# Objective
- Fixes#4996
## Solution
- Panicking on the global task pool is probably bad. This changes the panicking test to use a single threaded stage to run the test instead.
- I checked the other #[should_panic]
- I also added explicit ordering between the transform propagate system and the parent update system. The ambiguous ordering didn't seem to be causing problems, but the tests are probably more correct this way. The plugins that add these systems have an explicit ordering. I can remove this if necessary.
## Note
I don't have a 100% mental model of why panicking is causing intermittent failures. It probably has to do with a task for one of the other tests landing on the panicking thread when it actually panics. Why this causes a problem I'm not sure, but this PR seems to fix things.
## Open questions
- there are some other #[should_panic] tests that run on the task pool in stage.rs. I don't think we restart panicked threads, so this might be killing most of the threads on the pool. But since they're not causing test failures, we should probably decide what to do about that separately. The solution in this PR won't work since those tests are explicitly testing parallelism.
# Objective
- Transform propogation could stack overflow when there was a cycle.
- I think https://github.com/bevyengine/bevy/pull/4203 would use all available memory.
## Solution
- Make sure that the child entity's `Parent`s are their parents.
This is also required for when parallelising, although as noted in the comment, the naïve solution would be UB.
(The best way to fix this would probably be an `&mut UnsafeCell<T>` `WorldQuery`, or wrapper type with the same effect)
### Problem
It currently isn't possible to construct the default value of a reflected type. Because of that, it isn't possible to use `add_component` of `ReflectComponent` to add a new component to an entity because you can't know what the initial value should be.
### Solution
1. add `ReflectDefault` type
```rust
#[derive(Clone)]
pub struct ReflectDefault {
default: fn() -> Box<dyn Reflect>,
}
impl ReflectDefault {
pub fn default(&self) -> Box<dyn Reflect> {
(self.default)()
}
}
impl<T: Reflect + Default> FromType<T> for ReflectDefault {
fn from_type() -> Self {
ReflectDefault {
default: || Box::new(T::default()),
}
}
}
```
2. add `#[reflect(Default)]` to all component types that implement `Default` and are user facing (so not `ComputedSize`, `CubemapVisibleEntities` etc.)
This makes it possible to add the default value of a component to an entity without any compile-time information:
```rust
fn main() {
let mut app = App::new();
app.register_type::<Camera>();
let type_registry = app.world.get_resource::<TypeRegistry>().unwrap();
let type_registry = type_registry.read();
let camera_registration = type_registry.get(std::any::TypeId::of::<Camera>()).unwrap();
let reflect_default = camera_registration.data::<ReflectDefault>().unwrap();
let reflect_component = camera_registration
.data::<ReflectComponent>()
.unwrap()
.clone();
let default = reflect_default.default();
drop(type_registry);
let entity = app.world.spawn().id();
reflect_component.add_component(&mut app.world, entity, &*default);
let camera = app.world.entity(entity).get::<Camera>().unwrap();
dbg!(&camera);
}
```
### Open questions
- should we have `ReflectDefault` or `ReflectFromWorld` or both?
Supercedes https://github.com/bevyengine/bevy/pull/3340, and absorbs the test from there.
# Objective
- Fixes#3329
## Solution
- If the `Children` component has changed, we currently do not have a way to know how it has changed.
- Therefore, we must update the hierarchy downwards from that point to be correct.

# Objective
- While animating 501 https://github.com/KhronosGroup/glTF-Sample-Models/tree/master/2.0/BrainStem, I noticed things were getting a little slow
- Looking in tracy, the system `extract_skinned_meshes` is taking a lot of time, with a mean duration of 15.17ms
## Solution

