# Objective
Fixes#13866
## Solution
Add `insert_before` in **FixedMainScheduleOrder** and
**MainScheduleOrder**, add `insert_startup_before` in
**MainScheduleOrder**, applying the same logic as `insert_after`, except
for parameters naming and insertion index.
# Objective
- Fix#14295
## Solution
- Early out when `GFBD::get_index_and_compare_data` returns None.
## Testing
- Tested on a selection of examples including `many_foxes` and
`3d_shapes`.
- Resolved the original issue in `bevy_vector_shapes`.
# Objective
Spamming the window close button on window may trigger a panic.
```
thread 'main' panicked at <Bevy repo>\crates\bevy_ecs\src\system\commands\mod.rs:1320:13:
error[B0003]: Could not insert a bundle (of type `bevy_window:🪟:ClosingWindow`) for entity 0v1#4294967296 because it doesn't exist in this World. See: https://bevyengine.org/learn/errors/b0003
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Encountered a panic when applying buffers for system `bevy_window::system::close_when_requested`!

Encountered a panic in system `bevy_app::main_schedule::Main::run_main`!
error: process didn't exit successfully: `target\debug\bevy.exe` (exit code: 101)
```
## Solution
Don't panic when trying to insert the `ClosingWindow` component into a
entity.
## Testing
Found and tested on windows. I haven't checked if this bug happens on
linux or macos.
For testing I ran this code:
```rust
use std::{thread, time::Duration};
use bevy::prelude::*;
fn lag() {
thread::sleep(Duration::from_millis(300));
}
fn main() -> AppExit {
App::new()
.add_plugins(DefaultPlugins)
.add_systems(Update, lag)
.run()
}
```
Then spammed the window close button. The panic no longer occurs.
# Objective
The `ui_layout_system` relies on change detection to sync parent-child
relation to taffy. The children need to by synced before node removal to
avoid trying to set deleted nodes as children (due to how the different
queries collect entities). This however may leave nodes that were
removed set as children to other nodes in special cases.
Fixes#11385
## Solution
The solution is simply to re-sync the changed children after the nodes
are removed.
## Testing
Tested with `sickle_ui` where docking zone highlights would end up
glitched when docking was done in a certain manner:
- run the `docking_zone_splits` example
- pop out a tab from the top
- dock the floating panel in the center right
- grab another tab and try to hover the original static docking zone:
the highlight is semi-stuck
- (NOTE: sometimes it worked even without the fix due to scheduling
order not producing the bugged query results)
After the fix, the issue is no longer present.
NOTE: The performance impact should be minimal, as the child sync relies
on change detection. The change detection was also the reason the parent
nodes remained "stuck" with the phantom children if no other update were
done to them.
# Objective
- `bevy_render` depends on `image 0.25` but uses `image::ImageReader`
which was added only in `image 0.25.2`
- users that have `image 0.25` in their `Cargo.lock` and update to the
latest `bevy_render` may thus get a compilation due to this (at least I
did)
## Solution
- Properly set the correct minimum version of `image` that `bevy_render`
depends on.
# Objective
Fix a memory leak in `TextureCache` caused by the internal HashMap never
having unused entries cleared.
This isn't a giant memory leak, given the unused entries are simply
empty vectors. Though, if someone goes and resizes a window a bunch, it
can lead to hundreds/thousands of TextureDescriptor keys adding up in
the hashmap – which isn't ideal.
## Solution
- Only retain hashmap entries that still have textures.
- I also added an `is_empty()` method to `TextureCache`, which is useful
for 3rd-party higher-level caches that might have individual caches by
view entity or texture type, for example.
## Testing
- Verified the examples still work (this is a trivial change)
# Objective
- `bevy_winit` fails to build with just the `serialize` feature.
- Caught by [`flag-frenzy`](https://github.com/TheBevyFlock/flag-frenzy)
in [this
run](https://github.com/TheBevyFlock/flag-frenzy/actions/runs/10087486444/job/27891723948),
using the new, nuanced configuration system!
## Solution
- It was failing because `bevy_winit` did not pass the `serialize` flag
to two of its dependencies: `bevy_input` and `bevy_window`.
- To fix this, add these crates to the feature flag.
## Testing
```bash
# On Linux, you must also specify a backend: `x11` or `wayland`.
# You can do this with `-F serialize,x11`, etc.
cargo check -p bevy_winit --no-default-features -F serialize
```
# Objective
- Fix a confusing panic when the viewport width is non-zero and the
height is 0, `prepare_bloom_textures` tries to create a `4294967295x1`
texture.
## Solution
- Avoid dividing by zero
- Apps still crash after this, but now on a more reasonable error about
the zero-size viewport
## Testing
- I isolated and tested the math. A height of 0 sets `mip_height_ratio`
to `inf`, causing the width to explode if it isn't also 0
# Objective
- `bevy_gltf` does not build with only the
`pbr_multi_layer_material_textures` or `pbr_anisotropy_texture`
features.
- Caught by [`flag-frenzy`](https://github.com/TheBevyFlock/flag-frenzy)
in [this
run](https://github.com/TheBevyFlock/flag-frenzy/actions/runs/10087486444/job/27891723948).
## Solution
- This error was due to the feature not enabling the corresponding
feature in `bevy_pbr`. Adding these flags as a dependency fixes this
error.
## Testing
The following commands fail on `main`, but pass with this PR:
```bash
cargo check -p bevy_gltf --no-default-features -F pbr_multi_layer_material_textures
cargo check -p bevy_gltf --no-default-features -F pbr_anisotropy_texture
```
# Objective
- Some types are missing reflection attributes, which means we can't use
them in scene serialization etc.
- Effected types
- `BorderRadius`
- `AnimationTransitions`
- `OnAdd`
- `OnInsert`
- `OnRemove`
- My use-case for `OnAdd` etc to derive reflect is 'Serializable
Observer Components'. Add the component, save the scene, then the
observer is re-added on scene load.
```rust
#[derive(Reflect)]
struct MySerializeableObserver<T: Event>(#[reflect(ignore)]PhantomData<T>);
impl<T: Event> Component for MySerializeableObserver<T> {
const STORAGE_TYPE: StorageType = StorageType::Table;
fn register_component_hooks(hooks: &mut ComponentHooks) {
hooks.on_add(|mut world, entity, _| {
world
.commands()
.entity(entity)
.observe(|_trigger: Trigger<T>| {
println!("it triggered etc.");
});
});
}
}
```
## Solution
- Add the missing traits
---
# Objective
- Building bevy_gltf with feature dds fails:
```

