# Objective
- A scene usually gets created using the `SceneBundle` or
`DynamicSceneBundle`. This means that the scene's entities get added as
children of the root entity (the entity on which the `SceneBundle` gets
added)
- When the scene gets deleted using the `SceneSpawner`, the scene's
entities are deleted, but the `Children` component of the root entity
doesn't get updated. This means that the hierarchy becomes unsound, with
Children linking to non-existing components.
## Solution
- Update the `despawn_sync` logic to also update the `Children` from any
parents of the scene, if there are any
- Adds a test where a Scene gets despawned and checks for dangling
Children references on the parent. The test fails on `main` but works
here.
## Alternative implementations
- One option could be to add a `parent: Option<Entity>` on the
[InstanceInfo](df15cd7dcc/crates/bevy_scene/src/scene_spawner.rs (L27))
struct that tracks if the SceneInstance was added as a child of a root
entity
# Objective
When I wrote #12747 I neglected to translate random samples from
triangles back to the point where they originated, so they would be
sampled near the origin instead of at the actual triangle location.
## Solution
Translate by the first vertex location so that the samples follow the
actual triangle.
# Objective

# Objective
Fix#12728. Fix unsoundnesss from unhandled null characters in Android
logs.
## Solution
Use `CString` instead of using formatted Strings. Properly document the
safety invariants of the FFI call.
# Objective
- Move `PanicHandlerPlugin` into `bevy_app`
- Fixes#12603 .
## Solution
- I moved the `bevy_panic_handler` into `bevy_app`
- Copy pasted `bevy_panic_handler`'s lib.rs into a separate module in
`bevy_app` as a `panic_handler.rs` module file and added the
`PanicHandlerPlugin` in lib.rs of `bevy_app`
- added the dependency into `cargo.toml`
## Review notes
- I probably want some feedback if I imported App and Plugin correctly
in `panic_handler.rs` line 10 and 11.
- As of yet I have not deleted `bevy_panic_handler` crate, wanted to get
a check if I added it correctly.
- Once validated that my move was correct, I'll probably have to remove
the panic handler find default plugins which I probably need some help
to find.
- And then remove bevy panic_handler and making sure ci passes.
- This is my first issue for contributing to bevy so let me know if I am
doing anything wrong.
## tools context
- rust is 1.76 version

- Avoid unbounded HashMap growth for opening/closing windows.
## Solution
- Remove map entry in `WinitWindows::remove_window`.
## Migration Guide
- `WinitWindows::get_window_entity` now returns `None` after a window is
closed, instead of a dead entity.
---
## Comments
The comment this PR replaces was added in
https://github.com/bevyengine/bevy/pull/3575. Since `get_window_entity`
now returns an `Entity` instead of a `WindowId`, this no longer seems
useful. Note that `get_window_entity` is only used
[here](56bcbb0975/crates/bevy_winit/src/lib.rs (L436)),
immediately followed by a warning if the entity returned doesn't exist.
# Objective
- Fixes#12677
## Solution
Updated documentation to make it explicit that enabling the appropriate
optional features is required to use the supported audio file format, as
well as provided link to the Bevy docs listing the optional features.

## Solution
- Properly declare the push constant as in

## Problem
- A mutable borrow of a handle cannot be directly turned into an AssetId
with `.into()`. You must do a reborrow `&*my_handle`.
## Solution
- Add an impl for From<&mut Handle> to AssetId and UntypedAssetId.
# Objective
Previously, the `Point` trait, which abstracts all of the operations of
a real vector space, was sitting in the submodule of `bevy_math` for
cubic splines. However, the trait has broader applications than merely
cubic splines, and we should use it when possible to avoid code
duplication when performing vector operations.
## Solution
`Point` has been moved into a new submodule in `bevy_math` named
`common_traits`. Furthermore, it has been renamed to `VectorSpace`,
which is more descriptive, and an additional trait `NormedVectorSpace`
has been introduced to expand the API to cover situations involving
geometry in addition to algebra. Additionally, `VectorSpace` itself now
requires a `ZERO` constant and `Neg`. It also supports a `lerp` function
as an automatic trait method.
Here is what that looks like:
```rust
/// A type that supports the mathematical operations of a real vector space, irrespective of dimension.
/// In particular, this means that the implementing type supports:
/// - Scalar multiplication and division on the right by elements of `f32`
/// - Negation
/// - Addition and subtraction
/// - Zero
///
/// Within the limitations of floating point arithmetic, all the following are required to hold:
/// - (Associativity of addition) For all `u, v, w: Self`, `(u + v) + w == u + (v + w)`.
