# Objective
- Fixes#14059
- `morphed_skinned_mesh_layout` is the same as
`morphed_skinned_motion_mesh_layout` but shouldn't have the skin / morph
from previous frame, as they're used for motion
## Solution
- Remove the extra entries
## Testing
- Run with the glTF file reproducing #14059, it works
# Objective
- Fixes a correctness error introduced in
https://github.com/bevyengine/bevy/pull/14013 ...
## Solution
I've been playing around a lot of with the access code and I realized
that I introduced a soundness error when trying to simplify the code.
When we have a `Or<(With<A>, With<B>)>` filter, we cannot call
```
let mut intermediate = FilteredAccess::default();
$name::update_component_access($name, &mut intermediate);
_new_access.append_or(&intermediate);
```
because that's just equivalent to adding the new components as `Or`
clauses.
For example if the existing `filter_sets` was `vec![With<C>]`, we would
then get `vec![With<C>, With<A>, With<B>]` which translates to `A or B
or C`.
Instead what we want is `(A and B) or (A and C)`, so we need to have
each new OR clause compose with the existing access like so:
```
let mut intermediate = _access.clone();
// if we previously had a With<C> in the filter_set, this will become `With<C> AND With<A>`
$name::update_component_access($name, &mut intermediate);
_new_access.append_or(&intermediate);
```
## Testing
- Added a unit test that is broken in main, but passes in this PR
# Objective
`sickle_ui` needs `PartialEq` on components to turn them into animatable
style attributes.
## Solution
All properties of Outline is already `PartialEq`, add derive on
`Outline` as well.
## Testing
- used `sickle_ui` to test if it can be made animatable
As reported in #14004, many third-party plugins, such as Hanabi, enqueue
entities that don't have meshes into render phases. However, the
introduction of indirect mode added a dependency on mesh-specific data,
breaking this workflow. This is because GPU preprocessing requires that
the render phases manage indirect draw parameters, which don't apply to
objects that aren't meshes. The existing code skips over binned entities
that don't have indirect draw parameters, which causes the rendering to
be skipped for such objects.
To support this workflow, this commit adds a new field,
`non_mesh_items`, to `BinnedRenderPhase`. This field contains a simple
list of (bin key, entity) pairs. After drawing batchable and unbatchable
objects, the non-mesh items are drawn one after another. Bevy itself
doesn't enqueue any items into this list; it exists solely for the
application and/or plugins to use.
Additionally, this commit switches the asset ID in the standard bin keys
to be an untyped asset ID rather than that of a mesh. This allows more
flexibility, allowing bins to be keyed off any type of asset.
This patch adds a new example, `custom_phase_item`, which simultaneously
serves to demonstrate how to use this new feature and to act as a
regression test so this doesn't break again.
Fixes#14004.
## Changelog
### Added
* `BinnedRenderPhase` now contains a `non_mesh_items` field for plugins
to add custom items to.
# Objective
`StaticSystemParam` should delegate all `SystemParam` methods to the
inner param, but it looks like it was missed when the new `queue()`
method was added in #10839.
## Solution
Implement `StaticSystemParam::queue()` to delegate to the inner param.
The comment was incorrect - we are already looking at the pyramid
texture so we do not need to transform the size in any way. Doing that
resulted in a mip that was too fine to be selected in certain cases,
which resulted in a 2x2 pixel footprint not actually fully covering the
cluster sphere - sometimes this could lead to a non-conservative depth
value being computed which resulted in the cluster being marked as
invisible incorrectly.
This change updates meshopt-rs to 0.3 to take advantage of the newly
added sparse simplification mode: by default, simplifier assumes that
the entire mesh is simplified and runs a set of calculations that are
O(vertex count), but in our case we simplify many small mesh subsets
which is inefficient.
Sparse mode instead assumes that the simplified subset is only using a
portion of the vertex buffer, and optimizes accordingly. This changes
the meaning of the error (as it becomes relative to the subset, in our
case a meshlet group); to ensure consistent error selection, we also use
the ErrorAbsolute mode which allows us to operate in mesh coordinate
space.
Additionally, meshopt 0.3 runs optimizeMeshlet automatically as part of
`build_meshlets` so we no longer need to call it ourselves.
This reduces the time to build meshlet representation for Stanford Bunny
mesh from ~1.65s to ~0.45s (3.7x) in optimized builds.
This is a followup to https://github.com/bevyengine/bevy/pull/13904
based on the discussion there, and switches two HashMaps that used
meshlet ids as keys to Vec.
In addition to a small further performance boost for `from_mesh` (1.66s
=> 1.60s), this makes processing deterministic modulo threading issues
wrt CRT rand described in the linked PR. This is valuable for debugging,
as you can visually or programmatically inspect the meshlet distribution
before/after making changes that should not change the output, whereas
previously every asset rebuild would change the meshlet structure.
Tested with https://github.com/bevyengine/bevy/pull/13431; after this
change, the visual output of meshlets is consistent between asset
rebuilds, and the MD5 of the output GLB file does not change either,
which was not the case before.
This change reworks `find_connected_meshlets` to scale more linearly
with the mesh size, which significantly reduces the cost of building
meshlet representations. As a small extra complexity reduction, it moves
`simplify_scale` call out of the loop so that it's called once (it only
depends on the vertex data => is safe to cache).
The new implementation of connectivity analysis builds edge=>meshlet
list data structure, which allows us to only iterate through
`tuple_combinations` of a (usually) small list. There is still some
redundancy as if two meshlets share two edges, they will be represented
in the meshlet lists twice, but it's overall much faster.
Since the hash traversal is non-deterministic, to keep this part of the
algorithm deterministic for reproducible results we sort the output
adjacency lists.
Overall this reduces the time to process bunny mesh from ~4.2s to ~1.7s
when using release; in unoptimized builds the delta is even more
significant.
This was tested by using https://github.com/bevyengine/bevy/pull/13431
and:
a) comparing the result of `find_connected_meshlets` using old and new
code; they are equal in all steps of the clustering process
b) comparing the rendered result of the old code vs new code *after*
making the rest of the algorithm deterministic: right now the loop that
iterates through the result of `group_meshlets()` call executes in
different order between program runs. This is orthogonal to this change
and can be fixed separately.
Note: a future change can shrink the processing time further from ~1.7s
to ~0.4s with a small diff but that requires an update to meshopt crate
which is pending in https://github.com/gwihlidal/meshopt-rs/pull/42.
This change is independent.
When using combinators such as `EntityCommand::with_entity` to build
commands, it can be easy to forget to apply that command, leading to
dead code. In many cases this doesn't even lead to an unused variable
warning, which can make these mistakes difficult to track down

