# Objective
avoid panics from `calculate_bounds` systems if entities are despawned
in PostUpdate.
there's a running general discussion (#10166) about command panicking.
in the meantime we may as well fix up some cases where it's clear a
failure to insert is safe.
## Solution
change `.insert(aabb)` to `.try_insert(aabb)`

Currently the following code fails due to a missing `TypePath` bound:
```rust
#[derive(Reflect)] struct Foo<T>(T);
#[derive(Reflect)] struct Bar<T>(Foo<T>);
#[derive(Reflect)] struct Baz<T>(Bar<Foo<T>>);
```
## Solution
Add `TypePath` to the per-field bounds instead of _just_ the generic
type parameter bounds.
### Related Work
It should be noted that #9046 would help make these kinds of issues
easier to work around and/or avoid entirely.
---
## Changelog
- Fixes missing `TypePath` requirement when deriving `Reflect` on nested
generics
# Objective
Fixes#10401
## Solution
* Allow sources to register specific processed/unprocessed watch
warnings.
* Specify per-platform watch warnings. This removes the need to cover
all platform cases in one warning message.
* Only register watch warnings for the _processed_ embedded source, as
warning about watching unprocessed embedded isn't helpful.
---
## Changelog
- Asset sources can now register specific watch warnings.
# Objective
- Shorten paths by removing unnecessary prefixes
## Solution
- Remove the prefixes from many paths which do not need them. Finding
the paths was done automatically using built-in refactoring tools in
Jetbrains RustRover.
# Objective
These type are unavailable to editors and scripting interfaces making
use of reflection.
## Solution
`#[derive(Reflect)]` and call `.register_type` during plugin
initialization.
---
## Changelog
### Added
- Implement `Reflect` for audio-related types, and register them.
# Objective
- Materials should be a more frequent rebind then meshes (due to being
able to use a single vertex buffer, such as in #10164) and therefore
should be in a higher bind group.
---
## Changelog
- For 2d and 3d mesh/material setups (but not UI materials, or other
rendering setups such as gizmos, sprites, or text), mesh data is now in
bind group 1, and material data is now in bind group 2, which is swapped
from how they were before.
## Migration Guide
- Custom 2d and 3d mesh/material shaders should now use bind group 2
`@group(2) @binding(x)` for their bound resources, instead of bind group
1.
- Many internal pieces of rendering code have changed so that mesh data
is now in bind group 1, and material data is now in bind group 2.
Semi-custom rendering setups (that don't use the Material or Material2d
APIs) should adapt to these changes.
# Objective
Keep essentially the same structure of `EntityHasher` from #9903, but
rephrase the multiplication slightly to save an instruction.

## Solution
Today, the hash is
```rust
self.hash = i | (i.wrapping_mul(FRAC_U64MAX_PI) << 32);
```
with `i` being `(generation << 32) | index`.
Expanding things out, we get
```rust
i | ( (i * CONST) << 32 )
= (generation << 32) | index | ((((generation << 32) | index) * CONST) << 32)
= (generation << 32) | index | ((index * CONST) << 32) // because the generation overflowed
= (index * CONST | generation) << 32 | index
```
What if we do the same thing, but with `+` instead of `|`? That's almost
the same thing, except that it has carries, which are actually often
better in a hash function anyway, since it doesn't saturate. (`|` can be
dangerous, since once something becomes `-1` it'll stay that, and
there's no mixing available.)
```rust
(index * CONST + generation) << 32 + index
= (CONST << 32 + 1) * index + generation << 32
= (CONST << 32 + 1) * index + (WHATEVER << 32 + generation) << 32 // because the extra overflows and thus can be anything
= (CONST << 32 + 1) * index + ((CONST * generation) << 32 + generation) << 32 // pick "whatever" to be something convenient
= (CONST << 32 + 1) * index + ((CONST << 32 + 1) * generation) << 32
= (CONST << 32 + 1) * index +((CONST << 32 + 1) * (generation << 32)
= (CONST << 32 + 1) * (index + generation << 32)
= (CONST << 32 + 1) * (generation << 32 | index)
= (CONST << 32 + 1) * i
```
So we can do essentially the same thing using a single multiplication
instead of doing multiply-shift-or.
