Remove stepping from default features (#12847)
# Objective Fix #11931 ## Solution - Make stepping a non-default feature - Adjust documentation and examples - In particular, make the breakout example not show the stepping prompt if compiled without the feature (shows a log message instead) --- ## Changelog - Removed `bevy_debug_stepping` from default features ## Migration Guide The system-by-system stepping feature is now disabled by default; to use it, enable the `bevy_debug_stepping` feature explicitly: ```toml [dependencies] bevy = { version = "0.14", features = ["bevy_debug_stepping"] } ``` Code using [`Stepping`](https://docs.rs/bevy/latest/bevy/ecs/schedule/struct.Stepping.html) will still compile with the feature disabled, but will print a runtime error message to the console if the application attempts to enable stepping. --------- Co-authored-by: James Liu <contact@jamessliu.com> Co-authored-by: François Mockers <francois.mockers@vleue.com> |

Move close_on_esc to bevy_dev_tools (#12855)
# Objective - As @james7132 said [on Discord](https://discord.com/channels/691052431525675048/692572690833473578/1224626740773523536), the `close_on_esc` system is forcing `bevy_window` to depend on `bevy_input`. - `close_on_esc` is not likely to be used in production, so it arguably does not have a place in `bevy_window`. ## Solution - As suggested by @afonsolage, move `close_on_esc` into `bevy_dev_tools`. - Add an example to the documentation too. - Remove `bevy_window`'s dependency on `bevy_input`. - Add `bevy_reflect`'s `smol_str` feature to `bevy_window` because it was implicitly depended upon with `bevy_input` before it was removed. - Remove any usage of `close_on_esc` from the examples. - `bevy_dev_tools` is not enabled by default. I personally find it frustrating to run examples with additional features, so I opted to remove it entirely. - This is up for discussion if you have an alternate solution. --- ## Changelog - Moved `bevy_window::close_on_esc` to `bevy_dev_tools::close_on_esc`. - Removed usage of `bevy_dev_tools::close_on_esc` from all examples. ## Migration Guide `bevy_window::close_on_esc` has been moved to `bevy_dev_tools::close_on_esc`. You will first need to enable `bevy_dev_tools` as a feature in your `Cargo.toml`: ```toml [dependencies] bevy = { version = "0.14", features = ["bevy_dev_tools"] } ``` Finally, modify any imports to use `bevy_dev_tools` instead: ```rust // Old: // use bevy:🪟:close_on_esc; // New: use bevy::dev_tools::close_on_esc; App::new() .add_systems(Update, close_on_esc) // ... .run(); ``` |

Breakout refactor (#12477)
# Objective - Improve the code quality of the breakout example - As a newcomer to `bevy` I was pointed to the breakout example after the "Getting Started" tutorial - I'm making this PR because it had a few wrong comments + some inconsistency in used patterns ## Solution - Remove references to `wall` in all the collision code as it also handles bricks and the paddle - Use the newtype pattern with `bevy::prelude::Deref` for resources - It was already used for `Velocity` before this PR - `Scoreboard` is a resource only containing `score`, so it's simpler as a newtype `Score` resource - `CollisionSound` is already a newtype, so might as well unify the access pattern for it - Added docstrings for `WallLocation::position` and `WallLocation::size` to explain what they represent |

Fix z scale being 0.0 in breakout example (#12439)
# Objective Scaling `z` by anything but `1.0` in 2d can only lead to bugs and confusion. See #4149. ## Solution Use a `Vec2` for the paddle size const, and add a scale of `1.0` later. This matches the way `BRICK_SIZE` is defined. |

Migrate from LegacyColor to bevy_color::Color (#12163)
# Objective - As part of the migration process we need to a) see the end effect of the migration on user ergonomics b) check for serious perf regressions c) actually migrate the code - To accomplish this, I'm going to attempt to migrate all of the remaining user-facing usages of `LegacyColor` in one PR, being careful to keep a clean commit history. - Fixes #12056. ## Solution I've chosen to use the polymorphic `Color` type as our standard user-facing API. - [x] Migrate `bevy_gizmos`. - [x] Take `impl Into<Color>` in all `bevy_gizmos` APIs - [x] Migrate sprites - [x] Migrate UI - [x] Migrate `ColorMaterial` - [x] Migrate `MaterialMesh2D` - [x] Migrate fog - [x] Migrate lights - [x] Migrate StandardMaterial - [x] Migrate wireframes - [x] Migrate clear color - [x] Migrate text - [x] Migrate gltf loader - [x] Register color types for reflection - [x] Remove `LegacyColor` - [x] Make sure CI passes Incidental improvements to ease migration: - added `Color::srgba_u8`, `Color::srgba_from_array` and friends - added `set_alpha`, `is_fully_transparent` and `is_fully_opaque` to the `Alpha` trait - add and immediately deprecate (lol) `Color::rgb` and friends in favor of more explicit and consistent `Color::srgb` - standardized on white and black for most example text colors - added vector field traits to `LinearRgba`: ~~`Add`, `Sub`, `AddAssign`, `SubAssign`,~~ `Mul<f32>` and `Div<f32>`. Multiplications and divisions do not scale alpha. `Add` and `Sub` have been cut from this PR. - added `LinearRgba` and `Srgba` `RED/GREEN/BLUE` - added `LinearRgba_to_f32_array` and `LinearRgba::to_u32` ## Migration Guide Bevy's color types have changed! Wherever you used a `bevy::render::Color`, a `bevy::color::Color` is used instead. These are quite similar! Both are enums storing a color in a specific color space (or to be more precise, using a specific color model). However, each of the different color models now has its own type. TODO... - `Color::rgba`, `Color::rgb`, `Color::rbga_u8`, `Color::rgb_u8`, `Color::rgb_from_array` are now `Color::srgba`, `Color::srgb`, `Color::srgba_u8`, `Color::srgb_u8` and `Color::srgb_from_array`. - `Color::set_a` and `Color::a` is now `Color::set_alpha` and `Color::alpha`. These are part of the `Alpha` trait in `bevy_color`. - `Color::is_fully_transparent` is now part of the `Alpha` trait in `bevy_color` - `Color::r`, `Color::set_r`, `Color::with_r` and the equivalents for `g`, `b` `h`, `s` and `l` have been removed due to causing silent relatively expensive conversions. Convert your `Color` into the desired color space, perform your operations there, and then convert it back into a polymorphic `Color` enum. - `Color::hex` is now `Srgba::hex`. Call `.into` or construct a `Color::Srgba` variant manually to convert it. - `WireframeMaterial`, `ExtractedUiNode`, `ExtractedDirectionalLight`, `ExtractedPointLight`, `ExtractedSpotLight` and `ExtractedSprite` now store a `LinearRgba`, rather than a polymorphic `Color` - `Color::rgb_linear` and `Color::rgba_linear` are now `Color::linear_rgb` and `Color::linear_rgba` - The various CSS color constants are no longer stored directly on `Color`. Instead, they're defined in the `Srgba` color space, and accessed via `bevy::color::palettes::css`. Call `.into()` on them to convert them into a `Color` for quick debugging use, and consider using the much prettier `tailwind` palette for prototyping. - The `LIME_GREEN` color has been renamed to `LIMEGREEN` to comply with the standard naming. - Vector field arithmetic operations on `Color` (add, subtract, multiply and divide by a f32) have been removed. Instead, convert your colors into `LinearRgba` space, and perform your operations explicitly there. This is particularly relevant when working with emissive or HDR colors, whose color channel values are routinely outside of the ordinary 0 to 1 range. - `Color::as_linear_rgba_f32` has been removed. Call `LinearRgba::to_f32_array` instead, converting if needed. - `Color::as_linear_rgba_u32` has been removed. Call `LinearRgba::to_u32` instead, converting if needed. - Several other color conversion methods to transform LCH or HSL colors into float arrays or `Vec` types have been removed. Please reimplement these externally or open a PR to re-add them if you found them particularly useful. - Various methods on `Color` such as `rgb` or `hsl` to convert the color into a specific color space have been removed. Convert into `LinearRgba`, then to the color space of your choice. - Various implicitly-converting color value methods on `Color` such as `r`, `g`, `b` or `h` have been removed. Please convert it into the color space of your choice, then check these properties. - `Color` no longer implements `AsBindGroup`. Store a `LinearRgba` internally instead to avoid conversion costs. --------- Co-authored-by: Alice Cecile <alice.i.cecil@gmail.com> Co-authored-by: Afonso Lage <lage.afonso@gmail.com> Co-authored-by: Rob Parrett <robparrett@gmail.com> Co-authored-by: Zachary Harrold <zac@harrold.com.au> |