# Objective
Numerous people have been confused that Bevy runs slowly, when the
reason is that the `llvmpipe` software rendered is being used.
## Solution
Printing a warning could reduce the confusion.
# Objective
- Fixes#13728
## Solution
- add a new feature `smaa_luts`. if enables, it also enables `ktx2` and
`zstd`. if not, it doesn't load the files but use placeholders instead
- adds all the resources needed in the same places that system that uses
them are added.
# Objective
Fixes https://github.com/bevyengine/bevy/issues/13993
PR inspired by https://github.com/bevyengine/bevy/pull/14007 to
accomplish the same thing, but maybe in a clearer fashion.
@Gingeh feel free to take my changes and add them to your PR, I don't
want to steal any credit

# Objective
In Bevy 0.13, `BackgroundColor` simply tinted the image of any
`UiImage`. This was confusing: in every other case (e.g. Text), this
added a solid square behind the element. #11165 changed this, but
removed `BackgroundColor` from `ImageBundle` to avoid confusion, since
the semantic meaning had changed.
However, this resulted in a serious UX downgrade / inconsistency, as
this behavior was no longer part of the bundle (unlike for `TextBundle`
or `NodeBundle`), leaving users with a relatively frustrating upgrade
path.
Additionally, adding both `BackgroundColor` and `UiImage` resulted in a
bizarre effect, where the background color was seemingly ignored as it
was covered by a solid white placeholder image.
Fixes#13969.
## Solution
Per @viridia's design:
> - if you don't specify a background color, it's transparent.
> - if you don't specify an image color, it's white (because it's a
multiplier).
> - if you don't specify an image, no image is drawn.
> - if you specify both a background color and an image color, they are
independent.
> - the background color is drawn behind the image (in whatever pixels
are transparent)
As laid out by @benfrankel, this involves:
1. Changing the default `UiImage` to use a transparent texture but a
pure white tint.
2. Adding `UiImage::solid_color` to quickly set placeholder images.
3. Changing the default `BorderColor` and `BackgroundColor` to
transparent.
4. Removing the default overrides for these values in the other assorted
UI bundles.
5. Adding `BackgroundColor` back to `ImageBundle` and `ButtonBundle`.
6. Adding a 1x1 `Image::transparent`, which can be accessed from
`Assets<Image>` via the `TRANSPARENT_IMAGE_HANDLE` constant.
Huge thanks to everyone who helped out with the design in the linked
issue and [the Discord
thread](https://discord.com/channels/691052431525675048/1255209923890118697/1255209999278280844):
this was very much a joint design.
@cart helped me figure out how to set the UiImage's default texture to a
transparent 1x1 image, which is a much nicer fix.
## Testing
I've checked the examples modified by this PR, and the `ui` example as
well just to be sure.
## Migration Guide
- `BackgroundColor` no longer tints the color of images in `ImageBundle`
or `ButtonBundle`. Set `UiImage::color` to tint images instead.
- The default texture for `UiImage` is now a transparent white square.
Use `UiImage::solid_color` to quickly draw debug images.
- The default value for `BackgroundColor` and `BorderColor` is now
transparent. Set the color to white manually to return to previous
behavior.
# Objective
- Fixes#13811 (probably, I lost my test code...)
## Solution
- Turns out that Queue and PrepareAssets are _not_ ordered. We should
probably either rethink our system sets (again), or improve the
documentation here. For reference, I've included the current ordering
below.
- The `prepare_meshlet_meshes_X` systems need to run after
`prepare_assets::<PreparedMaterial<M>>`, and have also been moved to
QueueMeshes.
```rust
schedule.configure_sets(
(
ExtractCommands,
ManageViews,
Queue,
PhaseSort,
Prepare,
Render,
Cleanup,
)
.chain(),
);
schedule.configure_sets((ExtractCommands, PrepareAssets, Prepare).chain());
schedule.configure_sets(QueueMeshes.in_set(Queue).after(prepare_assets::<GpuMesh>));
schedule.configure_sets(
(PrepareResources, PrepareResourcesFlush, PrepareBindGroups)
.chain()
.in_set(Prepare),
);
```
## Testing
- Ambiguity checker to make sure I don't have ambiguous system ordering
accurate for debugging. To ensure that its can still be readily logged
in error messages and inspectors, this PR added a more concise and
human-friendly `Display` impl.
However, users found this form too verbose: the `to_bits` information
was unhelpful and too long. Fixes#13980.
- Don't include `Entity::to_bits` in the `Display` implementation for
`Entity`. This information can readily be accessed and logged for users
who need it.
- Also clean up the implementation of `Display` for `DebugName`,
introduced in https://github.com/bevyengine/bevy/pull/13760, to simply
use the new `Display` impl (since this was the desired format there).
I've updated an existing test to verify the output of `Entity::display`.

# Objective
- Fixes https://github.com/bevyengine/bevy/issues/14003
## Solution
- Expose an API to perform updates for a specific sub-app, so we can
avoid mutable borrow the app twice.
## Testing
- I have tested the API by modifying the code in the `many_lights`
example with the following changes:
```rust
impl Plugin for LogVisibleLights {
fn build(&self, app: &mut App) {
let Some(render_app) = app.get_sub_app_mut(RenderApp) else {
return;
};
render_app.add_systems(Render, print_visible_light_count.in_set(RenderSet::Prepare));
}
fn finish(&self, app: &mut App) {
app.update_sub_app_by_label(RenderApp);
}
}
```
---
## Changelog
- add the `update_sub_app_by_label` API to `App` and `SubApps`.