```
- If you're fixing a specific issue, say "Fixes #X".
## Solution
- enable dds feature in bevy_core_pipeline
## Testing
- `cargo build -p bevy_gltf --features dds`
# Objective
- The current default viewport crashes bevy due to a wgpu validation
error, this PR fixes that
- Fixes https://github.com/bevyengine/bevy/issues/14355
## Solution
- `Viewport::default()` now returns a 1x1 viewport
## Testing
- I modified the `3d_viewport_to_world` example to use
`Viewport::default()`, and it works as expected (only the top-left pixel
is rendered)
# Objective
- Actually use the value assigned to `d_xz`, like in [the original SMAA
implementation](https://github.com/iryoku/smaa/blob/master/SMAA.hlsl#L960).
This not already being the case was likely a mistake when converting
from HLSL to WGSL
## Solution
- Use `d_xz.x` and `d_xz.y` instead of `d.x` and `d.z`
## Testing
- Quickly tested on Windows 11, `x86_64-pc-windows-gnu` `1.79.0` with
the latest NVIDIA drivers. App runs with SMAA enabled and everything
seems to work as intended
- I didn't observe any major visual difference between this and the
previous version, though this should be more correct as it matches the
original SMAA implementation
# Objective
- [`flag-frenzy`](https://github.com/TheBevyFlock/flag-frenzy) found an
issue where `bevy_window` would fail to build when its `serialize`
feature is enabled.
- See
[here](https://github.com/TheBevyFlock/flag-frenzy/actions/runs/9924187577/job/27415224405)
for the specific log.
## Solution
- Turns out it was failing because the `bevy_ecs/serialize` feature was
not enabled. This error can be fixed by adding the flag as a dependency.
## Testing
```bash
cargo check -p bevy_window -F serialize
# Or if you're very cool...
flag-frenzy --manifest-path path/to/bevy/Cargo.toml --config config -p bevy_window
```
# Objective
- Fixes overflow when calling `RenderLayers::iter_layers` on layers of
the form `k * 64 - 1`
- Causes a panic in debug mode, and an infinite iterator in release mode
## Solution
- Use `u64::checked_shr` instead of `>>=`
## Testing
- Added a test case for this: `render_layer_iter_no_overflow`
Fixes https://github.com/bevyengine/bevy/issues/14157
- Update the ObserverSystem traits to accept an `Out` parameter
- Added a test where an observer system has a non-empty output which is
piped into another system