Rename bevy_render::Color to LegacyColor (#12069)
# Objective The migration process for `bevy_color` (#12013) will be fairly involved: there will be hundreds of affected files, and a large number of APIs. ## Solution To allow us to proceed granularly, we're going to keep both `bevy_color::Color` (new) and `bevy_render::Color` (old) around until the migration is complete. However, simply doing this directly is confusing! They're both called `Color`, making it very hard to tell when a portion of the code has been ported. As discussed in #12056, by renaming the old `Color` type, we can make it easier to gradually migrate over, one API at a time. ## Migration Guide THIS MIGRATION GUIDE INTENTIONALLY LEFT BLANK. This change should not be shipped to end users: delete this section in the final migration guide! --------- Co-authored-by: Alice Cecile <alice.i.cecil@gmail.com> |

Deprecate shapes in bevy_render::mesh::shape (#11773)
# Objective #11431 and #11688 implemented meshing support for Bevy's new geometric primitives. The next step is to deprecate the shapes in `bevy_render::mesh::shape` and to later remove them completely for 0.14. ## Solution Deprecate the shapes and reduce code duplication by utilizing the primitive meshing API for the old shapes where possible. Note that some shapes have behavior that can't be exactly reproduced with the new primitives yet: - `Box` is more of an AABB with min/max extents - `Plane` supports a subdivision count - `Quad` has a `flipped` property These types have not been changed to utilize the new primitives yet. --- ## Changelog - Deprecated all shapes in `bevy_render::mesh::shape` - Changed all examples to use new primitives for meshing ## Migration Guide Bevy has previously used rendering-specific types like `UVSphere` and `Quad` for primitive mesh shapes. These have now been deprecated to use the geometric primitives newly introduced in version 0.13. Some examples: ```rust let before = meshes.add(shape::Box::new(5.0, 0.15, 5.0)); let after = meshes.add(Cuboid::new(5.0, 0.15, 5.0)); let before = meshes.add(shape::Quad::default()); let after = meshes.add(Rectangle::default()); let before = meshes.add(shape::Plane::from_size(5.0)); // The surface normal can now also be specified when using `new` let after = meshes.add(Plane3d::default().mesh().size(5.0, 5.0)); let before = meshes.add( Mesh::try_from(shape::Icosphere { radius: 0.5, subdivisions: 5, }) .unwrap(), ); let after = meshes.add(Sphere::new(0.5).mesh().ico(5).unwrap()); ``` |

System Stepping implemented as Resource (#8453)
# Objective Add interactive system debugging capabilities to bevy, providing step/break/continue style capabilities to running system schedules. * Original implementation: #8063 - `ignore_stepping()` everywhere was too much complexity * Schedule-config & Resource discussion: #8168 - Decided on selective adding of Schedules & Resource-based control ## Solution Created `Stepping` Resource. This resource can be used to enable stepping on a per-schedule basis. Systems within schedules can be individually configured to: * AlwaysRun: Ignore any stepping state and run every frame * NeverRun: Never run while stepping is enabled - this allows for disabling of systems while debugging * Break: If we're running the full frame, stop before this system is run Stepping provides two modes of execution that reflect traditional debuggers: * Step-based: Only execute one system at a time * Continue/Break: Run all systems, but stop before running a system marked as Break ### Demo https://user-images.githubusercontent.com/857742/233630981-99f3bbda-9ca6-4cc4-a00f-171c4946dc47.mov Breakout has been modified to use Stepping. The game runs normally for a couple of seconds, then stepping is enabled and the game appears to pause. A list of Schedules & Systems appears with a cursor at the first System in the list. The demo then steps forward full frames using the spacebar until the ball is about to hit a brick. Then we step system by system as the ball impacts a brick, showing the cursor moving through the individual systems. Finally the demo switches back to frame stepping as the ball changes course. ### Limitations Due to architectural constraints in bevy, there are some cases systems stepping will not function as a user would expect. #### Event-driven systems Stepping does not support systems that are driven by `Event`s as events are flushed after 1-2 frames. Although game systems are not running while stepping, ignored systems are still running every frame, so events will be flushed. This presents to the user as stepping the event-driven system never executes the system. It does execute, but the events have already been flushed. This can be resolved by changing event handling to use a buffer for events, and only dropping an event once all readers have read it. The work-around to allow these systems to properly execute during stepping is to have them ignore stepping: `app.add_systems(event_driven_system.ignore_stepping())`. This was done in the breakout example to ensure sound played even while stepping. #### Conditional Systems When a system is stepped, it is given an opportunity to run. If the conditions of the system say it should not run, it will not. Similar to Event-driven systems, if a system is conditional, and that condition is only true for a very small time window, then stepping the system may not execute the system. This includes depending on any sort of external clock. This exhibits to the user as the system not always running when it is stepped. A solution to this limitation is to ensure any conditions are consistent while stepping is enabled. For example, all systems that modify any state the condition uses should also enable stepping. #### State-transition Systems Stepping is configured on the per-`Schedule` level, requiring the user to have a `ScheduleLabel`. To support state-transition systems, bevy generates needed schedules dynamically. Currently it’s very difficult (if not impossible, I haven’t verified) for the user to get the labels for these schedules. Without ready access to the dynamically generated schedules, and a resolution for the `Event` lifetime, **stepping of the state-transition systems is not supported** --- ## Changelog - `Schedule::run()` updated to consult `Stepping` Resource to determine which Systems to run each frame - Added `Schedule.label` as a `BoxedSystemLabel`, along with supporting `Schedule::set_label()` and `Schedule::label()` methods - `Stepping` needed to know which `Schedule` was running, and prior to this PR, `Schedule` didn't track its own label - Would have preferred to add `Schedule::with_label()` and remove `Schedule::new()`, but this PR touches enough already - Added calls to `Schedule.set_label()` to `App` and `World` as needed - Added `Stepping` resource - Added `Stepping::begin_frame()` system to `MainSchedulePlugin` - Run before `Main::run_main()` - Notifies any `Stepping` Resource a new render frame is starting ## Migration Guide - Add a call to `Schedule::set_label()` for any custom `Schedule` - This is only required if the `Schedule` will be stepped --------- Co-authored-by: Carter Anderson <mcanders1@gmail.com> |

Use IntersectsVolume for breakout example collisions (#11500)
# Objective Fixes #11479 ## Solution - Remove `collide_aabb.rs` - Re-implement the example-specific collision code in the example, taking advantage of the new `IntersectsVolume` trait. ## Changelog - Removed `sprite::collide_aabb::collide` and `sprite::collide_aabb::Collision`. ## Migration Guide `sprite::collide_aabb::collide` and `sprite::collide_aabb::Collision` were removed. ```rust // Before let collision = bevy::sprite::collide_aabb::collide(a_pos, a_size, b_pos, b_size); if collision.is_some() { // ... } // After let collision = Aabb2d::new(a_pos.truncate(), a_size / 2.) .intersects(&Aabb2d::new(b_pos.truncate(), b_size / 2.)); if collision { // ... } ``` If you were making use `collide_aabb::Collision`, see the new `collide_with_side` function in the [`breakout` example](https://bevyengine.org/examples/Games/breakout/). ## Discussion As discussed in the linked issue, maybe we want to wait on `bevy_sprite` generally making use of `Aabb2b` so users don't need to construct it manually. But since they **do** need to construct the bounding circle for the ball manually, this doesn't seem like a big deal to me. --------- Co-authored-by: IQuick 143 <IQuick143cz@gmail.com> |