# Objective
Tight, in-frame generation, re-parenting, despawning, etc., UI
operations could sometime lead taffy to panic (invalid SlotMap key used)
when an entity with an invalid state later despawned.
Fixes#12403
## Solution
Move the `remove_entities` call after children updates.
## Testing
`sickle_ui` had a case that always caused the panic. Tested before this
change, after this change, and before the change again to make sure the
error is there without the fix. The fix worked. Test steps and used
commit described in issue #12403.
I have also ran every bevy UI example, though none of them deal with
entity re-parenting or removal. No regression detected on them.
Tested on Windows only.
* Fixes https://github.com/bevyengine/bevy/issues/13813
* Fixes https://github.com/bevyengine/bevy/issues/13810
Tested a combined scene with both regular meshes and meshlet meshes
with:
* Regular forward setup
* Forward + normal/motion vector prepasses
* Deferred (with depth prepass since that's required)
* Deferred + depth/normal/motion vector prepasses
Still broken:
* Using meshlet meshes rendering in deferred and regular meshes
rendering in forward + depth/normal prepass. I don't know how to fix
this at the moment, so for now I've just add instructions to not mix
them.
# Objective
`with_event` will result in unsafe casting of event data of the given
type to the type expected by the Observer system. This is inherently
unsafe.
## Solution
Flag `Observer::with_event` and `ObserverDescriptor::with_events` as
unsafe. This will not affect normal workflows as `with_event` is
intended for very specific (largely internal) use cases.
This _should_ be backported to 0.14 before release.
---
## Changelog
- `Observer::with_event` is now unsafe.
- Rename `ObserverDescriptor::with_triggers` to
`ObserverDescriptor::with_events` and make it unsafe.
# Objective
- Fixes#13702
- When creating a new window, its scale was changed to match the one
returned by winit, but its size was not which resulted in an incorrect
size until the event with the correct size was received, at least 1
frame later
## Solution
- Apply the window scale to its size when creating it
Fixes#13701
After `winit` upgrade to `0.31`, windows were no longer correctly
resizing. This appears to just have been a simple mistake, where the new
physical size was being sourced from the `winit` window rather than on
the incoming `Window` component.
## Testing
Tested on macOS, but I'm curious whether this was also broken on other
platforms.
# Objective
Fixes#13920
## Solution
As described in the issue.
## Testing
Moved a custom transition plugin in example before any of the app-state
methods.
# Objective
Fix a 9-slice asymmetric border issue that
[QueenOfSquiggles](https://blobfox.coffee/@queenofsquiggles/112639035165575222)
found. Here's the behavior before:

Here's the behavior with the fix.
<img width="327" alt="the-fix"
src="https://github.com/bevyengine/bevy/assets/54390/33a4e3f0-b6a8-448e-9654-1197218ea11d">
## Testing
I used QueenOfSquiggles
[repo](https://github.com/QueenOfSquiggles/my-bevy-learning-project) to
exercise the code. I manually went through a number of variations of the
border and caught a few other issues after the first pass. I added some
code to create random borders and though they often looked funny there
weren't any gaps like before.
### Unit Tests
I did add some tests to `slicer.rs` mostly as an exploratory programming
exercise. So they currently act as a limited, incomplete,
"golden-file"-ish approach. Perhaps they're not worth keeping.
In order to write the tests, I did add a `PartialEq` derive for
`TextureSlice`.
I only tested these changes on macOS.
---
## Changelog
Make 9-slice textures work with asymmetric borders.
# Objective
Fixes#13299
On Linux/X11, changing focus into a winit window will produce winit
KeyboardInput events with a "is_synthetic=true" flag that are not
intended to be used. Bevy erroneously passes them on to the user,
resulting in phantom key presses.
## Solution
This patch properly filters out winit KeyboardInput events with
"is_synthetic=true".
For example, pressing Alt+Tab to focus a bevy winit window results in a
permanently stuck Tab key until the user presses Tab once again to
produce a winit KeyboardInput release event. The Tab key press event
that causes this problem is "synthetic", should not be used according to
the winit devs, and simply ignoring it fixes this problem.
Synthetic key **releases** are still evaluated though, as they are
essential for correct release key handling. For example, if the user
binds the key combination Alt+1 to the action "move the window to
workspace 1", places the bevy game in workspace 2, focuses the game and
presses Alt+1, then the key release event for the "1" key will be
synthetic. If we would filter out all synthetic keys, the bevy game
would think that the 1 key remains pressed forever, until the user
manually presses+releases the key again inside bevy.
Reference:
https://docs.rs/winit/0.30.0/winit/event/enum.WindowEvent.html#variant.KeyboardInput.field.is_synthetic
Relevant discussion: https://github.com/rust-windowing/winit/issues/3543
## Testing
Tested with the "keyboard_input_events" example. Entering/exiting the
window with various keys, as well as changing its workspace, produces
the correct press/release events.
# Objective
- Fixes#13874
## Solution
- Confirm that the `StatesPlugin` is installed when trying to add
states.
- Skipped for state scoped entities, since those will warn about missing
states.
# Objective
Fixes#13854
## Solution
Removed the inaccurate warning. This was done for a few reasons:
- States not existing is now a valid "state" (for lack of a better term)
- Other run conditions don't provide an equivalent warning
# Objective
- #13846 introduced a bug where text not bound was not displayed
## Solution
- bounds are infinite
- use computed size instead, that already should be using the available
bounds
# Objective
- Fixes#13825
## Solution
- Cherry picked and fixed non-trivial conflicts to be able to merge
#10839 into the 0.14 release branch.

# Objective
- Fixes#13844
- Warn user when initializing state multiple times
## Solution
- `insert_state` will overwrite previously initialized state value,
reset transition events and re-insert it's own transition event.
- `init_state`, `add_sub_state`, `add_computed_state` are idempotent, so
calling them multiple times will emit a warning.
## Testing
- 2 tests confirming overwrite works.
- Given the example from #13844
```rs
use bevy::prelude::*;
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.insert_state(AppState::A)
.insert_state(AppState::B)
.add_systems(OnEnter(AppState::A), setup_a)
.add_systems(OnEnter(AppState::B), setup_b)
.add_systems(OnExit(AppState::A), cleanup_a)
.add_systems(OnExit(AppState::B), cleanup_b)
.run();
}
#[derive(States, Debug, Clone, PartialEq, Eq, Hash)]
enum AppState {

}
fn setup_a() {

}
fn setup_b() {
info!("setting up B");
}
fn cleanup_a() {
info!("cleaning up A");
}
fn cleanup_b() {
info!("cleaning up B");
}
```
We get the following result:
```
INFO states: setting up B
```
which matches our expectations.

when a parent container is auto-sized, text alignments `Center` and

## Solution
ab_glyph positions return +/- values from an anchor point. we currently
transform them to positive values from the min-x of the glyphs, and then
offset from the left of the bounds. instead, we can keep the negative
values as ab_glyph intended and offset from the left/middle/right of the

# Objective
Update to wgpu 0.20
## Solution
Update to wgpu 0.20 and naga_oil 0.14.
## Testing
Tested a few different examples on linux (vulkan, webgl2, webgpu) and

## Changelog
- Updated to wgpu 0.20. Note that we don't currently support wgpu's new
pipeline overridable constants, as they don't work on web currently and
need some more changes to naga_oil (and are somewhat redundant with
naga_oil's shader defs). See wgpu's changelog for more

# Objective
- Fixes#13807
## Solution
- Before this pr we antialiased between 0.5 and -0.5. This pr changes
things to antialias between 0.25 and -0.25. I tried slightly larger
ranges, but the edge between the boxes still showed. I'm not 100% sure
this is the correct solution, but from what I could find the range you
use is more art than science.
## Testing
- Ran rounded_borders example, the code in the linked issue, and the
testing example from #12702.

