# Objective
- Add a test case for #14300Fixes#14300
## Solution
`SceneEntityMapper` relies on operations on `Entities` that require
flushing in advance, such as `alloc` and `free`. Previously, it wasn't
calling `world.flush_entities()` itself and relied on its caller having
flushed beforehand. This wasn't an issue before observers and hooks were
released, since entity reservation was happening at expected times. Now
that hooks and observers are a thing, they can introduce a need to
flush.
We have a few options:
* Flush after each observer/hook run
* Flush between each paired observer/hook and operation that requires a
flush
* Flush before operations requiring it
The first option for this case seemed trickier to reason about than I
wanted, since it involved the `BundleInserter` and its
`UnsafeWorldCell`, and the second is generally harder to track down. The
third seemed the most straightforward and conventional, since we can see
a flush occurring at the start of a number of `World` methods.
Therefore, we're letting `SceneEntityMapper` be in charge of upholding
its own invariants and calling `flush_entities` when it's created.
## Testing
Added a new test case modeled after #14300
# Objective
- Fixes#15373
- Fixes
https://github.com/bevyengine/bevy/pull/14920#issuecomment-2370428013
## Solution
- Make `IntoSystem::pipe` and `IntoSystem::map` return two new
(possibly-ZST) types that implement `IntoSystem` and whose `into_system`
method return the systems that were previously being returned by
`IntoSystem::pipe` and `IntoSystem::map`
- Don't eagerly call `IntoSystem::into_system` on the argument given to
`RunSystemCachedWith::new` to avoid losing its ZST-ness
## Testing
- Added a regression test for each issue
## Migration Guide
- `IntoSystem::pipe` and `IntoSystem::map` now return `IntoPipeSystem`
and `IntoAdapterSystem` instead of `PipeSystem` and `AdapterSystem`.
Most notably these types don't implement `System` but rather only
`IntoSystem`.
# Objective
Fixes#15401
## Solution
Changes the scroll inversion hotkey in the example from Shift to
Control.
Shift is idiomatic for this. Since we cannot use Shift per #15401, I
picked another modifier arbitrarily. A production app would handle this
in a platform specific way until the platform behaviors are unified
upstream, but no point here.
## Testing
I don't have a mac readily available for testing, if someone wouldn't
mind testing. I would also appreciate confirmation that trackpad is
working nicely.
The logic in PR #14808 broke `bevy_asset_loader`, because calling
`AssetServer::load_untyped()` initiates a load of an asset of type
`LoadedUntypedAsset`, which doesn't match any asset loaders and
therefore fails. I reverted the lines that were causing the problem. The
resulting code seems to work, but I'm not sure if this was the correct
fix.
# Objective
Fixes#14467
Observers and component lifecycle hooks are allowed to perform
operations that subsequently require `Entities` to be flushed, such as
reserving a new entity. If this occurs during an `on_remove` hook or an
`OnRemove` event trigger during an `EntityWorldMut::despawn`, a panic
will occur.
## Solution
Call `world.flush_entities()` after running `on_remove` hooks/observers
during `despawn`
## Testing
Added a new test that fails before the fix and succeeds afterward.
# Objective
#15349 added an `impl_reflect!` for `glam::EulerRot`. This was done by
copying and pasting the enum definition from `glam` into `bevy_reflect`
so that the macro could interpret the variants.
However, as mentioned in the description for that PR, this would need to
be updated for `glam` 0.29, as it had not been updated yet.
#15249 came and updated `glam` to 0.29, but did not change these impls.
This is understandable as failing to do so doesn't cause any compile
errors.
This PR updates the definition and aims to make this silent breakage a
little less silent.
## Solution
Firstly, I updated the definition for `EulerRot` to match the one from
`glam`.
Secondly, I added the `assert_type_match` crate, which I created
specifically to solve this problem. By using this crate, we'll get a
compile time error if `glam` ever decides to change `EulerRot` again.
In the future we can consider using it for other types with this
problem, including in other crates (I'm pretty sure `bevy_window` and/or
`bevy_winit` also copy+paste some types). I made sure to use as few
dependencies as possible so everything should already be in-tree (it's
just `quote`, `proc-macro2`, and `syn` with default features).
## Testing
No tests added. CI should pass.
---
## Migration Guide
The reflection implementation for `EulerRot` has been updated to align
with `glam` 0.29. Please update any reflection-based usages accordingly.
# Objective
I'm building a game where i generate a set of meshes where the transform
is identity, and in each mesh the vertices are offset to where the model
is. When adding visibility ranges to the models i noticed that they only
switched when the distance to the origin changed over the threshold and
all at the same time.
## Solution
I believe that each mesh gets a Aabb generated for use with visibility
testing. So we can use that aabb to calculate a more representative
distance to the mesh.
The code to transform the aabb is taken from the visibility sysyem.
## Testing
I tested the changes locally in my project.
Would you like me to write an example or a test somewhere?
Is there any other code that uses the visibility range, that i should
also update?
# Objective
Fix "system skipped" warnings when validation fails on systems that
wouldn't run because of run conditions.
## Solution
> I think the error is from a system defined as:
>
> ```rust
> no_gpu_preprocessing::batch_and_prepare_sorted_render_phase::<SPI,
GFBD>
> .run_if(resource_exists::<BatchedInstanceBuffer<GFBD::BufferData>>),
> ```
>
> So the `run_if` was preventing the panics. Maybe we need to skip
validation if `!system_conditions_met`, or at least silence the warning
in that case.

