# Objective
- Fixes#3531
## Solution
- Added an append wrapper to BufferVec based on the function signature
for vec.append()
---
First PR to Bevy. I didn't see any tests for other BufferVec methods
(could have missed them) and currently this method is not used anywhere
in the project. Let me know if there are tests to add or if I should
find somewhere to use append so it is not dead code. The issue mentions
implementing `truncate` and `extend` which were already implemented and
merged
[here](https://github.com/bevyengine/bevy/pull/6833/files#diff-c8fb332382379e383f1811e30c31991b1e0feb38ca436c357971755368012ced)
# Objective
- When writing render nodes that need a view, you always need to define
a `Query` on the associated view and make sure to update it manually and
query it manually. This is verbose and error prone.
## Solution
- Introduce a new `ViewNode` trait and `ViewNodeRunner` `Node` that will
take care of managing the associated view query automatically.
- The trait is currently a passthrough of the `Node` trait. So it still
has the update/run with all the same data passed in.
- The `ViewNodeRunner` is the actual node that is added to the render
graph and it contains the custom node. This is necessary because it's
the one that takes care of updating the node.
---
## Changelog
- Add `ViewNode`
- Add `ViewNodeRunner`
## Notes
Currently, this only handles the view query, but it could probably have
a ReadOnlySystemState that would also simplify querying all the readonly
resources that most render nodes currently query manually. The issue is
that I don't know how to do that without a `&mut self`.
At first, I tried making this a default feature of all `Node`, but I
kept hitting errors related to traits and generics and stuff I'm not
super comfortable with. This implementations is much simpler and keeps
the default Node behaviour so isn't a breaking change
## Reviewer Notes
The PR looks quite big, but the core of the PR is the changes in
`render_graph/node.rs`. Every other change is simply updating existing
nodes to use this new feature.
## Open questions
~~- Naming is not final, I'm opened to anything. I named it
ViewQueryNode because it's a node with a managed Query on a View.~~
~~- What to do when the query fails? All nodes using this pattern
currently just `return Ok(())` when it fails, so I chose that, but
should it be more flexible?~~
~~- Is the ViewQueryFilter actually necessary? All view queries run on
the entity that is already guaranteed to be a view. Filtering won't do
much, but maybe someone wants to control an effect with the presence of
a component instead of a flag.~~
~~- What to do with Nodes that are empty struct? Implementing
`FromWorld` is pretty verbose but not implementing it means there's 2
ways to create a `ViewNodeRunner` which seems less ideal. This is an
issue now because most node simply existed to hold the query, but now
that they don't hold the query state we are left with a bunch of empty
structs.~~
- Should we have a `RenderGraphApp::add_render_graph_view_node()`, this
isn't necessary, but it could make the code a bit shorter.

# Objective
- Support WebGPU
- alternative to #5027 that doesn't need any async / await
- fixes#8315
- Surprise fix#7318
## Solution
### For async renderer initialisation
- Update the plugin lifecycle:
- app builds the plugin
- calls `plugin.build`
- registers the plugin
- app starts the event loop
- event loop waits for `ready` of all registered plugins in the same
order
- returns `true` by default
- then call all `finish` then all `cleanup` in the same order as
registered
- then execute the schedule
In the case of the renderer, to avoid anything async:
- building the renderer plugin creates a detached task that will send
back the initialised renderer through a mutex in a resource
- `ready` will wait for the renderer to be present in the resource
- `finish` will take that renderer and place it in the expected
resources by other plugins
- other plugins (that expect the renderer to be available) `finish` are
called and they are able to set up their pipelines
- `cleanup` is called, only custom one is still for pipeline rendering
### For WebGPU support
- update the `build-wasm-example` script to support passing `--api
webgpu` that will build the example with WebGPU support
- feature for webgl2 was always enabled when building for wasm. it's now
in the default feature list and enabled on all platforms, so check for
this feature must also check that the target_arch is `wasm32`
---
## Migration Guide
- `Plugin::setup` has been renamed `Plugin::cleanup`
- `Plugin::finish` has been added, and plugins adding pipelines should
do it in this function instead of `Plugin::build`
```rust
// Before
impl Plugin for MyPlugin {
fn build(&self, app: &mut App) {
app.insert_resource::<MyResource>
.add_systems(Update, my_system);
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<RenderResourceNeedingDevice>()
.init_resource::<OtherRenderResource>();
}
}
// After
impl Plugin for MyPlugin {
fn build(&self, app: &mut App) {
app.insert_resource::<MyResource>
.add_systems(Update, my_system);
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<OtherRenderResource>();
}
fn finish(&self, app: &mut App) {
let render_app = match app.get_sub_app_mut(RenderApp) {
Ok(render_app) => render_app,
Err(_) => return,
};
render_app
.init_resource::<RenderResourceNeedingDevice>();
}
}
```
# Objective
- I want to take screenshots of examples in CI to help with validation
of changes
## Solution
- Can override how much time is updated per frame
- Can specify on which frame to take a screenshots
- Save screenshots in CI
I reused the `TimeUpdateStrategy::ManualDuration` to be able to set the
time update strategy to a fixed duration every frame. Its previous
meaning didn't make much sense to me. This change makes it possible to
have screenshots that are exactly the same across runs.
