Add Support for Triggering Events via AnimationEvents (#15538)
# Objective Add support for events that can be triggered from animation clips. This is useful when you need something to happen at a specific time in an animation. For example, playing a sound every time a characters feet hits the ground when walking. Closes #15494 ## Solution Added a new field to `AnimationClip`: `events`, which contains a list of `AnimationEvent`s. These are automatically triggered in `animate_targets` and `trigger_untargeted_animation_events`. ## Testing Added a couple of tests and example (`animation_events.rs`) to make sure events are triggered when expected. --- ## Showcase `Events` need to also implement `AnimationEvent` and `Reflect` to be used with animations. ```rust #[derive(Event, AnimationEvent, Reflect)] struct SomeEvent; ``` Events can be added to an `AnimationClip` by specifying a time and event. ```rust // trigger an event after 1.0 second animation_clip.add_event(1.0, SomeEvent); ``` And optionally, providing a target id. ```rust let id = AnimationTargetId::from_iter(["shoulder", "arm", "hand"]); animation_clip.add_event_to_target(id, 1.0, HandEvent); ``` I modified the `animated_fox` example to show off the feature.  --------- Co-authored-by: Matty <weatherleymatthew@gmail.com> Co-authored-by: Chris Biscardi <chris@christopherbiscardi.com> Co-authored-by: François Mockers <francois.mockers@vleue.com> |

Migrate cameras to required components (#15641)
# Objective Yet another PR for migrating stuff to required components. This time, cameras! ## Solution As per the [selected proposal](https://hackmd.io/tsYID4CGRiWxzsgawzxG_g#Combined-Proposal-1-Selected), deprecate `Camera2dBundle` and `Camera3dBundle` in favor of `Camera2d` and `Camera3d`. Adding a `Camera` without `Camera2d` or `Camera3d` now logs a warning, as suggested by Cart [on Discord](https://discord.com/channels/691052431525675048/1264881140007702558/1291506402832945273). I would personally like cameras to work a bit differently and be split into a few more components, to avoid some footguns and confusing semantics, but that is more controversial, and shouldn't block this core migration. ## Testing I ran a few 2D and 3D examples, and tried cameras with and without render graphs. --- ## Migration Guide `Camera2dBundle` and `Camera3dBundle` have been deprecated in favor of `Camera2d` and `Camera3d`. Inserting them will now also insert the other components required by them automatically. |

Implement additive blending for animation graphs. (#15631)
*Additive blending* is an ubiquitous feature in game engines that allows animations to be concatenated instead of blended. The canonical use case is to allow a character to hold a weapon while performing arbitrary poses. For example, if you had a character that needed to be able to walk or run while attacking with a weapon, the typical workflow is to have an additive blend node that combines walking and running animation clips with an animation clip of one of the limbs performing a weapon attack animation. This commit adds support for additive blending to Bevy. It builds on top of the flexible infrastructure in #15589 and introduces a new type of node, the *add node*. Like blend nodes, add nodes combine the animations of their children according to their weights. Unlike blend nodes, however, add nodes don't normalize the weights to 1.0. The `animation_masks` example has been overhauled to demonstrate the use of additive blending in combination with masks. There are now controls to choose an animation clip for every limb of the fox individually. This patch also fixes a bug whereby masks were incorrectly accumulated with `insert()` during the graph threading phase, which could cause corruption of computed masks in some cases. Note that the `clip` field has been replaced with an `AnimationNodeType` enum, which breaks `animgraph.ron` files. The `Fox.animgraph.ron` asset has been updated to the new format. Closes #14395. ## Showcase https://github.com/user-attachments/assets/52dfe05f-fdb3-477a-9462-ec150f93df33 ## Migration Guide * The `animgraph.ron` format has changed to accommodate the new *additive blending* feature. You'll need to change `clip` fields to instances of the new `AnimationNodeType` enum. |

Impose a more sensible ordering for animation graph evaluation. (#15589)
This is an updated version of #15530. Review comments were addressed. This commit changes the animation graph evaluation to be operate in a more sensible order and updates the semantics of blend nodes to conform to [the animation composition RFC]. Prior to this patch, a node graph like this: ``` ┌─────┐ │ │ │ 1 │ │ │ └──┬──┘ │ ┌───────┴───────┐ │ │ ▼ ▼ ┌─────┐ ┌─────┐ │ │ │ │ │ 2 │ │ 3 │ │ │ │ │ └──┬──┘ └──┬──┘ │ │ ┌───┴───┐ ┌───┴───┐ │ │ │ │ ▼ ▼ ▼ ▼ ┌─────┐ ┌─────┐ ┌─────┐ ┌─────┐ │ │ │ │ │ │ │ │ │ 4 │ │ 6 │ │ 5 │ │ 7 │ │ │ │ │ │ │ │ │ └─────┘ └─────┘ └─────┘ └─────┘ ``` Would be evaluated as (((4 ⊕ 5) ⊕ 6) ⊕ 7), with the blend (lerp/slerp) operation notated as ⊕. As quaternion multiplication isn't commutative, this is very counterintuitive and will especially lead to trouble with the forthcoming additive blending feature (#15198). This patch fixes the issue by changing the evaluation order to postorder, with children of a node evaluated in ascending order by node index. To do so, this patch revamps `AnimationCurve` to be based on an *evaluation stack* and a *blend register*. During target evaluation, the graph evaluator traverses the graph in postorder. When encountering a clip node, the evaluator pushes the possibly-interpolated value onto the evaluation stack. When encountering a blend node, the evaluator pops values off the stack into the blend register, accumulating weights as appropriate. When the graph is completely evaluated, the top element on the stack is *committed* to the property of the component. A new system, the *graph threading* system, is added in order to cache the sorted postorder traversal to avoid the overhead of sorting children at animation evaluation time. Mask evaluation has been moved to this system so that the graph only has to be traversed at most once per frame. Unlike the `ActiveAnimation` list, the *threaded graph* is cached from frame to frame and only has to be regenerated when the animation graph asset changes. This patch currently regresses the `animate_target` performance in `many_foxes` by around 50%, resulting in an FPS loss of about 2-3 FPS. I'd argue that this is an acceptable price to pay for a much more intuitive system. In the future, we can mitigate the regression with a fast path that avoids consulting the graph if only one animation is playing. However, in the interest of keeping this patch simple, I didn't do so here.

Migrate scenes to required components (#15579)
# Objective A step in the migration to required components: scenes! ## Solution As per the [selected proposal](https://hackmd.io/@bevy/required_components/%2FPJtNGVMMQhyM0zIvCJSkbA): - Deprecate `SceneBundle` and `DynamicSceneBundle`. - Add `SceneRoot` and `DynamicSceneRoot` components, which wrap a `Handle<Scene>` and `Handle<DynamicScene>` respectively. ## Migration Guide Asset handles for scenes and dynamic scenes must now be wrapped in the `SceneRoot` and `DynamicSceneRoot` components. Raw handles as components no longer spawn scenes. Additionally, `SceneBundle` and `DynamicSceneBundle` have been deprecated. Instead, use the scene components directly. Previously: ```rust let model_scene = asset_server.load(GltfAssetLabel::Scene(0).from_asset("model.gltf")); commands.spawn(SceneBundle { scene: model_scene, transform: Transform::from_xyz(-4.0, 0.0, -3.0), ..default() }); ``` Now: ```rust let model_scene = asset_server.load(GltfAssetLabel::Scene(0).from_asset("model.gltf")); commands.spawn(( SceneRoot(model_scene), Transform::from_xyz(-4.0, 0.0, -3.0), )); ``` |

