UE crashes when pressing Play

[Kevin_DB]

Hello,

Whenever I add UE_LOG(LogTemp, Warning, TEXT("Target: %s"), *ActorName) and press play UE4 stops working, crashes and I have to restart.

It does compile properly, it builds properly, …

I have the following code:

FHitResult Hit;
FCollisionQueryParams TraceParams(FName(TEXT("")), false, GetOwner());
// Line-trace (ray-cast) to reach distance
bool IsHit = GetWorld()->LineTraceSingleByObjectType(
	OUT Hit,
	PlayerLocation,
	LineTraceEnd,
	FCollisionObjectQueryParams(ECollisionChannel::ECC_PhysicsBody),
	TraceParams
);

// see what we hit

if (IsHit)
{
	FString ActorName = Hit.GetActor()->GetName();
	UE_LOG(LogTemp, Warning, TEXT("Target: %s"), *ActorName)
}

Solved:

Why won't this method work?

Hit.GetActor() might return nullptr, so you should check that before accessing any of it's methods If(Hit.GetActor()) { UE_LOG(LogTemp, Warning, TEXT("%s"), *Hit.GetActor()->GetName()) }

Hit.GetActor() might return nullptr, so you should check that before accessing any of it’s methods If(Hit.GetActor()) { UE_LOG(LogTemp, Warning, TEXT("%s"), *Hit.GetActor()->GetName()) }

I had the same problem, thanks for the fix!!
Really appreciate it!
