# Objective
Continue improving the user experience of our UI Node API in the
direction specified by [Bevy's Next Generation Scene / UI
System](https://github.com/bevyengine/bevy/discussions/14437)
## Solution
As specified in the document above, merge `Style` fields into `Node`,
and move "computed Node fields" into `ComputedNode` (I chose this name
over something like `ComputedNodeLayout` because it currently contains
more than just layout info. If we want to break this up / rename these
concepts, lets do that in a separate PR). `Style` has been removed.
This accomplishes a number of goals:
## Ergonomics wins
Specifying both `Node` and `Style` is now no longer required for
non-default styles
Before:
```rust
commands.spawn((
Node::default(),
Style {
width: Val::Px(100.),
..default()
},
));
```
After:
```rust
commands.spawn(Node {
width: Val::Px(100.),
..default()
});
```
## Conceptual clarity
`Style` was never a comprehensive "style sheet". It only defined "core"
style properties that all `Nodes` shared. Any "styled property" that
couldn't fit that mold had to be in a separate component. A "real" style
system would style properties _across_ components (`Node`, `Button`,
etc). We have plans to build a true style system (see the doc linked
above).
By moving the `Style` fields to `Node`, we fully embrace `Node` as the
driving concept and remove the "style system" confusion.
## Next Steps
* Consider identifying and splitting out "style properties that aren't
core to Node". This should not happen for Bevy 0.15.
---
## Migration Guide
Move any fields set on `Style` into `Node` and replace all `Style`
component usage with `Node`.
Before:
```rust
commands.spawn((
Node::default(),
Style {
width: Val::Px(100.),
..default()
},
));
```
After:
```rust
commands.spawn(Node {
width: Val::Px(100.),
..default()
});
```
For any usage of the "computed node properties" that used to live on
`Node`, use `ComputedNode` instead:
Before:
```rust
fn system(nodes: Query<&Node>) {
for node in &nodes {
let computed_size = node.size();
}
}
```
After:
```rust
fn system(computed_nodes: Query<&ComputedNode>) {
for computed_node in &computed_nodes {
let computed_size = computed_node.size();
}
}
```
# Objective
As discussed in #15341, ghost nodes are a contentious and experimental
feature. In the interest of enabling ecosystem experimentation, we've
decided to keep them in Bevy 0.15.
That said, we don't use them internally, and don't expect third-party
crates to support them. If the experimentation returns a negative result
(they aren't very useful, an alternative design is preferred etc) they
will be removed.
We should clearly communicate this status to users, and make sure that
users don't use ghost nodes in their projects without a very clear
understanding of what they're getting themselves into.
## Solution
To make life easy for users (and Bevy), `GhostNode` and all associated
helpers remain public and are always available.
However, actually constructing these requires enabling a feature flag
that's clearly marked as experimental. To do so, I've added a
meaningless private field.
When the feature flag is enabled, our constructs (`new` and `default`)
can be used. I've added a `new` constructor, which should be preferred
over `Default::default` as that can be readily deprecated, allowing us
to prompt users to swap over to the much nicer `GhostNode` syntax once
this is a unit struct again.
Full credit: this was mostly @cart's design: I'm just implementing it!
## Testing
I've run the ghost_nodes example and it fails to compile without the
feature flag. With the feature flag, it works fine :)

Fixes#15834
## Migration Guide
The APIs of `Time`, `Timer` and `Stopwatch` have been cleaned up for
consistency with each other and the standard library's `Duration` type.
The following methods have been renamed:
- `Stowatch::paused` -> `Stopwatch::is_paused`
- `Time::elapsed_seconds` -> `Time::elasped_secs` (including `_f64` and
`_wrapped` variants)
# Objective
Limited implementation of the CSS property `overflow-clip-margin`
https://developer.mozilla.org/en-US/docs/Web/CSS/overflow-clip-margin
Allows you to control the visible area for clipped content when using
overfllow-clip, -hidden, or -scroll and expand it with a margin.
Based on #15442Fixes#15468
## Solution
Adds a new field to Style: `overflow_clip_margin: OverflowClipMargin`.
The field is ignored unless overflow-clip, -hidden or -scroll is set on
at least one axis.
`OverflowClipMargin` has these associated constructor functions:
```
pub const fn content_box() -> Self;
pub const fn padding_box() -> Self;
pub const fn border_box() -> Self;
```
You can also use the method `with_margin` to increases the size of the
visible area:
```
commands
.spawn(NodeBundle {
style: Style {
width: Val::Px(100.),
height: Val::Px(100.),
padding: UiRect::all(Val::Px(20.)),
border: UiRect::all(Val::Px(5.)),
overflow: Overflow::clip(),
overflow_clip_margin: OverflowClipMargin::border_box().with_margin(25.),
..Default::default()
},
border_color: Color::BLACK.into(),
background_color: GRAY.into(),
..Default::default()
})
```
`with_margin` expects a length in logical pixels, negative values are
clamped to zero.
## Notes
* To keep this PR as simple as possible I omitted responsive margin
values support. This could be added in a follow up if we want it.
* CSS also supports a `margin-box` option but we don't have access to
the margin values in `Node` so it's probably not feasible to implement
atm.
## Testing
```cargo run --example overflow_clip_margin```
<img width="396" alt="overflow-clip-margin" src="https://github.com/user-attachments/assets/07b51cd6-a565-4451-87a0-fa079429b04b">
## Migration Guide
Style has a new field `OverflowClipMargin`. It allows users to set the visible area for clipped content when using overflow-clip, -hidden, or -scroll and expand it with a margin.
There are three associated constructor functions `content_box`, `padding_box` and `border_box`:
* `content_box`: elements painted outside of the content box area (the innermost part of the node excluding the padding and border) of the node are clipped. This is the new default behaviour.
* `padding_box`: elements painted outside outside of the padding area of the node are clipped.
* `border_box`: elements painted outside of the bounds of the node are clipped. This matches the behaviour from Bevy 0.14.
There is also a `with_margin` method that increases the size of the visible area by the given number in logical pixels, negative margin values are clamped to zero.
`OverflowClipMargin` is ignored unless overflow-clip, -hidden or -scroll is also set on at least one axis of the UI node.

# Objective
Cleanup naming and docs, add missing migration guide after #15591
All text root nodes now use `Text` (UI) / `Text2d`.
All text readers/writers use `Text<Type>Reader`/`Text<Type>Writer`
convention.
---
## Migration Guide
Doubles as #15591 migration guide.
Text bundles (`TextBundle` and `Text2dBundle`) were removed in favor of
`Text` and `Text2d`.
Shared configuration fields were replaced with `TextLayout`, `TextFont`
and `TextColor` components.
Just `TextBundle`'s additional field turned into `TextNodeFlags`
component,
while `Text2dBundle`'s additional fields turned into `TextBounds` and
`Anchor` components.
Text sections were removed in favor of hierarchy-based approach.
For root text entities with `Text` or `Text2d` components, child
entities with `TextSpan` will act as additional text sections.
To still access text spans by index, use the new `TextUiReader`,
`Text2dReader` and `TextUiWriter`, `Text2dWriter` system parameters.
# Objective
Change UI clipping to respect borders and padding.
Fixes#15335
## Solution
Based on #15163
1. Add a `padding` field to `Node`.
2. In `ui_layout_size` copy the padding values from taffy to
`Node::padding`.
4. Determine the node's content box (The innermost part of the node
excluding the padding and border).
5. In `update_clipping` perform the clipping intersection with the
node's content box.
## Notes
* `Rect` probably needs some helper methods for working with insets but
because `Rect` and `BorderRect` are in different crates it's awkward to
add them. Left for a follow up.
* We could have another `Overflow` variant (probably called
`Overflow::Hidden`) to that clips inside of the border box instead of
the content box. Left it out here as I'm not certain about the naming or
behaviour though. If this PR is adopted, it would be trivial to add a
`Hidden` variant in a follow up.
* Depending on UI scaling there are sometimes gaps in the layout:
<img width="532" alt="rounding-bug"
src="https://github.com/user-attachments/assets/cc29aa0d-44fe-403f-8f0e-cd28a8b1d1b3">
This is caused by existing bugs in `ui_layout_system`'s coordinates
rounding and not anything to do with the changes in this PR.
## Testing
This PR also changes the `overflow` example to display borders on the
overflow nodes so you can see how this works:
#### main (The image is clipped at the edges of the node, overwriting
the border).

# Objective
- closes#15866
## Solution
- Simply migrate where possible.
## Testing
- Expect that CI will do most of the work. Examples is another way of
testing this, as most of the work is in that area.
---
## Notes
For now, this PR doesn't migrate `QueryState::single` and friends as for
now, this look like another issue. So for example, QueryBuilders that
used single or `World::query` that used single wasn't migrated. If there
is a easy way to migrate those, please let me know.
Most of the uses of `Query::single` were removed, the only other uses
that I found was related to tests of said methods, so will probably be
removed when we remove `Query::single`.
# Objective
Currently text is recomputed unnecessarily on any changes to its color,
which is extremely expensive.
## Solution
Split up `TextStyle` into two separate components `TextFont` and
`TextColor`.
## Testing
I added this system to `many_buttons`:
```rust
fn set_text_colors_changed(mut colors: Query<&mut TextColor>) {
for mut text_color in colors.iter_mut() {
text_color.set_changed();
}
}
```
reports ~4fps on main, ~50fps with this PR.