Validation of system is skipped if the system was already skipped by run

# Objective
Adopted from #13563.
The goal is to implement the Bevy Remote Protocol over HTTP/JSON,
allowing the ECS to be interacted with remotely.
## Solution
At a high level, there are really two separate things that have been
undertaken here:
1. First, `RemotePlugin` has been created, which has the effect of
embedding a [JSON-RPC](https://www.jsonrpc.org/specification) endpoint
into a Bevy application.
2. Second, the [Bevy Remote Protocol
verbs](https://gist.github.com/coreh/1baf6f255d7e86e4be29874d00137d1d#file-bevy-remote-protocol-md)
(excluding `POLL`) have been implemented as remote methods for that
JSON-RPC endpoint under a Bevy-exclusive namespace (e.g. `bevy/get`,
`bevy/list`, etc.).
To avoid some repetition, here is the crate-level documentation, which
explains the request/response structure, built-in-methods, and custom
method configuration:
<details>
<summary>Click to view crate-level docs</summary>
```rust
//! An implementation of the Bevy Remote Protocol over HTTP and JSON, to allow
//! for remote control of a Bevy app.
//!
//! Adding the [`RemotePlugin`] to your [`App`] causes Bevy to accept
//! connections over HTTP (by default, on port 15702) while your app is running.
//! These *remote clients* can inspect and alter the state of the
//! entity-component system. Clients are expected to `POST` JSON requests to the
//! root URL; see the `client` example for a trivial example of use.
//!
//! The Bevy Remote Protocol is based on the JSON-RPC 2.0 protocol.
//!
//! ## Request objects
//!
//! A typical client request might look like this:
//!
//! ```json
//! {
//! "method": "bevy/get",
//! "id": 0,
//! "params": {
//! "entity": 4294967298,
//! "components": [
//! "bevy_transform::components::transform::Transform"
//! ]
//! }
//! }
//! ```
//!
//! The `id` and `method` fields are required. The `param` field may be omitted
//! for certain methods:
//!
//! * `id` is arbitrary JSON data. The server completely ignores its contents,
//! and the client may use it for any purpose. It will be copied via
//! serialization and deserialization (so object property order, etc. can't be
//! relied upon to be identical) and sent back to the client as part of the
//! response.
//!
//! * `method` is a string that specifies one of the possible [`BrpRequest`]
//! variants: `bevy/query`, `bevy/get`, `bevy/insert`, etc. It's case-sensitive.
//!
//! * `params` is parameter data specific to the request.
//!
//! For more information, see the documentation for [`BrpRequest`].
//! [`BrpRequest`] is serialized to JSON via `serde`, so [the `serde`
//! documentation] may be useful to clarify the correspondence between the Rust
//! structure and the JSON format.
//!
//! ## Response objects
//!
//! A response from the server to the client might look like this:
//!
//! ```json
//! {
//! "jsonrpc": "2.0",
//! "id": 0,
//! "result": {
//! "bevy_transform::components::transform::Transform": {
//! "rotation": { "x": 0.0, "y": 0.0, "z": 0.0, "w": 1.0 },
//! "scale": { "x": 1.0, "y": 1.0, "z": 1.0 },
//! "translation": { "x": 0.0, "y": 0.5, "z": 0.0 }
//! }
//! }
//! }
//! ```
//!
//! The `id` field will always be present. The `result` field will be present if the
//! request was successful. Otherwise, an `error` field will replace it.
//!
//! * `id` is the arbitrary JSON data that was sent as part of the request. It
//! will be identical to the `id` data sent during the request, modulo
//! serialization and deserialization. If there's an error reading the `id` field,
//! it will be `null`.
//!
//! * `result` will be present if the request succeeded and will contain the response
//! specific to the request.
//!
//! * `error` will be present if the request failed and will contain an error object
//! with more information about the cause of failure.
//!
//! ## Error objects
//!
//! An error object might look like this:
//!
//! ```json
//! {
//! "code": -32602,
//! "message": "Missing \"entity\" field"
//! }
//! ```
//!
//! The `code` and `message` fields will always be present. There may also be a `data` field.
//!
//! * `code` is an integer representing the kind of an error that happened. Error codes documented
//! in the [`error_codes`] module.
//!
//! * `message` is a short, one-sentence human-readable description of the error.
//!
//! * `data` is an optional field of arbitrary type containing additional information about the error.
//!
//! ## Built-in methods
//!
//! The Bevy Remote Protocol includes a number of built-in methods for accessing and modifying data
//! in the ECS. Each of these methods uses the `bevy/` prefix, which is a namespace reserved for
//! BRP built-in methods.
//!
//! ### bevy/get
//!
//! Retrieve the values of one or more components from an entity.
//!
//! `params`:
//! - `entity`: The ID of the entity whose components will be fetched.
//! - `components`: An array of fully-qualified type names of components to fetch.
//!
//! `result`: A map associating each type name to its value on the requested entity.
//!
//! ### bevy/query
//!
//! Perform a query over components in the ECS, returning all matching entities and their associated
//! component values.
//!
//! All of the arrays that comprise this request are optional, and when they are not provided, they
//! will be treated as if they were empty.