If this gets merged, I'll add visual comparison of screenshots between
runs to ensure nothing gets broken
## Migration Guide
* `TimeUpdateStrategy::ManualDuration` meaning has changed. Instead of
setting time to `Instant::now()` plus the given duration, it sets time
to last update plus the given duration.
# Objective
- Handle dangling entity references inside scenes
- Handle references to entities with generation > 0 inside scenes
- Fix a latent bug in `Parent`'s `MapEntities` implementation, which
would, if the parent was outside the scene, cause the scene to be loaded
into the new world with a parent reference potentially pointing to some
random entity in that new world.
- Fixes#4793 and addresses #7235
## Solution
- DynamicScenes now identify entities with a `Entity` instead of a u32,
therefore including generation
- `World` exposes a new `reserve_generations` function that despawns an
entity and advances its generation by some extra amount.
- `MapEntities` implementations have a new `get_or_reserve` function
available that will always return an `Entity`, establishing a new
mapping to a dead entity when the entity they are called with is not in
the `EntityMap`. Subsequent calls with that same `Entity` will return
the same newly created dead entity reference, preserving equality
semantics.
- As a result, after loading a scene containing references to dead
entities (or entities otherwise outside the scene), those references
will all point to different generations on a single entity id in the new
world.
---
## Changelog
### Changed
- In serialized scenes, entities are now identified by a u64 instead of
a u32.
- In serialized scenes, components with entity references now have those
references serialize as u64s instead of structs.
### Fixed
- Scenes containing components with entity references will now
deserialize and add to a world reliably.
## Migration Guide
- `MapEntities` implementations must change from a `&EntityMap`
parameter to a `&mut EntityMapper` parameter and can no longer return a
`Result`. Finally, they should switch from calling `EntityMap::get` to
calling `EntityMapper::get_or_reserve`.

# Objective
- Reduce compilation time
## Solution
- Make `spirv` and `glsl` shader format support optional. They are not
needed for Bevy shaders.
- on my mac (where shaders are compiled to `msl`), this reduces the
total build time by 2 to 5 seconds, improvement should be even better
with less cores
There is a big reduction in compile time for `naga`, and small
improvements on `wgpu` and `bevy_render`

# Objective
`Camera::logical_viewport_rect()` returns `Option<(Vec2, Vec2)>` which
is a tuple of vectors representing the `(min, max)` bounds of the
viewport rect. Since the function says it returns a rect and there is a
`Rect { min, max }` struct in `bevy_math`, using the struct will be
clearer.
## Solution
Replaced `Option<(Vec2, Vec2)>` with `Option<Rect>` for
`Camera::logical_viewport_rect()`.
