# Objective
- Allow the user to set the clear color when using the pipelined renderer
## Solution
- Add a `ClearColor` resource that can be added to the world to configure the clear color
## Remaining Issues
Currently the `ClearColor` resource is cloned from the app world to the render world every frame. There are two ways I can think of around this:
1. Figure out why `app_world.is_resource_changed::<ClearColor>()` always returns `true` in the `extract` step and fix it so that we are only updating the resource when it changes
2. Require the users to add the `ClearColor` resource to the render sub-app instead of the parent app. This is currently sub-optimal until we have labled sub-apps, and probably a helper funciton on `App` such as `app.with_sub_app(RenderApp, |app| { ... })`. Even if we had that, I think it would be more than we want the user to have to think about. They shouldn't have to know about the render sub-app I don't think.
I think the first option is the best, but I could really use some help figuring out the nuance of why `is_resource_changed` is always returning true in that context.
# Objective
- the plugin guidelines should be up-to-date and easy to read/understand
## Solution
* point to "Bevy Assets" instead of old "Awesome Bevy"
* restructure sections
* same order for sections and checklist
* Update examples with newest release/rev
Updates the requirements on [glam](https://github.com/bitshifter/glam-rs) to permit the latest version.

# Objective
- We currently depends on ndk 0.2, 0.3, 0.4
- Only 0.2 dependencies comes from Bevy itself
## Solution
- Replace #1371
- Update Bevy to ndk-glue 0.4
- Also fixes duplicate dependency CI issue
# Objective
While implementing a plugin for my rollback networking library, I needed to load/save parts of the world. For this, I made a WorldSnapshot that works quite like the current DynamicScene. Using a TypeRegistry to register component types I want to save/load and then using ReflectComponents methods to add or apply components of the given types.
However, I noticed there is no method to remove components from entities through the ReflectComponent.
## Solution
I added a `remove_component` field to the `ReflectComponent` struct, as well as a `pub fn remove_component(&self, world: &mut World, entity: Entity)` to call that function in `remove_component`. This follows exactly the same pattern all other methods/fields in this struct look like.
This is an example how it could be used (at least how I would use it):
6c003f86f1/src/world_snapshot.rs (L133)
# Objective
Enable using exact World lifetimes during read-only access . This is motivated by the new renderer's need to allow read-only world-only queries to outlive the query itself (but still be constrained by the world lifetime).
For example:
115b170d1f/pipelined/bevy_pbr2/src/render/mod.rs (L774)
## Solution
Split out SystemParam state and world lifetimes and pipe those lifetimes up to read-only Query ops (and add into_inner for Res). According to every safety test I've run so far (except one), this is safe (see the temporary safety test commit). Note that changing the mutable variants to the new lifetimes would allow aliased mutable pointers (try doing that to see how it affects the temporary safety tests).
The new state lifetime on SystemParam does make `#[derive(SystemParam)]` more cumbersome (the current impl requires PhantomData if you don't use both lifetimes). We can make this better by detecting whether or not a lifetime is used in the derive and adjusting accordingly, but that should probably be done in its own pr.
## Why is this a draft?
The new lifetimes break QuerySet safety in one very specific case (see the query_set system in system_safety_test). We need to solve this before we can use the lifetimes given.
This is due to the fact that QuerySet is just a wrapper over Query, which now relies on world lifetimes instead of `&self` lifetimes to prevent aliasing (but in systems, each Query has its own implied lifetime, not a centralized world lifetime). I believe the fix is to rewrite QuerySet to have its own World lifetime (and own the internal reference). This will complicate the impl a bit, but I think it is doable. I'm curious if anyone else has better ideas.
Personally, I think these new lifetimes need to happen. We've gotta have a way to directly tie read-only World queries to the World lifetime. The new renderer is the first place this has come up, but I doubt it will be the last. Worst case scenario we can come up with a second `WorldLifetimeQuery<Q, F = ()>` parameter to enable these read-only scenarios, but I'd rather not add another type to the type zoo.
