Free at last!
# Objective
- Using `.system()` is no longer needed anywhere, and anyone using it will have already gotten a deprecation warning.
- https://github.com/bevyengine/bevy/pull/3302 was a super special case for `.system()`, since it was so prevelant. However, that's no reason.
- Despite it being deprecated, another couple of uses of it have already landed, including in the deprecating PR.
- These have all been because of doc examples having warnings not breaking CI - 🎟️?
## Solution
- Remove it.
- It's gone
---
## Changelog
- You can no longer use `.system()`
## Migration Guide
- You can no longer use `.system()`. It was deprecated in 0.7.0, and you should have followed the deprecation warning then. You can just remove the method call.
- Thanks to the @TheRawMeatball for producing
# Objective
We are currently asking contributors to "skip" optional sections, which is a bit confusing. "Skip" can be taken to mean that you should "leave that section alone" and result in these bits of template being left in the PR description.
## Solution
Let contributors know that it's okay to delete the section if it's not needed.
# Objective
- Fix `ClusterConfig::None`
- This fix is from @robtfm but they didn't have time to submit it, so I am.
## Solution
- Always clear clusters and skip processing when `ClusterConfig::None`
- Conditionally remove `VisiblePointLights` from the view if it is present
# Objective
- https://github.com/bevyengine/bevy/pull/4098 still hasn't fixed minimisation on Windows.
- `Clusters.lights` is assumed to have the number of items given by the product of `Clusters.dimensions`'s axes.
## Solution
- Make that true in `clear`.
# Objective
- Fixes#4234
- Fixes#4473
- Built on top of #3989
- Improve performance of `assign_lights_to_clusters`
## Solution
- Remove the OBB-based cluster light assignment algorithm and calculation of view space AABBs
- Implement the 'iterative sphere refinement' algorithm used in Just Cause 3 by Emil Persson as documented in the Siggraph 2015 Practical Clustered Shading talk by Persson, on pages 42-44 http://newq.net/dl/pub/s2015_practical.pdf
- Adapt to also support orthographic projections
- Add `many_lights -- orthographic` for testing many lights using an orthographic projection
## Results
- `assign_lights_to_clusters` in `many_lights` before this PR on an M1 Max over 1500 frames had a median execution time of 1.71ms. With this PR it is 1.51ms, a reduction of 0.2ms or 11.7% for this system.

# Objective
- in #3851, a feature for tracing was added to bevy_transform
- usage of that feature was moved to bevy_hierarchy, but the feature was not updated
## Solution
- add the feature to bevy_hierarchy, remove it from bevy_transform
# Objective
Continue the effort to clean up this example
## Solution
- Store contributor name as component to avoid awkward vec of tuples
- Name the variable storing the Random Number Generator "rng"
- Use init_resource for resource implementing default
- Fix a few spots where an Entity was unnecessarily referenced and immediately dereferenced
- Fix up an awkward comment
# Objective
- Provide more information when despawning an entity
## Solution
- Add a debug log when despawning an entity
- Add spans to the recursive ways of despawning an entity
```sh
RUST_LOG=debug cargo run --example panic --features trace
# RUST_LOG=debug needed to show debug logs from bevy_ecs
# --features trace needed to have the extra spans
...
DEBUG bevy_app:frame:stage{name=Update}:system_commands{name="panic::despawn_parent"}:command{name="DespawnRecursive" entity=0v0}: bevy_ecs::world: Despawning entity 1v0
DEBUG bevy_app:frame:stage{name=Update}:system_commands{name="panic::despawn_parent"}:command{name="DespawnRecursive" entity=0v0}: bevy_ecs::world: Despawning entity 0v0
```
## Objective
Fixes#4122.
## Solution
Inherit the visibility of the struct being derived for the `xxItem`, `xxFetch`, `xxState` structs.
Co-authored-by: Carter Anderson <mcanders1@gmail.com>
# Objective
The documentation of the `Time::last_update` and `Time::time_since_startup` methods contains typos. It uses apostrophe instead of backtick characters around `Instant` and `Duration`, so that these words are not recognized as identifiers in the generated API documentation. This should be fixed.
## Solution
Fix the typos.
# Objective
Fixes https://github.com/bevyengine/bevy/issues/3499
## Solution
Uses a `HashMap` from `RenderTarget` to sampled textures when preparing `ViewTarget`s to ensure that two passes with the same render target get sampled to the same texture.
This builds on and depends on https://github.com/bevyengine/bevy/pull/3412, so this will be a draft PR until #3412 is merged. All changes for this PR are in the last commit.
# Objective
glTF files can contain cameras. Currently the scene viewer example uses _a_ camera defined in the file if possible, otherwise it spawns a new one. It would be nice if instead it could load all the cameras and cycle through them, while also having a separate user-controller camera.
## Solution
- instead of just a camera that is already defined, always spawn a new separate user-controller camera
- maintain a list of loaded cameras and cycle through them (wrapping to the user-controller camera) when pressing `C`
This matches the behavious that https://github.khronos.org/glTF-Sample-Viewer-Release/ has.
## Implementation notes
- The gltf scene asset loader just spawns the cameras into the world, but does not return a mapping of camera index to bevy entity. So instead the scene_viewer example just collects all spawned cameras with a good old `query.iter().collect()`, so the order is unspecified and may change between runs.

