Migrate cameras to required components (#15641)
# Objective Yet another PR for migrating stuff to required components. This time, cameras! ## Solution As per the [selected proposal](https://hackmd.io/tsYID4CGRiWxzsgawzxG_g#Combined-Proposal-1-Selected), deprecate `Camera2dBundle` and `Camera3dBundle` in favor of `Camera2d` and `Camera3d`. Adding a `Camera` without `Camera2d` or `Camera3d` now logs a warning, as suggested by Cart [on Discord](https://discord.com/channels/691052431525675048/1264881140007702558/1291506402832945273). I would personally like cameras to work a bit differently and be split into a few more components, to avoid some footguns and confusing semantics, but that is more controversial, and shouldn't block this core migration. ## Testing I ran a few 2D and 3D examples, and tried cameras with and without render graphs. --- ## Migration Guide `Camera2dBundle` and `Camera3dBundle` have been deprecated in favor of `Camera2d` and `Camera3d`. Inserting them will now also insert the other components required by them automatically. |

Fix floating point math (#15239)
# Objective - Fixes #15236 ## Solution - Use bevy_math::ops instead of std floating point operations. ## Testing - Did you test these changes? If so, how? Unit tests and `cargo run -p ci -- test` - How can other people (reviewers) test your changes? Is there anything specific they need to know? Execute `cargo run -p ci -- test` on Windows. - If relevant, what platforms did you test these changes on, and are there any important ones you can't test? Windows ## Migration Guide - Not a breaking change - Projects should use bevy math where applicable --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com> Co-authored-by: IQuick 143 <IQuick143cz@gmail.com> Co-authored-by: Joona Aalto <jondolf.dev@gmail.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(); ``` |

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.

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. |

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%:  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(); ``` |

Very minor doc formatting changes (#5287)
# Objective - Added a bunch of backticks to things that should have them, like equations, abstract variable names, - Changed all small x, y, and z to capitals X, Y, Z. This might be more annoying than helpful; Feel free to refuse this PR. |

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 :)

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):  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. |

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. |

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. |

default() shorthand (#4071)
Adds a `default()` shorthand for `Default::default()` ... because life is too short to constantly type `Default::default()`.
```rust
use bevy::prelude::*;
#[derive(Default)]
struct Foo {
bar: usize,
baz: usize,
}
// Normally you would do this:
let foo = Foo {
bar: 10,
..Default::default()
};
// But now you can do this:
let foo = Foo {
bar: 10,
..default()
};
```
The examples have been adapted to use `..default()`. I've left internal crates as-is for now because they don't pull in the bevy prelude, and the ergonomics of each case should be considered individually.

Simple 2d rotation example (#3065)
# Objective Some new bevy users are unfamiliar with quaternions and have trouble working with rotations in 2D. There has been an [issue](https://github.com/bitshifter/glam-rs/issues/226) raised with glam to add helpers to better support these users, however for now I feel could be better to provide examples of how to do this in Bevy as a starting point for new users. ## Solution I've added a 2d_rotation example which demonstrates 3 different rotation examples to try help get people started: - Rotating and translating a player ship based on keyboard input - An enemy ship type that rotates to face the player ship immediately - An enemy ship type that rotates to face the player at a fixed angular velocity I also have a standalone version of this example here https://github.com/bitshifter/bevy-2d-rotation-example but I think it would be more discoverable if it's included with Bevy. |