Use impl Into<A> for Assets::add (#10878)
# Motivation When spawning entities into a scene, it is very common to create assets like meshes and materials and to add them via asset handles. A common setup might look like this: ```rust fn setup( mut commands: Commands, mut meshes: ResMut<Assets<Mesh>>, mut materials: ResMut<Assets<StandardMaterial>>, ) { commands.spawn(PbrBundle { mesh: meshes.add(Mesh::from(shape::Cube { size: 1.0 })), material: materials.add(StandardMaterial::from(Color::RED)), ..default() }); } ``` Let's take a closer look at the part that adds the assets using `add`. ```rust mesh: meshes.add(Mesh::from(shape::Cube { size: 1.0 })), material: materials.add(StandardMaterial::from(Color::RED)), ``` Here, "mesh" and "material" are both repeated three times. It's very explicit, but I find it to be a bit verbose. In addition to being more code to read and write, the extra characters can sometimes also lead to the code being formatted to span multiple lines even though the core task, adding e.g. a primitive mesh, is extremely simple. A way to address this is by using `.into()`: ```rust mesh: meshes.add(shape::Cube { size: 1.0 }.into()), material: materials.add(Color::RED.into()), ``` This is fine, but from the names and the type of `meshes`, we already know what the type should be. It's very clear that `Cube` should be turned into a `Mesh` because of the context it's used in. `.into()` is just seven characters, but it's so common that it quickly adds up and gets annoying. It would be nice if you could skip all of the conversion and let Bevy handle it for you: ```rust mesh: meshes.add(shape::Cube { size: 1.0 }), material: materials.add(Color::RED), ``` # Objective Make adding assets more ergonomic by making `Assets::add` take an `impl Into<A>` instead of `A`. ## Solution `Assets::add` now takes an `impl Into<A>` instead of `A`, so e.g. this works: ```rust commands.spawn(PbrBundle { mesh: meshes.add(shape::Cube { size: 1.0 }), material: materials.add(Color::RED), ..default() }); ``` I also changed all examples to use this API, which increases consistency as well because `Mesh::from` and `into` were being used arbitrarily even in the same file. This also gets rid of some lines of code because formatting is nicer. --- ## Changelog - `Assets::add` now takes an `impl Into<A>` instead of `A` - Examples don't use `T::from(K)` or `K.into()` when adding assets ## Migration Guide Some `into` calls that worked previously might now be broken because of the new trait bounds. You need to either remove `into` or perform the conversion explicitly with `from`: ```rust // Doesn't compile let mesh_handle = meshes.add(shape::Cube { size: 1.0 }.into()), // These compile let mesh_handle = meshes.add(shape::Cube { size: 1.0 }), let mesh_handle = meshes.add(Mesh::from(shape::Cube { size: 1.0 })), ``` ## Concerns I believe the primary concerns might be: 1. Is this too implicit? 2. Does this increase codegen bloat? Previously, the two APIs were using `into` or `from`, and now it's "nothing" or `from`. You could argue that `into` is slightly more explicit than "nothing" in cases like the earlier examples where a `Color` gets converted to e.g. a `StandardMaterial`, but I personally don't think `into` adds much value even in this case, and you could still see the actual type from the asset type. As for codegen bloat, I doubt it adds that much, but I'm not very familiar with the details of codegen. I personally value the user-facing code reduction and ergonomics improvements that these changes would provide, but it might be worth checking the other effects in more detail. Another slight concern is migration pain; apps might have a ton of `into` calls that would need to be removed, and it did take me a while to do so for Bevy itself (maybe around 20-40 minutes). However, I think the fact that there *are* so many `into` calls just highlights that the API could be made nicer, and I'd gladly migrate my own projects for it. |

Update winit dependency to 0.29 (#10702)
# Objective - Update winit dependency to 0.29 ## Changelog ### KeyCode changes - Removed `ScanCode`, as it was [replaced by KeyCode](https://github.com/rust-windowing/winit/blob/master/CHANGELOG.md#0292). - `ReceivedCharacter.char` is now a `SmolStr`, [relevant doc](https://docs.rs/winit/latest/winit/event/struct.KeyEvent.html#structfield.text). - Changed most `KeyCode` values, and added more. KeyCode has changed meaning. With this PR, it refers to physical position on keyboard rather than the printed letter on keyboard keys. In practice this means: - On QWERTY keyboard layouts, nothing changes - On any other keyboard layout, `KeyCode` no longer reflects the label on key. - This is "good". In bevy 0.12, when you used WASD for movement, users with non-QWERTY keyboards couldn't play your game! This was especially bad for non-latin keyboards. Now, WASD represents the physical keys. A French player will press the ZQSD keys, which are near each other, Kyrgyz players will use "Цфыв". - This is "bad" as well. You can't know in advance what the label of the key for input is. Your UI says "press WASD to move", even if in reality, they should be pressing "ZQSD" or "Цфыв". You also no longer can use `KeyCode` for text inputs. In any case, it was a pretty bad API for text input. You should use `ReceivedCharacter` now instead. ### Other changes - Use `web-time` rather than `instant` crate. (https://github.com/rust-windowing/winit/pull/2836) - winit did split `run_return` in `run_onDemand` and `pump_events`, I did the same change in bevy_winit and used `pump_events`. - Removed `return_from_run` from `WinitSettings` as `winit::run` now returns on supported platforms. - I left the example "return_after_run" as I think it's still useful. - This winit change is done partly to allow to create a new window after quitting all windows: https://github.com/emilk/egui/issues/1918 ; this PR doesn't address. - added `width` and `height` properties in the `canvas` from wasm example (https://github.com/bevyengine/bevy/pull/10702#discussion_r1420567168) ## Known regressions (important follow ups?) - Provide an API for reacting when a specific key from current layout was released. - possible solutions: use winit::Key from winit::KeyEvent ; mapping between KeyCode and Key ; or . - We don't receive characters through alt+numpad (e.g. alt + 151 = "ù") anymore ; reproduced on winit example "ime". maybe related to https://github.com/rust-windowing/winit/issues/2945 - (windows) Window content doesn't refresh at all when resizing. By reading https://github.com/rust-windowing/winit/issues/2900 ; I suspect we should just fire a `window.request_redraw();` from `AboutToWait`, and handle actual redrawing within `RedrawRequested`. I'm not sure how to move all that code so I'd appreciate it to be a follow up. - (windows) unreleased winit fix for using set_control_flow in AboutToWait https://github.com/rust-windowing/winit/issues/3215 ; ⚠️ I'm not sure what the implications are, but that feels bad 🤔 ## Follow up I'd like to avoid bloating this PR, here are a few follow up tasks worthy of a separate PR, or new issue to track them once this PR is closed, as they would either complicate reviews, or at risk of being controversial: - remove CanvasParentResizePlugin (https://github.com/bevyengine/bevy/pull/10702#discussion_r1417068856) - avoid mentionning explicitly winit in docs from bevy_window ? - NamedKey integration on bevy_input: https://github.com/rust-windowing/winit/pull/3143 introduced a new NamedKey variant. I implemented it only on the converters but we'd benefit making the same changes to bevy_input. - Add more info in KeyboardInput https://github.com/bevyengine/bevy/pull/10702#pullrequestreview-1748336313 - https://github.com/bevyengine/bevy/pull/9905 added a workaround on a bug allegedly fixed by winit 0.29. We should check if it's still necessary. - update to raw_window_handle 0.6 - blocked by wgpu - Rename `KeyCode` to `PhysicalKeyCode` https://github.com/bevyengine/bevy/pull/10702#discussion_r1404595015 - remove `instant` dependency, [replaced by](https://github.com/rust-windowing/winit/pull/2836) `web_time`), we'd need to update to : - fastrand >= 2.0 - [`async-executor`](https://github.com/smol-rs/async-executor) >= 1.7 - [`futures-lite`](https://github.com/smol-rs/futures-lite) >= 2.0 - Verify license, see [discussion](https://github.com/bevyengine/bevy/pull/8745#discussion_r1402439800) - we might be missing a short notice or description of changes made - Consider using https://github.com/rust-windowing/cursor-icon directly rather than vendoring it in bevy. - investigate [this unwrap](https://github.com/bevyengine/bevy/pull/8745#discussion_r1387044986) (`winit_window.canvas().unwrap();`) - Use more good things about winit's update - https://github.com/bevyengine/bevy/pull/10689#issuecomment-1823560428 ## Migration Guide This PR should have one. |

