# Objective
PR #17225 allowed for sprite picking to be opt-in. After some
discussion, it was agreed that `PickingBehavior` should be used to
opt-in to sprite picking behavior for entities. This leads to
`PickingBehavior` having two purposes: mark an entity for use in a
backend, and describe how it should be picked. Discussion led to the
name `Pickable`making more sense (also: this is what the component was
named before upstreaming).
A follow-up pass will be made after this PR to unify backends.
## Solution
Replace all instances of `PickingBehavior` and `picking_behavior` with
`Pickable` and `pickable`, respectively.
## Testing
CI
## Migration Guide
Change all instances of `PickingBehavior` to `Pickable`.
# Objective
Fixes#16903.
## Solution
- Make sprite picking opt-in by requiring a new `SpritePickingCamera`
component for cameras and usage of a new `Pickable` component for
entities.
- Update the `sprite_picking` example to reflect these changes.
- Some reflection cleanup (I hope that's ok).
## Testing
Ran the `sprite_picking` example
## Open Questions
<del>
<ul>
<li>Is the name `SpritePickable` appropriate?</li>
<li>Should `SpritePickable` be in `bevy_sprite::prelude?</li>
</ul>
</del>
## Migration Guide
The sprite picking backend is now strictly opt-in using the
`SpritePickingCamera` and `Pickable` components. You should add the
`Pickable` component any entities that you want sprite picking to be
enabled for, and mark their respective cameras with
`SpritePickingCamera`.
# Objective
Many instances of `clippy::too_many_arguments` linting happen to be on
systems - functions which we don't call manually, and thus there's not
much reason to worry about the argument count.
## Solution
Allow `clippy::too_many_arguments` globally, and remove all lint
attributes related to it.
# Objective
- Allow other crates to use `TextureAtlas` and friends without needing
to depend on `bevy_sprite`.
- Specifically, this allows adding `TextureAtlas` support to custom
cursors in https://github.com/bevyengine/bevy/pull/17121 by allowing
`bevy_winit` to depend on `bevy_image` instead of `bevy_sprite` which is
a [non-starter].
[non-starter]:
https://github.com/bevyengine/bevy/pull/17121#discussion_r1904955083
## Solution
- Move `TextureAtlas`, `TextureAtlasBuilder`, `TextureAtlasSources`,
`TextureAtlasLayout` and `DynamicTextureAtlasBuilder` into `bevy_image`.
- Add a new plugin to `bevy_image` named `TextureAtlasPlugin` which
allows us to register `TextureAtlas` and `TextureAtlasLayout` which was
previously done in `SpritePlugin`. Since `SpritePlugin` did the
registration previously, we just need to make it add
`TextureAtlasPlugin`.
## Testing
- CI builds it.
- I also ran multiple examples which hopefully covered any issues:
```
$ cargo run --example sprite
$ cargo run --example text
$ cargo run --example ui_texture_atlas
$ cargo run --example sprite_animation
$ cargo run --example sprite_sheet
$ cargo run --example sprite_picking
```
---
## Migration Guide
The following types have been moved from `bevy_sprite` to `bevy_image`:
`TextureAtlas`, `TextureAtlasBuilder`, `TextureAtlasSources`,
`TextureAtlasLayout` and `DynamicTextureAtlasBuilder`.
If you are using the `bevy` crate, and were importing these types
directly (e.g. before `use bevy::sprite::TextureAtlas`), be sure to
update your import paths (e.g. after `use bevy::image::TextureAtlas`)
If you are using the `bevy` prelude to import these types (e.g. `use
bevy::prelude::*`), you don't need to change anything.
If you are using the `bevy_sprite` subcrate, be sure to add `bevy_image`
as a dependency if you do not already have it, and be sure to update
your import paths.
I broke the commit history on the other one,
https://github.com/bevyengine/bevy/pull/17160. Woops.
# Objective
- https://github.com/bevyengine/bevy/issues/17111
## Solution
Set the `clippy::allow_attributes` and
`clippy::allow_attributes_without_reason` lints to `deny`, and bring
`bevy_sprite` in line with the new restrictions.
## Testing
`cargo clippy` and `cargo test --package bevy_sprite` were run, and no
errors were encountered.
# Objective
Optimization for sprite picking
## Solution
Use `radsort` for the sort.
We already have `radsort` in tree for sorting various phase items
(including `Transparent2d` / sprites). It's a stable parallel radix
sort.
## Testing
Tested on an M1 Max.
`cargo run --example sprite_picking`
`cargo run --example bevymark --release --features=trace,trace_tracy --
--waves 100 --per-wave 1000 --benchmark`

