UI Scrolling (#15291)
# 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_Edit: Below resolution is outdated, and replaced with the simpler usage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.

Add a gizmo-based overlay to show UI node outlines (Adopted) (#11237)
# 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.

Camera Driven Rendering (#4745)
This adds "high level camera driven rendering" to Bevy. The goal is to give users more control over what gets rendered (and where) without needing to deal with render logic. This will make scenarios like "render to texture", "multiple windows", "split screen", "2d on 3d", "3d on 2d", "pass layering", and more significantly easier.
Here is an [example of a 2d render sandwiched between two 3d renders (each from a different perspective)](https://gist.github.com/cart/4fe56874b2e53bc5594a182fc76f4915):
Users can now spawn a camera, point it at a RenderTarget (a texture or a window), and it will "just work".
Rendering to a second window is as simple as spawning a second camera and assigning it to a specific window id:
```rust
// main camera (main window)
commands.spawn_bundle(Camera2dBundle::default());
// second camera (other window)
commands.spawn_bundle(Camera2dBundle {
camera: Camera {
target: RenderTarget::Window(window_id),
..default()
},
..default()
});
```
Rendering to a texture is as simple as pointing the camera at a texture:
```rust
commands.spawn_bundle(Camera2dBundle {
camera: Camera {
target: RenderTarget::Texture(image_handle),
..default()
},
..default()
});
```
Cameras now have a "render priority", which controls the order they are drawn in. If you want to use a camera's output texture as a texture in the main pass, just set the priority to a number lower than the main pass camera (which defaults to `0`).
```rust
// main pass camera with a default priority of 0
commands.spawn_bundle(Camera2dBundle::default());
commands.spawn_bundle(Camera2dBundle {
camera: Camera {
target: RenderTarget::Texture(image_handle.clone()),
priority: -1,
..default()
},
..default()
});
commands.spawn_bundle(SpriteBundle {
texture: image_handle,
..default()
})
```
Priority can also be used to layer to cameras on top of each other for the same RenderTarget. This is what "2d on top of 3d" looks like in the new system:
```rust
commands.spawn_bundle(Camera3dBundle::default());
commands.spawn_bundle(Camera2dBundle {
camera: Camera {
// this will render 2d entities "on top" of the default 3d camera's render
priority: 1,
..default()
},
..default()
});
```
There is no longer the concept of a global "active camera". Resources like `ActiveCamera<Camera2d>` and `ActiveCamera<Camera3d>` have been replaced with the camera-specific `Camera::is_active` field. This does put the onus on users to manage which cameras should be active.
Cameras are now assigned a single render graph as an "entry point", which is configured on each camera entity using the new `CameraRenderGraph` component. The old `PerspectiveCameraBundle` and `OrthographicCameraBundle` (generic on camera marker components like Camera2d and Camera3d) have been replaced by `Camera3dBundle` and `Camera2dBundle`, which set 3d and 2d default values for the `CameraRenderGraph` and projections.
```rust
// old 3d perspective camera
commands.spawn_bundle(PerspectiveCameraBundle::default())
// new 3d perspective camera
commands.spawn_bundle(Camera3dBundle::default())
```
```rust
// old 2d orthographic camera
commands.spawn_bundle(OrthographicCameraBundle::new_2d())
// new 2d orthographic camera
commands.spawn_bundle(Camera2dBundle::default())
```
```rust
// old 3d orthographic camera
commands.spawn_bundle(OrthographicCameraBundle::new_3d())
// new 3d orthographic camera
commands.spawn_bundle(Camera3dBundle {
projection: OrthographicProjection {
scale: 3.0,
scaling_mode: ScalingMode::FixedVertical,
..default()
}.into(),
..default()
})
```
Note that `Camera3dBundle` now uses a new `Projection` enum instead of hard coding the projection into the type. There are a number of motivators for this change: the render graph is now a part of the bundle, the way "generic bundles" work in the rust type system prevents nice `..default()` syntax, and changing projections at runtime is much easier with an enum (ex for editor scenarios). I'm open to discussing this choice, but I'm relatively certain we will all come to the same conclusion here. Camera2dBundle and Camera3dBundle are much clearer than being generic on marker components / using non-default constructors.