---
## Changelog
- Changed `Camera::logical_viewport_rect` return type from `(Vec2,
Vec2)` to `Rect`
## Migration Guide
Before:
```
fn view_logical_camera_rect(camera_query: Query<&Camera>) {
let camera = camera_query.single();
let Some((min, max)) = camera.logical_viewport_rect() else { return };
dbg!(min, max);
}
```
After:
```
fn view_logical_camera_rect(camera_query: Query<&Camera>) {
let camera = camera_query.single();
let Some(Rect { min, max }) = camera.logical_viewport_rect() else { return };
dbg!(min, max);
}
```
This line does not appear to be an intended part of the `Panics`
section, but instead looks like it was missed when copy-pasting a
`Panics` section from above.
It confused me when I was reading the docs. At first I read it as if it
was an imperative statement saying not to use `match` statements which
seemed odd and out of place. Once I saw the code it was clearly in err.
# Objective
- Cleanup documentation string to reduce end-user confusion.
Links in the api docs are nice. I noticed that there were several places
where structs / functions and other things were referenced in the docs,
but weren't linked. I added the links where possible / logical.

Fixes https://github.com/bevyengine/bevy/issues/1207
# Objective
Right now, it's impossible to capture a screenshot of the entire window
without forking bevy. This is because
- The swapchain texture never has the COPY_SRC usage
- It can't be accessed without taking ownership of it
- Taking ownership of it breaks *a lot* of stuff
## Solution
- Introduce a dedicated api for taking a screenshot of a given bevy
window, and guarantee this screenshot will always match up with what
gets put on the screen.
---
## Changelog
- Added the `ScreenshotManager` resource with two functions,
`take_screenshot` and `save_screenshot_to_disk`
# Objective

# Objective
Fix#8321
## Solution
The `old_viewport_size` that is used to detect whether the viewport has
changed was not being updated and thus always `None`.
# Objective
when a mesh uses zero for all bone weights, vertices end up in the
middle of the screen.
## Solution
we can address this by explicitly setting the first bone weight to 1
when the weights are given as zero. this is the approach taken by
[unity](https://forum.unity.com/threads/whats-the-problem-with-this-import-fbx-warning.133736/)
(although that also sets the bone index to zero) and
[three.js](94c1a4b86f/src/objects/SkinnedMesh.js (L98)),
and likely other engines.
## Alternatives
it does add a bit of overhead, and users can always fix this themselves,
though it's a bit awkward particularly with gltfs.

# Objective
The clippy lint `type_complexity` is known not to play well with bevy.
It frequently triggers when writing complex queries, and taking the
lint's advice of using a type alias almost always just obfuscates the
code with no benefit. Because of this, this lint is currently ignored in
CI, but unfortunately it still shows up when viewing bevy code in an
IDE.
As someone who's made a fair amount of pull requests to this repo, I
will say that this issue has been a consistent thorn in my side. Since
bevy code is filled with spurious, ignorable warnings, it can be very
difficult to spot the *real* warnings that must be fixed -- most of the
time I just ignore all warnings, only to later find out that one of them
was real after I'm done when CI runs.
## Solution
Suppress this lint in all bevy crates. This was previously attempted in
#7050, but the review process ended up making it more complicated than
it needs to be and landed on a subpar solution.
The discussion in https://github.com/rust-lang/rust-clippy/pull/10571
explores some better long-term solutions to this problem. Since there is
no timeline on when these solutions may land, we should resolve this
issue in the meantime by locally suppressing these lints.
### Unresolved issues
Currently, these lints are not suppressed in our examples, since that
would require suppressing the lint in every single source file. They are
still ignored in CI.
# Objective
Make the coordinate systems of screen-space items (cursor position, UI,
viewports, etc.) consistent.
## Solution
Remove the weird double inversion of the cursor position's Y origin.
Once in bevy_winit to the bottom and then again in bevy_ui back to the
top.
This leaves the origin at the top left like it is in every other popular
app framework.
Update the `world_to_viewport`, `viewport_to_world`, and
`viewport_to_world_2d` methods to flip the Y origin (as they should
since the viewport coordinates were always relative to the top left).
## Migration Guide
`Window::cursor_position` now returns the position of the cursor
relative to the top left instead of the bottom left.