/// - (Commutativity of addition) For all `u, v: Self`, `u + v == v + u`.
/// - (Additive identity) For all `v: Self`, `v + Self::ZERO == v`.
/// - (Additive inverse) For all `v: Self`, `v - v == v + (-v) == Self::ZERO`.
/// - (Compatibility of multiplication) For all `a, b: f32`, `v: Self`, `v * (a * b) == (v * a) * b`.
/// - (Multiplicative identity) For all `v: Self`, `v * 1.0 == v`.
/// - (Distributivity for vector addition) For all `a: f32`, `u, v: Self`, `(u + v) * a == u * a + v * a`.
/// - (Distributivity for scalar addition) For all `a, b: f32`, `v: Self`, `v * (a + b) == v * a + v * b`.
///
/// Note that, because implementing types use floating point arithmetic, they are not required to actually
/// implement `PartialEq` or `Eq`.
pub trait VectorSpace:
Mul<f32, Output = Self>
+ Div<f32, Output = Self>
+ Add<Self, Output = Self>
+ Sub<Self, Output = Self>
+ Neg
+ Default
+ Debug
+ Clone
+ Copy
{
/// The zero vector, which is the identity of addition for the vector space type.
const ZERO: Self;
/// Perform vector space linear interpolation between this element and another, based
/// on the parameter `t`. When `t` is `0`, `self` is recovered. When `t` is `1`, `rhs`
/// is recovered.
///
/// Note that the value of `t` is not clamped by this function, so interpolating outside
/// of the interval `[0,1]` is allowed.
#[inline]
fn lerp(&self, rhs: Self, t: f32) -> Self {
*self * (1. - t) + rhs * t
}
}
```
```rust
/// A type that supports the operations of a normed vector space; i.e. a norm operation in addition
/// to those of [`VectorSpace`]. Specifically, the implementor must guarantee that the following
/// relationships hold, within the limitations of floating point arithmetic:
/// - (Nonnegativity) For all `v: Self`, `v.norm() >= 0.0`.
/// - (Positive definiteness) For all `v: Self`, `v.norm() == 0.0` implies `v == Self::ZERO`.
/// - (Absolute homogeneity) For all `c: f32`, `v: Self`, `(v * c).norm() == v.norm() * c.abs()`.
/// - (Triangle inequality) For all `v, w: Self`, `(v + w).norm() <= v.norm() + w.norm()`.
///
/// Note that, because implementing types use floating point arithmetic, they are not required to actually
/// implement `PartialEq` or `Eq`.
pub trait NormedVectorSpace: VectorSpace {
/// The size of this element. The return value should always be nonnegative.
fn norm(self) -> f32;
/// The squared norm of this element. Computing this is often faster than computing
/// [`NormedVectorSpace::norm`].
#[inline]
fn norm_squared(self) -> f32 {
self.norm() * self.norm()
}
/// The distance between this element and another, as determined by the norm.
#[inline]
fn distance(self, rhs: Self) -> f32 {
(rhs - self).norm()
}
/// The squared distance between this element and another, as determined by the norm. Note that
/// this is often faster to compute in practice than [`NormedVectorSpace::distance`].
#[inline]
fn distance_squared(self, rhs: Self) -> f32 {
(rhs - self).norm_squared()
}
}
```
Furthermore, this PR also demonstrates the use of the
`NormedVectorSpace` combined API to implement `ShapeSample` for
`Triangle2d` and `Triangle3d` simultaneously. Such deduplication is one
of the drivers for developing these APIs.
---
## Changelog
- `Point` from `cubic_splines` becomes `VectorSpace`, exported as
`bevy::math::VectorSpace`.
- `VectorSpace` requires `Neg` and `VectorSpace::ZERO` in addition to
its existing prerequisites.
- Introduced public traits `bevy::math::NormedVectorSpace` for generic
geometry tasks involving vectors.
- Implemented `ShapeSample` for `Triangle2d` and `Triangle3d`.
## Migration Guide
Since `Point` no longer exists, any projects using it must switch to
`bevy::math::VectorSpace`. Additionally, third-party implementations of
this trait now require the `Neg` trait; the constant `VectorSpace::ZERO`
must be provided as well.
---
## Discussion
### Design considerations
Originally, the `NormedVectorSpace::norm` method was part of a separate
trait `Normed`. However, I think that was probably too broad and, more
importantly, the semantics of having it in `NormedVectorSpace` are much
clearer.
