Resolved Are Entities including Component "Prefab" automatically excluded from queries?

I have a component with the name "EntityNameComponent", which will be attached to certain entities via authoring (baker).

A system named "SetEntityNameSystem" is doing a query over these components and it shows 0 Entities. This makes sense, since this system removes the component from the entity again.


But at the same time, if I do a Component Query via Inspector, it tells me that there are 38 Entities.
(Worth noting: All of these entities have the component (tag) "Prefab" attached to them)


I mean, it makes sense that in most cases I don't want to query the prefab entities, but it makes the inspection confusing. Imho there should be "Prefab" listed as excluded. Also, what if I want to query the prefab entities? It feels like I don't have control over my entities..

 

Inspector is correct. Systems ignores prefabs by default. But you have multiple entities with given components.

Yes, prefab entities are excluded from usual jobs queries. Unless you specify otherwise.

In the end, you usally don't want move, rotate or manipulate on prefabs. Unless during prefabs creation. Consider for example projectile prefab, where you spawn tons of projectiles none stop, during gameplay.

You may want to include specifically prefab component in a query. This way you filter them specifically. Also, you can cache prefabs references in a singleton, or some other collection, if you wish.

 

Thanks for the confirmation!
But then I think they should display it in a better way -making it clear that both are indeed "not" the same query, the other one just hides a default exclude.

Like you said I usually have prefabs references in a singleton, but still good to know, thx

 

EntityQueryBuilder also has .WithOptions(EntityQueryOptions.IncludePrefab) to include such entities.
