François c6958b3056 add a SceneBundle to spawn a scene (#2424) ... # Objective - Spawning a scene is handled as a special case with a command `spawn_scene` that takes an handle but doesn't let you specify anything else. This is the only handle that works that way. - Workaround for this have been to add the `spawn_scene` on `ChildBuilder` to be able to specify transform of parent, or to make the `SceneSpawner` available to be able to select entities from a scene by their instance id ## Solution Add a bundle ```rust pub struct SceneBundle { pub scene: Handle<Scene>, pub transform: Transform, pub global_transform: GlobalTransform, pub instance_id: Option<InstanceId>, } ``` and instead of ```rust commands.spawn_scene(asset_server.load("models/FlightHelmet/FlightHelmet.gltf#Scene0")); ``` you can do ```rust commands.spawn_bundle(SceneBundle { scene: asset_server.load("models/FlightHelmet/FlightHelmet.gltf#Scene0"), ..Default::default() }); ``` The scene will be spawned as a child of the entity with the `SceneBundle` ~I would like to remove the command `spawn_scene` in favor of this bundle but didn't do it yet to get feedback first~ Co-authored-by: François <8672791+mockersf@users.noreply.github.com> Co-authored-by: Carter Anderson <mcanders1@gmail.com>		2022-06-09 20:34:09 +00:00
