# Objective
- Implement a subset of
https://github.com/bevyengine/rfcs/blob/main/rfcs/12-primitive-shapes.md#feature-name-primitive-shapes
## Solution
- Define a very basic set of primitives in bevy_math
- Assume a 0,0,0 origin for most shapes
- Use radius and half extents to avoid unnecessary computational
overhead wherever they get used
- Provide both Boxed and const generics variants for shapes with
variable sizes
- Boxed is useful if a 3rd party crate wants to use something like
enum-dispatch for all supported primitives
- Const generics is useful when just working on a single primitive, as
it causes no allocs
#### Some discrepancies from the RFC:
- Box was changed to Cuboid, because Box is already used for an alloc
type
- Skipped Cone because it's unclear where the origin should be for
different uses
- Skipped Wedge because it's too niche for an initial PR (we also don't
implement Torus, Pyramid or a Death Star (there's an SDF for that!))
- Skipped Frustum because while it would be a useful math type, it's not
really a common primitive
- Skipped Triangle3d and Quad3d because those are just rotated 2D shapes
## Future steps
- Add more primitives
- Add helper methods to make primitives easier to construct (especially
when half extents are involved)
- Add methods to calculate AABBs for primitives (useful for physics, BVH
construction, for the mesh AABBs, etc)
- Add wrappers for common and cheap operations, like extruding 2D shapes
and translating them
- Use the primitives to generate meshes
- Provide signed distance functions and gradients for primitives (maybe)

## Migration Guide
`Color::from(Vec4)` is now `Color::rgba_from_array(impl Into<[f32; 4]>)`
`Vec4::from(Color)` is now `Color::rgba_to_vec4(&self)`
Before:
```rust
let color_vec4 = Vec4::new(0.5, 0.5, 0.5);
let color_from_vec4 = Color::from(color_vec4);
let color_array = [0.5, 0.5, 0.5];
let color_from_array = Color::from(color_array);
```
After:
```rust
let color_vec4 = Vec4::new(0.5, 0.5, 0.5);
let color_from_vec4 = Color::rgba_from_array(color_vec4);
let color_array = [0.5, 0.5, 0.5];
let color_from_array = Color::rgba_from_array(color_array);
```

# Objective
- When compiling bevy for both singlethreaded and multithreaded contexts
and using `Task` directly, you can run into errors where you expect a
`Task` to be returned but `FakeTask` is instead. Due to `FakeTask` being
private the only solution is to ignore the return at all however because
it *is* returned that isn't totally clear. The error is confusing and
doesn't provide a solution or help figuring it out.
## Solution
- Made `FakeTask` public and added brief documentation providing a use
(none) that helps guide usage (no usage) of FakeTask.
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
- Add an arrow gizmo as suggested by #9400
## Solution

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

# Objective
Allows chained systems taking an `In<_>` input parameter to be run as
one-shot systems. This API was mentioned in #8963.
In addition, `run_system(_with_input)` returns the system output, for
any `'static` output type.
## Solution
A new function, `World::run_system_with_input` allows a `SystemId<I, O>`
to be run by providing an `I` value as input and producing `O` as an
output.
`SystemId<I, O>` is now generic over the input type `I` and output type
`O`, along with the related functions and types `RegisteredSystem`,
`RemovedSystem`, `register_system`, `remove_system`, and
`RegisteredSystemError`. These default to `()`, preserving the existing
API, for all of the public types.
---
## Changelog
- Added `World::run_system_with_input` function to allow one-shot
systems that take `In<_>` input parameters
- Changed `World::run_system` and `World::register_system` to support
systems with return types beyond `()`
- Added `Commands::run_system_with_input` command that schedules a
one-shot system with an `In<_>` input parameter
# Objective
- Ensure ExtendedMaterial can be referenced in bevy_egui_inspector
correctly
## Solution
Add a more manual `TypePath` implementation to work around bugs in the
derive macro.
# Objective
Make sure a camera which has had its render target changed recomputes
its info.
On main, the following is possible:
- System A has an inactive camera with render target set to the default
`Image` (i.e. white 1x1 rgba texture)
Later:
- System B sets the same camera active and sets the `camera.target` to a
newly created `Image`
**Bug**: Since `camera_system` only checks `Modified` and not `Added`
events, the size of the render target is not recomputed, which means the
camera will render with 1x1 size even though the new target is an
entirely different size.
## Solution
- Ensure `camera_system` checks `Added` image assets events
## Changelog
### Fixed
- Cameras which have their render targets changed to a newly created
target with a different size than the previous target will now render
properly