//!
//! `params`:
//! `params`:
//! - `data`:
//! - `components` (optional): An array of fully-qualified type names of components to fetch.
//! - `option` (optional): An array of fully-qualified type names of components to fetch optionally.
//! - `has` (optional): An array of fully-qualified type names of components whose presence will be
//! reported as boolean values.
//! - `filter` (optional):
//! - `with` (optional): An array of fully-qualified type names of components that must be present
//! on entities in order for them to be included in results.
//! - `without` (optional): An array of fully-qualified type names of components that must *not* be
//! present on entities in order for them to be included in results.
//!
//! `result`: An array, each of which is an object containing:
//! - `entity`: The ID of a query-matching entity.
//! - `components`: A map associating each type name from `components`/`option` to its value on the matching
//! entity if the component is present.
//! - `has`: A map associating each type name from `has` to a boolean value indicating whether or not the
//! entity has that component. If `has` was empty or omitted, this key will be omitted in the response.
//!
//! ### bevy/spawn
//!
//! Create a new entity with the provided components and return the resulting entity ID.
//!
//! `params`:
//! - `components`: A map associating each component's fully-qualified type name with its value.
//!
//! `result`:
//! - `entity`: The ID of the newly spawned entity.
//!
//! ### bevy/destroy
//!
//! Despawn the entity with the given ID.
//!
//! `params`:
//! - `entity`: The ID of the entity to be despawned.
//!
//! `result`: null.
//!
//! ### bevy/remove
//!
//! Delete one or more components from an entity.
//!
//! `params`:
//! - `entity`: The ID of the entity whose components should be removed.
//! - `components`: An array of fully-qualified type names of components to be removed.
//!
//! `result`: null.
//!
//! ### bevy/insert
//!
//! Insert one or more components into an entity.
//!
//! `params`:
//! - `entity`: The ID of the entity to insert components into.
//! - `components`: A map associating each component's fully-qualified type name with its value.
//!
//! `result`: null.
//!
//! ### bevy/reparent
//!
//! Assign a new parent to one or more entities.
//!
//! `params`:
//! - `entities`: An array of entity IDs of entities that will be made children of the `parent`.
//! - `parent` (optional): The entity ID of the parent to which the child entities will be assigned.
//! If excluded, the given entities will be removed from their parents.
//!
//! `result`: null.
//!
//! ### bevy/list
//!
//! List all registered components or all components present on an entity.
//!
//! When `params` is not provided, this lists all registered components. If `params` is provided,
//! this lists only those components present on the provided entity.
//!
//! `params` (optional):
//! - `entity`: The ID of the entity whose components will be listed.
//!
//! `result`: An array of fully-qualified type names of components.
//!
//! ## Custom methods
//!
//! In addition to the provided methods, the Bevy Remote Protocol can be extended to include custom
//! methods. This is primarily done during the initialization of [`RemotePlugin`], although the
//! methods may also be extended at runtime using the [`RemoteMethods`] resource.
//!
//! ### Example
//! ```ignore
//! fn main() {
//! App::new()
//! .add_plugins(DefaultPlugins)
//! .add_plugins(
//! // `default` adds all of the built-in methods, while `with_method` extends them
//! RemotePlugin::default()
//! .with_method("super_user/cool_method".to_owned(), path::to::my:🆒:handler)
//! // ... more methods can be added by chaining `with_method`
//! )
//! .add_systems(
//! // ... standard application setup
//! )
//! .run();
//! }
//! ```
//!
//! The handler is expected to be a system-convertible function which takes optional JSON parameters
//! as input and returns a [`BrpResult`]. This means that it should have a type signature which looks
//! something like this:
//! ```
//! # use serde_json::Value;
//! # use bevy_ecs::prelude::{In, World};
//! # use bevy_remote::BrpResult;
//! fn handler(In(params): In<Option<Value>>, world: &mut World) -> BrpResult {
//! todo!()
//! }
//! ```
//!
//! Arbitrary system parameters can be used in conjunction with the optional `Value` input. The
//! handler system will always run with exclusive `World` access.
//!
//! [the `serde` documentation]: https://serde.rs/
```
</details>
### Message lifecycle
At a high level, the lifecycle of client-server interactions is
something like this:
1. The client sends one or more `BrpRequest`s. The deserialized version
of that is just the Rust representation of a JSON-RPC request, and it
looks like this:
```rust
pub struct BrpRequest {
/// The action to be performed. Parsing is deferred for the sake of error reporting.
pub method: Option<Value>,
/// Arbitrary data that will be returned verbatim to the client as part of
/// the response.
pub id: Option<Value>,
/// The parameters, specific to each method.
///
/// These are passed as the first argument to the method handler.
/// Sometimes params can be omitted.
pub params: Option<Value>,
}
```
2. These requests are accumulated in a mailbox resource (small lie but
close enough).
3. Each update, the mailbox is drained by a system
`process_remote_requests`, where each request is processed according to
its `method`, which has an associated handler. Each handler is a Bevy
system that runs with exclusive world access and returns a result; e.g.:
```rust
pub fn process_remote_get_request(In(params): In<Option<Value>>, world: &World) -> BrpResult { // ... }
```
4. The result (or an error) is reported back to the client.
## Testing
This can be tested by using the `server` and `client` examples. The
`client` example is not particularly exhaustive at the moment (it only
creates barebones `bevy/query` requests) but is still informative. Other
queries can be made using `curl` with the `server` example running.
