Picking event ordering (#14862) # Objective Correctly order picking events. Resolves https://github.com/bevyengine/bevy/issues/5984. ## Solution Event ordering [very long standing problem](https://github.com/aevyrie/bevy_mod_picking/issues/294) with mod picking, stemming from two related issues. The first problem was that `Pointer<T>` events of different types couldn't be ordered, but we have already gotten around that in the upstream by switching to observers. Since observers run in the order they are triggered, this isn't an issue. The second problem was that the underlying event streams that picking uses to create it's pointer interaction events *also* lacked ordering, and the systems that generated the points couldn't interleave events. This PR fixes that by unifying the event streams and integrating the various interaction systems. The concrete changes are as follows: + `bevy_winit::WinitEvent` has been moved to `bevy_window::WindowEvent`. This provides a unified (and more importantly, *ordered*) input stream for both `bevy_window` and `bevy_input` events. + Replaces `InputMove` and `InputPress` with `PointerInput`, a new unified input event which drives picking and interaction. This event is built to have drop-in forward compatibility with [winit's upcoming pointer abstraction](https://github.com/rust-windowing/winit/pull/3876). I have added code to emulate it using the current winit input abstractions, but this entire thing will be much more robust when it lands. + Rolls `pointer_events` `send_click_and_drag_events` and `send_drag_over_events` into a single system, which operates directly on `PointerEvent` and triggers observers as output. The PR also improves docs and takes the opportunity to refactor/streamline the pointer event dispatch logic. ## Status & Testing This PR is now feature complete and documented. While it is theoretically possible to add unit tests for the ordering, building the picking mocking for that will take a little while. Feedback on the chosen ordering of events is within-scope. ## Migration Guide For users switching from `bevy_mod_picking` to `bevy_picking`: + Instead of adding an `On<T>` component, use `.observe(|trigger: Trigger<T>|)`. You may now apply multiple handlers to the same entity using this command. + Pointer interaction events now have semi-deterministic ordering which (more or less) aligns with the order of the raw input stream. Consult the docs on `bevy_picking::event::pointer_events` for current information. You may need to adjust your event handling logic accordingly. + `PointerCancel` has been replaced with `Pointer<Cancled>`, which now has the semantics of an OS touch pointer cancel event. + `InputMove` and `InputPress` have been merged into `PointerInput`. The use remains exactly the same. + Picking interaction events are now only accessible through observers, and no `EventReader`. This functionality may be re-implemented later. For users of `bevy_winit`: + The event `bevy_winit::WinitEvent` has moved to `bevy_window::WindowEvent`. If this was the only thing you depended on `bevy_winit` for, you should switch your dependency to `bevy_window`. + `bevy_window` now depends on `bevy_input`. The dependencies of `bevy_input` are a subset of the existing dependencies for `bevy_window` so this should be non-breaking.

bevy_reflect: `FromReflect` Ergonomics Implementation (#6056) # Objective **This implementation is based on https://github.com/bevyengine/rfcs/pull/59.** --- Resolves #4597 Full details and motivation can be found in the RFC, but here's a brief summary. `FromReflect` is a very powerful and important trait within the reflection API. It allows Dynamic types (e.g., `DynamicList`, etc.) to be formed into Real ones (e.g., `Vec<i32>`, etc.). This mainly comes into play concerning deserialization, where the reflection deserializers both return a `Box<dyn Reflect>` that almost always contain one of these Dynamic representations of a Real type. To convert this to our Real type, we need to use `FromReflect`. It also sneaks up in other ways. For example, it's a required bound for `T` in `Vec<T>` so that `Vec<T>` as a whole can be made `FromReflect`. It's also required by all fields of an enum as it's used as part of the `Reflect::apply` implementation. So in other words, much like `GetTypeRegistration` and `Typed`, it is very much a core reflection trait. The problem is that it is not currently treated like a core trait and is not automatically derived alongside `Reflect`. This makes using it a bit cumbersome and easy to forget. ## Solution Automatically derive `FromReflect` when deriving `Reflect`. Users can then choose to opt-out if needed using the `#[reflect(from_reflect = false)]` attribute. ```rust #[derive(Reflect)] struct Foo; #[derive(Reflect)] #[reflect(from_reflect = false)] struct Bar; fn test<T: FromReflect>(value: T) {} test(Foo); // <-- OK test(Bar); // <-- Panic! Bar does not implement trait `FromReflect` ``` #### `ReflectFromReflect` This PR also automatically adds the `ReflectFromReflect` (introduced in #6245) registration to the