Question Alternative to Entities.WithStoreEntityQueryInField() for ISystem?

With the old Entities.ForEach-way of scheduling jobs it was possible to access the EntityQuery that's being used for the job through .WithStoreEntityQueryInField().

Is there something comparable that works with ISystem?
Looking into the generated code for an ISystem I can see the queries are all there, but I can't find a way to access them.

 

Something like this ?

Code (CSharp):

1.     public void OnUpdate(ref SystemState state)
2.     {
3.         foreach (var (go,entity) in SystemAPI.Query<GameObjectRepresentation>().WithEntityAccess())
4.         {
5.             GameObject.Instantiate(go.Prefab);
6.             Debug.Log($"Instanciating GameObject representation of entity {entity}");
7.         }      
8.     }

 

Not quite, the point of WithStoreEntityQueryInField is that you don't have to manually write the EntityQuery yourself.
Of course if you write a main thread foreach loop like in your example you have to do it, but when scheduling a job the query for it already gets generated automatically. The question is just if there is a way to access that query (like we had with Entities.ForEach) or not.

 

Nope. Idiomatic foreach API doesn't support that yet.

 

Sorry, I'm not explaining it very well, but I'm not looking for something that has anything to do with idiomatic foreach.
I need to access the EntityQuery that is generated when scheduling a job (i.e. IJobEntity), but I guess that's just not possible yet.

 

How about building the query yourself? I'm not sure, though, if this is allowed in ISystem. This is pretty much our go to with normal class systems.

 

The same valid for IJobEntity - this API doesn't support that. Your best bet in that case (as described above), at least for now, is build your query and use if for schedule IJobEntity (for idiomatic foreach API you still can't use that as it's not a job)
