# Objective
Since #8446, example `shader_prepass` logs the following error on my mac
m1:
```
ERROR bevy_render::render_resource::pipeline_cache: failed to process shader:
error: Entry point fragment at Fragment is invalid
= Argument 1 varying error
= Capability MULTISAMPLED_SHADING is not supported
```
The example display the 3d scene but doesn't change with the preps
selected
Maybe related to this update in naga:
cc3a8ac737
## Solution
- Disable MSAA in the example, and check if it's enabled in the shader
# Objective
- fix clippy lints early to make sure CI doesn't break when they get
promoted to stable
- have a noise-free `clippy` experience for nightly users
## Solution
- `cargo clippy --fix`
- replace `filter_map(|x| x.ok())` with `map_while(|x| x.ok())` to fix
potential infinite loop in case of IO error
# Objective
Fix the examples many_buttons and many_glyphs not working on the WebGPU
examples page. Currently they both fail with the follow error:
```
panicked at 'Only FIFO/Auto* is supported on web', ..../wgpu-0.16.0/src/backend/web.rs:1162:13
```
## Solution
Change `present_mode` from `PresentMode::Immediate` to
`PresentMode::AutoNoVsync`. AutoNoVsync seems to be common mode used by
other examples of this kind.
# 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- The `size`, `min_size`, `max_size`, and `gap` properties have been
replaced by `width`, `height`, `min_width`, `min_height`, `max_width`,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- The `size`, `min_size`, `max_size`, and `gap` properties have been
replaced by the `width`, `height`, `min_width`, `min_height`,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.

- Fix#5631
## Solution
- Wait 50ms (configurable) after the last modification event before

## Changelog
- `AssetPlugin::watch_for_changes` is now a `ChangeWatcher` instead of a
`bool`
- Fixed https://github.com/bevyengine/bevy/issues/5631
## Migration Guide
- Replace `AssetPlugin::watch_for_changes: true` with e.g.
`ChangeWatcher::with_delay(Duration::from_millis(200))`

# Objective
- Cleanup file tree
## Solution
A mysterious mod.rs lies in the scene_viewer directory. It seems
completely useless, everything ignores it and it doesn't affect
anything.
We cruelly remove it, making the world a less whimsical place. A
dystopian drive for pure and complete order compels us to eliminate all
that is useless, for clarity and to prevent the wonder and beauty of
confusion.
# Objective
`ScheduleRunnerPlugin` was still configured via a resource, meaning
users would be able to change the settings while the app is running, but
the changes wouldn't have an effect.
## Solution
Configure plugin directly
---
## Changelog
- Changed: merged `ScheduleRunnerSettings` into `ScheduleRunnerPlugin`
## Migration Guide
- instead of inserting the `ScheduleRunnerSettings` resource, configure
the `ScheduleRunnerPlugin`
# Objective
Frustum culling for 2D components has been enabled since #7885,