Unify FixedTime and Time while fixing several problems (#8964)
# Objective Current `FixedTime` and `Time` have several problems. This pull aims to fix many of them at once. - If there is a longer pause between app updates, time will jump forward a lot at once and fixed time will iterate on `FixedUpdate` for a large number of steps. If the pause is merely seconds, then this will just mean jerkiness and possible unexpected behaviour in gameplay. If the pause is hours/days as with OS suspend, the game will appear to freeze until it has caught up with real time. - If calculating a fixed step takes longer than specified fixed step period, the game will enter a death spiral where rendering each frame takes longer and longer due to more and more fixed step updates being run per frame and the game appears to freeze. - There is no way to see current fixed step elapsed time inside fixed steps. In order to track this, the game designer needs to add a custom system inside `FixedUpdate` that calculates elapsed or step count in a resource. - Access to delta time inside fixed step is `FixedStep::period` rather than `Time::delta`. This, coupled with the issue that `Time::elapsed` isn't available at all for fixed steps, makes it that time requiring systems are either implemented to be run in `FixedUpdate` or `Update`, but rarely work in both. - Fixes #8800 - Fixes #8543 - Fixes #7439 - Fixes #5692 ## Solution - Create a generic `Time<T>` clock that has no processing logic but which can be instantiated for multiple usages. This is also exposed for users to add custom clocks. - Create three standard clocks, `Time<Real>`, `Time<Virtual>` and `Time<Fixed>`, all of which contain their individual logic. - Create one "default" clock, which is just `Time` (or `Time<()>`), which will be overwritten from `Time<Virtual>` on each update, and `Time<Fixed>` inside `FixedUpdate` schedule. This way systems that do not care specifically which time they track can work both in `Update` and `FixedUpdate` without changes and the behaviour is intuitive. - Add `max_delta` to virtual time update, which limits how much can be added to virtual time by a single update. This fixes both the behaviour after a long freeze, and also the death spiral by limiting how many fixed timestep iterations there can be per update. Possible future work could be adding `max_accumulator` to add a sort of "leaky bucket" time processing to possibly smooth out jumps in time while keeping frame rate stable. - Many minor tweaks and clarifications to the time functions and their documentation. ## Changelog - `Time::raw_delta()`, `Time::raw_elapsed()` and related methods are moved to `Time<Real>::delta()` and `Time<Real>::elapsed()` and now match `Time` API - `FixedTime` is now `Time<Fixed>` and matches `Time` API. - `Time<Fixed>` default timestep is now 64 Hz, or 15625 microseconds. - `Time` inside `FixedUpdate` now reflects fixed timestep time, making systems portable between `Update ` and `FixedUpdate`. - `Time::pause()`, `Time::set_relative_speed()` and related methods must now be called as `Time<Virtual>::pause()` etc. - There is a new `max_delta` setting in `Time<Virtual>` that limits how much the clock can jump by a single update. The default value is 0.25 seconds. - Removed `on_fixed_timer()` condition as `on_timer()` does the right thing inside `FixedUpdate` now. ## Migration Guide - Change all `Res<Time>` instances that access `raw_delta()`, `raw_elapsed()` and related methods to `Res<Time<Real>>` and `delta()`, `elapsed()`, etc. - Change access to `period` from `Res<FixedTime>` to `Res<Time<Fixed>>` and use `delta()`. - The default timestep has been changed from 60 Hz to 64 Hz. If you wish to restore the old behaviour, use `app.insert_resource(Time::<Fixed>::from_hz(60.0))`. - Change `app.insert_resource(FixedTime::new(duration))` to `app.insert_resource(Time::<Fixed>::from_duration(duration))` - Change `app.insert_resource(FixedTime::new_from_secs(secs))` to `app.insert_resource(Time::<Fixed>::from_seconds(secs))` - Change `system.on_fixed_timer(duration)` to `system.on_timer(duration)`. Timers in systems placed in `FixedUpdate` schedule automatically use the fixed time clock. - Change `ResMut<Time>` calls to `pause()`, `is_paused()`, `set_relative_speed()` and related methods to `ResMut<Time<Virtual>>` calls. The API is the same, with the exception that `relative_speed()` will return the actual last ste relative speed, while `effective_relative_speed()` returns 0.0 if the time is paused and corresponds to the speed that was set when the update for the current frame started. ## Todo - [x] Update pull name and description - [x] Top level documentation on usage - [x] Fix examples - [x] Decide on default `max_delta` value - [x] Decide naming of the three clocks: is `Real`, `Virtual`, `Fixed` good? - [x] Decide if the three clock inner structures should be in prelude - [x] Decide on best way to configure values at startup: is manually inserting a new clock instance okay, or should there be config struct separately? - [x] Fix links in docs - [x] Decide what should be public and what not - [x] Decide how `wrap_period` should be handled when it is changed - [x] ~~Add toggles to disable setting the clock as default?~~ No, separate pull if needed. - [x] Add tests - [x] Reformat, ensure adheres to conventions etc. - [x] Build documentation and see that it looks correct ## Contributors Huge thanks to @alice-i-cecile and @maniwani while building this pull.

Fix CI for Rust 1.72 (#9562)
# Objective [Rust 1.72.0](https://blog.rust-lang.org/2023/08/24/Rust-1.72.0.html) is now stable. # Notes - `let-else` formatting has arrived! - I chose to allow `explicit_iter_loop` due to https://github.com/rust-lang/rust-clippy/issues/11074. We didn't hit any of the false positives that prevent compilation, but fixing this did produce a lot of the "symbol soup" mentioned, e.g. `for image in &mut *image_events {`. Happy to undo this if there's consensus the other way. --------- Co-authored-by: François <mockersf@gmail.com> |

bevy_audio: ECS-based API redesign (#8424)
# Objective Improve the `bevy_audio` API to make it more user-friendly and ECS-idiomatic. This PR is a first-pass at addressing some of the most obvious (to me) problems. In the interest of keeping the scope small, further improvements can be done in future PRs. The current `bevy_audio` API is very clunky to work with, due to how it (ab)uses bevy assets to represent audio sinks. The user needs to write a lot of boilerplate (accessing `Res<Assets<AudioSink>>`) and deal with a lot of cognitive overhead (worry about strong vs. weak handles, etc.) in order to control audio playback. Audio playback is initiated via a centralized `Audio` resource, which makes it difficult to keep track of many different sounds playing in a typical game. Further, everything carries a generic type parameter for the sound source type, making it difficult to mix custom sound sources (such as procedurally generated audio or unofficial formats) with regular audio assets. Let's fix these issues. ## Solution Refactor `bevy_audio` to a more idiomatic ECS API. Remove the `Audio` resource. Do everything via entities and components instead. Audio playback data is now stored in components: - `PlaybackSettings`, `SpatialSettings`, `Handle<AudioSource>` are now components. The user inserts them to tell Bevy to play a sound and configure the initial playback parameters. - `AudioSink`, `SpatialAudioSink` are now components instead of special magical "asset" types. They are inserted by Bevy when it actually begins playing the sound, and can be queried for by the user in order to control the sound during playback. Bundles: `AudioBundle` and `SpatialAudioBundle` are available to make it easy for users to play sounds. Spawn an entity with one of these bundles (or insert them to a complex entity alongside other stuff) to play a sound. Each entity represents a sound to be played. There is also a new "auto-despawn" feature (activated using `PlaybackSettings`), which, if enabled, tells Bevy to despawn entities when the sink playback finishes. This allows for "fire-and-forget" sound playback. Users can simply spawn entities whenever they want to play sounds and not have to worry about leaking memory. ## Unsolved Questions I think the current design is *fine*. I'd be happy for it to be merged. It has some possibly-surprising usability pitfalls, but I think it is still much better than the old `bevy_audio`. Here are some discussion questions for things that we could further improve. I'm undecided on these questions, which is why I didn't implement them. We should decide which of these should be addressed in this PR, and what should be left for future PRs. Or if they should be addressed at all. ### What happens when sounds start playing? Currently, the audio sink components are inserted and the bundle components are kept. Should Bevy remove the bundle components? Something else? The current design allows an entity to be reused for playing the same sound with the same parameters repeatedly. This is a niche use case I'd like to be supported, but if we have to give it up for a simpler design, I'd be fine with that. ### What happens if users remove any of the components themselves? As described above, currently, entities can be reused. Removing the audio sink causes it to be "detached" (I kept the old `Drop` impl), so the sound keeps playing. However, if the audio bundle components are not removed, Bevy will detect this entity as a "queued" sound entity again (has the bundle compoenents, without a sink component), just like before playing the sound the first time, and start playing the sound again. This behavior might be surprising? Should we do something different? ### Should mutations to `PlaybackSettings` be applied to the audio sink? We currently do not do that. `PlaybackSettings` is just for the initial settings when the sound starts playing. This is clearly documented. Do we want to keep this behavior, or do we want to allow users to use `PlaybackSettings` instead of `AudioSink`/`SpatialAudioSink` to control sounds during playback too? I think I prefer for them to be kept separate. It is not a bad mental model once you understand it, and it is documented. ### Should `AudioSink` and `SpatialAudioSink` be unified into a single component type? They provide a similar API (via the `AudioSinkPlayback` trait) and it might be annoying for users to have to deal with both of them. The unification could be done using an enum that is matched on internally by the methods. Spatial audio has extra features, so this might make it harder to access. I think we shouldn't. ### Automatic synchronization of spatial sound properties from Transforms? Should Bevy automatically apply changes to Transforms to spatial audio entities? How do we distinguish between listener and emitter? Which one does the transform represent? Where should the other one come from? Alternatively, leave this problem for now, and address it in a future PR. Or do nothing, and let users deal with it, as shown in the `spatial_audio_2d` and `spatial_audio_3d` examples. --- ## Changelog Added: - `AudioBundle`/`SpatialAudioBundle`, add them to entities to play sounds. Removed: - The `Audio` resource. - `AudioOutput` is no longer `pub`. Changed: - `AudioSink`, `SpatialAudioSink` are now components instead of assets. ## Migration Guide // TODO: write a more detailed migration guide, after the "unsolved questions" are answered and this PR is finalized. Before: ```rust /// Need to store handles somewhere #[derive(Resource)] struct MyMusic { sink: Handle<AudioSink>, } fn play_music( asset_server: Res<AssetServer>, audio: Res<Audio>, audio_sinks: Res<Assets<AudioSink>>, mut commands: Commands, ) { let weak_handle = audio.play_with_settings( asset_server.load("music.ogg"), PlaybackSettings::LOOP.with_volume(0.5), ); // upgrade to strong handle and store it commands.insert_resource(MyMusic { sink: audio_sinks.get_handle(weak_handle), }); } fn toggle_pause_music( audio_sinks: Res<Assets<AudioSink>>, mymusic: Option<Res<MyMusic>>, ) { if let Some(mymusic) = &mymusic { if let Some(sink) = audio_sinks.get(&mymusic.sink) { sink.toggle(); } } } ``` Now: ```rust /// Marker component for our music entity #[derive(Component)] struct MyMusic; fn play_music( mut commands: Commands, asset_server: Res<AssetServer>, ) { commands.spawn(( AudioBundle::from_audio_source(asset_server.load("music.ogg")) .with_settings(PlaybackSettings::LOOP.with_volume(0.5)), MyMusic, )); } fn toggle_pause_music( // `AudioSink` will be inserted by Bevy when the audio starts playing query_music: Query<&AudioSink, With<MyMusic>>, ) { if let Ok(sink) = query.get_single() { sink.toggle(); } } ``` |

