# Objective
Reduce compilation time
# Solution
Remove unused dependencies. While this PR doesn't remove any crates from `Cargo.lock`, it may unlock more build parallelism.
# Objective
Fixes how the layer bit is unset in the RenderLayers bit mask when calling the `without` method.
## Solution
Unsets the layer bit using `&=` and the inverse of the layer bit mask.
# Objective
- CI jobs are starting to fail due to `clippy::bool-assert-comparison` and `clippy::single_component_path_imports` being triggered.
## Solution
- Fix all uses where `asset_eq!(<condition>, <bool>)` could be replace by `assert!`
- Move the `#[allow()]` for `single_component_path_imports` to `#![allow()]` at the start of the files.
fixes#2169
Instead of having custom methods with reduced visibility, implement `From<image::DynamicImage> for Texture` and `TryFrom<Texture> for image::DynamicImage`
Since `visible_entities_system` already checks `Visiblie::is_visible` for each entity and requires it to be `true`, there's no reason to verify visibility in `PassNode::prepare` which consumes entities produced by the system.
When implementing `AssetLoader ` you need to specify which File extensions are supported by that loader.
Currently, Bevy always says it supports extensions that actually require activating a Feature beforehand.
This PR adds cf attributes, so Bevy only tries to load those Extensions whose Features were activated.
This prevents Bevy from Panicking and reports such a warning:
```
Jun 02 23:05:57.139 WARN bevy_asset::asset_server: no `AssetLoader` found for the following extension: ogg
```
This also fixes the Bug, that the `png Feature had to be activated even if you wanted to load a different image format.
Fixes#640
`ResMut`, `Mut` and `ReflectMut` all share very similar code for change detection.
This PR is a first pass at refactoring these implementation and removing a lot of the duplicated code.
Note, this introduces a new trait `ChangeDetectable`.
Please feel free to comment away and let me know what you think!
This gets rid of multiple unsafe blocks that we had to maintain ourselves, and instead depends on library that's commonly used and supported by the ecosystem. We also get support for glam types for free.
There is still some things to clear up with the `Bytes` trait, but that is a bit more substantial change and can be done separately. Also there are already separate efforts to use `crevice` crate, so I've just added that as a TODO.
There's what might be considered a proper bug in `PipelineCompiler::compile_pipeline()`, where it overwrites the `step_mode` for the passed in `VertexBufferLayout` with `InputStepMode::Vertex`. Due to this some ugly workarounds are needed to do any kind of instancing.
In the somewhat longer term, `PipelineCompiler::compile_pipeline()` should probably also handle a `Vec<VertexBufferLayout>`, but that would be a (slightly) larger PR, rather than a bugfix. And I'd love to have this fix in sooner than we can deal with a bigger PR.

Required by #1429,
- Adds the `Ushort4` vertex attribute for joint indices
- `Mesh::ATTRIBUTE_JOINT_WEIGHT` and `Mesh::ATTRIBUTE_JOINT_INDEX` to import vertex attributes related to skinning from GLTF
- impl `Default` for `Mesh` a empty triangle mesh is created (needed by reflect)
- impl `Reflect` for `Mesh` all attributes are ignored (needed by the animation system)
Changes to get Bevy to compile with wgpu master.
With this, on a Mac:
* 2d examples look fine
* ~~3d examples crash with an error specific to metal about a compilation error~~
* 3d examples work fine after enabling feature `wgpu/cross`
Feature `wgpu/cross` seems to be needed only on some platforms, not sure how to know which. It was introduced in https://github.com/gfx-rs/wgpu-rs/pull/826
Fixes#2037 (and then some)
Problem:
- `TypeUuid`, `RenderResource`, and `Bytes` derive macros did not properly handle generic structs.
Solution:
- Rework the derive macro implementations to handle the generics.
If a mesh without any vertex attributes is rendered (for example, one that only has indices), bevy will crash since the mesh still creates a vertex buffer even though it's empty. Later code assumes that there is vertex data, causing an index-out-of-bounds panic. This PR fixes the issue by adding a check that there is any vertex data before creating a vertex buffer.
I ran into this issue while rendering a tilemap without any vertex attributes (only indices).