As it currently stands, the API exposed here is pretty minimal, and
there is definitely a lot more that we could do, but there are more
questions to answer along the way. As a silly example, we could
implement `NormedVectorSpace::length` as an alias for
`NormedVectorSpace::norm`, but this overlaps with methods in all of the
glam types, so we would want to make sure that the implementations are
effectively identical (for what it's worth, I think they are already).
### Future directions
One example of something that could belong in the `NormedVectorSpace`
API is normalization. Actually, such a thing previously existed on this
branch before I decided to shelve it because of concerns with namespace
collision. It looked like this:
```rust
/// This element, but normalized to norm 1 if possible. Returns an error when the reciprocal of
/// the element's norm is not finite.
#[inline]
#[must_use]
fn normalize(&self) -> Result<Self, NonNormalizableError> {
let reciprocal = 1.0 / self.norm();
if reciprocal.is_finite() {
Ok(*self * reciprocal)
} else {
Err(NonNormalizableError { reciprocal })
}
}
/// An error indicating that an element of a [`NormedVectorSpace`] was non-normalizable due to having
/// non-finite norm-reciprocal.
#[derive(Debug, Error)]
#[error("Element with norm reciprocal {reciprocal} cannot be normalized")]
pub struct NonNormalizableError {
reciprocal: f32
}
```
With this kind of thing in hand, it might be worth considering
eventually making the passage from vectors to directions fully generic
by employing a wrapper type. (Of course, for our concrete types, we
would leave the existing names in place as aliases.) That is, something
like:
```rust
pub struct NormOne<T>
where T: NormedVectorSpace { //... }
```
Utterly separately, the reason that I implemented `ShapeSample` for
`Triangle2d`/`Triangle3d` was to prototype uniform sampling of abstract
meshes, so that's also a future direction.

# Objective
Fix the use of `TypeRegistry` instead of `TypeRegistryArc` in dynamic
scene and its serializer.
Rename `DynamicScene::serialize_ron()` into `serialize()` to highlight
the fact this is not about serializing to RON specifically, but rather
about serializing to the official Bevy scene format (`.scn` /
`.scn.ron`) which the `SceneLoader` can deserialize (and which happens
to be based in RON, but that not the object here). Also make the link
with the documentation of `SceneLoader` so users understand the full
serializing cycle of a Bevy dynamic scene.
Document `SceneSerializer` with an example showing how to serialize to a
custom format (here: RON), which is easily transposed to serializing
into any other format.
Fixes#9520
## Changelog
### Changed
* `SceneSerializer` and all related serializing helper types now take a
`&TypeRegistry` instead of a `&TypeRegistryArc`. ([SceneSerializer
needlessly uses specifically
&TypeRegistryArc #9520](https://github.com/bevyengine/bevy/issues/9520))
* `DynamicScene::serialize_ron()` was renamed to `serialize()`.
## Migration Guide
* `SceneSerializer` and all related serializing helper types now take a
`&TypeRegistry` instead of a `&TypeRegistryArc`. You can upgrade by
getting the former from the latter with `TypeRegistryArc::read()`,
_e.g._
```diff
let registry_arc: TypeRegistryArc = [...];
- let serializer = SceneSerializer(&scene, ®istry_arc);
+ let registry = registry_arc.read();
+ let serializer = SceneSerializer(&scene, ®istry);
```
* Rename `DynamicScene::serialize_ron()` to `serialize()`.

# Objective
Resolves#3824. `unsafe` code should be the exception, not the norm in
Rust. It's obviously needed for various use cases as it's interfacing
with platforms and essentially running the borrow checker at runtime in
the ECS, but the touted benefits of Bevy is that we are able to heavily
leverage Rust's safety, and we should be holding ourselves accountable
to that by minimizing our unsafe footprint.
## Solution
Deny `unsafe_code` workspace wide. Add explicit exceptions for the
following crates, and forbid it in almost all of the others.
* bevy_ecs - Obvious given how much unsafe is needed to achieve
performant results
* bevy_ptr - Works with raw pointers, even more low level than bevy_ecs.
* bevy_render - due to needing to integrate with wgpu
* bevy_window - due to needing to integrate with raw_window_handle
* bevy_utils - Several unsafe utilities used by bevy_ecs. Ideally moved
into bevy_ecs instead of made publicly usable.
* bevy_reflect - Required for the unsafe type casting it's doing.
