# Objective
I found several words in code and docs are incorrect. This should be fixed.
## Solution
- Fix several minor typos
Co-authored-by: Chris Ohk <utilforever@gmail.com>
# Objective
- Fixes a bug where `just_pressed` and `just_released` in `Input<GamepadButton>` might behave incorrectly due calling `clear` 3 times in a single frame through these three different systems: `gamepad_button_event_system`, `gamepad_axis_event_system` and `gamepad_connection_system` in any order
## Solution
- Call `clear` only once and before all the above three systems, i.e. in `gamepad_event_system`
## Additional Info
- Discussion in Discord: https://discord.com/channels/691052431525675048/768253008416342076/1064621963693273279
# Objective
Currently, the `AxisSettings::new` function is unusable due to
an implementation quirk. It only allows `AxisSettings` where
the bounds that are supposed to be positive are negative!
## Solution
- We fix the bound check
- We add a test to make sure the method is usable
Seems like the error slipped through because of the relatively
verbose code style. With all those `if/else`, very long names,
range syntax, the bound check is actually hard to spot. I first
refactored a lot of code, but I left out the refactor because the
fix should be integrated independently.
---
## Changelog
- Fix `AxisSettings::new` only accepting invalid bounds
# Objective
- Fixes#7066
## Solution
- Split the ChangeDetection trait into ChangeDetection and ChangeDetectionMut
- Added Ref as equivalent to &T with change detection
---
## Changelog
- Support for Ref which allow inspecting change detection flags in an immutable way
## Migration Guide
- While bevy prelude includes both ChangeDetection and ChangeDetectionMut any code explicitly referencing ChangeDetection might need to be updated to ChangeDetectionMut or both. Specifically any reading logic requires ChangeDetection while writes requires ChangeDetectionMut.
use bevy_ecs::change_detection::DetectChanges -> use bevy_ecs::change_detection::{DetectChanges, DetectChangesMut}
- Previously Res had methods to access change detection `is_changed` and `is_added` those methods have been moved to the `DetectChanges` trait. If you are including bevy prelude you will have access to these types otherwise you will need to `use bevy_ecs::change_detection::DetectChanges` to continue using them.
# Objective
- Remove redundant gamepad events
- Simplify consuming gamepad events.
- Refactor: Separate handling of gamepad events into multiple systems.
## Solution
- Removed `GamepadEventRaw`, and `GamepadEventType`.
- Added bespoke `GamepadConnectionEvent`, `GamepadAxisChangedEvent`, and `GamepadButtonChangedEvent`.
- Refactored `gamepad_event_system`.
- Added `gamepad_button_event_system`, `gamepad_axis_event_system`, and `gamepad_connection_system`, which update the `Input` and `Axis` resources using their corresponding event type.
Gamepad events are now handled in their own systems and have their own types.
This allows for querying for gamepad events without having to match on `GamepadEventType` and makes creating handlers for specific gamepad event types, like a `GamepadConnectionEvent` or `GamepadButtonChangedEvent` possible.
We remove `GamepadEventRaw` by filtering the gamepad events, using `GamepadSettings`, _at the source_, in `bevy_gilrs`. This way we can create `GamepadEvent`s directly and avoid creating `GamepadEventRaw` which do not pass the user defined filters.
We expose ordered `GamepadEvent`s and we can respond to individual gamepad event types.
## Migration Guide
- Replace `GamepadEvent` and `GamepadEventRaw` types with their specific gamepad event type.
(github made me type out a message for the commit which looked like it was for the pr, sorry)
# Objective
- Add a way to get all of the input devices of an `Axis`, primarily useful for looping through them
## Solution
- Adds `Axis<T>::devices()` which returns a `FixedSizeIterator<Item = &T>`
- Adds a (probably unneeded) `test_axis_devices` test because tests are cool.
---
## Changelog
- Added `Axis<T>::devices()` method
## Migration Guide
Not a breaking change.
# Objective
The [documentation for `ButtonSettingsError`](https://docs.rs/bevy/0.9.0/bevy/input/gamepad/enum.ButtonSettingsError.html) incorrectly describes the valid range of values as `0.0..=2.0`, probably because it was copied from `AxisSettingsError`. The actual range, as seen in the functions that return it and in its own `thiserror` description, is `0.0..=1.0`.
## Solution
Update the doc comments to reflect the correct range.

This reverts commit 53d387f340.