# Objective
Use the latest version of `typos` and fix the typos that it now detects
# Additional Info
By the way, `typos` has a "low priority typo suggestions issue" where we
can throw typos we find that `typos` doesn't catch.
(This link may go stale) https://github.com/crate-ci/typos/issues/1200
# Objective
- Fixes https://github.com/bevyengine/bevy/issues/16556
- Closes https://github.com/bevyengine/bevy/issues/11807
## Solution
- Simplify custom projections by using a single source of truth -
`Projection`, removing all existing generic systems and types.
- Existing perspective and orthographic structs are no longer components
- I could dissolve these to simplify further, but keeping them around
was the fast way to implement this.
- Instead of generics, introduce a third variant, with a trait object.
- Do an object safety dance with an intermediate trait to allow cloning
boxed camera projections. This is a normal rust polymorphism papercut.
You can do this with a crate but a manual impl is short and sweet.
## Testing
- Added a custom projection example
---
## Showcase
- Custom projections and projection handling has been simplified.
- Projection systems are no longer generic, with the potential for many
different projection components on the same camera.
- Instead `Projection` is now the single source of truth for camera
projections, and is the only projection component.
- Custom projections are still supported, and can be constructed with
`Projection::custom()`.
## Migration Guide
- `PerspectiveProjection` and `OrthographicProjection` are no longer
components. Use `Projection` instead.
- Custom projections should no longer be inserted as a component.
Instead, simply set the custom projection as a value of `Projection`
with `Projection::custom()`.
# Objective
- Allow bevy_sprite_picking backend to pass through transparent sections
of the sprite.
- Fixes#14929
## Solution
- After sprite picking detects the cursor is within a sprites rect,
check the pixel at that location on the texture and check that it meets
an optional transparency cutoff. Change originally created for
mod_picking on bevy 0.14
(https://github.com/aevyrie/bevy_mod_picking/pull/373)
## Testing
- Ran Sprite Picking example to check it was working both with
transparency enabled and disabled
- ModPicking version is currently in use in my own isometric game where
this has been an extremely noticeable issue
## Showcase
## Migration Guide
Sprite picking now ignores transparent regions (with an alpha value less
than or equal to 0.1). To configure this, modify the
`SpriteBackendSettings` resource.

# Objective
- When picking sprites, the pointer is offset from the mouse, causing
you to pick sprites you're not mousing over!
## Solution
- Shift over the cursor by the minimum of the viewport.
## Testing
- I was already using the bevy_mod_picking PR for my project, so it
seems to work!
- I tested this on the sprite_example (making the camera only render to
part of the viewport), and it also works there.
## Notes
- This is just https://github.com/aevyrie/bevy_mod_picking/pull/365 but
in Bevy form.
- We don't need to renormalize the viewport in any way since the
viewport is specified in pixels, so all that matters is that the origin
is correct.

# Objective
Fixes#15940
## Solution
Remove the `pub use` and fix the compile errors.
Make `bevy_image` available as `bevy::image`.
## Testing
Feature Frenzy would be good here! Maybe I'll learn how to use it if I
have some time this weekend, or maybe a reviewer can use it.
## Migration Guide
Use `bevy_image` instead of `bevy_render::texture` items.