* bevy_transform - for the parallel transform propagation
* bevy_gizmos - For the SystemParam impls it has.
* bevy_assets - To support reflection. Might not be required, not 100%
sure yet.
* bevy_mikktspace - due to being a conversion from a C library. Pending
safe rewrite.
* bevy_dynamic_plugin - Inherently unsafe due to the dynamic loading
nature.
Several uses of unsafe were rewritten, as they did not need to be using
them:
* bevy_text - a case of `Option::unchecked` could be rewritten as a
normal for loop and match instead of an iterator.
* bevy_color - the Pod/Zeroable implementations were replaceable with
bytemuck's derive macros.
# Objective
- `FloatOrd` currently has a different comparison behavior between its
derived `PartialOrd` impl and manually implemented `Ord` impl (The
[`Ord` doc](https://doc.rust-lang.org/std/cmp/trait.Ord.html) says this
is a logic error). This might be a problem for some `std`
containers/algorithms if they rely on both matching, and a footgun for
Bevy users.
## Solution
- Replace the `PartialEq` and `Ord` impls of `FloatOrd` with some
equivalent ones producing [better
assembly.](https://godbolt.org/z/jaWbjnMKx)
- Manually derive `PartialOrd` with the same behavior as `Ord`,
implement the comparison operators.
- Add some tests.
I first tried using a match-based implementation similar to the
`PartialOrd` impl [of the
std](https://doc.rust-lang.org/src/core/cmp.rs.html#1457) (with added
NaN ordering) but I couldn't get it to produce non-branching assembly.
The current implementation is based on [the one from the `ordered_float`
crate](3641f59e31/src/lib.rs (L121)),
adapted since it uses a different ordering. Should this be mentionned
somewhere in the code?
---
## Changelog
### Fixed
- `FloatOrd` now uses the same ordering for its `PartialOrd` and `Ord`
implementations.
## Migration Guide
- If you were depending on the `PartialOrd` behaviour of `FloatOrd`, it
has changed from matching `f32` to matching `FloatOrd`'s `Ord` ordering,
never returning `None`.
# Objective
We have `ReflectSerializer` and `TypedReflectSerializer`. The former is
the one users will most often use since the latter takes a bit more
effort to deserialize.
However, our deserializers are named `UntypedReflectDeserializer` and
`TypedReflectDeserializer`. There is no obvious indication that
`UntypedReflectDeserializer` must be used with `ReflectSerializer` since
the names don't quite match up.
## Solution
Rename `UntypedReflectDeserializer` back to `ReflectDeserializer`
(initially changed as part of #5723).
Also update the docs for both deserializers (as they were pretty out of
date) and include doc examples.
I also updated the docs for the serializers, too, just so that
everything is consistent.
---
## Changelog
- Renamed `UntypedReflectDeserializer` to `ReflectDeserializer`
- Updated docs for `ReflectDeserializer`, `TypedReflectDeserializer`,
`ReflectSerializer`, and `TypedReflectSerializer`
## Migration Guide
`UntypedReflectDeserializer` has been renamed to `ReflectDeserializer`.
Usages will need to be updated accordingly.
```diff
- let reflect_deserializer = UntypedReflectDeserializer::new(®istry);
+ let reflect_deserializer = ReflectDeserializer::new(®istry);

# Objective
I found that some .rs files are unnecessarily executable.
Rust source files may start with a shebang-like statement `#!`, so let's
make sure they are not executable just in case.
Here is the result of the `find` commend that lists executable .rs files
as of main branch `86bd648`.
```console
$ find -name \*.rs -type f -executable

./crates/bevy_tasks/src/lib.rs
./crates/bevy_time/src/lib.rs
./crates/bevy_transform/src/lib.rs
./src/lib.rs
```
It appears that the permissions of those files were originally 644, but
were unexpectedly changed to 755 by commit
52e3f2007b.

Fix the regression for Root Node's Layout behavior introduced in
https://github.com/bevyengine/bevy/pull/12268
- Add regression test for Root Node Layout's behaving as they did before
0.13.1
- Restore pre 0.13.1 Root Node Layout behavior (fixes
https://github.com/bevyengine/bevy/issues/12624)
## Solution
This implements [@nicoburns suggestion

where instead of adding the camera to the taffy node tree, we revert
back to adding a new "parent" node for each root node while maintaining
their relationship with the camera.
> If you can do the ecs change detection to move the node to the correct
Taffy instance for the camera then you should also be able to move it to
a `Vec` of root nodes for that camera.

