Get component by class --> Class hierarchy (Blueprint)

[Ivan3z]

I noticed something weird when to use the
“Get component by class”.

I was trying to attach an actor to a component.

So I directly searched for a scene component (it didn’t work)

Then I tried to search for a primitive component (it didn’t work)

Finally I looked for an actor component and I cast it to scene component. (it worked)

So… i think something is wrong

what is wrong? am I?, the hierarchy?, or the function?

Thank you so much!!

You won’t be able to cast an ActorComponent to a SceneComponent, since a SceneComponent inherits from an ActorComponent.

Also, you can’t attach anything to an actor component.
You should use a SceneComponent or its descendants.

Ok, so the class diagram is correct.
The function must be wrong then. It should not fail when looking for a SceneComponent that is in fact the type of the component i were looking for with the “SocketBlue” tag.

I hope the devs fix that.

Thank you very much for your reply!!

Perhaps the actor does not have components with this tag. Sometimes developers add tags to an actor instead of a component. Check it.

Yes, it does have the tag. I am the developer, I put the tag in the component. And it works in the way that I show in the image. The problem is that the function can’t find a SceneComponent with that tag. The function thinks it is an actor component.