There are cases where we want an enum variant name. Right now the only way to do that with rust's std is to derive Debug, but this will also print out the variant's fields. This creates the unfortunate situation where we need to manually write out each variant's string name (ex: in #1963), which is both boilerplate-ey and error-prone. Crates such as `strum` exist for this reason, but it includes a lot of code and complexity that we don't need.
This adds a dead-simple `EnumVariantMeta` derive that exposes `enum_variant_index` and `enum_variant_name` functions. This allows us to make cases like #1963 much cleaner (see the second commit). We might also be able to reuse this logic for `bevy_reflect` enum derives.
In bevy_webgl2, the `RenderResourceContext` is created after startup as it needs to first wait for an event from js side:
f31e5d49de/src/lib.rs (L117)
remove `panic` introduced in #1965 and log as a `warn` instead
This implementations allows you
convert std::vec::Vec<T> to VertexAttributeValues::T and back.
# Examples
```rust
use std::convert::TryInto;
use bevy_render::mesh::VertexAttributeValues;
// creating vector of values
let before = vec![[0_u32; 4]; 10];
let values = VertexAttributeValues::from(before.clone());
let after: Vec<[u32; 4]> = values.try_into().unwrap();
assert_eq!(before, after);
```

Allows render resources to move data to the heap by boxing them. I did this as a workaround to #1892, but it seems like it'd be useful regardless. If not, feel free to close this PR.
Implements `Byteable` and `RenderResource` for any array containing `Byteable` elements. This allows `RenderResources` to be implemented on structs with arbitrarily-sized arrays, among other things:
```rust
#[derive(RenderResources, TypeUuid)]
#[uuid = "2733ff34-8f95-459f-bf04-3274e686ac5f"]
struct Foo {
buffer: [i32; 256],
}
```
Fixes#1809. It makes it also possible to use `derive` for `SystemParam` inside ECS and avoid manual implementation. An alternative solution to macro changes is to use `use crate as bevy_ecs;` in `event.rs`.
The `VertexBufferLayout` returned by `crates\bevy_render\src\mesh\mesh.rs:308` was unstable, because `HashMap.iter()` has a random order. This caused the pipeline_compiler to wrongly consider a specialization to be different (`crates\bevy_render\src\pipeline\pipeline_compiler.rs:123`), causing each mesh changed event to potentially result in a different `PipelineSpecialization`. This in turn caused `Draw` to emit a `set_pipeline` much more often than needed.
This fix shaves off a `BindPipeline` and two `BindDescriptorSets` (for the Camera and for global renderresources) for every mesh after the first that can now use the same specialization, where it didn't before (which was random).
`StableHashMap` was not a good replacement, because it isn't `Clone`, so instead I replaced it with a `BTreeMap` which is OK in this instance, because there shouldn't be many insertions on `Mesh.attributes` after the mesh is created.

These changes are a bit unrelated. I can open separate PRs if someone wants that.
After #1697 I looked at all other Iterators from Bevy and added overrides for `size_hint` where it wasn't done.
Also implemented `ExactSizeIterator` where applicable.
In shaders, `vec3` should be avoided for `std140` layout, as they take the size of a `vec4` and won't support manual padding by adding an additional `float`.
This change is needed for 3D to work in WebGL2. With it, I get PBR to render

Without it, nothing renders... @cart Could this be considered for 0.5 release?
Also, I learned shaders 2 days ago, so don't hesitate to correct any issue or misunderstanding I may have
bevy_webgl2 PR in progress for Bevy 0.5 is here if you want to test: https://github.com/rparrett/bevy_webgl2/pull/1
I think [collection, thing_removed_from_collection] is a more natural order than [thing_removed_from_collection, collection]. Just a small tweak that I think we should include in 0.5.
This PR adds normal maps on top of PBR #1554. Once that PR lands, the changes should look simpler.
Edit: Turned out to be so little extra work, I added metallic/roughness texture too. And occlusion and emissive.

This PR adds two systems to the sprite module that culls Sprites and AtlasSprites that are not within the camera's view.
This is achieved by removing / adding a new `Viewable` Component dynamically.
Some of the render queries now use a `With<Viewable>` filter to only process the sprites that are actually on screen, which improves performance drastically for scene swith a large amount of sprites off-screen.
https://streamable.com/vvzh2u
This scene shows a map with a 320x320 tiles, with a grid size of 64p.
This is exactly 102400 Sprites in the entire scene.
Without this PR, this scene runs with 1 to 4 FPS.
With this PR..
.. at 720p, there are around 600 visible sprites and runs at ~215 FPS
.. at 1440p there are around 2000 visible sprites and runs at ~135 FPS
The Systems this PR adds take around 1.2ms (with 100K+ sprites in the scene)
Note:
This is only implemented for Sprites and AtlasTextureSprites.
There is no culling for 3D in this PR.
