# Objective
In this PR I added the ability to opt-out graphical backends. Closes#3155.
## Solution
I turned backends into `Option` ~~and removed panicking sub app API to force users handle the error (was suggested by `@cart`)~~.
# Objective
The current 2d rendering is specialized to render sprites, we need a generic way to render 2d items, using meshes and materials like we have for 3d.
## Solution
I cloned a good part of `bevy_pbr` into `bevy_sprite/src/mesh2d`, removed lighting and pbr itself, adapted it to 2d rendering, added a `ColorMaterial`, and modified the sprite rendering to break batches around 2d meshes.
~~The PR is a bit crude; I tried to change as little as I could in both the parts copied from 3d and the current sprite rendering to make reviewing easier. In the future, I expect we could make the sprite rendering a normal 2d material, cleanly integrated with the rest.~~ _edit: see <https://github.com/bevyengine/bevy/pull/3460#issuecomment-1003605194>_
## Remaining work
- ~~don't require mesh normals~~ _out of scope_
- ~~add an example~~ _done_
- support 2d meshes & materials in the UI?
- bikeshed names (I didn't think hard about naming, please check if it's fine)
## Remaining questions
- ~~should we add a depth buffer to 2d now that there are 2d meshes?~~ _let's revisit that when we have an opaque render phase_
- ~~should we add MSAA support to the sprites, or remove it from the 2d meshes?~~ _I added MSAA to sprites since it's really needed for 2d meshes_
- ~~how to customize vertex attributes?~~ _#3120_

# Objective
- Allow the user to specify the priority when configuring wgpu features/limits and by default use the maximum capabilities of the chosen adapter.
## Solution
- Add a `WgpuOptionsPriority` enum with `Compatibility`, `Functionality` and `WebGL2` options.
- Add a `priority: WgpuOptionsPriority` member to `WgpuOptions`.
- When initialising the renderer, if `WgpuOptions::priority == WgpuOptionsPriority::Functionality`, query the adapter for the available features and limits, use them when creating a device, and update `WgpuOptions` with those values. If `Compatibility` use the behaviour as before this PR. If `WebGL2` then use the WebGL2 downlevel limits as used when when building for wasm, for convenience of testing WebGL2 limits without having to build for wasm.
- Add an environment variable `WGPU_OPTIONS_PRIO` that takes `compatibility`, `functionality`, `webgl2`.
- Default to `WgpuOptionsPriority::Functionality`.
- Insert updated `WgpuOptions` into render app world as well. This is useful for applying the limits when rendering, such as limiting the directional light shadow map texture to 2048x2048 when using WebGL2 downlevel limits but not on wasm.
- Reduced `draw_state` logs from `debug` to `trace` and added `debug` level logs for the wgpu features and limits. Use `RUST_LOG=bevy_render=debug` to see the output.
# Objective
- Add support for loading lights from glTF 2.0 files
## Solution
- This adds support for the KHR_punctual_lights extension which supports point, directional, and spot lights, though we don't yet support spot lights.
- Inserting light bundles when creating scenes required registering some more light bundle component types.
This PR is part of the issue #3492.
# Objective
- Clean up dead code in `bevy_core`.
- Add and update the `bevy_core` documentation to achieve a 100% documentation coverage.
- Add the #![warn(missing_docs)] lint to keep the documentation coverage for the future.
# Solution
- Remove unused `Bytes`, `FromBytes`, `Labels`, and `EntityLabels` types and associated systems.
- Made several types private that really only have use as internal types, mostly pertaining to fixed timestep execution.
- Add and update the bevy_core documentation.
- Add the #![warn(missing_docs)] lint.
# Open Questions
Should more of the internal states of `FixedTimestep` be public? Seems mostly to be an implementation detail unless someone really needs that fixed timestep state.
# Objective
Docs updates.
## Solution
- Detail what `OrthographicCameraBundle::new_2d()` creates.
- Fix a few renamed parameters in comments of `TrackedRenderPass`.
- Add missing comments for viewport and debug markers.