LLVM was already smart enough to merge the shifting into a
multiplication, but this saves the extra `or`:
<https://rust.godbolt.org/z/MEvbz4eo4>
It's a very small change, and often will disappear in load latency
anyway, but it's a couple percent faster in lookups:
(There was more of an improvement here before #10558, but with `to_bits`
being a single `qword` load now, keeping things mostly as it is turned
out to be better than the bigger changes I'd tried in #10605.)

## Changelog
(Probably skip it)
## Migration Guide
(none needed)
# Objective
the pbr prepass vertex shader currently only sets
`VertexOutput::world_position` when deferred or motion prepasses are
enabled.
the field is always in the vertex output so is otherwise undetermined,
and the calculation is very cheap.
## Solution
always set the world position in the pbr prepass vert shader.
# Objective
`GlobalsUniform` provides the current time to shaders, which is useful
for animations. `UiMaterial` is an abstraction that makes it easier to
write custom shaders for UI elements.
This PR makes it possible to use the `GlobalsUniform` in `UiMaterial`
shaders.
## Solution
The `GlobalsUniform` is bound to `@group(0) @binding(1)`. It is
accessible in shaders with:
```wgsl
#import bevy_render::globals::Globals
@group(0) @binding(1)
var<uniform> globals: Globals;
```
---
## Changelog
Added `GlobalsUniform` in `UiMaterial` shaders
## Discussion
Should I modify the existing ui_material example to showcase this?
# Objective
Related to #10612.
Enable the
[`clippy::manual_let_else`](https://rust-lang.github.io/rust-clippy/master/#manual_let_else)
lint as a warning. The `let else` form seems more idiomatic to me than a
`match`/`if else` that either match a pattern or diverge, and from the
clippy doc, the lint doesn't seem to have any possible false positive.
## Solution
Add the lint as warning in `Cargo.toml`, refactor places where the lint
triggers.
# Objective
Partially addresses #10612
After moving the initial docs_markdown warning, this is a PR that moves
the rest of the CI clippy lint definitions to the cargo.toml.
## Solution
- the `tools/ci/src/main.rs` clippy lints removed and just the warning
flag remains.
- the warnings moved to the root cargo workspace toml.
# Objective
- Follow up to #9694
## Solution
- Same api as #9694 but adapted for `BindGroupLayoutEntry`
- Use the same `ShaderStages` visibilty for all entries by default
- Add `BindingType` helper function that mirror the wgsl equivalent and
that make writing layouts much simpler.
Before:
```rust
let layout = render_device.create_bind_group_layout(&BindGroupLayoutDescriptor {
label: Some("post_process_bind_group_layout"),
entries: &[
BindGroupLayoutEntry {
binding: 0,
visibility: ShaderStages::FRAGMENT,
ty: BindingType::Texture {
sample_type: TextureSampleType::Float { filterable: true },
view_dimension: TextureViewDimension::D2,
multisampled: false,
},
count: None,
},
BindGroupLayoutEntry {
binding: 1,
visibility: ShaderStages::FRAGMENT,
ty: BindingType::Sampler(SamplerBindingType::Filtering),
count: None,
},
BindGroupLayoutEntry {
binding: 2,
visibility: ShaderStages::FRAGMENT,
ty: BindingType::Buffer {
ty: bevy::render::render_resource::BufferBindingType::Uniform,
has_dynamic_offset: false,
min_binding_size: Some(PostProcessSettings::min_size()),
},
count: None,
},
],
});
```
After:
```rust
let layout = render_device.create_bind_group_layout(
"post_process_bind_group_layout"),
&BindGroupLayoutEntries::sequential(
ShaderStages::FRAGMENT,
(
texture_2d_f32(),
sampler(SamplerBindingType::Filtering),
uniform_buffer(false, Some(PostProcessSettings::min_size())),
),
),
);
```
Here's a more extreme example in bevy_solari:

---
## Changelog
- Added `BindGroupLayoutEntries` and all `BindingType` helper functions.
