# Objective
- Fixes#11187
## Solution
- Rename the `AddChild` struct to `PushChild`
- Rename the `AddChildInPlace` struct to `PushChildInPlace`
## Migration Guide
The struct `AddChild` has been renamed to `PushChild`, and the struct
`AddChildInPlace` has been renamed to `PushChildInPlace`.
# Objective

## Solution
- Re-add lost negation
# Objective
- Fixes#11119
## Solution
- Creation of the serialize feature to ui
---
## Changelog
### Changed
- Changed all the structs that implement Serialize and Deserialize to
only implement when feature is on
## Migration Guide
- If you want to use serialize and deserialize with types from bevy_ui,
you need to use the feature serialize in your TOML
```toml
[dependencies.bevy]
features = ["serialize"]
```
# Objective
Fixes Gizmos crash due to the persistence policy being set to `Unload`
## Solution
Change it to `Keep`
Co-authored-by: rqg <ranqingguo318@gmail.com>
# Objective
- No point in keeping Meshes/Images in RAM once they're going to be sent
to the GPU, and kept in VRAM. This saves a _significant_ amount of
memory (several GBs) on scenes like bistro.
- References
- https://github.com/bevyengine/bevy/pull/1782
- https://github.com/bevyengine/bevy/pull/8624
## Solution
- Augment RenderAsset with the capability to unload the underlying asset
after extracting to the render world.
- Mesh/Image now have a cpu_persistent_access field. If this field is
RenderAssetPersistencePolicy::Unload, the asset will be unloaded from
Assets<T>.
- A new AssetEvent is sent upon dropping the last strong handle for the
asset, which signals to the RenderAsset to remove the GPU version of the
asset.
---
## Changelog
- Added `AssetEvent::NoLongerUsed` and
`AssetEvent::is_no_longer_used()`. This event is sent when the last
strong handle of an asset is dropped.
- Rewrote the API for `RenderAsset` to allow for unloading the asset
data from the CPU.
- Added `RenderAssetPersistencePolicy`.
- Added `Mesh::cpu_persistent_access` for memory savings when the asset
is not needed except for on the GPU.
- Added `Image::cpu_persistent_access` for memory savings when the asset
is not needed except for on the GPU.
- Added `ImageLoaderSettings::cpu_persistent_access`.
- Added `ExrTextureLoaderSettings`.
- Added `HdrTextureLoaderSettings`.
## Migration Guide
- Asset loaders (GLTF, etc) now load meshes and textures without
`cpu_persistent_access`. These assets will be removed from
`Assets<Mesh>` and `Assets<Image>` once `RenderAssets<Mesh>` and
`RenderAssets<Image>` contain the GPU versions of these assets, in order
to reduce memory usage. If you require access to the asset data from the
CPU in future frames after the GLTF asset has been loaded, modify all
dependent `Mesh` and `Image` assets and set `cpu_persistent_access` to
`RenderAssetPersistencePolicy::Keep`.
- `Mesh` now requires a new `cpu_persistent_access` field. Set it to
`RenderAssetPersistencePolicy::Keep` to mimic the previous behavior.
- `Image` now requires a new `cpu_persistent_access` field. Set it to
`RenderAssetPersistencePolicy::Keep` to mimic the previous behavior.
- `MorphTargetImage::new()` now requires a new `cpu_persistent_access`
parameter. Set it to `RenderAssetPersistencePolicy::Keep` to mimic the
previous behavior.
- `DynamicTextureAtlasBuilder::add_texture()` now requires that the
`TextureAtlas` you pass has an `Image` with `cpu_persistent_access:
RenderAssetPersistencePolicy::Keep`. Ensure you construct the image
properly for the texture atlas.
- The `RenderAsset` trait has significantly changed, and requires
adapting your existing implementations.
- The trait now requires `Clone`.
- The `ExtractedAsset` associated type has been removed (the type itself
is now extracted).
- The signature of `prepare_asset()` is slightly different
- A new `persistence_policy()` method is now required (return
RenderAssetPersistencePolicy::Unload to match the previous behavior).
- Match on the new `NoLongerUsed` variant for exhaustive matches of
`AssetEvent`.
# Objective
- We want to use `static_assertions` to perform precise compile time
checks at testing time. In this PR, we add those checks to make sure
that `EntityHashMap` and `PreHashMap` are `Clone` (and we replace the
more clumsy previous tests)
- Fixes#11181
(will need to be rebased once
https://github.com/bevyengine/bevy/pull/11178 is merged)

# Objective
Lightmaps, textures that store baked global illumination, have been a
mainstay of real-time graphics for decades. Bevy currently has no
support for them, so this pull request implements them.
## Solution
The new `Lightmap` component can be attached to any entity that contains
a `Handle<Mesh>` and a `StandardMaterial`. When present, it will be
applied in the PBR shader. Because multiple lightmaps are frequently
packed into atlases, each lightmap may have its own UV boundaries within
its texture. An `exposure` field is also provided, to control the
brightness of the lightmap.
Note that this PR doesn't provide any way to bake the lightmaps. That
can be done with [The Lightmapper] or another solution, such as Unity's
Bakery.
---
## Changelog
### Added
* A new component, `Lightmap`, is available, for baked global
illumination. If your mesh has a second UV channel (UV1), and you attach
this component to the entity with that mesh, Bevy will apply the texture
referenced in the lightmap.