## Migration Guide
`TextStyle` has been renamed to `TextFont` and its `color` field has
been moved to a separate component named `TextColor` which newtypes
`Color`.
**Ready for review. Examples migration progress: 100%.**
# Objective
- Implement https://github.com/bevyengine/bevy/discussions/15014
## Solution
This implements [cart's
proposal](https://github.com/bevyengine/bevy/discussions/15014#discussioncomment-10574459)
faithfully except for one change. I separated `TextSpan` from
`TextSpan2d` because `TextSpan` needs to require the `GhostNode`
component, which is a `bevy_ui` component only usable by UI.
Extra changes:
- Added `EntityCommands::commands_mut` that returns a mutable reference.
This is a blocker for extension methods that return something other than
`self`. Note that `sickle_ui`'s `UiBuilder::commands` returns a mutable
reference for this reason.
## Testing
- [x] Text examples all work.

## Showcase
TODO: showcase-worthy
## Migration Guide
TODO: very breaking
### Accessing text spans by index
Text sections are now text sections on different entities in a
hierarchy, Use the new `TextReader` and `TextWriter` system parameters
to access spans by index.
Before:
```rust
fn refresh_text(mut query: Query<&mut Text, With<TimeText>>, time: Res<Time>) {
let text = query.single_mut();
text.sections[1].value = format_time(time.elapsed());
}
```
After:
```rust
fn refresh_text(
query: Query<Entity, With<TimeText>>,
mut writer: UiTextWriter,
time: Res<Time>
) {
let entity = query.single();
*writer.text(entity, 1) = format_time(time.elapsed());
}
```
### Iterating text spans
Text spans are now entities in a hierarchy, so the new `UiTextReader`
and `UiTextWriter` system parameters provide ways to iterate that
hierarchy. The `UiTextReader::iter` method will give you a normal
iterator over spans, and `UiTextWriter::for_each` lets you visit each of
the spans.

# Objective
- Closes#15720
## Solution
Wrap the handle in a new wrapper component: `UiMaterialHandle`
It's not possible to match the naming convention of `MeshMaterial3d/2d`
here with the trait already being called `UiMaterial`
Should we consider renaming to `Material3d/2dHandle` and `Mesh3d/2d` to
`Mesh3d/2dHandle`?
- This shouldn't have any merge conflicts with #15591
## Testing
Tested the `ui_material` example
## Migration Guide
Let's defer the migration guide to the required component port. I just
want to yeet the `Component` impl on `Handle` in the meantime :)
# Objective
UI box shadow support
Adds a new component `BoxShadow`:
```rust
pub struct BoxShadow {
/// The shadow's color
pub color: Color,
/// Horizontal offset
pub x_offset: Val,
/// Vertical offset
pub y_offset: Val,
/// Horizontal difference in size from the occluding uninode
pub spread_radius: Val,
/// Blurriness of the shadow
pub blur_radius: Val,
}
```
To use `BoxShadow`, add the component to any Bevy UI node and a shadow
will be drawn beneath that node.
Also adds a resource `BoxShadowSamples` that can be used to adjust the
shadow quality.
#### Notes
* I'm not super happy with the field names. Maybe we need a `struct Size
{ width: Val, height: Val }` type or something.
* The shader isn't very optimised but I don't see that it's too
important for now as the number of shadows being rendered is not going
to be massive most of the time. I think it's more important to get the
API and geometry correct with this PR.
* I didn't implement an inset property, it's not essential and can
easily be added in a follow up.
* Shadows are only rendered for uinodes, not for images or text.
* Batching isn't supported, it would need out-of-the-scope-of-this-pr
changes to the way the UI handles z-ordering for it to be effective.

- Rename `Pickable` to `PickingBehavior` to counter the easily-made

text node, making it much more obvious that there is a bug causing the
size of the bounds to be calculated incorrectly.
# Objective
Yet another PR for migrating stuff to required components. This time,
cameras!
## Solution
As per the [selected
proposal](https://hackmd.io/tsYID4CGRiWxzsgawzxG_g#Combined-Proposal-1-Selected),
deprecate `Camera2dBundle` and `Camera3dBundle` in favor of `Camera2d`
and `Camera3d`.
Adding a `Camera` without `Camera2d` or `Camera3d` now logs a warning,
as suggested by Cart [on
Discord](https://discord.com/channels/691052431525675048/1264881140007702558/1291506402832945273).
I would personally like cameras to work a bit differently and be split
into a few more components, to avoid some footguns and confusing
semantics, but that is more controversial, and shouldn't block this core
migration.
## Testing
I ran a few 2D and 3D examples, and tried cameras with and without
render graphs.
---
## Migration Guide
`Camera2dBundle` and `Camera3dBundle` have been deprecated in favor of
`Camera2d` and `Camera3d`. Inserting them will now also insert the other
components required by them automatically.
# Objective
- Fixes#14826
- For context, see #15238
## Solution
Add a `GhostNode` component to `bevy_ui` and update all the relevant
systems to use it to traverse for UI children.
- [x] `ghost_hierarchy` module
- [x] Add `GhostNode`
- [x] Add `UiRootNodes` system param for iterating (ghost-aware) UI root
nodes
- [x] Add `UiChildren` system param for iterating (ghost-aware) UI
children
- [x] Update `layout::ui_layout_system`
- [x] Use ghost-aware root nodes for camera updates
- [x] Update and remove children in taffy
- [x] Initial spawn
- [x] Detect changes on nested UI children
- [x] Use ghost-aware children traversal in
`update_uinode_geometry_recursive`
- [x] Update the rest of the UI systems to use the ghost hierarchy
- [x] `stack::ui_stack_system`
- [x] `update::`
- [x] `update_clipping_system`
- [x] `update_target_camera_system`
- [x] `accessibility::calc_name`
## Testing
- [x] Added a new example `ghost_nodes` that can be used as a testbed.
- [x] Added unit tests for _some_ of the traversal utilities in
`ghost_hierarchy`
- [x] Ensure this fulfills the needs for currently known use cases
- [x] Reactivity libraries (test with `bevy_reactor`)
- [ ] Text spans (mentioned by koe [on
discord](https://discord.com/channels/691052431525675048/1285371432460881991/1285377442998915246))
---
## Performance
[See comment
below](https://github.com/bevyengine/bevy/pull/15341#issuecomment-2385456820)
## Migration guide
Any code that previously relied on `Parent`/`Children` to iterate UI
children may now want to use `bevy_ui::UiChildren` to ensure ghost nodes
are skipped, and their first descendant Nodes included.
UI root nodes may now be children of ghost nodes, which means
`Without<Parent>` might not query all root nodes. Use
`bevy_ui::UiRootNodes` where needed to iterate root nodes instead.
## Potential future work
- Benchmarking/optimizations of hierarchies containing lots of ghost
nodes
- Further exploration of UI hierarchies and markers for root nodes/leaf
nodes to create better ergonomics for things like `UiLayer` (world-space
ui)

# Objective
- Improve code quality in preparation for
https://github.com/bevyengine/bevy/discussions/15014
## Solution
- Rename BreakLineOn to LineBreak.
## Migration Guide
`BreakLineOn` was renamed to `LineBreak`, and paramters named
`linebreak_behavior` were renamed to `linebreak`.
# Objective
A big step in the migration to required components: meshes and
materials!
## Solution
As per the [selected
proposal](https://hackmd.io/@bevy/required_components/%2Fj9-PnF-2QKK0on1KQ29UWQ):
- Deprecate `MaterialMesh2dBundle`, `MaterialMeshBundle`, and
`PbrBundle`.
- Add `Mesh2d` and `Mesh3d` components, which wrap a `Handle<Mesh>`.
- Add `MeshMaterial2d<M: Material2d>` and `MeshMaterial3d<M: Material>`,
which wrap a `Handle<M>`.
- Meshes *without* a mesh material should be rendered with a default
material. The existence of a material is determined by
`HasMaterial2d`/`HasMaterial3d`, which is required by
`MeshMaterial2d`/`MeshMaterial3d`. This gets around problems with the
generics.
Previously:
```rust
commands.spawn(MaterialMesh2dBundle {
mesh: meshes.add(Circle::new(100.0)).into(),
material: materials.add(Color::srgb(7.5, 0.0, 7.5)),
transform: Transform::from_translation(Vec3::new(-200., 0., 0.)),
..default()
});
```
Now:
```rust
commands.spawn((
Mesh2d(meshes.add(Circle::new(100.0))),
MeshMaterial2d(materials.add(Color::srgb(7.5, 0.0, 7.5))),
Transform::from_translation(Vec3::new(-200., 0., 0.)),
));
```
If the mesh material is missing, previously nothing was rendered. Now,
it renders a white default `ColorMaterial` in 2D and a
`StandardMaterial` in 3D (this can be overridden). Below, only every
other entity has a material:
Why white? This is still open for discussion, but I think white makes
sense for a *default* material, while *invalid* asset handles pointing
to nothing should have something like a pink material to indicate that
something is broken (I don't handle that in this PR yet). This is kind
of a mix of Godot and Unity: Godot just renders a white material for
non-existent materials, while Unity renders nothing when no materials
exist, but renders pink for invalid materials. I can also change the
default material to pink if that is preferable though.
## Testing
I ran some 2D and 3D examples to test if anything changed visually. I
have not tested all examples or features yet however. If anyone wants to
test more extensively, it would be appreciated!