Require #[derive(Event)] on all Events (#7086)
# Objective Be consistent with `Resource`s and `Components` and have `Event` types be more self-documenting. Although not susceptible to accidentally using a function instead of a value due to `Event`s only being initialized by their type, much of the same reasoning for removing the blanket impl on `Resource` also applies here. * Not immediately obvious if a type is intended to be an event * Prevent invisible conflicts if the same third-party or primitive types are used as events * Allows for further extensions (e.g. opt-in warning for missed events) ## Solution Remove the blanket impl for the `Event` trait. Add a derive macro for it. --- ## Changelog - `Event` is no longer implemented for all applicable types. Add the `#[derive(Event)]` macro for events. ## Migration Guide * Add the `#[derive(Event)]` macro for events. Third-party types used as events should be wrapped in a newtype. |

Support system.in_schedule() and system.on_startup() (#7790)
# 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 |

Migrate engine to Schedule v3 (#7267)
Huge thanks to @maniwani, @devil-ira, @hymm, @cart, @superdump and @jakobhellermann for the help with this PR. # Objective - Followup #6587. - Minimal integration for the Stageless Scheduling RFC: https://github.com/bevyengine/rfcs/pull/45 ## Solution - [x] Remove old scheduling module - [x] Migrate new methods to no longer use extension methods - [x] Fix compiler errors - [x] Fix benchmarks - [x] Fix examples - [x] Fix docs - [x] Fix tests ## Changelog ### Added - a large number of methods on `App` to work with schedules ergonomically - the `CoreSchedule` enum - `App::add_extract_system` via the `RenderingAppExtension` trait extension method - the private `prepare_view_uniforms` system now has a public system set for scheduling purposes, called `ViewSet::PrepareUniforms` ### Removed - stages, and all code that mentions stages - states have been dramatically simplified, and no longer use a stack - `RunCriteriaLabel` - `AsSystemLabel` trait - `on_hierarchy_reports_enabled` run criteria (now just uses an ad hoc resource checking run condition) - systems in `RenderSet/Stage::Extract` no longer warn when they do not read data from the main world - `RunCriteriaLabel` - `transform_propagate_system_set`: this was a nonstandard pattern that didn't actually provide enough control. The systems are already `pub`: the docs have been updated to ensure that the third-party usage is clear. ### Changed - `System::default_labels` is now `System::default_system_sets`. - `App::add_default_labels` is now `App::add_default_sets` - `CoreStage` and `StartupStage` enums are now `CoreSet` and `StartupSet` - `App::add_system_set` was renamed to `App::add_systems` - The `StartupSchedule` label is now defined as part of the `CoreSchedules` enum - `.label(SystemLabel)` is now referred to as `.in_set(SystemSet)` - `SystemLabel` trait was replaced by `SystemSet` - `SystemTypeIdLabel<T>` was replaced by `SystemSetType<T>` - The `ReportHierarchyIssue` resource now has a public constructor (`new`), and implements `PartialEq` - Fixed time steps now use a schedule (`CoreSchedule::FixedTimeStep`) rather than a run criteria. - Adding rendering extraction systems now panics rather than silently failing if no subapp with the `RenderApp` label is found. - the `calculate_bounds` system, with the `CalculateBounds` label, is now in `CoreSet::Update`, rather than in `CoreSet::PostUpdate` before commands are applied. - `SceneSpawnerSystem` now runs under `CoreSet::Update`, rather than `CoreStage::PreUpdate.at_end()`. - `bevy_pbr::add_clusters` is no longer an exclusive system - the top level `bevy_ecs::schedule` module was replaced with `bevy_ecs::scheduling` - `tick_global_task_pools_on_main_thread` is no longer run as an exclusive system. Instead, it has been replaced by `tick_global_task_pools`, which uses a `NonSend` resource to force running on the main thread. ## Migration Guide - Calls to `.label(MyLabel)` should be replaced with `.in_set(MySet)` - Stages have been removed. Replace these with system sets, and then add command flushes using the `apply_system_buffers` exclusive system where needed. - The `CoreStage`, `StartupStage, `RenderStage` and `AssetStage` enums have been replaced with `CoreSet`, `StartupSet, `RenderSet` and `AssetSet`. The same scheduling guarantees have been preserved. - Systems are no longer added to `CoreSet::Update` by default. Add systems manually if this behavior is needed, although you should consider adding your game logic systems to `CoreSchedule::FixedTimestep` instead for more reliable framerate-independent behavior. - Similarly, startup systems are no longer part of `StartupSet::Startup` by default. In most cases, this won't matter to you. - For example, `add_system_to_stage(CoreStage::PostUpdate, my_system)` should be replaced with - `add_system(my_system.in_set(CoreSet::PostUpdate)` - When testing systems or otherwise running them in a headless fashion, simply construct and run a schedule using `Schedule::new()` and `World::run_schedule` rather than constructing stages - Run criteria have been renamed to run conditions. These can now be combined with each other and with states. - Looping run criteria and state stacks have been removed. Use an exclusive system that runs a schedule if you need this level of control over system control flow. - For app-level control flow over which schedules get run when (such as for rollback networking), create your own schedule and insert it under the `CoreSchedule::Outer` label. - Fixed timesteps are now evaluated in a schedule, rather than controlled via run criteria. The `run_fixed_timestep` system runs this schedule between `CoreSet::First` and `CoreSet::PreUpdate` by default. - Command flush points introduced by `AssetStage` have been removed. If you were relying on these, add them back manually. - Adding extract systems is now typically done directly on the main app. Make sure the `RenderingAppExtension` trait is in scope, then call `app.add_extract_system(my_system)`. - the `calculate_bounds` system, with the `CalculateBounds` label, is now in `CoreSet::Update`, rather than in `CoreSet::PostUpdate` before commands are applied. You may need to order your movement systems to occur before this system in order to avoid system order ambiguities in culling behavior. - the `RenderLabel` `AppLabel` was renamed to `RenderApp` for clarity - `App::add_state` now takes 0 arguments: the starting state is set based on the `Default` impl. - Instead of creating `SystemSet` containers for systems that run in stages, simply use `.on_enter::<State::Variant>()` or its `on_exit` or `on_update` siblings. - `SystemLabel` derives should be replaced with `SystemSet`. You will also need to add the `Debug`, `PartialEq`, `Eq`, and `Hash` traits to satisfy the new trait bounds. - `with_run_criteria` has been renamed to `run_if`. Run criteria have been renamed to run conditions for clarity, and should now simply return a bool. - States have been dramatically simplified: there is no longer a "state stack". To queue a transition to the next state, call `NextState::set` ## TODO - [x] remove dead methods on App and World - [x] add `App::add_system_to_schedule` and `App::add_systems_to_schedule` - [x] avoid adding the default system set at inappropriate times - [x] remove any accidental cycles in the default plugins schedule - [x] migrate benchmarks - [x] expose explicit labels for the built-in command flush points - [x] migrate engine code - [x] remove all mentions of stages from the docs - [x] verify docs for States - [x] fix uses of exclusive systems that use .end / .at_start / .before_commands - [x] migrate RenderStage and AssetStage - [x] migrate examples - [x] ensure that transform propagation is exported in a sufficiently public way (the systems are already pub) - [x] ensure that on_enter schedules are run at least once before the main app - [x] re-enable opt-in to execution order ambiguities - [x] revert change to `update_bounds` to ensure it runs in `PostUpdate` - [x] test all examples - [x] unbreak directional lights - [x] unbreak shadows (see 3d_scene, 3d_shape, lighting, transparaency_3d examples) - [x] game menu example shows loading screen and menu simultaneously - [x] display settings menu is a blank screen - [x] `without_winit` example panics - [x] ensure all tests pass - [x] SubApp doc test fails - [x] runs_spawn_local tasks fails - [x] [Fix panic_when_hierachy_cycle test hanging](https://github.com/alice-i-cecile/bevy/pull/120) ## Points of Difficulty and Controversy **Reviewers, please give feedback on these and look closely** 1. Default sets, from the RFC, have been removed. These added a tremendous amount of implicit complexity and result in hard to debug scheduling errors. They're going to be tackled in the form of "base sets" by @cart in a followup. 2. The outer schedule controls which schedule is run when `App::update` is called. 3. I implemented `Label for `Box<dyn Label>` for our label types. This enables us to store schedule labels in concrete form, and then later run them. I ran into the same set of problems when working with one-shot systems. We've previously investigated this pattern in depth, and it does not appear to lead to extra indirection with nested boxes. 4. `SubApp::update` simply runs the default schedule once. This sucks, but this whole API is incomplete and this was the minimal changeset. 5. `time_system` and `tick_global_task_pools_on_main_thread` no longer use exclusive systems to attempt to force scheduling order 6. Implemetnation strategy for fixed timesteps 7. `AssetStage` was migrated to `AssetSet` without reintroducing command flush points. These did not appear to be used, and it's nice to remove these bottlenecks. 8. Migration of `bevy_render/lib.rs` and pipelined rendering. The logic here is unusually tricky, as we have complex scheduling requirements. ## Future Work (ideally before 0.10) - Rename schedule_v3 module to schedule or scheduling - Add a derive macro to states, and likely a `EnumIter` trait of some form - Figure out what exactly to do with the "systems added should basically work by default" problem - Improve ergonomics for working with fixed timesteps and states - Polish FixedTime API to match Time - Rebase and merge #7415 - Resolve all internal ambiguities (blocked on better tools, especially #7442) - Add "base sets" to replace the removed default sets. |

