Migrate cameras to required components (#15641)
# Objective Yet another PR for migrating stuff to required components. This time, cameras! ## Solution As per the [selected proposal](https://hackmd.io/tsYID4CGRiWxzsgawzxG_g#Combined-Proposal-1-Selected), deprecate `Camera2dBundle` and `Camera3dBundle` in favor of `Camera2d` and `Camera3d`. Adding a `Camera` without `Camera2d` or `Camera3d` now logs a warning, as suggested by Cart [on Discord](https://discord.com/channels/691052431525675048/1264881140007702558/1291506402832945273). I would personally like cameras to work a bit differently and be split into a few more components, to avoid some footguns and confusing semantics, but that is more controversial, and shouldn't block this core migration. ## Testing I ran a few 2D and 3D examples, and tried cameras with and without render graphs. --- ## Migration Guide `Camera2dBundle` and `Camera3dBundle` have been deprecated in favor of `Camera2d` and `Camera3d`. Inserting them will now also insert the other components required by them automatically. |

bevy_asset: Improve NestedLoader API (#15509)
# Objective
The `NestedLoader` API as it stands right now is somewhat lacking:
- It consists of several types `NestedLoader`, `UntypedNestedLoader`,
`DirectNestedLoader`, and `UntypedDirectNestedLoader`, where a typestate
pattern on `NestedLoader` would be make it more obvious what it does,
and allow centralising the documentation
- The term "untyped" in the asset loader code is overloaded. It can mean
either:
- we have literally no idea what the type of this asset will be when we
load it (I dub this "unknown type")
- we know what type of asset it will be, but we don't know it statically
- we only have a TypeId (I dub this "dynamic type" / "erased")
- There is no way to get an `UntypedHandle` (erased) given a `TypeId`
## Solution
Changes `NestedLoader` into a type-state pattern, adding two type
params:
- `T` determines the typing
- `StaticTyped`, the default, where you pass in `A` statically into `fn
load<A>() -> ..`
- `DynamicTyped`, where you give a `TypeId`, giving you a
`UntypedHandle`
- `UnknownTyped`, where you have literally no idea what type of asset
you're loading, giving you a `Handle<LoadedUntypedAsset>`
- `M` determines the "mode" (bikeshedding TBD, I couldn't come up with a
better name)
- `Deferred`, the default, won't load the asset when you call `load`,
but it does give you a `Handle` to it (this is nice since it can be a
sync fn)
- `Immediate` will load the asset as soon as you call it, and give you
access to it, but you must be in an async context to call it
Changes some naming of internals in `AssetServer` to fit the new
definitions of "dynamic type" and "unknown type". Note that I didn't do
a full pass over this code to keep the diff small. That can probably be
done in a new PR - I think the definiton I laid out of unknown type vs.
erased makes it pretty clear where each one applies.
<details>
<summary>Old issue</summary>
The only real problem I have with this PR is the requirement to pass in
`type_name` (from `core::any::type_name`) into Erased. Users might not
have that type name, only the ID, and it just seems sort of weird to
*have* to give an asset type name. However, the reason we need it is
because of this:
```rs
pub(crate) fn get_or_create_path_handle_erased(
&mut self,
path: AssetPath<'static>,
type_id: TypeId,
type_name: &str,
loading_mode: HandleLoadingMode,
meta_transform: Option<MetaTransform>,
) -> (UntypedHandle, bool) {
let result = self.get_or_create_path_handle_internal(
path,
Some(type_id),
loading_mode,
meta_transform,
);
// it is ok to unwrap because TypeId was specified above
unwrap_with_context(result, type_name).unwrap()
}
pub(crate) fn unwrap_with_context<T>(
result: Result<T, GetOrCreateHandleInternalError>,
type_name: &str,
) -> Option<T> {
match result {
Ok(value) => Some(value),
Err(GetOrCreateHandleInternalError::HandleMissingButTypeIdNotSpecified) => None,
Err(GetOrCreateHandleInternalError::MissingHandleProviderError(_)) => {
panic!("Cannot allocate an Asset Handle of type '{type_name}' because the asset type has not been initialized. \
Make sure you have called app.init_asset::<{type_name}>()")
}
}
}
```
This `unwrap_with_context` is literally the only reason we need the
`type_name`. Potentially, this can be turned into an `impl
Into<Option<&str>>`, and output a different error message if the type
name is missing. Since if we are loading an asset where we only know the
type ID, by definition we can't output that error message, since we
don't have the type name. I'm open to suggestions on this.
</details>
## Testing
Not sure how to test this, since I kept most of the actual NestedLoader
logic the same. The only new API is loading an `UntypedHandle` when in
the `DynamicTyped, Immediate` state.
## Migration Guide
Code which uses `bevy_asset`'s `LoadContext::loader` / `NestedLoader`
will see some naming changes:
- `untyped` is replaced by `with_unknown_type`
- `with_asset_type` is replaced by `with_static_type`
- `with_asset_type_id` is replaced by `with_dynamic_type`
- `direct` is replaced by `immediate` (the opposite of "immediate" is
"deferred")

