# Objective
I would like to know if an event was emitted because of "key repeats" or
not.
Winit already exposes this information, but it isn't sent along by Bevy,
which this PR intends to address.
## Solution
Expose
[`winit::event::KeyEvent::repeat`](https://docs.rs/winit/0.30.3/winit/event/struct.KeyEvent.html#structfield.repeat)
in
[`bevy::input:⌨️:KeyboardInput`](https://docs.rs/bevy/0.14.0/bevy/input/keyboard/struct.KeyboardInput.html).
## Testing
Just hold any regular key down and only the first event should have
`KeyboardInput::repeat` set to `false`. Most OSs have "key repeat"
enabled by default.
---
## Changelog
- Added `KeyboardInput::repeat` signifying if this event was sent in
response to a "key repeat" event or not.

# 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`.

# Objective
- Add the `AccumulatedMouseMotion` and `AccumulatedMouseScroll`
resources to make it simpler to track mouse motion/scroll changes
- Closes#13915
## Solution
- Created two resources, `AccumulatedMouseMotion` and
`AccumulatedMouseScroll`, and a method that tracks the `MouseMotion` and
`MouseWheel` events and accumulates their deltas every frame.
- Also modified the mouse input example to show how to use the
resources.
## Testing
- Tested the changes by modifying an existing example to use the newly
added resources, and moving/scrolling my trackpad around a ton.

This was adopted from #12878. I rebased the changes resolved the
following merge conflicts:
- moved over the changes originally done in bevy_winit/src/lib.rs's
`handle_winit_event` into bevy_winit/src/state.rs's `window_event`
function
- moved WinitEvent::KeyboardFocusLost event forwarding originally done
in bevy_winit/src/winit_event.rs to the equivalent in
bevy_winit/src/state.rs
Tested this by following the modified keyboard_input example from the
original PR.
First, I verified I could reproduce the issue without the changes. Then,
after applying the changes, I verified that when I Alt+Tabbed away from
the running example that the log showed I released Alt and when I tabbed
back it didn't behave like Alt was stuck.
The following is from the original pull request by @gavlig
# Objective
This helps avoiding stuck key presses after switching from and back to
Bevy window. Key press event gets stuck because window loses focus
before receiving a key release event thus we end up with false positive
in ButtonInput.
## Solution
I saw two ways to fix this:
1. add bevy_window as dependency and read WindowFocus events
2. add a KeyboardFocusLost event specifically for this.
I chose the latter because adding another dependency felt wrong, but if
that is more preferable changing this pr won't be a problem. Also if
someone sees another way please let me know.
To test the bug use this small modification over
examples/keyboard_input.rs: (it will work only if you have Alt-Tab
combination for switching between windows in your OS, otherwise change
AltLeft accordingly)
```
//! Demonstrates handling a key press/release.
use bevy::{prelude::*, input:⌨️:KeyboardInput};
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_systems(Update, keyboard_input_system)
.run();
}
/// This system prints 'Alt' key state
fn keyboard_input_system(keyboard_input: Res<ButtonInput<KeyCode>>, mut
keyboard_input_events: EventReader<KeyboardInput>) {
for event in keyboard_input_events.read() {
info!("{:?}", event);
}
if keyboard_input.pressed(KeyCode::AltLeft) {
info!("'Alt' currently pressed");
}
if keyboard_input.just_pressed(KeyCode::AltLeft) {
info!("'Alt' just pressed");
}
if keyboard_input.just_released(KeyCode::AltLeft) {
info!("'Alt' just released");
}
}
```
Here i made a quick video with demo of the fix:
https://youtu.be/qTvUCk4IHvo In first part i press Alt and Alt+Tab to
switch back and forth from example app, logs will indicate that too. In
second part I applied fix and you'll see that Alt will no longer be
pressed when window gets unfocused

# Objective
Extracts the state mechanisms into a new crate called "bevy_state".
This comes with a few goals:
- state wasn't really an inherent machinery of the ecs system, and so
keeping it within bevy_ecs felt forced
- by mixing it in with bevy_ecs, the maintainability of our more robust
state system was significantly compromised
moving state into a new crate makes it easier to encapsulate as it's own
feature, and easier to read and understand since it's no longer a
single, massive file.
## Solution
move the state-related elements from bevy_ecs to a new crate
## Testing
- Did you test these changes? If so, how? all the automated tests
migrated and passed, ran the pre-existing examples without changes to
validate.
---
## Migration Guide
Since bevy_state is now gated behind the `bevy_state` feature, projects
that use state but don't use the `default-features` will need to add
that feature flag.
Since it is no longer part of bevy_ecs, projects that use bevy_ecs
directly will need to manually pull in `bevy_state`, trigger the
StateTransition schedule, and handle any of the elements that bevy_app
currently sets up.

