Gamepad improvements (#16222)
# Objective

Closes #16221.

## Solution

- Make `Gamepad` fields public and remove delegates / getters.
- Move `impl Into` to `Axis` methods (delegates for `Axis` used `impl
Into` to allow passing both `GamepadAxis` and `GamepadButton`).
- Improve docs.

## Testing

- I run tests.

Not sure if the migration guide is needed, since it's a feature from RC,
but I wrote it just in case.

---

## Migration Guide

- `Gamepad` fields are now public.
- Instead of using `Gamepad` delegates like `Gamepad::just_pressed`,
call these methods directly on the fields.

fix: add reflect to SceneInstanceReady and other observers/events (#16018)
# Objective

Built-in observers & events should be `Reflect` so that components that
interact with them can be serialized in scenes. This is a similar pr to
#14259.

Add some missing features from the gamepads-as-entities change that were needed to update leafwing-input-manager. (#15685)
The gamepads-as-entities change caused several regressions. This patch
fixes each of them:

1. This PR introduces two new fields on `GamepadInfo`: `vendor_id`, and
`product_id`, as well as associated methods. These fields are simply
mirrored from the `gilrs` library.

2. That PR removed the methods that allowed iterating over all pressed
and released buttons, as well as the method that allowed iterating over
the axis values. (It was still technically possible to do so by using
reflection to access the private fields of `Gamepad`.)

3. The `Gamepad` component wasn't marked reflectable. This PR fixes that
problem.

These changes allowed me to forward port `leafwing-input-manager`.

Implement gamepads as entities (#12770)
# Objective

- Significantly improve the ergonomics of gamepads and allow new
features

Gamepads are a bit unergonomic to work with, they use resources but
unlike other inputs, they are not limited to a single gamepad, to get
around this it uses an identifier (Gamepad) to interact with anything
causing all sorts of issues.

1. There are too many: Gamepads, GamepadSettings, GamepadInfo,
ButtonInput<T>, 2 Axis<T>.
2. ButtonInput/Axis generic methods become really inconvenient to use
e.g. any_pressed()
3. GamepadButton/Axis structs are unnecessary boilerplate:

```rust
for gamepad in gamepads.iter() {
        if button_inputs.just_pressed(GamepadButton::new(gamepad, GamepadButtonType::South)) {
            info!("{:?} just pressed South", gamepad);
        } else if button_inputs.just_released(GamepadButton::new(gamepad, GamepadButtonType::South))
        {
            info!("{:?} just released South", gamepad);
        }
}
```
4. Projects often need to create resources to store the selected gamepad
and have to manually check if their gamepad is still valid anyways.

- Previously attempted by #3419 and #12674


## Solution

- Implement gamepads as entities.

Using entities solves all the problems above and opens new
possibilities.

1. Reduce boilerplate and allows iteration

```rust
let is_pressed = gamepads_buttons.iter().any(|buttons| buttons.pressed(GamepadButtonType::South))
```
2. ButtonInput/Axis generic methods become ergonomic again 
```rust
gamepad_buttons.any_just_pressed([GamepadButtonType::Start, GamepadButtonType::Select])
```
3. Reduces the number of public components significantly (Gamepad,
GamepadSettings, GamepadButtons, GamepadAxes)
4. Components are highly convenient. Gamepad optional features could now
be expressed naturally (`Option<Rumble> or Option<Gyro>`), allows devs
to attach their own components and filter them, so code like this
becomes possible:
```rust
fn move_player<const T: usize>(
    player: Query<&Transform, With<Player<T>>>,
    gamepads_buttons: Query<&GamepadButtons, With<Player<T>>>,
) {
    if let Ok(gamepad_buttons) = gamepads_buttons.get_single() {
        if gamepad_buttons.pressed(GamepadButtonType::South) {
            // move player
        }
    }
}
```

Add core and alloc over std Lints (#15281)
# Objective

- Fixes #6370
- Closes #6581

## Solution

- Added the following lints to the workspace:
  - `std_instead_of_core`
  - `std_instead_of_alloc`
  - `alloc_instead_of_core`
- Used `cargo +nightly fmt` with [item level use
formatting](https://rust-lang.github.io/rustfmt/?version=v1.6.0&search=#Item%5C%3A)
to split all `use` statements into single items.
- Used `cargo clippy --workspace --all-targets --all-features --fix
--allow-dirty` to _attempt_ to resolve the new linting issues, and
intervened where the lint was unable to resolve the issue automatically
(usually due to needing an `extern crate alloc;` statement in a crate
root).
- Manually removed certain uses of `std` where negative feature gating
prevented `--all-features` from finding the offending uses.
- Used `cargo +nightly fmt` with [crate level use
formatting](https://rust-lang.github.io/rustfmt/?version=v1.6.0&search=#Crate%5C%3A)
to re-merge all `use` statements matching Bevy's previous styling.
- Manually fixed cases where the `fmt` tool could not re-merge `use`
statements due to conditional compilation attributes.