# Objective
- Support WebGPU
- alternative to #5027 that doesn't need any async / await
- fixes#8315
- Surprise fix#7318
## Solution
### For async renderer initialisation
- Update the plugin lifecycle:
- app builds the plugin
- calls `plugin.build`
- registers the plugin
- app starts the event loop
- event loop waits for `ready` of all registered plugins in the same
order
- returns `true` by default
- then call all `finish` then all `cleanup` in the same order as
registered
- then execute the schedule
In the case of the renderer, to avoid anything async:
- building the renderer plugin creates a detached task that will send
back the initialised renderer through a mutex in a resource
- `ready` will wait for the renderer to be present in the resource
- `finish` will take that renderer and place it in the expected
resources by other plugins
- other plugins (that expect the renderer to be available) `finish` are
called and they are able to set up their pipelines
- `cleanup` is called, only custom one is still for pipeline rendering
### For WebGPU support
- update the `build-wasm-example` script to support passing `--api
webgpu` that will build the example with WebGPU support
- feature for webgl2 was always enabled when building for wasm. it's now
in the default feature list and enabled on all platforms, so check for
this feature must also check that the target_arch is `wasm32`
---
## Migration Guide
- `Plugin::setup` has been renamed `Plugin::cleanup`
- `Plugin::finish` has been added, and plugins adding pipelines should
do it in this function instead of `Plugin::build`
```rust
// Before
impl Plugin for MyPlugin {
fn build(&self, app: &mut App) {
app.insert_resource::<MyResource>
.add_systems(Update, my_system);
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<RenderResourceNeedingDevice>()
.init_resource::<OtherRenderResource>();
}
}
// After
impl Plugin for MyPlugin {
fn build(&self, app: &mut App) {
app.insert_resource::<MyResource>
.add_systems(Update, my_system);
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<OtherRenderResource>();
}
fn finish(&self, app: &mut App) {
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<RenderResourceNeedingDevice>();
}
}
```
# Objective
- Enable taking a screenshot in wasm
- Followup on #7163
## Solution
- Create a blob from the image data, generate a url to that blob, add an
`a` element to the document linking to that url, click on that element,
then revoke the url
- This will automatically trigger a download of the screenshot file in
the browser
# Objective
- Standardize on screen instructions in examples:
- top left, bottom left when better
- white, black when better
- same margin (12px) and font size (20)
## Solution
- Started with a few examples, let's reach consensus then document and
open issues for the rest
# Objective
Provide the ability to trigger controller rumbling (force-feedback) with
a cross-platform API.
## Solution
This adds the `GamepadRumbleRequest` event to `bevy_input` and adds a
system in `bevy_gilrs` to read them and rumble controllers accordingly.
It's a relatively primitive API with a `duration` in seconds and
`GamepadRumbleIntensity` with values for the weak and strong gamepad
motors. It's is an almost 1-to-1 mapping to platform APIs. Some
platforms refer to these motors as left and right, and low frequency and
high frequency, but by convention, they're usually the same.
I used #3868 as a starting point, updated to main, removed the low-level
gilrs effect API, and moved the requests to `bevy_input` and exposed the
strong and weak intensities.
I intend this to hopefully be a non-controversial cross-platform
starting point we can build upon to eventually support more fine-grained
control (closer to the gilrs effect API)
---
## Changelog
### Added
- Gamepads can now be rumbled by sending the `GamepadRumbleRequest`
event.

# Objective
Add a bounding box gizmo
## Changes
- Added the `AabbGizmo` component that will draw the `Aabb` component on
that entity.
- Added an option to draw all bounding boxes in a scene on the
`GizmoConfig` resource.
- Added `TransformPoint` trait to generalize over the point
transformation methods on various transform types (e.g `Transform` and
`GlobalTransform`).
- Changed the `Gizmos::cuboid` method to accept an `impl TransformPoint`
instead of separate translation, rotation, and scale.
# Objective
The objective is to be able to load data from "application-specific"
(see glTF spec 3.7.2.1.) vertex attribute semantics from glTF files into
Bevy meshes.
## Solution
Rather than probe the glTF for the specific attributes supported by
Bevy, this PR changes the loader to iterate through all the attributes
and map them onto `MeshVertexAttribute`s. This mapping includes all the
previously supported attributes, plus it is now possible to add mappings
using the `add_custom_vertex_attribute()` method on `GltfPlugin`.
## Changelog
- Add support for loading custom vertex attributes from glTF files.
- Add the `custom_gltf_vertex_attribute.rs` example to illustrate
loading custom vertex attributes.
## Migration Guide
- If you were instantiating `GltfPlugin` using the unit-like struct
syntax, you must instead use `GltfPlugin::default()` as the type is no
longer unit-like.
Links in the api docs are nice. I noticed that there were several places
where structs / functions and other things were referenced in the docs,
but weren't linked. I added the links where possible / logical.