# Objective
The quality of Bevy's text rendering can vary wildly depending on the
font, font size, pixel alignment and scale factor.
But this situation can be improved dramatically with some small
adjustments.
## Solution
* Text node positions are rounded to the nearest physical pixel before
rendering.
* Each glyph texture has a 1-pixel wide transparent border added along
its edges.
This means font atlases will use more memory because of the extra pixel
of padding for each glyph but it's more than worth it I think (although
glyph size is increased by 2 pixels on both axes, the net increase is 1
pixel as the font texture atlas's padding has been removed).
## Results
Screenshots are from the 'ui' example with a scale factor of 1.5.
Things can get much uglier with the right font and worst scale
factor<sup>tm</sup>.

Alternative to #10465
## Solution
`load_untyped_async` / `load_internal` currently has a bug. In
`load_untyped_async`, we pass None into `load_internal` for the
`UntypedHandle` of the labeled asset path. This results in a call to
`get_or_create_path_handle_untyped` with `loader.asset_type_id()`
This is a new code path that wasn't hit prior to the newly added
`load_untyped` because `load_untyped_async` was a private method only
used in the context of the `load_folder` impl (which doesn't have
labels)
The fix required some refactoring to catch that case and defer handle
retrieval. I have also made `load_untyped_async` public as it is now
"ready for public use" and unlocks new scenarios.
# Objective
- 2d materials have subtle differences with 3d materials that aren't
obvious to beginners
## Solution
- Add an example that shows how to make a 2d material
# Objective
Currently, if a large amount of inactive cameras are spawned, they will
immensely slow down performance.
This can be reproduced by adding
```rust
let default_image = images.add(default());
for _ in 0..10000 {
commands.spawn(Camera3dBundle {
camera: Camera {
is_active: false,
target: RenderTarget::Image(default_image.clone()),
..default()
},
..default()
});
}
```
to for example `3d_shapes`.
Using `tracy`, it's clear that preparing view bind groups for all
cameras is still happening.
Also, visibility checks on the extracted views from inactive cameras
also take place.
## Performance gains
The following `tracy` comparisons show the effect of skipping this
unneeded work.
Yellow is Bevy main, red is with the fix.
### Visibility checks
### Bind group preparation
## Solution
- Check if the cameras are inactive in the appropriate places, and if so
skip them
## Changelog
### Changed
- Do not extract views from inactive cameras or check visiblity from
their extracted views