For example, to make a `bevy/list` request and list all registered
components:
```bash
curl -X POST -d '{ "jsonrpc": "2.0", "id": 1, "method": "bevy/list" }' 127.0.0.1:15702 | jq .
```
---
## Future direction
There were a couple comments on BRP versioning while this was in draft.
I agree that BRP versioning is a good idea, but I think that it requires
some consensus on a couple fronts:
- First of all, what does the version actually mean? Is it a version for
the protocol itself or for the `bevy/*` methods implemented using it?
Both?
- Where does the version actually live? The most natural place is just
where we have `"jsonrpc"` right now (at least if it's versioning the
protocol itself), but this means we're not actually conforming to
JSON-RPC any more (so, for example, any client library used to construct
JSON-RPC requests would stop working). I'm not really against that, but
it's at least a real decision.
- What do we actually do when we encounter mismatched versions? Adding
handling for this would be actual scope creep instead of just a little
add-on in my opinion.
Another thing that would be nice is making the internal structure of the
implementation less JSON-specific. Right now, for example, component
values that will appear in server responses are quite eagerly converted
to JSON `Value`s, which prevents disentangling the handler logic from
the communication medium, but it can probably be done in principle and I
imagine it would enable more code reuse (e.g. for custom method
handlers) in addition to making the internals more readily usable for
other formats.

# Objective
Currently, the term "value" in the context of reflection is a bit
overloaded.
For one, it can be used synonymously with "data" or "variable". An
example sentence would be "this function takes a reflected value".
However, it is also used to refer to reflected types which are
`ReflectKind::Value`. These types are usually either primitives, opaque
types, or types that don't fall into any other `ReflectKind` (or perhaps
could, but don't due to some limitation/difficulty). An example sentence
would be "this function takes a reflected value type".
This makes it difficult to write good documentation or other learning
material without causing some amount of confusion to readers. Ideally,
we'd be able to move away from the `ReflectKind::Value` usage and come
up with a better term.
## Solution
This PR replaces the terminology of "value" with "opaque" across
`bevy_reflect`. This includes in documentation, type names, variant
names, and macros.
The term "opaque" was chosen because that's essentially how the type is
treated within the reflection API. In other words, its internal
structure is hidden. All we can do is work with the type itself.
### Primitives
While primitives are not technically opaque types, I think it's still
clearer to refer to them as "opaque" rather than keep the confusing
"value" terminology.
We could consider adding another concept for primitives (e.g.
`ReflectKind::Primitive`), but I'm not sure that provides a lot of
benefit right now. In most circumstances, they'll be treated just like
an opaque type. They would also likely use the same macro (or two copies
of the same macro but with different names).
## Testing
You can test locally by running:
```
cargo test --package bevy_reflect --all-features
```
---
## Migration Guide
The reflection concept of "value type" has been replaced with a clearer
"opaque type". The following renames have been made to account for this:
- `ReflectKind::Value` → `ReflectKind::Opaque`
- `ReflectRef::Value` → `ReflectRef::Opaque`
- `ReflectMut::Value` → `ReflectMut::Opaque`
- `ReflectOwned::Value` → `ReflectOwned::Opaque`
- `TypeInfo::Value` → `TypeInfo::Opaque`
- `ValueInfo` → `OpaqueInfo`
- `impl_reflect_value!` → `impl_reflect_opaque!`
- `impl_from_reflect_value!` → `impl_from_reflect_opaque!`
Additionally, declaring your own opaque types no longer uses
`#[reflect_value]`. This attribute has been replaced by
`#[reflect(opaque)]`:
```rust
// BEFORE
#[derive(Reflect)]
#[reflect_value(Default)]
struct MyOpaqueType(u32);
// AFTER
#[derive(Reflect)]
#[reflect(opaque)]
#[reflect(Default)]
struct MyOpaqueType(u32);
```
Note that the order in which `#[reflect(opaque)]` appears does not
matter.

# Objective
- Fixes#14924
- Closes#9584
## Solution
- We introduce a new trait, `SystemInput`, that serves as a type
function from the `'static` form of the input, to its lifetime'd
version, similarly to `SystemParam` or `WorldQuery`.
- System functions now take the lifetime'd wrapped version,
`SystemInput::Param<'_>`, which prevents the issue presented in #14924
(i.e. `InRef<T>`).
- Functions for running systems now take the lifetime'd unwrapped
version, `SystemInput::Inner<'_>` (i.e. `&T`).
- Due to the above change, system piping had to be re-implemented as a
standalone type, rather than `CombinatorSystem` as it was previously.
- Removes the `Trigger<'static, E, B>` transmute in observer runner
code.
## Testing
- All current tests pass.
- Added additional tests and doc-tests.
---
## Showcase
```rust
let mut world = World::new();
let mut value = 2;
// Currently possible:
fn square(In(input): In<usize>) -> usize {
input * input
}
value = world.run_system_once_with(value, square);
// Now possible:
fn square_mut(InMut(input): InMut<usize>) {
*input *= *input;
}
world.run_system_once_with(&mut value, square_mut);
// Or:
fn square_ref(InRef(input): InRef<usize>) -> usize {
*input * *input
}
value = world.run_system_once_with(&value, square_ref);
```
## Migration Guide
- All current explicit usages of the following types must be changed in
the way specified:
- `SystemId<I, O>` to `SystemId<In<I>, O>`
- `System<In = T>` to `System<In = In<T>>`
- `IntoSystem<I, O, M>` to `IntoSystem<In<I>, O, M>`
- `Condition<M, T>` to `Condition<M, In<T>>`
- `In<Trigger<E, B>>` is no longer a valid input parameter type. Use
`Trigger<E, B>` directly, instead.

