# 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
- Currently, it is not possible to call `.pipe` on a system that takes
any input other than `()`.
- The `IntoPipeSystem` trait is currently very difficult to parse due to
its use of generics.
## Solution
Remove the `IntoPipeSystem` trait, and move the `pipe` method to
`IntoSystem`.
---
## Changelog
- System piping has been made more flexible: it is now possible to call
`.pipe` on a system that takes an input.
## Migration Guide
The `IntoPipeSystem` trait has been removed, and the `pipe` method has
been moved to the `IntoSystem` trait.
```rust
// Before:
use bevy_ecs::system::IntoPipeSystem;
schedule.add_systems(first.pipe(second));
// After:
use bevy_ecs::system::IntoSystem;
schedule.add_systems(first.pipe(second));

# Objective
`text_system` runs before the UI layout is calculated and the size of
the text node is determined, so it cannot correctly shape the text to
fit the layout, and has no way of determining if the text needs to be
wrapped.
The function `text_constraint` attempts to determine the size of the
node from the local size constraints in the `Style` component. It can't
be made to work, you have to compute the whole layout to get the correct
size. A simple example of where this fails completely is a text node set
to stretch to fill the empty space adjacent to a node with size
constraints set to `Val::Percent(50.)`. The text node will take up half
the space, even though its size constraints are `Val::Auto`
Also because the `text_system` queries for changes to the `Style`
component, when a style value is changed that doesn't affect the node's
geometry the text is recomputed unnecessarily.
Querying on changes to `Node` is not much better. The UI layout is
changed to fit the `CalculatedSize` of the text, so the size of the node
is changed and so the text and UI layout get recalculated multiple times
from a single change to a `Text`.
Also, the `MeasureFunc` doesn't work at all, it doesn't have enough
information to fit the text correctly and makes no attempt.
Fixes#7663, #6717, #5834, #1490,
## Solution
Split the `text_system` into two functions:
* `measure_text_system` which calculates the size constraints for the
text node and runs before `UiSystem::Flex`
* `text_system` which runs after `UiSystem::Flex` and generates the
actual text.
* Fix the `MeasureFunc` calculations.

## Changelog
* Removed the previous fields from `CalculatedSize`. `CalculatedSize`
now contains a boxed `Measure`.
* Added `measurement` module to `bevy_ui`.
* Added the method `create_text_measure` to `TextPipeline`.
* Added a new system `measure_text_system` that runs before
`UiSystem::Flex` that creates a `MeasureFunc` for the text.
* Rescheduled `text_system` to run after `UiSystem::Flex`.
* Added a trait `Measure`. A `Measure` is used to compute the size of a
UI node when the size of that node is based on its content.
* Added `ImageMeasure` and `TextMeasure` which implement `Measure`.
* Added a new component `UiImageSize` which is used by
`update_image_calculated_size_system` to track image size changes.
* Added a `UiImageSize` component to `ImageBundle`.
## Migration Guide
`ImageBundle` has a new component `UiImageSize` which contains the size
of the image bundle's texture and is updated automatically by
`update_image_calculated_size_system`

# Objective
The implementation of `System::run_unsafe` for `FunctionSystem` requires
that the world is the same one used to initialize the system. However,
the `System` trait has no requirements that the world actually matches,
which makes this implementation unsound.
This was previously mentioned in
https://github.com/bevyengine/bevy/pull/7605#issuecomment-1426491871
Fixes part of #7833.
## Solution
Add the safety invariant that
`System::update_archetype_component_access` must be called prior to
`System::run_unsafe`. Since
`FunctionSystem::update_archetype_component_access` properly validates
the world, this ensures that `run_unsafe` is not called with a
mismatched world.
Most exclusive systems are not required to be run on the same world that
they are initialized with, so this is not a concern for them. Systems
formed by combining an exclusive system with a regular system *do*
require the world to match, however the validation is done inside of
`System::run` when needed.
# Objective
There aren't any reflection bench tests for `Struct::clone_dynamic` or
`Reflect::get_type_info`.
## Solution
Add benches for `Struct::clone_dynamic` and `Reflect::get_type_info`.
# Objective
This PR attempts to improve query compatibility checks in scenarios
involving `Or` filters.
Currently, for the following two disjoint queries, Bevy will throw a
panic:
```
fn sys(_: Query<&mut C, Or<(With<A>, With<B>)>>, _: Query<&mut C, (Without<A>, Without<B>)>) {}
```
This PR addresses this particular scenario.
## Solution
`FilteredAccess::with` now stores a vector of `AccessFilters`
(representing a pair of `with` and `without` bitsets), where each member
represents an `Or` "variant".
