Hey,
So ive got an actor that has a mesh component attached to it. (Actor1)
Ive got a second actor that also has a mesh component attached to it. (Actor2)
the second actor is spawned at runtime, and id like to attach it’s mesh component to be a child of the first actors mesh.
Ive tried the following:
Actor2->Mesh->AttachTo(Actor1->Mesh, NAME_None, EAttachLocation::SnapToTarget);
Actor2->Mesh->AttachParent = Actor1->Mesh;
And indeed inside the editor i can see that the second actor appears as a child of the first:
I.e:
Actor1
-> Actor2
However when i move Actor1’s Mesh:
Actor1->Mesh->SetWorldLocation(Somewhere);
The second actors mesh simply doesnt follow it!
Any hints?
Cheers!
Do you register new mesh component to the Actor1? I think there is function inside AActor that does the registering, Look at registering component in here
Beside, I really cant understand why you would like to attach a component of an actor to another component of an other actor, it seems a violation to philosophy of actor class.
“ActorComponents are automatically registered when the owning Actor is spawned” - Both actors are spawned in the scene, so i dont think its a registration problem (Unless you mean doing some sort of cross-registration?)
As for the cross-attaching, the tl:dr version is that its the only way i could think of doing it,
(the above is a simplified example, but basically Actor1 has 2 meshes, and there are many Actor2’s with 2 meshes each, which need to follow the appropriate mesh on Actor1)
yes they are automatically registered, but to their initiator actor, I guess you have to register them again to the new actor.(just guessing)
Have you tried
Actor2->AttachRootComponentToActor(Actor1, NULL, EAttachLocation::KeepRelativeOffset, false);
Aye, that’s what I went with the in end, ( by making the meshs on Actor1 and Actor2 be thier own actor’s with just a mesh component on it, and storing the reference via a pointer).
then that method worked perfectly, (sadly it didnt work initially as it would only attach to the root component of each actor, and i needed the cross attachment i mentioned in the other comment)
Seems a bit overengineered, but as long as it works ammiright?
Thanks for both your help, i guess it was just the wrong way of doing things!
(If you want to convert your comment to an answer ill mark it as correct)
