Fixes#13479
This also fixes the gaps you can sometimes observe in outlines
(screenshot from main, not this PR):

The outline around the last item in each section has vertical gaps.
Draw the outlines with corner radius using the existing border rendering
for uinodes. The outline radius is very simple to calculate. We just
take the computed border radius of the node, and if it's greater than
zero, add it to the distance from the edge of the node to the outer edge
of the node's outline.

# Objective
Fixes#15032
## Solution
Reimplement support for the `flip_x` and `flip_y` fields.
This doesn't flip the border geometry, I'm not really sure whether that
is desirable or not.
Also fixes a bug that was causing the side and center slices to tile
incorrectly.
### Testing
```
cargo run --example ui_texture_slice_flip_and_tile
```

Fixes https://github.com/bevyengine/bevy/issues/14183
Reimplement the UI texture atlas slicer using a shader.
The problems with #14183 could be fixed more simply by hacking around
with the coordinates and scaling but that way is very fragile and might
get broken again the next time we make changes to the layout
calculations. A shader based solution is more robust, it's impossible
for gaps to appear between the image slices with these changes as we're
only drawing a single quad.
I've not tried any benchmarks yet but it should much more efficient as
well, in the worst cases even hundreds or thousands of times faster.
Maybe could have used the UiMaterialPipeline. I wrote the shader first
and used fat vertices and then realised it wouldn't work that way with a
UiMaterial. If it's rewritten it so it puts all the slice geometry in
uniform buffer, then it might work? Adding the uniform buffer would
probably make the shader more complicated though, so don't know if it's
even worth it. Instancing is another alternative.
The examples are working and it seems to match the old API correctly but
I've not used the texture atlas slicing API for anything before, I
reviewed the PR but that was back in January.
Needs a review by someone who knows the rendering pipeline and wgsl
really well because I don't really have any idea what I'm doing.
`resolve_outlines_system` wasn't updated when multi-window support was
added and it always uses the size of the primary window when resolving
viewport coords, regardless of the layout's camera target.
Fixes#14945
It's awkward to get the viewport size of the target for an individual
node without walking the tree or adding extra fields to `Node`, so I
removed `resolve_outlines_system` and instead the outline values are
updated in `ui_layout_system`.

# Objective
- Gizmo rendering on WebGPU has been fixed by #14653, but gizmo joints
still cause error
(https://github.com/bevyengine/bevy/issues/14696#issuecomment-2283689669)
when enabled.
## Solution
- Applies the same fix as #14653 to Gizmo joints.
I'm noob and just copied their solution, please correct me if I did
something wrong.
## Testing
- Tested 2d-gizmos and 3d-gizmos examples in WebGPU on Chrome. No
rendering errors, and the gizmo joints are apparently rendered ok.
# Objective
Fixes Commands not being `Send` or `Sync` anymore in 0.14 by
implementing `Send` and `Sync` for `RawCommandQueue`.
## Solution
Reference discussion in
[discord](https://discord.com/channels/691052431525675048/691052431974465548/1259464518539411570).
It seems that in https://github.com/bevyengine/bevy/pull/13249, when
adding a `RawCommandQueue` variant to the `InternalQueue`, the `Send /
Sync` traits were not implemented for it, which bubbled up all the way
to `Commands` not being `Send / Sync` anymore.
I am not very familiar with the ECS internals so I can't say whether the
`RawCommandQueue` is safe to be shared between threads, but I know for
sure that before the linked PR `Commands` were indeed `Send` and `Sync`
so that PR broke "some workflows" (mandatory
[xkcd](https://xkcd.com/1172/)).
## Testing
This PR itself includes a compile test to make sure `Commands` will
implement `Send` and `Sync`. The test itself fails without the
implementation and succeeds with it.
Furthermore, if I cherry pick the test to a previous release (i.e. 0.13)
it indeed succeeds, showing that this is a regression specific to 0.14.