This now matches other screen-space coordinates like
`RelativeCursorPosition`, UI, and viewports.
The `world_to_viewport`, `viewport_to_world`, and `viewport_to_world_2d`
methods on `Camera` now return/take the viewport position relative to
the top left instead of the bottom left.
If you were using `world_to_viewport` to position a UI node the returned
`y` value should now be passed into the `top` field on `Style` instead
of the `bottom` field.
Note that this might shift the position of the UI node as it is now
anchored at the top.
If you were passing `Window::cursor_position` to `viewport_to_world` or
`viewport_to_world_2d` no change is necessary.
# Objective
- RenderGraphExt was merged, but only used in limited situations
## Solution
- Fix some remaining issues with the existing api
- Use the new api in the main pass and mass writeback
- Add CORE_2D and CORE_3D constant to make render_graph code shorter
# Objective
While working on #8299, I noticed that we're using a `capacity` field,
even though `wgpu::Buffer` exposes a `size` accessor that does the same
thing.
## Solution
Remove it from all buffer wrappers. Use `wgpu::Buffer::size` instead.
Default to 0 if no buffer has been allocated yet.
# Objective
Fixes#8284. `values` is being pushed to separately from the actual
scratch buffer in `DynamicUniformBuffer::push` and
`DynamicStorageBuffer::push`. In both types, `values` is really only
used to track the number of elements being added to the buffer, yet is
causing extra allocations, size increments and excess copies.
## Solution
Remove it and its remaining uses. Replace it with accesses to `scratch`
instead.
I removed the `len` accessor, as it may be non-trivial to compute just
from `scratch`. If this is still desirable to have, we can keep a `len`
member field to track it instead of relying on `scratch`.
# Objective
- Adding a node to the render_graph can be quite verbose and error prone
because there's a lot of moving parts to it.
## Solution
- Encapsulate this in a simple utility method
- Mostly intended for optional nodes that have specific ordering
- Requires that the `Node` impl `FromWorld`, but every internal node is
built using a new function taking a `&mut World` so it was essentially
already `FromWorld`
- Use it for the bloom, fxaa and taa, nodes.
- The main nodes don't use it because they rely more on the order of
many nodes being added
---
## Changelog
- Impl `FromWorld` for `BloomNode`, `FxaaNode` and `TaaNode`
- Added `RenderGraph::add_node_edges()`
- Added `RenderGraph::sub_graph()`
- Added `RenderGraph::sub_graph_mut()`
- Added `RenderGraphApp`, `RenderGraphApp::add_render_graph_node`,
`RenderGraphApp::add_render_graph_edges`,
`RenderGraphApp::add_render_graph_edge`
## Notes
~~This was taken out of https://github.com/bevyengine/bevy/pull/7995
because it works on it's own. Once the linked PR is done, the new
`add_node()` will be simplified a bit since the input/output params
won't be necessary.~~
This feature will be useful in most of the upcoming render nodes so it's
impact will be more relevant at that point.
Partially fixes#7985
## Future work
* Add a way to automatically label nodes or at least make it part of the
trait. This would remove one more field from the functions added in this
PR
* Use it in the main pass 2d/3d

# Objective
The type `&World` is currently in an awkward place, since it has two
meanings:
1. Read-only access to the entire world.
2. Interior mutable access to the world; immutable and/or mutable access
to certain portions of world data.
This makes `&World` difficult to reason about, and surprising to see in
function signatures if one does not know about the interior mutable
property.
The type `UnsafeWorldCell` was added in #6404, which is meant to
alleviate this confusion by adding a dedicated type for interior mutable
world access. However, much of the engine still treats `&World` as an
interior mutable-ish type. One of those places is `SystemParam`.
## Solution
Modify `SystemParam::get_param` to accept `UnsafeWorldCell` instead of
`&World`. Simplify the safety invariants, since the `UnsafeWorldCell`
type encapsulates the concept of constrained world access.
---
## Changelog
`SystemParam::get_param` now accepts an `UnsafeWorldCell` instead of
`&World`. This type provides a high-level API for unsafe interior
mutable world access.