Migrate meshes and materials to required components (#15524)
# Objective A big step in the migration to required components: meshes and materials! ## Solution As per the [selected proposal](https://hackmd.io/@bevy/required_components/%2Fj9-PnF-2QKK0on1KQ29UWQ): - Deprecate `MaterialMesh2dBundle`, `MaterialMeshBundle`, and `PbrBundle`. - Add `Mesh2d` and `Mesh3d` components, which wrap a `Handle<Mesh>`. - Add `MeshMaterial2d<M: Material2d>` and `MeshMaterial3d<M: Material>`, which wrap a `Handle<M>`. - Meshes *without* a mesh material should be rendered with a default material. The existence of a material is determined by `HasMaterial2d`/`HasMaterial3d`, which is required by `MeshMaterial2d`/`MeshMaterial3d`. This gets around problems with the generics. Previously: ```rust commands.spawn(MaterialMesh2dBundle { mesh: meshes.add(Circle::new(100.0)).into(), material: materials.add(Color::srgb(7.5, 0.0, 7.5)), transform: Transform::from_translation(Vec3::new(-200., 0., 0.)), ..default() }); ``` Now: ```rust commands.spawn(( Mesh2d(meshes.add(Circle::new(100.0))), MeshMaterial2d(materials.add(Color::srgb(7.5, 0.0, 7.5))), Transform::from_translation(Vec3::new(-200., 0., 0.)), )); ``` If the mesh material is missing, previously nothing was rendered. Now, it renders a white default `ColorMaterial` in 2D and a `StandardMaterial` in 3D (this can be overridden). Below, only every other entity has a material:   Why white? This is still open for discussion, but I think white makes sense for a *default* material, while *invalid* asset handles pointing to nothing should have something like a pink material to indicate that something is broken (I don't handle that in this PR yet). This is kind of a mix of Godot and Unity: Godot just renders a white material for non-existent materials, while Unity renders nothing when no materials exist, but renders pink for invalid materials. I can also change the default material to pink if that is preferable though. ## Testing I ran some 2D and 3D examples to test if anything changed visually. I have not tested all examples or features yet however. If anyone wants to test more extensively, it would be appreciated! ## Implementation Notes - The relationship between `bevy_render` and `bevy_pbr` is weird here. `bevy_render` needs `Mesh3d` for its own systems, but `bevy_pbr` has all of the material logic, and `bevy_render` doesn't depend on it. I feel like the two crates should be refactored in some way, but I think that's out of scope for this PR. - I didn't migrate meshlets to required components yet. That can probably be done in a follow-up, as this is already a huge PR. - It is becoming increasingly clear to me that we really, *really* want to disallow raw asset handles as components. They caused me a *ton* of headache here already, and it took me a long time to find every place that queried for them or inserted them directly on entities, since there were no compiler errors for it. If we don't remove the `Component` derive, I expect raw asset handles to be a *huge* footgun for users as we transition to wrapper components, especially as handles as components have been the norm so far. I personally consider this to be a blocker for 0.15: we need to migrate to wrapper components for asset handles everywhere, and remove the `Component` derive. Also see https://github.com/bevyengine/bevy/issues/14124. --- ## Migration Guide Asset handles for meshes and mesh materials must now be wrapped in the `Mesh2d` and `MeshMaterial2d` or `Mesh3d` and `MeshMaterial3d` components for 2D and 3D respectively. Raw handles as components no longer render meshes. Additionally, `MaterialMesh2dBundle`, `MaterialMeshBundle`, and `PbrBundle` have been deprecated. Instead, use the mesh and material components directly. Previously: ```rust commands.spawn(MaterialMesh2dBundle { mesh: meshes.add(Circle::new(100.0)).into(), material: materials.add(Color::srgb(7.5, 0.0, 7.5)), transform: Transform::from_translation(Vec3::new(-200., 0., 0.)), ..default() }); ``` Now: ```rust commands.spawn(( Mesh2d(meshes.add(Circle::new(100.0))), MeshMaterial2d(materials.add(Color::srgb(7.5, 0.0, 7.5))), Transform::from_translation(Vec3::new(-200., 0., 0.)), )); ``` If the mesh material is missing, a white default material is now used. Previously, nothing was rendered if the material was missing. The `WithMesh2d` and `WithMesh3d` query filter type aliases have also been removed. Simply use `With<Mesh2d>` or `With<Mesh3d>`. --------- Co-authored-by: Tim Blackbird <justthecooldude@gmail.com> Co-authored-by: Carter Anderson <mcanders1@gmail.com> |

Migrate lights to required components (#15554)

Curve-based animation (#15434)
# Objective This PR extends and reworks the material from #15282 by allowing arbitrary curves to be used by the animation system to animate arbitrary properties. The goals of this work are to: - Allow far greater flexibility in how animations are allowed to be defined in order to be used with `bevy_animation`. - Delegate responsibility over keyframe interpolation to `bevy_math` and the `Curve` libraries and reduce reliance on keyframes in animation definitions generally. - Move away from allowing the glTF spec to completely define animations on a mechanical level. ## Solution ### Overview At a high level, curves have been incorporated into the animation system using the `AnimationCurve` trait (closely related to what was `Keyframes`). From the top down: 1. In `animate_targets`, animations are driven by `VariableCurve`, which is now a thin wrapper around a `Box<dyn AnimationCurve>`. 2. `AnimationCurve` is something built out of a `Curve`, and it tells the animation system how to use the curve's output to actually mutate component properties. The trait looks like this: ```rust /// A low-level trait that provides control over how curves are actually applied to entities /// by the animation system. /// /// Typically, this will not need to be implemented manually, since it is automatically /// implemented by [`AnimatableCurve`] and other curves used by the animation system /// (e.g. those that animate parts of transforms or morph weights). However, this can be /// implemented manually when `AnimatableCurve` is not sufficiently expressive. /// /// In many respects, this behaves like a type-erased form of [`Curve`], where the output /// type of the curve is remembered only in the components that are mutated in the /// implementation of [`apply`]. /// /// [`apply`]: AnimationCurve::apply pub trait AnimationCurve: Reflect + Debug + Send + Sync { /// Returns a boxed clone of this value. fn clone_value(&self) -> Box<dyn AnimationCurve>; /// The range of times for which this animation is defined. fn domain(&self) -> Interval; /// Write the value of sampling this curve at time `t` into `transform` or `entity`, /// as appropriate, interpolating between the existing value and the sampled value /// using the given `weight`. fn apply<'a>( &self, t: f32, transform: Option<Mut<'a, Transform>>, entity: EntityMutExcept<'a, (Transform, AnimationPlayer, Handle<AnimationGraph>)>, weight: f32, ) -> Result<(), AnimationEvaluationError>; } ``` 3. The conversion process from a `Curve` to an `AnimationCurve` involves using wrappers which communicate the intent to animate a particular property. For example, here is `TranslationCurve`, which wraps a `Curve<Vec3>` and uses it to animate `Transform::translation`: ```rust /// This type allows a curve valued in `Vec3` to become an [`AnimationCurve`] that animates /// the translation component of a transform. pub struct TranslationCurve<C>(pub C); ``` ### Animatable Properties The `AnimatableProperty` trait survives in the transition, and it can be used to allow curves to animate arbitrary component properties. The updated documentation for `AnimatableProperty` explains this process: <details> <summary>Expand AnimatableProperty example</summary An `AnimatableProperty` is a value on a component that Bevy can animate. You can implement this trait on a unit struct in order to support animating custom components other than transforms and morph weights. Use that type in conjunction with `AnimatableCurve` (and perhaps `AnimatableKeyframeCurve` to define the animation itself). For example, in order to animate font size of a text section from 24 pt. to 80 pt., you might use: ```rust #[derive(Reflect)] struct FontSizeProperty; impl AnimatableProperty for FontSizeProperty { type Component = Text; type Property = f32; fn get_mut(component: &mut Self::Component) -> Option<&mut Self::Property> { Some(&mut component.sections.get_mut(0)?.style.font_size) } } ``` You can then create an `AnimationClip` to animate this property like so: ```rust let mut animation_clip = AnimationClip::default(); animation_clip.add_curve_to_target( animation_target_id, AnimatableKeyframeCurve::new( [ (0.0, 24.0), (1.0, 80.0), ] ) .map(AnimatableCurve::<FontSizeProperty, _>::from_curve) .expect("Failed to create font size curve") ); ``` Here, the use of `AnimatableKeyframeCurve` creates a curve out of the given keyframe time-value pairs, using the `Animatable` implementation of `f32` to interpolate between them. The invocation of `AnimatableCurve::from_curve` with `FontSizeProperty` indicates that the `f32` output from that curve is to be used to animate the font size of a `Text` component (as configured above). </details> ### glTF Loading glTF animations are now loaded into `Curve` types of various kinds, depending on what is being animated and what interpolation mode is being used. Those types get wrapped into and converted into `Box<dyn AnimationCurve>` and shoved inside of a `VariableCurve` just like everybody else. ### Morph Weights There is an `IterableCurve` abstraction which allows sampling these from a contiguous buffer without allocating. Its only reason for existing is that Rust disallows you from naming function types, otherwise we would just use `Curve` with an iterator output type. (The iterator involves `Map`, and the name of the function type would have to be able to be named, but it is not.) A `WeightsCurve` adaptor turns an `IterableCurve` into an `AnimationCurve`, so it behaves like everything else in that regard. ## Testing Tested by running existing animation examples. Interpolation logic has had additional tests added within the `Curve` API to replace the tests in `bevy_animation`. Some kinds of out-of-bounds errors have become impossible. Performance testing on `many_foxes` (`animate_targets`) suggests that performance is very similar to the existing implementation. Here are a couple trace histograms across different runs (yellow is this branch, red is main). <img width="669" alt="Screenshot 2024-09-27 at 9 41 50 AM" src="https://github.com/user-attachments/assets/5ba4e9ac-3aea-452e-aaf8-1492acc2d7fc"> <img width="673" alt="Screenshot 2024-09-27 at 9 45 18 AM" src="https://github.com/user-attachments/assets/8982538b-04cf-46b5-97b2-164c6bc8162e"> --- ## Migration Guide Most user code that does not directly deal with `AnimationClip` and `VariableCurve` will not need to be changed. On the other hand, `VariableCurve` has been completely overhauled. If you were previously defining animation curves in code using keyframes, you will need to migrate that code to use curve constructors instead. For example, a rotation animation defined using keyframes and added to an animation clip like this: ```rust animation_clip.add_curve_to_target( animation_target_id, VariableCurve { keyframe_timestamps: vec![0.0, 1.0, 2.0, 3.0, 4.0], keyframes: Keyframes::Rotation(vec![ Quat::IDENTITY, Quat::from_axis_angle(Vec3::Y, PI / 2.), Quat::from_axis_angle(Vec3::Y, PI / 2. * 2.), Quat::from_axis_angle(Vec3::Y, PI / 2. * 3.), Quat::IDENTITY, ]), interpolation: Interpolation::Linear, }, ); ``` would now be added like this: ```rust animation_clip.add_curve_to_target( animation_target_id, AnimatableKeyframeCurve::new([0.0, 1.0, 2.0, 3.0, 4.0].into_iter().zip([ Quat::IDENTITY, Quat::from_axis_angle(Vec3::Y, PI / 2.), Quat::from_axis_angle(Vec3::Y, PI / 2. * 2.), Quat::from_axis_angle(Vec3::Y, PI / 2. * 3.), Quat::IDENTITY, ])) .map(RotationCurve) .expect("Failed to build rotation curve"), ); ``` Note that the interface of `AnimationClip::add_curve_to_target` has also changed (as this example shows, if subtly), and now takes its curve input as an `impl AnimationCurve`. If you need to add a `VariableCurve` directly, a new method `add_variable_curve_to_target` accommodates that (and serves as a one-to-one migration in this regard). ### For reviewers The diff is pretty big, and the structure of some of the changes might not be super-obvious: - `keyframes.rs` became `animation_curves.rs`, and `AnimationCurve` is based heavily on `Keyframes`, with the adaptors also largely following suite. - The Curve API adaptor structs were moved from `bevy_math::curve::mod` into their own module `adaptors`. There are no functional changes to how these adaptors work; this is just to make room for the specialized reflection implementations since `mod.rs` was getting kind of cramped. - The new module `gltf_curves` holds the additional curve constructions that are needed by the glTF loader. Note that the loader uses a mix of these and off-the-shelf `bevy_math` curve stuff. - `animatable.rs` no longer holds logic related to keyframe interpolation, which is now delegated to the existing abstractions in `bevy_math::curve::cores`. --------- Co-authored-by: Gino Valente <49806985+MrGVSV@users.noreply.github.com> Co-authored-by: aecsocket <43144841+aecsocket@users.noreply.github.com> |