## Migration Guide
`RenderDevice::create_bind_group_layout()` doesn't take a
`BindGroupLayoutDescriptor` anymore. You need to provide the parameters
separately
```rust
// 0.12
let layout = render_device.create_bind_group_layout(&BindGroupLayoutDescriptor {
label: Some("post_process_bind_group_layout"),
entries: &[
BindGroupLayoutEntry {
// ...
},
],
});
// 0.13
let layout = render_device.create_bind_group_layout(
"post_process_bind_group_layout",
&[
BindGroupLayoutEntry {
// ...
},
],
);
```
## TODO
- [x] implement a `Dynamic` variant
- [x] update the `RenderDevice::create_bind_group_layout()` api to match
the one from `RenderDevice::creat_bind_group()`
- [x] docs
# Objective
- Fixes#7680
- This is an updated for https://github.com/bevyengine/bevy/pull/8899
which had the same objective but fell a long way behind the latest
changes
## Solution
The traits `WorldQueryData : WorldQuery` and `WorldQueryFilter :
WorldQuery` have been added and some of the types and functions from
`WorldQuery` has been moved into them.
`ReadOnlyWorldQuery` has been replaced with `ReadOnlyWorldQueryData`.
`WorldQueryFilter` is safe (as long as `WorldQuery` is implemented
safely).
`WorldQueryData` is unsafe - safely implementing it requires that
`Self::ReadOnly` is a readonly version of `Self` (this used to be a
safety requirement of `WorldQuery`)
The type parameters `Q` and `F` of `Query` must now implement
`WorldQueryData` and `WorldQueryFilter` respectively.
This makes it impossible to accidentally use a filter in the data
position or vice versa which was something that could lead to bugs.
~~Compile failure tests have been added to check this.~~
It was previously sometimes useful to use `Option<With<T>>` in the data
position. Use `Has<T>` instead in these cases.
The `WorldQuery` derive macro has been split into separate derive macros
for `WorldQueryData` and `WorldQueryFilter`.
Previously it was possible to derive both `WorldQuery` for a struct that
had a mixture of data and filter items. This would not work correctly in
some cases but could be a useful pattern in others. *This is no longer
possible.*
---
## Notes
- The changes outside of `bevy_ecs` are all changing type parameters to
the new types, updating the macro use, or replacing `Option<With<T>>`
with `Has<T>`.
- All `WorldQueryData` types always returned `true` for `IS_ARCHETYPAL`
so I moved it to `WorldQueryFilter` and
replaced all calls to it with `true`. That should be the only logic
change outside of the macro generation code.
- `Changed<T>` and `Added<T>` were being generated by a macro that I
have expanded. Happy to revert that if desired.
- The two derive macros share some functions for implementing
`WorldQuery` but the tidiest way I could find to implement them was to
give them a ton of arguments and ask clippy to ignore that.
## Changelog
### Changed
- Split `WorldQuery` into `WorldQueryData` and `WorldQueryFilter` which
now have separate derive macros. It is not possible to derive both for
the same type.
- `Query` now requires that the first type argument implements
`WorldQueryData` and the second implements `WorldQueryFilter`
## Migration Guide
- Update derives
```rust
// old
#[derive(WorldQuery)]
#[world_query(mutable, derive(Debug))]
struct CustomQuery {
entity: Entity,
a: &'static mut ComponentA
}
#[derive(WorldQuery)]
struct QueryFilter {
_c: With<ComponentC>
}
// new
#[derive(WorldQueryData)]
#[world_query_data(mutable, derive(Debug))]
struct CustomQuery {
entity: Entity,
a: &'static mut ComponentA,
}
#[derive(WorldQueryFilter)]
struct QueryFilter {
_c: With<ComponentC>
}
```
- Replace `Option<With<T>>` with `Has<T>`
```rust
/// old
fn my_system(query: Query<(Entity, Option<With<ComponentA>>)>)
{
for (entity, has_a_option) in query.iter(){
let has_a:bool = has_a_option.is_some();
//todo!()
}
}
/// new
fn my_system(query: Query<(Entity, Has<ComponentA>)>)
{
for (entity, has_a) in query.iter(){
//todo!()
}
}
```
- Fix queries which had filters in the data position or vice versa.