(This is my first PR here, so I've probably missed some things. Please
let me know what else I should do to help you as a reviewer!)
# Objective
Due to https://github.com/rust-lang/rust/issues/117800, the `derive`'d
`PartialEq::eq` on `Entity` isn't as good as it could be. Since that's
used in hashtable lookup, let's improve it.
## Solution
The derived `PartialEq::eq` short-circuits if the generation doesn't
match. However, having a branch there is sub-optimal, especially on
64-bit systems like x64 that could just load the whole `Entity` in one
load anyway.
Due to complications around `poison` in LLVM and the exact details of
what unsafe code is allowed to do with reference in Rust
(https://github.com/rust-lang/unsafe-code-guidelines/issues/346), LLVM
isn't allowed to completely remove the short-circuiting. `&Entity` is
marked `dereferencable(8)` so LLVM knows it's allowed to *load* all 8
bytes -- and does so -- but it has to assume that the `index` might be
undef/poison if the `generation` doesn't match, and thus while it finds
a way to do it without needing a branch, it has to do something slightly
more complicated than optimal to combine the results. (LLVM is allowed
to change non-short-circuiting code to use branches, but not the other
way around.)
Here's a link showing the codegen today:
<https://rust.godbolt.org/z/9WzjxrY7c>
```rust
#[no_mangle]
pub fn demo_eq_ref(a: &Entity, b: &Entity) -> bool {
a == b
}
```
ends up generating the following assembly:
```asm
demo_eq_ref:
movq xmm0, qword ptr [rdi]
movq xmm1, qword ptr [rsi]
pcmpeqd xmm1, xmm0
pshufd xmm0, xmm1, 80
movmskpd eax, xmm0
cmp eax, 3
sete al
ret
```
(It's usually not this bad in real uses after inlining and LTO, but it
makes a strong demo.)
This PR manually implements `PartialEq::eq` *without* short-circuiting,
and because that tells LLVM that neither the generations nor the index
can be poison, it doesn't need to be so careful and can generate the
"just compare the two 64-bit values" code you'd have probably already
expected:
```asm
demo_eq_ref:
mov rax, qword ptr [rsi]
cmp qword ptr [rdi], rax
sete al
ret
```
Since this doesn't change the representation of `Entity`, if it's
instead passed by *value*, then each `Entity` is two `u32` registers,
and the old and the new code do exactly the same thing. (Other
approaches, like changing `Entity` to be `[u32; 2]` or `u64`, affect
this case.)
This should hopefully merge easily with changes like
https://github.com/bevyengine/bevy/pull/9907 that also want to change
`Entity`.
## Benchmarks
I'm not super-confident that I got my machine fully consistent for
benchmarking, but whether I run the old or the new one first I get
reasonably consistent results.
Here's a fairly typical example of the benchmarks I added in this PR:
Building the sets seems to be basically the same. It's usually reported
as noise, but sometimes I see a few percent slower or faster.
But lookup hits in particular -- since a hit checks that the key is
equal -- consistently shows around 10% improvement.
`cargo run --example many_cubes --features bevy/trace_tracy --release --
--benchmark` showed as slightly faster with this change, though if I had
to bet I'd probably say it's more noise than meaningful (but at least
it's not worse either):
This is my first PR here -- and my first time running Tracy -- so please
let me know what else I should run, or run things on your own more
reliable machines to double-check.
---
## Changelog
(probably not worth including)
Changed: micro-optimized `Entity::eq` to help LLVM slightly.
## Migration Guide
(I really hope nobody was using this on uninitialized entities where
sufficiently tortured `unsafe` could could technically notice that this
has changed.)
# Objective
After #9002, it seems that "single shot" animations were broken. When
completing, they would reset to their initial value. Which is generally
not what you want.
- Fixes#10480
## Solution
Avoid `%`-ing the animation after the number of completions exceeds the
specified one. Instead, we early-return. This is also true when the
player is playing in reverse.
---
## Changelog
- Avoid resetting animations after `Repeat::Never` animation completion.
# Objective
Fixes an issue where Bevy will look for `.meta` files in the root of the
server instead of `imported_assets/Default` on the web.
## Solution
`self.root_path.join` was seemingly forgotten in the `read_meta`
function on `HttpWasmAssetReader`, though it was included in the `read`
function. This PR simply adds the missing function call.
# Objective
* In Bevy 0.11 asset loaders used `anyhow::Error` for returning errors.
In Bevy 0.12 `AssetLoader` (and `AssetSaver`) have associated `Error`
type. Unfortunately it's type bounds does not allow `anyhow::Error` to
be used despite migration guide claiming otherwise. This makes migration
to 0.12 more challenging. Solve this by changing type bounds for
associated `Error` type.
* Fix#10350
## Solution
Change associated `Error` type bounds to require `Into<Box<dyn
std::error::Error + Send + Sync + 'static>>` to be implemented instead
of `std::error::Error + Send + Sync + 'static`. Both `anyhow::Error` and
errors generated by `thiserror` seems to be fine with such type bound.