Add core and alloc over std Lints (#15281)
# 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. --------- Co-authored-by: François Mockers <francois.mockers@vleue.com> |

Allow animation clips to animate arbitrary properties. (#15282)
Currently, Bevy restricts animation clips to animating
`Transform::translation`, `Transform::rotation`, `Transform::scale`, or
`MorphWeights`, which correspond to the properties that glTF can
animate. This is insufficient for many use cases such as animating UI,
as the UI layout systems expect to have exclusive control over UI
elements' `Transform`s and therefore the `Style` properties must be
animated instead.
This commit fixes this, allowing for `AnimationClip`s to animate
arbitrary properties. The `Keyframes` structure has been turned into a
low-level trait that can be implemented to achieve arbitrary animation
behavior. Along with `Keyframes`, this patch adds a higher-level trait,
`AnimatableProperty`, that simplifies the task of animating single
interpolable properties. Built-in `Keyframes` implementations exist for
translation, rotation, scale, and morph weights. For the most part, you
can migrate by simply changing your code from
`Keyframes::Translation(...)` to `TranslationKeyframes(...)`, and
likewise for rotation, scale, and morph weights.
An example `AnimatableProperty` implementation for the font size of a
text section follows:
#[derive(Reflect)]
struct FontSizeProperty;
impl AnimatableProperty for FontSizeProperty {
type Component = Text;
type Property = f32;
fn get_mut(component: &mut Self::Component) -> Option<&mut
Self::Property> {
Some(&mut component.sections.get_mut(0)?.style.font_size)
}
}
In order to keep this patch relatively small, this patch doesn't include
an implementation of `AnimatableProperty` on top of the reflection
system. That can be a follow-up.
This patch builds on top of the new `EntityMutExcept<>` type in order to
widen the `AnimationTarget` query to include write access to all
components. Because `EntityMutExcept<>` has some performance overhead
over an explicit query, we continue to explicitly query `Transform` in
order to avoid regressing the performance of skeletal animation, such as
the `many_foxes` benchmark. I've measured the performance of that
benchmark and have found no significant regressions.
A new example, `animated_ui`, has been added. This example shows how to
use Bevy's built-in animation infrastructure to animate font size and
color, which wasn't possible before this patch.

`Box::new(RotationKeyframes(...))`, and
`Box::new(MorphWeightsKeyframes(...))` respectively.

Implement animation masks, allowing fine control of the targets that animations affect. (#15013)
This commit adds support for *masks* to the animation graph. A mask is a
set of animation targets (bones) that neither a node nor its descendants
are allowed to animate. Animation targets can be assigned one or more
*mask group*s, which are specific to a single graph. If a node masks out
any mask group that an animation target belongs to, animation curves for
that target will be ignored during evaluation.
The canonical use case for masks is to support characters holding
objects. Typically, character animations will contain hand animations in
the case that the character's hand is empty. (For example, running
animations may close a character's fingers into a fist.) However, when
the character is holding an object, the animation must be altered so
that the hand grips the object.
Bevy currently has no convenient way to handle this. The only workaround
that I can see is to have entirely separate animation clips for
characters' hands and bodies and keep them in sync, which is burdensome
and doesn't match artists' expectations from other engines, which all
effectively have support for masks. However, with mask group support,
this task is simple. We assign each hand to a mask group and parent all
character animations to a node. When a character grasps an object in
hand, we position the fingers as appropriate and then enable the mask
group for that hand in that node. This allows the character's animations
to run normally, while the object remains correctly attached to the
hand.
Note that even with this PR, we won't have support for running separate
animations for a character's hand and the rest of the character. This is
because we're missing additive blending: there's no way to combine the
two masked animations together properly. I intend that to be a follow-up
PR.
The major engines all have support for masks, though the workflow varies
from engine to engine:
* Unity has support for masks [essentially as implemented here], though
with layers instead of a tree. However, when using the Mecanim
("Humanoid") feature, precise control over bones is lost in favor of
predefined muscle groups.
* Unreal has a feature named [*layered blend per bone*]. This allows for
separate blend weights for different bones, effectively achieving masks.
I believe that the combination of blend nodes and masks make Bevy's
animation graph as expressible as that of Unreal, once we have support
for additive blending, though you may have to use more nodes than you
would in Unreal. Moreover, separating out the concepts of "blend weight"
and "which bones this node applies to" seems like a cleaner design than
what Unreal has.
* Godot's `AnimationTree` has the notion of [*blend filters*], which are
essentially the same as masks as implemented in this PR.
Additionally, this patch fixes a bug with weight evaluation whereby
weights weren't properly propagated down to grandchildren, because the
weight evaluation for a node only checked its parent's weight, not its
evaluated weight. I considered submitting this as a separate PR, but
given that this PR refactors that code entirely to support masks and
weights under a unified "evaluated node" concept, I simply included the
fix here.
A new example, `animation_masks`, has been added. It demonstrates how to
toggle masks on and off for specific portions of a skin.
This is part of #14395, but I'm going to defer closing that issue until
we have additive blending.
[essentially as implemented here]:

[*blend filters*]:
https://docs.godotengine.org/en/stable/tutorials/animation/animation_tree.html
## Migration Guide
* The serialized format of animation graphs has changed with the
addition of animation masks. To upgrade animation graph RON files, add
`mask` and `mask_groups` fields as appropriate. (They can be safely set
to zero.)