# Objective
- Several examples are useful for qualitative tests of Bevy's performance
- By contrast, these are less useful for learning material: they are often relatively complex and have large amounts of setup and are performance optimized.
## Solution
- Move bevymark, many_sprites and many_cubes into the new stress_tests example folder
- Move contributors into the games folder: unlike the remaining examples in the 2d folder, it is not focused on demonstrating a clear feature.
# Objective
- While playing with volume, I noticed that when setting the volume just after playback start, I still get a few milliseconds at normal volume
## Solution
- Replace `play_in_loop` with `play_with_settings` that allows from more controls
- Adds a `PlaybackSettings` to specify the settings from start. Can be used: `PlaybackSettings::LOOP.with_volume(0.75)`
Currently `tracy` interprets the entire trace as one frame because the marker for frames isn't being recorded.
~~When an event with `tracy.trace_marker=true` is recorded, `tracing-tracy` will mark the frame as finished:
<aa0b96b2ae/tracing-tracy/src/lib.rs (L240)>~~
~~Unfortunately this leads to~~
```rs
INFO bevy_app:frame: bevy_app::app: finished frame tracy.frame_mark=true
```
~~being printed every frame (we can't use DEBUG because bevy_log sets `max_release_level_info`.~~
Instead of emitting an event that gets logged every frame, we can depend on tracy-client itself and call `finish_continuous_frame!();`
# Objective
- Fixes the issue with orthographic camera imported from glTF not displaying anything (mentioned in #4005).
## Solution
- This was due to wrong scaling mode being used. This PR simply changes WindowSize scaling mode to FixedHorizontal.
## Important Note
Currently, othographic scale in Blender, three.js, and possibly other software does not translate to Bevy (via glTF) because their developers have [misinterpreted the spec](https://github.com/KhronosGroup/glTF/issues/1663#issuecomment-618194015). The camera parameters have been clarified in glTF 2.0, which was released on October of 2021. In Blender 3.0.1 this issue has **not** been fixed yet. If you are importing orthographic cameras from Blender, you have to divide the scale by 2.
# Objective
- Previously, `iter_combinations()` does not work on queries that have filters.
- Fixes#3651
## Solution
- Derived Copy on all `*Fetch<T>` structs, and manually implemented `Clone` to allow the test to pass (`.count()` does not work on `QueryCombinationIter` when `Clone` is derived)

# Objective
- Make `set_active_camera` system correctly respond to camera deletion, while preserving its correct behavior on first ever frame and any consequent frame, and with multiple cameras of the same type available in the world.
- Fixes#4227
## Solution
- Add a check that the entity referred to by `ActiveCamera` still exists in the world.
# Objective
- In glTF, mesh can be named. This named is used to be able to reference the mesh, but not as a component on the entity
- Bevy only added the node name to the parent node.
## Solution
- Also adds the name on the mesh entity if there is one.
Limitation: In glTF, it's possible to have one mesh (which can be named) corresponding to several primitives (which can't, but are the actual mesh). I added the mesh name to the entity with the `PbrBundle` matching the primitives, which means that a mesh with several primitives would all have the same name. I think this is acceptable...
# Objective
- Make it possible to use `System`s outside of the scheduler/executor without having to define logic to track new archetypes and call `System::add_archetype()` for each.
## Solution
- Replace `System::add_archetype(&Archetype)` with `System::update_archetypes(&World)`, making systems responsible for tracking their own most recent archetype generation the way that `SystemState` already does.
This has minimal (or simplifying) effect on most of the code with the exception of `FunctionSystem`, which must now track the latest `ArchetypeGeneration` it saw instead of relying on the executor to do it.