derived `GetTypeRegistration` impl— if the type hasn't opted out of `FromReflect` of course. <details> <summary><h4>Improved Deserialization</h4></summary> > **Warning** > This section includes changes that have since been descoped from this PR. They will likely be implemented again in a followup PR. I am mainly leaving these details in for archival purposes, as well as for reference when implementing this logic again. And since we can do all the above, we might as well improve deserialization. We can now choose to deserialize into a Dynamic type or automatically convert it using `FromReflect` under the hood. `[Un]TypedReflectDeserializer::new` will now perform the conversion and return the `Box`'d Real type. `[Un]TypedReflectDeserializer::new_dynamic` will work like what we have now and simply return the `Box`'d Dynamic type. ```rust // Returns the Real type let reflect_deserializer = UntypedReflectDeserializer::new(&registry); let mut deserializer = ron::de::Deserializer::from_str(input)?; let output: SomeStruct = reflect_deserializer.deserialize(&mut deserializer)?.take()?; // Returns the Dynamic type let reflect_deserializer = UntypedReflectDeserializer::new_dynamic(&registry); let mut deserializer = ron::de::Deserializer::from_str(input)?; let output: DynamicStruct = reflect_deserializer.deserialize(&mut deserializer)?.take()?; ``` </details> --- ## Changelog * `FromReflect` is now automatically derived within the `Reflect` derive macro * This includes auto-registering `ReflectFromReflect` in the derived `GetTypeRegistration` impl * ~~Renamed `TypedReflectDeserializer::new` and `UntypedReflectDeserializer::new` to `TypedReflectDeserializer::new_dynamic` and `UntypedReflectDeserializer::new_dynamic`, respectively~~ **Descoped** * ~~Changed `TypedReflectDeserializer::new` and `UntypedReflectDeserializer::new` to automatically convert the deserialized output using `FromReflect`~~ **Descoped** ## Migration Guide * `FromReflect` is now automatically derived within the `Reflect` derive macro.

Reduce power usage with configurable event loop (#3974) # Objective - Reduce power usage for games when not focused. - Reduce power usage to ~0 when a desktop application is minimized (opt-in). - Reduce power usage when focused, only updating on a `winit` event, or the user sends a redraw request. (opt-in) https://user-images.githubusercontent.com/2632925/156904387-ec47d7de-7f06-4c6f-8aaf-1e952c1153a2.mp4 Note resource usage in the Task Manager in the above video. ## Solution - Added a type `UpdateMode` that allows users to specify how the winit event loop is updated, without exposing winit types. - Added two fields to `WinitConfig`, both with the `UpdateMode` type. One configures how the application updates when focused, and the other configures how the application behaves when it is not focused. Users can modify this resource manually to set the type of event loop control flow they want. - For convenience, two functions were added to `WinitConfig`, that provide reasonable presets: `game()` (default) and `desktop_app()`. - The `game()` preset, which is used by default, is unchanged from current behavior with one exception: when the app is out of focus the app updates at a minimum of 10fps, or every time a winit event is received. This has a huge positive impact on power use and responsiveness on my machine, which will otherwise continue running the app at many hundreds of fps when out of focus or minimized. - The `desktop_app()` preset is fully reactive, only updating when user input (winit event) is supplied or a `RedrawRequest` event is sent. When the app is out of focus, it only updates on `Window` events - i.e. any winit event that directly interacts with the window. What this means in practice is that the app uses *zero* resources when minimized or not interacted with, but still updates fluidly when the app is out of focus and the user mouses over the application. - Added a `RedrawRequest` event so users can force an update even if there are no events. This is useful in an application when you want to, say, run an animation even when the user isn't providing input. - Added an example `low_power` to demonstrate these changes ## Usage Configuring the event loop: ```rs use bevy::winit::{WinitConfig}; // ... .insert_resource(WinitConfig::desktop_app()) // preset // or .insert_resource(WinitConfig::game()) // preset // or .insert_resource(WinitConfig{ .. }) // manual ``` Requesting a redraw: ```rs use bevy::window::RequestRedraw; // ... fn request_redraw(mut event: EventWriter<RequestRedraw>) { event.send(RequestRedraw); } ``` ## Other details - Because we have a single event loop for multiple windows, every time I've mentioned "focused" above, I more precisely mean, "if at least one bevy window is focused". - Due to a platform bug in winit (https://github.com/rust-windowing/winit/issues/1619), we can't simply use `Window::request_redraw()`. As a workaround, this PR will temporarily set the window mode to `Poll` when a redraw is requested. This is then reset to the user's `WinitConfig` setting on the next frame.