# Objective
- `README.md` is a common file that usually gives an overview of the
folder it is in.
- When on <https://crates.io>, `README.md` is rendered as the main
description.
- Many crates in this repository are lacking `README.md` files, which
makes it more difficult to understand their purpose.
<img width="1552" alt="image"
src="https://github.com/bevyengine/bevy/assets/59022059/78ebf91d-b0c4-4b18-9874-365d6310640f">
- There are also a few inconsistencies with `README.md` files that this
PR and its follow-ups intend to fix.
## Solution
- Create a `README.md` file for all crates that do not have one.
- This file only contains the title of the crate (underscores removed,
proper capitalization, acronyms expanded) and the <https://shields.io>
badges.
- Remove the `readme` field in `Cargo.toml` for `bevy` and
`bevy_reflect`.
- This field is redundant because [Cargo automatically detects
`README.md`
files](https://doc.rust-lang.org/cargo/reference/manifest.html#the-readme-field).
The field is only there if you name it something else, like `INFO.md`.
- Fix capitalization of `bevy_utils`'s `README.md`.
- It was originally `Readme.md`, which is inconsistent with the rest of
the project.
- I created two commits renaming it to `README.md`, because Git appears
to be case-insensitive.
- Expand acronyms in title of `bevy_ptr` and `bevy_utils`.
- In the commit where I created all the new `README.md` files, I
preferred using expanded acronyms in the titles. (E.g. "Bevy Developer
Tools" instead of "Bevy Dev Tools".)
- This commit changes the title of existing `README.md` files to follow
the same scheme.
- I do not feel strongly about this change, please comment if you
disagree and I can revert it.
- Add <https://shields.io> badges to `bevy_time` and `bevy_transform`,
which are the only crates currently lacking them.
---
## Changelog
- Added `README.md` files to all crates missing it.
# Objective
Fixes#12470
This adds a examples for `ButtonInput` with `KeyCode`, `MouseButton`,
and `GamepadButton`.
It also includes an example of checking a multi-key combination, and
checking multiple keys to mean roughly the same thing.
Adjusted the documentation to better describe the performance cost of
`ButtonInput::any_just_pressed|any_just_released|any_pressed`.
Each function iterates the full input, but each check is expected
constant cost. It was described previously as a full input check, and a
full internal list iteration, which I believe is incorrect.
# Objective
- Fixes#12976
## Solution
This one is a doozy.
- Run `cargo +beta clippy --workspace --all-targets --all-features` and
fix all issues
- This includes:
- Moving inner attributes to be outer attributes, when the item in
question has both inner and outer attributes
- Use `ptr::from_ref` in more scenarios
- Extend the valid idents list used by `clippy:doc_markdown` with more
names
- Use `Clone::clone_from` when possible
- Remove redundant `ron` import
- Add backticks to **so many** identifiers and items
- I'm sorry whoever has to review this
---
## Changelog
- Added links to more identifiers in documentation.
# Objective
Fixes#12442
## Solution
Change `process_touch_event` to not update previous_position /
previous_force, and change it once per frame in
`touch_screen_input_system`.
# Objective
Resolves#3824. `unsafe` code should be the exception, not the norm in
Rust. It's obviously needed for various use cases as it's interfacing
with platforms and essentially running the borrow checker at runtime in
the ECS, but the touted benefits of Bevy is that we are able to heavily
leverage Rust's safety, and we should be holding ourselves accountable
to that by minimizing our unsafe footprint.
## Solution
Deny `unsafe_code` workspace wide. Add explicit exceptions for the
following crates, and forbid it in almost all of the others.
* bevy_ecs - Obvious given how much unsafe is needed to achieve
performant results
* bevy_ptr - Works with raw pointers, even more low level than bevy_ecs.
* bevy_render - due to needing to integrate with wgpu
* bevy_window - due to needing to integrate with raw_window_handle
* bevy_utils - Several unsafe utilities used by bevy_ecs. Ideally moved
into bevy_ecs instead of made publicly usable.
* bevy_reflect - Required for the unsafe type casting it's doing.
* bevy_transform - for the parallel transform propagation
* bevy_gizmos - For the SystemParam impls it has.
* bevy_assets - To support reflection. Might not be required, not 100%
sure yet.
* bevy_mikktspace - due to being a conversion from a C library. Pending
safe rewrite.
* bevy_dynamic_plugin - Inherently unsafe due to the dynamic loading
nature.
Several uses of unsafe were rewritten, as they did not need to be using
them:
* bevy_text - a case of `Option::unchecked` could be rewritten as a
normal for loop and match instead of an iterator.
* bevy_color - the Pod/Zeroable implementations were replaceable with
bytemuck's derive macros.
# Objective
Currently the built docs only shows the logo and favicon for the top
level `bevy` crate. This makes views like
https://docs.rs/bevy_ecs/latest/bevy_ecs/ look potentially unrelated to
the project at first glance.
## Solution
Reproduce the docs attributes for every crate that Bevy publishes.
Ideally this would be done with some workspace level Cargo.toml control,
but AFAICT, such support does not exist.
# Objective
- Clarify that `ButtonInput::just_release` and
`ButtonInput::just_pressed` don't imply information about the state of
`ButtonInput::pressed` or their counterparts.
# Objective
Fixes#10106
Adds a table showing computational complexity, as seen for Query (and
similar to std::collections docs).
## Solution
Add the complexity table