## Changelog
Fixed https://github.com/bevyengine/bevy/issues/12624 - Restores pre
0.13.1 Root Node Layout behavior
## Migration Guide
If you were affected by the 0.13.1 regression and added `position_type:
Absolute` to all your root nodes you might be able to reclaim some LOC
by removing them now that the 0.13 behavior is restored.
# Objective
- Adds line styles to bevy gizmos, suggestion of #9400
- Currently solid and dotted lines are implemented but this can easily
be extended to support dashed lines as well if that is wanted.
## Solution
- Adds the enum `GizmoLineStyle` and uses it in each `GizmoConfig` to
configure the style of the line.
- Each "dot" in a dotted line has the same width and height as the
`line_width` of the corresponding line.
---
## Changelog
- Added `GizmoLineStyle` to `bevy_gizmos`
- Added a `line_style: GizmoLineStyle ` attribute to `GizmoConfig`
- Updated the `lines.wgsl` shader and the pipelines accordingly.
## Migration Guide
- Any manually created `GizmoConfig` must now include the `line_style`
attribute
## Additional information
Some pretty pictures :)
This is the 3d_gizmos example with/without `line_perspective`:

# Objective
This gets Bevy building on Wasm when the `atomics` flag is enabled. This
does not yet multithread Bevy itself, but it allows Bevy users to use a
crate like `wasm_thread` to spawn their own threads and manually
parallelize work. This is a first step towards resolving #4078 . Also
fixes#9304.
This provides a foothold so that Bevy contributors can begin to think
about multithreaded Wasm's constraints and Bevy can work towards changes
to get the engine itself multithreaded.
Some flags need to be set on the Rust compiler when compiling for Wasm
multithreading. Here's what my build script looks like, with the correct
flags set, to test out Bevy examples on web:
```bash
set -e
RUSTFLAGS='-C target-feature=+atomics,+bulk-memory,+mutable-globals' \
cargo build --example breakout --target wasm32-unknown-unknown -Z build-std=std,panic_abort --release
wasm-bindgen --out-name wasm_example \
--out-dir examples/wasm/target \
--target web target/wasm32-unknown-unknown/release/examples/breakout.wasm
devserver --header Cross-Origin-Opener-Policy='same-origin' --header Cross-Origin-Embedder-Policy='require-corp' --path examples/wasm
```
A few notes:
1. `cpal` crashes immediately when the `atomics` flag is set. That is
patched in https://github.com/RustAudio/cpal/pull/837, but not yet in
the latest crates.io release.
That can be temporarily worked around by patching Cpal like so:
```toml
[patch.crates-io]
cpal = { git = "https://github.com/RustAudio/cpal" }
```
2. When testing out `wasm_thread` you need to enable the `es_modules`
feature.
## Solution
The largest obstacle to compiling Bevy with `atomics` on web is that
`wgpu` types are _not_ Send and Sync. Longer term Bevy will need an
approach to handle that, but in the near term Bevy is already configured
to be single-threaded on web.
Therefor it is enough to wrap `wgpu` types in a
`send_wrapper::SendWrapper` that _is_ Send / Sync, but panics if
accessed off the `wgpu` thread.
---
## Changelog
- `wgpu` types that are not `Send` are wrapped in
`send_wrapper::SendWrapper` on Wasm + 'atomics'
- CommandBuffers are not generated in parallel on Wasm + 'atomics'

- Bevy should probably add CI checks to make sure this doesn't regress.
Should that go in this PR or a separate PR? **Edit:** Added checks to
build Wasm with atomics

# Objective
This PR fixes#12125
## Solution
The logic in this PR was borrowed from gloo-net and essentially probes
the global Javascript context to see if we are in a window or a worker
before calling `fetch_with_str`.

# Objective
Currently the built docs only shows the logo and favicon for the top
level `bevy` crate. This makes views like
https://docs.rs/bevy_ecs/latest/bevy_ecs/ look potentially unrelated to
the project at first glance.
## Solution
Reproduce the docs attributes for every crate that Bevy publishes.
Ideally this would be done with some workspace level Cargo.toml control,
but AFAICT, such support does not exist.
# Objective
Make it easy to get the ids of all the components in a bundle (and
initialise any components not yet initialised). This is fairly similar
to the `Bundle::get_component_ids()` method added in the observers PR
however that will return none for any non-initialised components. This
is exactly the API space covered by `Bundle::component_ids()` however
that isn't possible to call outside of `bevy_ecs` as it requires `&mut
Components` and `&mut Storages`.