Have EntityCommands methods consume self for easier chaining (#14897)
# Objective Fixes #14883 ## Solution Pretty simple update to `EntityCommands` methods to consume `self` and return it rather than taking `&mut self`. The things probably worth noting: * I added `#[allow(clippy::should_implement_trait)]` to the `add` method because it causes a linting conflict with `std::ops::Add`. * `despawn` and `log_components` now return `Self`. I'm not sure if that's exactly the desired behavior so I'm happy to adjust if that seems wrong. ## Testing Tested with `cargo run -p ci`. I think that should be sufficient to call things good. ## Migration Guide The most likely migration needed is changing code from this: ``` let mut entity = commands.get_or_spawn(entity); if depth_prepass { entity.insert(DepthPrepass); } if normal_prepass { entity.insert(NormalPrepass); } if motion_vector_prepass { entity.insert(MotionVectorPrepass); } if deferred_prepass { entity.insert(DeferredPrepass); } ``` to this: ``` let mut entity = commands.get_or_spawn(entity); if depth_prepass { entity = entity.insert(DepthPrepass); } if normal_prepass { entity = entity.insert(NormalPrepass); } if motion_vector_prepass { entity = entity.insert(MotionVectorPrepass); } if deferred_prepass { entity.insert(DeferredPrepass); } ``` as can be seen in several of the example code updates here. There will probably also be instances where mutable `EntityCommands` vars no longer need to be mutable. |

Add AnimationGraph::from_clips and simplify animated_fox example (#14853)
# Objective Add a convenience constructor to make simple animation graphs easier to build. I've had some notes about attempting this since #11989 that I just remembered after seeing #14852. This partially addresses #14852, but I don't really know animation well enough to write all of the documentation it's asking for. ## Solution Add `AnimationGraph::from_clips` and use it to simplify `animated_fox`. Do some other little bits of incidental cleanup and documentation . ## Testing I ran `cargo run --example animated_fox`. |

Disallow empty cubic and rational curves (#14382)
# Objective
Previously, our cubic spline constructors would produce
`CubicCurve`/`RationalCurve` output with no data when they themselves
didn't hold enough control points to produce a well-formed curve.
Attempting to sample the resulting empty "curves" (e.g. by calling
`CubicCurve::position`) would crash the program (😓).
The objectives of this PR are:
1. Ensure that the curve output of `bevy_math`'s spline constructions
are never invalid as data.
2. Provide a type-level guarantee that `CubicCurve` and `RationalCurve`
actually function as curves.
## Solution
This has a few pieces. Firstly, the curve generator traits
`CubicGenerator`, `CyclicCubicGenerator`, and `RationalGenerator` are
now fallible — they have associated error types, and the
curve-generation functions are allowed to fail:
```rust
/// Implement this on cubic splines that can generate a cubic curve from their spline parameters.
pub trait CubicGenerator<P: VectorSpace> {
/// An error type indicating why construction might fail.
type Error;
/// Build a [`CubicCurve`] by computing the interpolation coefficients for each curve segment.
fn to_curve(&self) -> Result<CubicCurve<P>, Self::Error>;
}
```
All existing spline constructions use this together with errors that
indicate when they didn't have the right control data and provide curves
which have at least one segment whenever they return an `Ok` variant.
Next, `CubicCurve` and `RationalCurve` have been blessed with a
guarantee that their internal array of segments (`segments`) is never
empty. In particular, this field is no longer public, so that invalid
curves cannot be built using struct instantiation syntax. To compensate
for this shortfall for users (in particular library authors who might
want to implement their own generators), there is a new method
`from_segments` on these for constructing a curve from a list of
segments, failing if the list is empty:
```rust
/// Create a new curve from a collection of segments. If the collection of segments is empty,
/// a curve cannot be built and `None` will be returned instead.
pub fn from_segments(segments: impl Into<Vec<CubicSegment<P>>>) -> Option<Self> { //... }
```
All existing methods on `CyclicCurve` and `CubicCurve` maintain the
invariant, so the direct construction of invalid values by users is
impossible.
## Testing
Run unit tests from `bevy_math::cubic_splines`. Additionally, run the
`cubic_splines` example and try to get it to crash using small numbers
of control points: it uses the fallible constructors directly, so if
invalid data is ever constructed, it is basically guaranteed to crash.
---
## Migration Guide
The `to_curve` method on Bevy's cubic splines is now fallible (returning
a `Result`), meaning that any existing calls will need to be updated by
handling the possibility of an error variant.
Similarly, any custom implementation of `CubicGenerator` or
`RationalGenerator` will need to be amended to include an `Error` type
and be made fallible itself.
Finally, the fields of `CubicCurve` and `RationalCurve` are now private,
so any direct constructions of these structs from segments will need to
be replaced with the new `CubicCurve::from_segments` and
`RationalCurve::from_segments` methods.
---
## Design
The main thing to justify here is the choice for the curve internals to
remain the same. After all, if they were able to cause crashes in the
first place, it's worth wondering why safeguards weren't put in place on
the types themselves to prevent that.
My view on this is that the problem was really that the internals of
these methods implicitly relied on the assumption that the value they
were operating on was *actually a curve*, when this wasn't actually
guaranteed. Now, it's possible to make a bunch of small changes inside
the curve struct methods to account for that, but I think that's worse
than just guaranteeing that the data is valid upstream — sampling is
about as hot a code path as we're going to get in this area, and hitting
an additional branch every time it happens just to check that the struct
contains valid data is probably a waste of resources.
Another way of phrasing this is that even if we're only interested in
solving the crashes, the curve's validity needs to be checked at some
point, and it's almost certainly better to do this once at the point of
construction than every time the curve is sampled.
In cases where the control data is supplied dynamically, users would
already have to deal with empty curve outputs basically not working.
Anecdotally, I ran into this while writing the `cubic_splines` example,
and I think the diff illustrates the improvement pretty nicely — the
code no longer has to anticipate whether the output will be good or not;
it just has to handle the `Result`.
The cost of all this, of course, is that we have to guarantee that the
new invariant is actually maintained whenever we extend the API.
However, for the most part, I don't expect users to want to do much
surgery on the internals of their curves anyway.

Remove redundant imports (#12817)
# Objective - There are several redundant imports in the tests and examples that are not caught by CI because additional flags need to be passed. ## Solution - Run `cargo check --workspace --tests` and `cargo check --workspace --examples`, then fix all warnings. - Add `test-check` to CI, which will be run in the check-compiles job. This should catch future warnings for tests. Examples are already checked, but I'm not yet sure why they weren't caught. ## Discussion - Should the `--tests` and `--examples` flags be added to CI, so this is caught in the future? - If so, #12818 will need to be merged first. It was also a warning raised by checking the examples, but I chose to split off into a separate PR. --------- Co-authored-by: François Mockers <francois.mockers@vleue.com> |