# Objective
Reverts #6448. This didn't have the intended effect: we're now getting bevy::prelude shown in the docs again.
Co-authored-by: Alejandro Pascual <alejandro.pascual.pozo@gmail.com>
# Objective
- Right now re-exports are completely hidden in prelude docs.
- Fixes#6433
## Solution
- We could show the re-exports without inlining their documentation.
# Objective
Adds support for reflecting many more of the input types. This allows those types to be used via scripting, `bevy-inspector-egui`, etc. These types are registered by the `InputPlugin` so that they're automatically available to anyone who wants to use them
Closes#6223
## Solution
Many types now have `#[derive(Reflect, FromReflect)]` added to them in `bevy_input`. Additionally, `#[reflect(traits...)]` has been added for applicable traits to the types.
This PR does not add reflection support for types which have private fields. Notably, `Touch` and `Touches` don't implement `Reflect`/`FromReflect`.
This adds the "glam" feature to the `bevy_reflect` dependency for package `bevy_input`. Since `bevy_input` transitively depends on `glam` already, all this brings in are the reflection `impl`s.
## Migration Guide
- `Input<T>` now implements `Reflect` via `#[reflect]` instead of `#[reflect_value]`. This means it now exposes its private fields via the `Reflect` trait rather than being treated as a value type. For code that relies on the `Input<T>` struct being treated as a value type by reflection, it is still possible to wrap the `Input<T>` type with a wrapper struct and apply `#[reflect_value]` to it.
- As a reminder, private fields exposed via reflection are not subject to any stability guarantees.
---
## Changelog
Added
- Implemented `Reflect` + `FromReflect` for many input-related types. These types are automatically registered when adding the `InputPlugin`.
# Objective
Fixes#6339.
## Solution
This PR adds a new type, `GamepadInfo`, which holds metadata associated with a particular `Gamepad`. The `Gamepads` resource now holds a `HashMap<Gamepad, GamepadInfo>`. The `GamepadInfo` is created when the gamepad backend (by default `bevy_gilrs`) emits a "gamepad connected" event.
The `gamepad_viewer` example has been updated to showcase the new functionality.
Before:
After:
---
## Changelog
### Added
- Added `GamepadInfo`.
- Added `Gamepads::name()`, which returns the name of the specified gamepad if it exists.
### Changed
- `GamepadEventType::Connected` is now a tuple variant with a single field of type `GamepadInfo`.
- Since `GamepadInfo` is not `Copy`, `GamepadEventType` is no longer `Copy`. The same is true of `GamepadEvent` and `GamepadEventRaw`.
## Migration Guide
- Pattern matches on `GamepadEventType::Connected` will need to be updated, as the form of the variant has changed.
- Code that requires `GamepadEvent`, `GamepadEventRaw` or `GamepadEventType` to be `Copy` will need to be updated.
# Objective
Fixes https://github.com/bevyengine/bevy/issues/3418
## Solution
Originally a rebase of https://github.com/bevyengine/bevy/pull/3446. Work was originally done by mfdorst, who should receive considerable credit. Then the error types were extensively reworked by targrub.
## Migration Guide
`AxisSettings` now has a `new()`, which may return an `AxisSettingsError`.
`AxisSettings` fields made private; now must be accessed through getters and setters. There's a dead zone, from `.deadzone_upperbound()` to `.deadzone_lowerbound()`, and a live zone, from `.deadzone_upperbound()` to `.livezone_upperbound()` and from `.deadzone_lowerbound()` to `.livezone_lowerbound()`.
`AxisSettings` setters no longer panic.
`ButtonSettings` fields made private; now must be accessed through getters and setters.
`ButtonSettings` now has a `new()`, which may return a `ButtonSettingsError`.

# Objective
- `process_touch_event` in `bevy_input` don't update position info. `TouchPhase::Ended` and `TouchPhase::Cancelled` should use the position info from `pressed`. Otherwise, it'll not update. The position info is updated from `TouchPhase::Moved`.
## Solution
- Use updated touch info.

> This section is optional. If this was a trivial fix, or has no externally-visible impact, feel free to skip this section.
- Fixed: bevy_input, fix process touch event, update touch info
# Objective
The [Stageless RFC](https://github.com/bevyengine/rfcs/pull/45) involves allowing exclusive systems to be referenced and ordered relative to parallel systems. We've agreed that unifying systems under `System` is the right move.
This is an alternative to #4166 (see rationale in the comments I left there). Note that this builds on the learnings established there (and borrows some patterns).