# Objective
- `Msaa` was disabled in webgl due to a bug in wgpu
- Bug has been fixed (https://github.com/gfx-rs/wgpu/pull/2307) and backported (https://github.com/gfx-rs/wgpu/pull/2327), and updates for [`wgpu-core`](https://crates.io/crates/wgpu-core/0.12.1) and [`wgpu-hal`](https://crates.io/crates/wgpu-hal/0.12.1) have been released
## Solution
- Remove custom config for `Msaa` in webgl
- I also changed two options that were using the arch instead of the `webgl` feature. it shouldn't change much for webgl, but could help if someone wants to target wasm but not webgl2

Dynamic types (`DynamicStruct`, `DynamicTupleStruct`, `DynamicTuple`, `DynamicList` and `DynamicMap`) are used when deserializing scenes, but currently they can only be applied to existing concrete types. This leads to issues when trying to spawn non trivial deserialized scene.
For components, the issue is avoided by requiring that reflected components implement ~~`FromResources`~~ `FromWorld` (or `Default`). When spawning, a new concrete type is created that way, and the dynamic type is applied to it. Unfortunately, some components don't have any valid implementation of these traits.
In addition, any `Vec` or `HashMap` inside a component will panic when a dynamic type is pushed into it (for instance, `Text` panics when adding a text section).
To solve this issue, this PR adds the `FromReflect` trait that creates a concrete type from a dynamic type that represent it, derives the trait alongside the `Reflect` trait, drops the ~~`FromResources`~~ `FromWorld` requirement on reflected components, ~~and enables reflection for UI and Text bundles~~. It also adds the requirement that fields ignored with `#[reflect(ignore)]` implement `Default`, since we need to initialize them somehow.

# Objective
- I want to port `bevy_egui` to Bevy main and only reuse re-exports from Bevy
## Solution
- Add exports for `BufferBinding` and `BufferDescriptor`
Co-authored-by: François <8672791+mockersf@users.noreply.github.com>
# Objective
Fixes#3422
## Solution
Adds the existing `Visibility` component to UI bundles and checks for it in the extract phase of the render app.
The `ComputedVisibility` component was not added. I don't think the UI camera needs frustum culling, but having `RenderLayers` work may be desirable. However I think we would need to change `check_visibility()` to differentiate between 2d, 3d and UI entities.
# Objective
- Our crevice is still called "crevice", which we can't use for a release
- Users would need to use our "crevice" directly to be able to use the derive macro
## Solution
- Rename crevice to bevy_crevice, and crevice-derive to bevy-crevice-derive
- Re-export it from bevy_render, and use it from bevy_render everywhere
- Fix derive macro to work either from bevy_render, from bevy_crevice, or from bevy
## Remaining
- It is currently re-exported as `bevy::render::bevy_crevice`, is it the path we want?
- After a brief suggestion to Cart, I changed the version to follow Bevy version instead of crevice, do we want that?
- Crevice README.md need to be updated
- in the `Cargo.toml`, there are a few things to change. How do we want to change them? How do we keep attributions to original Crevice?

# Objective
Instead of panicking when the `indices` field of a mesh is `None`, actually manage it.
This is just a question of keeping track of the vertex buffer size.
## Notes
* Relying on this change to improve performance on [bevy_debug_lines using the new renderer](https://github.com/Toqozz/bevy_debug_lines/pull/10)
* I'm still new to rendering, my only expertise with wgpu is the learn-wgpu tutorial, likely I'm overlooking something.
### Problem
- shader processing errors are not displayed
- during hot reloading when encountering a shader with errors, the whole app crashes
### Solution
- log `error!`s for shader processing errors
- when `cfg(debug_assertions)` is enabled (i.e. you're running in `debug` mode), parse shaders before passing them to wgpu. This lets us handle errors early.
# Objective
- 3d examples fail to run in webgl2 because of unsupported texture formats or texture too large
## Solution
- switch to supported formats if a feature is enabled. I choose a feature instead of a build target to not conflict with a potential webgpu support
Very inspired by 6813b2edc5, and need #3290 to work.
I named the feature `webgl2`, but it's only needed if one want to use PBR in webgl2. Examples using only 2D already work.

