`EntityMut::move_entity_from_remove` had two soundness bugs:
- When removing the entity from the archetype, the swapped entity had its table row updated to the same as the removed entity's
- When removing the entity from the table, the swapped entity did not have its table row updated
`BundleInsert::insert` had two/three soundness bugs
- When moving an entity to a new archetype from an `insert`, the swapped entity had its table row set to a different entities
- When moving an entity to a new table from an `insert`, the swapped entity did not have its table row updated
See added tests for examples that trigger those bugs
`EntityMut::despawn` had two soundness bugs
- When despawning an entity, the swapped entity had its table row set to a different entities even if the table didnt change
- When despawning an entity, the swapped entity did not have its table row updated
# Objective
This adds small comment to window fall through example that it won't work on specific platforms. This information is documented in `Cursor` api but I think it is worth to add it in example description for clarity sake.
# Objective
- A more intuitive distinction between the two. `remove_intersection` is verbose and unclear.
- `EntityMut::remove` and `Commands::remove` should match.
## Solution
- What the title says.
---
## Migration Guide
Before
```rust
fn clear_children(parent: Entity, world: &mut World) {
if let Some(children) = world.entity_mut(parent).remove::<Children>() {
for &child in &children.0 {
world.entity_mut(child).remove_intersection::<Parent>();
}
}
}
```
After
```rust
fn clear_children(parent: Entity, world: &mut World) {
if let Some(children) = world.entity_mut(parent).take::<Children>() {
for &child in &children.0 {
world.entity_mut(child).remove::<Parent>();
}
}
}
```
# Objective
Common run conditions can be very useful for quick and ergonomic changes to when a system runs.
Specifically what I'd like to be able to do is
```rust
use bevy::prelude::*;
use bevy::input::common_conditions::input_toggle_active;
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_plugin(
bevy_inspector_egui::quick::WorldInspectorPlugin::default()
.run_if(input_toggle_active(true, KeyCode::Escape)
)
.run();
}
```
## Solution
- add `bevy_input::common_conditions` module with `input_toggle_active`, `input_pressed`, `input_just_pressed`, `input_just_released`
## Changelog
- added common run conditions for `bevy_input`
- you can now use `.add_system(jump.run_if(input_just_pressed(KeyCode::Space)))`
# Objective
There were a couple primitive types missing from the default `TypeRegistry` constructor.
## Solution
Added the missing registrations for `char` and `String`.
# Objective
A couple of places in `bevy_app` use a scoped block that doesn't do anything. I imagine these are a relic from when `Mut<T>` implemented `Drop` in the early days of bevy.
## Solution
Remove the scopes.
# Objective
Support the following syntax for adding systems:
```rust
App::new()
.add_system(setup.on_startup())
.add_systems((
show_menu.in_schedule(OnEnter(GameState::Paused)),
menu_ssytem.in_set(OnUpdate(GameState::Paused)),
hide_menu.in_schedule(OnExit(GameState::Paused)),
))
```
## Solution
Add the traits `IntoSystemAppConfig{s}`, which provide the extension methods necessary for configuring which schedule a system belongs to. These extension methods return `IntoSystemAppConfig{s}`, which `App::add_system{s}` uses to choose which schedule to add systems to.
---
## Changelog
+ Added the extension methods `in_schedule(label)` and `on_startup()` for configuring the schedule a system belongs to.
## Future Work
* Replace all uses of `add_startup_system` in the engine.
* Deprecate this method
Alternative to #7804
Allows other instances of the `sync_simple_transforms` and `propagate_transforms` systems to be added.

# Objective
While working on #7784, I noticed that a `#define VAR` in a `.wgsl` file is always effective, even if it its scope is not accepting lines.
Example:
```c
#define A
#ifndef A
#define B
#endif
```
Currently, `B` will be defined although it shouldn't. This PR fixes that.
## Solution
Move the branch responsible for `#define` lines into the last else branch, which is only evaluated if the current scope is accepting lines.
# Objective
- `bevy_text` used to be "optional". the feature could be disabled, which meant that the systems were not added but `bevy_text` was still compiled because of a hard dependency in `bevy_ui`
- Running something without `bevy_text` enabled and with `bevy_ui` enabled now crashes:
```
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', /bevy/crates/bevy_ecs/src/schedule/schedule.rs:1147:34
```
- This is because `bevy_ui` declares some of its systems in ambiguity sets with systems from `bevy_text`, which were not added if `bevy_text` is disabled
## Solution
- Make `bevy_text` completely optional
## Migration Guide
- feature `bevy_text` now completely removes `bevy_text` from the dependencies when not enabled. Enable feature `bevy_text` if you use Bevy to render text
# Objective
While we use `#[doc(hidden)]` to try and hide marker generics from the user, these types reveal themselves in compiler errors, adding visual noise and confusion.