# Objective
Fixes#15351
## Solution
- Created new external crate and ported over the code
## Testing
- CI
## Migration guide
Replace references to `bevy_utils::ShortName` with
`disqualified::ShortName`.
# Objective
- Fix https://github.com/bevyengine/bevy/issues/15366. `cosmic-text`
buffers refuse to function if the `Metrics` font size is zero.
## Solution
- Trick `cosmic-text` into clearing its internal buffer when the largest
font size of segments is zero by sending it no spans and a tiny
`Metrics::font_size` and `Metrics::line_height`.
## Testing
- [x] Fixes @brandon-reinhart 's bug.
# Objective
- Fixes#10720
- Adds the ability to control font smoothing of rendered text
## Solution
- Introduce the `FontSmoothing` enum, with two possible variants
(`FontSmoothing::None` and `FontSmoothing::AntiAliased`):
- This is based on `-webkit-font-smoothing`, in line with our practice
of adopting CSS-like properties/names for UI;
- I could have gone instead for the [`font-smooth`
property](https://developer.mozilla.org/en-US/docs/Web/CSS/font-smooth)
that's also supported by browsers, but didn't since it's also
non-standard, has an uglier name, and doesn't allow controlling the type
of antialias applied.
- Having an enum instead of e.g. a boolean, leaves the path open for
adding `FontSmoothing::SubpixelAntiAliased` in the future, without a
breaking change;
- Add all the necessary plumbing to get the `FontSmoothing` information
to where we rasterize the glyphs and store them in the atlas;
- Change the font atlas key to also take into account the smoothing
setting, not only font and font size;
- Since COSMIC Text [doesn't support controlling font
smoothing](https://github.com/pop-os/cosmic-text/issues/279), we roll
out our own threshold-based “implementation”:
- This has the downside of **looking ugly for “regular” vector fonts**
⚠️, since it doesn't properly take the hinting information into account
like a proper implementation on the rasterizer side would.
- However, **for fonts that have been specifically authored to be pixel
fonts, (a common use case in games!) this is not as big of a problem**,
since all lines are vertical/horizontal, and close to the final pixel
boundaries (as long as the font is used at a multiple of the size
originally intended by the author)
- Once COSMIC exposes this functionality, we can switch to using it
directly, and get better results;
- Use a nearest neighbor sampler for atlases with font smoothing
disabled, so that you can scale the text via transform and still get the
pixelated look;
- Add a convenience method to `Text` for setting the font smoothing;
- Add a demonstration of using the `FontSmoothing` property to the
`text2d` example.
## Testing
- Did you test these changes? If so, how?
- Yes. Via the `text2d`example, and also in my game.
- Are there any parts that need more testing?
- I'd like help from someone for testing this on devices/OSs with
fractional scaling (Android/Windows)
- How can other people (reviewers) test your changes? Is there anything
specific they need to know?
- Both via the `text2d` example and also by using it directly on your
projects.
- If relevant, what platforms did you test these changes on, and are
there any important ones you can't test?
- macOS

## Showcase
```rust
commands.spawn(Text2dBundle {

.with_font_smoothing(FontSmoothing::None),

## Migration Guide
- `Text` now contains a `font_smoothing: FontSmoothing` property, make
sure to include it or add `..default()` when using the struct directly;
- `FontSizeKey` has been renamed to `FontAtlasKey`, and now also
contains the `FontSmoothing` setting;
- The following methods now take an extra `font_smoothing:
FontSmoothing` argument:
- `FontAtlas::new()`
- `FontAtlasSet::add_glyph_to_atlas()`
- `FontAtlasSet::get_glyph_atlas_info()`
- `FontAtlasSet::get_outlined_glyph_texture()`
# Objective
In order to derive `Reflect`, all of a struct's fields must implement
`FromReflect`. [As part of looking into some of the work mentioned
here](https://github.com/bevyengine/bevy/issues/13713#issuecomment-2364786694),
I noticed that `TextureFormat` doesn't implement `Reflect`, and decided
to split that into a separate PR.
## Solution
I decided that `TextureFormat` should be a `reflect_value` since,
although one variant has fields, most users will treat this as an opaque
value set explicitly. It also substantially reduces the complexity of
the implementation.
For now, this implementation isn't actually used by any crates, so, I
decided to not preemptively enable the feature on anything. But it's
technically an option, now, and more `wgpu` types can be added in the
future.
## Testing
Everything compiles okay, and I can't really see how this could be done
incorrectly given the above constraints.
# Objective
Currently, Bevy implements reflection for `glam::EulerRot` using:
```rs
impl_reflect_value!(::glam::EulerRot(Debug, Default, Deserialize, Serialize));
```
Treating it as an opaque type. However, it's useful to expose the
EulerRot enum variants directly, which I make use of from a drop down
selection box in `bevy_egui`. This PR changes this to use
`impl_reflect!`.