If you want to run a custom render graph on a camera, just set the `CameraRenderGraph` component:
```rust
commands.spawn_bundle(Camera3dBundle {
camera_render_graph: CameraRenderGraph::new(some_render_graph_name),
..default()
})
```
Just note that if the graph requires data from specific components to work (such as `Camera3d` config, which is provided in the `Camera3dBundle`), make sure the relevant components have been added.
Speaking of using components to configure graphs / passes, there are a number of new configuration options:
```rust
commands.spawn_bundle(Camera3dBundle {
camera_3d: Camera3d {
// overrides the default global clear color
clear_color: ClearColorConfig::Custom(Color::RED),
..default()
},
..default()
})
commands.spawn_bundle(Camera3dBundle {
camera_3d: Camera3d {
// disables clearing
clear_color: ClearColorConfig::None,
..default()
},
..default()
})
```
Expect to see more of the "graph configuration Components on Cameras" pattern in the future.
By popular demand, UI no longer requires a dedicated camera. `UiCameraBundle` has been removed. `Camera2dBundle` and `Camera3dBundle` now both default to rendering UI as part of their own render graphs. To disable UI rendering for a camera, disable it using the CameraUi component:
```rust
commands
.spawn_bundle(Camera3dBundle::default())
.insert(CameraUi {
is_enabled: false,
..default()
})
```
## Other Changes
* The separate clear pass has been removed. We should revisit this for things like sky rendering, but I think this PR should "keep it simple" until we're ready to properly support that (for code complexity and performance reasons). We can come up with the right design for a modular clear pass in a followup pr.
* I reorganized bevy_core_pipeline into Core2dPlugin and Core3dPlugin (and core_2d / core_3d modules). Everything is pretty much the same as before, just logically separate. I've moved relevant types (like Camera2d, Camera3d, Camera3dBundle, Camera2dBundle) into their relevant modules, which is what motivated this reorganization.
* I adapted the `scene_viewer` example (which relied on the ActiveCameras behavior) to the new system. I also refactored bits and pieces to be a bit simpler.
* All of the examples have been ported to the new camera approach. `render_to_texture` and `multiple_windows` are now _much_ simpler. I removed `two_passes` because it is less relevant with the new approach. If someone wants to add a new "layered custom pass with CameraRenderGraph" example, that might fill a similar niche. But I don't feel much pressure to add that in this pr.
* Cameras now have `target_logical_size` and `target_physical_size` fields, which makes finding the size of a camera's render target _much_ simpler. As a result, the `Assets<Image>` and `Windows` parameters were removed from `Camera::world_to_screen`, making that operation much more ergonomic.
* Render order ambiguities between cameras with the same target and the same priority now produce a warning. This accomplishes two goals:
1. Now that there is no "global" active camera, by default spawning two cameras will result in two renders (one covering the other). This would be a silent performance killer that would be hard to detect after the fact. By detecting ambiguities, we can provide a helpful warning when this occurs.
2. Render order ambiguities could result in unexpected / unpredictable render results. Resolving them makes sense.
## Follow Up Work
* Per-Camera viewports, which will make it possible to render to a smaller area inside of a RenderTarget (great for something like splitscreen)
* Camera-specific MSAA config (should use the same "overriding" pattern used for ClearColor)
* Graph Based Camera Ordering: priorities are simple, but they make complicated ordering constraints harder to express. We should consider adopting a "graph based" camera ordering model with "before" and "after" relationships to other cameras (or build it "on top" of the priority system).
* Consider allowing graphs to run subgraphs from any nest level (aka a global namespace for graphs). Right now the 2d and 3d graphs each need their own UI subgraph, which feels "fine" in the short term. But being able to share subgraphs between other subgraphs seems valuable.
* Consider splitting `bevy_core_pipeline` into `bevy_core_2d` and `bevy_core_3d` packages. Theres a shared "clear color" dependency here, which would need a new home.

