# 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.

# 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.

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.

* 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.

From 'fintelia' on the Bevy Render Rework Round 2 discussion:
"My understanding is that GPUs these days never use the "execute both branches
and select the result" strategy. Rather, what they do is evaluate the branch
condition on all threads of a warp, and jump over it if all of them evaluate to
false. If even a single thread needs to execute the if statement body, however,
then the remaining threads are paused until that is completed."
* bevy_pbr2: Simplify texture and sampler names
The StandardMaterial_ prefix is no longer needed
* bevy_pbr2: Match default 'AmbientColor' of current bevy_pbr for now

* bevy_pbr2: Add AmbientLight resource
* bevy_pbr2: Convert PointLight color to linear sRGB for use in fragment shader
* bevy_pbr2: pbr.frag: Rename PointLight.projection to view_projection
The uniform contains the view_projection matrix so this was incorrect.
* bevy_pbr2: PointLight is an OmniLight as it has a radius
* bevy_pbr2: Factoring out duplicated code
* bevy_pbr2: Implement RenderAsset for StandardMaterial
* Remove unnecessary texture and sampler clones
* fix comment formatting

* Don't extract meshes when their material textures aren't ready
* make missing textures in the queue step an error

# Objective
Noticed a warning when running tests:
```
> cargo test --workspace
warning: output filename collision.
The example target `change_detection` in package `bevy_ecs v0.5.0 (/bevy/crates/bevy_ecs)` has the same output filename as the example target `change_detection` in package `bevy v0.5.0 (/bevy)`.
Colliding filename is: /bevy/target/debug/examples/change_detection
The targets should have unique names.
Consider changing their names to be unique or compiling them separately.
This may become a hard error in the future; see <https://github.com/rust-lang/cargo/issues/6313>.

## Solution
I renamed example `change_detection` to `component_change_detection`
# Objective
- Extend work done in #2398.
- Make `.system()` syntax optional when using system descriptor API.
## Solution
- Slight change to `ParallelSystemDescriptorCoercion` signature and implementors.

I haven't touched exclusive systems, because it looks like the only two other solutions are going back to doubling our system insertion methods, or starting to lean into stageless. The latter will invalidate the former, so I think exclusive systems should remian pariahs until stageless.
I can grep & nuke `.system()` thorughout the codebase now, which might take a while, or we can do that in subsequent PR(s).
This can be your 6 months post-christmas present.
# Objective
- Make `.system` optional
- yeet
- It's ugly
- Alternative title: `.system` is dead; long live `.system`
- **yeet**
## Solution
- Use a higher ranked lifetime, and some trait magic.
N.B. This PR does not actually remove any `.system`s, except in a couple of examples. Once this is merged we can do that piecemeal across crates, and decide on syntax for labels.
I'm still here :) will try to land the ios audio support in cpal soon and then we can land this.
This PR also adds in assets as a directory reference and avoids the "Xcode is optimizing and breaking my PNGs" issue that I had earlier on during iOS testing on Bevy.
Re-testing this now.

With const generics, it is now possible to write generic iterator over multiple entities at once.
This enables patterns of query iterations like
```rust
for [e1, e2, e3] in query.iter_combinations() {
// do something with relation of all three entities
}
```
The compiler is able to infer the correct iterator for given size of array, so either of those work
```rust
for [e1, e2] in query.iter_combinations() { ... }
for [e1, e2, e3] in query.iter_combinations() { ... }
```
This feature can be very useful for systems like collision detection.
When you ask for permutations of size K of N entities:
- if K == N, you get one result of all entities
- if K < N, you get all possible subsets of N with size K, without repetition
- if K > N, the result set is empty (no permutation of size K exist)

Fixes the frag shader for unlit materials by correcting the scope of the `#ifndef` to include the light functions. Closes#2190, introduced in #2112.
Tested by changing materials in the the `3d_scene` example to be unlit. Unsure how to prevent future regressions without creating a test case scene that will catch these runtime panics.
This covers issue #2110
It adds the line `.add_system(bevy::input::system::exit_on_esc_system.system())` before `.run()`
to every example that uses a window, so users have a quick way to close the examples.
I used the full name `bevy::input::system::exit_on_esc_system`, I thought it gave clarity about being a built-in system.
The examples excluded from the change are the ones in the android, ios, wasm folders, the headless
examples and the ecs/system_sets example because it closes itself.
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

In response to #2023, here is a draft for a PR.
Fixes#2023
I've added an example to show how to use `WithBundle`, and also to test it out.
Right now there is a bug: If a bundle and a query are "the same", then it doesn't filter out
what it needs to filter out.
Example:
```
Print component initated from bundle.
[examples/ecs/query_bundle.rs:57] x = Dummy( <========= This should not get printed
111,
)
[examples/ecs/query_bundle.rs:57] x = Dummy(
222,
)
Show all components
[examples/ecs/query_bundle.rs:50] x = Dummy(
111,
)
[examples/ecs/query_bundle.rs:50] x = Dummy(
222,
)
```
However, it behaves the right way, if I add one more component to the bundle,
so the query and the bundle doesn't look the same:
```
Print component initated from bundle.
[examples/ecs/query_bundle.rs:57] x = Dummy(
222,
)
Show all components
[examples/ecs/query_bundle.rs:50] x = Dummy(
111,
)
[examples/ecs/query_bundle.rs:50] x = Dummy(
222,
)
```
I hope this helps. I'm definitely up for tinkering with this, and adding anything that I'm asked to add
or change.

If accepted, fixes#1694 .
I wanted to explore system sets and run criteria a bit, so made an example expanding a bit on the snippets shown in the 0.5 release post.
Shows a couple of system sets, uses system labels, run criterion, and a use of the interesting `RunCriterion::pipe` functionality.
Fixes#1895
Changed most `println` to `info` in examples, some to `warn` when it was useful to differentiate from other more noisy logs.
Added doc on `LogPlugin`, how to configure it, and why (and how) you may need to disable it
This was nowhere documented inside Bevy.
Should I also mention the use case of debugging a project?
Closes#810

Just to avoid confusion to close readers of the example, this fix ensures cake is transformed to the height at the cake's cell, rather than the height at the player's cell.
Without this, cake may be floating or buried, depending on where the player is standing at time of spawning.
Love your work!
This PR adds an example on how to animate a shader by passing the global `time.seconds_since_startup()` to a component, and accessing that component inside the shader.
Hopefully this is the current proper solution, please let me know if it should be solved in another way.

Direction of movement was reversed, previously.
(i.e. Left arrow key moved sprite to the right; Right arrow key moved sprite to the left.)
This PR changes the code to now be consistent with, for example, the breakout example: 81b53d15d4/examples/game/breakout.rs (L184-L190)
i.e. AFAICT it's not an issue with the keycode being different/wrong.