**Importantly**, Bevy currently uses glam 0.28.0, in which `EulerRot`
has just 6 variants. In glam 0.29.0, this is exanded to 24 variants, see
bb2ab05613.
When Bevy updates to 0.29.0, this reflect impl must also be updated to
include the new variants.
## Solution
Replaces the `impl_reflect_value!` with `impl_reflect!` and a
handwritten version of `EulerRot` with the same variants.
## Testing
Added a `tests` module to `glam.rs` to ensure that de/serialization
works. However, my main concern is making sure that the number of enum
variants matches glam's, which I'm not sure how to do using `Enum`.
# Objective
There's currently no way to iterate through all the type data in a
`TypeRegistration`. While these are all type-erased, it can still be
useful to see what types (by `TypeId`) are registered for a given type.
Additionally, it might be good to have ways of dynamically working with
`TypeRegistration`.
## Solution
Added a way to iterate through all type data on a given
`TypeRegistration`. This PR also adds methods for working with type data
dynamically as well as methods for conveniently checking if a given type
data exists on the registration.
I also took this opportunity to reorganize the methods on
`TypeRegistration` as it has always bothered me haha (i.e. the
constructor not being at the top, etc.).
## Testing
You can test locally by running:
```
cargo test --package bevy_reflect
```
---
## Showcase
The type-erased type data on a `TypeRegistration` can now be iterated!
```rust
#[derive(Reflect)]
struct Foo;
#[derive(Clone)]
struct DataA(i32);
#[derive(Clone)]
struct DataB(i32);
let mut registration = TypeRegistration::of::<Foo>();
registration.insert(DataA(123));
registration.insert(DataB(456));
let mut iter = registration.iter();
let (id, data) = iter.next().unwrap();
assert_eq!(id, TypeId::of::<DataA>());
assert_eq!(data.downcast_ref::<DataA>().unwrap().0, 123);
let (id, data) = iter.next().unwrap();
assert_eq!(id, TypeId::of::<DataB>());
assert_eq!(data.downcast_ref::<DataB>().unwrap().0, 456);
assert!(iter.next().is_none());
```
# 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.
Currently, Bevy restricts animation clips to animating
`Transform::translation`, `Transform::rotation`, `Transform::scale`, or
`MorphWeights`, which correspond to the properties that glTF can
animate. This is insufficient for many use cases such as animating UI,
as the UI layout systems expect to have exclusive control over UI
elements' `Transform`s and therefore the `Style` properties must be
animated instead.
This commit fixes this, allowing for `AnimationClip`s to animate
arbitrary properties. The `Keyframes` structure has been turned into a
low-level trait that can be implemented to achieve arbitrary animation
behavior. Along with `Keyframes`, this patch adds a higher-level trait,
`AnimatableProperty`, that simplifies the task of animating single
interpolable properties. Built-in `Keyframes` implementations exist for
translation, rotation, scale, and morph weights. For the most part, you
can migrate by simply changing your code from
`Keyframes::Translation(...)` to `TranslationKeyframes(...)`, and
likewise for rotation, scale, and morph weights.
An example `AnimatableProperty` implementation for the font size of a
text section follows:
#[derive(Reflect)]
struct FontSizeProperty;
impl AnimatableProperty for FontSizeProperty {
type Component = Text;
type Property = f32;
fn get_mut(component: &mut Self::Component) -> Option<&mut
Self::Property> {
Some(&mut component.sections.get_mut(0)?.style.font_size)
}
}
In order to keep this patch relatively small, this patch doesn't include
an implementation of `AnimatableProperty` on top of the reflection
system. That can be a follow-up.
This patch builds on top of the new `EntityMutExcept<>` type in order to
widen the `AnimationTarget` query to include write access to all
components. Because `EntityMutExcept<>` has some performance overhead
over an explicit query, we continue to explicitly query `Transform` in
order to avoid regressing the performance of skeletal animation, such as
the `many_foxes` benchmark. I've measured the performance of that
benchmark and have found no significant regressions.
A new example, `animated_ui`, has been added. This example shows how to
use Bevy's built-in animation infrastructure to animate font size and
color, which wasn't possible before this patch.
## Showcase
https://github.com/user-attachments/assets/1fa73492-a9ce-405a-a8f2-4aacd7f6dc97
## Migration Guide
* Animation keyframes are now an extensible trait, not an enum. Replace
`Keyframes::Translation(...)`, `Keyframes::Scale(...)`,
`Keyframes::Rotation(...)`, and `Keyframes::Weights(...)` with
`Box::new(TranslationKeyframes(...))`, `Box::new(ScaleKeyframes(...))`,
`Box::new(RotationKeyframes(...))`, and
`Box::new(MorphWeightsKeyframes(...))` respectively.
# Objective
Functions created into `DynamicFunction[Mut]` do not currently validate
the number of arguments they are given before calling the function.
I originally did this because I felt users would want to validate this
themselves in the function rather than have it be done
behind-the-scenes. I'm now realizing, however, that we could remove this
boilerplate and if users wanted to check again then they would still be
free to do so (it'd be more of a sanity check at that point).
## Solution
Automatically validate the number of arguments passed to
`DynamicFunction::call` and `DynamicFunctionMut::call[_once]`.