# Objective
Fix missing `TextBundle` (and many others) which are present in the main
crate as default features but optional in the sub-crate. See:
- https://docs.rs/bevy/0.13.0/bevy/ui/node_bundles/index.html
- https://docs.rs/bevy_ui/0.13.0/bevy_ui/node_bundles/index.html
~~There are probably other instances in other crates that I could track
down, but maybe "all-features = true" should be used by default in all
sub-crates? Not sure.~~ (There were many.) I only noticed this because
rust-analyzer's "open docs" features takes me to the sub-crate, not the
main one.
## Solution
Add "all-features = true" to docs.rs metadata for crates that use
features.
## Changelog
### Changed
- Unified features documented on docs.rs between main crate and
sub-crates
# Objective
`ButtonInput<KeyCode>` documentation is currently incorrect/incomplete,
see #12273.
## Solution
Fix the documentation.
I think in the future we should also stop triggering
`just_pressed`/`just_released` when focus switches between two Bevy
windows, as those functions are independent of the window. It could also
make sense to add individual `ButtonInput<KeyCode>`s per window.

# Objective
Fix#12304. Remove unnecessary type registrations thanks to #4154.

Conservatively remove type registrations. Keeping the top level
components, resources, and events, but dropping everything else that is
a type of a member of those types.
# Objective
Correct references to `Input` into `ButtonInput` in the keyboard input
docs since it was renamed in 0.13.
## Solution
Change the type used in the keyboard input docs from `Input` to
`ButtonInput`.

# Objective
- The `touch_screen_input_system` system runs on every tick.
- It unconditionally calls `update(&mut self)`, on the `Touches`
resource.
- This blocks the usage of a `resource_changed::<Touches>` run
condition.
## Solution
- Remove `update(&mut self)` as it's only used in this one system, and
in-lining the method implementation removes an indirection to an
ambiguously named method.
- Add conditional checks around the calls to clearing the internal maps.