bevy_reflect: `FromReflect` Ergonomics Implementation (#6056) # Objective **This implementation is based on https://github.com/bevyengine/rfcs/pull/59.** --- Resolves #4597 Full details and motivation can be found in the RFC, but here's a brief summary. `FromReflect` is a very powerful and important trait within the reflection API. It allows Dynamic types (e.g., `DynamicList`, etc.) to be formed into Real ones (e.g., `Vec<i32>`, etc.). This mainly comes into play concerning deserialization, where the reflection deserializers both return a `Box<dyn Reflect>` that almost always contain one of these Dynamic representations of a Real type. To convert this to our Real type, we need to use `FromReflect`. It also sneaks up in other ways. For example, it's a required bound for `T` in `Vec<T>` so that `Vec<T>` as a whole can be made `FromReflect`. It's also required by all fields of an enum as it's used as part of the `Reflect::apply` implementation. So in other words, much like `GetTypeRegistration` and `Typed`, it is very much a core reflection trait. The problem is that it is not currently treated like a core trait and is not automatically derived alongside `Reflect`. This makes using it a bit cumbersome and easy to forget. ## Solution Automatically derive `FromReflect` when deriving `Reflect`. Users can then choose to opt-out if needed using the `#[reflect(from_reflect = false)]` attribute. ```rust #[derive(Reflect)] struct Foo; #[derive(Reflect)] #[reflect(from_reflect = false)] struct Bar; fn test<T: FromReflect>(value: T) {} test(Foo); // <-- OK test(Bar); // <-- Panic! Bar does not implement trait `FromReflect` ``` #### `ReflectFromReflect` This PR also automatically adds the `ReflectFromReflect` (introduced in #6245) registration to the derived `GetTypeRegistration` impl— if the type hasn't opted out of `FromReflect` of course. <details> <summary><h4>Improved Deserialization</h4></summary> > **Warning** > This section includes changes that have since been descoped from this PR.

Ensure clean exit (#13236) # Objective Fixes two issues related to #13208. First, we ensure render resources for a window are always dropped first to ensure that the `winit::Window` always drops on the main thread when it is removed from `WinitWindows`. Previously, changes in #12978 caused the window to drop in the render world, causing issues. We accomplish this by delaying despawning the window by a frame by inserting a marker component `ClosingWindow` that indicates the window has been requested to close and is in the process of closing. The render world now responds to the equivalent `WindowClosing` event rather than `WindowCloseed` which now fires after the render resources are guarunteed to be cleaned up. Secondly, fixing the above caused (revealed?) that additional events were being delivered to the the event loop handler after exit had already been requested: in my testing `RedrawRequested` and `LoopExiting`. This caused errors to be reported try to send an exit event on the close channel. There are two options here: - Guard the handler so no additional events are delivered once the app is exiting. I ~considered this but worried it might be confusing or bug prone if in the future someone wants to handle `LoopExiting` or some other event to clean-up while exiting.~ We are now taking this approach. - Only send an exit signal if we are not already exiting. ~It doesn't appear to cause any problems to handle the extra events so this seems safer.~ Fixing this also appears to have fixed #13231. Fixes #10260. ## Testing Tested on mac only. --- ## Changelog ### Added - A `WindowClosing` event has been added that indicates the window will be despawned on the next frame. ### Changed - Windows now close a frame after their exit has been requested. ## Migration Guide - Ensure custom exit logic does not rely on the app exiting the same frame as a window is closed.