# Objective
With an unlucky denormalised quaternion (or just a regular very
denormalised quaternion), it's possible to obtain NaN values for AABB's
in shapes which rely on an AABB for a disk.
## Solution
Add an additional `.max(Vec3::ZERO)` clamp to get rid of negative values
arising due to numerical errors.
Fixup some unnecessary calculations and improve variable names in
relevant code, aiming for consistency.
## Discussion
These two (nontrivial) lines of code are repeated at least 5 times,
maybe they could be their own method.
Allow use of `bevy_input` types without needing `bevy_reflect`.
Make `bevy_reflect` within `bevy_input` optional. It's compiled in by
default.
Turn on reflect in dependencies as well when this feature is on.
- Did you test these changes? If so, how?
I did a `cargo hack -p bevy_input --each-feature build`.

Fix#14146
## Solution
Expansion of #13323 , excluded Adreno 730 and earlier.
## Testing
Tested on android device(Adreno 730) that used to crash
# Objective
- There was a new warning added about having an unstyled child in the ui
hierarchy. Debugging the new error is pretty hard without any info about
which entity is.
## Solution
- Add the entity id to the warning.
```text
// Before
2024-07-05T19:40:59.904014Z WARN bevy_ui::layout::ui_surface: Unstyled child in a UI entity hierarchy. You are using an entity without UI components as a child of an entity with UI components, results may be unexpected.
//After

```
## Changelog
- add entity id to ui surface warning
# Objective
- Expand the flexibilty of StateScoped by adding Reflect and Clone
- This lets StateScoped be used in Clone Bundles, for example
```rust
#[derive(Component, Reflect, Clone)]
pub struct StateScoped<S: States>(pub S);
```
Notes:
- States are already Clone.
- Type registration is up to the user, but this is commonly the case
with reflected generic types.
## Testing
- Ran the examples.
# Objective
- `EmptyPathStream` is only used in android and wasm32
- This now makes rust nightly warn
## Solution
- flag the struct to only be present when needed
- also change how `MorphTargetNames` is used because that makes rust
happier?
# Objective
- Standard Material is starting to run out of samplers (currently uses
13 with no additional features off, I think in 0.13 it was 12).
- This change adds a new feature switch, modelled on the other ones
which add features to Standard Material, to turn off the new anisotropy
feature by default.
## Solution
- feature + texture define
## Testing
- Anisotropy example still works fine
- Other samples work fine
- Standard Material now takes 12 samplers by default on my Mac instead
of 13
## Migration Guide
- Add feature pbr_anisotropy_texture if you are using that texture in
any standard materials.

# Objective
The Bevy API around manipulating hierarchies removes `Children` if the
operation results in an entity having no children. This means that
`Children` is guaranteed to hold actual children. However, the following
code unexpectedly inserts empty `Children`:
```rust
commands.entity(entity).with_children(|_| {});
```
This was discovered by @Jondolf:
https://discord.com/channels/691052431525675048/1124043933886976171/1257660865625325800
## Solution
- `with_children` is now a noop when no children were passed
## Testing
- Added a regression test
# Objective
It's not always obvious what the default value for `RenderLayers`
represents. It is documented, but since it's an implementation of a
trait method the documentation may or may not be shown depending on the
IDE.
## Solution
Add documentation to the `none` method that explicitly calls out the
difference.