# 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?
# Objective
Currently the `missing_docs` lint is allowed-by-default and enabled at
crate level when their documentations is complete (see #3492).
This PR proposes to inverse this logic by making `missing_docs`
warn-by-default and mark crates with imcomplete docs allowed.
## Solution
Makes `missing_docs` warn at workspace level and allowed at crate level
when the docs is imcomplete.
# Objective
Rust analyzer kept complaining about a cyclic dependency due to
`bevy_input` having a dev-dependency on `bevy`.
`bevy_input` was also missing `bevy_reflect`'s "smol_str" feature which
it needs to compile on its own.
Fixes#10256
## Solution
Remove the dev-dependency on `bevy` from `bevy_input` since it was only
used to reduce imports for 1 test and 3 doc examples by 1 line each, as
`bevy_input` already has dependencies on everything needed for those
tests and doctests to work.
Add `bevy_reflect`'s "smol_str" feature to `bevy_input`'s dependency
list as it needs it to actually compile.
# Objective
- Resolves#10913.
- Extend `Touches` with methods that are implemented on `ButtonInput`.
## Solution
- Add function `clear_just_pressed` that clears the `just_pressed` state
of the touch input.
- Add function `clear_just_released` that clears the `just_released`
state of the touch input.
- Add function `clear_just_canceled` that clears the `just_canceled`
state of the touch input.
- Add function `release` that changes state of the touch input from
`pressed` to `just_released`.
- Add function `release_all` that changes state of every touch input
from `pressed` to `just_released`
- Add function `clear` that clears `just_pressed`, `just_released` and
`just_canceled` data for every input.
- Add function `reset_all` that clears `pressed`, `just_pressed`,
`just_released` and `just_canceled` data for every input.
- Add tests for functions above.
# Objective
If you have multiple windows, there is no way to determine which window
a `TouchInput` event applies to. This fixes that.
## Solution
- Add the window entity directly to `TouchInput`, just like the other
input events.
- Fixes#6011.
## Migration Guide
+ Add a `window` field when constructing or destructuring a `TouchInput`
struct.
# Objective
There are a lot of doctests that are `ignore`d for no documented reason.
And that should be fixed.
## Solution
I searched the bevy repo with the regex ` ```[a-z,]*ignore ` in order to
find all `ignore`d doctests. For each one of the `ignore`d doctests, I
did the following steps:
1. Attempt to remove the `ignored` attribute while still passing the
test. I did this by adding hidden dummy structs and imports.
2. If step 1 doesn't work, attempt to replace the `ignored` attribute
with the `no_run` attribute while still passing the test.
3. If step 2 doesn't work, keep the `ignored` attribute but add
documentation for why the `ignored` attribute was added.

