Use impl Into<A> for Assets::add (#10878)
# Motivation
When spawning entities into a scene, it is very common to create assets
like meshes and materials and to add them via asset handles. A common
setup might look like this:
```rust
fn setup(
mut commands: Commands,
mut meshes: ResMut<Assets<Mesh>>,
mut materials: ResMut<Assets<StandardMaterial>>,
) {
commands.spawn(PbrBundle {
mesh: meshes.add(Mesh::from(shape::Cube { size: 1.0 })),
material: materials.add(StandardMaterial::from(Color::RED)),
..default()
});
}
```
Let's take a closer look at the part that adds the assets using `add`.
```rust
mesh: meshes.add(Mesh::from(shape::Cube { size: 1.0 })),
material: materials.add(StandardMaterial::from(Color::RED)),
```
Here, "mesh" and "material" are both repeated three times. It's very
explicit, but I find it to be a bit verbose. In addition to being more
code to read and write, the extra characters can sometimes also lead to
the code being formatted to span multiple lines even though the core
task, adding e.g. a primitive mesh, is extremely simple.
A way to address this is by using `.into()`:
```rust
mesh: meshes.add(shape::Cube { size: 1.0 }.into()),
material: materials.add(Color::RED.into()),
```
This is fine, but from the names and the type of `meshes`, we already
know what the type should be. It's very clear that `Cube` should be
turned into a `Mesh` because of the context it's used in. `.into()` is
just seven characters, but it's so common that it quickly adds up and
gets annoying.
It would be nice if you could skip all of the conversion and let Bevy
handle it for you:
```rust
mesh: meshes.add(shape::Cube { size: 1.0 }),
material: materials.add(Color::RED),
```
# Objective
Make adding assets more ergonomic by making `Assets::add` take an `impl
Into<A>` instead of `A`.
## Solution
`Assets::add` now takes an `impl Into<A>` instead of `A`, so e.g. this
works:
```rust
commands.spawn(PbrBundle {
mesh: meshes.add(shape::Cube { size: 1.0 }),
material: materials.add(Color::RED),
..default()
});
```
I also changed all examples to use this API, which increases consistency
as well because `Mesh::from` and `into` were being used arbitrarily even
in the same file. This also gets rid of some lines of code because
formatting is nicer.
---
## Changelog
- `Assets::add` now takes an `impl Into<A>` instead of `A`
- Examples don't use `T::from(K)` or `K.into()` when adding assets
## Migration Guide
Some `into` calls that worked previously might now be broken because of
the new trait bounds. You need to either remove `into` or perform the
conversion explicitly with `from`:
```rust
// Doesn't compile
let mesh_handle = meshes.add(shape::Cube { size: 1.0 }.into()),
// These compile
let mesh_handle = meshes.add(shape::Cube { size: 1.0 }),
let mesh_handle = meshes.add(Mesh::from(shape::Cube { size: 1.0 })),
```
## Concerns
I believe the primary concerns might be:
1. Is this too implicit?
2. Does this increase codegen bloat?
Previously, the two APIs were using `into` or `from`, and now it's
"nothing" or `from`. You could argue that `into` is slightly more
explicit than "nothing" in cases like the earlier examples where a
`Color` gets converted to e.g. a `StandardMaterial`, but I personally
don't think `into` adds much value even in this case, and you could
still see the actual type from the asset type.
As for codegen bloat, I doubt it adds that much, but I'm not very
familiar with the details of codegen. I personally value the user-facing
code reduction and ergonomics improvements that these changes would
provide, but it might be worth checking the other effects in more
detail.
Another slight concern is migration pain; apps might have a ton of
`into` calls that would need to be removed, and it did take me a while
to do so for Bevy itself (maybe around 20-40 minutes). However, I think
the fact that there *are* so many `into` calls just highlights that the
API could be made nicer, and I'd gladly migrate my own projects for it.

Update winit dependency to 0.29 (#10702)
# 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. |

Update color and naming for consistency (#10367)
The `ClearColor` PR was merged before I was quite finished. This fixes a few errors, and addresses Cart's feedback about the pixel perfect example by updating the sprite colors to match the existing bevy bird branding colors.  |

Update default ClearColor to better match Bevy's branding (#10339)
# Objective - Changes the default clear color to match the code block color on Bevy's website. ## Solution - Changed the clear color, updated text in examples to ensure adequate contrast. Inconsistent usage of white text color set to use the default color instead, which is already white. - Additionally, updated the `3d_scene` example to make it look a bit better, and use bevy's branding colors.  |

Deferred Renderer (#9258)
# Objective - Add a [Deferred Renderer](https://en.wikipedia.org/wiki/Deferred_shading) to Bevy. - This allows subsequent passes to access per pixel material information before/during shading. - Accessing this per pixel material information is needed for some features, like GI. It also makes other features (ex. Decals) simpler to implement and/or improves their capability. There are multiple approaches to accomplishing this. The deferred shading approach works well given the limitations of WebGPU and WebGL2. Motivation: [I'm working on a GI solution for Bevy](https://youtu.be/eH1AkL-mwhI) # Solution - The deferred renderer is implemented with a prepass and a deferred lighting pass. - The prepass renders opaque objects into the Gbuffer attachment (`Rgba32Uint`). The PBR shader generates a `PbrInput` in mostly the same way as the forward implementation and then [packs it into the Gbuffer]( |