# Objective
Allow combining render layers with a more-ergonomic syntax than
`RenderLayers::from_iter(a.iter().chain(b.iter()))`.
## Solution
Add the `or` operation (and corresponding `const` method) to allow
computing the union of a set of render layers. While we're here, also
added `and` and `xor` operations. Someone might find them useful
## Testing
Added a simple unit test.
# Objective
- When no wgpu backend is selected, there should be a clear explanation.
- Fix a regression in 0.14 when not using default features. I hit this
compile failure when trying to build bevy_framepace for 0.14.0-rc.4

| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
```
## Solution
- Ensure that `DEPTH_TEXTURE_SAMPLING_SUPPORTED` is either `true` or
`false`, it shouldn't be completely missing.
## Testing
- Building on WASM without default features, which now seemingly no
longer includes webgl, will panic on startup with a message saying that
no wgpu backend was selected. This is much more helpful than the compile
time failure:
```
No wgpu backend feature that is implemented for the target platform was enabled
```
- I can see an argument for making this a compile time failure, however
the current failure mode is very confusing for novice users, and
provides no clues for how to fix it. If we want this to fail at compile
time, we should do it in a way that fails with a helpful message,
similar to what this PR acheives.
# Objective
- Fixes#14059
- `morphed_skinned_mesh_layout` is the same as
`morphed_skinned_motion_mesh_layout` but shouldn't have the skin / morph
from previous frame, as they're used for motion
## Solution
- Remove the extra entries
## Testing
- Run with the glTF file reproducing #14059, it works
# Objective
- Fixes a correctness error introduced in
https://github.com/bevyengine/bevy/pull/14013 ...
## Solution
I've been playing around a lot of with the access code and I realized
that I introduced a soundness error when trying to simplify the code.
When we have a `Or<(With<A>, With<B>)>` filter, we cannot call
```
let mut intermediate = FilteredAccess::default();
$name::update_component_access($name, &mut intermediate);
_new_access.append_or(&intermediate);
```
because that's just equivalent to adding the new components as `Or`
clauses.
For example if the existing `filter_sets` was `vec![With<C>]`, we would
then get `vec![With<C>, With<A>, With<B>]` which translates to `A or B
or C`.
Instead what we want is `(A and B) or (A and C)`, so we need to have
each new OR clause compose with the existing access like so:
```
let mut intermediate = _access.clone();
// if we previously had a With<C> in the filter_set, this will become `With<C> AND With<A>`
$name::update_component_access($name, &mut intermediate);
_new_access.append_or(&intermediate);
```
## Testing
- Added a unit test that is broken in main, but passes in this PR
# Objective
`sickle_ui` needs `PartialEq` on components to turn them into animatable
style attributes.
## Solution
All properties of Outline is already `PartialEq`, add derive on
`Outline` as well.
## Testing
- used `sickle_ui` to test if it can be made animatable
As reported in #14004, many third-party plugins, such as Hanabi, enqueue
entities that don't have meshes into render phases. However, the
introduction of indirect mode added a dependency on mesh-specific data,
breaking this workflow. This is because GPU preprocessing requires that
the render phases manage indirect draw parameters, which don't apply to
objects that aren't meshes. The existing code skips over binned entities
that don't have indirect draw parameters, which causes the rendering to
be skipped for such objects.
To support this workflow, this commit adds a new field,
`non_mesh_items`, to `BinnedRenderPhase`. This field contains a simple
list of (bin key, entity) pairs. After drawing batchable and unbatchable
objects, the non-mesh items are drawn one after another. Bevy itself
doesn't enqueue any items into this list; it exists solely for the
application and/or plugins to use.
Additionally, this commit switches the asset ID in the standard bin keys
to be an untyped asset ID rather than that of a mesh. This allows more
flexibility, allowing bins to be keyed off any type of asset.
This patch adds a new example, `custom_phase_item`, which simultaneously
serves to demonstrate how to use this new feature and to act as a
regression test so this doesn't break again.
Fixes#14004.
## Changelog
### Added
* `BinnedRenderPhase` now contains a `non_mesh_items` field for plugins
to add custom items to.
# Objective
`StaticSystemParam` should delegate all `SystemParam` methods to the
inner param, but it looks like it was missed when the new `queue()`
method was added in #10839.
## Solution
Implement `StaticSystemParam::queue()` to delegate to the inner param.
