Animatable trait for interpolation and blending

8

# Objective Allow animation of types other than translation, scale, and rotation on `Transforms`. ## Solution Add a base trait for all values that can be animated by the animation...

Avoid unnecessary copying with BufferVec::swap

2

# Objective `prepare_skinned_meshes` is repeatedly copying values from `ExtractedJoints` when both end up identical to each other and cleared every frame. ## Solution - Add spans for measuring the time...

Replace BlobVec's swap_scratch with a swap_nonoverlapping

19

# Objective BlobVec currently relies on a scratch piece of memory allocated at initialization to make a temporary copy of a component when using `swap_remove_and_{forget/drop}`. This is potentially suboptimal as...

Change Archetype::entity_table_rows to u32

3

# Objective A follow-up to #4723. Both archetypes and tables cannot store more than u32::MAX rows, as there can only be u32::MAX entities alive at any given time, so store...

Parallelized transform propagation

Recompute Aabbs for updated Meshes

1

# Objective Partially address #4294. This was attempted in #4944 and #5423., but reverted in #5489. `Aabb` components are not updated when the underlying `Mesh` has changed in some way....

Propagate transforms in fixed update

3

# Objective Fix #7836. `GlobalTransform` is not updated in `FixedUpdate`. ## Solution Add it to `FixedUpdate`, keep the same system sets, clean up the code a bit. --- ## Changelog...

Current UiStack based extraction potentially leads to poor batching

3

## Bevy version a3baf2ae869611a84cf1bc062c498ea08128cbd9 ## What you did `cargo run --profile stress-test --features trace_tracy --example many_buttons` ## What went wrong Issuing 24,000+ draw calls when it could be issuing 3....