# Objective
Fixes#4193
## Solution
When resetting a node's `Interaction` to `None`, ignore any `Clicked` node because that should be handled by the mouse release check exclusively.
Remove the 'chaining' api, as it's peculiar
~~Implement the label traits for `Box<dyn ThatTrait>` (n.b. I'm not confident about this change, but it was the quickest path to not regressing)~~
Remove the need for '`.system`' when using run criteria piping
# 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
- ~~Use `Vec` instead of a `SmallVec`~~
- ~~Don't use an temporary variable~~
- Compute the affine matrix as an `Affine3A` instead
- Remove the `temp` vec
| |mean|
|---|---|
|base|15.17ms|
|~~vec~~|~~9.31ms~~|
|~~no temp variable~~|~~11.31ms~~|
|removing the temp vector|8.43ms|
|affine|13.21ms|
|all together|7.23ms|
# Objective
- Make use of storage buffers, where they are available, for clustered forward bindings to support far more point lights in a scene
- Fixes#3605
- Based on top of #4079
This branch on an M1 Max can keep 60fps with about 2150 point lights of radius 1m in the Sponza scene where I've been testing. The bottleneck is mostly assigning lights to clusters which grows faster than linearly (I think 1000 lights was about 1.5ms and 5000 was 7.5ms). I have seen papers and presentations leveraging compute shaders that can get this up to over 1 million. That said, I think any further optimisations should probably be done in a separate PR.
## Solution
- Add `RenderDevice` to the `Material` and `SpecializedMaterial` trait `::key()` functions to allow setting flags on the keys depending on feature/limit availability
- Make `GpuPointLights` and `ViewClusterBuffers` into enums containing `UniformVec` and `StorageBuffer` variants. Implement the necessary API on them to make usage the same for both cases, and the only difference is at initialisation time.
- Appropriate shader defs in the shader code to handle the two cases
## Context on some decisions / open questions
- I'm using `max_storage_buffers_per_shader_stage >= 3` as a check to see if storage buffers are supported. I was thinking about diving into 'binding resource management' but it feels like we don't have enough use cases to understand the problem yet, and it is mostly a separate concern to this PR, so I think it should be handled separately.
- Should `ViewClusterBuffers` and `ViewClusterBindings` be merged, duplicating the count variables into the enum variants?

# Objective
- Changing animation mid animation can leave the model not in its original position
- ~~The movement speed is fixed, no matter the size of the model~~
## Solution
- when changing animation, set it to its initial state and wait for one frame before changing the animation
- ~~when settings the camera controller, use the camera transform to know how far it is from the origin and use the distance for the speed~~
# Objective
The `bevy_app` crate has a lot of inconsistencies in the documentation (formatting, spelling, phrasing, consistency).
## Solution
Make it more consistent.
# Objective
- Fix#4416
- The scene has two root nodes, with the second one being the animation root
## Solution
- Check all scene root nodes, and add the `AnimationPlayer` component to nodes that are also animation roots
The scene viewer example doesn't run on wasm because it sets the asset folder to `std::env::var("CARGO_MANIFEST_DIR").unwrap()`, which isn't supported on the web.
Solution: set the asset folder to `"."` instead.
# Objective
Make `FromWorld` more useful for abstractions with a form similar to
```rs
trait FancyAbstraction {
type PreInitializedData: FromWorld;
}
```
## Solution
Add a `FromWorld` implementation for `SystemState` as well as a way to group together multiple `FromWorld` implementing types as one.
Note: I plan to follow up this PR with another to add `Local` support to exclusive systems, which should get a fair amount of use from the `FromWorld` implementation on `SystemState`.
# Objective
Avoid crashing if `RenderDevice` doesn't exist (required for headless mode).
Fixes#4392.
## Solution
Use `CompressedImageFormats::all()` if there is no `RenderDevice`.
# Objective
- Revert #4410
- `Input<T>.clear()` is the method call at the end of each frame for inputs. Clearing `pressed` in it mean that checking if a key is pressed will always return false
# Objective
- Fixes#1616, fixes#2225
- Let user specify an anchor for a sprite
## Solution
- Add an enum for an anchor point for most common values, with a variant for a custom point
- Defaults to Center to not change current behaviour
Co-authored-by: François <8672791+mockersf@users.noreply.github.com>
Fixes#3408#3001 also solves this but I dont see it getting merged any time soon so...
# Objective
make bevy ecs a lil bit less unsound
## Solution
make `EntityMut::get_component_mut` return borrows from self instead of `'w`
# Objective
- `Local`s can no longer be accessed outside of their creating system, but these docs say they can be.
- There's also little reason to have a pure wrapper type for `Local`s; they can just use the real type. The parameter name should be sufficiently documenting.
# Objective
- Animation is using `Name` to be able to address nodes in an entity free way
- When loading random animated gltf files, I noticed some had animations without names sometimes
## Solution
- Add default names to all nodes