## Solution
Added `World.init_bundle<B: Bundle>()` which similarly to
`init_component` and `init_resource`, initialises all components in the
bundle and returns a vector of their component ids.
---
## Changelog
Added the method `init_bundle` to `World` as a counterpart to
`init_component` and `init_resource`.

# Objective
- Add serialize feature to bevy_color
- "Fixes #12527".
## Solution
- Added feature for serialization
---
## Changelog
- Serde serialization is now optional, with flag 'serialize'
## Migration Guide
- If user wants color data structures to be serializable, then
application needs to be build with flag 'serialize'
# Objective
- Tiny PR to clarify that `self.world.bundles.init_info::<T>` must have
been called so that the BundleInfo is present in the World

# Objective
We already collect a lot of system information on startup when possible
but we don't make this information available. With the upcoming work on
a diagnostic overlay it would be useful to be able to display this
information.
## Solution
Make the already existing SystemInfo a Resource
---
## Changelog
Added `SystemInfo` Resource

# Objective
get_asset_paths tries to check whether a folder is empty, and if so
delete it. However rather than checking whether any subfolder contains
files it checks whether _all_ subfolders have files.
Also cleanup various BoxedFutures in async recursive functions like
these, rust 1.77 now allows recursive async functions (albeit still by
boxing), hurray! This is a followup to #12550 (sorta). More BoxedFuture
stuff can be removed now that rust 1.77 is out, which can use async
recursive functions! This is mainly just cleaner code wise - the
recursion still boxes the future so not much to win there.
PR is mainly whitespace changes so do disable whitespace diffs for
easier review.
# Objective
Follow up from PR #12369 to extract lighting structs from light/mod.rs
into their own file.
Part of the Purdue Refactoring Team's goals issue #12349
## Solution
- Moved PointLight from light/mod.rs to light/point_light.rs
- Moved SpotLight from light/mod.rs to light/spot_light.rs
- Moved DirectionalLight from light/mod.rs to light/directional_light.rs
# Objective
Remove color specialization from `SpritePipeline` after it became
useless in #9597
## Solution
Removed the `COLORED` flag from the pipeline key and removed the
specializing the pipeline over it.
---
## Changelog
### Removed
- `SpritePipelineKey` no longer contains the `COLORED` flag. The flag
has had no effect on how the pipeline operates for a while.
## Migration Guide
- The raw values for the `HDR`, `TONEMAP_IN_SHADER` and `DEBAND_DITHER`
flags have changed, so if you were constructing the pipeline key from
raw `u32`s you'll have to account for that.
# Objective
I was reading some of the Archetype and Bundle code and was getting
confused a little bit in some places (is the `archetype_id` in
`AddBundle` the source or the target archetype id?).
Small PR that adds some docstrings to make it easier for first-time
readers.
# Objective
* Adopted #12025 to fix merge conflicts
* In some cases we used manual impls for certain types, though they are
(at least, now) unnecessary.
## Solution
* Use macros and reflecting-by-value to avoid this clutter.
* Though there were linker issues with Reflect and the CowArc in
AssetPath (see https://github.com/bevyengine/bevy/issues/9747), I
checked these are resolved by using #[reflect_value].

# Objective
- Clarify that `ButtonInput::just_release` and
`ButtonInput::just_pressed` don't imply information about the state of
`ButtonInput::pressed` or their counterparts.
Fixes#12600
## Solution
Removed Into<AssetId<T>> for Handle<T> as proposed in Issue
conversation, fixed dependent code
## Migration guide
If you use passing Handle by value as AssetId, you should pass reference
or call .id() method on it
Before (0.13):
`assets.insert(handle, value);`
After (0.14):
`assets.insert(&handle, value);`
or
`assets.insert(handle.id(), value);`
# Objective
Fixes issue #12613 - the RNG used in examples is _deterministic_, but
its implementation is not _portable_ across platforms. We want to switch
to using a portable RNG that does not vary across platforms, to ensure
certain examples play out the same way every time.
## Solution
Replace all occurences of `rand::rngs::StdRng` with
`rand_chacha::ChaCha8Rng`, as recommended in issue #12613
---
## Changelog
- Add `rand_chacha` as a new dependency (controversial?)
- Replace all occurences of `rand::rngs::StdRng` with
`rand_chacha::ChaCha8Rng`