Migrate UI bundles to required components (#15898)
# Objective
- Migrate UI bundles to required components, fixes #15889
## Solution
- deprecate `NodeBundle` in favor of `Node`
- deprecate `ImageBundle` in favor of `UiImage`
- deprecate `ButtonBundle` in favor of `Button`
## Testing
CI.
## Migration Guide
- Replace all uses of `NodeBundle` with `Node`. e.g.
```diff
commands
- .spawn(NodeBundle {
- style: Style {
+ .spawn((
+ Node::default(),
+ Style {
width: Val::Percent(100.),
align_items: AlignItems::Center,
justify_content: JustifyContent::Center,
..default()
},
- ..default()
- })
+ ))
```
- Replace all uses of `ButtonBundle` with `Button`. e.g.
```diff
.spawn((
- ButtonBundle {
- style: Style {
- width: Val::Px(w),
- height: Val::Px(h),
- // horizontally center child text
- justify_content: JustifyContent::Center,
- // vertically center child text
- align_items: AlignItems::Center,
- margin: UiRect::all(Val::Px(20.0)),
- ..default()
- },
- image: image.clone().into(),
+ Button,
+ Style {
+ width: Val::Px(w),
+ height: Val::Px(h),
+ // horizontally center child text
+ justify_content: JustifyContent::Center,
+ // vertically center child text
+ align_items: AlignItems::Center,
+ margin: UiRect::all(Val::Px(20.0)),
..default()
},
+ UiImage::from(image.clone()),
ImageScaleMode::Sliced(slicer.clone()),
))
```
- Replace all uses of `ImageBundle` with `UiImage`. e.g.
```diff
- commands.spawn(ImageBundle {
- image: UiImage {
+ commands.spawn((
+ UiImage {
texture: metering_mask,
..default()
},
- style: Style {
+ Style {
width: Val::Percent(100.0),
height: Val::Percent(100.0),
..default()
},
- ..default()
- });
+ ));
```

Flatten UI `Style` properties that use `Size` + remove `Size` (#8548)
# Objective
- Simplify API and make authoring styles easier
See:
https://github.com/bevyengine/bevy/issues/8540#issuecomment-1536177102
## Solution
- The `size`, `min_size`, `max_size`, and `gap` properties have been
replaced by `width`, `height`, `min_width`, `min_height`, `max_width`,
`max_height`, `row_gap`, and `column_gap` properties
---
## Changelog
- Flattened `Style` properties that have a `Size` value directly into
`Style`
## Migration Guide
- The `size`, `min_size`, `max_size`, and `gap` properties have been
replaced by the `width`, `height`, `min_width`, `min_height`,
`max_width`, `max_height`, `row_gap`, and `column_gap` properties. Use
the new properties instead.