Filters like `(With<A>, Or<(With<B>, Without<C>)>` are expected to be
expanded into `A * B + A * !C`.
When calculating whether queries are compatible, every `AccessFilters`
of a query is tested for incompatibility with every `AccessFilters` of
another query.

# Objective
If you want to execute a schedule on the world using arbitrarily complex
behavior, you currently need to use "hokey-pokey strats": remove the
schedule from the world, do your thing, and add it back to the world.
Not only is this cumbersome, it's potentially error-prone as one might
forget to re-insert the schedule.
## Solution
Add the `World::{try}schedule_scope{ref}` family of functions, which is
a convenient abstraction over hokey pokey strats. This method
essentially works the same way as `World::resource_scope`.
### Example
```rust
// Run the schedule five times.
world.schedule_scope(MySchedule, |world, schedule| {
for _ in 0..5 {
schedule.run(world);
}
});
```
---
## Changelog
Added the `World::schedule_scope` family of methods, which provide a way
to get mutable access to a world and one of its schedules at the same
time.

# 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.

We don't have a constructor function for `UiRect` that sets uniform
horizontal and vertical values, even though it is a common pattern.

Add a constructor function to `UiRect` called `axes`, that sets both

and sets both `top` and `bottom` to same given vertical value.

Fixes#8367
## Solution
Added a comment explaining why linear filtering is required in this
example, with formatting focused specifically on `ImagePlugin` to avoid
confusion
# Objective
Upon closer inspection, there are a few functions in the ECS that are
not being inlined, even with the highest optimizations and LTO enabled:
- Almost all
[WorldQuery::init_fetch](9fd5f20e25/results/query_get.s (L57))
calls. Affects `Query::get` calls in hot loops. In particular, the
`WorldQuery` implementation for `()` is used *everywhere* as the default
filter and is effectively a no-op.
-
[Entities::get](9fd5f20e25/results/query_get.s (L39)).
Affects `Query::get`, `World::get`, and any component insertion or
removal.
-
[Entities::set](9fd5f20e25/results/entity_remove.s (L2487)).
Affects any component insertion or removal.
-
[Tick::new](9fd5f20e25/results/entity_insert.s (L1368)).
I've only seen this in component insertion and spawning.
- ArchetypeRow::new
- BlobVec::set_len
Almost all of these have trivial or even empty implementations or have
significant opportunity to be optimized into surrounding code when
inlined with LTO enabled.
## Solution
Inline them
# Objective
The method `World::try_run_schedule` currently panics if the `Schedules`
resource does not exist, but it should just return an `Err`. Similarly,
`World::add_schedule` panics unnecessarily if the resource does not
exist.
Also, the documentation for `World::add_schedule` is completely wrong.
## Solution
When the `Schedules` resource does not exist, we now treat it the same
as if it did exist but was empty. When calling `add_schedule`, we
initialize it if it does not exist.
# Objective
Fixes#8215 and #8152. When systems panic, it causes the main thread to
panic as well, which clutters the output.
## Solution
Resolves the panic in the multi-threaded scheduler. Also adds an extra
message that tells the user the system that panicked.
Using the example from the issue, here is what the messages now look
like:
```rust
use bevy::prelude::*;
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_systems(Update, panicking_system)
.run();
}
fn panicking_system() {
panic!("oooh scary");
}
```

# Objective
Fix#8191.
Currently, a state transition will be triggered whenever the `NextState`
resource has a value, even if that "transition" is to the same state as
the previous one. This caused surprising/meaningless behavior, such as
the existence of an `OnTransition { from: A, to: A }` schedule.
## Solution
State transition schedules now only run if the new state is not equal to
the old state. Change detection works the same way, only being triggered
when the states compare not equal.
---
## Changelog
- State transition schedules are no longer run when transitioning to and
from the same state.
## Migration Guide
State transitions are now only triggered when the exited and entered
state differ. This means that if the world is currently in state `A`,
the `OnEnter(A)` schedule (or `OnExit`) will no longer be run if you
queue up a state transition to the same state `A`.
# Objective
Noticed while writing #7728 that we are using `trace!` logs in our event
functions. This has shown to have significant overhead, even trace level
logs are disabled globally, as seen in #7639.
## Solution
Use the `detailed_trace!` macro introduced in #7639. Also removed the
`event_trace` function that was only used in one location.
---
## Changelog
Changed: Event trace logs are now feature gated behind the
`detailed-trace` feature.
# Objective
Fix#8321
## Solution
The `old_viewport_size` that is used to detect whether the viewport has
changed was not being updated and thus always `None`.
# Objective
Adds a new resource to control a global volume.
Fixes#7690
---
## Solution
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`.