- Compute the affine matrix as an `Affine3A` instead
- Remove the `temp` vec

# Objective
- Improve transform propagation performance
## Solution
- Use `Changed<Transform>` as part of the `root_query` and `transform_query` to avoid the indirection of having to look up the `Entity` in the `changed_transform_query`
- Get rid of the `changed_transform_query` entirely
- `transform_propagate_system` execution time for `many_cubes -- sphere` dropped from 1.07ms to 0.159ms, an 85% reduction for this system. Frame rate increased from ~42fps to ~44fps
# Objective
- Hierarchy tools are not just used for `Transform`: they are also used for scenes.
- In the future there's interest in using them for other features, such as visiibility inheritance.
- The fact that these tools are found in `bevy_transform` causes a great deal of user and developer confusion
- Fixes#2758.
## Solution
- Split `bevy_transform` into two!
- Make everything work again.
Note that this is a very tightly scoped PR: I *know* there are code quality and docs issues that existed in bevy_transform that I've just moved around. We should fix those in a seperate PR and try to merge this ASAP to reduce the bitrot involved in splitting an entire crate.
## Frustrations
The API around `GlobalTransform` is a mess: we have massive code and docs duplication, no link between the two types and no clear way to extend this to other forms of inheritance.
In the medium-term, I feel pretty strongly that `GlobalTransform` should be replaced by something like `Inherited<Transform>`, which lives in `bevy_hierarchy`:
- avoids code duplication
- makes the inheritance pattern extensible
- links the types at the type-level
- allows us to remove all references to inheritance from `bevy_transform`, making it more useful as a standalone crate and cleaning up its docs

# Objective
Lets say we need to rotate stretched object for this purpose we can created stretched `Child` and add as child to `Parent`, later we can rotate `Parent`, `Child` in this situation should rotate keeping it form, it is not the case with `SpriteBundle` currently. If you try to do it with `SpriteBundle` it will deform.
## Solution
My pull request fixes order of transformations to scale -> rotate -> translate, with this fix `SpriteBundle` behaves as expected in described rotation, without deformation. Here is quote from "Essential Mathematics for Games":
> Generally, the desired order we wish to use for these transforms is to scale first, then rotate, then translate. Scaling first gives us the scaling along the axes we expect. We can then rotate around the origin of the frame, and then translate it into place.
I'm must say when I was using `MaterialMesh2dBundle` it behaves correctly in both cases with `bevy main` and with my fix, don't know why, was not able to figure it out why there is difference.
here is code I was using for testing:
```rust
use bevy::{
prelude::*,
render::render_resource::{Extent3d, TextureDimension, TextureFormat},
sprite::{MaterialMesh2dBundle, Mesh2dHandle},
};
fn main() {
let mut app = App::new();
app.insert_resource(ClearColor(Color::rgb(0.1, 0.2, 0.3)))
.add_plugins(DefaultPlugins)
.add_startup_system(setup);
app.run();
}
fn setup(
mut commands: Commands,
mut images: ResMut<Assets<Image>>,
mut meshes: ResMut<Assets<Mesh>>,
mut materials: ResMut<Assets<ColorMaterial>>,
) {
let mut c = OrthographicCameraBundle::new_2d();
c.orthographic_projection.scale = 1.0 / 10.0;
commands.spawn_bundle(c);
// note: mesh somehow works for both variants
// let quad: Mesh2dHandle = meshes.add(Mesh::from(shape::Quad::default())).into();
// let child = commands
// .spawn_bundle(MaterialMesh2dBundle {
// mesh: quad.clone(),
// transform: Transform::from_translation(Vec3::new(0.0, 0.0, -1.0))
// .with_scale(Vec3::new(10.0, 1.0, 1.0)),
// material: materials.add(ColorMaterial::from(Color::BLACK)),
// ..Default::default()
// })
// .id();
// commands
// .spawn_bundle(MaterialMesh2dBundle {
// mesh: quad,
// transform: Transform::from_rotation(Quat::from_rotation_z(0.78))
// .with_translation(Vec3::new(0.0, 0.0, 10.0)),
// material: materials.add(ColorMaterial::from(Color::WHITE)),
// ..Default::default()
// })
// .push_children(&[child]);
let white = images.add(get_image(Color::rgb(1.0, 1.0, 1.0)));
let black = images.add(get_image(Color::rgb(0.0, 0.0, 0.0)));
let child = commands
.spawn_bundle(SpriteBundle {
texture: black,
transform: Transform::from_translation(Vec3::new(0.0, 0.0, -1.0))
.with_scale(Vec3::new(10.0, 1.0, 1.0)),
..Default::default()
})
.id();
commands
.spawn_bundle(SpriteBundle {
texture: white,
transform: Transform::from_rotation(Quat::from_rotation_z(0.78))
.with_translation(Vec3::new(0.0, 0.0, 10.0)),
..Default::default()
})
.push_children(&[child]);
}
fn get_image(color: Color) -> Image {
let mut bytes = Vec::with_capacity((1 * 1 * 4 * 4) as usize);
let color = color.as_rgba_f32();
bytes.extend(color[0].to_le_bytes());
bytes.extend(color[1].to_le_bytes());
bytes.extend(color[2].to_le_bytes());
bytes.extend(1.0_f32.to_le_bytes());
Image::new(
Extent3d {
width: 1,
height: 1,
depth_or_array_layers: 1,
},
TextureDimension::D2,
bytes,
TextureFormat::Rgba32Float,
)
}
```
here is screenshot with `bevy main` and my fix:
What is says on the tin.
This has got more to do with making `clippy` slightly more *quiet* than it does with changing anything that might greatly impact readability or performance.
that said, deriving `Default` for a couple of structs is a nice easy win
# Objective
- Bevy currently has no simple way to make an "empty" Entity work correctly in a Hierachy.
- The current Solution is to insert a Tuple instead:
```rs
.insert_bundle((Transform::default(), GlobalTransform::default()))
```
## Solution
* Add a `TransformBundle` that combines the Components:
```rs
.insert_bundle(TransformBundle::default())
```
* The code is based on #2331, except for missing the more controversial usage of `TransformBundle` as a Sub-bundle in preexisting Bundles.