This is a pretty trivial change since we just need to compare the length
of the `ArgList` to the length of the `[ArgInfo]` in the function's
`FunctionInfo`.
I also ran the benchmarks just in case and saw no regression by doing
this.
## Testing
You can test locally by running:
```
cargo test --package bevy_reflect --all-features
```
# Objective
The goal of this PR is to introduce `SystemParam` validation in order to
reduce runtime panics.
Fixes#15265
## Solution
`SystemParam` now has a new method `validate_param(...) -> bool`, which
takes immutable variants of `get_param` arguments. The returned value
indicates whether the parameter can be acquired from the world. If
parameters cannot be acquired for a system, it won't be executed,
similarly to run conditions. This reduces panics when using params like
`Res`, `ResMut`, etc. as well as allows for new, ergonomic params like
#15264 or #15302.
Param validation happens at the level of executors. All validation
happens directly before executing a system, in case of normal systems
they are skipped, in case of conditions they return false.
Warning about system skipping is primitive and subject to change in
subsequent PRs.
## Testing
Two executor tests check that all executors:
- skip systems which have invalid parameters:
- piped systems get skipped together,
- dependent systems still run correctly,
- skip systems with invalid run conditions:
- system conditions have invalid parameters,
- system set conditions have invalid parameters.
# Objective
#13320 added convenience methods for casting a `TypeInfo` into its
respective variant:
```rust
let info: &TypeInfo = <Vec<i32> as Typed>::type_info();
// We know `info` contains a `ListInfo`, so we can simply cast it:
let list_info: &ListInfo = info.as_list().unwrap();
```
This is especially helpful when you have already verified a type is a
certain kind via `ReflectRef`, `ReflectMut`, `ReflectOwned`, or
`ReflectKind`.
As mentioned in that PR, though, it would be useful to add similar
convenience methods to those types as well.
## Solution
Added convenience casting methods to `ReflectRef`, `ReflectMut`, and
`ReflectOwned`.
With these methods, I was able to reduce our nesting in certain places
throughout the crate.
Additionally, I took this opportunity to move these types (and
`ReflectKind`) to their own module to help clean up the `reflect`
module.
## Testing
You can test locally by running:
```
cargo test --package bevy_reflect --all-features
```
---
## Showcase
Convenience methods for casting `ReflectRef`, `ReflectMut`, and
`ReflectOwned` into their respective variants has been added! This
allows you to write cleaner code if you already know the kind of your
reflected data:
```rust
// BEFORE
let ReflectRef::List(list) = list.reflect_ref() else {
panic!("expected list");
};
// AFTER
let list = list.reflect_ref().as_list().unwrap();
```

# Objective
Working with `World` is painful due to lifetime issues and a lack of
ergonomics, so you may want to delegate to the system API. Your current
options are:
- `world.run_system_once`, which initializes the system each time it's
called (performance cost) and doesn't support `Local`. The docs
recommend users not use this method outside of diagnostic use cases like
unit tests.
- `world.run_system`, which requires you to register the system and
store the `SystemId` somewhere (made easier by implementing `FromWorld`
for a newtyped `Local`, unless you're in e.g. a custom `Command` impl).
These options work, but you're choosing between a performance cost and
an ergonomic challenge.
## Solution
Provide a cached `run_system` API that accepts an `S: IntoSystem` and
checks for a `CachedSystemId<S::System>(SystemId)` resource. If it
doesn't exist, it will register the system and save its `SystemId` in
that resource.
In other words, it hides the "save the `SystemId` in a `Local` or
`Resource`" pattern as an implementation detail.

# Objective
While #13152 added function reflection, it didn't really make functions
reflectable. Instead, it made it so that they can be called with
reflected arguments and return reflected data. But functions themselves
cannot be reflected.
In other words, we can't go from `DynamicFunction` to `dyn
PartialReflect`.
## Solution
Allow `DynamicFunction` to actually be reflected.
This PR adds the `Function` reflection subtrait (and corresponding
`ReflectRef`, `ReflectKind`, etc.). With this new trait, we're able to
implement `PartialReflect` on `DynamicFunction`.
### Implementors
`Function` is currently only implemented for `DynamicFunction<'static>`.
This is because we can't implement it generically over all
functions—even those that implement `IntoFunction`.
What about `DynamicFunctionMut`? Well, this PR does **not** implement
`Function` for `DynamicFunctionMut`.
The reasons for this are a little complicated, but it boils down to
mutability. `DynamicFunctionMut` requires `&mut self` to be invoked
since it wraps a `FnMut`. However, we can't really model this well with
`Function`. And if we make `DynamicFunctionMut` wrap its internal
`FnMut` in a `Mutex` to allow for `&self` invocations, then we run into
either concurrency issues or recursion issues (or, in the worst case,
both).
So for the time-being, we won't implement `Function` for
`DynamicFunctionMut`. It will be better to evaluate it on its own. And
we may even consider the possibility of removing it altogether if it
adds too much complexity to the crate.
### Dynamic vs Concrete
One of the issues with `DynamicFunction` is the fact that it's both a
dynamic representation (like `DynamicStruct` or `DynamicList`) and the
only way to represent a function.
Because of this, it's in a weird middle ground where we can't easily
implement full-on `Reflect`. That would require `Typed`, but what static
`TypeInfo` could it provide? Just that it's a `DynamicFunction`? None of
the other dynamic types implement `Typed`.
