# Objective
- Add Reflect and FromReflect for AssetPath
- Fixes#8458
## Solution
- Straightforward derive of `Reflect` and `FromReflect` for `AssetPath`
- Implement `Reflect` and `FromReflect` for `Cow<'static, Path>` as to
satisfy the 'static lifetime requierments of bevy_reflect.
Implementation is a direct copy of that for `Cow<'static, str>` so maybe
it begs the question that was already asked in #7429 - maybe it would be
benefitial to write a general implementation for `Reflect` for
`Cow<'static, T>`.
# Objective
- Replace the `example_showcase.sh` script
- Helper tool to prepare the example page on the website
## Solution
- Have a command to run all the examples: `cargo run -p example-showcase
-- run`
- Have a command to take screenshots of all examples: `cargo run -p
example-showcase -- run --screenshot`
- Have a command to build the markdown files for the website: `cargo run
-p example-showcase -- build-website-list --content-folder content`
- Have a command to build all the examples in wasm/WebGPU: `cargo run -p
example-showcase -- build-web-gpu-examples --content-folder webgpus`
(with `--website-hacks` to enable the hacks for the Bevy website: canvas
id, resizing and loading bar)
This is the first step to an improved example page (all examples marked
as wasm, uses the card layout, has screenshots, reuse name, category and
description from the metadata). As one of the goal is to have a page
with WebGPU examples before the official release, this is not touching
the example page for now but targeting a new one.

# Objective
`text_system` and `measure_text_system` both keep local queues to keep
track of text node entities that need recomputations/remeasurement,
which scales very badly with large numbers of text entities (O(n^2)) and
makes the code quite difficult to understand.
Also `text_system` filters for `Changed<Text>`, this isn't something
that it should do. When a text node entity fails to be processed by
`measure_text_system` because a font can't be found, the text node will
still be added to `text_system`'s local queue for recomputation. `Text`
should only ever be queued by `text_system` when a text node's geometry
is modified or a new measure is added.
## Solution
Remove the local text queues and use a component `TextFlags` to schedule
remeasurements and recomputations.
## Changelog
* Created a component `TextFlags` with fields `remeasure` and
`recompute`, which can be used to schedule a text `remeasure` or
`recomputation` respectively and added it to `TextBundle`.
* Removed the local text queues from `measure_text_system` and
`text_system` and instead use the `TextFlags` component to schedule
remeasurements and recomputations.
## Migration Guide
The component `TextFlags` has been added to `TextBundle`.
# Objective
Copy the `debug::print_tree` function from Taffy except display entity
ids instead of Taffy's node ids and indicate which ui nodes have a
measure func.
# Objective
Ensure future consistency between the two compare functions for all
types with manual `Ord` and `PartialOrd` implementations.
## Solution
Use `Self::cpm` in the implementation of `partial_cpm` for types
`Handle` and `Name`.
# Objective
there were typos in AxisSettings livezone/deadzone get/set function doc
comments.
## Solution
I changed the comments to be (hopefully) correct this time. I could be
wrong though.
# 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
Fixes#8528
## Solution
Manually implement `PartialEq`, `Eq`, `PartialOrd`, `Ord`, and `Hash`
for `bevy_ecs::event::EventId`. These new implementations do not rely on
the `Event` implementing the same traits allowing `EventId` to be used
in more cases.
# Objective
there was a typo in AxisSettings. It said "Values that are higher than
`livezone_upperbound` will be rounded up to -1.0." which I'm pretty
confident should be "1.0".
## Solution
I removed the '-'
# Objective
After fixing dynamic scene to only map specific entities, we want
map_entities to default to the less error prone behavior and have the
previous behavior renamed to "map_all_entities." As this is a breaking
change, it could not be pushed out with the bug fix.
## Solution
Simple rename and refactor.
## Changelog
### Changed
- `map_entities` now accepts a list of entities to apply to, with
`map_all_entities` retaining previous behavior of applying to all
entities in the map.
## Migration Guide
- In `bevy_ecs`, `ReflectMapEntities::map_entites` now requires an
additional `entities` parameter to specify which entities it applies to.