This PR is part of a project aimed at improving the API documentation of
`bevy_hierarchy`. Other PRs will be based on this.
This PR in particular is also an experiment in providing a high level
overview of the tools provided by a Bevy plugin/crate. It also provides
general information about universal invariants, so statement repetition
in crate items can be dramatically reduced.
## Other changes

Supersedes #10888.
# Objective
Closes#10821
## Solution
- Replaced
[JamesIves/github-pages-deploy-action](https://github.com/JamesIves/github-pages-deploy-action)
with
[actions/upload-pages-artifact](https://github.com/actions/upload-pages-artifact)
and [actions/deploy-pages](https://github.com/actions/deploy-pages).
## Notes
- I made this workflow possible to run through dispatch
(`workflow_dispatch`), in case something goes wrong.
- I restricted the permissions to just the things Github Pages needs.
- I made it so that only one deployments can happen at a time, the other
deployment requests will be queued up and the latest one will be run.
# Objective
- `EntityHashMap`, `EntityHashSet` and `PreHashMap` are currently not
Cloneable because of a missing trivial `Clone` bound for `EntityHash`
and `PreHash`. This PR makes them Cloneable.
(the parent struct `hashbrown::HashMap` requires the `HashBuilder` to be
`Clone` for the `HashMap` to be `Clone`, see:
https://github.com/rust-lang/hashbrown/blob/master/src/map.rs#L195)
## Solution
- Add a `Clone` bound to `PreHash` and `EntityHash`

# Objective
`bevy_math` re-exports Glam, but doesn't have a feature for enabling
`approx` for it. Many projects (including some of Bevy's own crates)
need `approx`, and it'd be nice if you didn't have to manually add Glam
to specify the feature for it.
## Solution
Add an `approx` feature to `bevy_math`.
# Objective
I often need a direction along one of the cartesian XYZ axes, and it
currently requires e.g. `Direction2d::from_normalized(Vec2::X)`, which
isn't ideal.
## Solution
Add direction constants that are the same as the ones on Glam types. I
also copied the doc comment format "A unit vector pointing along the ...
axis", but I can change it if there's a better wording for directions.
# Objective
I frequently encounter cases where I need to get the opposite direction.
This currently requires something like
`Direction2d::from_normalized(-*direction)`, which is very inconvenient.
## Solution
Implement `Neg` for `Direction2d` and `Direction3d`.
# Objective
If you have multiple windows, there is no way to determine which window
a `TouchInput` event applies to. This fixes that.
## Solution
- Add the window entity directly to `TouchInput`, just like the other
input events.
- Fixes#6011.
## Migration Guide
+ Add a `window` field when constructing or destructuring a `TouchInput`
struct.
This expands upon https://github.com/bevyengine/bevy/pull/11134.
I found myself needing `tonemapping_pipeline_key` for some custom 2d
draw functions. #11134 exported the 3d version of
`tonemapping_pipeline_key` and this PR exports the 2d version. I also
made `alpha_mode_pipeline_key` public for good measure.
# Objective
When panic handler prints to stdout instead of stderr, I've observed two
outcomes with this PR test #11169:
- Sometimes output is mixed up, so it is not clear where one record ends
and another stards
- Sometimes output is lost
## Solution
Print to stderr.
## Changelog
- Panic handler in `LogPlugin` writes to stderr instead of stdin.
# Objective
`SystemName` might be useful in systems which accept `&mut World`.
## Solution
- `impl ExclusiveSystemParam for SystemName`
- move `SystemName` into a separate file, because it no longer belongs
to a file which defines `SystemParam`
- add a test for new impl, and for existing impl
## Changelog
- `impl ExclusiveSystemParam for SystemName`
Turns out whenever a normal prepass was active (which includes whenever
you use SSAO) we were attempting to read the normals from the prepass
for the specular transmissive material. Since transmissive materials
don't participate in the prepass (unlike opaque materials) we were
reading the normals from “behind” the mesh, producing really weird
visual results.
# Objective
- Fixes#11112.
## Solution
- We introduce a new `READS_VIEW_TRANSMISSION_TEXTURE` mesh pipeline
key;
- We set it whenever the material properties has the
`reads_view_transmission_texture` flag set; (i.e. the material is
transmissive)
- If this key is set we prevent the reading of normals from the prepass,
by not setting the `LOAD_PREPASS_NORMALS` shader def.
---
## Changelog
### Fixed
- Specular transmissive materials no longer attempt to erroneously load
prepass normals, and now work correctly even with the normal prepass
active (e.g. when using SSAO)
# Objective
- Refactor collide code and add tests.
## Solution
- Rebase the changes made in #4485.
Co-authored-by: Eduardo Canellas de Oliveira <eduardo.canellas@bemobi.com>
# Objective
There are a lot of doctests that are `ignore`d for no documented reason.
And that should be fixed.
## Solution
I searched the bevy repo with the regex ` ```[a-z,]*ignore ` in order to
find all `ignore`d doctests. For each one of the `ignore`d doctests, I
did the following steps:
1. Attempt to remove the `ignored` attribute while still passing the
test. I did this by adding hidden dummy structs and imports.
2. If step 1 doesn't work, attempt to replace the `ignored` attribute
with the `no_run` attribute while still passing the test.
3. If step 2 doesn't work, keep the `ignored` attribute but add
documentation for why the `ignored` attribute was added.