Borrow instead of consuming in EventReader::clear (#6851)
The PR fixes the interface of `EventReader::clear`. Currently, the method consumes the reader, which makes it unusable. ## Changelog - `EventReader::clear` now takes a mutable reference instead of consuming the event reader. ## Migration Guide `EventReader::clear` now takes a mutable reference instead of consuming the event reader. This means that `clear` now needs explicit mutable access to the reader variable, which previously could have been omitted in some cases: ```rust // Old (0.9) fn clear_events(reader: EventReader<SomeEvent>) { reader.clear(); } // New (0.10) fn clear_events(mut reader: EventReader<SomeEvent>) { reader.clear(); } ``` Co-authored-by: Carter Anderson <mcanders1@gmail.com> |

Spawn now takes a Bundle (#6054)
# Objective Now that we can consolidate Bundles and Components under a single insert (thanks to #2975 and #6039), almost 100% of world spawns now look like `world.spawn().insert((Some, Tuple, Here))`. Spawning an entity without any components is an extremely uncommon pattern, so it makes sense to give spawn the "first class" ergonomic api. This consolidated api should be made consistent across all spawn apis (such as World and Commands). ## Solution All `spawn` apis (`World::spawn`, `Commands:;spawn`, `ChildBuilder::spawn`, and `WorldChildBuilder::spawn`) now accept a bundle as input: ```rust // before: commands .spawn() .insert((A, B, C)); world .spawn() .insert((A, B, C); // after commands.spawn((A, B, C)); world.spawn((A, B, C)); ``` All existing instances of `spawn_bundle` have been deprecated in favor of the new `spawn` api. A new `spawn_empty` has been added, replacing the old `spawn` api. By allowing `world.spawn(some_bundle)` to replace `world.spawn().insert(some_bundle)`, this opened the door to removing the initial entity allocation in the "empty" archetype / table done in `spawn()` (and subsequent move to the actual archetype in `.insert(some_bundle)`). This improves spawn performance by over 10%: ![image](https://user-images.githubusercontent.com/2694663/191627587-4ab2f949-4ccd-4231-80eb-80dd4d9ad6b9.png) To take this measurement, I added a new `world_spawn` benchmark. Unfortunately, optimizing `Commands::spawn` is slightly less trivial, as Commands expose the Entity id of spawned entities prior to actually spawning. Doing the optimization would (naively) require assurances that the `spawn(some_bundle)` command is applied before all other commands involving the entity (which would not necessarily be true, if memory serves). Optimizing `Commands::spawn` this way does feel possible, but it will require careful thought (and maybe some additional checks), which deserves its own PR. For now, it has the same performance characteristics of the current `Commands::spawn_bundle` on main. **Note that 99% of this PR is simple renames and refactors. The only code that needs careful scrutiny is the new `World::spawn()` impl, which is relatively straightforward, but it has some new unsafe code (which re-uses battle tested BundlerSpawner code path).** --- ## Changelog - All `spawn` apis (`World::spawn`, `Commands:;spawn`, `ChildBuilder::spawn`, and `WorldChildBuilder::spawn`) now accept a bundle as input - All instances of `spawn_bundle` have been deprecated in favor of the new `spawn` api - World and Commands now have `spawn_empty()`, which is equivalent to the old `spawn()` behavior. ## Migration Guide ```rust // Old (0.8): commands .spawn() .insert_bundle((A, B, C)); // New (0.9) commands.spawn((A, B, C)); // Old (0.8): commands.spawn_bundle((A, B, C)); // New (0.9) commands.spawn((A, B, C)); // Old (0.8): let entity = commands.spawn().id(); // New (0.9) let entity = commands.spawn_empty().id(); // Old (0.8) let entity = world.spawn().id(); // New (0.9) let entity = world.spawn_empty(); ``` |

Accept Bundles for insert and remove. Deprecate insert/remove_bundle (#6039)
# Objective Take advantage of the "impl Bundle for Component" changes in #2975 / add the follow up changes discussed there. ## Solution - Change `insert` and `remove` to accept a Bundle instead of a Component (for both Commands and World) - Deprecate `insert_bundle`, `remove_bundle`, and `remove_bundle_intersection` - Add `remove_intersection` --- ## Changelog - Change `insert` and `remove` now accept a Bundle instead of a Component (for both Commands and World) - `insert_bundle` and `remove_bundle` are deprecated ## Migration Guide Replace `insert_bundle` with `insert`: ```rust // Old (0.8) commands.spawn().insert_bundle(SomeBundle::default()); // New (0.9) commands.spawn().insert(SomeBundle::default()); ``` Replace `remove_bundle` with `remove`: ```rust // Old (0.8) commands.entity(some_entity).remove_bundle::<SomeBundle>(); // New (0.9) commands.entity(some_entity).remove::<SomeBundle>(); ``` Replace `remove_bundle_intersection` with `remove_intersection`: ```rust // Old (0.8) world.entity_mut(some_entity).remove_bundle_intersection::<SomeBundle>(); // New (0.9) world.entity_mut(some_entity).remove_intersection::<SomeBundle>(); ``` Consider consolidating as many operations as possible to improve ergonomics and cut down on archetype moves: ```rust // Old (0.8) commands.spawn() .insert_bundle(SomeBundle::default()) .insert(SomeComponent); // New (0.9) - Option 1 commands.spawn().insert(( SomeBundle::default(), SomeComponent, )) // New (0.9) - Option 2 commands.spawn_bundle(( SomeBundle::default(), SomeComponent, )) ``` ## Next Steps Consider changing `spawn` to accept a bundle and deprecate `spawn_bundle`. |

Implement Bundle for Component . Use Bundle tuples for insertion (#2975)
@BoxyUwU this is your fault. Also cart didn't arrive in time to tell us not to do this. # Objective - Fix #2974 ## Solution - The first commit just does the actual change - Follow up commits do steps to prove that this method works to unify as required, but this does not remove `insert_bundle`. ## Changelog ### Changed Nested bundles now collapse automatically, and every `Component` now implements `Bundle`. This means that you can combine bundles and components arbitrarily, for example: ```rust // before: .insert(A).insert_bundle(MyBBundle{..}) // after: .insert_bundle((A, MyBBundle {..})) ``` Note that there will be a follow up PR that removes the current `insert` impl and renames `insert_bundle` to `insert`. ### Removed The `bundle` attribute in `derive(Bundle)`. ## Migration guide In `derive(Bundle)`, the `bundle` attribute has been removed. Nested bundles are not collapsed automatically. You should remove `#[bundle]` attributes. Co-authored-by: Carter Anderson <mcanders1@gmail.com> |

# Objective - Replace the square with a circle in the breakout example. - Fixes #4324, adopted from #4682 by @shaderduck. ## Solution - Uses the Mesh2D APIs to draw a circle. The collision still uses the AABB algorithm, but it seems to be working fine, and I haven't seen any odd looking cases. |

Make Resource trait opt-in, requiring #[derive(Resource)] V2 (#5577)
*This PR description is an edited copy of #5007, written by @alice-i-cecile.* # Objective Follow-up to https://github.com/bevyengine/bevy/pull/2254. The `Resource` trait currently has a blanket implementation for all types that meet its bounds. While ergonomic, this results in several drawbacks: * it is possible to make confusing, silent mistakes such as inserting a function pointer (Foo) rather than a value (Foo::Bar) as a resource * it is challenging to discover if a type is intended to be used as a resource * we cannot later add customization options (see the [RFC](https://github.com/bevyengine/rfcs/blob/main/rfcs/27-derive-component.md) for the equivalent choice for Component). * dependencies can use the same Rust type as a resource in invisibly conflicting ways * raw Rust types used as resources cannot preserve privacy appropriately, as anyone able to access that type can read and write to internal values * we cannot capture a definitive list of possible resources to display to users in an editor ## Notes to reviewers * Review this commit-by-commit; there's effectively no back-tracking and there's a lot of churn in some of these commits. *ira: My commits are not as well organized :')* * I've relaxed the bound on Local to Send + Sync + 'static: I don't think these concerns apply there, so this can keep things simple. Storing e.g. a u32 in a Local is fine, because there's a variable name attached explaining what it does. * I think this is a bad place for the Resource trait to live, but I've left it in place to make reviewing easier. IMO that's best tackled with https://github.com/bevyengine/bevy/issues/4981. ## Changelog `Resource` is no longer automatically implemented for all matching types. Instead, use the new `#[derive(Resource)]` macro. ## Migration Guide Add `#[derive(Resource)]` to all types you are using as a resource. If you are using a third party type as a resource, wrap it in a tuple struct to bypass orphan rules. Consider deriving `Deref` and `DerefMut` to improve ergonomics. `ClearColor` no longer implements `Component`. Using `ClearColor` as a component in 0.8 did nothing. Use the `ClearColorConfig` in the `Camera3d` and `Camera2d` components instead.