## Changelog
- reduce antialiasing in ui shader.
StatesPlugin and GizmoPlugin were missing from the doc comment of
DefaultPlugins. I am not sure whether this was for a reason, but i just
stumbled over it and it seemed off...

adapt it to the 0.14 release branch.
---------
As discovered in
https://github.com/Leafwing-Studios/leafwing-input-manager/issues/538,
there appears to be some real weirdness going on in how event updates
are processed between Bevy 0.13 and Bevy 0.14.
To identify the cause and prevent regression, I've added tests to
validate the intended behavior.
My initial suspicion was that this would be fixed by
https://github.com/bevyengine/bevy/pull/13762, but that doesn't seem to
be the case.
Instead, events appear to never be updated at all when using `bevy_app`
by itself. This is part of the problem resolved by
https://github.com/bevyengine/bevy/pull/11528, and introduced by
https://github.com/bevyengine/bevy/pull/10077.
After some investigation, it appears that `signal_event_update_system`
is never added using a bare-bones `App`, and so event updates are always
skipped.
This can be worked around by adding your own copy to a
later-in-the-frame schedule, but that's not a very good fix.
Ensure that if we're not using a `FixedUpdate` schedule, events are
always updated every frame.
To do this, I've modified the logic of `event_update_condition` and
`event_update_system` to clearly and correctly differentiate between the
two cases: where we're waiting for a "you should update now" signal and
where we simply don't care.
To encode this, I've added the `ShouldUpdateEvents` enum, replacing a
simple `bool` in `EventRegistry`'s `needs_update` field.
Now, both tests pass as expected, without having to manually add a
system!
I've written two parallel unit tests to cover the intended behavior:
1. Test that `iter_current_update_events` works as expected in
`bevy_ecs`.
2. Test that `iter_current_update_events` works as expected in
`bevy_app`
I've also added a test to verify that event updating works correctly in
the presence of a fixed main schedule, and a second test to verify that
fixed updating works at all to help future authors narrow down failures.
- [x] figure out why the `bevy_app` version of this test fails but the
`bevy_ecs` version does not
- [x] figure out why `EventRegistry::run_updates` isn't working properly
- [x] figure out why `EventRegistry::run_updates` is never getting
called
- [x] figure out why `event_update_condition` is always returning false
- [x] figure out why `EventRegistry::needs_update` is always false
- [x] verify that the problem is a missing `signal_events_update_system`

…izer (#13442)"
This reverts commit 5cfb063d4a.
- This PR broke bevy-trait-query, which needs to be able to write a
resource in init_state. See #13798 for more details.
- Note this doesn't fix everything as transmutes for bevy-trait-query
will still be broken,. But the current usage in that crate is UB, so we
need to find another solution.
# Objective
Closes#13738
## Solution
Added `from_color` to materials that would support it. Didn't add
`from_color` to `WireframeMaterial` as it doesn't seem we expect users
to be constructing them themselves.
## Testing
None
---
## Changelog
### Added
- `from_color` to `StandardMaterial` so you can construct this material
from any color type.
- `from_color` to `ColorMaterial` so you can construct this material
from any color type.
# Objective
- Mikktspace requires that we normalize world normals/tangents _before_
interpolation across vertices, and then do _not_ normalize after. I had
it backwards.
- We do not (am not supposed to?) need a second set of barycentrics for
motion vectors. If you think about the typical raster pipeline, in the
vertex shader we calculate previous_world_position, and then it gets
interpolated using the current triangle's barycentrics.
## Solution
- Fix normal/tangent processing
- Reuse barycentrics for motion vector calculations
- Not implementing this for 0.14, but long term I aim to remove explicit
vertex tangents and calculate them in the shader on the fly.
## Testing
- I tested out some of the normal maps we have in repo. Didn't seem to
make a difference, but mikktspace is all about correctness across
various baking tools. I probably just didn't have any of the ones that
would cause it to break.
- Didn't test motion vectors as there's a known bug with the depth
buffer and meshlets that I'm waiting on the render graph rewrite to fix.
Reading system information severely slows down the update loop.
Fixes#12848.
Read system info in a separate thread.
- Open the scene 3d example
- Add `FrameTimeDiagnosticsPlugin`, `SystemInformationDiagnosticsPlugin`
and `LogDiagnosticsPlugin` to the app.
- Add this system to the update schedule to disable Vsync on the main
window
```rust
fn change_window_mode(mut windows: Query<&mut Window, Added<Window>>) {
for mut window in &mut windows {
window.present_mode = PresentMode::AutoNoVsync;
}
}
```
- Read the fps values in the console before and after this PR.
On my PC I went from around 50 fps to around 1150 fps.
---
- The `SystemInformationDiagnosticsPlugin` now reads system data
separate of the update cycle.
- The `EXPECTED_SYSTEM_INFORMATION_INTERVAL` constant which defines how
often we read system diagnostic data.