# Objective
Add missing methods to `TrackedRenderPass`
- `set_push_constants`
- `set_viewport`
- `insert_debug_marker`
- `push_debug_group`
- `pop_debug_group`
- `set_blend_constant`
https://docs.rs/wgpu/0.12.0/wgpu/struct.RenderPass.html
I need `set_push_constants` but started adding the others as I noticed they were also missing. The `draw indirect` family of methods are still missing as are the `timestamp query` methods.
# Objective
- Only bevy_render should depend directly on wgpu
- This helps to make sure bevy_render re-exports everything needed from wgpu
## Solution
- Remove bevy_pbr, bevy_sprite and bevy_ui dependency on wgpu
Co-authored-by: François <8672791+mockersf@users.noreply.github.com>
# Objective
Fixes#3352Fixes#3208
## Solution
- Update wgpu to 0.12
- Update naga to 0.8
- Resolve compilation errors
- Remove [[block]] from WGSL shaders (because it is depracated and now wgpu cant parse it)
- Replace `elseif` with `else if` in pbr.wgsl
# Objective
- The multiple windows example which was viciously murdered in #3175.
- cart asked me to
## Solution
- Rework the example to work on pipelined-rendering, based on the work from #2898
# Objective
- There are a few warnings when building Bevy docs for dead links
- CI seems to not catch those warnings when it should
## Solution
- Enable doc CI on all Bevy workspace
- Fix warnings
- Also noticed plugin GilrsPlugin was not added anymore when feature was enabled
First commit to check that CI would actually fail with it: https://github.com/bevyengine/bevy/runs/4532652688?check_suite_focus=true

# Objective And Solution
Add `set_scissor_rect` from wgpu-rs to the `TrackedRenderPass`. wgpu documentation can be found here:
https://docs.rs/wgpu/latest/wgpu/struct.RenderPass.html#method.set_scissor_rect
The reason for adding this is to cull fragments that are outside of the given rect. For my purposes this is extremely useful for UI.
This makes the [New Bevy Renderer](#2535) the default (and only) renderer. The new renderer isn't _quite_ ready for the final release yet, but I want as many people as possible to start testing it so we can identify bugs and address feedback prior to release.
The examples are all ported over and operational with a few exceptions:
* I removed a good portion of the examples in the `shader` folder. We still have some work to do in order to make these examples possible / ergonomic / worthwhile: #3120 and "high level shader material plugins" are the big ones. This is a temporary measure.
* Temporarily removed the multiple_windows example: doing this properly in the new renderer will require the upcoming "render targets" changes. Same goes for the render_to_texture example.
* Removed z_sort_debug: entity visibility sort info is no longer available in app logic. we could do this on the "render app" side, but i dont consider it a priority.
# Objective
- Checks for NaN in computed NDC space coordinates, fixing unexpected NaN in a fallible (`Option<T>`) function.
## Solution
- Adds a NaN check, in addition to the existing NDC bounds checks.
- This is a helper function, and should have no performance impact to the engine itself.
- This will help prevent hard-to-trace NaN propagation in user code, by returning `None` instead of `Some(NaN)`.
Depends on https://github.com/bevyengine/bevy/pull/3269 for CI error fix.
# Objective
Fixes recent pipeline errors:
```

```
## Solution
- Replaced `IntoIter::new` with `IntoIterator::into_iter`
## Suggestions
For me it looks like two equivalent `Mesh` structs with the same methods. Should we refactor it? Or, they will be different in the near future?

