Set the position of an AActor relative to an other AActor

Thank you very muche for your fast answer. Yes, I tried it. And you are right, this attaches the actor to the other actor.
Unfortunately dose this do not have any effect to the mesh. How can I bind the mesh to the actors component?

I use for the “attacher”:

    if(overlappingObjects.Num()>1){
        AActor* BasicObject = overlappingObjects[0];
        for(AActor* A:overlappingObjects){
            if(BasicObject!= A){
                
                A->AttachToActor(BasicObject,FAttachmentTransformRules(EAttachmentRule::KeepWorld, true));
                 
            }
        }
    }

And for the other object:

AStoneBrick::AStoneBrick()
{
 	// Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
	PrimaryActorTick.bCanEverTick = true;

    this->Scene = CreateDefaultSubobject<USceneComponent>(TEXT("Scene"));
    this->RootComponent = Scene;

    this->ObjectMesh = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("Mesh"));
    this->ObjectMesh->AttachTo(RootComponent);
    this->ObjectMesh->SetSimulatePhysics(true);
    this->ObjectMesh->SetNotifyRigidBodyCollision(true);

}

**what am I doing wrong? **
Thank you very muche!