# Objective
fix#14742
## Solution
the issue arises because "finished" animations (where current time >=
last keyframe time) are not applied at all.
when transitioning from a finished animation to another later-indexed
anim, the transition kind-of works because the finished anim is skipped,
then the new anim is applied with a lower weight (weight / total_weight)
when transitioning from a finished animation to another earlier-indexed
anim, the transition is instant as the new anim is applied with 1.0 (as
weight == total_weight for the first applied), then the finished
animation is skipped.
to fix this we can always apply every animation based on the nearest 2
keyframes, and clamp the interpolation between them to [0,1].
pros:
- finished animations can be transitioned out of correctly
- blended animations where some curves have a last-keyframe before the
end of the animation will blend properly
- animations will actually finish on their last keyframe, rather than a
fraction of a render-frame before the end
cons:
- we have to re-apply finished animations every frame whether it's
necessary or not. i can't see a way to avoid this.
# Objective
- Right now `DynamicEnum::is_dynamic()` is returning `false`. I don't
think this was expected, since the rest of `Dynamic*` types return
`true`.
## Solution
- Making `DynamicEnum::is_dynamic()` return true
## Testing
- Added an extra unit test to verify that `.is_dynamic()` returns
`true`.
# Objective
The changes made in https://github.com/bevyengine/bevy/pull/12252
introduced an previously fixed bug in webgpu rendering.
## Solution
This fix is based on https://github.com/bevyengine/bevy/pull/8910 and
applies the same vertex buffer layout assignment for the LineGizmo
Pipeline.
## Testing
- Tested the 3D Gizmo example in webgpu and webgl environments
Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com>
# Objective
Closes#14526
## Solution
The history texture was being created incorrectly with the viewport size
rather than target size. When viewport < target, this meant that the
render attachments would differer in size which causes a wgpu validation
error.
## Testing
Example in linked issue works.
Fixes https://github.com/bevyengine/bevy/issues/14277.
May also fix https://github.com/bevyengine/bevy/issues/14255, needs
verification.
Explicitly order `CameraUpdateSystem` before `UiSystem::Prepare`, so
that when the window resizes, `camera_system` will update the `Camera`'s
viewport size before `ui_layout_system` also reacts to the window resize
and tries to read the new `Camera` viewport size to set UI node sizes
accordingly.
I tested that explicitly ordering `CameraUpdateSystem` _after_ triggers
the buggy behavior, and explicitly ordering it _before_ does not trigger
the buggy behavior or crash the app (which also demonstrates that the
system sets are ambiguous).
---
`CameraUpdateSystem` is now explicitly ordered before
`UiSystem::Prepare` instead of being ambiguous with it.
# Objective
While scrolling through the animation crate, I was confused by the docs
and code for the two methods. One does nothing for resetting an
animation, the other just resets the weights for whatever reason.
## Solution
Made the functions work accordingly to their documentation.
`start` now replays the animation.
And `play` doesn't reset the weight anymore. I have no clue why it
should. `play` is there to don't do anything to an already existing
animation.
## Testing
I tested the current 0.14 code with bevy playground in the Animated Fox
exampled and changed it such that on pressing space, either `play` or
`start` would be called. Neither changed anything.
I then inlined the function for start there and it restarted the
animation, so it should work.
---
## Migration Guide
`AnimationPlayer::start` now correspondingly to its docs restarts a
running animation.
`AnimationPlayer::play` doesn't reset the weight anymore.
# Objective
Fix erroneous hue mixing in `Lcha` and `Oklcha`. Purple + Red == Green
is the current behavior.
## Solution
Use `crate::color_ops::lerp_hue` to handle the wrap-around at 360
degrees, the same way that `Hsla`, `Hsva`, and `Hwba` do it.
## Testing
Game jamming, but tested that the workaround below produces
correct-looking colors in my jam game.
# Objective
Fixes#13910
When a transition is over, the animation is stopped. There was a race
condition; if an animation was started while it also had an active
transition, the transition ending would then incorrectly stop the newly
added animation.
## Solution
When starting an animation, cancel any previous transition for the same
animation.
## Testing
The changes were tested manually, mainly by using the `animated_fox`
example. I also tested with changes from
https://github.com/bevyengine/bevy/pull/13909.
I'd like to have an unit test for this as well, but it seems quite
complex to do, as I'm not sure how I would detect an incorrectly paused
animation.
Reviewers can follow the instructions in #13910 to reproduce.
Tested on macos 14.4 (M3 processor) Should be platform-independent,
though.
# Objective
When the user renders multiple cameras to the same output texture, it
can sometimes be confusing what `ClearColorConfig` is necessary for each
camera to avoid overwriting the previous camera's output. This is
particular true in cases where the user uses mixed HDR cameras, which
means that their scene is being rendered to different internal textures.
## Solution
When a view has a configured viewport, set the GPU scissor in the
upscaling node so we don't overwrite areas that were written to by other
cameras.
## Testing
Ran the `split_screen` example.
# 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`.

## 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
- 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

# 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

## 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

## 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`.