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::window::close_on_esc; // New: use bevy::dev_tools::close_on_esc; App::new() .add_systems(Update, close_on_esc) // ... .run(); ```

bevy_reflect: `FromReflect` Ergonomics Implementation (#6056) # Objective **This implementation is based on https://github.com/bevyengine/rfcs/pull/59.** --- Resolves #4597 Full details and motivation can be found in the RFC, but here's a brief summary. `FromReflect` is a very powerful and important trait within the reflection API. It allows Dynamic types (e.g., `DynamicList`, etc.) to be formed into Real ones (e.g., `Vec<i32>`, etc.). This mainly comes into play concerning deserialization, where the reflection deserializers both return a `Box<dyn Reflect>` that almost always contain one of these Dynamic representations of a Real type. To convert this to our Real type, we need to use `FromReflect`. It also sneaks up in other ways. For example, it's a required bound for `T` in `Vec<T>` so that `Vec<T>` as a whole can be made `FromReflect`. It's also required by all fields of an enum as it's used as part of the `Reflect::apply` implementation. So in other words, much like `GetTypeRegistration` and `Typed`, it is very much a core reflection trait. The problem is that it is not currently treated like a core trait and is not automatically derived alongside `Reflect`. This makes using it a bit cumbersome and easy to forget. ## Solution Automatically derive `FromReflect` when deriving `Reflect`. Users can then choose to opt-out if needed using the `#[reflect(from_reflect = false)]` attribute. ```rust #[derive(Reflect)] struct Foo; #[derive(Reflect)] #[reflect(from_reflect = false)] struct Bar; fn test<T: FromReflect>(value: T) {} test(Foo); // <-- OK test(Bar); // <-- Panic! Bar does not implement trait `FromReflect` ``` #### `ReflectFromReflect` This PR also automatically adds the `ReflectFromReflect` (introduced in #6245) registration to the derived `GetTypeRegistration` impl— if the type hasn't opted out of `FromReflect` of course. <details> <summary><h4>Improved Deserialization</h4></summary> > **Warning** > This section includes changes that have since been descoped from this PR. They will likely be implemented again in a followup PR. I am mainly leaving these details in for archival purposes, as well as for reference when implementing this logic again. And since we can do all the above, we might as well improve deserialization. We can now choose to deserialize into a Dynamic type or automatically convert it using `FromReflect` under the hood. `[Un]TypedReflectDeserializer::new` will now perform the conversion and return the `Box`'d Real type. `[Un]TypedReflectDeserializer::new_dynamic` will work like what we have now and simply return the `Box`'d Dynamic type. ```rust // Returns the Real type let reflect_deserializer = UntypedReflectDeserializer::new(&registry); let mut deserializer = ron::de::Deserializer::from_str(input)?; let output: SomeStruct = reflect_deserializer.deserialize(&mut deserializer)?.take()?; // Returns the Dynamic type let reflect_deserializer = UntypedReflectDeserializer::new_dynamic(&registry); let mut deserializer = ron::de::Deserializer::from_str(input)?; let output: DynamicStruct = reflect_deserializer.deserialize(&mut deserializer)?.take()?; ``` </details> --- ## Changelog * `FromReflect` is now automatically derived within the `Reflect` derive macro * This includes auto-registering `ReflectFromReflect` in the derived `GetTypeRegistration` impl * ~~Renamed `TypedReflectDeserializer::new` and `UntypedReflectDeserializer::new` to `TypedReflectDeserializer::new_dynamic` and `UntypedReflectDeserializer::new_dynamic`, respectively~~ **Descoped** * ~~Changed `TypedReflectDeserializer::new` and `UntypedReflectDeserializer::new` to automatically convert the deserialized output using `FromReflect`~~ **Descoped** ## Migration Guide * `FromReflect` is now automatically derived within the `Reflect` derive macro. Items with both derives will need to remove the `FromReflect` one. ```rust // OLD #[derive(Reflect, FromReflect)] struct Foo; // NEW #[derive(Reflect)] struct Foo; ``` If using a manual implementation of `FromReflect` and the `Reflect` derive, users will need to opt-out of the automatic implementation. ```rust // OLD #[derive(Reflect)] struct Foo; impl FromReflect for Foo {/* ... */} // NEW #[derive(Reflect)] #[reflect(from_reflect = false)] struct Foo; impl FromReflect for Foo {/* ... */} ``` <details> <summary><h4>Removed Migrations</h4></summary> > **Warning** > This section includes changes that have since been descoped from this PR.