## Solution
Replace the `AlreadyWasSystem` marker generic with `()`, to reduce visual noise in error messages. This also makes it possible to return `impl Condition<()>` from combinators.
For function systems, use their function signature as the marker type. This should drastically improve the legibility of some error messages.
The `InputMarker` type has been removed, since it is unnecessary.
# Objective
Several places in the ECS use marker generics to avoid overlapping trait implementations, but different places alternately refer to it as `Params` and `Marker`. This is potentially confusing, since it might not be clear that the same pattern is being used. Additionally, users might be misled into thinking that the `Params` type corresponds to the `SystemParam`s of a system.
## Solution
Rename `Params` to `Marker`.
# Objective
There was PR that introduced support for storage buffer is `AsBindGroup` macro [#6129](https://github.com/bevyengine/bevy/pull/6129), but it does not give more granular control over storage buffer, it will always copy all the data no matter which part of it was updated. There is also currently another open PR #6669 that tries to achieve exactly that, it is just not up to date and seems abandoned (Sorry if that is not right). In this PR I'm proposing a solution for both of these approaches to co-exist using `#[storage(n, buffer)]` and `#[storage(n)]` to distinguish between the cases.
We could also discuss in this PR if there is a need to extend this support to DynamicBuffers as well.
# Objective
Fixes#3980
## Solution
Added examples to show how to run a `Schedule`, one with a unique system, and another with several systems
---
## Changelog
- Added: examples in docs to show how to run a `Schedule`
Co-authored-by: remiCzn <77072160+remiCzn@users.noreply.github.com>
# Objective
The `BoxedCondition` type alias does not require the underlying system to be read-only.
## Solution
Define the type alias using `ReadOnlySystem` instead of `System`.
Graph theory make head hurty. Closes#7367.
Basically, when we topologically sort the dependency graph, we already find its strongly-connected components (a really [neat algorithm][1]). This PR adds an algorithm that can dissect those into simple cycles, giving us more useful error reports.
test: `system_build_errors::dependency_cycle`
```
schedule has 1 before/after cycle(s):
cycle 1: system set 'A' must run before itself
system set 'A'
... which must run before system set 'B'
... which must run before system set 'A'
```
```
schedule has 1 before/after cycle(s):
cycle 1: system 'foo' must run before itself
system 'foo'
... which must run before system 'bar'
... which must run before system 'foo'
```
test: `system_build_errors::hierarchy_cycle`

# Objective
`cargo run -p ci` is currently failing locally for me.
```
error: variables can be used directly in the `format!` string

106 | let uuid = Uuid::parse_str(&uuid).map_err(|err| input.error(format!("{}", err)))?;
```
It's not clear to me why CI/clippy didn't pick this up in #6633.
Add some more useful common run conditions.
Some of these existed in `iyes_loopless`. I know people used them, and it would be a regression for those users, when they try to migrate to new Bevy stageless, if they are missing.
I also took the opportunity to add a few more new ones.
---
## Changelog
### Added
- More "common run conditions": on_event, resource change detection, state_changed, any_with_component
# Objective
`TextBundle` should have a `BackgroundColor` component.
Apart from adding emphasis etc to text, adding a background color to text nodes can be extremely useful for understanding how Bevy aligns, sizes and positions text, and identifying and debugging problems.
It's easy for users to insert the `BackgroundColor` component themselves but not immediately obvious or discoverable that it's possible. A `BackgroundColor` component allows us to add a `with_background_color` helper function to `TextBundle`.
related issue: #5935
## Solution
Add a `BackgroundColor` component to `TextBundle`.
---
## Changelog
* Added a `BackgroundColor` component to `TextBundle`.
* Added a helper method `with_background_color` to `TextBundle`.
## Migration Guide
`TextBundle` now has a `BackgroundColor` component.
Use `TextBundle`'s `background_color` field or the `with_background_color` method to set a background color for text when spawning a text node, in place of manual insertion of a `BackgroundColor` component.
# Objective
When working on #7750 I noticed that `CoreSchedule::Main` was explicitly used to get the schedule for the `OnUpdate` set. This can lead to failures or weird behavior if `add_state` is used with a differently configured `default_schedule_label`, because the other systems are added to the default schedule. This PR fixes that.
