A little bit improvement of efficiency?

[Yuchen24]

In the function Grab(), we have

void UGrabber::Grab()
{
    // Do the line trace
    FHitResult HitResult = GetFirstPhysicsBodyInReach();
    UPrimitiveComponent* ComponentToGrab = HitResult.GetComponent();
    AActor* ActorHit = HitResult.GetActor();

    if (ActorHit != nullptr) {
	    PhysicsHandle->GrabComponent(ComponentToGrab, NAME_None, ComponentToGrab->GetOwner()->GetActorLocation(), true);
    }
}

We are retriveing both ComponentToGrab and ActorHit from HitResult, which is redundant. I think we can just get rid of ActorHit and do this

void UGrabber::Grab()
{

    // Do the line trace
    FHitResult HitResult = GetFirstPhysicsBodyInReach();
    UPrimitiveComponent* ComponentToGrab = HitResult.GetComponent();

    if (ComponentToGrab != nullptr) {
	    PhysicsHandle->GrabComponent(ComponentToGrab, NAME_None, ComponentToGrab->GetOwner()->GetActorLocation(), true);
    }

I tried it and it worked the same as it was using ActorHit.