# Objective
- Enabling AlphaMode::Opaque in the shader_prepass example crashes. The

# Objective
- Have a default font
## Solution
- Add a font based on FiraMono containing only ASCII characters and use
it as the default font
- It is behind a feature `default_font` enabled by default
- I also updated examples to use it, but not UI examples to still show
how to use a custom font

Fixes https://github.com/bevyengine/bevy/issues/1207
# Objective
Right now, it's impossible to capture a screenshot of the entire window
without forking bevy. This is because
- The swapchain texture never has the COPY_SRC usage
- It can't be accessed without taking ownership of it
- Taking ownership of it breaks *a lot* of stuff
## Solution
- Introduce a dedicated api for taking a screenshot of a given bevy
window, and guarantee this screenshot will always match up with what
gets put on the screen.
---
## Changelog
- Added the `ScreenshotManager` resource with two functions,
`take_screenshot` and `save_screenshot_to_disk`
# Objective
Split the UI overflow enum so that overflow can be set for each axis
separately.
## Solution
Change `Overflow` from an enum to a struct with `x` and `y`
`OverflowAxis` fields, where `OverflowAxis` is an enum with `Clip` and
`Visible` variants. Modify `update_clipping` to calculate clipping for
each axis separately. If only one axis is clipped, the other axis is
given infinite bounds.

---
## Changelog
* Split the UI overflow implementation so overflow can be set for each
axis separately.
* Added the enum `OverflowAxis` with `Clip` and `Visible` variants.
* Changed `Overflow` to a struct with `x` and `y` fields of type
`OverflowAxis`.
* `Overflow` has new methods `visible()` and `hidden()` that replace its
previous `Clip` and `Visible` variants.
* Added `Overflow` helper methods `clip_x()` and `clip_y()` that return
a new `Overflow` value with the given axis clipped.
* Modified `update_clipping` so it calculates clipping for each axis
separately. If a node is only clipped on a single axis, the other axis
is given `-f32::INFINITY` to `f32::INFINITY` clipping bounds.
## Migration Guide
The `Style` property `Overflow` is now a struct with `x` and `y` fields,
that allow for per-axis overflow control.
Use these helper functions to replace the variants of `Overflow`:
* Replace `Overflow::Visible` with `Overflow::visible()`
* Replace `Overflow::Hidden` with `Overflow::clip()`
# Objective
Followup to #7779 which tweaks the actual text measurement algorithm to
be more robust.

(note extra space taken up in header in before example)
## Solution
- Text layout of horizontal text (currently the only kind of text we
support) is now based solely on the layout constraints in the horizontal
axis. It ignores constraints in the vertical axis and computes vertical
size based on wrapping subject to the horizontal axis constraints.
- I've also added a paragraph to the `grid` example for testing / demo
purposes.
# Objective
An easy way to create 2D grid layouts
## Solution
Enable the `grid` feature in Taffy and add new style types for defining
grids.
## Notes
- ~I'm having a bit of trouble getting `#[derive(Reflect)]` to work
properly. Help with that would be appreciated (EDIT: got it to compile
by ignoring the problematic fields, but this presumably can't be
merged).~ This is now fixed
- ~The alignment types now have a `Normal` variant because I couldn't
get reflect to work with `Option`.~ I've decided to stick with the
flattened variant, as it saves a level of wrapping when authoring
styles. But I've renamed the variants from `Normal` to `Default`.
- ~This currently exposes a simplified API on top of grid. In particular
the following is not currently supported:~
- ~Negative grid indices~ Now supported.
- ~Custom `end` values for grid placement (you can only use `start` and
`span`)~ Now supported
- ~`minmax()` track sizing functions~ minmax is now support through a
`GridTrack::minmax()` constructor
- ~`repeat()`~ repeat is now implemented as `RepeatedGridTrack`
- ~Documentation still needs to be improved.~ An initial pass over the
documentation has been completed.

# Objective
Bevy provides an easy way to build the `examples/README.md` page, but
it's difficult to discover.
By adding instructions in `CONTRIBUTING.md`, it's easier to find that
it's possible to avoid this error-prone manual process.
Precisely: #8405 took me about 1 additional hour searching what command
to use to generate automatically the file. (I could have manually edited
the README, but that's beyond the point…)
# Objective
- The old post processing example doesn't use the actual post processing
features of bevy. It also has some issues with resizing. It's also
causing some confusion for people because accessing the prepass textures
from it is not easy.
- There's already a render to texture example
- At this point, it's mostly obsolete since the post_process_pass
example is more complete and shows the recommended way to do post
processing in bevy. It's a bit more complicated, but it's well
documented and I'm working on simplifying it even more
## Solution
- Remove the old post_processing example
- Rename post_process_pass to post_processing
## Reviewer Notes
The diff is really noisy because of the rename, but I didn't change any
code in the example.