Cleanup unneeded lifetimes in bevy_asset (#15546)
# Objective Fixes #15541 A bunch of lifetimes were added during the Assets V2 rework, but after moving to async traits in #12550 they can be elided. That PR mentions that this might be the case, but apparently it wasn't followed up on at the time. ~~I ended up grepping for `<'a` and finding a similar case in `bevy_reflect` which I also fixed.~~ (edit: that one was needed apparently) Note that elided lifetimes are unstable in `impl Trait`. If that gets stabilized then we can elide even more. ## Solution Remove the extra lifetimes. ## Testing Everything still compiles. If I have messed something up there is a small risk that some user code stops compiling, but all the examples still work at least. --- ## Migration Guide The traits `AssetLoader`, `AssetSaver` and `Process` traits from `bevy_asset` now use elided lifetimes. If you implement these then remove the named lifetime. |

Migrate visibility to required components (#15474)
# Objective The next step in the migration to required components: Deprecate `VisibilityBundle` and make `Visibility` require `InheritedVisibility` and `ViewVisibility`, as per the [chosen proposal](https://hackmd.io/@bevy/required_components/%2FcO7JPSAQR5G0J_j5wNwtOQ). ## Solution Deprecate `VisibilityBundle` and make `Visibility` require `InheritedVisibility` and `ViewVisibility`. I chose not to deprecate `SpatialBundle` yet, as doing so would mean that we need to manually add `Visibility` to a bunch of places. It will be nicer once meshes, sprites, lights, fog, and cameras have been migrated, since they will require `Transform` and `Visibility` and therefore not need manually added defaults for them. --- ## Migration Guide Replace all insertions of `VisibilityBundle` with the `Visibility` component. The other components required by it will now be inserted automatically. |

Migrate bevy_transform to required components (#14964)
The first step in the migration to required components! This PR removes `GlobalTransform` from all user-facing code, since it's now added automatically wherever `Transform` is used. ## Testing - None of the examples I tested were broken, and I assume breaking transforms in any way would be visible *everywhere* --- ## Changelog - Make `Transform` require `GlobalTransform` ~~- Remove `GlobalTransform` from all engine bundles~~ - Remove in-engine insertions of GlobalTransform and TransformBundle - Deprecate `TransformBundle` - update docs to reflect changes ## Migration Guide Replace all insertions of `GlobalTransform` and/or `TransformBundle` with `Transform` alone. --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com> Co-authored-by: Tim <JustTheCoolDude@gmail.com> |