## Migration Guide
For manual implementers of `SystemParam`: the function `get_item` now
takes `UnsafeWorldCell` instead of `&World`. To access world data, use:
* `.get_entity()`, which returns an `UnsafeEntityCell` which can be used
to access component data.
* `get_resource()` and its variants, to access resource data.
# Objective
WebP is a modern image format developed by Google that offers a
significant reduction in file size compared to other image formats such
as PNG and JPEG, while still maintaining good image quality. This makes
it particularly useful for games with large numbers of images, such as
those with high-quality textures or detailed sprites, where file size
and loading times can have a significant impact on performance.
By adding support for WebP images in Bevy, game developers using this
engine can now take advantage of this modern image format and reduce the
memory usage and loading times of their games. This improvement can
ultimately result in a better gaming experience for players.
In summary, the objective of adding WebP image format support in Bevy is
to enable game developers to use a modern image format that provides
better compression rates and smaller file sizes, resulting in faster
loading times and reduced memory usage for their games.
## Solution
To add support for WebP images in Bevy, this pull request leverages the
existing `image` crate support for WebP. This implementation is easily
integrated into the existing Bevy asset-loading system. To maintain
compatibility with existing Bevy projects, WebP image support is
disabled by default, and developers can enable it by adding a feature
flag to their project's `Cargo.toml` file. With this feature, Bevy
becomes even more versatile for game developers and provides a valuable
addition to the game engine.
---
## Changelog
- Added support for WebP image format in Bevy game engine
## Migration Guide
To enable WebP image support in your Bevy project, add the following
line to your project's Cargo.toml file:
```toml
bevy = { version = "*", features = ["webp"]}
```

# Objective
- Currently, the render graph slots are only used to pass the
view_entity around. This introduces significant boilerplate for very
little value. Instead of using slots for this, make the view_entity part
of the `RenderGraphContext`. This also means we won't need to have
`IN_VIEW` on every node and and we'll be able to use the default impl of
`Node::input()`.
## Solution
- Add `view_entity: Option<Entity>` to the `RenderGraphContext`
- Update all nodes to use this instead of entity slot input
---
## Changelog
- Add optional `view_entity` to `RenderGraphContext`
## Migration Guide
You can now get the view_entity directly from the `RenderGraphContext`.
When implementing the Node:
```rust
// 0.10
struct FooNode;
impl FooNode {
const IN_VIEW: &'static str = "view";
}
impl Node for FooNode {
fn input(&self) -> Vec<SlotInfo> {
vec![SlotInfo::new(Self::IN_VIEW, SlotType::Entity)]
}
fn run(
&self,
graph: &mut RenderGraphContext,
// ...
) -> Result<(), NodeRunError> {
let view_entity = graph.get_input_entity(Self::IN_VIEW)?;
// ...
Ok(())
}
}
// 0.11
struct FooNode;
impl Node for FooNode {
fn run(
&self,
graph: &mut RenderGraphContext,
// ...
) -> Result<(), NodeRunError> {
let view_entity = graph.view_entity();
// ...
Ok(())
}
}
```
When adding the node to the graph, you don't need to specify a slot_edge
for the view_entity.
```rust
// 0.10
let mut graph = RenderGraph::default();
graph.add_node(FooNode::NAME, node);
let input_node_id = draw_2d_graph.set_input(vec![SlotInfo::new(
graph::input::VIEW_ENTITY,
SlotType::Entity,
)]);
graph.add_slot_edge(
input_node_id,
graph::input::VIEW_ENTITY,
FooNode::NAME,
FooNode::IN_VIEW,
);
// add_node_edge ...
// 0.11
let mut graph = RenderGraph::default();
graph.add_node(FooNode::NAME, node);
// add_node_edge ...
```
## Notes
This PR paired with #8007 will help reduce a lot of annoying boilerplate
with the render nodes. Depending on which one gets merged first. It will
require a bit of clean up work to make both compatible.
I tagged this as a breaking change, because using the old system to get
the view_entity will break things because it's not a node input slot