## Solution
This unifies parallel and exclusive systems under the shared `System` trait, removing the old `ExclusiveSystem` trait / impls. This is accomplished by adding a new `ExclusiveFunctionSystem` impl similar to `FunctionSystem`. It is backed by `ExclusiveSystemParam`, which is similar to `SystemParam`. There is a new flattened out SystemContainer api (which cuts out a lot of trait and type complexity).
This means you can remove all cases of `exclusive_system()`:
```rust
// before
commands.add_system(some_system.exclusive_system());
// after
commands.add_system(some_system);
```
I've also implemented `ExclusiveSystemParam` for `&mut QueryState` and `&mut SystemState`, which makes this possible in exclusive systems:
```rust
fn some_exclusive_system(
world: &mut World,
transforms: &mut QueryState<&Transform>,
state: &mut SystemState<(Res<Time>, Query<&Player>)>,
) {
for transform in transforms.iter(world) {
println!("{transform:?}");
}
let (time, players) = state.get(world);
for player in players.iter() {
println!("{player:?}");
}
}
```
Note that "exclusive function systems" assume `&mut World` is present (and the first param). I think this is a fair assumption, given that the presence of `&mut World` is what defines the need for an exclusive system.
I added some targeted SystemParam `static` constraints, which removed the need for this:
``` rust
fn some_exclusive_system(state: &mut SystemState<(Res<'static, Time>, Query<&'static Player>)>) {}
```
## Related
- #2923
- #3001
- #3946
## Changelog
- `ExclusiveSystem` trait (and implementations) has been removed in favor of sharing the `System` trait.
- `ExclusiveFunctionSystem` and `ExclusiveSystemParam` were added, enabling flexible exclusive function systems
- `&mut SystemState` and `&mut QueryState` now implement `ExclusiveSystemParam`
- Exclusive and parallel System configuration is now done via a unified `SystemDescriptor`, `IntoSystemDescriptor`, and `SystemContainer` api.
## Migration Guide
Calling `.exclusive_system()` is no longer required (or supported) for converting exclusive system functions to exclusive systems:
```rust
// Old (0.8)
app.add_system(some_exclusive_system.exclusive_system());
// New (0.9)
app.add_system(some_exclusive_system);
```
Converting "normal" parallel systems to exclusive systems is done by calling the exclusive ordering apis:
```rust
// Old (0.8)
app.add_system(some_system.exclusive_system().at_end());
// New (0.9)
app.add_system(some_system.at_end());
```
Query state in exclusive systems can now be cached via ExclusiveSystemParams, which should be preferred for clarity and performance reasons:
```rust
// Old (0.8)
fn some_system(world: &mut World) {
let mut transforms = world.query::<&Transform>();
for transform in transforms.iter(world) {
}
}
// New (0.9)
fn some_system(world: &mut World, transforms: &mut QueryState<&Transform>) {
for transform in transforms.iter(world) {
}
}
```
# Objective
Add traits to events in `bevy_input` and `bevy_windows`: `Copy`, `Serialize`/`Deserialize`, `PartialEq`, and `Eq`, as requested in https://github.com/bevyengine/bevy/issues/6022, https://github.com/bevyengine/bevy/issues/6023, https://github.com/bevyengine/bevy/issues/6024.
## Solution
Added the traits to events in `bevy_input` and `bevy_windows`. Added dependency of `serde` in `Cargo.toml` of `bevy_input`.
## Migration Guide
If one has been `.clone()`'ing `bevy_input` events, Clippy will now complain about that. Just remove `.clone()` to solve.
## Other Notes
Some events in `bevy_input` had `f32` fields, so `Eq` trait was not derived for them.
Some events in `bevy_windows` had `String` fields, so `Copy` trait was not derived for them.

# Objective
- I'm currently working on being able to call methods on reflect types (https://github.com/jakobhellermann/bevy_reflect_fns)
- for that, I'd like to add methods to the `Input<KeyCode>` resource (which I'm doing by registering type data)
- implementing `Reflect` is currently a requirement for having type data in the `TypeRegistry`
## Solution
- derive `Reflect` for `KeyCode` and `Input`
- uses `#[reflect_value]` for `Input`, since it's fields aren't supposed to be observable
- using reflect_value would need `Clone` bounds on `T`, but since all the methods (`.pressed` etc) already require `T: Copy`, I unified everything to requiring `Copy`
- add `Send + Sync + 'static` bounds, also required by reflect derive
## Unrelated improvements
I can extract into a separate PR if needed.