To keep the old behavior, use the new
`ReflectMapEntities::map_all_entities`, but consider if passing the
entities in specifically might be better for your use case to avoid
bugs.
# Objective
- I want to take screenshots of examples in CI to help with validation
of changes
## Solution
- Can override how much time is updated per frame
- Can specify on which frame to take a screenshots
- Save screenshots in CI
I reused the `TimeUpdateStrategy::ManualDuration` to be able to set the
time update strategy to a fixed duration every frame. Its previous
meaning didn't make much sense to me. This change makes it possible to
have screenshots that are exactly the same across runs.
If this gets merged, I'll add visual comparison of screenshots between
runs to ensure nothing gets broken
## Migration Guide
* `TimeUpdateStrategy::ManualDuration` meaning has changed. Instead of
setting time to `Instant::now()` plus the given duration, it sets time
to last update plus the given duration.
# Objective
- For many UI use cases (e.g. tree views, lists), it is important to be
able to imperatively sort child nodes.
- This also enables us to eventually support something like the
[`order`](https://developer.mozilla.org/en-US/docs/Web/CSS/order) CSS
property, that declaratively re-orders flex box items by a numeric
value, similar to z-index, but in space.
## Solution
We removed the ability to directly construct `Children` from `&[Entity]`
some time ago (#4197#5532) to enforce consistent hierarchies ([RFC
53](https://github.com/bevyengine/rfcs/blob/main/rfcs/53-consistent-hierarchy.md)).
If I understand it correctly, it's currently possible to re-order
children by using `Children::swap()` or
`commands.entity(id).replace_children(...)`, however these are either
too cumbersome, needlessly inefficient, and/or don't take effect
immediately.
This PR exposes the in-place sorting methods from the `slice` primitive
in `Children`, enabling imperatively sorting children in place via `&mut
Children`, while still preserving consistent hierarchies.
---
## Changelog
### Added
- The sorting methods from the `slice` primitive are now exposed by the
`Children` component, allowing imperatively sorting children in place
(Useful for UI scenarios such as lists)
# Objective
- Handle dangling entity references inside scenes
- Handle references to entities with generation > 0 inside scenes
- Fix a latent bug in `Parent`'s `MapEntities` implementation, which
would, if the parent was outside the scene, cause the scene to be loaded
into the new world with a parent reference potentially pointing to some
random entity in that new world.
- Fixes#4793 and addresses #7235
## Solution
- DynamicScenes now identify entities with a `Entity` instead of a u32,
therefore including generation
- `World` exposes a new `reserve_generations` function that despawns an
entity and advances its generation by some extra amount.
- `MapEntities` implementations have a new `get_or_reserve` function
available that will always return an `Entity`, establishing a new
mapping to a dead entity when the entity they are called with is not in
the `EntityMap`. Subsequent calls with that same `Entity` will return
the same newly created dead entity reference, preserving equality
semantics.
- As a result, after loading a scene containing references to dead
entities (or entities otherwise outside the scene), those references
will all point to different generations on a single entity id in the new
world.
---
## Changelog
### Changed
- In serialized scenes, entities are now identified by a u64 instead of
a u32.
- In serialized scenes, components with entity references now have those
references serialize as u64s instead of structs.
### Fixed
- Scenes containing components with entity references will now
deserialize and add to a world reliably.
## Migration Guide
- `MapEntities` implementations must change from a `&EntityMap`
parameter to a `&mut EntityMapper` parameter and can no longer return a
`Result`. Finally, they should switch from calling `EntityMap::get` to
calling `EntityMapper::get_or_reserve`.

# Objective
fixes#8516
* Give `CalculatedSize` a more specific and intuitive name.
* `MeasureFunc`s should only be updated when their `CalculatedSize` is
modified by the systems managing their content.
For example, suppose that you have a UI displaying an image using an
`ImageNode`. When the window is resized, the node's `MeasureFunc` will
be updated even though the dimensions of the texture contained by the
node are unchanged.
* Fix the `CalculatedSize` API so that it no longer requires the extra
boxing and the `dyn_clone` method.