[**RENDERED**](https://github.com/alice-i-cecile/bevy/blob/better-contributing/CONTRIBUTING.md)
Improves #910. As discussed in #1309, we'll need to synchronize content between this and the Bevy website in some way (and clean up the .github file perhaps?).
I think doing it as a root-directory file is nicer for discovery, but that's a conversation I'm interested in having.
This document is intended to be helpful to beginners to open source and Bevy, and captures what I've learned about our informal practices and values.
Reviewers: I'm particularly interested in:
- opinions on the items **What we're trying to build**, where I discuss some of the project's high-level values and goals
- more relevant details on the `bevy` subcrates for **Getting oriented**
- useful tricks and best practices that I missed
- better guidance on how to contribute to the Bevy book from @cart <3
# Objective
This:
```rust
use bevy::prelude::*;
fn main() {
App::new()
.add_system(test)
.run();
}
fn test(entities: Query<Entity>) {
let mut combinations = entities.iter_combinations_mut();
while let Some([e1, e2]) = combinations.fetch_next() {
dbg!(e1);
}
}
```
fails with the message "the trait bound `bevy::ecs::query::EntityFetch: std::clone::Clone` is not satisfied".
## Solution
It works after adding the naive clone implementation to EntityFetch. I'm not super familiar with ECS internals, so I'd appreciate input on this.
## Objective
- Clean up remaining references to the trait `FromResources`, which was replaced in favor of `FromWorld` during the ECS rework.
## Solution
- Remove the derive macro for `FromResources`
- Change doc references of `FromResources` to `FromWorld`
(this is the first item in #2576)
# Objective
- Provides more useful error messages when using unsupported shader features.
## Solution Fixes#869
- Provided a error message as follows (adding name, set and binding):
```
Unsupported shader bind type CombinedImageSampler (name noiseVol0, set 0, binding 9)
```
# Objective
Fix ComputePipelineDescriptor missing from WGPU exports
## Solution
Added it to the pub use wgpu::{ ... }

I didn't know about MinimalPlugins for way too long. This should increase visibility for others.
# Objective
Improve visibility and discover in the docs for Default and Minimal Plugins.
## Solution
Links the two Docs pages.

# Objective
- Allow `ScheduleRunnerPlugin` to be instantiated without curly braces. Other plugins in the library already use the semicolon syntax.
- Currently, you have to do the following:
```rust
App::build()
.add_plugin(bevy::core::CorePlugin)
.add_plugin(bevy::app::ScheduleRunnerPlugin {})
```
- With the proposed change you can do this:
```rust
App::build()
.add_plugin(bevy::core::CorePlugin)
.add_plugin(bevy::app::ScheduleRunnerPlugin)
```
## Solution
- Change the `ScheduleRunnerPlugin` definition to use a semicolon instead of curly braces.
# Objective
- Prevent the need to specify a sprite size when using the pipelined sprite renderer
## Solution
- Re-introduce the sprite auto resize system from the old renderer
# Objective
- Allow you to compile Bevy with the `bevy_sprite2` feature, but without the `bevy_pbr2` feature.
- This currently fails because the `bevy_sprite2` crate does not require the `derive` feature of the `bytemuck` crate in its `Cargo.toml`, even though it is required to compile.
## Solution
- Add the `derive` feature of `bytemuck` to the `bevy_sprite2` crate
## Objective
This code would result in a crash:
```rust
use bevy::prelude::*;
fn main() {
let mut world = World::new();
let child = world.spawn().id();
world.spawn().push_children(&[child]);
}
```
## Solution
Update the `EntityMut`'s location after inserting a component on the children entities, as it may have changed.
# Objective
This fixes not having access to StorageTextureAccess in the API, which is needed for using storage textures
## Solution
Added it to the use in render_resource module
Co-authored-by: Dimas <skythedragon@outlook.com>
# Objective
- #2551 revamped our CI setup which included running clippy and rustfmt in another Job.