## Implementation Notes
- The relationship between `bevy_render` and `bevy_pbr` is weird here.
`bevy_render` needs `Mesh3d` for its own systems, but `bevy_pbr` has all
of the material logic, and `bevy_render` doesn't depend on it. I feel
like the two crates should be refactored in some way, but I think that's
out of scope for this PR.
- I didn't migrate meshlets to required components yet. That can
probably be done in a follow-up, as this is already a huge PR.
- It is becoming increasingly clear to me that we really, *really* want
to disallow raw asset handles as components. They caused me a *ton* of
headache here already, and it took me a long time to find every place
that queried for them or inserted them directly on entities, since there
were no compiler errors for it. If we don't remove the `Component`
derive, I expect raw asset handles to be a *huge* footgun for users as
we transition to wrapper components, especially as handles as components
have been the norm so far. I personally consider this to be a blocker
for 0.15: we need to migrate to wrapper components for asset handles
everywhere, and remove the `Component` derive. Also see
https://github.com/bevyengine/bevy/issues/14124.
---
## Migration Guide
Asset handles for meshes and mesh materials must now be wrapped in the
`Mesh2d` and `MeshMaterial2d` or `Mesh3d` and `MeshMaterial3d`
components for 2D and 3D respectively. Raw handles as components no
longer render meshes.
Additionally, `MaterialMesh2dBundle`, `MaterialMeshBundle`, and
`PbrBundle` have been deprecated. Instead, use the mesh and material
components directly.
Previously:
```rust
commands.spawn(MaterialMesh2dBundle {
mesh: meshes.add(Circle::new(100.0)).into(),
material: materials.add(Color::srgb(7.5, 0.0, 7.5)),
transform: Transform::from_translation(Vec3::new(-200., 0., 0.)),
..default()
});
```
Now:
```rust
commands.spawn((
Mesh2d(meshes.add(Circle::new(100.0))),
MeshMaterial2d(materials.add(Color::srgb(7.5, 0.0, 7.5))),
Transform::from_translation(Vec3::new(-200., 0., 0.)),
));
```
If the mesh material is missing, a white default material is now used.
Previously, nothing was rendered if the material was missing.
The `WithMesh2d` and `WithMesh3d` query filter type aliases have also
been removed. Simply use `With<Mesh2d>` or `With<Mesh3d>`.

# Objective
Another step in the migration to required components: lights!
Note that this does not include `EnvironmentMapLight` or reflection
probes yet, because their API hasn't been fully chosen yet.
## Solution
As per the [selected
proposals](https://hackmd.io/@bevy/required_components/%2FLLnzwz9XTxiD7i2jiUXkJg):
- Deprecate `PointLightBundle` in favor of the `PointLight` component
- Deprecate `SpotLightBundle` in favor of the `PointLight` component
- Deprecate `DirectionalLightBundle` in favor of the `DirectionalLight`
component
## Testing
I ran some examples with lights.
---
## Migration Guide
`PointLightBundle`, `SpotLightBundle`, and `DirectionalLightBundle` have
been deprecated. Use the `PointLight`, `SpotLight`, and
`DirectionalLight` components instead. Adding them will now insert the
other components required by them automatically.
# Objective
`ui_stack_system` generates a tree of `StackingContexts` which it then
flattens to get the `UiStack`.
But there's no need to construct a new tree. We can query for nodes with
a global `ZIndex`, add those nodes to the root nodes list and then build
the `UiStack` from a walk of the existing layout tree, ignoring any
branches that have a global `Zindex`.
Fixes#9877
## Solution
Split the `ZIndex` enum into two separate components, `ZIndex` and
`GlobalZIndex`
Query for nodes with a `GlobalZIndex`, add those nodes to the root nodes
list and then build the `UiStack` from a walk of the existing layout
tree, filtering branches by `Without<GlobalZIndex>` so we don't revisit
nodes.

## Changelog
`Zindex`
* The `ZIndex` enum has been split into two separate components `ZIndex`

`ZIndex::Global`). An entity can have both a `ZIndex` and
`GlobalZIndex`, in comparisons `ZIndex` breaks ties if two
`GlobalZIndex` values are equal.
`ui_stack_system`
* Instead of generating a tree of `StackingContexts`, query for nodes
with a `GlobalZIndex`, add those nodes to the root nodes list and then
build the `UiStack` from a walk of the existing layout tree, filtering
branches by `Without<GlobalZIndex` so we don't revisit nodes.
## Migration Guide
The `ZIndex` enum has been split into two separate components `ZIndex`
(which replaces `ZIndex::Local`) and `GlobalZIndex` (which replaces
`ZIndex::Global`). An entity can have both a `ZIndex` and
`GlobalZIndex`, in comparisons `ZIndex` breaks ties if two
`GlobalZindex` values are equal.

# Objective
- Fixes#6370
- Closes#6581
## Solution
- Added the following lints to the workspace:
- `std_instead_of_core`
- `std_instead_of_alloc`
- `alloc_instead_of_core`
- Used `cargo +nightly fmt` with [item level use
formatting](https://rust-lang.github.io/rustfmt/?version=v1.6.0&search=#Item%5C%3A)
to split all `use` statements into single items.
- Used `cargo clippy --workspace --all-targets --all-features --fix
--allow-dirty` to _attempt_ to resolve the new linting issues, and
intervened where the lint was unable to resolve the issue automatically
(usually due to needing an `extern crate alloc;` statement in a crate
root).
- Manually removed certain uses of `std` where negative feature gating
prevented `--all-features` from finding the offending uses.
- Used `cargo +nightly fmt` with [crate level use
formatting](https://rust-lang.github.io/rustfmt/?version=v1.6.0&search=#Crate%5C%3A)
to re-merge all `use` statements matching Bevy's previous styling.
- Manually fixed cases where the `fmt` tool could not re-merge `use`
statements due to conditional compilation attributes.
## Testing
- Ran CI locally
## Migration Guide
The MSRV is now 1.81. Please update to this version or higher.
## Notes
- This is a _massive_ change to try and push through, which is why I've
outlined the semi-automatic steps I used to create this PR, in case this
fails and someone else tries again in the future.
- Making this change has no impact on user code, but does mean Bevy
contributors will be warned to use `core` and `alloc` instead of `std`
where possible.
- This lint is a critical first step towards investigating `no_std`
options for Bevy.

# Objective
Fixes#15142
## Solution
* Moved all the UI border geometry calculations that were scattered
through the UI extraction functions into `ui_layout_system`.
* Added a `border: BorderRect` field to `Node` to store the border size
computed by `ui_layout_system`.
* Use the border values returned from Taffy rather than calculate them
ourselves during extraction.
* Removed the `logical_rect` and `physical_rect` methods from `Node` the
descriptions and namings are deceptive, it's better to create the rects
manually instead.
* Added a method `outline_radius` to `Node` that calculates the border
radius of outlines.
* For border values `ExtractedUiNode` takes `BorderRect` and
`ResolvedBorderRadius` now instead of raw `[f32; 4]` values and converts
them in `prepare_uinodes`.
* Removed some unnecessary scaling and clamping of border values
(#15142).
* Added a `BorderRect::ZERO` constant.
* Added an `outlined_node_size` method to `Node`.
## Testing
Added some non-uniform borders to the border example. Everything seems
to be in order:

## Migration Guide
The `logical_rect` and `physical_rect` methods have been removed from
`Node`. Use `Rect::from_center_size` with the translation and node size
instead.
The types of the fields border and border_radius of `ExtractedUiNode`
have been changed to `BorderRect` and `ResolvedBorderRadius`
respectively.

# Objective
Fixes#15401
## Solution
Changes the scroll inversion hotkey in the example from Shift to
Control.
Shift is idiomatic for this. Since we cannot use Shift per #15401, I
picked another modifier arbitrarily. A production app would handle this
in a platform specific way until the platform behaviors are unified
upstream, but no point here.
## Testing
I don't have a mac readily available for testing, if someone wouldn't
mind testing. I would also appreciate confirmation that trackpad is
working nicely.
# Objective
- Fixes#10720
- Adds the ability to control font smoothing of rendered text
## Solution
- Introduce the `FontSmoothing` enum, with two possible variants
(`FontSmoothing::None` and `FontSmoothing::AntiAliased`):
- This is based on `-webkit-font-smoothing`, in line with our practice
of adopting CSS-like properties/names for UI;
- I could have gone instead for the [`font-smooth`
property](https://developer.mozilla.org/en-US/docs/Web/CSS/font-smooth)
that's also supported by browsers, but didn't since it's also
non-standard, has an uglier name, and doesn't allow controlling the type
of antialias applied.
- Having an enum instead of e.g. a boolean, leaves the path open for
adding `FontSmoothing::SubpixelAntiAliased` in the future, without a
breaking change;
- Add all the necessary plumbing to get the `FontSmoothing` information
to where we rasterize the glyphs and store them in the atlas;
- Change the font atlas key to also take into account the smoothing
setting, not only font and font size;
- Since COSMIC Text [doesn't support controlling font
smoothing](https://github.com/pop-os/cosmic-text/issues/279), we roll
out our own threshold-based “implementation”:
- This has the downside of **looking ugly for “regular” vector fonts**
⚠️, since it doesn't properly take the hinting information into account
like a proper implementation on the rasterizer side would.