# Objective
- Missing obvious way to rotate a transform around a point. This is popularly used for rotation of an object in world space ("orbiting" a point), or for local rotation of an object around a pivot point on that object.
- Present in other (not to be named) game engines
- Was question from user on Discord today (thread "object rotation")
## Solution
- Added Transform::rotate_around method where point is specified in reference frame of the parent (if any) or in world space.
# Objective
bevy_transform needed documentation and warn(missing_docs) as requested by #3492
## Solution
warn(missing_docs) was activated and documentation was added to cover the crate

# Objective
CI should check for missing backticks in doc comments.
Fixes#3435
## Solution
`clippy` has a lint for this: `doc_markdown`. This enables that lint in the CI script.
Of course, enabling this lint in CI causes a bunch of lint errors, so I've gone through and fixed all of them. This was a huge edit that touched a ton of files, so I split the PR up by crate.
When all of the following are merged, the CI should pass and this can be merged.

#3457 adds the `doc_markdown` clippy lint, which checks doc comments to make sure code identifiers are escaped with backticks. This causes a lot of lint errors, so this is one of a number of PR's that will fix those lint errors one crate at a time.
This PR fixes lints in the `bevy_transform` crate.
# Objective
Fix#2406
Scene parenting was not done completely, leaving the hierarchy maintenance to the standard system. As scene spawning happens in stage `PreUpdate` and hierarchy maintenance in stage `PostUpdate`, this left the scene in an invalid state parent wise for part of a frame
## Solution
Also add/update the `Children` component when spawning the scene.
I kept the `Children` component as a `SmallVec`, it could be moved to an `HashSet` to guarantee uniqueness

This implements the most minimal variant of #1843 - a derive for marker trait. This is a prerequisite to more complicated features like statically defined storage type or opt-out component reflection.
In order to make component struct's purpose explicit and avoid misuse, it must be annotated with `#[derive(Component)]` (manual impl is discouraged for compatibility). Right now this is just a marker trait, but in the future it might be expanded. Making this change early allows us to make further changes later without breaking backward compatibility for derive macro users.
This already prevents a lot of issues, like using bundles in `insert` calls. Primitive types are no longer valid components as well. This can be easily worked around by adding newtype wrappers and deriving `Component` for them.
One funny example of prevented bad code (from our own tests) is when an newtype struct or enum variant is used. Previously, it was possible to write `insert(Newtype)` instead of `insert(Newtype(value))`. That code compiled, because function pointers (in this case newtype struct constructor) implement `Send + Sync + 'static`, so we allowed them to be used as components. This is no longer the case and such invalid code will trigger a compile error.