# Objective
- New clippy lints with rust 1.57 are failing
## Solution
- Fixed clippy lints following suggestions
- I ignored clippy in old renderer because there was many and it will be removed soon
# Objective
- Update vendor crevice to have the latest update from crevice 0.8.0
- Using https://github.com/ElectronicRU/crevice/tree/arrays which has the changes to make arrays work
## Solution
- Also updated glam and hexasphere to only have one version of glam
- From the original PR, using crevice to write GLSL code containing arrays would probably not work but it's not something used by Bevy
Objective
During work on #3009 I've found that not all jobs use actions-rs, and therefore, an previous version of Rust is used for them. So while compilation and other stuff can pass, checking markup and Android build may fail with compilation errors.
Solution
This PR adds `action-rs` for any job running cargo, and updates the edition to 2021.
# Objective
The current TODO comment is out of date

# Objective
The update to wgpu 0.11 broke CI for android. This was due to a confusion between `bevy::render::ShaderStage` and `wgpu::ShaderStage`.
## Solution
Revert the incorrect change
Upgrades both the old and new renderer to wgpu 0.11 (and naga 0.7). This builds on @zicklag's work here #2556.

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

This updates the `pipelined-rendering` branch to use the latest `bevy_ecs` from `main`. This accomplishes a couple of goals:
1. prepares for upcoming `custom-shaders` branch changes, which were what drove many of the recent bevy_ecs changes on `main`
2. prepares for the soon-to-happen merge of `pipelined-rendering` into `main`. By including bevy_ecs changes now, we make that merge simpler / easier to review.
I split this up into 3 commits:
1. **add upstream bevy_ecs**: please don't bother reviewing this content. it has already received thorough review on `main` and is a literal copy/paste of the relevant folders (the old folders were deleted so the directories are literally exactly the same as `main`).
2. **support manual buffer application in stages**: this is used to enable the Extract step. we've already reviewed this once on the `pipelined-rendering` branch, but its worth looking at one more time in the new context of (1).
3. **support manual archetype updates in QueryState**: same situation as (2).
# Objective
- Make it easy to use HexColorError with `thiserror`, i.e. converting it into other error types.
Makes this possible:
```rust
#[derive(Debug, thiserror::Error)]
pub enum LdtkError {
#[error("An error occured while deserializing")]
Json(#[from] serde_json::Error),
#[error("An error occured while parsing a color")]
HexColor(#[from] bevy::render::color::HexColorError),
}
```
## Solution
- Derive thiserror::Error the same way we do elsewhere (see query.rs for instance)
# Objective
Enable using exact World lifetimes during read-only access . This is motivated by the new renderer's need to allow read-only world-only queries to outlive the query itself (but still be constrained by the world lifetime).
For example:
115b170d1f/pipelined/bevy_pbr2/src/render/mod.rs (L774)
## Solution
Split out SystemParam state and world lifetimes and pipe those lifetimes up to read-only Query ops (and add into_inner for Res). According to every safety test I've run so far (except one), this is safe (see the temporary safety test commit). Note that changing the mutable variants to the new lifetimes would allow aliased mutable pointers (try doing that to see how it affects the temporary safety tests).
The new state lifetime on SystemParam does make `#[derive(SystemParam)]` more cumbersome (the current impl requires PhantomData if you don't use both lifetimes). We can make this better by detecting whether or not a lifetime is used in the derive and adjusting accordingly, but that should probably be done in its own pr.
## Why is this a draft?
The new lifetimes break QuerySet safety in one very specific case (see the query_set system in system_safety_test). We need to solve this before we can use the lifetimes given.
This is due to the fact that QuerySet is just a wrapper over Query, which now relies on world lifetimes instead of `&self` lifetimes to prevent aliasing (but in systems, each Query has its own implied lifetime, not a centralized world lifetime). I believe the fix is to rewrite QuerySet to have its own World lifetime (and own the internal reference). This will complicate the impl a bit, but I think it is doable. I'm curious if anyone else has better ideas.
Personally, I think these new lifetimes need to happen. We've gotta have a way to directly tie read-only World queries to the World lifetime. The new renderer is the first place this has come up, but I doubt it will be the last. Worst case scenario we can come up with a second `WorldLifetimeQuery<Q, F = ()>` parameter to enable these read-only scenarios, but I'd rather not add another type to the type zoo.
# Objective
- 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)
```