bevy_reflect: `FromReflect` Ergonomics Implementation (#6056) # Objective **This implementation is based on https://github.com/bevyengine/rfcs/pull/59.** --- Resolves #4597 Full details and motivation can be found in the RFC, but here's a brief summary. `FromReflect` is a very powerful and important trait within the reflection API. It allows Dynamic types (e.g., `DynamicList`, etc.) to be formed into Real ones (e.g., `Vec<i32>`, etc.). This mainly comes into play concerning deserialization, where the reflection deserializers both return a `Box<dyn Reflect>` that almost always contain one of these Dynamic representations of a Real type. To convert this to our Real type, we need to use `FromReflect`. It also sneaks up in other ways. For example, it's a required bound for `T` in `Vec<T>` so that `Vec<T>` as a whole can be made `FromReflect`. It's also required by all fields of an enum as it's used as part of the `Reflect::apply` implementation. So in other words, much like `GetTypeRegistration` and `Typed`, it is very much a core reflection trait. The problem is that it is not currently treated like a core trait and is not automatically derived alongside `Reflect`. This makes using it a bit cumbersome and easy to forget. ## Solution Automatically derive `FromReflect` when deriving `Reflect`. Users can then choose to opt-out if needed using the `#[reflect(from_reflect = false)]` attribute. ```rust #[derive(Reflect)] struct Foo; #[derive(Reflect)] #[reflect(from_reflect = false)] struct Bar; fn test<T: FromReflect>(value: T) {} test(Foo); // <-- OK test(Bar); // <-- Panic! Bar does not implement trait `FromReflect` ``` #### `ReflectFromReflect` This PR also automatically adds the `ReflectFromReflect` (introduced in #6245) registration to the derived `GetTypeRegistration` impl— if the type hasn't opted out of `FromReflect` of course. <details> <summary><h4>Improved Deserialization</h4></summary> > **Warning** > This section includes changes that have since been descoped from this PR. They will likely be implemented again in a followup PR. I am mainly leaving these details in for archival purposes, as well as for reference when implementing this logic again. And since we can do all the above, we might as well improve deserialization. We can now choose to deserialize into a Dynamic type or automatically convert it using `FromReflect` under the hood. `[Un]TypedReflectDeserializer::new` will now perform the conversion and return the `Box`'d Real type. `[Un]TypedReflectDeserializer::new_dynamic` will work like what we have now and simply return the `Box`'d Dynamic type. ```rust // Returns the Real type let reflect_deserializer = UntypedReflectDeserializer::new(&registry); let mut deserializer = ron::de::Deserializer::from_str(input)?; let output: SomeStruct = reflect_deserializer.deserialize(&mut deserializer)?.take()?; // Returns the Dynamic type let reflect_deserializer = UntypedReflectDeserializer::new_dynamic(&registry); let mut deserializer = ron::de::Deserializer::from_str(input)?; let output: DynamicStruct = reflect_deserializer.deserialize(&mut deserializer)?.take()?; ``` </details> --- ## Changelog * `FromReflect` is now automatically derived within the `Reflect` derive macro * This includes auto-registering `ReflectFromReflect` in the derived `GetTypeRegistration` impl * ~~Renamed `TypedReflectDeserializer::new` and `UntypedReflectDeserializer::new` to `TypedReflectDeserializer::new_dynamic` and `UntypedReflectDeserializer::new_dynamic`, respectively~~ **Descoped** * ~~Changed `TypedReflectDeserializer::new` and `UntypedReflectDeserializer::new` to automatically convert the deserialized output using `FromReflect`~~ **Descoped** ## Migration Guide * `FromReflect` is now automatically derived within the `Reflect` derive macro.