- However, **for fonts that have been specifically authored to be pixel
fonts, (a common use case in games!) this is not as big of a problem**,
since all lines are vertical/horizontal, and close to the final pixel
boundaries (as long as the font is used at a multiple of the size
originally intended by the author)
- Once COSMIC exposes this functionality, we can switch to using it
directly, and get better results;
- Use a nearest neighbor sampler for atlases with font smoothing
disabled, so that you can scale the text via transform and still get the
pixelated look;
- Add a convenience method to `Text` for setting the font smoothing;
- Add a demonstration of using the `FontSmoothing` property to the
`text2d` example.
## Testing
- Did you test these changes? If so, how?
- Yes. Via the `text2d`example, and also in my game.
- Are there any parts that need more testing?
- I'd like help from someone for testing this on devices/OSs with
fractional scaling (Android/Windows)
- How can other people (reviewers) test your changes? Is there anything
specific they need to know?
- Both via the `text2d` example and also by using it directly on your
projects.
- If relevant, what platforms did you test these changes on, and are
there any important ones you can't test?
- macOS

src="https://github.com/user-attachments/assets/b881b02c-4e43-410b-902f-6985c25140fc">
## Migration Guide
- `Text` now contains a `font_smoothing: FontSmoothing` property, make
sure to include it or add `..default()` when using the struct directly;
- `FontSizeKey` has been renamed to `FontAtlasKey`, and now also
contains the `FontSmoothing` setting;
- The following methods now take an extra `font_smoothing:
FontSmoothing` argument:
- `FontAtlas::new()`
- `FontAtlasSet::add_glyph_to_atlas()`
- `FontAtlasSet::get_glyph_atlas_info()`
- `FontAtlasSet::get_outlined_glyph_texture()`
# Objective
- Fixes#8074
- Adopts / Supersedes #8104
## Solution
Adapted from #8104 and affords the same benefits.
**Additions**
- [x] Update scrolling on relayout (height of node or contents may have
changed)
- [x] Make ScrollPosition component optional for ui nodes to avoid
checking every node on scroll
- [x] Nested scrollviews
**Omissions**
- Removed input handling for scrolling from `bevy_ui`. Users should
update `ScrollPosition` directly.
### Implementation
Adds a new `ScrollPosition` component. Updating this component on a
`Node` with an overflow axis set to `OverflowAxis::Scroll` will
reposition its children by that amount when calculating node transforms.
As before, no impact on the underlying Taffy layout.
Calculating this correctly is trickier than it was in #8104 due to
`"Update scrolling on relayout"`.
**Background**
When `ScrollPosition` is updated directly by the user, it can be
trivially handled in-engine by adding the parent's scroll position to
the final location of each child node. However, _other layout actions_
may result in a situation where `ScrollPosition` needs to be updated.
Consider a 1000 pixel tall vertically scrolling list of 100 elements,
each 100 pixels tall. Scrolled to the bottom, the
`ScrollPosition.offset_y` is 9000, just enough to display the last
element in the list. When removing an element from that list, the new
desired `ScrollPosition.offset_y` is 8900, but, critically, that is not
known until after the sizes and positions of the children of the
scrollable node are resolved.
All user scrolling code today handles this by delaying the resolution by
one frame. One notable disadvantage of this is the inability to support
`WinitSettings::desktop_app()`, since there would need to be an input
AFTER the layout change that caused the scroll position to update for
the results of the scroll position update to render visually.
I propose the alternative in this PR, which allows for same-frame
resolution of scrolling layout.
**Resolution**
_Edit: Below resolution is outdated, and replaced with the simpler usage
of taffy's `Layout::content_size`._
When recursively iterating the children of a node, each child now
returns a `Vec2` representing the location of their own bottom right
corner. Then, `[[0,0, [x,y]]` represents a bounding box containing the
scrollable area filled by that child. Scrollable parents aggregate those
areas into the bounding box of _all_ children, then consider that result
against `ScrollPosition` to ensure its validity.
In the event that resolution of the layout of the children invalidates
the `ScrollPosition` (e.g. scrolled further than there were children to
scroll to), _all_ children of that node must be recursively
repositioned. The position of each child must change as a result of the
change in scroll position.
Therefore, this implementation takes care to only spend the cost of the
"second layout pass" when a specific node actually had a
`ScrollPosition` forcibly updated by the layout of its children.
## Testing
Examples in `ui/scroll.rs`. There may be more complex node/style
interactions that were unconsidered.

## Showcase
## Alternatives
- `bevy_ui` doesn't support scrolling.
- `bevy_ui` implements scrolling with a one-frame delay on reactions to
layout changes.

## 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
rename any use of `push_children()` to the updated `add_children()`
# Objective
- Fixes https://github.com/bevyengine/bevy/pull/14991. The `cosmic-text`
shape run cache requires manual cleanup for old text that no longer
needs to be cached.
## Solution
- Add a system to trim the cache.
- Add an `average fps` indicator to the `text_debug` example.
## Testing
Tested with `cargo run --example text_debug`.
- **No shape run cache**: 82fps with ~1fps variance.
- **Shape run cache no trim**: 90-100fps with ~2-4fps variance
- **Shape run cache trim age = 1**: 90-100fps with ~2-8fps variance
- **Shape run cache trim age = 2**: 90-100fps with ~2-4fps variance
- **Shape run cache trim age = 2000**: 80-120fps with ~2-6fps variance
The shape run cache seems to increase average FPS but also increases
frame time variance (when there is dynamic text).
# Objective

incorrectly.

# Objective
- The examples use a more verbose than necessary way to initialize the
image
- The order of the camera doesn't need to be specified. At least I
didn't see a difference in my testing
## Solution
- Use `Image::new_fill()` to fill the image instead of abusing
`resize()`
- Remove the camera ordering
# Objective
- Add custom images as cursors
- Fixes#9557
## Solution
- Change cursor type to accommodate both native and image cursors
- I don't really like this solution because I couldn't use
`Handle<Image>` directly. I would need to import `bevy_assets` and that
causes a circular dependency. Alternatively we could use winit's
`CustomCursor` smart pointers, but that seems hard because the event
loop is needed to create those and is not easily accessable for users.
So now I need to copy around rgba buffers which is sad.
- I use a cache because especially on the web creating cursor images is
really slow
- Sorry to #14196 for yoinking, I just wanted to make a quick solution
for myself and thought that I should probably share it too.
Update:
- Now uses `Handle<Image>`, reads rgba data in `bevy_render` and uses
resources to send the data to `bevy_winit`, where the final cursors are
created.
## Testing
- Added example which works fine at least on Linux Wayland (winit side
has been tested with all platforms).
- I haven't tested if the url cursor works.
## Migration Guide
- `CursorIcon` is no longer a field in `Window`, but a separate
component can be inserted to a window entity. It has been changed to an
enum that can hold custom images in addition to system icons.
- `Cursor` is renamed to `CursorOptions` and `cursor` field of `Window`
is renamed to `cursor_options`
- `CursorIcon` is renamed to `SystemCursorIcon`

# Objective
This idea came up in the context of a hypothetical "text sections as
entities" where text sections are children of a text bundle.
```rust
commands
.spawn(TextBundle::default())
.with_children(|parent} {
parent.spawn(TextSection::from("Hello"));
});
```
This is a bit cumbersome (but powerful and probably the way things are
headed). [`bsn!`](https://github.com/bevyengine/bevy/discussions/14437)
will eventually make this nicer, but in the mean time, this might
improve ergonomics for the common case where there is only one
`TextSection`.
## Solution
Add a `with_child` method to the `BuildChildren` trait that spawns a
single bundle and adds it as a child to the entity.
```rust
commands
.spawn(TextBundle::default())
.with_child(TextSection::from("Hello"));
```
## Testing
I added some tests, and modified the `button` example to use the new
method.
If any potential co-authors want to improve the tests, that would be
great.
## Alternatives
- Some sort of macro. See
https://github.com/tigregalis/bevy_spans_ent/blob/main/examples/macro.rs#L20.
I don't love this, personally, and it would probably be obsoleted by
`bsn!`.
- Wait for `bsn!`
- Add `with_children_batch` that takes an `Into<Iterator>` of bundles.
```rust
with_children_batch(vec![TextSection::from("Hello")])
```
This is maybe not as useful as it sounds -- it only works with
homogeneous bundles, so no marker components or styles.
- If this doesn't seem valuable, doing nothing is cool with me.
# Objective
- Fixes#11219
## Solution
- Scaling calculations use texture dimensions instead of layout
dimensions.
## Testing
- Did you test these changes? If so, how?
All UI examples look fine.
- How can other people (reviewers) test your changes? Is there anything
specific they need to know?

```diff
let computed_slices = ComputedTextureSlices {

```
# Objective
The borders example is separate from the rounded borders example. If you
find the borders example, you may miss the rounded borders example.
## Solution
Merge the examples in a basic way, since there is enough room to show
all options at the same time.
I also considered renaming the borders and rounded borders examples so
that they would be located next to each other in repo and UI, but it
felt like having a singular example was better.
## Testing
```
cargo run --example borders
```

## Showcase
The merged example looks like this:
# Replace ab_glyph with the more capable cosmic-text
Fixes#7616.