```rust
// old
fn my_system(query: Query<(Entity, With<ComponentA>)>)
{
for (entity, _) in query.iter(){
//todo!()
}
}
// new
fn my_system(query: Query<Entity, With<ComponentA>>)
{
for entity in query.iter(){
//todo!()
}
}
// old
fn my_system(query: Query<AnyOf<(&ComponentA, With<ComponentB>)>>)
{
for (entity, _) in query.iter(){
//todo!()
}
}
// new
fn my_system(query: Query<Option<&ComponentA>, Or<(With<ComponentA>, With<ComponentB>)>>)
{
for entity in query.iter(){
//todo!()
}
}

# Objective
Kind of helps #10509
## Solution
Add a line to `prepass.wgsl` that ensure the `instance_index` push
constant is always used on WebGL 2. This is not a full fix, as the
_second_ a custom shader is used that doesn't use the push constant, the
breakage will resurface. We have satisfying medium term and long term
solutions. This is just a short term hack for 0.12.1 that will make more
cases work. See #10509 for more details.
# Objective
- `insert_reflect` relies on `reflect_type_path`, which doesn't gives
the actual type path for object created by `clone_value`, leading to an
unexpected panic. This is a workaround for it.
- Fix#10590
## Solution
- Tries to get type path from `get_represented_type_info` if get failed
from `reflect_type_path`.
---
## Defect remaining
- `get_represented_type_info` implies a shortage on performance than
using `TypeRegistry`.
# Objective
Fixes#10688
There were a number of issues at play:
1. The GLTF loader was not registering Scene dependencies properly. They
were being registered at the root instead of on the scene assets. This
made `LoadedWithDependencies` fire immediately on load.
2. Recursive labeled assets _inside_ of labeled assets were not being
loaded. This only became relevant for scenes after fixing (1) because we
now add labeled assets to the nested scene `LoadContext` instead of the
root load context. I'm surprised nobody has hit this yet. I'm glad I
caught it before somebody hit it.
3. Accessing "loaded with dependencies" state on the Asset Server is
boilerplatey + error prone (because you need to manually query two
states).
## Solution
1. In GltfLoader, use a nested LoadContext for scenes and load
dependencies through that context.
2. In the `AssetServer`, load labeled assets recursively.
3. Added a simple `asset_server.is_loaded_with_dependencies(id)`
I also added some docs to `LoadContext` to help prevent this problem in
the future.
---
## Changelog
- Added `AssetServer::is_loaded_with_dependencies`
- Fixed GLTF Scene dependencies
- Fixed nested labeled assets not being loaded

# Objective
- Fixes#10676, preventing a possible memory leak for commands which
owned resources.
## Solution
Implemented `Drop` for `CommandQueue`. This has been done entirely in
the private API of `CommandQueue`, ensuring no breaking changes. Also
added a unit test, `test_command_queue_inner_drop_early`, based on the
reproduction steps as outlined in #10676.
## Notes
I believe this can be applied to `0.12.1` as well, but I am uncertain of
the process to make that kind of change. Please let me know if there's
anything I can do to help with the back-porting of this change.

# Objective
Fixes#10157
## Solution
Add `AssetMetaCheck` resource which can configure when/if asset meta
files will be read:
```rust
app
// Never attempts to look up meta files. The default meta configuration will be used for each asset.
.insert_resource(AssetMetaCheck::Never)
.add_plugins(DefaultPlugins)
```
This serves as a band-aid fix for the issue with wasm's
`HttpWasmAssetReader` creating a bunch of requests for non-existent
meta, which can slow down asset loading (by waiting for the 404
response) and creates a bunch of noise in the logs. This also provides a
band-aid fix for the more serious issue of itch.io deployments returning
403 responses, which results in full failure of asset loads.
If users don't want to include meta files for all deployed assets for
web builds, and they aren't using meta files at all, they should set
this to `AssetMetaCheck::Never`.