Changed spelling linebreak_behaviour to linebreak_behavior (#8285) # Objective In the [`Text`](https://github.com/bevyengine/bevy/blob/3442a13d2cb4b2d77c9f7bf8b6dad25742bd21d7/crates/bevy_text/src/text.rs#L18) struct the field is named: `linebreak_behaviour`, the British spelling of _behavior_. **Update**, also found: - `FileDragAndDrop::HoveredFileCancelled` - `TouchPhase::Cancelled` - `Touches.just_cancelled` The majority of all spelling is in the US but when you have a lot of contributors across the world, sometimes spelling differences can pop up in APIs such as in this case. For consistency, I think it would be worth a while to ensure that the API is persistent. Some examples: `from_reflect.rs` has `DefaultBehavior` TextStyle has `color` and uses the `Color` struct. In `bevy_input/src/Touch.rs` `TouchPhase::Cancelled` and _canceled_ are used interchangeably in the documentation I've found that there is also the same type of discrepancies in the documentation, though this is a low priority but is worth checking. **Update**: I've now checked the documentation (See #8291) ## Solution I've only renamed the inconsistencies that have breaking changes and documentation pertaining to them. The rest of the documentation will be changed via #8291. Do note that the winit API is written with UK spelling, thus this may be a cause for confusion: `winit::event::TouchPhase::Cancelled => TouchPhase::Canceled` `winit::event::WindowEvent::HoveredFileCancelled` -> Related to `FileDragAndDrop::HoveredFileCanceled` But I'm hoping to maybe outline other spelling inconsistencies in the API, and maybe an addition to the contribution guide. --- ## Changelog - `Text` field `linebreak_behaviour` has been renamed to `linebreak_behavior`. - Event `FileDragAndDrop::HoveredFileCancelled` has been renamed to `HoveredFileCanceled` - Function `Touches.just_cancelled` has been renamed to `Touches.just_canceled` - Event `TouchPhase::Cancelled` has been renamed to `TouchPhase::Canceled` ## Migration Guide Update where `linebreak_behaviour` is used to `linebreak_behavior` Updated the event `FileDragAndDrop::HoveredFileCancelled` where used to `HoveredFileCanceled` Update `Touches.just_cancelled` where used as `Touches.just_canceled` The event `TouchPhase::Cancelled` is now called `TouchPhase::Canceled`

bevy_reflect: `FromReflect` Ergonomics Implementation (#6056) # Objective **This implementation is based on https://github.com/bevyengine/rfcs/pull/59.** --- Resolves #4597 Full details and motivation can be found in the RFC, but here's a brief summary. `FromReflect` is a very powerful and important trait within the reflection API. It allows Dynamic types (e.g., `DynamicList`, etc.) to be formed into Real ones (e.g., `Vec<i32>`, etc.). This mainly comes into play concerning deserialization, where the reflection deserializers both return a `Box<dyn Reflect>` that almost always contain one of these Dynamic representations of a Real type. To convert this to our Real type, we need to use `FromReflect`. It also sneaks up in other ways. For example, it's a required bound for `T` in `Vec<T>` so that `Vec<T>` as a whole can be made `FromReflect`. It's also required by all fields of an enum as it's used as part of the `Reflect::apply` implementation. So in other words, much like `GetTypeRegistration` and `Typed`, it is very much a core reflection trait. The problem is that it is not currently treated like a core trait and is not automatically derived alongside `Reflect`. This makes using it a bit cumbersome and easy to forget. ## Solution Automatically derive `FromReflect` when deriving `Reflect`. Users can then choose to opt-out if needed using the `#[reflect(from_reflect = false)]` attribute. ```rust #[derive(Reflect)] struct Foo; #[derive(Reflect)] #[reflect(from_reflect = false)] struct Bar; fn test<T: FromReflect>(value: T) {} test(Foo); // <-- OK test(Bar); // <-- Panic! Bar does not implement trait `FromReflect` ``` #### `ReflectFromReflect` This PR also automatically adds the `ReflectFromReflect` (introduced in #6245) registration to the derived `GetTypeRegistration` impl— if the type hasn't opted out of `FromReflect` of course. <details> <summary><h4>Improved Deserialization</h4></summary> > **Warning** > This section includes changes that have since been descoped from this PR.