Improve ergonomics and reduce boilerplate around creating text elements. (#5343)
# Objective
Creating UI elements is very boilerplate-y with lots of indentation.
This PR aims to reduce boilerplate around creating text elements.
## Changelog
* Renamed `Text::with_section` to `from_section`.
It no longer takes a `TextAlignment` as argument, as the vast majority of cases left it `Default::default()`.
* Added `Text::from_sections` which creates a `Text` from a list of `TextSections`.
Reduces line-count and reduces indentation by one level.
* Added `Text::with_alignment`.
A builder style method for setting the `TextAlignment` of a `Text`.
* Added `TextSection::new`.
Does not reduce line count, but reduces character count and made it easier to read. No more `.to_string()` calls!
* Added `TextSection::from_style` which creates an empty `TextSection` with a style.
No more empty strings! Reduces indentation.
* Added `TextAlignment::CENTER` and friends.
* Added methods to `TextBundle`. `from_section`, `from_sections`, `with_text_alignment` and `with_style`.
## Note for reviewers.
Because of the nature of these changes I recommend setting diff view to 'split'.
~~Look for the book icon~~ cog in the top-left of the Files changed tab.
Have fun reviewing ❤️
<sup> >:D </sup>
## Migration Guide
`Text::with_section` was renamed to `from_section` and no longer takes a `TextAlignment` as argument.
Use `with_alignment` to set the alignment instead.

Update codebase to use IntoIterator where possible. (#5269)
Remove unnecessary calls to `iter()`/`iter_mut()`. Mainly updates the use of queries in our code, docs, and examples. ```rust // From for _ in list.iter() { for _ in list.iter_mut() { // To for _ in &list { for _ in &mut list { ``` We already enable the pedantic lint [clippy::explicit_iter_loop](https://rust-lang.github.io/rust-clippy/stable/) inside of Bevy. However, this only warns for a few known types from the standard library. ## Note for reviewers As you can see the additions and deletions are exactly equal. Maybe give it a quick skim to check I didn't sneak in a crypto miner, but you don't have to torture yourself by reading every line. I already experienced enough pain making this PR :) Co-authored-by: devil-ira <justthecooldude@gmail.com> |

Updated glam to 0.21 . (#5142)
Removed `const_vec2`/`const_vec3` and replaced with equivalent `.from_array`. # Objective Fixes #5112 ## Solution - `encase` needs to update to `glam` as well. See teoxoy/encase#4 on progress on that. - `hexasphere` also needs to be updated, see OptimisticPeach/hexasphere#12. |

Camera Driven Rendering (#4745)
This adds "high level camera driven rendering" to Bevy. The goal is to give users more control over what gets rendered (and where) without needing to deal with render logic. This will make scenarios like "render to texture", "multiple windows", "split screen", "2d on 3d", "3d on 2d", "pass layering", and more significantly easier. Here is an [example of a 2d render sandwiched between two 3d renders (each from a different perspective)](https://gist.github.com/cart/4fe56874b2e53bc5594a182fc76f4915): ![image](https://user-images.githubusercontent.com/2694663/168411086-af13dec8-0093-4a84-bdd4-d4362d850ffa.png) Users can now spawn a camera, point it at a RenderTarget (a texture or a window), and it will "just work". Rendering to a second window is as simple as spawning a second camera and assigning it to a specific window id: ```rust // main camera (main window) commands.spawn_bundle(Camera2dBundle::default()); // second camera (other window) commands.spawn_bundle(Camera2dBundle { camera: Camera { target: RenderTarget::Window(window_id), ..default() }, ..default() }); ``` Rendering to a texture is as simple as pointing the camera at a texture: ```rust commands.spawn_bundle(Camera2dBundle { camera: Camera { target: RenderTarget::Texture(image_handle), ..default() }, ..default() }); ``` Cameras now have a "render priority", which controls the order they are drawn in. If you want to use a camera's output texture as a texture in the main pass, just set the priority to a number lower than the main pass camera (which defaults to `0`). ```rust // main pass camera with a default priority of 0 commands.spawn_bundle(Camera2dBundle::default()); commands.spawn_bundle(Camera2dBundle { camera: Camera { target: RenderTarget::Texture(image_handle.clone()), priority: -1, ..default() }, ..default() }); commands.spawn_bundle(SpriteBundle { texture: image_handle, ..default() }) ``` Priority can also be used to layer to cameras on top of each other for the same RenderTarget. This is what "2d on top of 3d" looks like in the new system: ```rust commands.spawn_bundle(Camera3dBundle::default()); commands.spawn_bundle(Camera2dBundle { camera: Camera { // this will render 2d entities "on top" of the default 3d camera's render priority: 1, ..default() }, ..default() }); ``` There is no longer the concept of a global "active camera". Resources like `ActiveCamera<Camera2d>` and `ActiveCamera<Camera3d>` have been replaced with the camera-specific `Camera::is_active` field. This does put the onus on users to manage which cameras should be active. Cameras are now assigned a single render graph as an "entry point", which is configured on each camera entity using the new `CameraRenderGraph` component. The old `PerspectiveCameraBundle` and `OrthographicCameraBundle` (generic on camera marker components like Camera2d and Camera3d) have been replaced by `Camera3dBundle` and `Camera2dBundle`, which set 3d and 2d default values for the `CameraRenderGraph` and projections. ```rust // old 3d perspective camera commands.spawn_bundle(PerspectiveCameraBundle::default()) // new 3d perspective camera commands.spawn_bundle(Camera3dBundle::default()) ``` ```rust // old 2d orthographic camera commands.spawn_bundle(OrthographicCameraBundle::new_2d()) // new 2d orthographic camera commands.spawn_bundle(Camera2dBundle::default()) ``` ```rust // old 3d orthographic camera commands.spawn_bundle(OrthographicCameraBundle::new_3d()) // new 3d orthographic camera commands.spawn_bundle(Camera3dBundle { projection: OrthographicProjection { scale: 3.0, scaling_mode: ScalingMode::FixedVertical, ..default() }.into(), ..default() }) ``` Note that `Camera3dBundle` now uses a new `Projection` enum instead of hard coding the projection into the type. There are a number of motivators for this change: the render graph is now a part of the bundle, the way "generic bundles" work in the rust type system prevents nice `..default()` syntax, and changing projections at runtime is much easier with an enum (ex for editor scenarios). I'm open to discussing this choice, but I'm relatively certain we will all come to the same conclusion here. Camera2dBundle and Camera3dBundle are much clearer than being generic on marker components / using non-default constructors. If you want to run a custom render graph on a camera, just set the `CameraRenderGraph` component: ```rust commands.spawn_bundle(Camera3dBundle { camera_render_graph: CameraRenderGraph::new(some_render_graph_name), ..default() }) ``` Just note that if the graph requires data from specific components to work (such as `Camera3d` config, which is provided in the `Camera3dBundle`), make sure the relevant components have been added. Speaking of using components to configure graphs / passes, there are a number of new configuration options: ```rust commands.spawn_bundle(Camera3dBundle { camera_3d: Camera3d { // overrides the default global clear color clear_color: ClearColorConfig::Custom(Color::RED), ..default() }, ..default() }) commands.spawn_bundle(Camera3dBundle { camera_3d: Camera3d { // disables clearing clear_color: ClearColorConfig::None, ..default() }, ..default() }) ``` Expect to see more of the "graph configuration Components on Cameras" pattern in the future. By popular demand, UI no longer requires a dedicated camera. `UiCameraBundle` has been removed. `Camera2dBundle` and `Camera3dBundle` now both default to rendering UI as part of their own render graphs. To disable UI rendering for a camera, disable it using the CameraUi component: ```rust commands .spawn_bundle(Camera3dBundle::default()) .insert(CameraUi { is_enabled: false, ..default() }) ``` ## Other Changes * The separate clear pass has been removed. We should revisit this for things like sky rendering, but I think this PR should "keep it simple" until we're ready to properly support that (for code complexity and performance reasons). We can come up with the right design for a modular clear pass in a followup pr. * I reorganized bevy_core_pipeline into Core2dPlugin and Core3dPlugin (and core_2d / core_3d modules). Everything is pretty much the same as before, just logically separate. I've moved relevant types (like Camera2d, Camera3d, Camera3dBundle, Camera2dBundle) into their relevant modules, which is what motivated this reorganization. * I adapted the `scene_viewer` example (which relied on the ActiveCameras behavior) to the new system. I also refactored bits and pieces to be a bit simpler. * All of the examples have been ported to the new camera approach. `render_to_texture` and `multiple_windows` are now _much_ simpler. I removed `two_passes` because it is less relevant with the new approach. If someone wants to add a new "layered custom pass with CameraRenderGraph" example, that might fill a similar niche. But I don't feel much pressure to add that in this pr. * Cameras now have `target_logical_size` and `target_physical_size` fields, which makes finding the size of a camera's render target _much_ simpler. As a result, the `Assets<Image>` and `Windows` parameters were removed from `Camera::world_to_screen`, making that operation much more ergonomic. * Render order ambiguities between cameras with the same target and the same priority now produce a warning. This accomplishes two goals: 1. Now that there is no "global" active camera, by default spawning two cameras will result in two renders (one covering the other). This would be a silent performance killer that would be hard to detect after the fact. By detecting ambiguities, we can provide a helpful warning when this occurs. 2. Render order ambiguities could result in unexpected / unpredictable render results. Resolving them makes sense. ## Follow Up Work * Per-Camera viewports, which will make it possible to render to a smaller area inside of a RenderTarget (great for something like splitscreen) * Camera-specific MSAA config (should use the same "overriding" pattern used for ClearColor) * Graph Based Camera Ordering: priorities are simple, but they make complicated ordering constraints harder to express. We should consider adopting a "graph based" camera ordering model with "before" and "after" relationships to other cameras (or build it "on top" of the priority system). * Consider allowing graphs to run subgraphs from any nest level (aka a global namespace for graphs). Right now the 2d and 3d graphs each need their own UI subgraph, which feels "fine" in the short term. But being able to share subgraphs between other subgraphs seems valuable. * Consider splitting `bevy_core_pipeline` into `bevy_core_2d` and `bevy_core_3d` packages. Theres a shared "clear color" dependency here, which would need a new home. |