## Testing

- Ran CI locally

## Migration Guide

The MSRV is now 1.81. Please update to this version or higher.

## Notes

- This is a _massive_ change to try and push through, which is why I've
outlined the semi-automatic steps I used to create this PR, in case this
fails and someone else tries again in the future.
- Making this change has no impact on user code, but does mean Bevy
contributors will be warned to use `core` and `alloc` instead of `std`
where possible.
- This lint is a critical first step towards investigating `no_std`
options for Bevy.

bevy_input: allow use without bevy_reflect (#14167)
# Objective

Allow use of `bevy_input` types without needing `bevy_reflect`.

## Solution

Make `bevy_reflect` within `bevy_input` optional. It's compiled in by
default.
Turn on reflect in dependencies as well when this feature is on.

## Testing

- Did you test these changes? If so, how?

I did a `cargo hack -p bevy_input --each-feature build`.

Derive Ord for GamepadButtonType. (#11791)
# Objective

Use `GamepadButtonType` with library that requires `Ord`.

## Motivation

`KeyCode` derives `Ord` that I'm using with a trie for recognizing
[input
sequences](https://github.com/shanecelis/bevy-input-sequence/tree/trie).
I would like to do the same for `GamepadButtonType` but am stymied by it
not deriving `Ord`.

## Solution

This PR add derivations PartialOrd and Ord for `GamepadButtonType`.

## Workaround

If deriving `Ord` is not possible, I'd be happy to know how I might
coerce `GamepadButtonType` into a `u32` or something else that is `Ord`,
so I can wrap `GamepadButtonType` in a newtype. I suppose serializing
with serde may work or reflect?

Update Event send methods to return EventId (#10551)
# Objective

- Fixes #10532

## Solution

I've updated the various `Event` send methods to return the sent
`EventId`(s). Since these methods previously returned nothing, and this
information is cheap to copy, there should be minimal negative
consequences to providing this additional information. In the case of
`send_batch`, an iterator is returned built from `Range` and `Map`,
which only consumes 16 bytes on the stack with no heap allocations for
all batch sizes. As such, the cost of this information is negligible.

These changes are reflected for `EventWriter` and `World`. For `World`,
the return types are optional to account for the possible lack of an
`Events` resource. Again, these methods previously returned no
information, so its inclusion should only be a benefit.

## Usage

Now when sending events, the IDs of those events is available for
immediate use:

```rust
// Example of a request-response system where the requester can track handled requests.

/// A system which can make and track requests
fn requester(
    mut requests: EventWriter<Request>,
    mut handled: EventReader<Handled>,
    mut pending: Local<HashSet<EventId<Request>>>,
) {
    // Check status of previous requests
    for Handled(id) in handled.read() {
        pending.remove(&id);
    }

    if !pending.is_empty() {
        error!("Not all my requests were handled on the previous frame!");
        pending.clear();
    }

    // Send a new request and remember its ID for later
    let request_id = requests.send(Request::MyRequest { /* ... */ });

    pending.insert(request_id);
}

/// A system which handles requests
fn responder(
    mut requests: EventReader<Request>,
    mut handled: EventWriter<Handled>,
) {
    for (request, id) in requests.read_with_id() {
        if handle(request).is_ok() {
            handled.send(Handled(id));
        }
    }
}
```

In the above example, a `requester` system can send request events, and
keep track of which ones are currently pending by `EventId`. Then, a
`responder` system can act on that event, providing the ID as a
reference that the `requester` can use. Before this PR, it was not
trivial for a system sending events to keep track of events by ID. This
is unfortunate, since for a system reading events, it is trivial to
access the ID of a event.

---

## Changelog

- Updated `Events`:
  - Added `send_batch`
  - Modified `send` to return the sent `EventId`
  - Modified `send_default` to return the sent `EventId`
- Updated `EventWriter`
  - Modified `send_batch` to return all sent `EventId`s
  - Modified `send` to return the sent `EventId`
  - Modified `send_default` to return the sent `EventId`
- Updated `World`
- Modified `send_event` to return the sent `EventId` if sent, otherwise
`None`.
- Modified `send_event_default` to return the sent `EventId` if sent,
otherwise `None`.
- Modified `send_event_batch` to return all sent `EventId`s if sent,
otherwise `None`.
- Added unit test `test_send_events_ids` to ensure returned `EventId`s
match the sent `Event`s
- Updated uses of modified methods.