fix: upgrade to winit v0.30 (#13366) # Objective - Upgrade winit to v0.30 - Fixes https://github.com/bevyengine/bevy/issues/13331 ## Solution This is a rewrite/adaptation of the new trait system described and implemented in `winit` v0.30. ## Migration Guide The custom UserEvent is now renamed as WakeUp, used to wake up the loop if anything happens outside the app (a new [custom_user_event](https://github.com/bevyengine/bevy/pull/13366/files#diff-2de8c0a8d3028d0059a3d80ae31b2bbc1cde2595ce2d317ea378fe3e0cf6ef2d) shows this behavior. The internal `UpdateState` has been removed and replaced internally by the AppLifecycle. When changed, the AppLifecycle is sent as an event. The `UpdateMode` now accepts only two values: `Continuous` and `Reactive`, but the latter exposes 3 new properties to enable reactive to device, user or window events. The previous `UpdateMode::Reactive` is now equivalent to `UpdateMode::reactive()`, while `UpdateMode::ReactiveLowPower` to `UpdateMode::reactive_low_power()`. The `ApplicationLifecycle` has been renamed as `AppLifecycle`, and now contains the possible values of the application state inside the event loop: * `Idle`: the loop has not started yet * `Running` (previously called `Started`): the loop is running * `WillSuspend`: the loop is going to be suspended * `Suspended`: the loop is suspended * `WillResume`: the loop is going to be resumed Note: the `Resumed` state has been removed since the resumed app is just running. Finally, now that `winit` enables this, it extends the `WinitPlugin` to support custom events. ## Test platforms - [x] Windows - [x] MacOs - [x] Linux (x11) - [x] Linux (Wayland) - [x] Android - [x] iOS - [x] WASM/WebGPU - [x] WASM/WebGL2 ## Outstanding issues / regressions - [ ] iOS: build failed in CI - blocking, but may just be flakiness - [x] Cross-platform: when the window is maximised, changes in the scale factor don't apply, to make them apply one has to make the window smaller again. (Re-maximising keeps the updated scale factor) - non-blocking, but good to fix - [ ] Android: it's pretty easy to quickly open and close the app and then the music keeps playing when suspended. - non-blocking but worrying - [ ] Web: the application will hang when switching tabs - Not new, duplicate of https://github.com/bevyengine/bevy/issues/13486 - [ ] Cross-platform?: Screenshot failure, `ERROR present_frames: wgpu_core::present: No work has been submitted for this frame before` taking the first screenshot, but after pressing space - non-blocking, but good to fix --------- Co-authored-by: François <francois.mockers@vleue.com>

The internal `UpdateState` has been removed and replaced internally by the AppLifecycle. When changed, the AppLifecycle is sent as an event. The `UpdateMode` now accepts only two values: `Continuous` and `Reactive`, but the latter exposes 3 new properties to enable reactive to device, user or window events. The previous `UpdateMode::Reactive` is now equivalent to `UpdateMode::reactive()`, while `UpdateMode::ReactiveLowPower` to `UpdateMode::reactive_low_power()`. The `ApplicationLifecycle` has been renamed as `AppLifecycle`, and now contains the possible values of the application state inside the event loop: * `Idle`: the loop has not started yet * `Running` (previously called `Started`): the loop is running * `WillSuspend`: the loop is going to be suspended * `Suspended`: the loop is suspended * `WillResume`: the loop is going to be resumed Note: the `Resumed` state has been removed since the resumed app is just running. Finally, now that `winit` enables this, it extends the `WinitPlugin` to support custom events. ## Test platforms - [x] Windows - [x] MacOs - [x] Linux (x11) - [x] Linux (Wayland) - [x] Android - [x] iOS - [x] WASM/WebGPU - [x] WASM/WebGL2 ## Outstanding issues / regressions - [ ] iOS: build failed in CI - blocking, but may just be flakiness - [x] Cross-platform: when the window is maximised, changes in the scale factor don't apply, to make them apply