Question [1.0.0-exp.8] Baker remove component and destroy entity

At 1.0 release, how can I remove redundant components in Baker since there's no remove component and destroy entity API anymore?

 

It's a 2 part process. Bake then execute on baked data.
You need to do this in the second part via an ISystem (or SystemBase)

Code (CSharp):

1. [WorldSystemFilter(WorldSystemFilterFlags.BakingSystem)]
2. internal partial struct YourSystem : ISystem

There's also an attribute, [TemporaryBakingType], that can be used to pass data between Baker and your Systems that will be removed at the end and not make runtime

So you can create a

Code (CSharp):

1.  
2. [TemporaryBakingType]
3. struct NoTranslation: IComponentData {}
4.  
5. public class NoTranslationAuthoring : MonoBehaviour {}
6.  
7. public class NoTranslationBaker : Baker<NoTranslationAuthoring>
8. {
9.     public override void Bake(NoTranslationAuthoring authoring)
10.     {
11.         AddComponent<NoTranslation>();
12.     }
13. }
14.  
15. [WorldSystemFilter(WorldSystemFilterFlags.BakingSystem)]
16. public partial struct NoTranslationSystem : ISystem {
17.     public void OnUpdate(ref SystemState state)
18.     {
19.         var ecb = new EntityCommandBuffer(Allocator.Temp);
20.         foreach (var (_, entity) in SystemAPI.Query<NoTranslation>().WithEntityAccess())
21.         {
22.             ecb.RemoveComponent<Translation>(entity);
23.         }
24.         ecb.Playback(state.EntityManager);
25.     }
26.  
27.     // ...
28. }

I'm using the code you have above, but using it to remove the Parent components that Unity adds. The system runs, but the foreach section doesn't, even though I can see Entities with the RemoveParent BakingType component I added.

It looks like instead of this, I'd also be able to add a BakingOnlyEntity component to the parent entity (which is just an empty GameObject in the subscene used for grouping), but that component doesn't seem to exist in my Entities package.