If users do want to include meta files for specific assets, they can use
`AssetMetaCheck::Paths`, which will only look up meta for those paths.
Currently, this defaults to `AssetMetaCheck::Always`, which makes this
fully non-breaking for the `0.12.1` release. _**However it _is_ worth
discussing making this `AssetMetaCheck::Never` by default**_, given that
I doubt most people are using meta files without the Asset Processor
enabled. This would be a breaking change, but it would make WASM / Itch
deployments work by default, which is a pretty big win imo. The downside
is that people using meta files _without_ processing would need to
manually enable `AssetMetaCheck::Always`, which is also suboptimal.
When in `AssetMetaCheck::Processed`, the meta check resource is ignored,
as processing requires asset meta files to function.
In general, I don't love adding this knob as things should ideally "just
work" in all cases. But this is the reality of the current situation.
---
## Changelog
- Added `AssetMetaCheck` resource, which can configure when/if asset
meta files will be read
# Objective
- Format `benches` crate to match current Rust standards.
## Solution
- Ran `cargo fmt` in the `benches` crate.
## Notes
I accidentally came across this when working on the `Drop`
implementation for `CommandQueue` and rather embarrassingly let it sneak
into my PR there. I think it makes sense to ensure this crate is also
well formatted to avoid it in the future.
# Objective
Resolves#10743.
## Solution
Copied over the documentation written by @stepancheng from PR #10718.
I left out the lines from the doctest where `<()>` is removed, as that
seemed to be the part people couldn't decide on whether to keep or not.
## Objective
Currently, events are dropped after two frames. This cadence wasn't
*chosen* for a specific reason, double buffering just lets events
persist for at least two frames. Events only need to be dropped at a
predictable point so that the event queues don't grow forever (i.e.
events should never cause a memory leak).
Events (and especially input events) need to be observable by systems in
`FixedUpdate`, but as-is events are dropped before those systems even
get a chance to see them.
## Solution
Instead of unconditionally dropping events in `First`, require
`FixedUpdate` to first queue the buffer swap (if the `TimePlugin` has
been installed). This way, events are only dropped after a frame that
runs `FixedUpdate`.
## Future Work
In the same way we have independent copies of `Time` for tracking time
in `Main` and `FixedUpdate`, we will need independent copies of `Input`
for tracking press/release status correctly in `Main` and `FixedUpdate`.
--
Every run of `FixedUpdate` covers a specific timespan. For example, if
the fixed timestep `Δt` is 10ms, the first three `FixedUpdate` runs
cover `[0ms, 10ms)`, `[10ms, 20ms)`, and `[20ms, 30ms)`.
`FixedUpdate` can run many times in one frame. For truly
framerate-independent behavior, each `FixedUpdate` should only see the
events that occurred in its covered timespan, but what happens right now
is the first step in the frame reads all pending events.
Fixing that will require timestamped events.

The `generate_composite_uuid` utility function hidden in
`bevy_reflect::__macro_exports` could be generally useful to users.
For example, I previously relied on `Hash` to generate a `u64` to create
a deterministic `HandleId`. In v0.12, `HandleId` has been replaced by
`AssetId` which now requires a `Uuid`, which I could generate with this
function.
## Solution
Relocate `generate_composite_uuid` from `bevy_reflect::__macro_exports`
to `bevy_utils::uuid`.
It is still re-exported under `bevy_reflect::__macro_exports` so there
should not be any breaking changes (although, users should generally not
rely on pseudo-private/hidden modules like `__macro_exports`).
I chose to keep it in `bevy_reflect::__macro_exports` so as to not
clutter up our public API and to reduce the number of changes in this
PR. We could have also marked the export as `#[doc(hidden)]`, but
personally I like that we have a dedicated module for this (makes it
clear what is public and what isn't when just looking at the macro
code).

## Changelog
- Moved `generate_composite_uuid` to `bevy_utils::uuid` and made it
public
- Note: it was technically already public, just hidden

The `nondeterministic_system_order` example doesn't actually detect and

It is currently impossible to control the relative ordering of two 2D

I incorrectly assumed that moving a system from `Update` to
`FixedUpdate` would simplify logic without hurting performance.