---
## Changelog
### 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.

# Objective
when a mesh uses zero for all bone weights, vertices end up in the
middle of the screen.
## Solution
we can address this by explicitly setting the first bone weight to 1
when the weights are given as zero. this is the approach taken by
[unity](https://forum.unity.com/threads/whats-the-problem-with-this-import-fbx-warning.133736/)
(although that also sets the bone index to zero) and
[three.js](94c1a4b86f/src/objects/SkinnedMesh.js (L98)),
and likely other engines.
## Alternatives
it does add a bit of overhead, and users can always fix this themselves,
though it's a bit awkward particularly with gltfs.

# Objective
- Fix#7263
This has nothing to do with #7024. This is for the case where the
user opted to **not** keep the same global transform on update.
## Solution
- Add a `RemovedComponent<Parent>` to `propagate_transforms`
- Add a `RemovedComponent<Parent>` and `Local<Vec<Entity>>` to
`sync_simple_transforms`
- Add test to make sure all of this works.
### Performance note
This should only incur a cost in cases where a parent is removed.
A minimal overhead (one look up in the `removed_components`
sparse set) per root entities without children which transform didn't
change. A `Vec` the size of the largest number of entities removed
with a `Parent` component in a single frame, and a binary search on
a `Vec` per root entities.
It could slow up considerably in situations where a lot of entities are
orphaned consistently during every frame, since
`sync_simple_transforms` is not parallel. But in this situation,
it is likely that the overhead of archetype updates overwhelms
everything.
---
## Changelog
- Fix the `GlobalTransform` not getting updated when `Parent` is removed
## Migration Guide
- If you called `bevy_transform::systems::sync_simple_transforms` and
`bevy_transform::systems::propagate_transforms` (which is not
re-exported by bevy) you need to account for the additional
`RemovedComponents<Parent>` parameter.

# Objective
The clippy lint `type_complexity` is known not to play well with bevy.
It frequently triggers when writing complex queries, and taking the
lint's advice of using a type alias almost always just obfuscates the
code with no benefit. Because of this, this lint is currently ignored in
CI, but unfortunately it still shows up when viewing bevy code in an
IDE.
As someone who's made a fair amount of pull requests to this repo, I
will say that this issue has been a consistent thorn in my side. Since
bevy code is filled with spurious, ignorable warnings, it can be very
difficult to spot the *real* warnings that must be fixed -- most of the
time I just ignore all warnings, only to later find out that one of them
was real after I'm done when CI runs.
## Solution
Suppress this lint in all bevy crates. This was previously attempted in
#7050, but the review process ended up making it more complicated than
it needs to be and landed on a subpar solution.
The discussion in https://github.com/rust-lang/rust-clippy/pull/10571
explores some better long-term solutions to this problem. Since there is
no timeline on when these solutions may land, we should resolve this
issue in the meantime by locally suppressing these lints.
### Unresolved issues
Currently, these lints are not suppressed in our examples, since that
would require suppressing the lint in every single source file. They are
still ignored in CI.

# 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
Text glyphs that were clipped were not sized correctly because the

Remove the scaling from the transform and multiply the size of the
glyphs by the inverse of the scale factor.
# Objective
Add helper functions to `UiImage` for creating flipped images.

* Added `with_flip_x` and `with_flip_y` methods to `UiImage` that return
the `UiImage` flipped along the respective axis.

# Objective
When a `CalculatedSize` component from a UI Node entity is removed, the
corresponding Taffy measure isn't removed which will mess up the layout
in confusing, unpredictable ways.
## Solution
Iterate through all the entities with removed `CalculatedSize`
components and remove the corresponding Taffy measures.
# 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
- RenderGraphExt was merged, but only used in limited situations
## Solution
- Fix some remaining issues with the existing api
- Use the new api in the main pass and mass writeback
- Add CORE_2D and CORE_3D constant to make render_graph code shorter
# Objective
While working on #8299, I noticed that we're using a `capacity` field,
even though `wgpu::Buffer` exposes a `size` accessor that does the same
thing.
## Solution
Remove it from all buffer wrappers. Use `wgpu::Buffer::size` instead.
Default to 0 if no buffer has been allocated yet.
# Objective
Fixes#8284. `values` is being pushed to separately from the actual
scratch buffer in `DynamicUniformBuffer::push` and
`DynamicStorageBuffer::push`. In both types, `values` is really only
used to track the number of elements being added to the buffer, yet is
causing extra allocations, size increments and excess copies.
## Solution
Remove it and its remaining uses. Replace it with accesses to `scratch`
instead.
I removed the `len` accessor, as it may be non-trivial to compute just
from `scratch`. If this is still desirable to have, we can keep a `len`
member field to track it instead of relying on `scratch`.