one has to make the window smaller again. (Re-maximising keeps the updated scale factor) - non-blocking, but good to fix - [ ] Android: it's pretty easy to quickly open and close the app and then the music keeps playing when suspended. - non-blocking but worrying - [ ] Web: the application will hang when switching tabs - Not new, duplicate of https://github.com/bevyengine/bevy/issues/13486 - [ ] Cross-platform?: Screenshot failure, `ERROR present_frames: wgpu_core::present: No work has been submitted for this frame before` taking the first screenshot, but after pressing space - non-blocking, but good to fix --------- Co-authored-by: François <francois.mockers@vleue.com>

Picking event ordering (#14862) # Objective Correctly order picking events. Resolves https://github.com/bevyengine/bevy/issues/5984. ## Solution Event ordering [very long standing problem](https://github.com/aevyrie/bevy_mod_picking/issues/294) with mod picking, stemming from two related issues. The first problem was that `Pointer<T>` events of different types couldn't be ordered, but we have already gotten around that in the upstream by switching to observers. Since observers run in the order they are triggered, this isn't an issue. The second problem was that the underlying event streams that picking uses to create it's pointer interaction events *also* lacked ordering, and the systems that generated the points couldn't interleave events. This PR fixes that by unifying the event streams and integrating the various interaction systems. The concrete changes are as follows: + `bevy_winit::WinitEvent` has been moved to `bevy_window::WindowEvent`. This provides a unified (and more importantly, *ordered*) input stream for both `bevy_window` and `bevy_input` events. + Replaces `InputMove` and `InputPress` with `PointerInput`, a new unified input event which drives picking and interaction. This event is built to have drop-in forward compatibility with [winit's upcoming pointer abstraction](https://github.com/rust-windowing/winit/pull/3876). I have added code to emulate it using the current winit input abstractions, but this entire thing will be much more robust when it lands. + Rolls `pointer_events` `send_click_and_drag_events` and `send_drag_over_events` into a single system, which operates directly on `PointerEvent` and triggers observers as output. The PR also improves docs and takes the opportunity to refactor/streamline the pointer event dispatch logic. ## Status & Testing This PR is now feature complete and documented. While it is theoretically possible to add unit tests for the ordering, building the picking mocking for that will take a little while. Feedback on the chosen ordering of events is within-scope. ## Migration Guide For users switching from `bevy_mod_picking` to `bevy_picking`: + Instead of adding an `On<T>` component, use `.observe(|trigger: Trigger<T>|)`. You may now apply multiple handlers to the same entity using this command. + Pointer interaction events now have semi-deterministic ordering which (more or less) aligns with the order of the raw input stream. Consult the docs on `bevy_picking::event::pointer_events` for current information. You may need to adjust your event handling logic accordingly. + `PointerCancel` has been replaced with `Pointer<Cancled>`, which now has the semantics of an OS touch pointer cancel event. + `InputMove` and `InputPress` have been merged into `PointerInput`. The use remains exactly the same. + Picking interaction events are now only accessible through observers, and no `EventReader`. This functionality may be re-implemented later. For users of `bevy_winit`: + The event `bevy_winit::WinitEvent` has moved to `bevy_window::WindowEvent`. If this was the only thing you depended on `bevy_winit` for, you should switch your dependency to `bevy_window`. + `bevy_window` now depends on `bevy_input`. The dependencies of `bevy_input` are a subset of the existing dependencies for `bevy_window` so this should be non-breaking.