But this is not the case: if there's single-threaded long computation in
the `FixedUpdate`, the machine won't do anything else in parallel with
it. Which might be not what users expect.
So this PR adds a note. But maybe it is obvious, I don't know.
# Objective
fix webgpu+chrome(119) textureSample in non-uniform control flow error
## Solution
modify view transmission texture sampling to use textureSampleLevel.
there are no mips for the view transmission texture, so this doesn't
change the result, but it removes the need for the samples to be in
uniform control flow.
note: in future we may add a mipchain to the transmission texture to
improve the blur effect. if uniformity analysis hasn't improved, this
would require switching to manual derivative calculations (which is
something we plan to do anyway).

- Move `arc_2d` and `Arc2dBuilder` into `arcs.rs`
- turns out there's no 3d arc function! I'll add one Soon(TM) in another
MR
## Changelog
- Changed
- moved `gizmos::Arc2dBuilder` to `gizmos::arcs::Arc2dBuilder`
## Migration Guide
- `gizmos::Arc2dBuilder` -> `gizmos::arcs::Arc2dBuilder`
# Objective
Problems:
* The clipped, non-visible regions of UI nodes are interactive.
* `RelativeCursorPostion` is set relative to the visible part of the
node. It should be relative to the whole node.
* The `RelativeCursorPostion::mouse_over` method returns `true` when the
mouse is over a clipped part of a node.
fixes#10470
## Solution
Intersect a node's bounding rect with its clipping rect before checking
if it contains the cursor.
Added the field `normalized_visible_node_rect` to
`RelativeCursorPosition`. This is set to the bounds of the unclipped
area of the node rect by `ui_focus_system` expressed in normalized
coordinates relative to the entire node.
Instead of checking if the normalized cursor position lies within a unit
square, it instead checks if it is contained by
`normalized_visible_node_rect`.
Added outlines to the `overflow` example that appear when the cursor is
over the visible part of the images, but not the clipped area.

## Changelog
* `ui_focus_system` intersects a node's bounding rect with its clipping
rect before checking if mouse over.
* Added the field `normalized_visible_node_rect` to
`RelativeCursorPosition`. This is set to the bounds of the unclipped
area of the node rect by `ui_focus_system` expressed in normalized
coordinates relative to the entire node.
* `RelativeCursorPostion` is calculated relative to the whole node's
position and size, not only the visible part.
* `RelativeCursorPosition::mouse_over` only returns true when the mouse
is over an unclipped region of the UI node.
* Removed the `Deref` and `DerefMut` derives from
`RelativeCursorPosition` as it is no longer a single field struct.
* Added some outlines to the `overflow` example that respond to
`Interaction` changes.
## Migration Guide
The clipped areas of UI nodes are no longer interactive.
`RelativeCursorPostion` is now calculated relative to the whole node's
position and size, not only the visible part. Its `mouse_over` method
only returns true when the cursor is over an unclipped part of the node.
`RelativeCursorPosition` no longer implements `Deref` and `DerefMut`.
# Objective
- Fixes#10695
## Solution
Fixed obvious blunder in `PartialEq` implementation for
`UntypedAssetId`'s where the `TypeId` was not included in the
comparison. This was not picked up in the unit tests I added because
they only tested over a single asset type.
# Objective
- I've been experimenting with different patterns to try and make async
tasks more convenient. One of the better ones I've found is to return a
command queue to allow for deferred &mut World access. It can be
convenient to check for task completion in a normal system, but it is
hard to do something with the command queue after getting it back. This
pr adds a `append` to Commands. This allows appending the returned
command queue onto the system's commands.
## Solution
- I edited the async compute example to use the new `append`, but not
sure if I should keep the example changed as this might be too
opinionated.
## Future Work
- It would be very easy to pull the pattern used in the example out into
a plugin or a external crate, so users wouldn't have to add the checking
system.

## Changelog
- add `append` to `Commands` and `CommandQueue`