Added a new resource to control global volume, this is then multiplied
with an audio sources volume to get the output volume, individual audio
sources can opt out of this my enabling the `absolute_volume` field in
`PlaybackSettings`.

### Added
- `GlobalVolume` a resource to control global volume (in prelude).
- `global_volume` field to `AudioPlugin` or setting the initial value of
`GlobalVolume`.
- `Volume` enum that can be `Relative` or `Absolute`.
- `VolumeLevel` struct for defining a volume level.

Fixes issue mentioned in PR #8285.
_Note: By mistake, this is currently dependent on #8285_
# Objective
Ensure consistency in the spelling of the documentation.
Exceptions:
`crates/bevy_mikktspace/src/generated.rs` - Has not been changed from
licence to license as it is part of a licensing agreement.
Maybe for further consistency,
https://github.com/bevyengine/bevy-website should also be given a look.
## Solution
### Changed the spelling of the current words (UK/CN/AU -> US) :
cancelled -> canceled (Breaking API changes in #8285)
behaviour -> behavior (Breaking API changes in #8285)
neighbour -> neighbor
grey -> gray
recognise -> recognize
centre -> center
metres -> meters
colour -> color
### ~~Update [`engine_style_guide.md`]~~ Moved to #8324

# Objective
Make the coordinate systems of screen-space items (cursor position, UI,
viewports, etc.) consistent.
## Solution
Remove the weird double inversion of the cursor position's Y origin.
Once in bevy_winit to the bottom and then again in bevy_ui back to the
top.
This leaves the origin at the top left like it is in every other popular
app framework.
Update the `world_to_viewport`, `viewport_to_world`, and
`viewport_to_world_2d` methods to flip the Y origin (as they should
since the viewport coordinates were always relative to the top left).
## Migration Guide
`Window::cursor_position` now returns the position of the cursor
relative to the top left instead of the bottom left.
This now matches other screen-space coordinates like
`RelativeCursorPosition`, UI, and viewports.
The `world_to_viewport`, `viewport_to_world`, and `viewport_to_world_2d`
methods on `Camera` now return/take the viewport position relative to
the top left instead of the bottom left.
If you were using `world_to_viewport` to position a UI node the returned
`y` value should now be passed into the `top` field on `Style` instead
of the `bottom` field.
Note that this might shift the position of the UI node as it is now
anchored at the top.
If you were passing `Window::cursor_position` to `viewport_to_world` or
`viewport_to_world_2d` no change is necessary.
# Objective
In the
[`Text`](3442a13d2c/crates/bevy_text/src/text.rs (L18))
struct the field is named: `linebreak_behaviour`, the British spelling
of _behavior_.
**Update**, also found:
- `FileDragAndDrop::HoveredFileCancelled`
- `TouchPhase::Cancelled`
- `Touches.just_cancelled`
The majority of all spelling is in the US but when you have a lot of
contributors across the world, sometimes
spelling differences can pop up in APIs such as in this case.
For consistency, I think it would be worth a while to ensure that the
API is persistent.
Some examples:
`from_reflect.rs` has `DefaultBehavior`
TextStyle has `color` and uses the `Color` struct.
In `bevy_input/src/Touch.rs` `TouchPhase::Cancelled` and _canceled_ are
used interchangeably in the documentation
I've found that there is also the same type of discrepancies in the
documentation, though this is a low priority but is worth checking.
**Update**: I've now checked the documentation (See #8291)
## Solution
I've only renamed the inconsistencies that have breaking changes and
documentation pertaining to them. The rest of the documentation will be
changed via #8291.
Do note that the winit API is written with UK spelling, thus this may be
a cause for confusion:
`winit::event::TouchPhase::Cancelled => TouchPhase::Canceled`
`winit::event::WindowEvent::HoveredFileCancelled` -> Related to
`FileDragAndDrop::HoveredFileCanceled`
But I'm hoping to maybe outline other spelling inconsistencies in the
API, and maybe an addition to the contribution guide.
---
## Changelog
- `Text` field `linebreak_behaviour` has been renamed to
`linebreak_behavior`.
- Event `FileDragAndDrop::HoveredFileCancelled` has been renamed to
`HoveredFileCanceled`
- Function `Touches.just_cancelled` has been renamed to
`Touches.just_canceled`
- Event `TouchPhase::Cancelled` has been renamed to
`TouchPhase::Canceled`
## Migration Guide
Update where `linebreak_behaviour` is used to `linebreak_behavior`
Updated the event `FileDragAndDrop::HoveredFileCancelled` where used to
`HoveredFileCanceled`
Update `Touches.just_cancelled` where used as `Touches.just_canceled`
The event `TouchPhase::Cancelled` is now called `TouchPhase::Canceled`
# Objective
- Adding a node to the render_graph can be quite verbose and error prone
because there's a lot of moving parts to it.
## Solution
- Encapsulate this in a simple utility method
- Mostly intended for optional nodes that have specific ordering
- Requires that the `Node` impl `FromWorld`, but every internal node is
built using a new function taking a `&mut World` so it was essentially
already `FromWorld`
- Use it for the bloom, fxaa and taa, nodes.
- The main nodes don't use it because they rely more on the order of
many nodes being added
---
## Changelog
- Impl `FromWorld` for `BloomNode`, `FxaaNode` and `TaaNode`
- Added `RenderGraph::add_node_edges()`
- Added `RenderGraph::sub_graph()`
- Added `RenderGraph::sub_graph_mut()`
- Added `RenderGraphApp`, `RenderGraphApp::add_render_graph_node`,
`RenderGraphApp::add_render_graph_edges`,
`RenderGraphApp::add_render_graph_edge`
## Notes
~~This was taken out of https://github.com/bevyengine/bevy/pull/7995
because it works on it's own. Once the linked PR is done, the new
`add_node()` will be simplified a bit since the input/output params
won't be necessary.~~
This feature will be useful in most of the upcoming render nodes so it's
impact will be more relevant at that point.
Partially fixes#7985
## Future work
* Add a way to automatically label nodes or at least make it part of the
trait. This would remove one more field from the functions added in this
PR
* Use it in the main pass 2d/3d

