
reap the benefits of multidraw and bindless textures on scenes that use
lightmaps. Otherwise, we might have to break batches in order to switch
those lightmaps.
Additionally, this PR slightly reduces the cost of binning because it
makes the lightmap index in `Opaque3dBinKey` 32 bits instead of an
`AssetId`.
## Migration Guide
* The `Opaque3dBinKey::lightmap_image` field is now
`Opaque3dBinKey::lightmap_slab`, which is a lightweight identifier for
an entire binding array of lightmaps.
# Objective
Scroll position uses physical coordinates. This means scrolling may go
faster or slower depending on the scroll factor. Also the scrolled
position will change when the scale factor changes.
## Solution
In `ui_layout_system` convert `max_possible_offset` to logical
coordinates before clamping the scroll position. Then convert the
clamped scroll position to physical coordinates before propagating it to
the node's children.
## Testing
Look at the `scroll` example. On main if you change your display's scale
factor the items displayed by the scrolling lists will change because
`ScrollPosition`'s displacement values don't respect scale factor. With
this PR the displacement will be scaled too, and the won't move.
# Objective
`PartialReflect::serializable` is unused in the codebase and should be
removed.
I believe it originally was used to handle serializing certain types but
that's no longer the case.
## Solution
Remove `PartialReflect::serializable`.
## Testing
You can check locally using:
```
cargo check -p bevy_reflect --all-features
```
---
## Migration Guide
`PartialReflect::serializable` has been removed. If you were using this
to pass on serialization information, use `ReflectSerialize` instead or
create custom type data to generate the `Serializable`.
# Objective
We were waiting for 1.83 to address most of these, due to a bug with
`missing_docs` and `expect`. Relates to, but does not entirely complete,
#15059.
## Solution
- Upgrade to 1.83
- Switch `allow(missing_docs)` to `expect(missing_docs)`
- Remove a few now-unused `allow`s along the way, or convert to `expect`
## Objective
Thanks to @eugineerd's work on entity cloning (#16132), we now have a
robust way to copy components between entities. We can extend this to
implement some useful functionality that would have been more
complicated before.
Closes#15350.
## Solution
`EntityCloneBuilder` now automatically includes required components
alongside any component added/removed from the component filter.
Added the following methods to `EntityCloneBuilder`:
- `move_components`
- `without_required_components`
Added the following methods to `EntityWorldMut` and `EntityCommands`:
- `clone_with`
- `clone_components`
- `move_components`
Also added `clone_and_spawn` and `clone_and_spawn_with` to
`EntityWorldMut` (`EntityCommands` already had them).
## Showcase
```
assert_eq!(world.entity(entity_a).get::<B>(), Some(&B));
assert_eq!(world.entity(entity_b).get::<B>(), None);
world.entity_mut(entity_a).clone_components::<B>(entity_b);
assert_eq!(world.entity(entity_a).get::<B>(), Some(&B));
assert_eq!(world.entity(entity_b).get::<B>(), Some(&B));
assert_eq!(world.entity(entity_a).get::<C>(), Some(&C(5)));
assert_eq!(world.entity(entity_b).get::<C>(), None);
world.entity_mut(entity_a).move_components::<C>(entity_b);
assert_eq!(world.entity(entity_a).get::<C>(), None);
assert_eq!(world.entity(entity_b).get::<C>(), Some(&C(5)));
```
# Objective
- Prework for reviving #9582.
## Solution
- Move the two types to volume.rs and made it compile.
- Also `#[reflect(Debug)]` on `Volume` while I'm here.
## Testing
- Ran example locally.
- Rely on CI.
# Objective
- #16813 added the ability to mute sinks and added a new method
`toggle_mute()`.
- Leaving `toggle()` as is creates inconsistency and a bit of confusion
about what is being toggled.
## Solution
- Rename `toggle()` to `toggle_playback()`.
- The choice to use the `_playback` suffix was easy because the method
comment was already telling us what is being toggled: `Toggles playback
of the sink.`
- [Raised in Discord] and got the OK from Alice.
[Raised in Discord]:
https://discord.com/channels/691052431525675048/749430447326625812/1318000355824504905
## Testing
- I ran the example and also updated the instruction text to make it
clear `Space` is toggling the playback not just pausing.