Clippy improvements (#4665)
# Objective Follow up to my previous MR #3718 to add new clippy warnings to bevy: - [x] [~~option_if_let_else~~](https://rust-lang.github.io/rust-clippy/master/#option_if_let_else) (reverted) - [x] [redundant_else](https://rust-lang.github.io/rust-clippy/master/#redundant_else) - [x] [match_same_arms](https://rust-lang.github.io/rust-clippy/master/#match_same_arms) - [x] [semicolon_if_nothing_returned](https://rust-lang.github.io/rust-clippy/master/#semicolon_if_nothing_returned) - [x] [explicit_iter_loop](https://rust-lang.github.io/rust-clippy/master/#explicit_iter_loop) - [x] [map_flatten](https://rust-lang.github.io/rust-clippy/master/#map_flatten) There is one commit per clippy warning, and the matching flags are added to the CI execution. To test the CI execution you may run `cargo run -p ci -- clippy` at the root. I choose the add the flags in the `ci` tool crate to avoid having them in every `lib.rs` but I guess it could become an issue with suprise warnings coming up after a commit/push Co-authored-by: Carter Anderson <mcanders1@gmail.com> |

Split time functionality into bevy_time (#4187)
# Objective Reduce the catch-all grab-bag of functionality in bevy_core by minimally splitting off time functionality into bevy_time. Functionality like that provided by #3002 would increase the complexity of bevy_time, so this is a good candidate for pulling into its own unit. A step in addressing #2931 and splitting bevy_core into more specific locations. ## Solution Pull the time module of bevy_core into a new crate, bevy_time. # Migration guide - Time related types (e.g. `Time`, `Timer`, `Stopwatch`, `FixedTimestep`, etc.) should be imported from `bevy::time::*` rather than `bevy::core::*`. - If you were adding `CorePlugin` manually, you'll also want to add `TimePlugin` from `bevy::time`. - The `bevy::core::CorePlugin::Time` system label is replaced with `bevy::time::TimeSystem`.

Doc/module style doc blocks for examples (#4438)
# Objective Provide a starting point for #3951, or a partial solution. Providing a few comment blocks to discuss, and hopefully find better one in the process. ## Solution Since I am pretty new to pretty much anything in this context, I figured I'd just start with a draft for some file level doc blocks. For some of them I found more relevant details (or at least things I considered interessting), for some others there is less. ## Changelog - Moved some existing comments from main() functions in the 2d examples to the file header level - Wrote some more comment blocks for most other 2d examples TODO: - [x] 2d/sprite_sheet, wasnt able to come up with something good yet - [x] all other example groups... Also: Please let me know if the commit style is okay, or to verbose. I could certainly squash these things, or add more details if needed. I also hope its okay to raise this PR this early, with just a few files changed. Took me long enough and I dont wanted to let it go to waste because I lost motivation to do the whole thing. Additionally I am somewhat uncertain over the style and contents of the commets. So let me know what you thing please. |

Add a clear() method to the EventReader that consumes the iterator (#4693)
# Objective - It's pretty common to want to check if an EventReader has received one or multiple events while also needing to consume the iterator to "clear" the EventReader. - The current approach is to do something like `events.iter().count() > 0` or `events.iter().last().is_some()`. It's not immediately obvious that the purpose of that is to consume the events and check if there were any events. My solution doesn't really solve that part, but it encapsulates the pattern. ## Solution - Add a `.clear()` method that consumes the iterator. - It takes the EventReader by value to make sure it isn't used again after it has been called. --- ## Migration Guide Not a breaking change, but if you ever found yourself in a situation where you needed to consume the EventReader and check if there was any events you can now use ```rust fn system(events: EventReader<MyEvent>) { if !events.is_empty { events.clear(); // Process the fact that one or more event was received } } ``` Co-authored-by: Charles <IceSentry@users.noreply.github.com> |

Allow closing windows at runtime (#3575)
# Objective Fixes #3180, builds from https://github.com/bevyengine/bevy/pull/2898 ## Solution Support requesting a window to be closed and closing a window in `bevy_window`, and handle this in `bevy_winit`. This is a stopgap until we move to windows as entites, which I'm sure I'll get around to eventually. ## Changelog ### Added - `Window::close` to allow closing windows. - `WindowClosed` to allow reacting to windows being closed. ### Changed Replaced `bevy::system::exit_on_esc_system` with `bevy:🪟:close_on_esc`. ## Fixed The app no longer exits when any window is closed. This difference is only observable when there are multiple windows. ## Migration Guide `bevy::input::system::exit_on_esc_system` has been removed. Use `bevy:🪟:close_on_esc` instead. `CloseWindow` has been removed. Use `Window::close` instead. The `Close` variant has been added to `WindowCommand`. Handle this by closing the relevant window. |

Move Rect to bevy_ui and rename it to UiRect (#4276)
# Objective - Closes #335. - Related #4285. - Part of the splitting process of #3503. ## Solution - Move `Rect` to `bevy_ui` and rename it to `UiRect`. ## Reasons - `Rect` is only used in `bevy_ui` and therefore calling it `UiRect` makes the intent clearer. - We have two types that are called `Rect` currently and it's missleading (see `bevy_sprite::Rect` and #335). - Discussion in #3503. ## Changelog ### Changed - The `Rect` type got moved from `bevy_math` to `bevy_ui` and renamed to `UiRect`. ## Migration Guide - The `Rect` type got renamed to `UiRect`. To migrate you just have to change every occurrence of `Rect` to `UiRect`. Co-authored-by: KDecay <KDecayMusic@protonmail.com> |

Add simple collision sound to breakout (#4331)
# Objective - Add sound effect to the breakout example ## Solution - Add a collision event and a system that listens to the event and plays a sound I only added a single sound for all collisions for the sake of simplicity, but this could easily be extended to play a different sound depending on the type of entity hit. The sound was generated randomly by using https://sfxr.me https://sfxr.me/#11111GA9soYREjtsWhzjPrpMDEYSjX8Fo1E6PnKhxdw6tu869XW4EAc3nzpKVAYLMzToNcHQtQjeBqjZukqPmMDToGdYQQCWBnC3nEYfp53se5ep9btxRdLK Closes #4326 https://user-images.githubusercontent.com/8348954/160154727-00e30743-3385-4c2f-97f0-1aaaf9a4dcc5.mp4 For some reason the video has a lot of delay in the sound, but when playing it locally there's no delay --- ## Changelog - Added sound to breakout example - Added bevy_audio and vorbis to the feature list ran for examples in CI ## Migration Guide N/A |

Group stress test examples (#4289)
# Objective - Several examples are useful for qualitative tests of Bevy's performance - By contrast, these are less useful for learning material: they are often relatively complex and have large amounts of setup and are performance optimized. ## Solution - Move bevymark, many_sprites and many_cubes into the new stress_tests example folder - Move contributors into the games folder: unlike the remaining examples in the 2d folder, it is not focused on demonstrating a clear feature. |