However, by not implementing `Reflect`, we lose the ability to downcast
back to our `DynamicStruct`. Our only option is to call
`Function::clone_dynamic`, which clones the data rather than by simply
downcasting. This works in favor of the `PartialReflect::try_apply`
implementation since it would have to clone anyways, but is definitely
not ideal. This is also the reason I had to add `Debug` as a supertrait
on `Function`.
For now, this PR chooses not to implement `Reflect` for
`DynamicFunction`. We may want to explore this in a followup PR (or even
this one if people feel strongly that it's strictly required).
The same is true for `FromReflect`. We may decide to add an
implementation there as well, but it's likely out-of-scope of this PR.
## Testing
You can test locally by running:
```
cargo test --package bevy_reflect --all-features
```
---
## Showcase
You can now pass around a `DynamicFunction` as a `dyn PartialReflect`!
This also means you can use it as a field on a reflected type without
having to ignore it (though you do need to opt out of `FromReflect`).
```rust
#[derive(Reflect)]
#[reflect(from_reflect = false)]
struct ClickEvent {
callback: DynamicFunction<'static>,
}
let event: Box<dyn Struct> = Box::new(ClickEvent {
callback: (|| println!("Clicked!")).into_function(),
});
// We can access our `DynamicFunction` as a `dyn PartialReflect`
let callback: &dyn PartialReflect = event.field("callback").unwrap();
// And access function-related methods via the new `Function` trait
let ReflectRef::Function(callback) = callback.reflect_ref() else {
unreachable!()
};
// Including calling the function
callback.reflect_call(ArgList::new()).unwrap(); // Prints: Clicked!
```
# Objective
Add examples for manipulating sprites and meshes by either mutating the
handle or direct manipulation of the asset, as described in #15056.
Closes#3130.

- Adopts the parts of #15118 that are complete, and updates the branch
so it can be merged.
- There were a few conflicts, let me know if I misjudged any of 'em.

[recommendation](https://github.com/bevyengine/bevy/issues/15059#issuecomment-2349263900)
seems well-taken, let's do this crate by crate now that @BD103 has done
the lion's share of this!
(Relates to, but doesn't yet completely finish #15059.)
Crates this _doesn't_ cover:
- bevy_input
- bevy_gilrs
- bevy_window
- bevy_winit
- bevy_state
- bevy_render
- bevy_picking
- bevy_core_pipeline
- bevy_sprite
- bevy_text
- bevy_pbr
- bevy_ui
- bevy_gltf
- bevy_gizmos
- bevy_dev_tools
- bevy_internal
- bevy_dylib

# Objective
There may be times where a function in the `FunctionRegistry` doesn't
need to be fully retrieved. A user may just need to call it with a set
of arguments.
We should provide a shortcut for doing this.
## Solution
Add the `FunctionRegistry::call` method to directly call a function in
the registry with the given name and arguments.
## Testing
You can test locally by running:
```
cargo test --package bevy_reflect --all-features
```
No hard feelings if you don't want to make this change. This is just
something I stumbled over in my very first read of the `bevy_ecs` crate.
# Objective
- the general goal here is to improve DX slightly
- make the code easier to read in general. The previous names make the
code harder to read, especially since they are so similar.
## Solution
- choose more specific names for the fields
- `index_iter` -> `freelist_indices` : "freelist" is a well established
term in the rest of the docs in this module, so we might want to reuse
it
- `index_range` -> `new_indices` : Nothing besides the doc comment
stated that these indices were actually new/fresh
## Testing
Note that the fields are private so that this is no breaking change.
They are also only used in this one module.
# Objective
- Fixes#15319
- Fixes#15317
## Solution
- Updated CI task to check for _any_ `bevy_*` crates, rather than just
`bevy_internal`

# Objective
- Intended to resolve https://github.com/bevyengine/bevy/issues/15290.
- Fix four duplicate `DragEnd` firing when drag finished.
- Fix redundant `DragStart` firing when dragging across pick-able
entities.
- Fix `Click` coming after `Drop` and obliterating finished drag
interactions.
Big thanks to B. Reinhart for testing picking in their codebase and
identifying these issues early.
## Solution
- Fix press & drag state being cleared after the first entity is read
from the hover map on pointer release, rather than after all entities
are read. This caused only the first hovered entity to receive `Up` and
`Click` events.
- Fixes `Down` being determined using the `previous_hover_map` rather
than `hover_map`, a regression compared to `bevy_mod_picking`. I think
this is what was messing up drag events.
- Fixes and issue where `PointerEnd` would fire multiple times and
`PointerStart` would fire when dragging onto a new entity.
- Re-orders events to make them easier to handle. `Out` now fired before
`DragLeave` and `Click/Up` now fire before `DragDrop`.
- Generally refactors the picking event code to be more clean and sane.
## Testing
These changes are currently sporadically tested.
# Objective
- Remove an int2ptr cast in `bevy_ptr::dangling_with_align`
- This is flagged by MIRI unless `-Zmiri-permissive-provenance` is used
(like in CI)
- Remove `-Zmiri-permissive-provenance` in CI
## Solution
- Create the raw pointer like
[`std::ptr::without_provenance`](https://doc.rust-lang.org/stable/std/ptr/fn.without_provenance_mut.html)
does, i.e. by starting from a null pointer.