Move Point out of cubic splines module and expand it (#12747)
# Objective
Previously, the `Point` trait, which abstracts all of the operations of
a real vector space, was sitting in the submodule of `bevy_math` for
cubic splines. However, the trait has broader applications than merely
cubic splines, and we should use it when possible to avoid code
duplication when performing vector operations.
## Solution
`Point` has been moved into a new submodule in `bevy_math` named
`common_traits`. Furthermore, it has been renamed to `VectorSpace`,
which is more descriptive, and an additional trait `NormedVectorSpace`
has been introduced to expand the API to cover situations involving
geometry in addition to algebra. Additionally, `VectorSpace` itself now
requires a `ZERO` constant and `Neg`. It also supports a `lerp` function
as an automatic trait method.
Here is what that looks like:
```rust
/// A type that supports the mathematical operations of a real vector space, irrespective of dimension.
/// In particular, this means that the implementing type supports:
/// - Scalar multiplication and division on the right by elements of `f32`
/// - Negation
/// - Addition and subtraction
/// - Zero
///
/// Within the limitations of floating point arithmetic, all the following are required to hold:
/// - (Associativity of addition) For all `u, v, w: Self`, `(u + v) + w == u + (v + w)`.
/// - (Commutativity of addition) For all `u, v: Self`, `u + v == v + u`.
/// - (Additive identity) For all `v: Self`, `v + Self::ZERO == v`.
/// - (Additive inverse) For all `v: Self`, `v - v == v + (-v) == Self::ZERO`.
/// - (Compatibility of multiplication) For all `a, b: f32`, `v: Self`, `v * (a * b) == (v * a) * b`.
/// - (Multiplicative identity) For all `v: Self`, `v * 1.0 == v`.
/// - (Distributivity for vector addition) For all `a: f32`, `u, v: Self`, `(u + v) * a == u * a + v * a`.
/// - (Distributivity for scalar addition) For all `a, b: f32`, `v: Self`, `v * (a + b) == v * a + v * b`.
///
/// Note that, because implementing types use floating point arithmetic, they are not required to actually
/// implement `PartialEq` or `Eq`.
pub trait VectorSpace:
Mul<f32, Output = Self>
+ Div<f32, Output = Self>
+ Add<Self, Output = Self>
+ Sub<Self, Output = Self>
+ Neg
+ Default
+ Debug
+ Clone
+ Copy
{
/// The zero vector, which is the identity of addition for the vector space type.
const ZERO: Self;
/// Perform vector space linear interpolation between this element and another, based
/// on the parameter `t`. When `t` is `0`, `self` is recovered. When `t` is `1`, `rhs`
/// is recovered.
///
/// Note that the value of `t` is not clamped by this function, so interpolating outside
/// of the interval `[0,1]` is allowed.
#[inline]
fn lerp(&self, rhs: Self, t: f32) -> Self {
*self * (1. - t) + rhs * t
}
}
```
```rust
/// A type that supports the operations of a normed vector space; i.e. a norm operation in addition
/// to those of [`VectorSpace`]. Specifically, the implementor must guarantee that the following
/// relationships hold, within the limitations of floating point arithmetic:
/// - (Nonnegativity) For all `v: Self`, `v.norm() >= 0.0`.
/// - (Positive definiteness) For all `v: Self`, `v.norm() == 0.0` implies `v == Self::ZERO`.
/// - (Absolute homogeneity) For all `c: f32`, `v: Self`, `(v * c).norm() == v.norm() * c.abs()`.
/// - (Triangle inequality) For all `v, w: Self`, `(v + w).norm() <= v.norm() + w.norm()`.
///
/// Note that, because implementing types use floating point arithmetic, they are not required to actually
/// implement `PartialEq` or `Eq`.
pub trait NormedVectorSpace: VectorSpace {
/// The size of this element. The return value should always be nonnegative.
fn norm(self) -> f32;
/// The squared norm of this element. Computing this is often faster than computing
/// [`NormedVectorSpace::norm`].
#[inline]
fn norm_squared(self) -> f32 {
self.norm() * self.norm()
}
/// The distance between this element and another, as determined by the norm.
#[inline]
fn distance(self, rhs: Self) -> f32 {
(rhs - self).norm()
}
/// The squared distance between this element and another, as determined by the norm. Note that
/// this is often faster to compute in practice than [`NormedVectorSpace::distance`].
#[inline]
fn distance_squared(self, rhs: Self) -> f32 {
(rhs - self).norm_squared()
}
}
```
Furthermore, this PR also demonstrates the use of the
`NormedVectorSpace` combined API to implement `ShapeSample` for
`Triangle2d` and `Triangle3d` simultaneously. Such deduplication is one
of the drivers for developing these APIs.
---
## Changelog
- `Point` from `cubic_splines` becomes `VectorSpace`, exported as
`bevy::math::VectorSpace`.
- `VectorSpace` requires `Neg` and `VectorSpace::ZERO` in addition to
its existing prerequisites.
- Introduced public traits `bevy::math::NormedVectorSpace` for generic
geometry tasks involving vectors.
- Implemented `ShapeSample` for `Triangle2d` and `Triangle3d`.
## Migration Guide
Since `Point` no longer exists, any projects using it must switch to
`bevy::math::VectorSpace`. Additionally, third-party implementations of
this trait now require the `Neg` trait; the constant `VectorSpace::ZERO`
must be provided as well.
---
## Discussion
### Design considerations
Originally, the `NormedVectorSpace::norm` method was part of a separate
trait `Normed`. However, I think that was probably too broad and, more
importantly, the semantics of having it in `NormedVectorSpace` are much
clearer.
As it currently stands, the API exposed here is pretty minimal, and
there is definitely a lot more that we could do, but there are more
questions to answer along the way. As a silly example, we could
implement `NormedVectorSpace::length` as an alias for
`NormedVectorSpace::norm`, but this overlaps with methods in all of the
glam types, so we would want to make sure that the implementations are
effectively identical (for what it's worth, I think they are already).
### Future directions
One example of something that could belong in the `NormedVectorSpace`
API is normalization. Actually, such a thing previously existed on this
branch before I decided to shelve it because of concerns with namespace
collision. It looked like this:
```rust
/// This element, but normalized to norm 1 if possible. Returns an error when the reciprocal of
/// the element's norm is not finite.
#[inline]
#[must_use]
fn normalize(&self) -> Result<Self, NonNormalizableError> {
let reciprocal = 1.0 / self.norm();
if reciprocal.is_finite() {
Ok(*self * reciprocal)
} else {
Err(NonNormalizableError { reciprocal })
}
}
/// An error indicating that an element of a [`NormedVectorSpace`] was non-normalizable due to having
/// non-finite norm-reciprocal.
#[derive(Debug, Error)]
#[error("Element with norm reciprocal {reciprocal} cannot be normalized")]
pub struct NonNormalizableError {
reciprocal: f32
}
```
With this kind of thing in hand, it might be worth considering
eventually making the passage from vectors to directions fully generic
by employing a wrapper type. (Of course, for our concrete types, we
would leave the existing names in place as aliases.) That is, something
like:
```rust
pub struct NormOne<T>
where T: NormedVectorSpace { //... }
```
Utterly separately, the reason that I implemented `ShapeSample` for
`Triangle2d`/`Triangle3d` was to prototype uniform sampling of abstract
meshes, so that's also a future direction.

Implement the AnimationGraph, allowing for multiple animations to be blended together. (#11989)
This is an implementation of RFC #51: https://github.com/bevyengine/rfcs/blob/main/rfcs/51-animation-composition.md Note that the implementation strategy is different from the one outlined in that RFC, because two-phase animation has now landed. # Objective Bevy needs animation blending. The RFC for this is [RFC 51]. ## Solution This is an implementation of the RFC. Note that the implementation strategy is different from the one outlined there, because two-phase animation has now landed. This is just a draft to get the conversation started. Currently we're missing a few things: - [x] A fully-fleshed-out mechanism for transitions - [x] A serialization format for `AnimationGraph`s - [x] Examples are broken, other than `animated_fox` - [x] Documentation --- ## Changelog ### Added * The `AnimationPlayer` has been reworked to support blending multiple animations together through an `AnimationGraph`, and as such will no longer function unless a `Handle<AnimationGraph>` has been added to the entity containing the player. See [RFC 51] for more details. * Transition functionality has moved from the `AnimationPlayer` to a new component, `AnimationTransitions`, which works in tandem with the `AnimationGraph`. ## Migration Guide * `AnimationPlayer`s can no longer play animations by themselves and need to be paired with a `Handle<AnimationGraph>`. Code that was using `AnimationPlayer` to play animations will need to create an `AnimationGraph` asset first, add a node for the clip (or clips) you want to play, and then supply the index of that node to the `AnimationPlayer`'s `play` method. * The `AnimationPlayer::play_with_transition()` method has been removed and replaced with the `AnimationTransitions` component. If you were previously using `AnimationPlayer::play_with_transition()`, add all animations that you were playing to the `AnimationGraph`, and create an `AnimationTransitions` component to manage the blending between them.