## Solution
* Rename `CalculatedSize` to `ContentSize`
* Only update `MeasureFunc`s on `CalculatedSize` changes.
* Remove the `dyn_clone` method from `Measure` and move the `Measure`
from the `ContentSize` component rather than cloning it.
* Change the measure_func field of `ContentSize` to type
`Option<taffy::node::MeasureFunc>`. Add a `set` method that wraps the
given measure appropriately.
---
## Changelog
* Renamed `CalculatedSize` to `ContentSize`.
* Replaced `upsert_leaf` with a function `update_measure` that only
updates the node's `MeasureFunc`.
* `MeasureFunc`s are only updated when the `ContentSize` changes and not
when the layout changes.
* Scale factor is no longer applied to the size values passed to the
`MeasureFunc`.
* Remove the `ContentSize` scaling in `text_system`.
* The `dyn_clone` method has been removed from the `Measure` trait.
* `Measure`s are moved from the `ContentSize` component instead of
cloning them.
* Added `set` method to `ContentSize` that replaces the `new` function.
## Migration Guide
* `CalculatedSize` has been renamed to `ContentSize`.
* The `upsert_leaf` function has been removed from `UiSurface` and
replaced with `update_measure` which updates the `MeasureFunc` without
node insertion.
* The `dyn_clone` method has been removed from the `Measure` trait.
* The new function of `CalculatedSize` has been replaced with the method
`set`.
# Objective
after calling `SceneSpawner::spawn_as_child`, the scene spawner system
will always try to attach the scene instance to the parent once it is
loaded, even if the parent has been deleted, causing a panic.
## Solution
check if the parent is still alive, and don't spawn the scene instance
if not.
# 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
This is just an oversight on my part when I implemented this in
https://github.com/bevyengine/bevy/pull/7186, there isn't much reason to
print out the hash of a `Name` like it does currently:
```
Name { hash: 1608798714325729304, name: "Suzanne" } (7v0)
```
## Solution
Instead it would be better if we just printed out the string like so:
```
"Suzanne" (7v0)
```
As it conveys all of the information in a less cluttered and immediately
intuitive way which was the original purpose of `DebugName`. Which I
also think translates to `Name` as well since I mostly see it as a thin
wrapper around a string.

# Objective
> This PR is based on discussion from #6601
The Dynamic types (e.g. `DynamicStruct`, `DynamicList`, etc.) act as
both:
1. Dynamic containers which may hold any arbitrary data
2. Proxy types which may represent any other type
Currently, the only way we can represent the proxy-ness of a Dynamic is
by giving it a name.
```rust
// This is just a dynamic container
let mut data = DynamicStruct::default();
// This is a "proxy"
data.set_name(std::any::type_name::<Foo>());
```
This type name is the only way we check that the given Dynamic is a
proxy of some other type. When we need to "assert the type" of a `dyn
Reflect`, we call `Reflect::type_name` on it. However, because we're
only using a string to denote the type, we run into a few gotchas and
limitations.
For example, hashing a Dynamic proxy may work differently than the type
it proxies:
```rust
#[derive(Reflect, Hash)]
#[reflect(Hash)]
struct Foo(i32);
let concrete = Foo(123);
let dynamic = concrete.clone_dynamic();
let concrete_hash = concrete.reflect_hash();
let dynamic_hash = dynamic.reflect_hash();
// The hashes are not equal because `concrete` uses its own `Hash` impl
// while `dynamic` uses a reflection-based hashing algorithm
assert_ne!(concrete_hash, dynamic_hash);
```
Because the Dynamic proxy only knows about the name of the type, it's
unaware of any other information about it. This means it also differs on
`Reflect::reflect_partial_eq`, and may include ignored or skipped fields
in places the concrete type wouldn't.
## Solution
Rather than having Dynamics pass along just the type name of proxied
types, we can instead have them pass around the `TypeInfo`.