- This new Job wasn't added to the bors.toml, which means that PRs would be accepted that didn't run them.
## Solution
- Add the "ci" job to the bors.toml
# Objective
Restore the functionality of sprite atlases in the new renderer.
### **Note:** This PR relies on #2555
## Solution
Mostly just a copy paste of the existing sprite atlas implementation, however I unified the rendering between sprites and atlases.

It doesn't compile on wasm, and it's full of footguns
# Objective
- If bevy is used with default features on wasm, there's more of a chance it will compile
- Note that I haven't done a full audit - it's possible that there are other problematic crates
## Solution
- `bevy_dynamic_plugin` is no longer a default plugin
- I've also done an accidental drive by reformatting of the root `Cargo.toml`, as I have [Even Better Toml](https://github.com/tamasfe/taplo) installed.
- (Please, rustfmt do this for us)
# Objective
Port bevy_gltf to the pipelined-rendering branch.
## Solution
crates/bevy_gltf has been copied and pasted into pipelined/bevy_gltf2 and modifications were made to work with the pipelined-rendering branch. Notably vertex tangents and vertex colours are not supported.

# Objective
notify 5.0.0-pre.11 breaks the interface again, but apparently in a way that's similar to how it used to be
## Solution
Bump `bevy_asset` dependency on notify to `5.0.0-pre.11` and fix the errors that crop up.
It looks like `pre.11` was mentioned in #2528 by @mockersf but there's no mention of why `pre.10` was chosen ultimately.
This decouples the opinionated "core pipeline" from the new (less opinionated) bevy_render crate. The "core pipeline" is intended to be used by crates like bevy_sprites, bevy_pbr, bevy_ui, and 3rd party crates that extends core rendering functionality.
# Objective
There is currently a 1-to-1 mapping between components and real rust types. This means that it is impossible for multiple components to be represented by the same rust type or for a component to not have a rust type at all. This means that component types can't be defined in languages other than rust like necessary for scripting or sandboxed (wasm?) plugins.
## Solution
Refactor `ComponentDescriptor` and `Bundle` to remove `TypeInfo`. `Bundle` now uses `ComponentId` instead. `ComponentDescriptor` is now always created from a rust type instead of through the `TypeInfo` indirection. A future PR may make it possible to construct a `ComponentDescriptor` from it's fields without a rust type being involved.
Makes the "Render App World" directly available to Extract step systems as a `RenderWorld` resource. Prior to this, there was no way to directly read / write render world state during the Extract step. The only way to make changes was through Commands (which were applied at the end of the stage).
```rust
// `thing` is an "app world resource".
fn extract_thing(thing: Res<Thing>, mut render_world: ResMut<RenderWorld>) {
render_world.insert_resource(ExtractedThing::from(thing));
}
```
RenderWorld makes a number of scenarios possible:
* When an extract system does big allocations, it is now possible to reuse them across frames by retrieving old values from RenderWorld (at the cost of reduced parallelism from unique RenderWorld borrows).
* Enables inserting into the same resource across multiple extract systems
* Enables using past RenderWorld state to inform future extract state (this should generally be avoided)
Ultimately this is just a subset of the functionality we want. In the future, it would be great to have "multi-world schedules" to enable fine grained parallelism on the render world during the extract step. But that is a research project that almost certainly won't make it into 0.6. This is a good interim solution that should easily port over to multi-world schedules if/when they land.
# Objective
- Remove all the `.system()` possible.
- Check for remaining missing cases.
## Solution
- Remove all `.system()`, fix compile errors
- 32 calls to `.system()` remains, mostly internals, the few others should be removed after #2446
# Objective
While looking at the code of `World`, I noticed two basic functions (`get` and `get_mut`) that are probably called a lot and with simple code that are not `inline`
## Solution
- Add benchmark to check impact
- Add `#[inline]`
```

This is extracted out of eb8f973646476b4a4926ba644a77e2b3a5772159 and includes some additional changes to remove all references to AppBuilder and fix examples that still used App::build() instead of App::new(). In addition I didn't extract the sub app feature as it isn't ready yet.

