How to override a parent component in UE4 C++?

@Tomza

//This doesn’t work for B

child1->Box (the component is inherited from A, not created in B)->AttachToComponent(GetMesh(), FAttachmentTransformRules::SnapToTargetNotIncludingScale, SocketName);

child2->Box (the component is inherited from A, not created in B)->AttachToComponent(GetMesh(), FAttachmentTransformRules::SnapToTargetNotIncludingScale, SocketName);

, but it works for A:

parent->Box (the component is created in A)->AttachToComponent(GetMesh(), FAttachmentTransformRules::SnapToTargetNotIncludingScale, SocketName);

What do you mean saying “doesn’t work”?
And if Box is member of class A, then you don’t need downcasting to B1/B2/B3, etc. to access this var.
