The PR is in a reviewable state now in the sense that the basic
implementations are there. There are still some ToDos that I'm aware of:
- [x] docs for all the new structs and traits
- [x] implement `Default` and derive other useful traits for the new
structs
- [x] Take a look at the notes again (Do this after a first round of
reviews)
- [x] Take care of the repetition in the circle drawing functions
---
# Objective
- TLDR: This PR enables us to quickly draw all the newly added
primitives from `bevy_math` in immediate mode with gizmos
- Addresses #10571
## Solution
- This implements the first design idea I had that covered everything
that was mentioned in the Issue
https://github.com/bevyengine/bevy/issues/10571#issuecomment-1863646197
---
## Caveats
- I added the `Primitive(2/3)d` impls for `Direction(2/3)d` to make them
work with the current solution. We could impose less strict requirements
for the gizmoable objects and remove the impls afterwards if the
community doesn't like the current approach.
---
## Changelog
- implement capabilities to draw ellipses on the gizmo in general (this
was required to have some code which is able to draw the ellipse
primitive)
- refactored circle drawing code to use the more general ellipse drawing
code to keep code duplication low
- implement `Primitive2d` for `Direction2d` and impl `Primitive3d` for
`Direction3d`
- implement trait to draw primitives with specialized details with
gizmos
- `GizmoPrimitive2d` for all the 2D primitives
- `GizmoPrimitive3d` for all the 3D primitives
- (question while writing this: Does it actually matter if we split this
in 2D and 3D? I guess it could be useful in the future if we do
something based on the main rendering mode even though atm it's kinda
useless)

# Objective
This PR aims to implement multiple configs for gizmos as discussed in
#9187.
## Solution
Configs for the new `GizmoConfigGroup`s are stored in a
`GizmoConfigStore` resource and can be accesses using a type based key
or iterated over. This type based key doubles as a standardized location
where plugin authors can put their own configuration not covered by the
standard `GizmoConfig` struct. For example the `AabbGizmoGroup` has a
default color and toggle to show all AABBs. New configs can be
registered using `app.init_gizmo_group::<T>()` during startup.
When requesting the `Gizmos<T>` system parameter the generic type
determines which config is used. The config structs are available
through the `Gizmos` system parameter allowing for easy access while
drawing your gizmos.
Internally, resources and systems used for rendering (up to an including
the extract system) are generic over the type based key and inserted on
registering a new config.
## Alternatives
The configs could be stored as components on entities with markers which
would make better use of the ECS. I also implemented this approach
([here](https://github.com/jeliag/bevy/tree/gizmo-multiconf-comp)) and
believe that the ergonomic benefits of a central config store outweigh
the decreased use of the ECS.
## Unsafe Code
Implementing system parameter by hand is unsafe but seems to be required
to access the config store once and not on every gizmo draw function
call. This is critical for performance. ~Is there a better way to do
this?~
## Future Work
New gizmos (such as #10038, and ideas from #9400) will require custom
configuration structs. Should there be a new custom config for every
gizmo type, or should we group them together in a common configuration?
(for example `EditorGizmoConfig`, or something more fine-grained)
## Changelog
- Added `GizmoConfigStore` resource and `GizmoConfigGroup` trait
- Added `init_gizmo_group` to `App`
- Added early returns to gizmo drawing increasing performance when
gizmos are disabled
- Changed `GizmoConfig` and aabb gizmos to use new `GizmoConfigStore`
- Changed `Gizmos` system parameter to use type based key to retrieve
config
- Changed resources and systems used for gizmo rendering to be generic
over type based key
- Changed examples (3d_gizmos, 2d_gizmos) to showcase new API
## Migration Guide
- `GizmoConfig` is no longer a resource and has to be accessed through
`GizmoConfigStore` resource. The default config group is
`DefaultGizmoGroup`, but consider using your own custom config group if
applicable.

# 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
- 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
- Add an arrow gizmo as suggested by #9400
## Solution
(excuse my Protomen music)
https://github.com/bevyengine/bevy/assets/14184826/192adf24-079f-4a4b-a17b-091e892974ec
Wasn't horribly hard when i remembered i can change coordinate systems
whenever I want. Gave them four tips (as suggested by @alice-i-cecile in
discord) instead of trying to decide what direction the tips should
point.
Made the tip length default to 1/10 of the arrow's length, which looked
good enough to me. Hard-coded the angle from the body to the tips to 45
degrees.
## Still TODO
- [x] actual doc comments
- [x] doctests
- [x] `ArrowBuilder.with_tip_length()`
---
## Changelog
- Added `gizmos.arrow()` and `gizmos.arrow_2d()`
- Added arrows to `2d_gizmos` and `3d_gizmos` examples

<summary>Performance</summary>
Stress tested using Bevy's recommended optimization settings for the dev
profile with the
following command.
```bash
cargo run --example many_debug_lines \

### TODO
- [ ] Update changelog
- [x] Update performance numbers
- [x] Add credit to PR description
### Future work
- Cache rendering primitives instead of constructing them out of line
segments each frame.
- Support for drawing solid meshes
- Interactions. (See
[bevy_mod_gizmos](https://github.com/LiamGallagher737/bevy_mod_gizmos))
- Fancier line drawing. (See