Cosmic-text is a more mature text-rendering library that handles scripts
and ligatures better than ab_glyph, it can also handle system fonts
which can be implemented in bevy in the future
Rebase of https://github.com/bevyengine/bevy/pull/8808
## Changelog
Replaces text renderer ab_glyph with cosmic-text
The definition of the font size has changed with the migration to cosmic
text. The behavior is now consistent with other platforms (e.g. the
web), where the font size in pixels measures the height of the font (the
distance between the top of the highest ascender and the bottom of the
lowest descender). Font sizes in your app need to be rescaled to
approximately 1.2x smaller; for example, if you were using a font size
of 60.0, you should now use a font size of 50.0.
## Migration guide
- `Text2dBounds` has been replaced with `TextBounds`, and it now accepts
`Option`s to the bounds, instead of using `f32::INFINITY` to inidicate
lack of bounds
- Textsizes should be changed, dividing the current size with 1.2 will
result in the same size as before.
- `TextSettings` struct is removed
- Feature `subpixel_alignment` has been removed since cosmic-text
already does this automatically
- TextBundles and things rendering texts requires the `CosmicBuffer`
Component on them as well
## Suggested followups:
- TextPipeline: reconstruct byte indices for keeping track of eventual
cursors in text input
- TextPipeline: (future work) split text entities into section entities
- TextPipeline: (future work) text editing
- Support line height as an option. Unitless `1.2` is the default used
in browsers (1.2x font size).
- Support System Fonts and font families
- Example showing of animated text styles. Eg. throbbing hyperlinks

# Objective
Fixes#14120
`ui_texture_slice` and `ui_texture_atlas_slice` were working as
intended, so undo the changes.
## Solution
Partially revert https://github.com/bevyengine/bevy/pull/14115 for
`ui_texture_slice` and `ui_texture_atlas_slice`.
## Testing
Ran those two examples, confirmed the border color is the thing that
changes when buttons are hovered.
# Objective
- Some people have asked how to do image masking in UI. It's pretty easy
to do using a `UiMaterial` assuming you know how to write shaders.
## Solution
- Update the ui_material example to show the bevy banner slowly being
revealed like a progress bar
## Notes
I'm not entirely sure if we want this or not. For people that would be
comfortable to use this for their own games they would probably have
already figured out how to do it and for people that aren't familiar
with shaders this isn't really enough to make an actual slider/progress
bar.

# Objective
In Bevy 0.13, `BackgroundColor` simply tinted the image of any
`UiImage`. This was confusing: in every other case (e.g. Text), this
added a solid square behind the element. #11165 changed this, but
removed `BackgroundColor` from `ImageBundle` to avoid confusion, since
the semantic meaning had changed.
However, this resulted in a serious UX downgrade / inconsistency, as
this behavior was no longer part of the bundle (unlike for `TextBundle`
or `NodeBundle`), leaving users with a relatively frustrating upgrade
path.
Additionally, adding both `BackgroundColor` and `UiImage` resulted in a
bizarre effect, where the background color was seemingly ignored as it
was covered by a solid white placeholder image.
Fixes#13969.
## Solution
Per @viridia's design:
> - if you don't specify a background color, it's transparent.
> - if you don't specify an image color, it's white (because it's a
multiplier).
> - if you don't specify an image, no image is drawn.
> - if you specify both a background color and an image color, they are
independent.
> - the background color is drawn behind the image (in whatever pixels
are transparent)
As laid out by @benfrankel, this involves:
1. Changing the default `UiImage` to use a transparent texture but a
pure white tint.
2. Adding `UiImage::solid_color` to quickly set placeholder images.
3. Changing the default `BorderColor` and `BackgroundColor` to
transparent.
4. Removing the default overrides for these values in the other assorted
UI bundles.
5. Adding `BackgroundColor` back to `ImageBundle` and `ButtonBundle`.
6. Adding a 1x1 `Image::transparent`, which can be accessed from
`Assets<Image>` via the `TRANSPARENT_IMAGE_HANDLE` constant.
Huge thanks to everyone who helped out with the design in the linked
issue and [the Discord
thread](https://discord.com/channels/691052431525675048/1255209923890118697/1255209999278280844):
this was very much a joint design.
@cart helped me figure out how to set the UiImage's default texture to a
transparent 1x1 image, which is a much nicer fix.
## Testing
I've checked the examples modified by this PR, and the `ui` example as
well just to be sure.
## Migration Guide
- `BackgroundColor` no longer tints the color of images in `ImageBundle`
or `ButtonBundle`. Set `UiImage::color` to tint images instead.
- The default texture for `UiImage` is now a transparent white square.
Use `UiImage::solid_color` to quickly draw debug images.
- The default value for `BackgroundColor` and `BorderColor` is now
transparent. Set the color to white manually to return to previous
behavior.
# Objective
In a few examples, we're specifying a font or font size that is the same
as the current default value. Might as well use the default. That'll be
one less thing to worry about if we ever need to change the default font
size. (wink)
In a few others, we were using a value of `25.0` and it didn't seem like
it was different for an important reason, so I switched to the default
there too.
(There are a bunch of examples that use non-default font sizes for
various reasons. Not trying address them all here.)
# Objective
- The default font size is too small to be useful in examples or for
debug text.
- Fixes#13587
## Solution
- Updated the default font size value in `TextStyle` from 12px to 24px.
- Resorted to Text defaults in examples to use the default font size in
most of them.
## Testing
- WIP
---
## Migration Guide
- The default font size has been increased to 24px from 12px. Make sure
you set the font to the appropriate values in places you were using
`Default` text style.
## 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
- Enables support for `Display::Block`
- Enables support for `Overflow::Hidden`
- Allows for cleaner integration with text, image and other content
layout.
- Unblocks https://github.com/bevyengine/bevy/pull/8104
- Unlocks the possibility of Bevy creating a custom layout tree over
which Taffy operates.
- Enables #8808 / #10193 to remove a Mutex around the font system.
## Todo
- [x] ~Fix rendering of text/images to account for padding/border on
nodes (should size/position to content box rather than border box)~ In
order get this into a mergeable state this PR instead zeroes out
padding/border when syncing leaf node styles into Taffy to preserve the
existing behaviour. https://github.com/bevyengine/bevy/issues/6879 can
be fixed in a followup PR.
## Solution
- Update the version of Taffy
- Update code to work with the new version
Note: Taffy 0.4 has not yet been released. This PR is being created in
advance of the release to ensure that there are no blockers to upgrading
once the release occurs.
---
## Changelog
- Bevy now supports the `Display::Block` and `Overflow::Hidden` styles.
# Objective
- There are several redundant imports in the tests and examples that are
not caught by CI because additional flags need to be passed.
## Solution
- Run `cargo check --workspace --tests` and `cargo check --workspace
--examples`, then fix all warnings.
- Add `test-check` to CI, which will be run in the check-compiles job.
This should catch future warnings for tests. Examples are already
checked, but I'm not yet sure why they weren't caught.
## Discussion
- Should the `--tests` and `--examples` flags be added to CI, so this is
caught in the future?
- If so, #12818 will need to be merged first. It was also a warning
raised by checking the examples, but I chose to split off into a
separate PR.

# Objective
- Be more explicit in the name of the module for the ui debug overlay
- Avoid confusion and possible overlap with new overlays
## Solution
- Rename `debug_overlay` to `ui_debug_overlay`
# Objective
Fixes issue #12613 - the RNG used in examples is _deterministic_, but
its implementation is not _portable_ across platforms. We want to switch
to using a portable RNG that does not vary across platforms, to ensure
certain examples play out the same way every time.
## Solution
Replace all occurences of `rand::rngs::StdRng` with
`rand_chacha::ChaCha8Rng`, as recommended in issue #12613
---
## Changelog
- Add `rand_chacha` as a new dependency (controversial?)
- Replace all occurences of `rand::rngs::StdRng` with
`rand_chacha::ChaCha8Rng`
# Objective
- A new example `rounded_borders` was introduced in #12500, similar to
the `borders` example, but containing labels to describe each border,
leaving inconsistency between the examples.
## Solution
- Update the `borders` example to be consistent with `rounded_borders`.
Co-authored-by: François Mockers <mockersf@gmail.com>
# Objective
Implements border radius for UI nodes. Adopted from #8973, but excludes
shadows.
## Solution
- Add a component `BorderRadius` which contains a radius value for each
corner of the UI node.
- Use a fragment shader to generate the rounded corners using a signed
distance function.

## Changelog
- `BorderRadius`: New component that holds the border radius values.
- `NodeBundle` & `ButtonBundle`: Added a `border_radius: BorderRadius`
field.
- `extract_uinode_borders`: Stripped down, most of the work is done in
the shader now. Borders are no longer assembled from multiple rects,
instead the shader uses a signed distance function to draw the border.
- `UiVertex`: Added size, border and radius fields.
- `UiPipeline`: Added three vertex attributes to the vertex buffer
layout, to accept the UI node's size, border thickness and border
radius.
- Examples: Added rounded corners to the UI element in the `button`
example, and a `rounded_borders` example.

# Objective
- This is an adopted version of #10420
- The objective is to help debugging the Ui layout tree with helpful
outlines, that can be easily enabled/disabled
## Solution
- Like #10420, the solution is using the bevy_gizmos in outlining the
nodes
---
## Changelog
### Added
- Added debug_overlay mod to `bevy_dev_tools`
- Added bevy_ui_debug feature to `bevy_dev_tools`
## How to use
- The user must use `bevy_dev_tools` feature in TOML
- The user must use the plugin UiDebugPlugin, that can be found on
`bevy::dev_tools::debug_overlay`
- Finally, to enable the function, the user must set
`UiDebugOptions::enabled` to true
Someone can easily toggle the function with something like:
```rust
fn toggle_overlay(input: Res<ButtonInput<KeyCode>>, options: ResMut<UiDebugOptions>) {
if input.just_pressed(KeyCode::Space) {
// The toggle method will enable if disabled and disable if enabled
options.toggle();
}
}
```
Note that this feature can be disabled from dev_tools, as its in fact
behind a default feature there, being the feature bevy_ui_debug.
