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!
We discussed with @alice-i-cecile privately on iterators and agreed that making a custom ordered iterator over query makes no sense since materialization is required anyway and it's better to reuse existing components or code. Therefore, just adding an example to the documentation as requested.
Fixes#1470.

Introduced in #1778, not fixed by #1931
The size of `Lights` buffer currently is :
```rust
16 // (color, `[f32; 4]`)
+ 16 // (number of lights, `f32` encoded as a `[f32; 4]`)
+ 10 // (maximum number of lights)
* ( 16 // (light position, `[f32; 4]`
+ 16 // (color, `[16; 4]`)
+ 4 // (inverse_range_squared, `f32`)
)
-> 392
```
This makes the pbr shader crash when running with Xcode debugger or with the WebGL2 backend. They both expect a buffer sized 512. This can also be seen on desktop by adding a second light to a scene with a color, it's position and color will be wrong.
adding a second light to example `load_gltf`:
```rust
commands
.spawn_bundle(PointLightBundle {
transform: Transform::from_xyz(-3.0, 5.0, -3.0),
point_light: PointLight {
color: Color::BLUE,
..Default::default()
},
..Default::default()
})
.insert(Rotates);
```

This PR changes `inverse_range_squared` to be a `[f32; 4]` instead of a `f32` to have the expected alignement
Fixes#1921
Buffer was growing with the actual number of lights instead of being limited to the max number of lights.
As it's a query that can be exactly sized, I also switched `count()` to `len()`
This includes a lot of single line comments where either saying more wasn't helpful or due to me not knowing enough about things yet to be able to go more indepth. Proofreading is very much welcome.
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.

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.
I've had problems with compiling and running the pbr example:
```
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Compilation("glslang_shader_preprocess:\nInfo log:\nERROR: 0:40: \'#version\' : must occur first in shader \nERROR: 0:40: \'#version\' : bad profile name; use es, core, or compatibility \nERROR: 0:40: \'#version\' : bad tokens following profile -- expected newline \nERROR: 3 compilation errors. No code generated.\n\n\nDebug log:\n\n")', crates/bevy_render/src/pipeline/pipeline_compiler.rs:161:22
```
I've checked each shader, and only one shader hasn't had `#version` in the first line.
This change fixed my issue.
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.
Fixes#1846
Got scared of the other "Requested resource does not exist" error at line 395 in `system_param.rs`, under `impl<'a, T: Component> SystemParamFetch<'a> for ResMutState<T> {`. Someone with better knowledge of the code might be able to go in and improve that one.
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],
}
```
The g++ package may not be preinstalled.
Also, replaced the mention of "fast" compiles, with generic instructions about how to install clang; this is because on my test system, clang didn't make any difference, and it's likely not to do any in general, as it is a relatively small part of the build.
Closes#1294.
From suggestion from Godot workflows: https://github.com/bevyengine/bevy/issues/1730#issuecomment-810321110
* Add a feature `bevy_debug` that will make Bevy read a debug config file to setup some debug systems
* Currently, only one that will exit after x frames
* Could add option to dump screen to image file once that's possible
* Add a job in CI workflow that will run a few examples using [`swiftshader`](https://github.com/google/swiftshader)
* This job takes around 13 minutes, so doesn't add to global CI duration
|example|number of frames|duration|
|-|-|-|
|`alien_cake_addict`|300|1:50|
|`breakout`|1800|0:44|
|`contributors`|1800|0:43|
|`load_gltf`|300|2:37|
|`scene`|1800|0:44|
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 existing issue templates don't fit well for "the docs are not very good" and are too high friction.
This is intended as a very-low friction tool to provide the basis for more thorough docs PRs.
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.
related to #1700
This PR:
* documents all methods on `Input<T>`
* adds documentation on the struct about how to use it, and how to implement it for a new input type
* renames method `update` to a easier to understand `clear`
* adds two methods to check for state and clear it after, allowing easier use in the case of #1700

- prints glsl compile error message in multiple lines instead of `thread 'main' panicked at 'called Result::unwrap() on an Err value: Compilation("glslang_shader_parse:\nInfo log:\nERROR: 0:335: \'assign\' : l-value required \"anon@7\" (can\'t modify a uniform)\nERROR: 0:335: \'\' : compilation terminated \nERROR: 2 compilation errors. No code generated.\n\n\nDebug log:\n\n")', crates/bevy_render/src/pipeline/pipeline_compiler.rs:161:22`
- makes gltf error messages have more context
New error:
```rust

These changes are a bit unrelated. I can open separate PRs if someone wants that.