- the `Reflect` derive would previously ignore `#[reflect_value]` and only accept `#[reflect_value()]` which was a bit confusing
- the generated code used `val.clone()` on a reference, which is fine if `val` impls `Clone`, but otherwise also compiles with a worse error message. Change to `std::clone::Clone::clone(val)` instead which gives a neat `T does not implement Clone` error
# Objective
- The `Gamepad` type is a tiny value-containing type that implements `Copy`.
- By convention, references to `Copy` types should be avoided, as they can introduce overhead and muddle the semantics of what's going on.
- This allows us to reduce boilerplate reference manipulation and lifetimes in user facing code.
## Solution
- Make assorted methods on `Gamepads` take / return a raw `Gamepad`, rather than `&Gamepad`.
## Migration Guide
- `Gamepads::iter` now returns an iterator of `Gamepad`. rather than an iterator of `&Gamepad`.
- `Gamepads::contains` now accepts a `Gamepad`, rather than a `&Gamepad`.
# Objective
Extend the scope of Gamepad to accommodate devices that have more inputs than a typical controller.
## Solution
Add additional enum variants to both _GamepadButtonType_ and _GamepadAxisType_ that supports up to 255 more non-standard buttons/axis respectively.
## Personal motivation
I have been writing an alternative to the GILRS crate, and with this simple change to the source code, It will be a trivial thing to direct new devices through the bevy systems, even when they do not always behave exactly like your typical controller.
*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.

# Objective
- I wanted to have controls independent from keyboard layout and found that bevy doesn't have a proper implementation for that
## Solution
- I created a `ScanCode` enum with two hundreds scan codes and updated `keyboard_input_system` to include and update `ResMut<Input<ScanCode>>`
- closes both https://github.com/bevyengine/bevy/issues/2052 and https://github.com/bevyengine/bevy/issues/862

# Objective
- Fixes#5544
- Part of the splitting process of #3692.
## Solution
- Document everything in the `gamepad.rs` file.
- Add a doc example for mocking gamepad input.
---
## Changelog
- Added and updated the documentation inside of the `gamepad.rs` file.
Generally a good idea.
I ran into this because I wanted to store `Gamepads` in a wrapper struct in https://github.com/Leafwing-Studios/leafwing-input-manager/pull/168.
This PR allows the `Debug` derive used there to continue working. I could workaround this with a custom impl, but a PR upstream seemed like the right fix.
# Objective
- Enable the `axis_dpad_to_button` gilrs filter to map hats to dpad buttons on supported remotes.
- Fixes https://github.com/Leafwing-Studios/leafwing-input-manager/issues/149
- Might have fixed the confusion related to https://github.com/bevyengine/bevy/issues/3229
## Solution
- Enables the `axis_dpad_to_button` filter in `gilrs` which will use it's remote mapping information to see if there are hats mapped to dpads for that remote model. I don't really understand the logic it uses exactly, but it is usually enabled by default in gilrs and I believe it probably leads to more intuitive mapping compared to the current situation of dpad buttons being mapped to an axis.
- Removes the `GamepadAxisType::DPadX` and `GamepadAxisType::DPadY` enum variants to avoid user confusion. Those variants should never be emitted anyway, for all supported remotes.
---
## Changelog
### Changed
- Removed `GamepadAxisType::DPadX` and `GamepadAxisType::DPadY` in favor of using `GamepadButtonType::DPad[Up/Down/Left/Right]` instead.
## Migration Guide
If your game reads gamepad events or queries the axis state of `GamePadAxisType::DPadX` or `GamePadAxisType::DPadY`, then you must migrate your code to check whether or not the `GamepadButtonType::DPadUp`, `GamepadButtonType::DPadDown`, etc. buttons were pressed instead.
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.
# Objective
- Fixes#5083
## Solution
I looked at the implementation of those events. I noticed that they both are adaptations of `winit`'s `DeviceEvent`/`WindowEvent` enum variants. Therefore I based the description of the items on the documentation provided by the upstream crate. I also added a link to `CursorMoved`, just like `MouseMotion` already has.
## Observations
- Looking at the implementation of `MouseMotion`, I noticed the `DeviceId` field of the `winit` event is discarded by `bevy_input`. This means that in the case a machine has multiple pointing devices, it is impossible to distinguish to which one the event is referring to. **EDIT:** just tested, `MouseMotion` events are emitted for movement of both mice.