This logic was in both `remove_bundle` and ` remove_bundle_intersection` but only differed by whether we call `.._forget_missing_..` or `.._drop_missing_..`
# Objective
- There are a few random failures in CI, mostly due to contacting crates.io or checking for deadlinks
- CI can take some time, more than 20 minutes for a full status
- A clippy/format issue stops running tests on other platforms
## Solution
- Use GitHub cache for cargo artefacts
- This speeds up builds and reduce dependencies on outside world
- Reorder and add dependencies between short jobs. They are still setup to run even if one of the dependency failed
- This reduce the number of parallel jobs that are running for one PR. On GitHub free tier, we're limited to 20.
- Split CI checks (format & clippy) in its own job
- This speeds up test jobs, and allow us to not kill all platform tests for a format issue
- Retry in case of dead links check failure
- Internet is just that kind of place where things may seem dead at some point but back alive 5 seconds later

# Objective
- Related to #2514 - not sure if it's a proper fix long term
- CI was complaining Error: Path `"/usr/local/lib/android/sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android31-clang"` was not found
- A lot of questions started popping up 10 days ago about ["android build tools 31 corrupted"](https://www.google.com/search?q=android+build+tools+31+corrupted)
- https://stackoverflow.com/questions/68387270/android-studio-error-installed-build-tools-revision-31-0-0-is-corrupted
- Uninstalling `"build-tools;31.0.0"` doesn't seem to work, as it removes other components even though `"build-tools;30.0.3"` are available
## Solution
- Uninstalling `"platforms;android-31"` seems to do the trick and `cargo-apk` stops trying to target `...31`
Android is not my thing, this solution was found with a lot of trials and errors. I am not sure how long term it is, I don't know the release schedule of android build tools, or if we need to target this 31 thing. I just wanted to stop all those failed ci everywhere...
* 3d_scene_pipelined: Use a shallower directional light angle to provoke acne
* cornell_box_pipelined: Remove bias tweaks
* bevy_pbr2: Simplify shadow biases by moving them to linear depth
* bevy_pbr2: Do not use DepthBiasState
* bevy_pbr2: Do not use bilinear filtering for sampling depth textures
* pbr.wgsl: Remove unnecessary comment
* bevy_pbr2: Do manual shadow map depth comparisons for more flexibility
* examples: Add shadow_biases_pipelined example
This is useful for stress testing biases.
* bevy_pbr2: Scale the point light normal bias by the shadow map texel size
This allows the normal bias to be small close to the light source where the
shadow map texel to screen texel ratio is high, but is appropriately large
further away from the light source where the shadow map texel can easily cover
multiple screen texels.
* shadow_biases_pipelined: Add support for toggling directional / point light
* shadow_biases_pipelined: Cleanup
* bevy_pbr2: Scale the directional light normal bias by the shadow map texel size
* shadow_biases_pipelined: Fit the orthographic projection around the scene
* bevy_pbr2: Directional lights should have no shadows outside their projection
Before this change, sampling a fragment position from outside the ndc volume
would result in the return sample being clamped to the edge in x,y or possibly
always casting a shadow for fragment positions past the orthographic
projection's far plane.
* bevy_pbr2: Fix the default directional light normal bias
* Revert "bevy_pbr2: Do manual shadow map depth comparisons for more flexibility"
This reverts commit 7df1bab38a42d8a33bc50ca583d4be37bd9c9f0d.
* shadow_biases_pipelined: Adjust directional light normal bias in 0.1 increments
* pbr.wgsl: Add a couple of clarifying comments
* Revert "bevy_pbr2: Do not use bilinear filtering for sampling depth textures"