Fixes#13758.
# Objective
Calling `update` on the main app already calls `clear_trackers`. Calling
it again in `SubApps::update` caused RemovedCompenet Events to be
cleared earlier than they should be.
## Solution
- Don't call clear_trackers an extra time.
## Testing
I manually tested the fix with this unit test:
```
#[cfg(test)]
mod test {
use crate::core::{FrameCount, FrameCountPlugin};
use crate::prelude::*;
#[test]
fn test_next_frame_removal() {
#[derive(Component)]
struct Foo;
#[derive(Resource)]
struct RemovedCount(usize);
let mut app = App::new();
app.add_plugins(FrameCountPlugin);
app.add_systems(Startup, |mut commands: Commands| {
for _ in 0..100 {
commands.spawn(Foo);
}
commands.insert_resource(RemovedCount(0));
});
app.add_systems(First, |counter: Res<FrameCount>| {
println!("Frame {}:", counter.0)
});
fn detector_system(
mut removals: RemovedComponents<Foo>,
foos: Query<Entity, With<Foo>>,
mut removed_c: ResMut<RemovedCount>,
) {
for e in removals.read() {
println!(" Detected removed Foo component for {e:?}");
removed_c.0 += 1;
}
let c = foos.iter().count();
println!(" Total Foos: {}", c);
assert_eq!(c + removed_c.0, 100);
}
fn deleter_system(foos: Query<Entity, With<Foo>>, mut commands: Commands) {
foos.iter().next().map(|e| {
commands.entity(e).remove::<Foo>();
});
}
app.add_systems(Update, (detector_system, deleter_system).chain());
app.update();
app.update();
app.update();
app.update();
}
}
```
# Objective
There were some issues with the `serialize` feature:
- `bevy_app` had a `serialize` feature and a dependency on `serde` even
there is no usage of serde at all inside `bevy_app`
- the `bevy_app/serialize` feature enabled `bevy_ecs/serde`, which is
strange
- `bevy_internal/serialize` did not enable `bevy_app/serialize` so there
was no way of serializing an Entity in bevy 0.14
## Solution
- Remove `serde` and `bevy_app/serialize`
- Add a `serialize` flag on `bevy_ecs` that enables `serde`
- ` bevy_internal/serialize` now enables `bevy_ecs/serialize`
# Objective
- If the fog is disabled it still generates a useless branch which can
hurt performance
## Solution
- Make the flag a shader_def instead
## Testing
- I tested enabling/disabling fog works as expected per-material in the
fog example
- I also tested that scenes that don't add the FogSettings resource
still work correctly
## Review notes
I'm not sure how to handle the removed material flag. Right now I just
commented it out and added a not to reuse it instead of creating a new
one.
The documentation for the `State` resource still referenced the use of
`apply_state_transition` to manually force a state transition to occur,
and the question around how to force transitions had come up a few times
on discord.
This is a docs-only change, that does the following:
- Properly references `StateTransition` in the `MainSchedule` docs
- replace the explanations for applying `NextState` with ones that
explain the `StateTransition` schedule, and mentions the possibility of
calling it manually
- Add an example of calling `StateTransition` manually in the docs for
the state transition schedule itself.

# Objective
The error printed-out due to a missing shader file was confusing; This
PR changes the error message.
Fixes#13644
## Solution
I replaced the confusing wording (`... shader is not loaded yet`) with a
clear explanation (`... shader could not be loaded`)
## Testing
> Did you test these changes? If so, how?
removing `assets/shaders/game_of_life.wgsl` & running its associated
example now produces the following error:
```
thread '<unnamed>' panicked at examples/shader/compute_shader_game_of_life.rs:233:25:
Initializing assets/shaders/game_of_life.wgsl:
Pipeline could not be compiled because the following shader could not be loaded: AssetId<bevy_render::render_resource::shader::Shader>{ index: 0, generation: 0}
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Encountered a panic in system `bevy_render::renderer::render_system`!
```
I don't think there are any tests expecting the previous error message,
so this change should not break anything.
> Are there any parts that need more testing?
If there was an intent behind the original message, this might need more
attention.
> How can other people (reviewers) test your changes? Is there anything
specific they need to know?
One should be able to preview the changes by running any example after
deleting/renaming their associated shader(s).
> If relevant, what platforms did you test these changes on, and are
there any important ones you can't test?
N/A
# Objective
Fixes#13711
## Solution
Introduce smaller, generic system sets for each schedule variant, which
are ordered against other generic variants:
- `ExitSchedules<S>` - For `OnExit` schedules, runs from leaf states to
root states.
- `TransitionSchedules<S>` - For `OnTransition` schedules, runs in
arbitrary order.
- `EnterSchedules<S>` - For `OnEnter` schedules, runs from root states
to leaf states.
Also unified `ApplyStateTransition<S>` schedule which works in basically
the same way, just for internals.
## Testing
- One test that tests schedule execution order

# Objective
One thing missing from the new Color implementation in 0.14 is the
ability to easily convert to a u8 representation of the rgb color.
(note this is a redo of PR https://github.com/bevyengine/bevy/pull/13739
as I needed to move the source branch
## Solution
I have added to_u8_array and to_u8_array_no_alpha to a new trait called
ColorToPacked to mirror the f32 conversions in ColorToComponents and
implemented the new trait for Srgba and LinearRgba.
To go with those I also added matching from_u8... functions and
converted a couple of cases that used ad-hoc implementations of that
conversion to use these.
After discussion on Discord of the experience of using the API I renamed
Color::linear to Color::to_linear, as without that it looks like a
constructor (like Color::rgb).
I also added to_srgba which is the other commonly converted to type of
color (for UI and 2D) to match to_linear.
Removed a redundant extra implementation of to_f32_array for LinearColor
as it is also supplied in ColorToComponents (I'm surprised that's
allowed?)
## Testing
Ran all tests and manually tested.
Added to_and_from_u8 to linear_rgba::tests
## Changelog
visible change is Color::linear becomes Color::to_linear.

# Objective
The method `AssetServer::add_async` (added in
https://github.com/bevyengine/bevy/pull/13700) requires a future that
returns an `AssetLoadError` error, which was a bit of an oversight on my
part, as that type of error only really makes sense in the context of
bevy's own asset loader -- returning it from user-defined futures isn't
very useful.
## Solution
Allow passing custom error types to `add_async`, which get cast into a
trait object matching the form of `AssetLoader::load`. If merged before
the next release this will not be a breaking change
# Objective
- Add support for `segments` for extrusion-meshes, akin to what is
possible with cylinders
## Solution
- Added a `.segments(segments: usize)` function to `ExtrusionBuilder`.
- Implemented support for segments in the meshing algorithm.
- If you set `.segments(0)`, the meshing will fail, just like it does
with cylinders.
## Additional information
Here is a wireframe of some extrusions with 1, 2, 3, etc. segments:

# Objective
- Let `init_non_send_resource` take `FromWorld` values again, not only
`Default`
- This reverts an unintended breaking change introduced in #9202
## Solution
- The resource initialized with `init_non_send_resource` requires
`FromWorld` again
# Objective
The `EntityCommands::despawn` method was previously changed from
panicking behavior to a warning, but the docs continue to state that it
panics.
## Solution
- Removed panic section, copied warning blurb from `World::despawn`
- Adds a similar warning blurb to
`DespawnRecursiveExt::despawn_recursive` and
`DespawnRecursiveExt::despawn_descendants`
# Objective
- In #13649 additional method had been added to AppExitStates, but there
feature gate left for method in implementation for App at refactoring
stage.
- Fixes#13733 .
## Solution
- Removed the feature gate.
## Testing
- Ran reproducing example from #13733 with no compilation errors
# Objective
Some use cases might require holding onto the previous state of the
animation player for change detection.
## Solution
Added `clone` and `copy` implementation to most animation types.
Added optimized `clone_from` implementations for the specific use case
of holding a `PreviousAnimationPlayer` component.