### Fixed
* Fixed compatibility with `anyhow::Error` in `AssetLoader` and
`AssetSaver` associated `Error` type
# Objective
Fixes#10439
`Timer::percent()` and `Timer::percent_left()` return values in the
range of 0.0 to 1.0, even though their names contain "percent".
These functions should be renamed for clarity.
## Solution
- Rename `Timer::percent()` to `Timer::fraction()`
- Rename `Timer::percent_left()` to `Timer::fraction_remaining()`
---
## Changelog
### Changed
- Renamed `Timer::percent()` to `Timer::fraction()`
- Renamed `Timer::percent_left()` to `Timer::fraction_remaining()`
## Migration Guide
- `Timer::percent()` has been renamed to `Timer::fraction()`
- `Timer::percent_left()` has been renamed to
`Timer::fraction_remaining()`
# Objective
This is similar to #10439.
`Time::<Fixed>::overstep_percentage()` and
`Time::<Fixed>::overstep_percentage_f64()` returns values from 0.0 to
1.0, but their names use the word "percentage". These function names
make it easy to misunderstand that they return values from 0.0 to 100.0.
To avoid confusion, these functions should be renamed to
"`overstep_fraction(_f64)`".
## Solution
Rename them.
---
## Changelog
### Changed
- Renamed `Time::<Fixed>::overstep_percentage()` to
`Time::<Fixed>::overstep_fraction()`
- Renamed `Time::<Fixed>::overstep_percentage_f64()` to
`Time::<Fixed>::overstep_fraction_f64()`
## Migration Guide

# Objective
Hot reloading shader imports on windows is currently broken due to
inconsistent `/` and `\` usage ('/` is used in the user facing APIs and
`\` is produced by notify-rs (and likely other OS apis).

Standardize import paths when loading a `Shader`. The correct long term
fix is to standardize AssetPath on `/`-only, but this is the right scope
of fix for a patch release.

# Objective
Related to #10472.
Not having a hardcoded scale factor makes comparing results from these
stress tests difficult.
Contributors using high dpi screens may be rendering 4x as many pixels
as others (or more). Stress tests may have different behavior when moved
from one monitor in a dual setup to another. At very high resolutions,
different parts of the engine / hardware are being stressed.
1080p is also a far more common resolution for gaming.
## Solution
Use a consistent 1080p with `scale_factor_override: 1.0` everywhere.
In #9903, this sort of change was added specifically to `bevymark` and
`many_cubes` but it makes sense to do it everywhere.
## Discussion
- Maybe we should have a command line option, environment variable, or
`CI_TESTING_CONFIG` option for 1080p / 1440p / 4k.
- Will these look odd (small text?) when screenshotted and shown in the
example showcase? The aspect ratio is the same, but they will be
downscaled from 1080p instead of ~720p.
- Maybe there are other window properties that should be consistent
across stress tests. e.g. `resizable: false`.
- Should we add a `stress_test_window(title)` helper or something?
- Bevymark (pre-10472) was intentionally 800x600 to match "bunnymark", I
believe. I don't personally think this is very important.
# Objective
- `CommandQueue::apply` calculates the address of the end of the
internal buffer as a `usize` rather than as a pointer, requiring two
casts of `cursor` to `usize`. Casting pointers to integers is generally
discouraged and may also prevent optimizations. It's also unnecessary
here.
## Solution
- Calculate the end address as a pointer rather than a `usize`.
Small note:
A trivial translation of the old code to use pointers would have
computed `end_addr` as `cursor.add(self.bytes.len())`, which is not
wrong but is an additional `unsafe` operation that also needs to be
properly documented and proven correct. However this operation is
already implemented in the form of the safe `as_mut_ptr_range`, so I
just used that.
# Objective
- The docs on `AssetPath::try_parse` say that it will return an error
when the string is malformed, but it actually just `.unwrap()`s the
result.
## Solution
- Use `?` instead of unwrapping the result.
# Objective
Calling `RenderDevice::poll` requires an instance of `wgpu::Maintain`,
but the type was not reexported by bevy. Working around it requires
adding a dependency on `wgpu`, since bevy does not reexport the `wgpu`
crate as a whole anywhere.
## Solution
Reexport `wgpu::Maintain` in `render_resource`, where the other wgpu
types are reexported.
# Objective
There is an if statement checking if a node is present in a graph
moments after it explicitly being added.
Unless the edge function has super weird side effects and the tests
don't pass, this is unnecessary.
## Solution
Removed it
# Objective
- Allow registration of one-shot systems when those systems have already
been `Box`ed.
- Needed for `bevy_eventlisteners` which allows adding event listeners
with callbacks in normal systems. The current one shot system
implementation requires systems be registered from an exclusive system,
and that those systems be passed in as types that implement
`IntoSystem`. However, the eventlistener callback crate allows users to
define their callbacks in normal systems, by boxing the system and
deferring initialization to an exclusive system.
## Solution
- Separate the registration of the system from the boxing of the system.
This is non-breaking, and adds a new method.
---
## Changelog
- Added `World::register_boxed_system` to allow registration of
already-boxed one shot systems.

