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

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

After an inquiry on Reddit about support for Directional Lights and the unused properties on Light, I wanted to clean it up, to hopefully make it ever so slightly more clear for anyone wanting to add additional light types.

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.
I was looking into "lower level" rendering and I saw no example on how to do that. Yet, I think it's something relevant to show, so I set up a simple example on how to do that. I hope it's welcome.
I'm not confident about the code and a review is definitely nice to have, especially because there are a few things that are not great.
Specifically, I think it would be nice to see how to render with a completely custom set of attributes (position and color, in this case), but I couldn't manage to get it working without normals and uv.
It makes sense if bevy Meshes need these two attributes, but I'm not sure about it.

This PR fixes https://github.com/bevyengine/bevy/issues/1240, where the ball is escaping the playing field at low framerates. I did this by moving the movement and physics system into a Fixed Timestep system set and changing the movement steps to a constant. So we lose the example use of delta_time for changing position, but gain a use of FixedTimestep.
If this is accepted https://github.com/bevyengine/bevy-website/pull/102 will need to be updated to match.

This reduces the size of executables when using bevy as dylib by
ensuring that they get codegened in bevy_assets instead of the game
itself. This by extension avoids pulling in parts of bevy_tasks and
async_task.
Before this change the breakout example was 923k big after this change
it is only 775k big for cg_clif. For cg_llvm in release mode breakout
shrinks from 356k to 316k. For cg_llvm in debug mode breakout shrinks
from 3814k to 3057k.
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
<img width="1407" alt="Screenshot 2021-04-02 at 02 57 14" src="https://user-images.githubusercontent.com/8672791/113368551-5a3c2780-935f-11eb-8c8d-e9ba65b5ee98.png">
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
fixes#1772
1st commit: the limit was at 11 as the macro was not using a range including the upper end. I changed that as it feels the purpose of the macro is clearer that way.
2nd commit: as suggested in the `// TODO`, I added a `Config` trait to go to 16 elements tuples. This means that if someone has a custom system parameter with a config that is not a tuple or an `Option`, they will have to implement `Config` for it instead of the standard `Default`.
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 is a temporary fix for the CI (and anyone building for wasm) break until `wgpu` can update
* `syn` released a version that fixed a bug in how they parsed attributes
* `wasm_bindgen` released a version that uses that fix
* but we're stuck with old `wasm_bindgen` as `wgpu` uses a fixed version: c5ee9cd983/Cargo.toml (L118)
So, to fix this, either we update everyone to latest version of `wasm_bindgen` or we keep using old version of `syn`.
On Bevy side, it should be faster to fix the version of `syn` to one that works.
More details: https://github.com/rustwasm/wasm-bindgen/pull/2510 & https://github.com/rustwasm/wasm-bindgen/issues/2508
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.

The only API to add a parent/child relationship between existing entities is through commands, there is no easy way to do it from `World`. Manually inserting the components is not completely possible since `PreviousParent` has no public constructor.
This PR adds two methods to set entities as children of an `EntityMut`: `insert_children` and `push_children`. ~~The API is similar to the one on `Commands`, except that the parent is the `EntityMut`.~~ The API is the same as in #1703.
However, the `Parent` and `Children` components are defined in `bevy_transform` which depends on `bevy_ecs`, while `EntityMut` is defined in `bevy_ecs`, so the methods are added to the `BuildWorldChildren` trait instead.
If #1545 is merged this should be fixed too.
I'm aware cart was experimenting with entity hierarchies, but unless it's a coming soon this PR would be useful to have meanwhile.

Load textures from gltf as linear when needed.
This is for #1632, but can be done independently and won't have any visible impact before.
* during iteration over materials, register textures that need to be loaded as linear
* during iteration over textures
* directly load bytes from external files instead of adding them as dependencies in the load context
* configure the texture the same way for buffered and external textures
* if the texture is linear rgb, set as linear rgb
Fixes#1753.
The problem was introduced while reworking the logic around stages' own criteria. Before #1675 they used to be stored and processed inline with the systems' criteria, and systems without criteria used that of their stage. After, criteria-less systems think they should run, always. This PR more or less restores previous behavior; a less cludge solution can wait until after 0.5 - ideally, until stageless.

Frustum culling has some pretty major gaps right now (such as not supporting sprite transform scaling and not taking into account projections). It should be disabled by default until it provides a solid experience across all bevy use cases.