# Objective
Noticed a comment saying changed detection should be enabled for hierarchy maintenance once stable
Fixes#891
## Solution
Added `Changed<Parent>` filter on the query
# Objective
Make it easier to construct transforms. E.g.
```rs
Transform::from_xyz(0.0, 0.0, 10.0).with_scale(Vec3::splat(2.0))
```
I found myself writing an extension method to do this so I don't have to write:
```rs
Transform {
translation: Vec3::new(0.0, 0.0, 10.0),
scale: Vec3::splat(2.0),
..Default::default()
}
```
## Solution
Add *builder style* methods to `Transform`.
Methods:
- `with_translation`
- `with_rotation`
- `with_scale`
I also added these methods to `GlobalTransform`. But they are probably less useful there.
# Objective
Enable using exact World lifetimes during read-only access . This is motivated by the new renderer's need to allow read-only world-only queries to outlive the query itself (but still be constrained by the world lifetime).
For example:
115b170d1f/pipelined/bevy_pbr2/src/render/mod.rs (L774)
## Solution
Split out SystemParam state and world lifetimes and pipe those lifetimes up to read-only Query ops (and add into_inner for Res). According to every safety test I've run so far (except one), this is safe (see the temporary safety test commit). Note that changing the mutable variants to the new lifetimes would allow aliased mutable pointers (try doing that to see how it affects the temporary safety tests).
The new state lifetime on SystemParam does make `#[derive(SystemParam)]` more cumbersome (the current impl requires PhantomData if you don't use both lifetimes). We can make this better by detecting whether or not a lifetime is used in the derive and adjusting accordingly, but that should probably be done in its own pr.
## Why is this a draft?
The new lifetimes break QuerySet safety in one very specific case (see the query_set system in system_safety_test). We need to solve this before we can use the lifetimes given.
This is due to the fact that QuerySet is just a wrapper over Query, which now relies on world lifetimes instead of `&self` lifetimes to prevent aliasing (but in systems, each Query has its own implied lifetime, not a centralized world lifetime). I believe the fix is to rewrite QuerySet to have its own World lifetime (and own the internal reference). This will complicate the impl a bit, but I think it is doable. I'm curious if anyone else has better ideas.
Personally, I think these new lifetimes need to happen. We've gotta have a way to directly tie read-only World queries to the World lifetime. The new renderer is the first place this has come up, but I doubt it will be the last. Worst case scenario we can come up with a second `WorldLifetimeQuery<Q, F = ()>` parameter to enable these read-only scenarios, but I'd rather not add another type to the type zoo.
## Objective
- Clean up remaining references to the trait `FromResources`, which was replaced in favor of `FromWorld` during the ECS rework.
## Solution
- Remove the derive macro for `FromResources`
- Change doc references of `FromResources` to `FromWorld`
(this is the first item in #2576)
## Objective
This code would result in a crash:
```rust
use bevy::prelude::*;
fn main() {
let mut world = World::new();
let child = world.spawn().id();
world.spawn().push_children(&[child]);
}
```
## Solution
Update the `EntityMut`'s location after inserting a component on the children entities, as it may have changed.
# Objective
- Remove all the `.system()` possible.
- Check for remaining missing cases.
## Solution
- Remove all `.system()`, fix compile errors
- 32 calls to `.system()` remains, mostly internals, the few others should be removed after #2446
This is extracted out of eb8f973646476b4a4926ba644a77e2b3a5772159 and includes some additional changes to remove all references to AppBuilder and fix examples that still used App::build() instead of App::new(). In addition I didn't extract the sub app feature as it isn't ready yet.
You can use `git diff --diff-filter=M eb8f973646476b4a4926ba644a77e2b3a5772159` to find all differences in this PR. The `--diff-filtered=M` filters all files added in the original commit but not in this commit away.

# Objective
- Currently `Commands` are quite slow due to the need to allocate for each command and wrap it in a `Box<dyn Command>`.
- For example:
```rust
fn my_system(mut cmds: Commands) {
cmds.spawn().insert(42).insert(3.14);
}
```
will have 3 separate `Box<dyn Command>` that need to be allocated and ran.
## Solution
- Utilize a specialized data structure keyed `CommandQueueInner`.
- The purpose of `CommandQueueInner` is to hold a collection of commands in contiguous memory.
- This allows us to store each `Command` type contiguously in memory and quickly iterate through them and apply the `Command::write` trait function to each element.
# Objective
- CI jobs are starting to fail due to `clippy::bool-assert-comparison` and `clippy::single_component_path_imports` being triggered.
## Solution
- Fix all uses where `asset_eq!(<condition>, <bool>)` could be replace by `assert!`
- Move the `#[allow()]` for `single_component_path_imports` to `#![allow()]` at the start of the files.
Continuing the work on reducing the safety footguns in the code, I've removed one extra `UnsafeCell` in favour of safe `Cell` usage inisde `ComponentTicks`. That change led to discovery of misbehaving component insert logic, where data wasn't properly dropped when overwritten. Apart from that being fixed, some method names were changed to better convey the "initialize new allocation" and "replace existing allocation" semantic.
Depends on #2221, I will rebase this PR after the dependency is merged. For now, review just the last commit.

