# Objective
Closes#9955.
Use the same interface for all "pure" builder types: taking and
returning `Self` (and not `&mut Self`).
## Solution
Changed `DynamicSceneBuilder`, `SceneFilter` and `TableBuilder` to take
and return `Self`.
## Changelog
### Changed
- `DynamicSceneBuilder` and `SceneBuilder` methods in `bevy_ecs` now
take and return `Self`.
## Migration guide
When using `bevy_ecs::DynamicSceneBuilder` and `bevy_ecs::SceneBuilder`,
instead of binding the builder to a variable, directly use it. Methods
on those types now consume `Self`, so you will need to re-bind the
builder if you don't `build` it immediately.
Before:
```rust
let mut scene_builder = DynamicSceneBuilder::from_world(&world);
let scene = scene_builder.extract_entity(a).extract_entity(b).build();
```
After:
```rust
let scene = DynamicSceneBuilder::from_world(&world)
.extract_entity(a)
.extract_entity(b)
.build();
```