# Objective
- Update winit dependency to 0.29
## Changelog
### KeyCode changes
- Removed `ScanCode`, as it was [replaced by
KeyCode](https://github.com/rust-windowing/winit/blob/master/CHANGELOG.md#0292).
- `ReceivedCharacter.char` is now a `SmolStr`, [relevant
doc](https://docs.rs/winit/latest/winit/event/struct.KeyEvent.html#structfield.text).
- Changed most `KeyCode` values, and added more.
KeyCode has changed meaning. With this PR, it refers to physical
position on keyboard rather than the printed letter on keyboard keys.
In practice this means:
- On QWERTY keyboard layouts, nothing changes
- On any other keyboard layout, `KeyCode` no longer reflects the label
on key.
- This is "good". In bevy 0.12, when you used WASD for movement, users
with non-QWERTY keyboards couldn't play your game! This was especially
bad for non-latin keyboards. Now, WASD represents the physical keys. A
French player will press the ZQSD keys, which are near each other,
Kyrgyz players will use "Цфыв".
- This is "bad" as well. You can't know in advance what the label of the
key for input is. Your UI says "press WASD to move", even if in reality,
they should be pressing "ZQSD" or "Цфыв". You also no longer can use
`KeyCode` for text inputs. In any case, it was a pretty bad API for text
input. You should use `ReceivedCharacter` now instead.
### Other changes
- Use `web-time` rather than `instant` crate.
(https://github.com/rust-windowing/winit/pull/2836)
- winit did split `run_return` in `run_onDemand` and `pump_events`, I
did the same change in bevy_winit and used `pump_events`.
- Removed `return_from_run` from `WinitSettings` as `winit::run` now
returns on supported platforms.
- I left the example "return_after_run" as I think it's still useful.
- This winit change is done partly to allow to create a new window after
quitting all windows: https://github.com/emilk/egui/issues/1918 ; this
PR doesn't address.
- added `width` and `height` properties in the `canvas` from wasm
example
(https://github.com/bevyengine/bevy/pull/10702#discussion_r1420567168)
## Known regressions (important follow ups?)
- Provide an API for reacting when a specific key from current layout
was released.
- possible solutions: use winit::Key from winit::KeyEvent ; mapping
between KeyCode and Key ; or .
- We don't receive characters through alt+numpad (e.g. alt + 151 = "ù")
anymore ; reproduced on winit example "ime". maybe related to
https://github.com/rust-windowing/winit/issues/2945
- (windows) Window content doesn't refresh at all when resizing. By
reading https://github.com/rust-windowing/winit/issues/2900 ; I suspect
we should just fire a `window.request_redraw();` from `AboutToWait`, and
handle actual redrawing within `RedrawRequested`. I'm not sure how to
move all that code so I'd appreciate it to be a follow up.
- (windows) unreleased winit fix for using set_control_flow in
AboutToWait https://github.com/rust-windowing/winit/issues/3215 ; ⚠️ I'm
not sure what the implications are, but that feels bad 🤔
## Follow up
I'd like to avoid bloating this PR, here are a few follow up tasks
worthy of a separate PR, or new issue to track them once this PR is
closed, as they would either complicate reviews, or at risk of being
controversial:
- remove CanvasParentResizePlugin
(https://github.com/bevyengine/bevy/pull/10702#discussion_r1417068856)
- avoid mentionning explicitly winit in docs from bevy_window ?
- NamedKey integration on bevy_input:
https://github.com/rust-windowing/winit/pull/3143 introduced a new
NamedKey variant. I implemented it only on the converters but we'd
benefit making the same changes to bevy_input.
- Add more info in KeyboardInput
https://github.com/bevyengine/bevy/pull/10702#pullrequestreview-1748336313
- https://github.com/bevyengine/bevy/pull/9905 added a workaround on a
bug allegedly fixed by winit 0.29. We should check if it's still
necessary.
- update to raw_window_handle 0.6
- blocked by wgpu
- Rename `KeyCode` to `PhysicalKeyCode`
https://github.com/bevyengine/bevy/pull/10702#discussion_r1404595015
- remove `instant` dependency, [replaced
by](https://github.com/rust-windowing/winit/pull/2836) `web_time`), we'd
need to update to :
- fastrand >= 2.0
- [`async-executor`](https://github.com/smol-rs/async-executor) >= 1.7
- [`futures-lite`](https://github.com/smol-rs/futures-lite) >= 2.0
- Verify license, see
[discussion](https://github.com/bevyengine/bevy/pull/8745#discussion_r1402439800)
- we might be missing a short notice or description of changes made
- Consider using https://github.com/rust-windowing/cursor-icon directly
rather than vendoring it in bevy.
- investigate [this
unwrap](https://github.com/bevyengine/bevy/pull/8745#discussion_r1387044986)
(`winit_window.canvas().unwrap();`)
- Use more good things about winit's update
- https://github.com/bevyengine/bevy/pull/10689#issuecomment-1823560428
## Migration Guide
This PR should have one.
# Objective
- Provide way to check whether multiple inputs are pressed.
## Solution
- Add `all_pressed` method that checks if all inputs are currently being
pressed.
# Objective
- Resolves#10853
## Solution
- ~~Changed the name of `Input` struct to `PressableInput`.~~
- Changed the name of `Input` struct to `ButtonInput`.
## Migration Guide
- Breaking Change: Users need to rename `Input` to `ButtonInput` in
their projects.
# Objective
- Shorten paths by removing unnecessary prefixes
## Solution
- Remove the prefixes from many paths which do not need them. Finding
the paths was done automatically using built-in refactoring tools in
Jetbrains RustRover.
# Objective
- Standardize fmt for toml files
## Solution
- Add [taplo](https://taplo.tamasfe.dev/) to CI (check for fmt and diff
for toml files), for context taplo is used by the most popular extension
in VScode [Even Better
TOML](https://marketplace.visualstudio.com/items?itemName=tamasfe.even-better-toml
- Add contribution section to explain toml fmt with taplo.
Now to pass CI you need to run `taplo fmt --option indent_string=" "` or
if you use vscode have the `Even Better TOML` extension with 4 spaces
for indent

# 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 => {}
}
```

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.

# 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.
