# Objective
Fix#2406
Scene parenting was not done completely, leaving the hierarchy maintenance to the standard system. As scene spawning happens in stage `PreUpdate` and hierarchy maintenance in stage `PostUpdate`, this left the scene in an invalid state parent wise for part of a frame
## Solution
Also add/update the `Children` component when spawning the scene.
I kept the `Children` component as a `SmallVec`, it could be moved to an `HashSet` to guarantee uniqueness

# 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
- mp3 feature of rodio has dependencies that are not maintained with security issues
- mp3 feature of rodio doesn't build in wasm
- mp3 feature of rodio uses internal memory allocation that cause rejection from Apple appstore
## Solution
- Use vorbis instead of mp3 by default

WIthout the feature, `gilrs` uses `stdweb` instead of `wasm-bindgen` which isn't compatible with the rest of bevy.
Unfortunately, the `stdweb` dependency is still in the dependency tree, it just isn't used (https://gitlab.com/gilrs-project/gilrs/-/issues/101). This will be fixed in `gilrs 0.9` when it releases.
# 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
- I want to be able to use `#ifdef` and other processor directives in an imported shader
## Solution
- Process imported shader strings

# Objective
- Tentatively fixes#2525.
## Solution
- The panic seems to occur when the game-over state occurs nearly instantly.
- Discard the `Result`, rather than panicking. We could probably handle this better, but I want to see if this works first. Ping @qarmin.
# Objective
- fixes#3397
## Solution
- Uses EventWriter instead of ResMut<Event> in gilrs_system.rs.
I also renamed the argument from `event` to `events` for consistency. All other instances I could find in the engine of EventWriter use a plural argument name. Happy to undo or modify this change if desired.
# 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
The window's cursor should be settable without having to implement a custom cursor icon solution. This will especially be helpful when creating user-interfaces that might like to use the cursor to denote some meaning (e.g., _clickable_, _resizable_, etc.).
## Solution
Added a `CursorIcon` enum that maps one-to-one to winit's `CursorIcon` enum, as well as a method to set/get it for the given `Window`.
# Objective
Fixes: #3368
Issue was caused by screen size being: `(0, 0)`.
## Solution
Don't update clusters if the screen size is zero. A better solution might be to not render when minimized, but this works in the meantime.

# 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

# Objective
- Storages are used to store the ECS data.
- They're undocumented.
## Solution
- Add some very basic docs.
## Notes
- Some of this was hard to immediately understand when reading the code, so suggestions on improvements / things to add are particularly welcome.
# Objective
Fixes#3379
## Solution
The custom mesh pipelines needed to be specialized on each mesh's primitive topology, as done in `queue_meshes()`

# Objective
This PR implements the `overflow` style property in `bevy_ui`. When set to `Overflow::Hidden`, the children of that node are clipped so that overflowing parts are not rendered. This is an important building block for UI widgets.
## Solution
Clipping is done on the CPU so that it does not break batching.
The clip regions update was implemented as a separate system for clarity, but it could be merged with the other UI systems to avoid doing an additional tree traversal. (I don't think it's important until we fix the layout performance issues though).
A scrolling list was added to the `ui_pipelined` example to showcase `Overflow::Hidden`. For the sake of simplicity, it can only be scrolled with a mouse.
# 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
Fixes#2566Fixes#3005
There are only READMEs in the 4 crates here (with the exception of bevy itself).
Those 4 crates are ecs, reflect, tasks, and transform.
These should each now include their respective README files.