Now all Dynamic types contain an `Option<&'static TypeInfo>` rather than
a `String`:
```diff
pub struct DynamicTupleStruct {
- type_name: String,
+ represented_type: Option<&'static TypeInfo>,
fields: Vec<Box<dyn Reflect>>,
}
```
By changing `Reflect::get_type_info` to
`Reflect::represented_type_info`, hopefully we make this behavior a
little clearer. And to account for `None` values on these dynamic types,
`Reflect::represented_type_info` now returns `Option<&'static
TypeInfo>`.
```rust
let mut data = DynamicTupleStruct::default();
// Not proxying any specific type
assert!(dyn_tuple_struct.represented_type_info().is_none());
let type_info = <Foo as Typed>::type_info();
dyn_tuple_struct.set_represented_type(Some(type_info));
// Alternatively:
// let dyn_tuple_struct = foo.clone_dynamic();
// Now we're proxying `Foo`
assert!(dyn_tuple_struct.represented_type_info().is_some());
```
This means that we can have full access to all the static type
information for the proxied type. Future work would include
transitioning more static type information (trait impls, attributes,
etc.) over to the `TypeInfo` so it can actually be utilized by Dynamic
proxies.
### Alternatives & Rationale
> **Note**
> These alternatives were written when this PR was first made using a
`Proxy` trait. This trait has since been removed.
<details>
<summary>View</summary>
#### Alternative: The `Proxy<T>` Approach
I had considered adding something like a `Proxy<T>` type where `T` would
be the Dynamic and would contain the proxied type information.
This was nice in that it allows us to explicitly determine whether
something is a proxy or not at a type level. `Proxy<DynamicStruct>`
proxies a struct. Makes sense.
The reason I didn't go with this approach is because (1) tuples, (2)
complexity, and (3) `PartialReflect`.
The `DynamicTuple` struct allows us to represent tuples at runtime. It
also allows us to do something you normally can't with tuples: add new
fields. Because of this, adding a field immediately invalidates the
proxy (e.g. our info for `(i32, i32)` doesn't apply to `(i32, i32,
NewField)`). By going with this PR's approach, we can just remove the
type info on `DynamicTuple` when that happens. However, with the
`Proxy<T>` approach, it becomes difficult to represent this behavior—
we'd have to completely control how we access data for `T` for each `T`.
Secondly, it introduces some added complexities (aside from the manual
impls for each `T`). Does `Proxy<T>` impl `Reflect`? Likely yes, if we
want to represent it as `dyn Reflect`. What `TypeInfo` do we give it?
How would we forward reflection methods to the inner type (remember, we
don't have specialization)? How do we separate this from Dynamic types?
And finally, how do all this in a way that's both logical and intuitive
for users?
Lastly, introducing a `Proxy` trait rather than a `Proxy<T>` struct is
actually more inline with the [Unique Reflect
RFC](https://github.com/bevyengine/rfcs/pull/56). In a way, the `Proxy`
trait is really one part of the `PartialReflect` trait introduced in
that RFC (it's technically not in that RFC but it fits well with it),
where the `PartialReflect` serves as a way for proxies to work _like_
concrete types without having full access to everything a concrete
`Reflect` type can do. This would help bridge the gap between the
current state of the crate and the implementation of that RFC.
All that said, this is still a viable solution. If the community
believes this is the better path forward, then we can do that instead.
These were just my reasons for not initially going with it in this PR.
#### Alternative: The Type Registry Approach
The `Proxy` trait is great and all, but how does it solve the original
problem? Well, it doesn't— yet!
The goal would be to start moving information from the derive macro and
its attributes to the generated `TypeInfo` since these are known
statically and shouldn't change. For example, adding `ignored: bool` to
`[Un]NamedField` or a list of impls.
However, there is another way of storing this information. This is, of
course, one of the uses of the `TypeRegistry`. If we're worried about
Dynamic proxies not aligning with their concrete counterparts, we could
move more type information to the registry and require its usage.
For example, we could replace `Reflect::reflect_hash(&self)` with
`Reflect::reflect_hash(&self, registry: &TypeRegistry)`.
That's not the _worst_ thing in the world, but it is an ergonomics loss.