Migrate from LegacyColor to bevy_color::Color (#12163)
# Objective - As part of the migration process we need to a) see the end effect of the migration on user ergonomics b) check for serious perf regressions c) actually migrate the code - To accomplish this, I'm going to attempt to migrate all of the remaining user-facing usages of `LegacyColor` in one PR, being careful to keep a clean commit history. - Fixes #12056. ## Solution I've chosen to use the polymorphic `Color` type as our standard user-facing API. - [x] Migrate `bevy_gizmos`. - [x] Take `impl Into<Color>` in all `bevy_gizmos` APIs - [x] Migrate sprites - [x] Migrate UI - [x] Migrate `ColorMaterial` - [x] Migrate `MaterialMesh2D` - [x] Migrate fog - [x] Migrate lights - [x] Migrate StandardMaterial - [x] Migrate wireframes - [x] Migrate clear color - [x] Migrate text - [x] Migrate gltf loader - [x] Register color types for reflection - [x] Remove `LegacyColor` - [x] Make sure CI passes Incidental improvements to ease migration: - added `Color::srgba_u8`, `Color::srgba_from_array` and friends - added `set_alpha`, `is_fully_transparent` and `is_fully_opaque` to the `Alpha` trait - add and immediately deprecate (lol) `Color::rgb` and friends in favor of more explicit and consistent `Color::srgb` - standardized on white and black for most example text colors - added vector field traits to `LinearRgba`: ~~`Add`, `Sub`, `AddAssign`, `SubAssign`,~~ `Mul<f32>` and `Div<f32>`. Multiplications and divisions do not scale alpha. `Add` and `Sub` have been cut from this PR. - added `LinearRgba` and `Srgba` `RED/GREEN/BLUE` - added `LinearRgba_to_f32_array` and `LinearRgba::to_u32` ## Migration Guide Bevy's color types have changed! Wherever you used a `bevy::render::Color`, a `bevy::color::Color` is used instead. These are quite similar! Both are enums storing a color in a specific color space (or to be more precise, using a specific color model). However, each of the different color models now has its own type. TODO... - `Color::rgba`, `Color::rgb`, `Color::rbga_u8`, `Color::rgb_u8`, `Color::rgb_from_array` are now `Color::srgba`, `Color::srgb`, `Color::srgba_u8`, `Color::srgb_u8` and `Color::srgb_from_array`. - `Color::set_a` and `Color::a` is now `Color::set_alpha` and `Color::alpha`. These are part of the `Alpha` trait in `bevy_color`. - `Color::is_fully_transparent` is now part of the `Alpha` trait in `bevy_color` - `Color::r`, `Color::set_r`, `Color::with_r` and the equivalents for `g`, `b` `h`, `s` and `l` have been removed due to causing silent relatively expensive conversions. Convert your `Color` into the desired color space, perform your operations there, and then convert it back into a polymorphic `Color` enum. - `Color::hex` is now `Srgba::hex`. Call `.into` or construct a `Color::Srgba` variant manually to convert it. - `WireframeMaterial`, `ExtractedUiNode`, `ExtractedDirectionalLight`, `ExtractedPointLight`, `ExtractedSpotLight` and `ExtractedSprite` now store a `LinearRgba`, rather than a polymorphic `Color` - `Color::rgb_linear` and `Color::rgba_linear` are now `Color::linear_rgb` and `Color::linear_rgba` - The various CSS color constants are no longer stored directly on `Color`. Instead, they're defined in the `Srgba` color space, and accessed via `bevy::color::palettes::css`. Call `.into()` on them to convert them into a `Color` for quick debugging use, and consider using the much prettier `tailwind` palette for prototyping. - The `LIME_GREEN` color has been renamed to `LIMEGREEN` to comply with the standard naming. - Vector field arithmetic operations on `Color` (add, subtract, multiply and divide by a f32) have been removed. Instead, convert your colors into `LinearRgba` space, and perform your operations explicitly there. This is particularly relevant when working with emissive or HDR colors, whose color channel values are routinely outside of the ordinary 0 to 1 range. - `Color::as_linear_rgba_f32` has been removed. Call `LinearRgba::to_f32_array` instead, converting if needed. - `Color::as_linear_rgba_u32` has been removed. Call `LinearRgba::to_u32` instead, converting if needed. - Several other color conversion methods to transform LCH or HSL colors into float arrays or `Vec` types have been removed. Please reimplement these externally or open a PR to re-add them if you found them particularly useful. - Various methods on `Color` such as `rgb` or `hsl` to convert the color into a specific color space have been removed. Convert into `LinearRgba`, then to the color space of your choice. - Various implicitly-converting color value methods on `Color` such as `r`, `g`, `b` or `h` have been removed. Please convert it into the color space of your choice, then check these properties. - `Color` no longer implements `AsBindGroup`. Store a `LinearRgba` internally instead to avoid conversion costs. --------- Co-authored-by: Alice Cecile <alice.i.cecil@gmail.com> Co-authored-by: Afonso Lage <lage.afonso@gmail.com> Co-authored-by: Rob Parrett <robparrett@gmail.com> Co-authored-by: Zachary Harrold <zac@harrold.com.au> |

Improve lighting in more examples (#12021)
# Objective - #11868 changed the lighting system, forcing lights to increase their intensity. The PR fixed most examples, but missed a few. These I later caught in https://github.com/bevyengine/bevy-website/pull/1023. - Related: #11982, #11981. - While there, I noticed that the spotlight example could use a few easy improvements. ## Solution - Increase lighting in `skybox`, `spotlight`, `animated_transform`, and `gltf_skinned_mesh`. - Improve spotlight example. - Make ground plane move with cubes, so they don't phase into each other. - Batch spawn cubes. - Add controls text. - Change controls to allow rotating around spotlights. ## Showcase ### Skybox Before: <img width="1392" alt="image" src="https://github.com/bevyengine/bevy/assets/59022059/8ba00d74-6d68-4414-97a8-28afb8305570"> After: <img width="1392" alt="image" src="https://github.com/bevyengine/bevy/assets/59022059/ad15c471-6979-4dda-9889-9189136d8404"> ### Spotlight Before: <img width="1392" alt="image" src="https://github.com/bevyengine/bevy/assets/59022059/53f966de-acf3-46b8-8299-0005c4cb8da0"> After: <img width="1392" alt="image" src="https://github.com/bevyengine/bevy/assets/59022059/05c73c1e-0739-4226-83d6-e4249a9105e0"> ### Animated Transform Before: <img width="1392" alt="image" src="https://github.com/bevyengine/bevy/assets/59022059/6d7d4ea0-e22e-42a5-9905-ea1731d474cf"> After: <img width="1392" alt="image" src="https://github.com/bevyengine/bevy/assets/59022059/f1ee08d6-d17a-4391-91a6-d903b9fbdc3c"> ### gLTF Skinned Mesh Before: <img width="1392" alt="image" src="https://github.com/bevyengine/bevy/assets/59022059/547569a6-d13b-4fe0-a8c1-e11f02c4f9a2"> After: <img width="1392" alt="image" src="https://github.com/bevyengine/bevy/assets/59022059/34517aba-09e4-4e9b-982a-a4a8b893c48a"> --- ## Changelog - Increased lighting in `skybox`, `spotlight`, `animated_transform`, and `gltf_skinned_mesh` examples. - Improved usability of `spotlight` example. |

Rename bevy_render::Color to LegacyColor (#12069)
# Objective The migration process for `bevy_color` (#12013) will be fairly involved: there will be hundreds of affected files, and a large number of APIs. ## Solution To allow us to proceed granularly, we're going to keep both `bevy_color::Color` (new) and `bevy_render::Color` (old) around until the migration is complete. However, simply doing this directly is confusing! They're both called `Color`, making it very hard to tell when a portion of the code has been ported. As discussed in #12056, by renaming the old `Color` type, we can make it easier to gradually migrate over, one API at a time. ## Migration Guide THIS MIGRATION GUIDE INTENTIONALLY LEFT BLANK. This change should not be shipped to end users: delete this section in the final migration guide! --------- Co-authored-by: Alice Cecile <alice.i.cecil@gmail.com> |