Changes:
- Track whether an output texture has been written to yet and only clear
it on the first write.
- Use `ClearColorConfig` on `CameraOutputMode` instead of a raw
`LoadOp`.
- Track whether a output texture has been seen when specializing the
upscaling pipeline and use alpha blending for extra cameras rendering to
that texture that do not specify an explicit blend mode.
Fixes#6754
## Testing
Tested against provided test case in issue:
---
## Changelog
- Allow cameras rendering to the same output texture with mixed hdr to
work correctly.
## Migration Guide
- - Change `CameraOutputMode` to use `ClearColorConfig` instead of
`LoadOp`.
# Objective
All the links that should go to the `Transform` type in the `Transform`
and `GlobalTransform` docs currently go to the `transform` example
instead.
## Solution
Fix collision of link labels in `Transform` and `GlobalTransform` docs.
A naked unwrap led to an opaque error that can be hit when using the
embedded filewatcher.
I've changed this an unwrap_or_else panic! with the error message
providing more details about the failed operation.
A better solution would be to print an error! and not panic...
This was tested with the asset_processing example.

# Objective
- apply_normal_mapping was changed to use TBN but the pbr_prepass was
not updated for that change
## Solution
- Update the pbr_prepass to correctly apply normal mapping
* Rename cull_meshlets -> cull_clusters
* Rename meshlet_visible -> cluster_visible
* Add an if statement around meshlet_second_pass_candidates writes,
maybe a small bit of performance.

`Mesh::merge` does not need ownership of the right hand side mesh.
## Solution
Made `Mesh::merge` take a reference.
## Testing
Modified existing tests.

## Changelog
Made `Mesh::merge` take a reference.
## Migration Guide
* `Mesh::merge` now take a reference of a mesh instead of an owned mesh.
# Objective
Currently, bevy supports custom asset loading via `AssetServer:;add`,
which allows you to add arbitrary assets to the asset system and returns
a handle to it. However this only works for assets that have already
been fully loaded. If your loading logic involves any async, you need to
wait until the asset is done loading before adding it to the server.
This is problematic, as the `Handle` does not get allocated until the
very end, which makes it very difficult to use and defeats the value of
having handles for asynchronously-loaded assets.
## Solution
Add the method `AssetServer::add_async`. This has the same behavior as
`AssetServer::add`, only it accepts a future instead of a fully loaded
asset.
## Testing
I added an identical method to my company's fork of bevy, which works in
our app. I'm not quite sure how to go about adding an actual unit test
for asset loading behvior, but I will note that `AssetServer::add` also
does not appear to have any tests.
---
## Changelog
+ Added `AssetServer::add_async`, which allows adding assets with custom
asynchronous loading behavior to the `AssetServer`
# Objective
- Fixes#13687
## Solution
- Text rendering in UI is still dependent on the `PrimaryWIndow`
- implements #10559 for text rendering
There are other parts of UI that are still `PrimaryWindow` dependent, if
the changes here are OK I'll apply them everywhere.
I'm not a fan of the `EntityHashMap` here to hold the scale factors, but
it seems the quick and easy fix
## Testing
- Run example `multiple_windows` on a screen with a scale factor
different than 1, close the primary window
# Objective
Add labels to GltfNode and GltfMesh - they are missing from the assets
even though they are need if one wants to write a custom Gltf spawning
logic.
Eg AnimationPlayer relies on Name component of the node entities to
control the animation. There is no way to actually get names of the gltf
nodes, thus you can't manually spawn subtree from the scene and animate
it.
## Solution
- Add label field and make use of existing label creation logic to store
it there.
## Testing
- Ran all tests
- Fixed tests for node_hierarchy to use lable now

# Objective
- Fixes#10820.
## Solution
- Check that the asset ID to be inserted is still being managed.
- Since this route is only used by `AssetServer`-tracked handles, if the
`infos` map no longer contains the asset ID, all handles must have been
dropped. In this case, since nobody can be watching for the result,
we're safe to bail out. This avoids the panic when inserting the asset,
because when the handles are dropped, its slot in `Assets<A>` is
poisoned.
- Someone may be waiting for a labelled asset rather than the main
asset, these are handled with separate calls to `process_asset_load`, so
shouldn't cause any issues.
- Removed the workaround keeping asset info alive after the handle has
died, since we should no longer be trying to operate on any assets once
their handles have been dropped.
## Testing
- I added a `break` in `handle_internal_asset_events`
(`crates/bevy_asset/src/server/mod.rs` on line 1152). I don't believe
this should affect correctness, only efficiency, since it is effectively
only allowing one asset event to be handled per frame. This causes
examples like `animated_fox` to produce the issue fairly frequently.
- I wrote a small program which called `AssetServer::reload` and could
trigger it too.
---
## Changelog
- Fixed an issue which could cause a panic when loading an asset which
was no longer referenced.
---
## Remaining Work
~This needs more testing. I don't yet have a complete project that
reliably crashes without changes to bevy.~ We have at least one vote of
confidence so far from @Testare who had a project broken by this bug.
@cart, (sorry for the ping), I believe you added the code which delays
`remove_dropped`. Was there any other reason `track_assets` needed to
keep the dropped assets alive?
# Objective
- `Rotation2d` is a very long name for a commonly used type.
## Solution
- Rename it to `Rot2` to match `glam`'s naming convention (e.g. `Vec2`)
I ran a poll, and `Rot2` was the favorite of the candidate names.
This is not actually a breaking change, since `Rotation2d` has not been
shipped yet.