Optimize common usages of AssetReader (#14082)
# Objective
The `AssetReader` trait allows customizing the behavior of fetching
bytes for an `AssetPath`, and expects implementors to return `dyn
AsyncRead + AsyncSeek`. This gives implementors of `AssetLoader` great
flexibility to tightly integrate their asset loading behavior with the
asynchronous task system.
However, almost all implementors of `AssetLoader` don't use the async
functionality at all, and just call `AsyncReadExt::read_to_end(&mut
Vec<u8>)`. This is incredibly inefficient, as this method repeatedly
calls `poll_read` on the trait object, filling the vector 32 bytes at a
time. At my work we have assets that are hundreds of megabytes which
makes this a meaningful overhead.
## Solution
Turn the `Reader` type alias into an actual trait, with a provided
method `read_to_end`. This provided method should be more efficient than
the existing extension method, as the compiler will know the underlying
type of `Reader` when generating this function, which removes the
repeated dynamic dispatches and allows the compiler to make further
optimizations after inlining. Individual implementors are able to
override the provided implementation -- for simple asset readers that
just copy bytes from one buffer to another, this allows removing a large
amount of overhead from the provided implementation.
Now that `Reader` is an actual trait, I also improved the ergonomics for
implementing `AssetReader`. Currently, implementors are expected to box
their reader and return it as a trait object, which adds unnecessary
boilerplate to implementations. This PR changes that trait method to
return a pseudo trait alias, which allows implementors to return `impl
Reader` instead of `Box<dyn Reader>`. Now, the boilerplate for boxing
occurs in `ErasedAssetReader`.
## Testing
I made identical changes to my company's fork of bevy. Our app, which
makes heavy use of `read_to_end` for asset loading, still worked
properly after this. I am not aware if we have a more systematic way of
testing asset loading for correctness.
---
## Migration Guide
The trait method `bevy_asset::io::AssetReader::read` (and `read_meta`)
now return an opaque type instead of a boxed trait object. Implementors
of these methods should change the type signatures appropriately
```rust
impl AssetReader for MyReader {
// Before
async fn read<'a>(&'a self, path: &'a Path) -> Result<Box<Reader<'a>>, AssetReaderError> {
let reader = // construct a reader
Box::new(reader) as Box<Reader<'a>>
}
// After
async fn read<'a>(&'a self, path: &'a Path) -> Result<impl Reader + 'a, AssetReaderError> {
// create a reader
}
}
```
`bevy::asset::io::Reader` is now a trait, rather than a type alias for a
trait object. Implementors of `AssetLoader::load` will need to adjust
the method signature accordingly
```rust
impl AssetLoader for MyLoader {
async fn load<'a>(
&'a self,
// Before:
reader: &'a mut bevy::asset::io::Reader,
// After:
reader: &'a mut dyn bevy::asset::io::Reader,
_: &'a Self::Settings,
load_context: &'a mut LoadContext<'_>,
) -> Result<Self::Asset, Self::Error> {
}
```
Additionally, implementors of `AssetReader` that return a type
implementing `futures_io::AsyncRead` and `AsyncSeek` might need to
explicitly implement `bevy::asset::io::Reader` for that type.
```rust
impl bevy::asset::io::Reader for MyAsyncReadAndSeek {}
```

Make LoadContext use the builder pattern for loading dependent assets (#13465)
# Objective - Fixes #13445. ## Solution - Removes all `load_` methods from `LoadContext`. - Introduces `fn loader()` which returns a builder. ## Testing - I've tested with `cargo test --package=bevy_asset` and run the two relevant examples (`asset_processing` & `asset_decompression`). --- ## Changelog - Replaced all `load_` methods on `LoadContext` with the new `loader()` pattern. ## Migration Guide - Several LoadContext method calls will need to be updated: - `load_context.load_with_settings(path, settings)` => `load_context.loader().with_settings(settings).load(path)` - `load_context.load_untyped(path)` => `load_context.loader().untyped().load(path)` - `load_context.load_direct(path)` => `load_context.loader().direct().load(path)` - `load_context.load_direct_untyped(path)` => `load_context.loader().direct().untyped().load(path)` - `load_context.load_direct_with_settings(path, settings)` => `load_context.loader().with_settings(settings).direct().load(path)` - `load_context.load_direct_with_reader(reader, path)` => `load_context.loader().direct().with_reader(reader).load(path)` - `load_context.load_direct_with_reader_and_settings(reader, path, settings)` => `load_context.loader().with_settings(settings).direct().with_reader(reader).load(path)` - `load_context.load_direct_untyped_with_reader(reader, path)` => `load_context.loader().direct().with_reader(reader).untyped().load(path)` --- CC @alice-i-cecile / @bushrat011899 Examples: ```rust load_context.loader() .with_asset_type::<A>() .with_asset_type_id(TypeId::of::<A>()) .with_settings(|mut settings| { settings.key = value; }) // Then, for a Handle<A>: .load::<A>() // Or, for a Handle<LoadedUntypedAsset>: .untyped() .load() // Or, to load an `A` directly: .direct() .load::<A>() .await // Or, to load an `ErasedLoadedAsset` directly: .direct() .untyped() .load() .await ``` |