Additionally, other attributes may have their own requirements, further
restricting what's possible without the registry. The `Reflect::apply`
method will require the registry as well now. Why? Well because the
`map_apply` function used for the `Reflect::apply` impls on `Map` types
depends on `Map::insert_boxed`, which (at least for `DynamicMap`)
requires `Reflect::reflect_hash`. The same would apply when adding
support for reflection-based diffing, which will require
`Reflect::reflect_partial_eq`.
Again, this is a totally viable alternative. I just chose not to go with
it for the reasons above. If we want to go with it, then we can close
this PR and we can pursue this alternative instead.
#### Downsides
Just to highlight a quick potential downside (likely needs more
investigation): retrieving the `TypeInfo` requires acquiring a lock on
the `GenericTypeInfoCell` used by the `Typed` impls for generic types
(non-generic types use a `OnceBox which should be faster). I am not sure
how much of a performance hit that is and will need to run some
benchmarks to compare against.
</details>
### Open Questions
1. Should we use `Cow<'static, TypeInfo>` instead? I think that might be
easier for modding? Perhaps, in that case, we need to update
`Typed::type_info` and friends as well?
2. Are the alternatives better than the approach this PR takes? Are
there other alternatives?

## Changelog
### Changed
- `Reflect::get_type_info` has been renamed to
`Reflect::represented_type_info`
- This method now returns `Option<&'static TypeInfo>` rather than just
`&'static TypeInfo`
### Added
- Added `Reflect::is_dynamic` method to indicate when a type is dynamic
- Added a `set_represented_type` method on all dynamic types
### Removed
- Removed `TypeInfo::Dynamic` (use `Reflect::is_dynamic` instead)
- Removed `Typed` impls for all dynamic types
## Migration Guide
- The Dynamic types no longer take a string type name. Instead, they
require a static reference to `TypeInfo`:
```rust
#[derive(Reflect)]
struct MyTupleStruct(f32, f32);
let mut dyn_tuple_struct = DynamicTupleStruct::default();
dyn_tuple_struct.insert(1.23_f32);
dyn_tuple_struct.insert(3.21_f32);
// BEFORE:
let type_name = std::any::type_name::<MyTupleStruct>();
dyn_tuple_struct.set_name(type_name);
// AFTER:
let type_info = <MyTupleStruct as Typed>::type_info();
dyn_tuple_struct.set_represented_type(Some(type_info));
```
- `Reflect::get_type_info` has been renamed to
`Reflect::represented_type_info` and now also returns an
`Option<&'static TypeInfo>` (instead of just `&'static TypeInfo`):
```rust
// BEFORE:
let info: &'static TypeInfo = value.get_type_info();
// AFTER:
let info: &'static TypeInfo = value.represented_type_info().unwrap();
```
- `TypeInfo::Dynamic` and `DynamicInfo` has been removed. Use
`Reflect::is_dynamic` instead:
```rust
// BEFORE:
if matches!(value.get_type_info(), TypeInfo::Dynamic) {
// ...
}
// AFTER:
if value.is_dynamic() {
// ...
}
```

# Objective
A lot of items in `bevy_ui` could be `FromReflect` but aren't. This
prevents users and library authors from being able to convert from a
`dyn Reflect` to one of these items.
## Solution
Derive `FromReflect` where possible. Also register the
`ReflectFromReflect` type data.
# Objective
Considering that `FromReflect` is a very common trait to derive, it
would make sense to include `ReflectFromReflect` in the `bevy_reflect`
prelude so users don't need to import it separately.
## Solution
Add `ReflectFromReflect` to the prelude.
# Objective
Currently, there isn't a clean way of getting an untyped handle to an
asset during asset loading. This is useful for when an asset needs to
reference other assets, but may not know the concrete type of each
asset.
We could "hack" this together by just using some random asset:
```rust
// We don't care what `bar.baz` is, so we "pretend" it's an `Image`
let handle: Handle<Image> = load_context.get_handle("foo/bar.baz");
```
This should work since we don't actually care about the underlying type
in this case. However, we can do better.
## Solution
Add the `LoadContext::get_handle_untyped` method to get untyped handles
to assets.