# Objective
If you try to add an object to the hashmap that is not capable of
hashing, the program panics. For easier debugging, the type for that
object should be included in the error message.
Fixes#13646.
## Solution
initially i tried calling std::any::type_name_of_val. this had the
problem that it would print something like dyn Box<dyn Reflect>, not
helpful. But since these objects all implement Reflect, i used
Reflect::type_path() instead. Previously, the error message was part of
a constant called HASH_ERROR. i changed that to a macro called
hash_error to print the type of that object more easily
## Testing
i adapted the unit test reflect_map_no_hash to expect the type in that
panic aswell
since this is my first contribution, please let me know if i have done
everything properly
# Objective
- Due to coherency, it was previously not possible to implement
`Bounded3d` for `Extrusion<MyCustomPrimitive>`. This PR fixes that.
## Solution
- Added a new trait `BoundedExtrusion: Primitive2d + Bounded2d` which
provides functions for bounding boxes and spheres of extrusions of 2D
primitives.
- Changed all implementations of `Bounded3d for Extrusion<T>` to
`BoundedExtrusion for T`
- Implemented `Bounded3d for Extrusion<T: BoundedExtrusion>`
- Removed the `extrusion_bounding_box` and `extrusion_bounding_sphere`
functions and used them as default implementations in `BoundedExtrusion`
## Testing
- This PR does not change any implementations

# Objective
- On macOS, closing a window by respawning its entity freezes
## Solution
- `WindowWrapper` is keeping an `Arc` of the window, to be able to
access it from the rendering thread. Winit windows are closed when they
are dropped. This need to happen on the main thread on macOS
- Dropping it as soon as the window is closed means the last remaining
`Arc` will be in the rendering thread
- This PR keeps the `Arc` for one frame in the rendering thread before
actually dropping it
# Objective
Fill the gap in this functionality by implementing it for `Rotation2d`.
We have this already for `Quat` in addition to the direction types.
## Solution
`bevy_math::sampling` now contains an implementation of
`Distribution<Rotation2d>` for `Standard`, along with the associated
convenience implementation `Rotation2d: FromRng`, which allows syntax
like this for creating a random rotation:
```rust
// With `FromRng`:
let rotation = Rotation2d::from_rng(rng);
// With `rand::random`:
let another_rotation: Rotation2d = random();
// With `Rng::gen`:
let yet_another_rotation: Rotation2d = rng.gen();
```
I also cleaned up the documentation a little bit, seeding the `Rng`s
instead of building them from entropy, along with adding a handful of
inline directives.
# Objective
Skip unnecessary blit then tonemapping is set to none.
## Testing
Only tested locally on our app.
## Changelog
Changed tonemapping not to execute in case it is set to none.

This was adopted from #12878. I rebased the changes resolved the
following merge conflicts:
- moved over the changes originally done in bevy_winit/src/lib.rs's
`handle_winit_event` into bevy_winit/src/state.rs's `window_event`
function
- moved WinitEvent::KeyboardFocusLost event forwarding originally done
in bevy_winit/src/winit_event.rs to the equivalent in
bevy_winit/src/state.rs
Tested this by following the modified keyboard_input example from the
original PR.
First, I verified I could reproduce the issue without the changes. Then,
after applying the changes, I verified that when I Alt+Tabbed away from
the running example that the log showed I released Alt and when I tabbed
back it didn't behave like Alt was stuck.
The following is from the original pull request by @gavlig
# Objective
This helps avoiding stuck key presses after switching from and back to
Bevy window. Key press event gets stuck because window loses focus
before receiving a key release event thus we end up with false positive
in ButtonInput.
## Solution
I saw two ways to fix this:
1. add bevy_window as dependency and read WindowFocus events
2. add a KeyboardFocusLost event specifically for this.
I chose the latter because adding another dependency felt wrong, but if
that is more preferable changing this pr won't be a problem. Also if
someone sees another way please let me know.
To test the bug use this small modification over
examples/keyboard_input.rs: (it will work only if you have Alt-Tab
combination for switching between windows in your OS, otherwise change
AltLeft accordingly)
```
//! Demonstrates handling a key press/release.
use bevy::{prelude::*, input:⌨️:KeyboardInput};
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_systems(Update, keyboard_input_system)
.run();
}
/// This system prints 'Alt' key state
fn keyboard_input_system(keyboard_input: Res<ButtonInput<KeyCode>>, mut
keyboard_input_events: EventReader<KeyboardInput>) {
for event in keyboard_input_events.read() {
info!("{:?}", event);
}
if keyboard_input.pressed(KeyCode::AltLeft) {
info!("'Alt' currently pressed");
}
if keyboard_input.just_pressed(KeyCode::AltLeft) {
info!("'Alt' just pressed");
}
if keyboard_input.just_released(KeyCode::AltLeft) {
info!("'Alt' just released");
}
}
```
Here i made a quick video with demo of the fix:
https://youtu.be/qTvUCk4IHvo In first part i press Alt and Alt+Tab to
switch back and forth from example app, logs will indicate that too. In
second part I applied fix and you'll see that Alt will no longer be
pressed when window gets unfocused

- Implement `Extrudable` for all meshbuilders of shapes that have been
added after #13478 was created

# Objective
The default app runner fabricates exit codes loosing useful info in the
process.
## Solution
- Make run_once extract the correct exit code from app.
- Add a test to confirm it works.
## Testing
- Run the `runner_returns_correct_exit_code` test.
- Rejoice when it succeeds.
# Objective
- Implement `Meshable` for `Extrusion<T>`
## Solution
- `Meshable` requires `Meshable::Output: MeshBuilder` now. This means
that all `some_primitive.mesh()` calls now return a `MeshBuilder`. These
were added for primitives that did not have one prior to this.
- A new trait `Extrudable: MeshBuilder` has been added. This trait
allows you to specify the indices of the perimeter of the mesh created
by this `MeshBuilder` and whether they are to be shaded smooth or flat.
- `Extrusion<P: Primitive2d + Meshable>` is now `Meshable` aswell. The
associated `MeshBuilder` is `ExtrusionMeshBuilder` which is generic over
`P` and uses the `MeshBuilder` of its baseshape internally.
- `ExtrusionMeshBuilder` exposes the configuration functions of its
base-shapes builder.
- Updated the `3d_shapes` example to include `Extrusion`s
## Migration Guide
- Depending on the context, you may need to explicitly call
`.mesh().build()` on primitives where you have previously called
`.mesh()`
- The `Output` type of custom `Meshable` implementations must now derive
`MeshBuilder`.
## Additional information
- The extrusions UVs are done so that
- the front face (`+Z`) is in the area between `(0, 0)` and `(0.5,
0.5)`,
- the back face (`-Z`) is in the area between `(0.5, 0)` and `(1, 0.5)`
- the mantle is in the area between `(0, 0.5)` and `(1, 1)`. Each
`PerimeterSegment` you specified in the `Extrudable` implementation will
be allocated an equal portion of this area.
- The UVs of the base shape are scaled to be in the front/back area so
whatever method of filling the full UV-space the base shape used is how
these areas will be filled.
Here is an example of what that looks like on a capsule:
https://github.com/bevyengine/bevy/assets/62256001/425ad288-fbbc-4634-9d3f-5e846cdce85f