# Limitations
Currently, due to limitations with gizmos itself, it's not possible to
support this feature to more the one window, so this tool is limited to
the primary window only.
# Showcase
Ui example with debug_overlay enabled
And disabled

# Objective
I was wondering why the `lighting` example was still looking quite
different lately (specifically, the intensity of the green light on the
cube) and noticed that we had one more color change I didn't catch
before.
Prior to the `bevy_color` port, `PINK` was actually "deep pink" from the
css4 spec.
`palettes::css::PINK` is now correctly a lighter pink color defined by
the same spec.
```rust
// Bevy 0.13
pub const PINK: Color = Color::rgb(1.0, 0.08, 0.58);
// Bevy 0.14-dev
pub const PINK: Srgba = Srgba::new(1.0, 0.753, 0.796, 1.0);
pub const DEEP_PINK: Srgba = Srgba::new(1.0, 0.078, 0.576, 1.0);
```
## Solution
Change usages of `css::PINK` to `DEEP_PINK` to restore the examples to
their former colors.
# Objective
Fixes#12226
Prior to the `bevy_color` port, `DARK GRAY` used to mean "dark grey."
But it is now lighter than `GRAY`, matching the css4 spec.
## Solution
Change usages of `css::DARK_GRAY` to `Color::srgb(0.25, 0.25, 0.25)` to
restore the examples to their former colors.
With one exception: `display_and_visibility`. I think the new color is
an improvement.
## Note
A lot of these examples could use nicer colors. I'm not trying to revamp
everything here.
The css4 palette is truly a horror. See #12176 and #12080 for some
discussion about alternatives.
# Objective
Fixes#12225
Prior to the `bevy_color` port, `GREEN` used to mean "full green." But
it is now a much darker color matching the css1 spec.
## Solution
Change usages of `basic::GREEN` or `css::GREEN` to `LIME` to restore the
examples to their former colors.
This also removes the duplicate definition of `GREEN` from `css`. (it
was already re-exported from `basic`)
## Note
A lot of these examples could use nicer colors. I'm not trying to do
that here.
"Dark Grey" will be tackled separately and has its own tracking issue.
# Objective
Addresses one of the side-notes in #12225.
Colors in the `basic` palette are inconsistent in a few ways:
- `CYAN` was named `AQUA` in the referenced spec. (an alias was added in
a later spec)
- Colors are defined with e.g. "half green" having a `g` value of `0.5`.
But any spec would have been based on 8-bit color, so `0x80 / 0xFF` or
`128 / 255` or ~`0.502`. This precision is likely meaningful when doing
color math/rounding.
## Solution
Regenerate the colors from
https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=37563bedc8858033bd8b8380328c5230
# Objective
Follow up to #11600 and #10588https://github.com/bevyengine/bevy/issues/11944 made clear that some
people want to use slicing with texture atlases
## Changelog
* Added support for `TextureAtlas` slicing and tiling.
`SpriteSheetBundle` and `AtlasImageBundle` can now use `ImageScaleMode`
* Added new `ui_texture_atlas_slice` example using a texture sheet

# Objective
- After https://github.com/bevyengine/bevy/pull/11165, example `ui` is
not pretty as it displays the Bevy logo on a white background, with a
comment that is now wrong
## Solution
- Remove the background color
# Objective
Fixes https://github.com/bevyengine/bevy/issues/11157.
## Solution
Stop using `BackgroundColor` as a color tint for `UiImage`. Add a
`UiImage::color` field for color tint instead. Allow a UI node to
simultaneously include a solid-color background and an image, with the
image rendered on top of the background (this is already how it works
for e.g. text).
---
## Changelog
- The `BackgroundColor` component now renders a solid-color background
behind `UiImage` instead of tinting its color.
- Removed `BackgroundColor` from `ImageBundle`, `AtlasImageBundle`, and
`ButtonBundle`.
- Added `UiImage::color`.
- Expanded `RenderUiSystem` variants.
- Renamed `bevy_ui::extract_text_uinodes` to `extract_uinodes_text` for
consistency.
## Migration Guide
- `BackgroundColor` no longer tints the color of UI images. Use
`UiImage::color` for that instead.
- For solid color buttons, replace `ButtonBundle { background_color:
my_color.into(), ... }` with `ButtonBundle { image:
UiImage::default().with_color(my_color), ... }`, and update button
interaction systems to use `UiImage::color` instead of `BackgroundColor`
as well.
- `bevy_ui::RenderUiSystem::ExtractNode` has been split into
`ExtractBackgrounds`, `ExtractImages`, `ExtractBorders`, and
`ExtractText`.
- `bevy_ui::extract_uinodes` has been split into
`bevy_ui::extract_uinode_background_colors` and
`bevy_ui::extract_uinode_images`.
- `bevy_ui::extract_text_uinodes` has been renamed to
`extract_uinode_text`.
# Objective
After the `TextureAtlas` changes that landed in 0.13,
`SpriteSheetBundle` is equivalent to `TextureAtlas` + `SpriteBundle` and
`AtlasImageBundle` is equivalent to `TextureAtlas` + `ImageBundle`. As
such, the atlas bundles aren't particularly useful / necessary additions
to the API anymore.
In addition, atlas bundles are inconsistent with `ImageScaleMode` (also
introduced in 0.13) which doesn't have its own version of each image
bundle.
## Solution
Deprecate `SpriteSheetBundle` and `AtlasImageBundle` in favor of
including `TextureAtlas` as a separate component alongside
`SpriteBundle` and `ImageBundle`, respectively.
---
## Changelog
- Deprecated `SpriteSheetBundle` and `AtlasImageBundle`.
## Migration Guide
- `SpriteSheetBundle` has been deprecated. Use `TextureAtlas` alongside
a `SpriteBundle` instead.
- `AtlasImageBundle` has been deprecated. Use `TextureAtlas` alongside
an `ImageBundle` instead.
# Objective
- As part of the migration process we need to a) see the end effect of
the migration on user ergonomics b) check for serious perf regressions
c) actually migrate the code
- To accomplish this, I'm going to attempt to migrate all of the
remaining user-facing usages of `LegacyColor` in one PR, being careful
to keep a clean commit history.
- Fixes#12056.
## Solution
I've chosen to use the polymorphic `Color` type as our standard
user-facing API.
- [x] Migrate `bevy_gizmos`.
- [x] Take `impl Into<Color>` in all `bevy_gizmos` APIs
- [x] Migrate sprites
- [x] Migrate UI
- [x] Migrate `ColorMaterial`
- [x] Migrate `MaterialMesh2D`
- [x] Migrate fog
- [x] Migrate lights
- [x] Migrate StandardMaterial
- [x] Migrate wireframes
- [x] Migrate clear color
- [x] Migrate text
- [x] Migrate gltf loader
- [x] Register color types for reflection
- [x] Remove `LegacyColor`
- [x] Make sure CI passes
Incidental improvements to ease migration:
- added `Color::srgba_u8`, `Color::srgba_from_array` and friends
- added `set_alpha`, `is_fully_transparent` and `is_fully_opaque` to the
`Alpha` trait
- add and immediately deprecate (lol) `Color::rgb` and friends in favor
of more explicit and consistent `Color::srgb`
- standardized on white and black for most example text colors
- added vector field traits to `LinearRgba`: ~~`Add`, `Sub`,
`AddAssign`, `SubAssign`,~~ `Mul<f32>` and `Div<f32>`. Multiplications
and divisions do not scale alpha. `Add` and `Sub` have been cut from
this PR.
- added `LinearRgba` and `Srgba` `RED/GREEN/BLUE`
- added `LinearRgba_to_f32_array` and `LinearRgba::to_u32`
## Migration Guide
Bevy's color types have changed! Wherever you used a
`bevy::render::Color`, a `bevy::color::Color` is used instead.
These are quite similar! Both are enums storing a color in a specific
color space (or to be more precise, using a specific color model).
However, each of the different color models now has its own type.
TODO...
- `Color::rgba`, `Color::rgb`, `Color::rbga_u8`, `Color::rgb_u8`,
`Color::rgb_from_array` are now `Color::srgba`, `Color::srgb`,
`Color::srgba_u8`, `Color::srgb_u8` and `Color::srgb_from_array`.
- `Color::set_a` and `Color::a` is now `Color::set_alpha` and
`Color::alpha`. These are part of the `Alpha` trait in `bevy_color`.
- `Color::is_fully_transparent` is now part of the `Alpha` trait in
`bevy_color`
- `Color::r`, `Color::set_r`, `Color::with_r` and the equivalents for
`g`, `b` `h`, `s` and `l` have been removed due to causing silent
relatively expensive conversions. Convert your `Color` into the desired
color space, perform your operations there, and then convert it back
into a polymorphic `Color` enum.
- `Color::hex` is now `Srgba::hex`. Call `.into` or construct a
`Color::Srgba` variant manually to convert it.