Rework animation to be done in two phases. (#11707)
# Objective Bevy's animation system currently does tree traversals based on `Name` that aren't necessary. Not only do they require in unsafe code because tree traversals are awkward with parallelism, but they are also somewhat slow, brittle, and complex, which manifested itself as way too many queries in #11670. # Solution Divide animation into two phases: animation *advancement* and animation *evaluation*, which run after one another. *Advancement* operates on the `AnimationPlayer` and sets the current animation time to match the game time. *Evaluation* operates on all animation bones in the scene in parallel and sets the transforms and/or morph weights based on the time and the clip. To do this, we introduce a new component, `AnimationTarget`, which the asset loader places on every bone. It contains the ID of the entity containing the `AnimationPlayer`, as well as a UUID that identifies which bone in the animation the target corresponds to. In the case of glTF, the UUID is derived from the full path name to the bone. The rule that `AnimationTarget`s are descendants of the entity containing `AnimationPlayer` is now just a convention, not a requirement; this allows us to eliminate the unsafe code. # Migration guide * `AnimationClip` now uses UUIDs instead of hierarchical paths based on the `Name` component to refer to bones. This has several consequences: - A new component, `AnimationTarget`, should be placed on each bone that you wish to animate, in order to specify its UUID and the associated `AnimationPlayer`. The glTF loader automatically creates these components as necessary, so most uses of glTF rigs shouldn't need to change. - Moving a bone around the tree, or renaming it, no longer prevents an `AnimationPlayer` from affecting it. - Dynamically changing the `AnimationPlayer` component will likely require manual updating of the `AnimationTarget` components. * Entities with `AnimationPlayer` components may now possess descendants that also have `AnimationPlayer` components. They may not, however, animate the same bones. * As they aren't specific to `TypeId`s, `bevy_reflect::utility::NoOpTypeIdHash` and `bevy_reflect::utility::NoOpTypeIdHasher` have been renamed to `bevy_reflect::utility::NoOpHash` and `bevy_reflect::utility::NoOpHasher` respectively. |

New Exposure and Lighting Defaults (and calibrate examples) (#11868)
# Objective After adding configurable exposure, we set the default ev100 value to `7` (indoor). This brought us out of sync with Blender's configuration and defaults. This PR changes the default to `9.7` (bright indoor or very overcast outdoors), as I calibrated in #11577. This feels like a very reasonable default. The other changes generally center around tweaking Bevy's lighting defaults and examples to play nicely with this number, alongside a few other tweaks and improvements. Note that for artistic reasons I have reverted some examples, which changed to directional lights in #11581, back to point lights. Fixes #11577 --- ## Changelog - Changed `Exposure::ev100` from `7` to `9.7` to better match Blender - Renamed `ExposureSettings` to `Exposure` - `Camera3dBundle` now includes `Exposure` for discoverability - Bumped `FULL_DAYLIGHT ` and `DIRECT_SUNLIGHT` to represent the middle-to-top of those ranges instead of near the bottom - Added new `AMBIENT_DAYLIGHT` constant and set that as the new `DirectionalLight` default illuminance. - `PointLight` and `SpotLight` now have a default `intensity` of 1,000,000 lumens. This makes them actually useful in the context of the new "semi-outdoor" exposure and puts them in the "cinema lighting" category instead of the "common household light" category. They are also reasonably close to the Blender default. - `AmbientLight` default has been bumped from `20` to `80`. ## Migration Guide - The increased `Exposure::ev100` means that all existing 3D lighting will need to be adjusted to match (DirectionalLights, PointLights, SpotLights, EnvironmentMapLights, etc). Or alternatively, you can adjust the `Exposure::ev100` on your cameras to work nicely with your current lighting values. If you are currently relying on default intensity values, you might need to change the intensity to achieve the same effect. Note that in Bevy 0.12, point/spot lights had a different hard coded ev100 value than directional lights. In Bevy 0.13, they use the same ev100, so if you have both in your scene, the _scale_ between these light types has changed and you will likely need to adjust one or both of them. |

Change light defaults & fix light examples (#11581)
# Objective Fix https://github.com/bevyengine/bevy/issues/11577. ## Solution Fix the examples, add a few constants to make setting light values easier, and change the default lighting settings to be more realistic. (Now designed for an overcast day instead of an indoor environment) --- I did not include any example-related changes in here. ## Changelogs (not including breaking changes) ### bevy_pbr - Added `light_consts` module (included in prelude), which contains common lux and lumen values for lights. - Added `AmbientLight::NONE` constant, which is an ambient light with a brightness of 0. - Added non-EV100 variants for `ExposureSettings`'s EV100 constants, which allow easier construction of an `ExposureSettings` from a EV100 constant. ## Breaking changes ### bevy_pbr The several default lighting values were changed: - `PointLight`'s default `intensity` is now `2000.0` - `SpotLight`'s default `intensity` is now `2000.0` - `DirectionalLight`'s default `illuminance` is now `light_consts::lux::OVERCAST_DAY` (`1000.`) - `AmbientLight`'s default `brightness` is now `20.0` |

Deprecate shapes in bevy_render::mesh::shape (#11773)
# Objective #11431 and #11688 implemented meshing support for Bevy's new geometric primitives. The next step is to deprecate the shapes in `bevy_render::mesh::shape` and to later remove them completely for 0.14. ## Solution Deprecate the shapes and reduce code duplication by utilizing the primitive meshing API for the old shapes where possible. Note that some shapes have behavior that can't be exactly reproduced with the new primitives yet: - `Box` is more of an AABB with min/max extents - `Plane` supports a subdivision count - `Quad` has a `flipped` property These types have not been changed to utilize the new primitives yet. --- ## Changelog - Deprecated all shapes in `bevy_render::mesh::shape` - Changed all examples to use new primitives for meshing ## Migration Guide Bevy has previously used rendering-specific types like `UVSphere` and `Quad` for primitive mesh shapes. These have now been deprecated to use the geometric primitives newly introduced in version 0.13. Some examples: ```rust let before = meshes.add(shape::Box::new(5.0, 0.15, 5.0)); let after = meshes.add(Cuboid::new(5.0, 0.15, 5.0)); let before = meshes.add(shape::Quad::default()); let after = meshes.add(Rectangle::default()); let before = meshes.add(shape::Plane::from_size(5.0)); // The surface normal can now also be specified when using `new` let after = meshes.add(Plane3d::default().mesh().size(5.0, 5.0)); let before = meshes.add( Mesh::try_from(shape::Icosphere { radius: 0.5, subdivisions: 5, }) .unwrap(), ); let after = meshes.add(Sphere::new(0.5).mesh().ico(5).unwrap()); ``` |

Mesh insert indices (#11745)

RenderAssetPersistencePolicy → RenderAssetUsages (#11399)
# Objective Right now, all assets in the main world get extracted and prepared in the render world (if the asset's using the RenderAssetPlugin). This is unfortunate for two cases: 1. **TextureAtlas** / **FontAtlas**: This one's huge. The individual `Image` assets that make up the atlas are cloned and prepared individually when there's no reason for them to be. The atlas textures are built on the CPU in the main world. *There can be hundreds of images that get prepared for rendering only not to be used.* 2. If one loads an Image and needs to transform it in a system before rendering it, kind of like the [decompression example](https://github.com/bevyengine/bevy/blob/main/examples/asset/asset_decompression.rs#L120), there's a price paid for extracting & preparing the asset that's not intended to be rendered yet. ------ * References #10520 * References #1782 ## Solution This changes the `RenderAssetPersistencePolicy` enum to bitflags. I felt that the objective with the parameter is so similar in nature to wgpu's [`TextureUsages`](https://docs.rs/wgpu/latest/wgpu/struct.TextureUsages.html) and [`BufferUsages`](https://docs.rs/wgpu/latest/wgpu/struct.BufferUsages.html), that it may as well be just like that. ```rust // This asset only needs to be in the main world. Don't extract and prepare it. RenderAssetUsages::MAIN_WORLD // Keep this asset in the main world and RenderAssetUsages::MAIN_WORLD | RenderAssetUsages::RENDER_WORLD // This asset is only needed in the render world. Remove it from the asset server once extracted. RenderAssetUsages::RENDER_WORLD ``` ### Alternate Solution I considered introducing a third field to `RenderAssetPersistencePolicy` enum: ```rust enum RenderAssetPersistencePolicy { /// Keep the asset in the main world after extracting to the render world. Keep, /// Remove the asset from the main world after extracting to the render world. Unload, /// This doesn't need to be in the render world at all. NoExtract, // <----- } ``` Functional, but this seemed like shoehorning. Another option is renaming the enum to something like: ```rust enum RenderAssetExtractionPolicy { /// Extract the asset and keep it in the main world. Extract, /// Remove the asset from the main world after extracting to the render world. ExtractAndUnload, /// This doesn't need to be in the render world at all. NoExtract, } ``` I think this last one could be a good option if the bitflags are too clunky. ## Migration Guide * `RenderAssetPersistencePolicy::Keep` → `RenderAssetUsage::MAIN_WORLD | RenderAssetUsage::RENDER_WORLD` (or `RenderAssetUsage::default()`) * `RenderAssetPersistencePolicy::Unload` → `RenderAssetUsage::RENDER_WORLD` * For types implementing the `RenderAsset` trait, change `fn persistence_policy(&self) -> RenderAssetPersistencePolicy` to `fn asset_usage(&self) -> RenderAssetUsages`. * Change any references to `cpu_persistent_access` (`RenderAssetPersistencePolicy`) to `asset_usage` (`RenderAssetUsage`). This applies to `Image`, `Mesh`, and a few other types. |