# Objective
I thought I'd have a go a trying to fix#2597.
Hopefully fixes#2597.
## Solution
I reused the memory pointed to by the value parameter, that is already required by `insert` to not be dropped, to contain the extracted value while dropping it.
# 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
Every time I come back to Bevy I face the same issue: how do I draw a rectangle again? How did that work? So I go to https://github.com/bevyengine/bevy/tree/main/examples in the hope of finding literally the simplest possible example that draws something on the screen without any dependency such as an image. I don't want to have to add some image first, I just quickly want to get something on the screen with `main.rs` alone so that I can continue building on from that point on. Such an example is particularly helpful for a quick start for smaller projects that don't even need any assets such as images (this is my case currently).
Currently every single example of https://github.com/bevyengine/bevy/tree/main/examples#2d-rendering (which is the first section after hello world that beginners will look for for very minimalistic and quick examples) depends on at least an asset or is too complex. This PR solves this.
It also serves as a great comparison for a beginner to realize what Bevy is really like and how different it is from what they may expect Bevy to be. For example for someone coming from [LÖVE](https://love2d.org/), they will have something like this in their head when they think of drawing a rectangle:
```lua
function love.draw()
love.graphics.setColor(0.25, 0.25, 0.75);
love.graphics.rectangle("fill", 0, 0, 50, 50);
end
```
This, of course, differs quite a lot from what you do in Bevy. I imagine there will be people that just want to see something as simple as this in comparison to have a better understanding for the amount of differences.
## Solution
Add a dead simple example drawing a blue 50x50 rectangle in the center with no more and no less than needed.
# Objective
Have the bird spawning/collision systems in bevymark use the proper window size, instead of the size set in WindowDescriptor which isn't updated when the window is resized.
## Solution
Use the Windows resource to grab the width/height from the primary window. This is consistent with the other examples.
These derives seem to be leftover vestiges of the old renderer.
At least removing them doesn't seem to harm anything.
edit: thanks `@forbjok` on discord for pointing this out.
# 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
- It isn't very useful to be able to enable feature `trace_chrome` on its own
## Solution
- Enable `trace` feature when enabling `trace_chrome` or `trace_tracy`
Co-authored-by: François <8672791+mockersf@users.noreply.github.com>
# Objective
- fixes#3344
- have example run faster
## Solution
- thanks to the nice folks at wgpu, I was able to switch from swift shader to lavapipe which is faster
- I also reduced the runtime for some of the examples
- I enabled the trace_chrome feature on the examples, and stored the results as an artefact. it can be useful to debug
- runtime is back to around 10 minutes

# 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.
# Objective
- With the removal of the old renderer, Bevy doesn't depend on spirv-reflect 🎉
## Solution
- Remove its advisory from the ignored list

# Objective
Previously, the gilrs system had no explicit relationship to the input
systems. This could potentially cause it to be scheduled after the
input systems, leading to a one-frame lag in gamepad inputs.
This was a regression introduced in #1606 which removed the `PreEvent` stage
## Solution
This adds an explicit `before` relationship to the gilrs plugin,
ensuring that raw gamepad events will be processed on the same frame
that they are generated.
Currently the `ClearPassNode` is not exported, due to an additional `use ...;` in the core pipeline's `lib.rs`. This seems unintentional, as there already is a public glob import in the file.
This just removes the explicit use. If it actually was intentional to keep the node internal, let me know.
# Objective
`KeyCode::*Win` and `KeyCode::*Alt` might be confusing for some Mac users.
## Solution
Added some small documentation to clarify the mappings for those developing on a Mac.
## Additional Context
Related issue: #3240
# Objective
This PR fixes a crash when winit is enabled when there is a camera in the world. Part of #3155
## Solution
In this PR, I removed two unwraps and added an example for regression testing.
# Objective
PBR lighting was broken in the new renderer when using orthographic projections due to the way the depth slicing works for the clusters. Fix it.
## Solution
- The default orthographic projection near plane is 0.0. The perspective projection depth slicing does a division by the near plane which gives a floating point NaN and the clustering all breaks down.
- Orthographic projections have a linear depth mapping, so it made intuitive sense to me to do depth slicing with a linear mapping too. The alternative I saw was to try to handle the near plane being at 0.0 and using the exponential depth slicing, but that felt like a hack that didn't make sense.
- As such, I have added code that detects whether the projection is orthographic based on `projection[3][3] == 1.0` and then implemented the orthographic mapping case throughout (when computing cluster AABBs, and when mapping a view space position (or light) to a cluster id in both the rust and shader code).

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.
Fixes#3043
`surface_texture.present()` will cause panics if no work is done on a given frame. "Views" are how we queue up work. Without any cameras, no work is produced. This adds a "clear pass" for windows without views, which ensures we clear windows (thus doing work) every frame.
This is a "quick fix". It can be made much cleaner once we make "render targets" a concept and move some responsibilities around. Then we just clear the "render target" once instead of clearing "views". I _might_ have time to tackle that work prior to 0.6, but I doubt it. If "render targets" don't make it in to 0.6, they will be one of the first things I tackle after release.
# Objective
Fixes#3247
## Solution
- Added docs to `Axis<T>`. This one can be extended @alice-i-cecile
- Added unit tests
- Added `min` and `max` values to the struct. @alice-i-cecile Do we need to these variables?
- Limited `set` method usage with `min` and `max` values

# Objective
Fixes#3255
## Solution
- mark the `bevy_gltf` feature as required for some examples
This should be cleaned up when we remove the old renderer
