Spawn now takes a Bundle (#6054) # Objective Now that we can consolidate Bundles and Components under a single insert (thanks to #2975 and #6039), almost 100% of world spawns now look like `world.spawn().insert((Some, Tuple, Here))`. Spawning an entity without any components is an extremely uncommon pattern, so it makes sense to give spawn the "first class" ergonomic api. This consolidated api should be made consistent across all spawn apis (such as World and Commands). ## Solution All `spawn` apis (`World::spawn`, `Commands:;spawn`, `ChildBuilder::spawn`, and `WorldChildBuilder::spawn`) now accept a bundle as input: ```rust // before: commands .spawn() .insert((A, B, C)); world .spawn() .insert((A, B, C); // after commands.spawn((A, B, C)); world.spawn((A, B, C)); ``` All existing instances of `spawn_bundle` have been deprecated in favor of the new `spawn` api. A new `spawn_empty` has been added, replacing the old `spawn` api. By allowing `world.spawn(some_bundle)` to replace `world.spawn().insert(some_bundle)`, this opened the door to removing the initial entity allocation in the "empty" archetype / table done in `spawn()` (and subsequent move to the actual archetype in `.insert(some_bundle)`). This improves spawn performance by over 10%: ![image](https://user-images.githubusercontent.com/2694663/191627587-4ab2f949-4ccd-4231-80eb-80dd4d9ad6b9.png) To take this measurement, I added a new `world_spawn` benchmark. Unfortunately, optimizing `Commands::spawn` is slightly less trivial, as Commands expose the Entity id of spawned entities prior to actually spawning. Doing the optimization would (naively) require assurances that the `spawn(some_bundle)` command is applied before all other commands involving the entity (which would not necessarily be true, if memory serves). Optimizing `Commands::spawn` this way does feel possible, but it will require careful thought (and maybe some additional checks), which deserves its own PR. For now, it has the same performance characteristics of the current `Commands::spawn_bundle` on main. **Note that 99% of this PR is simple renames and refactors. The only code that needs careful scrutiny is the new `World::spawn()` impl, which is relatively straightforward, but it has some new unsafe code (which re-uses battle tested BundlerSpawner code path).** --- ## Changelog - All `spawn` apis (`World::spawn`, `Commands:;spawn`, `ChildBuilder::spawn`, and `WorldChildBuilder::spawn`) now accept a bundle as input - All instances of `spawn_bundle` have been deprecated in favor of the new `spawn` api - World and Commands now have `spawn_empty()`, which is equivalent to the old `spawn()` behavior. ## Migration Guide ```rust // Old (0.8): commands .spawn() .insert_bundle((A, B, C)); // New (0.9) commands.spawn((A, B, C)); // Old (0.8): commands.spawn_bundle((A, B, C)); // New (0.9) commands.spawn((A, B, C)); // Old (0.8): let entity = commands.spawn().id(); // New (0.9) let entity = commands.spawn_empty().id(); // Old (0.8) let entity = world.spawn().id(); // New (0.9) let entity = world.spawn_empty(); ```

Texture Atlas rework (#5103) # Objective > Old MR: #5072 > ~~Associated UI MR: #5070~~ > Adresses #1618 Unify sprite management ## Solution - Remove the `Handle<Image>` field in `TextureAtlas` which is the main cause for all the boilerplate - Remove the redundant `TextureAtlasSprite` component - Renamed `TextureAtlas` asset to `TextureAtlasLayout` ([suggestion](https://github.com/bevyengine/bevy/pull/5103#discussion_r917281844)) - Add a `TextureAtlas` component, containing the atlas layout handle and the section index The difference between this solution and #5072 is that instead of the `enum` approach is that we can more easily manipulate texture sheets without any breaking changes for classic `SpriteBundle`s (@mockersf [comment](https://github.com/bevyengine/bevy/pull/5072#issuecomment-1165836139)) Also, this approach is more *data oriented* extracting the `Handle<Image>` and avoiding complex texture atlas manipulations to retrieve the texture in both applicative and engine code. With this method, the only difference between a `SpriteBundle` and a `SpriteSheetBundle` is an **additional** component storing the atlas handle and the index. ~~This solution can be applied to `bevy_ui` as well (see #5070).~~ EDIT: I also applied this solution to Bevy UI ## Changelog - (**BREAKING**) Removed `TextureAtlasSprite` - (**BREAKING**) Renamed `TextureAtlas` to `TextureAtlasLayout` - (**BREAKING**) `SpriteSheetBundle`: - Uses a `Sprite` instead of a `TextureAtlasSprite` component - Has a `texture` field containing a `Handle<Image>` like the `SpriteBundle` - Has a new `TextureAtlas` component instead of a `Handle<TextureAtlasLayout>` - (**BREAKING**) `DynamicTextureAtlasBuilder::add_texture` takes an additional `&Handle<Image>` parameter - (**BREAKING**) `TextureAtlasLayout::from_grid` no longer takes a `Handle<Image>` parameter - (**BREAKING**) `TextureAtlasBuilder::finish` now returns a `Result<(TextureAtlasLayout, Handle<Image>), _>` - `bevy_text`: - `GlyphAtlasInfo` stores the texture `Handle<Image>` - `FontAtlas` stores the texture `Handle<Image>` - `bevy_ui`: - (**BREAKING**) Removed `UiAtlasImage` , the atlas bundle is now identical to the `ImageBundle` with an additional `TextureAtlas` ## Migration Guide * Sprites ```diff fn my_system( mut images: ResMut<Assets<Image>>, - mut atlases: ResMut<Assets<TextureAtlas>>, + mut atlases: ResMut<Assets<TextureAtlasLayout>>, asset_server: Res<AssetServer> ) { let texture_handle: asset_server.load("my_texture.png"); - let layout = TextureAtlas::from_grid(texture_handle, Vec2::new(25.0, 25.0), 5, 5, None, None); + let layout = TextureAtlasLayout::from_grid(Vec2::new(25.0, 25.0), 5, 5, None, None); let layout_handle = atlases.add(layout); commands.spawn(SpriteSheetBundle { - sprite: TextureAtlasSprite::new(0), - texture_atlas: atlas_handle, + atlas: TextureAtlas { + layout: layout_handle, + index: 0 + }, + texture: texture_handle, ..Default::default() }); } ``` * UI ```diff fn my_system( mut images: ResMut<Assets<Image>>, - mut atlases: ResMut<Assets<TextureAtlas>>, + mut atlases: ResMut<Assets<TextureAtlasLayout>>, asset_server: Res<AssetServer> ) { let texture_handle: asset_server.load("my_texture.png"); - let layout = TextureAtlas::from_grid(texture_handle, Vec2::new(25.0, 25.0), 5, 5, None, None); + let layout = TextureAtlasLayout::from_grid(Vec2::new(25.0, 25.0), 5, 5, None, None); let layout_handle = atlases.add(layout); commands.spawn(AtlasImageBundle { - texture_atlas_image: UiTextureAtlasImage { - index: 0, - flip_x: false, - flip_y: false, - }, - texture_atlas: atlas_handle, + atlas: TextureAtlas { + layout: layout_handle, + index: 0 + }, + image: UiImage { + texture: texture_handle, + flip_x: false, + flip_y: false, + }, ..Default::default() }); } ``` --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com> Co-authored-by: François <mockersf@gmail.com> Co-authored-by: IceSentry <IceSentry@users.noreply.github.com>