Fixes#2274
When calling `despawn_recursive`, the recursive loop doesn't need to remove the entity from the children list of its parent when the parent will also be deleted
Upside:
* Removes two entity lookup per entity being recursively despawned
Downside:
* The change detection on the `Children` component of a deleted entity in the despawned hierarchy will not be triggered
The only API to add a parent/child relationship between existing entities is through commands, there is no easy way to do it from `World`. Manually inserting the components is not completely possible since `PreviousParent` has no public constructor.
This PR adds two methods to set entities as children of an `EntityMut`: `insert_children` and `push_children`. ~~The API is similar to the one on `Commands`, except that the parent is the `EntityMut`.~~ The API is the same as in #1703.
However, the `Parent` and `Children` components are defined in `bevy_transform` which depends on `bevy_ecs`, while `EntityMut` is defined in `bevy_ecs`, so the methods are added to the `BuildWorldChildren` trait instead.
If #1545 is merged this should be fixed too.
I'm aware cart was experimenting with entity hierarchies, but unless it's a coming soon this PR would be useful to have meanwhile.

Resolves#1253#1562
This makes the Commands apis consistent with World apis. This moves to a "type state" pattern (like World) where the "current entity" is stored in an `EntityCommands` builder.
In general this tends to cuts down on indentation and line count. It comes at the cost of needing to type `commands` more and adding more semicolons to terminate expressions.
I also added `spawn_bundle` to Commands because this is a common enough operation that I think its worth providing a shorthand.
fixes#1599
* Added doc on `Transform` and `GlobalTransform` to describe usage and how `GlobalTransform` is updated
* Documented all methods on `Transform`
* `#[doc(hidden)]` most constructors and methods mutating `GlobalTransform`, documented the other
* Mentioned z-ordering for `Transform` in 2d
it's a followup of #1550
I think calling explicit methods/values instead of default makes the code easier to read: "what is `Quat::default()`" vs "Oh, it's `Quat::IDENTITY`"
`Transform::identity()` and `GlobalTransform::identity()` can also be consts and I replaced the calls to their `default()` impl with `identity()`
This is an effort to provide the correct `#[reflect_value(...)]` attributes where they are needed.
Supersedes #1533 and resolves#1528.
---
I am working under the following assumptions (thanks to @bjorn3 and @Davier for advice here):
- Any `enum` that derives `Reflect` and one or more of { `Serialize`, `Deserialize`, `PartialEq`, `Hash` } needs a `#[reflect_value(...)]` attribute containing the same subset of { `Serialize`, `Deserialize`, `PartialEq`, `Hash` } that is present on the derive.
- Same as above for `struct` and `#[reflect(...)]`, respectively.
- If a `struct` is used as a component, it should also have `#[reflect(Component)]`
- All reflected types should be registered in their plugins
I treated the following as components (added `#[reflect(Component)]` if necessary):
- `bevy_render`
- `struct RenderLayers`
- `bevy_transform`
- `struct GlobalTransform`
- `struct Parent`
- `struct Transform`
- `bevy_ui`
- `struct Style`
Not treated as components:
- `bevy_math`
- `struct Size<T>`
- `struct Rect<T>`
- Note: The updates for `Size<T>` and `Rect<T>` in `bevy::math::geometry` required using @Davier's suggestion to add `+ PartialEq` to the trait bound. I then registered the specific types used over in `bevy_ui` such as `Size<Val>`, etc. in `bevy_ui`'s plugin, since `bevy::math` does not contain a plugin.
- `bevy_render`
- `struct Color`
- `struct PipelineSpecialization`
- `struct ShaderSpecialization`
- `enum PrimitiveTopology`
- `enum IndexFormat`
Not Addressed:
- I am not searching for components in Bevy that are _not_ reflected. So if there are components that are not reflected that should be reflected, that will need to be figured out in another PR.
- I only added `#[reflect(...)]` or `#[reflect_value(...)]` entries for the set of four traits { `Serialize`, `Deserialize`, `PartialEq`, `Hash` } _if they were derived via `#[derive(...)]`_. I did not look for manual trait implementations of the same set of four, nor did I consider any traits outside the four. Are those other possibilities something that needs to be looked into?