# Objective
Fixes#11050
Rename ArchetypeEntity::entity to ArchetypeEntity::id to be consistent
with `EntityWorldMut`, `EntityMut` and `EntityRef`.
## Migration Guide
The method `ArchetypeEntity::entity` has been renamed to
`ArchetypeEntity::id`
# Objective
- There is an warning about non snake case on system_param.rs generated
by a macro
## Solution
- Allow non snake case on the function at fault
# Objective
Implement `ExclusiveSystemParam` for `PhantomData`.
For the same reason `SystemParam` impl exists: to simplify writing
generic code.
786abbf3f5/crates/bevy_ecs/src/system/system_param.rs (L1557)
Also for consistency.
## Solution
`impl ExclusiveSystemParam for PhantomData`.
## Changelog
Added: PhantomData<T> now implements ExclusiveSystemParam.
# Objective
Mostly for consistency.
## Solution
```rust
impl ExclusiveSystemParam for WorldId
```
- Also add a test for `SystemParam for WorldId`
## Changelog
Added: Worldd now implements ExclusiveSystemParam.
# Objective
- Custom render passes, or future passes in the engine (such as
https://github.com/bevyengine/bevy/pull/10164) need a better way to know
and indicate to the core passes whether the view color/depth/prepass
attachments have been cleared or not yet this frame, to know if they
should clear it themselves or load it.
## Solution
- For all render targets (depth textures, shadow textures, prepass
textures, main textures) use an atomic bool to track whether or not each
texture has been cleared this frame. Abstracted away in the new
ColorAttachment and DepthAttachment wrappers.
---
## Changelog
- Changed `ViewTarget::get_color_attachment()`, removed arguments.
- Changed `ViewTarget::get_unsampled_color_attachment()`, removed
arguments.
- Removed `Camera3d::clear_color`.
- Removed `Camera2d::clear_color`.
- Added `Camera::clear_color`.
- Added `ExtractedCamera::clear_color`.
- Added `ColorAttachment` and `DepthAttachment` wrappers.
- Moved `ClearColor` and `ClearColorConfig` from
`bevy::core_pipeline::clear_color` to `bevy::render::camera`.
- Core render passes now track when a texture is first bound as an
attachment in order to decide whether to clear or load it.
## Migration Guide
- Remove arguments to `ViewTarget::get_color_attachment()` and
`ViewTarget::get_unsampled_color_attachment()`.
- Configure clear color on `Camera` instead of on `Camera3d` and
`Camera2d`.
- Moved `ClearColor` and `ClearColorConfig` from
`bevy::core_pipeline::clear_color` to `bevy::render::camera`.
- `ViewDepthTexture` must now be created via the `new()` method

# Objective
Provide an example of how to achieve pixel-perfect "grid snapping" in 2D
via rendering to a texture. This is a common use case in retro pixel art
game development.
## Solution
Render sprites to a canvas via a Camera, then use another (scaled up)
Camera to render the resulting canvas to the screen. This example is
based on the `3d/render_to_texture.rs` example. Furthermore, this
example demonstrates mixing retro-style graphics with high-resolution
graphics, as well as pixel-snapped rendering of a
`MaterialMesh2dBundle`.
# Objective
- Provides an alternate solution to the one implemented in #10791
without breaking changes.
## Solution
- Changes the bounds of macro-generated `TypePath` implementations to
universally ignore the types of fields, rather than use the same bounds
as other implementations. I think this is a more holistic solution than
#10791 because it totally erases the finicky bounds we currently
generate, helping to untangle the reflection trait system.
# Objective
- Make the implementation order consistent between all sources to fit
the order in the trait.
## Solution
- Change the implementation order.
Matches versioning & features from other Cargo.toml files in the
project.
# Objective
Resolves#10932
## Solution
Added smallvec to the bevy_utils cargo.toml and added a line to
re-export the crate. Target version and features set to match what's
used in the other bevy crates.