- I added a unit test for `toggle_playback()` because why not.

/>
## Migration Guide
- `AudioSinkPlayback`'s `toggle` method has been renamed to
`toggle_playback`. This was done to create consistency with the
`toggle_mute` method added in
https://github.com/bevyengine/bevy/pull/16813. Change instances of
`toggle` to `toggle_playback`. E.g.:
Before:
```rust
fn pause(keyboard_input: Res<ButtonInput<KeyCode>>, sink: Single<&AudioSink>) {
if keyboard_input.just_pressed(KeyCode::Space) {
sink.toggle();
}
}
```
After:
```rust
fn pause(keyboard_input: Res<ButtonInput<KeyCode>>, sink: Single<&AudioSink>) {
if keyboard_input.just_pressed(KeyCode::Space) {
sink.toggle_playback();
}
}
```
# Objective
Fixes#16659
## Solution
- I just added all the `#[reflect(Component)]` attributes where
necessary.
## Testing
I wrote a small program that scans the bevy code for all structs and
enums that derive `Component` and `Reflect`, but don't have the
attribute `#[reflect(Component)]`.
I don't know if this testing program should be part of the testing suite
of bevy. It takes a bit of time to scan the whole codebase. In any case,
I've published it [here](https://github.com/anlumo/bevy-reflect-check).

```rust
fn mute(
keyboard_input: Res<ButtonInput<KeyCode>>,
mut sink: Single<&mut AudioSink, With<MyMusic>>,
) {
if keyboard_input.just_pressed(KeyCode::KeyM) {
sink.toggle_mute();
}
}
```
- I want to be able to press, say, `M` and mute all my audio. I want
this for dev, but I'm sure it's a useful player setting as well.
- Muting is different to pausing—I don't want to pause my sounds, I want
them to keep playing but with no volume. For example if I have
background music playing which is made up of 5 tracks, I want to be able
to temporarily mute my background music, and if I unmute at, say, track
4, I want to play track 4 rather than have had everything paused and
still be on the first track.
- I want to be able to continue to control the volume of my audio even
when muted. Like in the example, if I have muted my audio but I use the
volume up/down controls, I want Bevy to remember those volume changes so
that when I unmute, the volume corresponds to that.
## Solution
- Add methods to audio to allow muting, unmuting and toggling muting.
- To preserve the user's intended volume, each sink needs to keep track
of a "managed volume".
- I checked `rodio` and I don't see any built in support for doing this,
so I added it to `bevy_audio`.
- I'm interested to hear if this is a good idea or a bad idea. To me,
this API looks nice and looks usable, but I'm aware it involves some
changes to the existing API and now also requires mutable access in some
places compared to before.
- I'm also aware of work on *Better Audio*, but I'm hoping that if this
change isn't too wild it might be a useful addition considering we don't
really know when we'll eventually get better audio.
## Testing
- Update and run the example: `cargo run --example audio_control`
- Run the example: `cargo run --example soundtrack`
- Update and run the example: `cargo run --example spatial_audio_3d`
- Add unit tests.
---
## Showcase
See 2 changed examples that show how you can mute an audio sink and a
spatial audio sink.
## Migration Guide
- The `AudioSinkPlayback` trait now has 4 new methods to allow you to
mute audio sinks: `is_muted`, `mute`, `unmute` and `toggle_mute`. You
can use these methods on `bevy_audio`'s `AudioSink` and
`SpatialAudioSink` components to manage the sink's mute state.
- `AudioSinkPlayback`'s `set_volume` method now takes a mutable
reference instead of an immutable one. Update your code which calls
`set_volume` on `AudioSink` and `SpatialAudioSink` components to take a
mutable reference. E.g.:
Before:
```rust
fn increase_volume(sink: Single<&AudioSink>) {
sink.set_volume(sink.volume() + 0.1);
}
```
After:
```rust
fn increase_volume(mut sink: Single<&mut AudioSink>) {
let current_volume = sink.volume();
sink.set_volume(current_volume + 0.1);
}
```
- The `PlaybackSettings` component now has a `muted` field which you can
use to spawn your audio in a muted state. `PlaybackSettings` also now
has a helper method `muted` which you can use when building the
component. E.g.:
```rust
commands.spawn((
// ...
