Some panic messages for systems include the system name, but there's a few panic messages which do not. This PR adds the system name for the remaining panic messages.
This is a continuation of the work done in #1864.
Related: #1846
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
Closes https://github.com/bevyengine/bevy/issues/1579
This is my first contribution to this repository, feel free to correct anything that I'm missing and I'll address feedback as soon as possible!
This shrinks breakout from 316k to 310k when using `--feature dynamic`.
I haven't run the ecs benchmark to test performance as my laptop is too noisy for reliable benchmarking.
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
After running `bevy_core` through `miri`, errors were reported surrounding incorrect memory accesses within the `bytes` test suit.
Specifically:
```
test bytes::tests::test_array_round_trip ... error: Undefined Behavior: accessing memory with alignment 1, but alignment 4 is required
--> crates/bevy_core/src/bytes.rs:55:13
|
55 | (*ptr).clone()
| ^^^^^^ accessing memory with alignment 1, but alignment 4 is required
|
```
and
```
test bytes::tests::test_vec_bytes_round_trip ... error: Undefined Behavior: accessing memory with alignment 2, but alignment 4 is required
--> /home/nward/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/core/src/slice/raw.rs:95:14
|
95 | unsafe { &*ptr::slice_from_raw_parts(data, len) }
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ accessing memory with alignment 2, but alignment 4 is required
|
```
Solution:
The solution is to use `slice::align_to` method to ensure correct alignment.
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);
```

This was nowhere documented inside Bevy.
Should I also mention the use case of debugging a project?

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],
}
```