# Objective
Had an issue where I had `VisibilityBundle` inside a bundle that
implements `Clone`, but since `VisibilityBundle` doesn't implement
`Clone` that wasn't possible. This PR fixes that.
## Solution
Implement `Clone` for `VisibilityBundle` by deriving it. And also
`SpatialBundle` too because why not.
---
## Changelog
- Added implementation for `Clone` on `VisibilityBundle` and
`SpatialBundle`.
# Objective
Fix a shader error that happens when using pbr morph targets.
## Solution
Fix the function name in the `prepass.wgsl` shader, which is incorrectly
prefixed with `morph::` (added in
61bad4eb57 (diff-97e4500f0a36bc6206d7b1490c8dd1a69459ee39dc6822eb9b2f7b160865f49fR42)).
This section of the shader is only enabled when using morph targets, so
it seems like there are no tests / examples using it?
# Objective
- Entities with both a `BackgroundColor` and a
`Handle<CustomUiMaterial>` are extracted by both pipelines and results
in entities being overwritten in the render world
- Fixes#10431
## Solution
- Ignore entities with `BackgroundColor` when extracting ui material
entities, and document that limit
# Objective
- There is a specialized hasher for entities:
[`EntityHashMap`](https://docs.rs/bevy/latest/bevy/utils/type.EntityHashMap.html)
- [`EntityMapper`] currently uses a normal `HashMap<Entity, Entity>`
- Fixes#10391
## Solution
- Replace the normal `HashMap` with the more performant `EntityHashMap`
## Questions
- This does change public API. Should a system be implemented to help
migrate code?
- Perhaps an `impl From<HashMap<K, V, S>> for EntityHashMap<K, V>`
- I updated to docs for each function that I changed, but I may have
missed something
---
## Changelog
- Changed `EntityMapper` to use `EntityHashMap` instead of normal
`HashMap`
## Migration Guide
If you are using the following types, update their listed methods to use
the new `EntityHashMap`. `EntityHashMap` has the same methods as the
normal `HashMap`, so you just need to replace the name.
### `EntityMapper`
- `get_map`
- `get_mut_map`
- `new`
- `world_scope`
### `ReflectMapEntities`
- `map_all_entities`
- `map_entities`
- `write_to_world`
### `InstanceInfo`
- `entity_map`
- This is a property, not a method.
---
This is my first time contributing in a while, and I'm not familiar with
the usage of `EntityMapper`. I changed the type definition and fixed all
errors, but there may have been things I've missed. Please keep an eye
out for me!