## Solution
Use `default_schedule_label` to retrieve a single schedule to which all systems are added.
# Objective
Fix#5026.
## Solution
Only make a `trace!` log if the event count changed.
---
## Changelog
Changed: `EventWriter::send_batch` will only log a TRACE level log if the batch is non-empty.
# Objective
- Adds foundational math for Bezier curves, useful for UI/2D/3D animation and smooth paths.
https://user-images.githubusercontent.com/2632925/218883143-e138f994-1795-40da-8c59-21d779666991.mp4
## Solution
- Adds the generic `Bezier` type, and a `Point` trait. The `Point` trait allows us to use control points of any dimension, as long as they support vector math. I've implemented it for `f32`(1D), `Vec2`(2D), and `Vec3`/`Vec3A`(3D).
- Adds `CubicBezierEasing` on top of `Bezier` with the addition of an implementation of cubic Bezier easing, which is a foundational tool for UI animation.
- This involves solving for $t$ in the parametric Bezier function $B(t)$ using the Newton-Raphson method to find a value with error $\leq$ 1e-7, capped at 8 iterations.
- Added type aliases for common Bezier curves: `CubicBezier2d`, `CubicBezier3d`, `QuadraticBezier2d`, and `QuadraticBezier3d`. These types use `Vec3A` to represent control points, as this was found to have an 80-90% speedup over using `Vec3`.
- Benchmarking shows quadratic/cubic Bezier evaluations $B(t)$ take \~1.8/2.4ns respectively. Easing, which requires an iterative solve takes \~50ns for cubic Beziers.
---
## Changelog
- Added `CubicBezier2d`, `CubicBezier3d`, `QuadraticBezier2d`, and `QuadraticBezier3d` types with methods for sampling position, velocity, and acceleration. The generic `Bezier` type is also available, and generic over any degree of Bezier curve.
- Added `CubicBezierEasing`, with additional methods to allow for smooth easing animations.
# Objective
Fix#7584.
## Solution
Add an abstraction for creating custom system combinators with minimal boilerplate. Use this to implement AND/OR combinators. Use this to simplify the implementation of `PipeSystem`.
## Example
Feel free to bikeshed on the syntax.
I chose the names `and_then`/`or_else` to emphasize the fact that these short-circuit, while I chose method syntax to empasize that the arguments are *not* treated equally.
```rust
app.add_systems((
my_system.run_if(resource_exists::<R>().and_then(resource_equals(R(0)))),
our_system.run_if(resource_exists::<R>().or_else(resource_exists::<S>())),
));
```
---
## Todo
- [ ] Decide on a syntax
- [x] Write docs
- [x] Write tests
## Changelog
+ Added the extension methods `.and_then(...)` and `.or_else(...)` to run conditions, which allows combining run conditions with short-circuiting behavior.
+ Added the trait `Combine`, which can be used with the new `CombinatorSystem` to create system combinators with custom behavior.
# Objective
- Fixes#7636.
## Solution
`apply_state_transitions::<S>` runs in `CoreSet::StateTransitions` which is already scheduled before `CoreSet::Update`. Therefore explicitly scheduling `OnUpdate` after `apply_state_transitions::<S>` is not necessary.
# Objective
- Fixes#7442.
## Solution
- Added `report_sets` option to `ScheduleBuildSettings` like described in the linked issue.
The output of the `3d_scene` example when reporting ambiguities with `report_sets` and `use_shortnames` set to `true` (and with #7755 applied) now looks like this:
```
82 pairs of systems with conflicting data access have indeterminate execution order. Consider adding `before`, `after`, or `ambiguous_with` relationships between these:

# Objective
While working on #7442 i discovered that `get_short_name` does not work well with sub paths after closing brackets. It currently turns `bevy_asset::assets::Assets<bevy_scene::dynamic_scene::DynamicScene>::asset_event_system` into `Assets<DynamicScene>asset_event_system`. This PR fixes that.
## Solution
- Retain `::` after a closing bracket like `>`, `)` or `]`.
- Add a test for all sub path after closing bracket cases.
# Objective
- Add basic spatial audio support to Bevy
- this is what rodio supports, so no HRTF, just simple stereo channel manipulation
- no "built-in" ECS support: `Emitter` and `Listener` should be components that would automatically update the positions
This PR goal is to just expose rodio functionality, made possible with the recent update to rodio 0.16. A proper ECS integration opens a lot more questions, and would probably require an RFC
Also updates rodio and fixes#6122
# Objective
Allow using `Local<WorldId>` in systems.