- `WireframeMaterial`, `ExtractedUiNode`, `ExtractedDirectionalLight`,
`ExtractedPointLight`, `ExtractedSpotLight` and `ExtractedSprite` now
store a `LinearRgba`, rather than a polymorphic `Color`
- `Color::rgb_linear` and `Color::rgba_linear` are now
`Color::linear_rgb` and `Color::linear_rgba`
- The various CSS color constants are no longer stored directly on
`Color`. Instead, they're defined in the `Srgba` color space, and
accessed via `bevy::color::palettes::css`. Call `.into()` on them to
convert them into a `Color` for quick debugging use, and consider using
the much prettier `tailwind` palette for prototyping.
- The `LIME_GREEN` color has been renamed to `LIMEGREEN` to comply with
the standard naming.
- Vector field arithmetic operations on `Color` (add, subtract, multiply
and divide by a f32) have been removed. Instead, convert your colors
into `LinearRgba` space, and perform your operations explicitly there.
This is particularly relevant when working with emissive or HDR colors,
whose color channel values are routinely outside of the ordinary 0 to 1
range.
- `Color::as_linear_rgba_f32` has been removed. Call
`LinearRgba::to_f32_array` instead, converting if needed.
- `Color::as_linear_rgba_u32` has been removed. Call
`LinearRgba::to_u32` instead, converting if needed.
- Several other color conversion methods to transform LCH or HSL colors
into float arrays or `Vec` types have been removed. Please reimplement
these externally or open a PR to re-add them if you found them
particularly useful.
- Various methods on `Color` such as `rgb` or `hsl` to convert the color
into a specific color space have been removed. Convert into
`LinearRgba`, then to the color space of your choice.
- Various implicitly-converting color value methods on `Color` such as
`r`, `g`, `b` or `h` have been removed. Please convert it into the color
space of your choice, then check these properties.
- `Color` no longer implements `AsBindGroup`. Store a `LinearRgba`
internally instead to avoid conversion costs.

# Objective
The example showcase doesn't seem to work well with the portrait aspect
ratio used in this example, which is possibly something to be fixed
there, but there's also no reason this *needs* a custom size.
This custom window size is also sightly too tall for my particular
display which is a very common display size when accounting for the
macOS task bar and window title, so the content at the bottom is
clipped.
## Solution
- Remove the custom window size
- Swap the order of the justify / align nested loops so that the content
fits the new aspect ratio
- Make the containers responsive to window size, and make all the gaps
even

# Objective
The physical width and height (pixels) of an image is always integers,
but for `GpuImage` bevy currently stores them as `Vec2` (`f32`).
Switching to `UVec2` makes this more consistent with the [underlying
texture data](https://docs.rs/wgpu/latest/wgpu/struct.Extent3d.html).
I'm not sure if this is worth the change in the surface level API. If
not, feel free to close this PR.
## Solution
- Replace uses of `Vec2` with `UVec2` when referring to texture
dimensions.
- Use integer types for the texture atlas dimensions and sections.
[`Sprite::rect`](a81a2d1da3/crates/bevy_sprite/src/sprite.rs (L29))
remains unchanged, so manually specifying a sub-pixel region of an image
is still possible.
---
## Changelog
- `GpuImage` now stores its size as `UVec2` instead of `Vec2`.
- Texture atlases store their size and sections as `UVec2` and `URect`
respectively.
- `UiImageSize` stores its size as `UVec2`.
## Migration Guide
- Change floating point types (`Vec2`, `Rect`) to their respective
unsigned integer versions (`UVec2`, `URect`) when using `GpuImage`,
`TextureAtlasLayout`, `TextureAtlasBuilder`,
`DynamicAtlasTextureBuilder` or `FontAtlas`.
# Objective
The migration process for `bevy_color` (#12013) will be fairly involved:
there will be hundreds of affected files, and a large number of APIs.
## Solution
To allow us to proceed granularly, we're going to keep both
`bevy_color::Color` (new) and `bevy_render::Color` (old) around until
the migration is complete.
However, simply doing this directly is confusing! They're both called
`Color`, making it very hard to tell when a portion of the code has been
ported.
As discussed in #12056, by renaming the old `Color` type, we can make it
easier to gradually migrate over, one API at a time.
## Migration Guide
THIS MIGRATION GUIDE INTENTIONALLY LEFT BLANK.
This change should not be shipped to end users: delete this section in
the final migration guide!

# Objective
While doing a bunch of testing on examples, I noticed that this
particular example had lots of room for improvement. This example is
shown in example showcase, so it might as well look nice.
- The "overflow containers" have no vertical separation from each other
- The "overflow containers" are aligned awkwardly
- The instructions say you can "toggle" overflow, but it's actually
cycling through various overflow modes, with no indication of which mode
is currently active.
- The UI structure could be simplified
## Solution
- Simplify the UI structure by
- Moving the instructions into an absolutely positioned node, which we
do in most other examples with instructions
- Using a grid layout and removing some unnecessary containers
- Show the current overflow mode
- Add a gap between the overflow containers
- Other misc cleanup

# Objective
Fix https://github.com/bevyengine/bevy/issues/11577.
## Solution
Fix the examples, add a few constants to make setting light values
easier, and change the default lighting settings to be more realistic.
(Now designed for an overcast day instead of an indoor environment)
---
I did not include any example-related changes in here.
## Changelogs (not including breaking changes)
### bevy_pbr
- Added `light_consts` module (included in prelude), which contains
common lux and lumen values for lights.
- Added `AmbientLight::NONE` constant, which is an ambient light with a
brightness of 0.
- Added non-EV100 variants for `ExposureSettings`'s EV100 constants,
which allow easier construction of an `ExposureSettings` from a EV100
constant.
## Breaking changes
### bevy_pbr
The several default lighting values were changed:
- `PointLight`'s default `intensity` is now `2000.0`
- `SpotLight`'s default `intensity` is now `2000.0`
- `DirectionalLight`'s default `illuminance` is now
`light_consts::lux::OVERCAST_DAY` (`1000.`)
- `AmbientLight`'s default `brightness` is now `20.0`
> Follow up to #11600 and #10588
@mockersf expressed some [valid
concerns](https://github.com/bevyengine/bevy/pull/11600#issuecomment-1932796498)
about the current system this PR attempts to fix:
The `ComputedTextureSlices` reacts to asset change in both `bevy_sprite`
and `bevy_ui`, meaning that if the `ImageScaleMode` is inserted by
default in the bundles, we will iterate through most 2d items every time
an asset is updated.
# Solution
- `ImageScaleMode` only has two variants: `Sliced` and `Tiled`. I
removed the `Stretched` default
- `ImageScaleMode` is no longer part of any bundle, but the relevant
bundles explain that this additional component can be inserted
This way, the *absence* of `ImageScaleMode` means the image will be
stretched, and its *presence* will include the entity to the various
slicing systems
Optional components in bundles would make this more straigthfoward
# Additional work
Should I add new bundles with the `ImageScaleMode` component ?
# Objective
#11431 and #11688 implemented meshing support for Bevy's new geometric
primitives. The next step is to deprecate the shapes in
`bevy_render::mesh::shape` and to later remove them completely for 0.14.
## Solution
Deprecate the shapes and reduce code duplication by utilizing the
primitive meshing API for the old shapes where possible.
Note that some shapes have behavior that can't be exactly reproduced
with the new primitives yet:
- `Box` is more of an AABB with min/max extents
- `Plane` supports a subdivision count
- `Quad` has a `flipped` property
These types have not been changed to utilize the new primitives yet.
---
## Changelog
- Deprecated all shapes in `bevy_render::mesh::shape`
- Changed all examples to use new primitives for meshing
## Migration Guide
Bevy has previously used rendering-specific types like `UVSphere` and
`Quad` for primitive mesh shapes. These have now been deprecated to use
the geometric primitives newly introduced in version 0.13.
Some examples:
```rust
let before = meshes.add(shape::Box::new(5.0, 0.15, 5.0));
let after = meshes.add(Cuboid::new(5.0, 0.15, 5.0));
let before = meshes.add(shape::Quad::default());
let after = meshes.add(Rectangle::default());
let before = meshes.add(shape::Plane::from_size(5.0));
// The surface normal can now also be specified when using `new`
let after = meshes.add(Plane3d::default().mesh().size(5.0, 5.0));
let before = meshes.add(
Mesh::try_from(shape::Icosphere {
radius: 0.5,
subdivisions: 5,
})
.unwrap(),
);
let after = meshes.add(Sphere::new(0.5).mesh().ico(5).unwrap());
```
> Follow up to #10588
> Closes#11749 (Supersedes #11756)
Enable Texture slicing for the following UI nodes:
- `ImageBundle`
- `ButtonBundle`

src="https://github.com/bevyengine/bevy/assets/26703856/37675681-74eb-4689-ab42-024310cf3134">
I also added a collection of `fantazy-ui-borders` from
[Kenney's](www.kenney.nl) assets, with the appropriate license (CC).
If it's a problem I can use the same textures as the `sprite_slice`
example
# Work done
Added the `ImageScaleMode` component to the targetted bundles, most of
the logic is directly reused from `bevy_sprite`.
The only additional internal component is the UI specific
`ComputedSlices`, which does the same thing as its spritee equivalent
but adapted to UI code.