# Objective
- `MeshPickingBackend` and `SpritePickingBackend` do not have the
`Plugin` suffix
- `DefaultPickingPlugins` is masquerading as a `Plugin` when in reality
it should be a `PluginGroup`
- Fixes#16081.
## Solution
- Rename some structures:
|Original Name|New Name|
|-|-|
|`MeshPickingBackend`|`MeshPickingPlugin`|
|`MeshPickingBackendSettings`|`MeshPickingSettings`|
|`SpritePickingBackend`|`SpritePickingPlugin`|
|`UiPickingBackendPlugin`|`UiPickingPlugin`|
- Make `DefaultPickingPlugins` a `PluginGroup`.
- Because `DefaultPickingPlugins` is within the `DefaultPlugins` plugin
group, I also added support for nested plugin groups to the
`plugin_group!` macro.
## Testing
- I used ripgrep to ensure all references were properly renamed.
- For the `plugin_group!` macro, I used `cargo expand` to manually
inspect the expansion of `DefaultPlugins`.
---
## Migration Guide
> [!NOTE]
>
> All 3 of the changed structures were added after 0.14, so this does
not need to be included in the 0.14 to 0.15 migration guide.
- `MeshPickingBackend` is now named `MeshPickingPlugin`.
- `MeshPickingBackendSettings` is now named `MeshPickingSettings`.
- `SpritePickingBackend` is now named `SpritePickingPlugin`.
- `UiPickingBackendPlugin` is now named `UiPickingPlugin`.
- `DefaultPickingPlugins` is now a a `PluginGroup` instead of a
`Plugin`.
# Objective
- We don't have to `collect` and `sort` invisible sprites in
`sprite_picking` system.
## Solution
- Filter by `ViewVisibility::get()` earlier
## Testing
- `sprite_picking` example still works.
# Objective
Continue migration of bevy APIs to required components, following
guidance of https://hackmd.io/@bevy/required_components/
## Solution
- Make `Sprite` require `Transform` and `Visibility` and
`SyncToRenderWorld`
- move image and texture atlas handles into `Sprite`
- deprecate `SpriteBundle`
- remove engine uses of `SpriteBundle`
## Testing
ran cargo tests on bevy_sprite and tested several sprite examples.
---
## Migration Guide
Replace all uses of `SpriteBundle` with `Sprite`. There are several new
convenience constructors: `Sprite::from_image`,
`Sprite::from_atlas_image`, `Sprite::from_color`.
WARNING: use of `Handle<Image>` and `TextureAtlas` as components on
sprite entities will NO LONGER WORK. Use the fields on `Sprite` instead.
I would have removed the `Component` impls from `TextureAtlas` and
`Handle<Image>` except it is still used within ui. We should fix this
moving forward with the migration.
# Objective
- Rename `Pickable` to `PickingBehavior` to counter the easily-made
assumption that the component is required. It is optional
- Fix and clarify documentation
- The docs in `crates/bevy_ui/src/picking_backend.rs` were incorrect
about the necessity of `Pickable`
- Plus two minor code quality changes in this commit
(7c2e75f48d)
Closes#15632
# Objective
- Fix panic when atlas index is out of bounds
- Took the chance to clean it up a bit
## Solution
- Use texture dimensions like rendering pipeline. Dropped atlas layouts
and indexes out of bounds are shown as a sprite.
## Testing
Used sprite_picking example, drop layout and/or use indexes out of
bounds.
# 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.

# Objective
Fixes#15258
## Solution
If my understanding is correct, sprites with NaN anywhere in their
transform won't even get onto the screen, so should not generate pick
events. This PR filters sprites with NaN in their transforms before
sorting by depth, then uses `FloatOrd` to simplify the comparison. Since
we're guaranteed to not have NaN values, it's technically unnecessary,
and we could instead sort with `a.partial_cmp(&b).unwrap()`, or even
`unwrap_unchecked()`.
## Testing
I ran the picking example to ensure Z sorting was working as intended.
# Objective
- Fixes https://github.com/bevyengine/bevy/issues/14593.
## Solution
- Add `ViewportConversionError` and return it from viewport conversion
methods on Camera.
## Testing
- I successfully compiled and ran all changed examples.
## Migration Guide
The following methods on `Camera` now return a `Result` instead of an
`Option` so that they can provide more information about failures:
- `world_to_viewport`
- `world_to_viewport_with_depth`
- `viewport_to_world`
- `viewport_to_world_2d`
Call `.ok()` on the `Result` to turn it back into an `Option`, or handle
the `Result` directly.

# Objective
Add `bevy_picking` sprite backend as part of the `bevy_mod_picking`
upstreamening (#12365).
## Solution
More or less a copy/paste from `bevy_mod_picking`, with the changes
[here](https://github.com/aevyrie/bevy_mod_picking/pull/354). I'm
putting that link here since those changes haven't yet made it through
review, so should probably be reviewed on their own.
## Testing
I couldn't find any sprite-backend-specific tests in `bevy_mod_picking`
and unfortunately I'm not familiar enough with Bevy's testing patterns
to write tests for code that relies on windowing and input. I'm willing
to break the pointer hit system into testable blocks and add some more
modular tests if that's deemed important enough to block, otherwise I
can open an issue for adding tests as follow-up.
## Follow-up work
- More docs/tests
- Ignore pick events on transparent sprite pixels with potential opt-out