Exposure settings (adopted) (#11347)
Rebased and finished version of https://github.com/bevyengine/bevy/pull/8407. Huge thanks to @GitGhillie for adjusting all the examples, and the many other people who helped write this PR (@superdump , @coreh , among others) :) Fixes https://github.com/bevyengine/bevy/issues/8369 --- ## Changelog - Added a `brightness` control to `Skybox`. - Added an `intensity` control to `EnvironmentMapLight`. - Added `ExposureSettings` and `PhysicalCameraParameters` for controlling exposure of 3D cameras. - Removed the baked-in `DirectionalLight` exposure Bevy previously hardcoded internally. ## Migration Guide - If using a `Skybox` or `EnvironmentMapLight`, use the new `brightness` and `intensity` controls to adjust their strength. - All 3D scene will now have different apparent brightnesses due to Bevy implementing proper exposure controls. You will have to adjust the intensity of your lights and/or your camera exposure via the new `ExposureSettings` component to compensate. --------- Co-authored-by: Robert Swain <robert.swain@gmail.com> Co-authored-by: GitGhillie <jillisnoordhoek@gmail.com> Co-authored-by: Marco Buono <thecoreh@gmail.com> Co-authored-by: vero <email@atlasdostal.com> Co-authored-by: atlas dostal <rodol@rivalrebels.com> |

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.

Unload render assets from RAM (#10520)
# Objective - No point in keeping Meshes/Images in RAM once they're going to be sent to the GPU, and kept in VRAM. This saves a _significant_ amount of memory (several GBs) on scenes like bistro. - References - https://github.com/bevyengine/bevy/pull/1782 - https://github.com/bevyengine/bevy/pull/8624 ## Solution - Augment RenderAsset with the capability to unload the underlying asset after extracting to the render world. - Mesh/Image now have a cpu_persistent_access field. If this field is RenderAssetPersistencePolicy::Unload, the asset will be unloaded from Assets<T>. - A new AssetEvent is sent upon dropping the last strong handle for the asset, which signals to the RenderAsset to remove the GPU version of the asset. --- ## Changelog - Added `AssetEvent::NoLongerUsed` and `AssetEvent::is_no_longer_used()`. This event is sent when the last strong handle of an asset is dropped. - Rewrote the API for `RenderAsset` to allow for unloading the asset data from the CPU. - Added `RenderAssetPersistencePolicy`. - Added `Mesh::cpu_persistent_access` for memory savings when the asset is not needed except for on the GPU. - Added `Image::cpu_persistent_access` for memory savings when the asset is not needed except for on the GPU. - Added `ImageLoaderSettings::cpu_persistent_access`. - Added `ExrTextureLoaderSettings`. - Added `HdrTextureLoaderSettings`. ## Migration Guide - Asset loaders (GLTF, etc) now load meshes and textures without `cpu_persistent_access`. These assets will be removed from `Assets<Mesh>` and `Assets<Image>` once `RenderAssets<Mesh>` and `RenderAssets<Image>` contain the GPU versions of these assets, in order to reduce memory usage. If you require access to the asset data from the CPU in future frames after the GLTF asset has been loaded, modify all dependent `Mesh` and `Image` assets and set `cpu_persistent_access` to `RenderAssetPersistencePolicy::Keep`. - `Mesh` now requires a new `cpu_persistent_access` field. Set it to `RenderAssetPersistencePolicy::Keep` to mimic the previous behavior. - `Image` now requires a new `cpu_persistent_access` field. Set it to `RenderAssetPersistencePolicy::Keep` to mimic the previous behavior. - `MorphTargetImage::new()` now requires a new `cpu_persistent_access` parameter. Set it to `RenderAssetPersistencePolicy::Keep` to mimic the previous behavior. - `DynamicTextureAtlasBuilder::add_texture()` now requires that the `TextureAtlas` you pass has an `Image` with `cpu_persistent_access: RenderAssetPersistencePolicy::Keep`. Ensure you construct the image properly for the texture atlas. - The `RenderAsset` trait has significantly changed, and requires adapting your existing implementations. - The trait now requires `Clone`. - The `ExtractedAsset` associated type has been removed (the type itself is now extracted). - The signature of `prepare_asset()` is slightly different - A new `persistence_policy()` method is now required (return RenderAssetPersistencePolicy::Unload to match the previous behavior). - Match on the new `NoLongerUsed` variant for exhaustive matches of `AssetEvent`. |

Replace or document ignored doctests (#11040)
# Objective There are a lot of doctests that are `ignore`d for no documented reason. And that should be fixed. ## Solution I searched the bevy repo with the regex ` ```[a-z,]*ignore ` in order to find all `ignore`d doctests. For each one of the `ignore`d doctests, I did the following steps: 1. Attempt to remove the `ignored` attribute while still passing the test. I did this by adding hidden dummy structs and imports. 2. If step 1 doesn't work, attempt to replace the `ignored` attribute with the `no_run` attribute while still passing the test. 3. If step 2 doesn't work, keep the `ignored` attribute but add documentation for why the `ignored` attribute was added. --------- Co-authored-by: François <mockersf@gmail.com> |

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. |

Add consuming builder methods for more ergonomic Mesh creation (#10056)
# Objective
- This PR aims to make creating meshes a little bit more ergonomic,
specifically by removing the need for intermediate mutable variables.
## Solution
- We add methods that consume the `Mesh` and return a mesh with the
specified changes, so that meshes can be entirely constructed via
builder-style calls, without intermediate variables;
- Methods are flagged with `#[must_use]` to ensure proper use;
- Examples are updated to use the new methods where applicable. Some
examples are kept with the mutating methods so that users can still
easily discover them, and also where the new methods wouldn't really be
an improvement.
## Examples
Before:
```rust
let mut mesh = Mesh::new(PrimitiveTopology::TriangleList);
mesh.insert_attribute(Mesh::ATTRIBUTE_POSITION, vs);
mesh.insert_attribute(Mesh::ATTRIBUTE_NORMAL, vns);
mesh.insert_attribute(Mesh::ATTRIBUTE_UV_0, vts);
mesh.set_indices(Some(Indices::U32(tris)));
mesh
```
After:
```rust
Mesh::new(PrimitiveTopology::TriangleList)
.with_inserted_attribute(Mesh::ATTRIBUTE_POSITION, vs)
.with_inserted_attribute(Mesh::ATTRIBUTE_NORMAL, vns)
.with_inserted_attribute(Mesh::ATTRIBUTE_UV_0, vts)
.with_indices(Some(Indices::U32(tris)))
```
Before:
```rust
let mut cube = Mesh::from(shape::Cube { size: 1.0 });
cube.generate_tangents().unwrap();
PbrBundle {
mesh: meshes.add(cube),
..default()
}
```
After:
```rust
PbrBundle {
mesh: meshes.add(
Mesh::from(shape::Cube { size: 1.0 })
.with_generated_tangents()
.unwrap(),
),
..default()
}
```
---
## Changelog
- Added consuming builder methods for more ergonomic `Mesh` creation:
`with_inserted_attribute()`, `with_removed_attribute()`,
`with_indices()`, `with_duplicated_vertices()`,
`with_computed_flat_normals()`, `with_generated_tangents()`,
`with_morph_targets()`, `with_morph_target_names()`.
