Add core and alloc over std Lints (#15281)
# Objective - Fixes #6370 - Closes #6581 ## Solution - Added the following lints to the workspace: - `std_instead_of_core` - `std_instead_of_alloc` - `alloc_instead_of_core` - Used `cargo +nightly fmt` with [item level use formatting](https://rust-lang.github.io/rustfmt/?version=v1.6.0&search=#Item%5C%3A) to split all `use` statements into single items. - Used `cargo clippy --workspace --all-targets --all-features --fix --allow-dirty` to _attempt_ to resolve the new linting issues, and intervened where the lint was unable to resolve the issue automatically (usually due to needing an `extern crate alloc;` statement in a crate root). - Manually removed certain uses of `std` where negative feature gating prevented `--all-features` from finding the offending uses. - Used `cargo +nightly fmt` with [crate level use formatting](https://rust-lang.github.io/rustfmt/?version=v1.6.0&search=#Crate%5C%3A) to re-merge all `use` statements matching Bevy's previous styling. - Manually fixed cases where the `fmt` tool could not re-merge `use` statements due to conditional compilation attributes. ## Testing - Ran CI locally ## Migration Guide The MSRV is now 1.81. Please update to this version or higher. ## Notes - This is a _massive_ change to try and push through, which is why I've outlined the semi-automatic steps I used to create this PR, in case this fails and someone else tries again in the future. - Making this change has no impact on user code, but does mean Bevy contributors will be warned to use `core` and `alloc` instead of `std` where possible. - This lint is a critical first step towards investigating `no_std` options for Bevy. --------- Co-authored-by: François Mockers <francois.mockers@vleue.com> |

Refactor App and SubApp internals for better separation (#9202)
# Objective This is a necessary precursor to #9122 (this was split from that PR to reduce the amount of code to review all at once). Moving `!Send` resource ownership to `App` will make it unambiguously `!Send`. `SubApp` must be `Send`, so it can't wrap `App`. ## Solution Refactor `App` and `SubApp` to not have a recursive relationship. Since `SubApp` no longer wraps `App`, once `!Send` resources are moved out of `World` and into `App`, `SubApp` will become unambiguously `Send`. There could be less code duplication between `App` and `SubApp`, but that would break `App` method chaining. ## Changelog - `SubApp` no longer wraps `App`. - `App` fields are no longer publicly accessible. - `App` can no longer be converted into a `SubApp`. - Various methods now return references to a `SubApp` instead of an `App`. ## Migration Guide - To construct a sub-app, use `SubApp::new()`. `App` can no longer convert into `SubApp`. - If you implemented a trait for `App`, you may want to implement it for `SubApp` as well. - If you're accessing `app.world` directly, you now have to use `app.world()` and `app.world_mut()`. - `App::sub_app` now returns `&SubApp`. - `App::sub_app_mut` now returns `&mut SubApp`. - `App::get_sub_app` now returns `Option<&SubApp>.` - `App::get_sub_app_mut` now returns `Option<&mut SubApp>.` |

Reorder render sets, refactor bevy_sprite to take advantage (#9236)
This is a continuation of this PR: #8062 # Objective - Reorder render schedule sets to allow data preparation when phase item order is known to support improved batching - Part of the batching/instancing etc plan from here: https://github.com/bevyengine/bevy/issues/89#issuecomment-1379249074 - The original idea came from @inodentry and proved to be a good one. Thanks! - Refactor `bevy_sprite` and `bevy_ui` to take advantage of the new ordering ## Solution - Move `Prepare` and `PrepareFlush` after `PhaseSortFlush` - Add a `PrepareAssets` set that runs in parallel with other systems and sets in the render schedule. - Put prepare_assets systems in the `PrepareAssets` set - If explicit dependencies are needed on Mesh or Material RenderAssets then depend on the appropriate system. - Add `ManageViews` and `ManageViewsFlush` sets between `ExtractCommands` and Queue - Move `queue_mesh*_bind_group` to the Prepare stage - Rename them to `prepare_` - Put systems that prepare resources (buffers, textures, etc.) into a `PrepareResources` set inside `Prepare` - Put the `prepare_..._bind_group` systems into a `PrepareBindGroup` set after `PrepareResources` - Move `prepare_lights` to the `ManageViews` set - `prepare_lights` creates views and this must happen before `Queue` - This system needs refactoring to stop handling all responsibilities - Gather lights, sort, and create shadow map views. Store sorted light entities in a resource - Remove `BatchedPhaseItem` - Replace `batch_range` with `batch_size` representing how many items to skip after rendering the item or to skip the item entirely if `batch_size` is 0. - `queue_sprites` has been split into `queue_sprites` for queueing phase items and `prepare_sprites` for batching after the `PhaseSort` - `PhaseItem`s are still inserted in `queue_sprites` - After sorting adjacent compatible sprite phase items are accumulated into `SpriteBatch` components on the first entity of each batch, containing a range of vertex indices. The associated `PhaseItem`'s `batch_size` is updated appropriately. - `SpriteBatch` items are then drawn skipping over the other items in the batch based on the value in `batch_size` - A very similar refactor was performed on `bevy_ui` --- ## Changelog Changed: - Reordered and reworked render app schedule sets. The main change is that data is extracted, queued, sorted, and then prepared when the order of data is known. - Refactor `bevy_sprite` and `bevy_ui` to take advantage of the reordering. ## Migration Guide - Assets such as materials and meshes should now be created in `PrepareAssets` e.g. `prepare_assets<Mesh>` - Queueing entities to `RenderPhase`s continues to be done in `Queue` e.g. `queue_sprites` - Preparing resources (textures, buffers, etc.) should now be done in `PrepareResources`, e.g. `prepare_prepass_textures`, `prepare_mesh_uniforms` - Prepare bind groups should now be done in `PrepareBindGroups` e.g. `prepare_mesh_bind_group` - Any batching or instancing can now be done in `Prepare` where the order of the phase items is known e.g. `prepare_sprites` ## Next Steps - Introduce some generic mechanism to ensure items that can be batched are grouped in the phase item order, currently you could easily have `[sprite at z 0, mesh at z 0, sprite at z 0]` preventing batching. - Investigate improved orderings for building the MeshUniform buffer - Implementing batching across the rest of bevy --------- Co-authored-by: Robert Swain <robert.swain@gmail.com> Co-authored-by: robtfm <50659922+robtfm@users.noreply.github.com> |

