Unreal Objects owned by Actors in a

[carmine pivot]

Hey Dan! I'm continuing this because I made some tests and I don't manage to make it work like you suggested.
As you suggested, I created an object reference to my component (PersistentAmbComponent in this case) in a GameInstance class. However, on level change, I still have OnComponentDestroyed that gets called. What am I missing/not seeing?
(and if you feel this discussion is best had somewhere else, don't hesitate to tell me!) 😄 Thanks a lot for your help ❤️

What is the super class of UPersistentAmbientComponent? is it a regular uobject?

Are those Blueprints in an Actor class?

BTW looking at the code for audio component persistance it seems you can just create a persistent audio component -

though it's still a USceneComponent so will probably get garbage collected if it's not a reference somewhere (you can also try AttachToRoot() to make it not garbage collectable until you release it, probably)

UActorComponent

Yes!

Indeed, that's what I'm trying to understand and replicate to other components 😄

I think a UActorComponent will be owned by its actor, which will always belong to a world and can't persist between levels.

But UAudioComponent is also a UActorComponent

[thorn wadi]

Even though now that I look at it USceneComponent is derived from UActorComponent so UAudioComponent is also an actor component. but still, might be worth trying for a UObject

Garbage Collection will attempt to destroy child objects. Only a strong pointer with a UPROPERTY macro will prevent its destruction.

TObjectPtr

But it's easier if you can assign the persistent object to be its owner.