# Objective
- Reduce compilation time
## Solution
- Make `spirv` and `glsl` shader format support optional. They are not
needed for Bevy shaders.
- on my mac (where shaders are compiled to `msl`), this reduces the
total build time by 2 to 5 seconds, improvement should be even better
with less cores
There is a big reduction in compile time for `naga`, and small
improvements on `wgpu` and `bevy_render`

Since #8445 fonts need to register a debug asset, otherwise the
`debug_asset_server` feature doesn't work. This adds the debug asset
registration
# 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
`Camera::logical_viewport_rect()` returns `Option<(Vec2, Vec2)>` which
is a tuple of vectors representing the `(min, max)` bounds of the
viewport rect. Since the function says it returns a rect and there is a
`Rect { min, max }` struct in `bevy_math`, using the struct will be
clearer.
## Solution
Replaced `Option<(Vec2, Vec2)>` with `Option<Rect>` for
`Camera::logical_viewport_rect()`.
---
## Changelog
- Changed `Camera::logical_viewport_rect` return type from `(Vec2,
Vec2)` to `Rect`
## Migration Guide
Before:
```
fn view_logical_camera_rect(camera_query: Query<&Camera>) {
let camera = camera_query.single();
let Some((min, max)) = camera.logical_viewport_rect() else { return };
dbg!(min, max);
}
```
After:
```
fn view_logical_camera_rect(camera_query: Query<&Camera>) {
let camera = camera_query.single();
let Some(Rect { min, max }) = camera.logical_viewport_rect() else { return };
dbg!(min, max);
}
```
# 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
Timer with zero `Duration` panics at `tick()` because of division by
zero. This PR Fixes#8463 .
## Solution
- Handle division by zero separately with `checked_div` and
`checked_rem`.
---
## Changelog
- Replace division with `checked_div`. Set `times_finished_this_tick` to
u32::MAX when duration is zero.
- Set `elapsed` to `Duration::ZERO` when timer duration is zero.
- Set `percent` to `1.0` when duration is zero.
- `times_finished_this_tick` is [not used
anywhere](https://github.com/bevyengine/bevy/search?q=times_finished_this_tick),
that's why this change will not affect other parts of the project.
- `times_finished_this_tick` is set to `0` after `reset()` and before
first `tick()` call.
# Objective
- Add `Aabb` calculation for `Sprite`, `TextureAtlasSprite` and
`Mesh2d`.
- Enable frustum culling for 2D entities since frustum culling requires
a `Aabb` component in the entity to function.
- Improve 2D performance massively when there are many sprites out of
view. (ex: `many_sprites`)
## Solution
- Derived from @Weasy666's #3944 pull request, which had no activity
since multiple months.
- Adapted the code to the latest version of Bevy.
- Added support for sprites with non-center `Anchor`s to avoid culling
prematurely when part of the sprite is still in view or not culling when
sprite is already out of view.
### Note
- Gives 15.8x performance boosts in some scenarios. (5 fps vs 79 fps
with 409600 sprites in `many_sprites`)

# 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.
This line does not appear to be an intended part of the `Panics`
section, but instead looks like it was missed when copy-pasting a
`Panics` section from above.
It confused me when I was reading the docs. At first I read it as if it
was an imperative statement saying not to use `match` statements which
seemed odd and out of place. Once I saw the code it was clearly in err.
# Objective
- Cleanup documentation string to reduce end-user confusion.
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
issue seems to be that enabling opaque also generates vertex_uvs
Fixes https://github.com/bevyengine/bevy/issues/8273
## Solution
- Use the vertex_uvs in the shader if they are present
# Objective
The first query of `measure_text_system`'s `text_queries` `ParamSet`
queries for all changed `Text` meaning that non-UI `Text` entities could
be added to its queue.
## Solution
Add a `With<Node>` query filter.
---
## Changelog
changes:
* Added a `With<Node>` query filter to first query of
`measure_text_system`'s `text_queries` `ParamSet` to ensure that only UI
node entities are added to its local queue.
* Fixed comment (text is not computed on changes to style).