Migrate UI bundles to required components (#15898)
# Objective
- Migrate UI bundles to required components, fixes #15889
## Solution
- deprecate `NodeBundle` in favor of `Node`
- deprecate `ImageBundle` in favor of `UiImage`
- deprecate `ButtonBundle` in favor of `Button`
## Testing
CI.
## Migration Guide
- Replace all uses of `NodeBundle` with `Node`. e.g.
```diff
commands
- .spawn(NodeBundle {
- style: Style {
+ .spawn((
+ Node::default(),
+ Style {
width: Val::Percent(100.),
align_items: AlignItems::Center,
justify_content: JustifyContent::Center,
..default()
},
- ..default()
- })
+ ))
```
- Replace all uses of `ButtonBundle` with `Button`. e.g.
```diff
.spawn((
- ButtonBundle {
- style: Style {
- width: Val::Px(w),
- height: Val::Px(h),
- // horizontally center child text
- justify_content: JustifyContent::Center,
- // vertically center child text
- align_items: AlignItems::Center,
- margin: UiRect::all(Val::Px(20.0)),
- ..default()
- },
- image: image.clone().into(),
+ Button,
+ Style {
+ width: Val::Px(w),
+ height: Val::Px(h),
+ // horizontally center child text

+ margin: UiRect::all(Val::Px(20.0)),
..default()
},
+ UiImage::from(image.clone()),
ImageScaleMode::Sliced(slicer.clone()),
))
```
- Replace all uses of `ImageBundle` with `UiImage`. e.g.
```diff
- commands.spawn(ImageBundle {
- image: UiImage {
+ commands.spawn((
+ UiImage {
texture: metering_mask,
..default()

Add a gizmo-based overlay to show UI node outlines (Adopted) (#11237)
# 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

Text rework (#15591)
**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.

Text sections are now text sections on different entities in a

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());
}

fn refresh_text(
query: Query<Entity, With<TimeText>>,
mut writer: UiTextWriter,

Text rework (#15591)
**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

Add a gizmo-based overlay to show UI node outlines (Adopted) (#11237)
# 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

And disabled

Flatten UI `Style` properties that use `Size` + remove `Size` (#8548)
# Objective
- Simplify API and make authoring styles easier
See:
https://github.com/bevyengine/bevy/issues/8540#issuecomment-1536177102
## Solution
- The `size`, `min_size`, `max_size`, and `gap` properties have been
replaced by `width`, `height`, `min_width`, `min_height`, `max_width`,
`max_height`, `row_gap`, and `column_gap` properties
---
## Changelog
- Flattened `Style` properties that have a `Size` value directly into
`Style`
## Migration Guide
- The `size`, `min_size`, `max_size`, and `gap` properties have been
replaced by the `width`, `height`, `min_width`, `min_height`,
`max_width`, `max_height`, `row_gap`, and `column_gap` properties. Use
the new properties instead.

UI Scrolling (#15291)
# 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

Migrate UI bundles to required components (#15898)
# Objective
- Migrate UI bundles to required components, fixes #15889
## Solution
- deprecate `NodeBundle` in favor of `Node`
- deprecate `ImageBundle` in favor of `UiImage`
- deprecate `ButtonBundle` in favor of `Button`
## Testing
CI.
## Migration Guide
- Replace all uses of `NodeBundle` with `Node`. e.g.
```diff
commands
- .spawn(NodeBundle {
- style: Style {
+ .spawn((
+ Node::default(),
+ Style {
width: Val::Percent(100.),
align_items: AlignItems::Center,
justify_content: JustifyContent::Center,
..default()
},
- ..default()
- })
+ ))
```
- Replace all uses of `ButtonBundle` with `Button`. e.g.
```diff
.spawn((
- ButtonBundle {
- style: Style {
- width: Val::Px(w),
- height: Val::Px(h),
- // horizontally center child text
- justify_content: JustifyContent::Center,
- // vertically center child text
- align_items: AlignItems::Center,
- margin: UiRect::all(Val::Px(20.0)),
- ..default()
- },
- image: image.clone().into(),
+ Button,
+ Style {
+ width: Val::Px(w),
+ height: Val::Px(h),
+ // horizontally center child text
+ justify_content: JustifyContent::Center,
+ // vertically center child text
+ align_items: AlignItems::Center,
+ margin: UiRect::all(Val::Px(20.0)),
..default()
},
+ UiImage::from(image.clone()),
ImageScaleMode::Sliced(slicer.clone()),
))
```
- Replace all uses of `ImageBundle` with `UiImage`. e.g.
```diff
- commands.spawn(ImageBundle {
- image: UiImage {
+ commands.spawn((
+ UiImage {
texture: metering_mask,
..default()
},
- style: Style {
+ Style {
width: Val::Percent(100.0),

Flatten UI `Style` properties that use `Size` + remove `Size` (#8548)
# Objective
- Simplify API and make authoring styles easier
See:
https://github.com/bevyengine/bevy/issues/8540#issuecomment-1536177102
## Solution
- The `size`, `min_size`, `max_size`, and `gap` properties have been
replaced by `width`, `height`, `min_width`, `min_height`, `max_width`,
`max_height`, `row_gap`, and `column_gap` properties
---
## Changelog
- Flattened `Style` properties that have a `Size` value directly into
`Style`
## Migration Guide
- The `size`, `min_size`, `max_size`, and `gap` properties have been
replaced by the `width`, `height`, `min_width`, `min_height`,
`max_width`, `max_height`, `row_gap`, and `column_gap` properties. Use
the new properties instead.

