it still works… but…
I have some errors here, on the “GrabComponentAtLocationWithRotation” function (third and fourth parameters), the thing is it shows this “error” on ComponentToGrab even if i declared as a UPrimitiveComponent.

if (ActorHit)
	{
		PhysicsHandle->GrabComponentAtLocationWithRotation(
			ComponentToGrab,
			NAME_None,
			ComponentToGrab->GetOwner()->GetActorLocation(),
			ComponentToGrab->GetOwner()->GetActorRotation());
	}

It works for me on UE 4.19.1:
#include “Components/PrimitiveComponent.h”