AudioPlayer::new(asset_server.load("sounds/Windless Slopes.ogg")),
PlaybackSettings::LOOP.with_spatial(true).muted(),
));
```

I forgot to set `BINDLESS_SLOT_COUNT` in `ExtendedMaterial`'s
implementation of `AsBindGroup`, so it didn't actually become bindless.
In fact, it would usually crash with a shader/bind group layout
mismatch, because some parts of Bevy's renderer thought that the
resulting material was bindless while other parts didn't. This commit
corrects the situation.
I had to make `BINDLESS_SLOT_COUNT` a function instead of a constant
because the `ExtendedMaterial` version needs some logic. Unfortunately,
trait methods can't be `const fn`s, so it has to be a runtime function.
# Objective
Destructuring in const code blocks isn't allowed, thus using UIRect in
const code can be a hassle as it initialisation function aren't const.
This Pr makes them const.
## Solution
Removed all destructuring in the UIRect implementation
## Testing
- I've ran a few ui examples to check if i didn't make a mistake,
---
# Objective
- Minor consistency improvement in proc macro code.
- Remove `get_path_direct` since it was only used once anyways and
doesn't add much.
## Solution
- Possibly a minor performance improvement since the `Cargo.toml` wont
be parsed as often.
## Testing
- I don't think it breaks anything.
- This is my first time working on bevy itself. Is there a script to do
a quick verify of my pr?
## Other PR
Similar to #7536 but has no extra dependencies.

## Migration Guide
> This section is optional. If there are no breaking changes, you can
delete this section.
- If this PR is a breaking change (relative to the last release of
Bevy), describe how a user might need to migrate their code to support
these changes
- Simply adding new functionality is not a breaking change.
- Fixing behavior that was definitely a bug, rather than a questionable
design choice is not a breaking change.
# Objective
- Writing an API, and I want to allow users to pass in extra data
alongside the API provided input, and tuples are the most natural
extension in this case.
- Bring `SystemInput` up to par with `SystemParam` for tuple support.
## Solution
- Added impls for tuples up to 8 elements. If you need a 9-arity tuple
or more, write your own `SystemInput` type (it's incredibly simple to
do).
## Testing
- Added a test demonstrating this.
---
## Showcase
Tuples of arbitrary`SystemInput`s are now supported:
```rust
fn by_value((In(a), In(b)): (In<usize>, In<usize>)) -> usize {
a + b
}
fn by_mut((InMut(a), In(b)): (InMut<usize>, In<usize>)) {
*a += b;
}
let mut world = World::new();
let mut by_value = IntoSystem::into_system(by_value);
let mut by_mut = IntoSystem::into_system(by_mut);
by_value.initialize(&mut world);
by_mut.initialize(&mut world);
assert_eq!(by_value.run((12, 24), &mut world), 36);
let mut a = 10;
let b = 5;
by_mut.run((&mut a, b), &mut world);
assert_eq!(*a, 15);
```
# Objective
- Closes#16804.
- This copies over our lint configuration to our benchmarks and fixes
any lints.
## Solution
- Copied over our Clippy configuration from the root `Cargo.toml` to
`benches/Cargo.toml`.
- Fixed any warnings that Clippy emitted.
## Testing
- `cd benches && cargo clippy --benches`
# Objective
- Allow skiping components that don't have ComponentId yet instead of
failing `bevy/query` request.
## Solution
- Describe the solution used to achieve the objective above.
## Testing
My naive approach boils down to:
- bevy/list to get list of all components.
- bevy/query with empty components and has fields and a option that
contains result of the bevy/list.
Before that change I end up with bunch of `Component xxx isn't used in
the world` because some of the components wasn't spawned at any moment
yet in the game. Now it should work.
## Migration Guide
- `BrpQueryParams` now has `strict` boolean field. It serfs as a flag to
fail when encountering an invalid component rather than skipping it.
Defaults to false.
# Objective
Fixes#15485.
## Solution
Deletes the field! The `meta` field had no way to access or mutate it.
## Testing
- It builds!
---
## Migration Guide
- `ErasedAssetLoader` now takes a borrow to `AssetMetaDyn` instead of a
`Box`.