Use GpuArrayBuffer for MeshUniform (#9254)
# Objective
- Reduce the number of rebindings to enable batching of draw commands
## Solution
- Use the new `GpuArrayBuffer` for `MeshUniform` data to store all
`MeshUniform` data in arrays within fewer bindings
- Sort opaque/alpha mask prepass, opaque/alpha mask main, and shadow
phases also by the batch per-object data binding dynamic offset to
improve performance on WebGL2.
---
## Changelog
- Changed: Per-object `MeshUniform` data is now managed by
`GpuArrayBuffer` as arrays in buffers that need to be indexed into.
## Migration Guide
Accessing the `model` member of an individual mesh object's shader
`Mesh` struct the old way where each `MeshUniform` was stored at its own
dynamic offset:
```rust
struct Vertex {
@location(0) position: vec3<f32>,
};
fn vertex(vertex: Vertex) -> VertexOutput {
var out: VertexOutput;
out.clip_position = mesh_position_local_to_clip(
mesh.model,
vec4<f32>(vertex.position, 1.0)
);
return out;
}
```
The new way where one needs to index into the array of `Mesh`es for the
batch:
```rust
struct Vertex {
@builtin(instance_index) instance_index: u32,
@location(0) position: vec3<f32>,
};
fn vertex(vertex: Vertex) -> VertexOutput {
var out: VertexOutput;
out.clip_position = mesh_position_local_to_clip(
mesh[vertex.instance_index].model,
vec4<f32>(vertex.position, 1.0)
);
return out;
}
```
Note that using the instance_index is the default way to pass the
per-object index into the shader, but if you wish to do custom rendering
approaches you can pass it in however you like.

Add GpuArrayBuffer and BatchedUniformBuffer (#8204)
# Objective - Add a type for uploading a Rust `Vec<T>` to a GPU `array<T>`. - Makes progress towards https://github.com/bevyengine/bevy/issues/89. ## Solution - Port @superdump's `BatchedUniformBuffer` to bevy main, as a fallback for WebGL2, which doesn't support storage buffers. - Rather than getting an `array<T>` in a shader, you get an `array<T, N>`, and have to rebind every N elements via dynamic offsets. - Add `GpuArrayBuffer` to abstract over `StorageBuffer<Vec<T>>`/`BatchedUniformBuffer`. ## Future Work Add a shader macro kinda thing to abstract over the following automatically: https://github.com/bevyengine/bevy/pull/8204#pullrequestreview-1396911727 --- ## Changelog * Added `GpuArrayBuffer`, `GpuComponentArrayBufferPlugin`, `GpuArrayBufferable`, and `GpuArrayBufferIndex` types. * Added `DynamicUniformBuffer::new_with_alignment()`. --------- Co-authored-by: Robert Swain <robert.swain@gmail.com> Co-authored-by: François <mockersf@gmail.com> Co-authored-by: Teodor Tanasoaia <28601907+teoxoy@users.noreply.github.com> Co-authored-by: IceSentry <IceSentry@users.noreply.github.com> Co-authored-by: Vincent <9408210+konsolas@users.noreply.github.com> Co-authored-by: robtfm <50659922+robtfm@users.noreply.github.com> |