- Implemented `Bounded3d` for all 2D `bevy_math` primitives with the
exception of `Plane2d`. As far as I can see, `Plane2d` is pretty much a
line? and I think it is very unintuitive to extrude a plane and get a
plane as a result.
- Add `extrusion_bounding_box` and `extrusion_bounding_sphere`. These
are not always used internally since there are faster methods for
specific extrusions. Both of them produce the optimal result within
precision limits though.
## Testing
- Bounds for extrusions are tested within the same module. All unique
implementations are tested.
- The correctness was validated visually aswell.

This commit implements a large subset of [*subpixel morphological
antialiasing*], better known as SMAA. SMAA is a 2011 antialiasing
technique that detects jaggies in an aliased image and smooths them out.
Despite its age, it's been a continual staple of games for over a
decade. Four quality presets are available: *low*, *medium*, *high*, and
*ultra*. I set the default to *high*, on account of modern GPUs being
significantly faster than they were in 2011.
Like the already-implemented FXAA, SMAA works on an unaliased image.
Unlike FXAA, it requires three passes: (1) edge detection; (2) blending
weight calculation; (3) neighborhood blending. Each of the first two
passes writes an intermediate texture for use by the next pass. The
first pass also writes to a stencil buffer in order to dramatically
reduce the number of pixels that the second pass has to examine. Also
unlike FXAA, two built-in lookup textures are required; I bundle them
into the library in compressed KTX2 format.
The [reference implementation of SMAA] is in HLSL, with abundant use of
preprocessor macros to achieve GLSL compatibility. Unfortunately, the
reference implementation predates WGSL by over a decade, so I had to
translate the HLSL to WGSL manually. As much as was reasonably possible
without sacrificing readability, I tried to translate line by line,
preserving comments, both to aid reviewing and to allow patches to the
HLSL to more easily apply to the WGSL. Most of SMAA's features are
supported, but in the interests of making this patch somewhat less huge,
I skipped a few of the more exotic ones:
* The temporal variant is currently unsupported. This is and has been
used in shipping games, so supporting temporal SMAA would be useful
follow-up work. It would, however, require some significant work on TAA
to ensure compatibility, so I opted to skip it in this patch.
* Depth- and chroma-based edge detection are unimplemented; only luma
is. Depth is lower-quality, but faster; chroma is higher-quality, but
slower. Luma is the suggested default edge detection algorithm. (Note
that depth-based edge detection wouldn't work on WebGL 2 anyway, because
of the Naga bug whereby depth sampling is miscompiled in GLSL. This is
the same bug that prevents depth of field from working on that
platform.)
* Predicated thresholding is currently unsupported.
* My implementation is incompatible with SSAA and MSAA, unlike the
original; MSAA must be turned off to use SMAA in Bevy. I believe this
feature was rarely used in practice.
The `anti_aliasing` example has been updated to allow experimentation
with and testing of the different SMAA quality presets. Along the way, I
refactored the example's help text rendering code a bit to eliminate
code repetition.
SMAA is fully supported on WebGL 2.
Fixes#9819.

# Objective
- Other render resources have a convenient `.binding()` helper function
to get the binding to the resource
## Solution
- Add the same thing to `BufferVec`, `RawBufferVec`, and
`UninitBufferVec`
# Objective
Add slice based variants of existing `get_many_entities` functions on
`World`. This allows for a collection of entries to be looked up mutably
or immutably instead of requiring a compile time constant number.
## Solution
We just take slices and return Vectors.
the following functions have been added:
- `get_many_entities_dynamic`
- `get_many_entities_dynamic_mut`
- `get_many_entities_from_set_mut`
## Testing
- Doc tests, which pass when run through Miri
# Objective
Filling a hole in the API: Previously, there was no particularly
ergonomic way to go from, e.g., a pair of directions to the rotation
that links them.
## Solution
We introduce a small suite of API methods to `Dir2` to address this:
```rust
/// Get the rotation that rotates this direction to `other`.
pub fn rotation_to(self, other: Self) -> Rotation2d { //... }
/// Get the rotation that rotates `other` to this direction.
pub fn rotation_from(self, other: Self) -> Rotation2d { //... }
/// Get the rotation that rotates the X-axis to this direction.
pub fn rotation_from_x(self) -> Rotation2d { //... }
/// Get the rotation that rotates this direction to the X-axis.
pub fn rotation_to_x(self) -> Rotation2d { //... }
/// Get the rotation that rotates this direction to the Y-axis.
pub fn rotation_from_y(self) -> Rotation2d { //... }
/// Get the rotation that rotates the Y-axis to this direction.
pub fn rotation_to_y(self) -> Rotation2d { //... }
```
I also removed some language from the `Rotation2d` docs that is
misleading: the radian and angle conversion functions are already clear
about which angles they spit out, and `Rotation2d` itself doesn't have
any bounds on angles or anything.
# Objective
This PR addresses one of the issues from [discord state
discussion](https://discord.com/channels/691052431525675048/1237949214017716356).
Same-state transitions can be desirable, so there should exist a hook
for them.
Fixes https://github.com/bevyengine/bevy/issues/9130.
## Solution
- Allow `StateTransitionEvent<S>` to contain identity transitions.
- Ignore identity transitions at schedule running level (`OnExit`,
`OnTransition`, `OnEnter`).
- Propagate identity transitions through `SubStates` and
`ComputedStates`.
- Add example about registering custom transition schedules.
## Changelog
- `StateTransitionEvent<S>` can be emitted with same `exited` and
`entered` state.