- `LoadedAsset::new_with_dependencies` no longer requires a `meta`
argument.
- `LoadContext::finish` no longer requires a `meta` argument.
# Objective
- `PointerInteraction` components should be updated before sending
picking events. Otherwise they will be stale when event observers run.
- Allow inserting logic before picking events but after
`PointerInteraction` components have been updated.
## Solution
- Reorder systems in `PickSet::Focus`.
This patch replaces the undocumented `NoGpuCulling` component with a new
component, `NoIndirectDrawing`, effectively turning indirect drawing on
by default. Indirect mode is needed for the recently-landed multidraw
feature (#16427). Since multidraw is such a win for performance, when
that feature is supported the small performance tax that indirect mode
incurs is virtually always worth paying.
To ensure that custom drawing code such as that in the
`custom_shader_instancing` example continues to function, this commit
additionally makes GPU culling take the `NoFrustumCulling` component
into account.
This PR is an alternative to #16670 that doesn't break the
`custom_shader_instancing` example. **PR #16755 should land first in
order to avoid breaking deferred rendering, as multidraw currently
breaks it**.
## Migration Guide
* Indirect drawing (GPU culling) is now enabled by default, so the
`GpuCulling` component is no longer available. To disable indirect mode,
which may be useful with custom render nodes, add the new
`NoIndirectDrawing` component to your camera.
## Objective
Some structs and methods in the ECS internals have names that don't
describe their purpose very well, and sometimes don't have docs either.
Also, the function `remove_bundle_from_archetype` is a counterpart to
`BundleInfo::add_bundle_to_archetype`, but isn't a method and is in a
different file.
## Solution
- Renamed the following structs and added docs:
| Before | After |
|----------------------|------------------------------|
| `AddBundle` | `ArchetypeAfterBundleInsert` |
| `InsertBundleResult` | `ArchetypeMoveType` |
- Renamed the following methods:
| Before | After |
|---------------------------------------|----------------------------------------------|
| `Edges::get_add_bundle` | `Edges::get_archetype_after_bundle_insert` |
| `Edges::insert_add_bundle` |
`Edges::cache_archetype_after_bundle_insert` |
| `Edges::get_remove_bundle` |
`Edges::get_archetype_after_bundle_remove` |
| `Edges::insert_remove_bundle` |
`Edges::cache_archetype_after_bundle_remove` |
| `Edges::get_take_bundle` | `Edges::get_archetype_after_bundle_take` |
| `Edges::insert_take_bundle` |
`Edges::cache_archetype_after_bundle_take` |
- Moved `remove_bundle_from_archetype` from `world/entity_ref.rs` to
`BundleInfo`. I left the function in entity_ref in the first commit for
comparison, look there for the diff of comments and whatnot.
- Tidied up docs:
- General grammar and spacing.
- Made the usage of "insert" and "add" more consistent.
- Removed references to information that isn't there.
- Renamed `BundleInfo::add_bundle_to_archetype` to
`BundleInfo::insert_bundle_into_archetype` for consistency.
# Objective
I was curious to use the newly created `bevy_input_focus`, but I found
some issues with it
- It was only implementing traits for `World`.
- Lack of tests
- `is_focus_within` logic was incorrect.
## Solution
This PR includes some improvements to the `bevy_input_focus` crate:
- Add new `IsFocusedHelper` that doesn't require access to `&World`. It
implements `IsFocused`
- Remove `IsFocused` impl for `DeferredWorld`. Since it already
implements `Deref<Target=World>` it was just duplication of code.
- impl `SetInputFocus` for `Commands`. There was no way to use
`SetFocusCommand` directly. This allows it.
- The `is_focus_within` logic has been fixed to check descendants.
Previously it was checking if any of the ancestors had focus which is
not correct according to the documentation.
- Added a bunch of unit tests to verify the logic of the crate.
## Testing
- Did you test these changes? If so, how? Yes, running newly added unit
tests.
---
# Objective
Fixes#16776
## Solution
- reflect `&'static Location` as an opaque type
- I've added this to `impls/std.rs` because other core types are there
too. Maybe they should be split out into a `core.rs` in another PR.
- add source location to `EventId` (behind the
`tracking_change_detection` feature flag)