# Objective
TAA, FXAA, and some other post processing effects can cause the image to
become blurry. Sharpening helps to counteract that.
## Solution
~~This is a port of AMD's Contrast Adaptive Sharpening (I ported it from
the
[SweetFX](https://github.com/CeeJayDK/SweetFX/blob/master/Shaders/CAS.fx)
version, which is still MIT licensed). CAS is a good sharpening
algorithm that is better at avoiding the full screen oversharpening
artifacts that simpler algorithms tend to create.~~
This is a port of AMD's Robust Contrast Adaptive Sharpening (RCAS) which
they developed for FSR 1 ([and continue to use in FSR
2](149cf26e12/src/ffx-fsr2-api/shaders/ffx_fsr1.h (L599))).
RCAS is a good sharpening algorithm that is better at avoiding the full
screen oversharpening artifacts that simpler algorithms tend to create.
---
## Future Work
- Consider porting this to a compute shader for potentially better
performance. (In my testing it is currently ridiculously cheap (0.01ms
in Bistro at 1440p where I'm GPU bound), so this wasn't a priority,
especially since it would increase complexity due to still needing the
non-compute version for webgl2 support).
---
## Changelog
- Added Contrast Adaptive Sharpening.

# Objective
- Closes https://github.com/bevyengine/bevy/issues/8008
## Solution
- Add a skybox plugin that renders a fullscreen triangle, and then
modifies the vertices in a vertex shader to enforce that it renders as a
skybox background.
- Skybox is run at the end of MainOpaquePass3dNode.
- In the future, it would be nice to get something like bevy_atmosphere
built-in, and have a default skybox+environment map light.
---
## Changelog
- Added `Skybox`.
- `EnvironmentMapLight` now renders in the correct orientation.
## Migration Guide
- Flip `EnvironmentMapLight` maps if needed to match how they previously
rendered (which was backwards).