# Objective
`bevy_ui` doesn't support correctly touch inputs because of two problems in the focus system:
- It attempts to retrieve touch input with a specific `0` id
- It doesn't retrieve touch positions and bases its focus solely on mouse position, absent from mobile devices
## Solution
I added a few methods to the `Touches` resource, allowing to check if **any** touch input was pressed, released or cancelled and to retrieve the *position* of the first pressed touch input and adapted the focus system.
I added a test button to the *iOS* example and it works correclty on emulator. I did not test on a real touch device as:
- Android is not working (https://github.com/bevyengine/bevy/issues/3249)
- I don't have an iOS device
# Objective
- Part of the splitting process of #3692.
## Solution
- Document `keyboard.rs` inside of `bevy_input`.

# 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.
# Objective
- Part of the splitting process of #3692.
## Solution
- Remove / change the tuple structs inside of `gamepad.rs` of `bevy_input` to normal structs.
## Reasons
- It made the `gamepad_connection_system` cleaner.
- It made the `gamepad_input_events.rs` example cleaner (which is probably the most notable change for the user facing API).
- Tuple structs are not descriptive (`.0`, `.1`).
- Using tuple structs for more than 1 field is a bad idea (This means that the `Gamepad` type might be fine as a tuple struct, but I still prefer normal structs over tuple structs).
Feel free to discuss this change as this is more or less just a matter of taste.
## Changelog
### Changed
- The `Gamepad`, `GamepadButton`, `GamepadAxis`, `GamepadEvent` and `GamepadEventRaw` types are now normal structs instead of tuple structs and have a `new()` function.
## Migration Guide
- The `Gamepad`, `GamepadButton`, `GamepadAxis`, `GamepadEvent` and `GamepadEventRaw` types are now normal structs instead of tuple structs and have a `new()` function. To migrate change every instantiation to use the `new()` function instead and use the appropriate field names instead of `.0` and `.1`.
# Objective
- Part of the splitting process of #3692.
## Solution
- Document `mouse.rs` inside of `bevy_input`.
Co-authored-by: KDecay <KDecayMusic@protonmail.com>
# Objective
- Part of the splitting process of #3692.
## Solution
- Add more tests to `input.rs` inside of `bevy_input`.
## Note
- The tests would now catch a change like #4410 and fail accordingly.
# Objective
- Part of the splitting process of #3692.
## Solution
- Rename `ElementState` to `ButtonState`
## Reasons
- The old name was too generic.
- If something can be pressed it is automatically button-like (thanks to @alice-i-cecile for bringing it up in #3692).
- The reason it is called `ElementState` is because that's how `winit` calls it.
- It is used to define if a keyboard or mouse **button** is pressed or not.
- Discussion in #3692.
## Changelog
### Changed
- The `ElementState` type received a rename and is now called `ButtonState`.
## Migration Guide
- The `ElementState` type received a rename and is now called `ButtonState`. To migrate you just have to change every occurrence of `ElementState` to `ButtonState`.

# Objective
- Revert #4410
- `Input<T>.clear()` is the method call at the end of each frame for inputs. Clearing `pressed` in it mean that checking if a key is pressed will always return false
# Objective
- Part of the splitting process of #3692.
## Solution
- Change the `gamepad_connection_system` to run after the `InputSystem` label.
## Reasons
I changed the `gamepad_connection_system` to run after the `InputSystem` instead of in parallel, because this system checks the `GamepadEvent`s which get send inside of the `gamepad_event_system`. This means that the `gamepad_connection_system` could respond to the events one frame later, instead of instantly resulting in one frame lag.
Old possible case:
1. `gamepad_connection_system` (reacts to the `GamepadEvent`s too early)
2. `gamepad_event_system` (sends the `GamepadEvent`s)
New fixed ordering:
1. `gamepad_event_system` (sends the `GamepadEvent`s)
2. `gamepad_connection_system` (reacts to the `GamepadEvent`s)
# Objective
We are currently inserting an `input` into `pressed` even if it is already pressed. This also applies to releasing an input. This is not a big deal, but since we are already checking if the `input` is pressed or not we might as well remove the cost of the value update caused by the `pressed.insert` method.
Related to #4209
## Solution
Only insert or remove input if needed.
# Objective
- Fixes#4208
## Solution
- Adds a check before inserting into an `Input`'s `just_released` set, in the same way that one exists for adding into the `just_pressed` set.