## Migration Guide

### `send` / `send_default` / `send_batch`

For the following methods:

- `Events::send`
- `Events::send_default`
- `Events::send_batch`
- `EventWriter::send`
- `EventWriter::send_default`
- `EventWriter::send_batch`
- `World::send_event`
- `World::send_event_default`
- `World::send_event_batch`

Ensure calls to these methods either handle the returned value, or
suppress the result with `;`.

```rust
// Now fails to compile due to mismatched return type
fn send_my_event(mut events: EventWriter<MyEvent>) {
    events.send_default()
}

// Fix
fn send_my_event(mut events: EventWriter<MyEvent>) {
    events.send_default();
}
```

This will most likely be noticed within `match` statements:

```rust
// Before
match is_pressed {
    true => events.send(PlayerAction::Fire),
//                 ^--^ No longer returns ()
    false => {}
}

// After
match is_pressed {
    true => {
        events.send(PlayerAction::Fire);
    },
    false => {}
}
```

Make ButtonSettings.is_pressed/released public (#10534)
In gamepad.rs, `ButtonSettings` `is_pressed` and `is_released` are both
private, but their implementations use publicly available values.
Keeping them private forces consumers to unnecessarily re-implement this
logic, so just make them public.

Change AxisSettings livezone default (#10090)
# Objective

While using joysticks for player aiming, I noticed that there was as
`0.05` value snap on the axis. After searching through Bevy's code, I
saw it was the default livezone being at `0.95`. This causes any value
higher to snap to `1.0`. I think `1.0` and `-1.0` would be a better
default, as it gives all values to the joystick arc.
 
This default livezone stumped me for a bit as I thought either something
was broken or I was doing something wrong.

## Solution

Change the livezone defaults to ` livezone_upperbound: 1.0` and
`livezone_lowerbound: -1.0`.

---

## Migration Guide

If the default 0.05 was relied on, the default or gamepad `AxisSettings`
on the resource `GamepadSettings` will have to be changed.

input: allow multiple gamepad inputs to be registered for one button in one frame (#9446)
# Objective

- Currently, (AFAIC, accidentally) after registering an event for a
Gilrs button event, we ignore all subsequent events for the same button
in the same frame, because we don't update our filter. This is rare, but
I noticed it while adding gamepad support to a terminal app rendering at
15fps.
- Related to #4664, but does not quite fix it.

## Solution

- Move the edit to the `Axis<GamepadButton>` resource to when we read
the events from Gilrs.

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:🇩🇪: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:🇩🇪: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. 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.

* The reflect deserializers now perform a `FromReflect` conversion
internally. The expected output of `TypedReflectDeserializer::new` and
`UntypedReflectDeserializer::new` is no longer a Dynamic (e.g.,
`DynamicList`), but its Real counterpart (e.g., `Vec<i32>`).

  ```rust
let reflect_deserializer =
UntypedReflectDeserializer::new_dynamic(&registry);
  let mut deserializer = ron:🇩🇪:Deserializer::from_str(input)?;
  
  // OLD
let output: DynamicStruct = reflect_deserializer.deserialize(&mut
deserializer)?.take()?;
  
  // NEW
let output: SomeStruct = reflect_deserializer.deserialize(&mut
deserializer)?.take()?;
  ```

Alternatively, if this behavior isn't desired, use the
`TypedReflectDeserializer::new_dynamic` and
`UntypedReflectDeserializer::new_dynamic` methods instead:

  ```rust
  // OLD
  let reflect_deserializer = UntypedReflectDeserializer::new(&registry);
  
  // NEW
let reflect_deserializer =
UntypedReflectDeserializer::new_dynamic(&registry);
  ```

Add FromReflect where Reflect is used (#8776)
# Objective

Discovered that PointLight did not implement FromReflect. Adding
FromReflect where Reflect is used. I overreached and applied this rule
everywhere there was a Reflect without a FromReflect, except from where
the compiler wouldn't allow me.

Based from question: https://github.com/bevyengine/bevy/discussions/8774

## Solution

- Adding FromReflect where Reflect was already derived

## Notes

First PR I do in this ecosystem, so not sure if this is the usual
approach, that is, to touch many files at once.

Require #[derive(Event)] on all Events (#7086)
# Objective

Be consistent with `Resource`s and `Components` and have `Event` types
be more self-documenting.
Although not susceptible to accidentally using a function instead of a
value due to `Event`s only being initialized by their type, much of the
same reasoning for removing the blanket impl on `Resource` also applies
here.

* Not immediately obvious if a type is intended to be an event
* Prevent invisible conflicts if the same third-party or primitive types
are used as events
* Allows for further extensions (e.g. opt-in warning for missed events)

## Solution

Remove the blanket impl for the `Event` trait. Add a derive macro for
it.