## Solution
- Describe the solution used to achieve the objective above.
---
## Changelog
+ `WorldId` now implements the `FromWorld` trait.
Adds documentation for setting up bevy on Alpine Linux and its derivatives.
It contains instructions on installing the required packages and also fixing runtime errors.
# Objective
- Nothing render
```
ERROR bevy_render::render_resource::pipeline_cache: failed to process shader: Invalid shader def definition for '_import_path': bevy_pbr
```
## Solution
- Fix define regex so that it must have one whitespace after `define`
# Objective
- Fixes#7494
- It is now possible to define a ShaderDef from inside a shader. This can be useful to centralise a value, or making sure an import is only interpreted once
## Solution
- Support `#define <SHADERDEF_NAME> <optional value>`
# Objective
- ambiguities bad
## Solution
- solve ambiguities
- by either ignoring (e.g. on `queue_mesh_view_bind_groups` since `LightMeta` access is different)
- by introducing a dependency (`prepare_windows -> prepare_*` because the latter use the fallback Msaa)
- make `prepare_assets` public so that we can do a proper `.after`
# Objective
Currently, it is quite awkward to use the `pbr` function in a custom shader without binding a mesh bind group.
This is because the `pbr` function depends on the `MESH_FLAGS_SHADOW_RECEIVER_BIT` flag.
## Solution
I have removed this dependency by adding the flag as a parameter to the `PbrInput` struct.
I am not sure if this is the ideal solution since the mesh flag indicates both `MESH_FLAGS_SIGN_DETERMINANT_MODEL_3X3_BIT` and `MESH_FLAGS_SHADOW_RECEIVER_BIT`.
The former seems to be unrelated to PBR. Maybe the flag should be split.
# Objective
- Fix the environment map shader not working under webgl due to textureNumLevels() not being supported
- Fixes https://github.com/bevyengine/bevy/issues/7722
## Solution
- Instead of using textureNumLevels(), put an extra field in the GpuLights uniform to store the mip count
# Objective
Splits tone mapping from https://github.com/bevyengine/bevy/pull/6677 into a separate PR.
Address https://github.com/bevyengine/bevy/issues/2264.
Adds tone mapping options:
- None: Bypasses tonemapping for instances where users want colors output to match those set.
- Reinhard
- Reinhard Luminance: Bevy's exiting tonemapping
- [ACES](https://github.com/TheRealMJP/BakingLab/blob/master/BakingLab/ACES.hlsl) (Fitted version, based on the same implementation that Godot 4 uses) see https://github.com/bevyengine/bevy/issues/2264
- [AgX](https://github.com/sobotka/AgX)
- SomewhatBoringDisplayTransform
- TonyMcMapface
- Blender Filmic
This PR also adds support for EXR images so they can be used to compare tonemapping options with reference images.
## Migration Guide
- Tonemapping is now an enum with NONE and the various tonemappers.
- The DebandDither is now a separate component.

…top sort. reduce mem alloc
# Objective
- Reduce alloc count.
- Improve code quality.
## Solution
- use `TarjanScc::run` directly, which calls a closure with each scc, in closure, we can detect cycles and flatten nodes
# Objective
`ChangeTrackers<>` is a `WorldQuery` type that lets you access the change ticks for a component. #7097 has added `Ref<>`, which gives access to a component's value in addition to its change ticks. Since bevy's access model does not separate a component's value from its change ticks, there is no benefit to using `ChangeTrackers<T>` over `Ref<T>`.
## Solution
Deprecate `ChangeTrackers<>`.
---
## Changelog
* `ChangeTrackers<T>` has been deprecated. It will be removed in Bevy 0.11.
## Migration Guide
`ChangeTrackers<T>` has been deprecated, and will be removed in the next release. Any usage should be replaced with `Ref<T>`.
```rust
// Before (0.9)
fn my_system(q: Query<(&MyComponent, ChangeTrackers<MyComponent>)>) {
for (value, trackers) in &q {
if trackers.is_changed() {
// Do something with `value`.
}
}
}
// After (0.10)
fn my_system(q: Query<Ref<MyComponent>>) {
for value in &q {
if value.is_changed() {
// Do something with `value`.
}
}
}
```
# Objective
- Updates list of plugins and feature information in `DefaultPlugins` doc comment
- Solve the short term issue of https://github.com/bevyengine/bevy/issues/7332
## Solution
- Update doc comment to reflect current implementation
- Sort plugins by appearance in implementation