Add more load_direct implementations (#13415)
# Objective - Introduce variants of `LoadContext::load_direct` which allow picking asset type & configuring settings. - Fixes #12963. ## Solution - Implements `ErasedLoadedAsset::downcast` and adds some accessors to `LoadedAsset<A>`. - Changes `load_direct`/`load_direct_with_reader` to be typed, and introduces `load_direct_untyped`/`load_direct_untyped_with_reader`. - Introduces `load_direct_with_settings` and `load_direct_with_reader_and_settings`. ## Testing - I've run cargo test and played with the examples which use `load_direct`. - I also extended the `asset_processing` example to use the new typed version of `load_direct` and use `load_direct_with_settings`. --- ## Changelog - Introduced new `load_direct` methods in `LoadContext` to allow specifying type & settings ## Migration Guide - `LoadContext::load_direct` has been renamed to `LoadContext::load_direct_untyped`. You may find the new `load_direct` is more appropriate for your use case (and the migration may only be moving one type parameter). - `LoadContext::load_direct_with_reader` has been renamed to `LoadContext::load_direct_untyped_with_reader`. --- This might not be an obvious win as a solution because it introduces quite a few new `load_direct` alternatives - but it does follow the existing pattern pretty well. I'm very open to alternatives. 😅 |

Use async-fn in traits rather than BoxedFuture (#12550)
# Objective
Simplify implementing some asset traits without Box::pin(async move{})
shenanigans.
Fixes (in part) https://github.com/bevyengine/bevy/issues/11308
## Solution
Use async-fn in traits when possible in all traits. Traits with return
position impl trait are not object safe however, and as AssetReader and
AssetWriter are both used with dynamic dispatch, you need a Boxed
version of these futures anyway.
In the future, Rust is [adding
](https://blog.rust-lang.org/2023/12/21/async-fn-rpit-in-traits.html)proc
macros to generate these traits automatically, and at some point in the
future dyn traits should 'just work'. Until then.... this seemed liked
the right approach given more ErasedXXX already exist, but, no clue if
there's plans here! Especially since these are public now, it's a bit of
an unfortunate API, and means this is a breaking change.
In theory this saves some performance when these traits are used with
static dispatch, but, seems like most code paths go through dynamic
dispatch, which boxes anyway.
I also suspect a bunch of the lifetime annotations on these function
could be simplified now as the BoxedFuture was often the only thing
returned which needed a lifetime annotation, but I'm not touching that
for now as traits + lifetimes can be so tricky.
This is a revival of
[pull/11362](https://github.com/bevyengine/bevy/pull/11362) after a
spectacular merge f*ckup, with updates to the latest Bevy. Just to recap
some discussion:
- Overall this seems like a win for code quality, especially when
implementing these traits, but a loss for having to deal with ErasedXXX
variants.
- `ConditionalSend` was the preferred name for the trait that might be
Send, to deal with wasm platforms.
- When reviewing be sure to disable whitespace difference, as that's 95%
of the PR.
## Changelog
- AssetReader, AssetWriter, AssetLoader, AssetSaver and Process now use
async-fn in traits rather than boxed futures.
## Migration Guide
- Custom implementations of AssetReader, AssetWriter, AssetLoader,
AssetSaver and Process should switch to async fn rather than returning a
bevy_utils::BoxedFuture.
- Simultaniously, to use dynamic dispatch on these traits you should
instead use dyn ErasedXXX.