UI Scrolling (#15291)
# 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.

Text rework (#15591)
**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.

### 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.

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.

UI Scrolling (#15291)
# 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.

Migrate UI bundles to required components (#15898)
# Objective
- Migrate UI bundles to required components, fixes #15889
## Solution
- deprecate `NodeBundle` in favor of `Node`
- deprecate `ImageBundle` in favor of `UiImage`
- deprecate `ButtonBundle` in favor of `Button`
## Testing
CI.
## Migration Guide
- Replace all uses of `NodeBundle` with `Node`. e.g.
```diff
commands
- .spawn(NodeBundle {
- style: Style {
+ .spawn((
+ Node::default(),
+ Style {
width: Val::Percent(100.),
align_items: AlignItems::Center,
justify_content: JustifyContent::Center,
..default()
},
- ..default()
- })
+ ))
```
- Replace all uses of `ButtonBundle` with `Button`. e.g.
```diff
.spawn((
- ButtonBundle {
- style: Style {
- width: Val::Px(w),
- height: Val::Px(h),
- // horizontally center child text
- justify_content: JustifyContent::Center,
- // vertically center child text
- align_items: AlignItems::Center,
- margin: UiRect::all(Val::Px(20.0)),
- ..default()
- },
- image: image.clone().into(),
+ Button,
+ Style {
+ width: Val::Px(w),
+ height: Val::Px(h),
+ // horizontally center child text
+ justify_content: JustifyContent::Center,
+ // vertically center child text
+ align_items: AlignItems::Center,
+ margin: UiRect::all(Val::Px(20.0)),
..default()
},
+ UiImage::from(image.clone()),
ImageScaleMode::Sliced(slicer.clone()),
))
```
- Replace all uses of `ImageBundle` with `UiImage`. e.g.
```diff
- commands.spawn(ImageBundle {
- image: UiImage {
+ commands.spawn((
+ UiImage {
texture: metering_mask,
..default()
},
- style: Style {
+ Style {
width: Val::Percent(100.0),
height: Val::Percent(100.0),
..default()
},
- ..default()

---
## Changelog
- Flattened `Style` properties that have a `Size` value directly into
`Style`
## Migration Guide
- The `size`, `min_size`, `max_size`, and `gap` properties have been
replaced by the `width`, `height`, `min_width`, `min_height`,
`max_width`, `max_height`, `row_gap`, and `column_gap` properties. Use

Flatten UI `Style` properties that use `Size` + remove `Size` (#8548)
# Objective
- Simplify API and make authoring styles easier
See:
https://github.com/bevyengine/bevy/issues/8540#issuecomment-1536177102
## Solution
- The `size`, `min_size`, `max_size`, and `gap` properties have been
replaced by `width`, `height`, `min_width`, `min_height`, `max_width`,
`max_height`, `row_gap`, and `column_gap` properties
---
## Changelog
- Flattened `Style` properties that have a `Size` value directly into
`Style`
## Migration Guide
- The `size`, `min_size`, `max_size`, and `gap` properties have been
replaced by the `width`, `height`, `min_width`, `min_height`,
`max_width`, `max_height`, `row_gap`, and `column_gap` properties. Use
the new properties instead.

Text rework (#15591)
**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.

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.

Add a gizmo-based overlay to show UI node outlines (Adopted) (#11237)
# 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.

UI Scrolling (#15291)
# 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.