Again the slicing is not compatible with `TextureAtlas`, it's something
I need to tackle more deeply in the future
# Fixes
* [x] I noticed that `TextureSlicer::compute_slices` could infinitely
loop if the border was larger that the image half extents, now an error
is triggered and the texture will fallback to being stretched
* [x] I noticed that when using small textures with very small *tiling*
options we could generate hundred of thousands of slices. Now I set a
minimum size of 1 pixel per slice, which is already ridiculously small,
and a warning will be sent at runtime when slice count goes above 1000
* [x] Sprite slicing with `flip_x` or `flip_y` would give incorrect
results, correct flipping is now supported to both sprites and ui image
nodes thanks to @odecay observation
# GPU Alternative
I create a separate branch attempting to implementing 9 slicing and
tiling directly through the `ui.wgsl` fragment shader. It works but
requires sending more data to the GPU:
- slice border
- tiling factors
And more importantly, the actual quad *scale* which is hard to put in
the shader with the current code, so that would be for a later iteration
# Objective
- (Partially) Fixes#9904
- Acts on #9910
## Solution
- Deprecated the relevant methods from `Query`, cascading changes as
required across Bevy.
---
## Changelog
- Deprecated `QueryState::get_component_unchecked_mut` method
- Deprecated `Query::get_component` method
- Deprecated `Query::get_component_mut` method
- Deprecated `Query::component` method
- Deprecated `Query::component_mut` method
- Deprecated `Query::get_component_unchecked_mut` method
## Migration Guide
### `QueryState::get_component_unchecked_mut`
Use `QueryState::get_unchecked_manual` and select for the exact
component based on the structure of the exact query as required.
### `Query::(get_)component(_unchecked)(_mut)`
Use `Query::get` and select for the exact component based on the
structure of the exact query as required.
- For mutable access (`_mut`), use `Query::get_mut`
- For unchecked access (`_unchecked`), use `Query::get_unchecked`
- For panic variants (non-`get_`), add `.unwrap()`
## Notes
- `QueryComponentError` can be removed once these deprecated methods are
also removed. Due to an interaction with `thiserror`'s derive macro, it
is not marked as deprecated.
# Objective
Fixes#11503
## Solution
Use an empty set of args on the web.
## Discussion
Maybe in the future we could wrap this so that we can use query args on
the web or something, but this was the minimum changeset I could think
of to keep the functionality and make them not panic on the web.
# Objective
Implements #9216
## Solution
- Replace `DiagnosticId` by `DiagnosticPath`. It's pre-hashed using
`const-fnv1a-hash` crate, so it's possible to create path in const
contexts.
---
## Changelog
- Replaced `DiagnosticId` by `DiagnosticPath`
- Set default history length to 120 measurements (2 seconds on 60 fps).
I've noticed hardcoded constant 20 everywhere and decided to change it
to `DEFAULT_MAX_HISTORY_LENGTH` , which is set to new diagnostics by
default. To override it, use `with_max_history_length`.
## Migration Guide
```diff
- const UNIQUE_DIAG_ID: DiagnosticId = DiagnosticId::from_u128(42);
+ const UNIQUE_DIAG_PATH: DiagnosticPath = DiagnosticPath::const_new("foo/bar");
- Diagnostic::new(UNIQUE_DIAG_ID, "example", 10)
+ Diagnostic::new(UNIQUE_DIAG_PATH).with_max_history_length(10)
- diagnostics.add_measurement(UNIQUE_DIAG_ID, || 42);
+ diagnostics.add_measurement(&UNIQUE_DIAG_ID, || 42);
```
# Objective
Fixes#11376
During the development of the exposure settings PR (#11347) all examples
with lighting had to be adjusted, but three were missed or simply didn't
exist yet at the time. This PR restores the brightness in those examples
again:
render_ui_to_texture
asset_loading
hot_asset_reloading
All of them are a bit brighter now compared to before the exposure PR,
but it looks better IMO.
# Objective

> ~~Associated UI MR: #5070~~
> Adresses #1618
Unify sprite management
## Solution
- Remove the `Handle<Image>` field in `TextureAtlas` which is the main
cause for all the boilerplate
- Remove the redundant `TextureAtlasSprite` component
- Renamed `TextureAtlas` asset to `TextureAtlasLayout`
([suggestion](https://github.com/bevyengine/bevy/pull/5103#discussion_r917281844))
- Add a `TextureAtlas` component, containing the atlas layout handle and
the section index
The difference between this solution and #5072 is that instead of the
`enum` approach is that we can more easily manipulate texture sheets
without any breaking changes for classic `SpriteBundle`s (@mockersf
[comment](https://github.com/bevyengine/bevy/pull/5072#issuecomment-1165836139))
Also, this approach is more *data oriented* extracting the
`Handle<Image>` and avoiding complex texture atlas manipulations to
retrieve the texture in both applicative and engine code.
With this method, the only difference between a `SpriteBundle` and a
`SpriteSheetBundle` is an **additional** component storing the atlas
handle and the index.
~~This solution can be applied to `bevy_ui` as well (see #5070).~~
EDIT: I also applied this solution to Bevy UI
## Changelog
- (**BREAKING**) Removed `TextureAtlasSprite`
- (**BREAKING**) Renamed `TextureAtlas` to `TextureAtlasLayout`
- (**BREAKING**) `SpriteSheetBundle`:
- Uses a `Sprite` instead of a `TextureAtlasSprite` component
- Has a `texture` field containing a `Handle<Image>` like the
`SpriteBundle`
- Has a new `TextureAtlas` component instead of a
`Handle<TextureAtlasLayout>`
- (**BREAKING**) `DynamicTextureAtlasBuilder::add_texture` takes an
additional `&Handle<Image>` parameter
- (**BREAKING**) `TextureAtlasLayout::from_grid` no longer takes a
`Handle<Image>` parameter
- (**BREAKING**) `TextureAtlasBuilder::finish` now returns a
`Result<(TextureAtlasLayout, Handle<Image>), _>`
- `bevy_text`:
- `GlyphAtlasInfo` stores the texture `Handle<Image>`
- `FontAtlas` stores the texture `Handle<Image>`
- `bevy_ui`:
- (**BREAKING**) Removed `UiAtlasImage` , the atlas bundle is now
identical to the `ImageBundle` with an additional `TextureAtlas`

# Objective
Add support for presenting each UI tree on a specific window and
viewport, while making as few breaking changes as possible.
This PR is meant to resolve the following issues at once, since they're
all related.
- Fixes#5622
- Fixes#5570
- Fixes#5621
Adopted #5892 , but started over since the current codebase diverged
significantly from the original PR branch. Also, I made a decision to
propagate component to children instead of recursively iterating over
nodes in search for the root.
## Solution
Add a new optional component that can be inserted to UI root nodes and
propagate to children to specify which camera it should render onto.
This is then used to get the render target and the viewport for that UI
tree. Since this component is optional, the default behavior should be
to render onto the single camera (if only one exist) and warn of
ambiguity if multiple cameras exist. This reduces the complexity for
users with just one camera, while giving control in contexts where it
matters.
## Changelog
- Adds `TargetCamera(Entity)` component to specify which camera should a
node tree be rendered into. If only one camera exists, this component is
optional.
- Adds an example of rendering UI to a texture and using it as a
material in a 3D world.
- Fixes recalculation of physical viewport size when target scale factor
changes. This can happen when the window is moved between displays with
different DPI.
- Changes examples to demonstrate assigning UI to different viewports
and windows and make interactions in an offset viewport testable.
- Removes `UiCameraConfig`. UI visibility now can be controlled via
combination of explicit `TargetCamera` and `Visibility` on the root
nodes.

Update to `glam` 0.25, `encase` 0.7 and `hexasphere` to 10.0
## Changelog
Added the `FloatExt` trait to the `bevy_math` prelude which adds `lerp`,
`inverse_lerp` and `remap` methods to the `f32` and `f64` types.
# 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

# 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
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`.

* The `text_alignment` field of `TextMeasureInfo` has been renamed to
`justification`
## Migration Guide
* `TextAlignment` has been renamed to `JustifyText`
* `TextBundle::with_text_alignment` has been renamed to
`TextBundle::with_text_justify`
* `Text::with_alignment` has been renamed to `Text::with_justify`
* The `text_alignment` field of `TextMeasureInfo` has been renamed to
`justification`
# 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
- 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
```

`Color::from(Vec4)` is now `Color::rgba_from_array(impl Into<[f32; 4]>)`
`Vec4::from(Color)` is now `Color::rgba_to_vec4(&self)`
Before:
```rust
let color_vec4 = Vec4::new(0.5, 0.5, 0.5);
let color_from_vec4 = Color::from(color_vec4);
let color_array = [0.5, 0.5, 0.5];
let color_from_array = Color::from(color_array);
```
After:
```rust
let color_vec4 = Vec4::new(0.5, 0.5, 0.5);
let color_from_vec4 = Color::rgba_from_array(color_vec4);
let color_array = [0.5, 0.5, 0.5];
let color_from_array = Color::rgba_from_array(color_array);
```
# Objective
Fixes#10439
`Timer::percent()` and `Timer::percent_left()` return values in the

These functions should be renamed for clarity.
## Solution
- Rename `Timer::percent()` to `Timer::fraction()`
- Rename `Timer::percent_left()` to `Timer::fraction_remaining()`

# Objective
- Changes the default clear color to match the code block color on
Bevy's website.
## Solution
- Changed the clear color, updated text in examples to ensure adequate
contrast. Inconsistent usage of white text color set to use the default
color instead, which is already white.
- Additionally, updated the `3d_scene` example to make it look a bit
better, and use bevy's branding colors.