---

## Changelog

- `Event` is no longer implemented for all applicable types. Add the
`#[derive(Event)]` macro for events.

## Migration Guide

* Add the `#[derive(Event)]` macro for events. Third-party types used as
events should be wrapped in a newtype.

Add gamepad rumble support to bevy_input (#8398)
# Objective

Provide the ability to trigger controller rumbling (force-feedback) with
a cross-platform API.

## Solution

This adds the `GamepadRumbleRequest` event to `bevy_input` and adds a
system in `bevy_gilrs` to read them and rumble controllers accordingly.

It's a relatively primitive API with a `duration` in seconds and
`GamepadRumbleIntensity` with values for the weak and strong gamepad
motors. It's is an almost 1-to-1 mapping to platform APIs. Some
platforms refer to these motors as left and right, and low frequency and
high frequency, but by convention, they're usually the same.

I used #3868 as a starting point, updated to main, removed the low-level
gilrs effect API, and moved the requests to `bevy_input` and exposed the
strong and weak intensities.

I intend this to hopefully be a non-controversial cross-platform
starting point we can build upon to eventually support more fine-grained
control (closer to the gilrs effect API)

---

## Changelog

### Added

- Gamepads can now be rumbled by sending the `GamepadRumbleRequest`
event.

d4e3fcdfbf Fix incorrect behavior of just_pressed and just_released in Input<GamepadButton> (#7238)
# 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

2f4cf76866 Fix axis settings constructor (#7233)
# 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.

9dd8fbc570 Added Ref to allow immutable access with change detection (#7097)
# 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.

e94215c4c6 Gamepad events refactor (#6965)
# 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.

f7c8eb7d86 Correct docs for ButtonSettingsError to read 0.0..=1.0 (#6570)
# 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.

2023ce63c7 Derive Reflect + FromReflect for input types (#6232)
# 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`.

bcc33f6757 feat: add GamepadInfo, expose gamepad names (#6342)
# 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.

---

## 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.

c11fbfb3e1 Add getters and setters for InputAxis and ButtonSettings (#6088)
# 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`.

bc863cec4d Derived Copy trait for bevy_input events, Serialize/Deserialize for events in bevy_input and bevy_windows, PartialEq for events in both, and Eq where possible in both. (#6023)
# 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.

7a29c707bf Gamepad type is Copy; do not require / return references to it in Gamepads API (#5296)
# 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`.

79e7c93060 Support for additional gamepad buttons and axis (#5853)
# 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.

992681b59b Make Resource trait opt-in, requiring #[derive(Resource)] V2 (#5577)
*This PR description is an edited copy of #5007, written by @alice-i-cecile.*
# Objective
Follow-up to https://github.com/bevyengine/bevy/pull/2254. The `Resource` trait currently has a blanket implementation for all types that meet its bounds.

While ergonomic, this results in several drawbacks:

* it is possible to make confusing, silent mistakes such as inserting a function pointer (Foo) rather than a value (Foo::Bar) as a resource
* it is challenging to discover if a type is intended to be used as a resource
* we cannot later add customization options (see the [RFC](https://github.com/bevyengine/rfcs/blob/main/rfcs/27-derive-component.md) for the equivalent choice for Component).
* dependencies can use the same Rust type as a resource in invisibly conflicting ways
* raw Rust types used as resources cannot preserve privacy appropriately, as anyone able to access that type can read and write to internal values
* we cannot capture a definitive list of possible resources to display to users in an editor
## Notes to reviewers
 * Review this commit-by-commit; there's effectively no back-tracking and there's a lot of churn in some of these commits.
   *ira: My commits are not as well organized :')*
 * I've relaxed the bound on Local to Send + Sync + 'static: I don't think these concerns apply there, so this can keep things simple. Storing e.g. a u32 in a Local is fine, because there's a variable name attached explaining what it does.
 * I think this is a bad place for the Resource trait to live, but I've left it in place to make reviewing easier. IMO that's best tackled with https://github.com/bevyengine/bevy/issues/4981.

## Changelog
`Resource` is no longer automatically implemented for all matching types. Instead, use the new `#[derive(Resource)]` macro.

## Migration Guide
Add `#[derive(Resource)]` to all types you are using as a resource.

If you are using a third party type as a resource, wrap it in a tuple struct to bypass orphan rules. Consider deriving `Deref` and `DerefMut` to improve ergonomics.

`ClearColor` no longer implements `Component`. Using `ClearColor` as a component in 0.8 did nothing.
Use the `ClearColorConfig` in the `Camera3d` and `Camera2d` components instead.

1fccb99d3a Improve Gamepad DPad Button Detection (#5220)
# 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.

51509a9a3e Change gamepad.rs tuples to normal structs (#4519)
# 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`.