Added Method to Allow Pipelined Asset Loading (#10565)
# Objective - Fixes #10518 ## Solution I've added a method to `LoadContext`, `load_direct_with_reader`, which mirrors the behaviour of `load_direct` with a single key difference: it is provided with the `Reader` by the caller, rather than getting it from the contained `AssetServer`. This allows for an `AssetLoader` to process its `Reader` stream, and then directly hand the results off to the `LoadContext` to handle further loading. The outer `AssetLoader` can control how the `Reader` is interpreted by providing a relevant `AssetPath`. For example, a Gzip decompression loader could process the asset `images/my_image.png.gz` by decompressing the bytes, then handing the decompressed result to the `LoadContext` with the new path `images/my_image.png.gz/my_image.png`. This intuitively reflects the nature of contained assets, whilst avoiding unintended behaviour, since the generated path cannot be a real file path (a file and folder of the same name cannot coexist in most file-systems). ```rust #[derive(Asset, TypePath)] pub struct GzAsset { pub uncompressed: ErasedLoadedAsset, } #[derive(Default)] pub struct GzAssetLoader; impl AssetLoader for GzAssetLoader { type Asset = GzAsset; type Settings = (); type Error = GzAssetLoaderError; fn load<'a>( &'a self, reader: &'a mut Reader, _settings: &'a (), load_context: &'a mut LoadContext, ) -> BoxedFuture<'a, Result<Self::Asset, Self::Error>> { Box::pin(async move { let compressed_path = load_context.path(); let file_name = compressed_path .file_name() .ok_or(GzAssetLoaderError::IndeterminateFilePath)? .to_string_lossy(); let uncompressed_file_name = file_name .strip_suffix(".gz") .ok_or(GzAssetLoaderError::IndeterminateFilePath)?; let contained_path = compressed_path.join(uncompressed_file_name); let mut bytes_compressed = Vec::new(); reader.read_to_end(&mut bytes_compressed).await?; let mut decoder = GzDecoder::new(bytes_compressed.as_slice()); let mut bytes_uncompressed = Vec::new(); decoder.read_to_end(&mut bytes_uncompressed)?; // Now that we have decompressed the asset, let's pass it back to the // context to continue loading let mut reader = VecReader::new(bytes_uncompressed); let uncompressed = load_context .load_direct_with_reader(&mut reader, contained_path) .await?; Ok(GzAsset { uncompressed }) }) } fn extensions(&self) -> &[&str] { &["gz"] } } ``` Because this example is so prudent, I've included an `asset_decompression` example which implements this exact behaviour: ```rust fn main() { App::new() .add_plugins(DefaultPlugins) .init_asset::<GzAsset>() .init_asset_loader::<GzAssetLoader>() .add_systems(Startup, setup) .add_systems(Update, decompress::<Image>) .run(); } fn setup(mut commands: Commands, asset_server: Res<AssetServer>) { commands.spawn(Camera2dBundle::default()); commands.spawn(( Compressed::<Image> { compressed: asset_server.load("data/compressed_image.png.gz"), ..default() }, Sprite::default(), TransformBundle::default(), VisibilityBundle::default(), )); } fn decompress<A: Asset>( mut commands: Commands, asset_server: Res<AssetServer>, mut compressed_assets: ResMut<Assets<GzAsset>>, query: Query<(Entity, &Compressed<A>)>, ) { for (entity, Compressed { compressed, .. }) in query.iter() { let Some(GzAsset { uncompressed }) = compressed_assets.remove(compressed) else { continue; }; let uncompressed = uncompressed.take::<A>().unwrap(); commands .entity(entity) .remove::<Compressed<A>>() .insert(asset_server.add(uncompressed)); } } ``` A key limitation to this design is how to type the internally loaded asset, since the example `GzAssetLoader` is unaware of the internal asset type `A`. As such, in this example I store the contained asset as an `ErasedLoadedAsset`, and leave it up to the consumer of the `GzAsset` to handle typing the final result, which is the purpose of the `decompress` system. This limitation can be worked around by providing type information to the `GzAssetLoader`, such as `GzAssetLoader<Image, ImageAssetLoader>`, but this would require registering the asset loader for every possible decompression target. Aside from this limitation, nested asset containerisation works as an end user would expect; if the user registers a `TarAssetLoader`, and a `GzAssetLoader`, then they can load assets with compound containerisation, such as `images.tar.gz`. --- ## Changelog - Added `LoadContext::load_direct_with_reader` - Added `asset_decompression` example ## Notes - While I believe my implementation of a Gzip asset loader is reasonable, I haven't included it as a public feature of `bevy_asset` to keep the scope of this PR as focussed as possible. - I have included `flate2` as a `dev-dependency` for the example; it is not included in the main dependency graph. |
