Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

FHitResult ImpactPoint returns sweep start

I'm trying to get the distance from an actor to the closest collider using the following code, however Hit.ImpactPoint always returns the same as GetActorLocation(). This also happens with SweepMulti. How can I get the collision point, or is there another way to get the distance?

 FHitResult Hit;
 FVector Location = GetActorLocation();
 float Radius = 50;
 if (GetWorld()->SweepSingle(Hit, Location, Location + FVector(0, 0, Radius), FQuat::Identity, FCollisionShape::MakeSphere(Radius), FCollisionQueryParams(FName("Outline"), false, this), FCollisionObjectQueryParams()))
 {
     GEngine->AddOnScreenDebugMessage(-1, 15, FColor::Blue, Location.ToString() + " - " + Hit.ImpactPoint.ToString());
 }

You are probably hitting the actor doing the sweep. Make sure to add it to the Ignored Actors list.

 FCollisionQueryParams queryParams;
 queryParams.AddIgnoredActor(this);

Thanks, but I'm still getting the same problem. Also I should have said the actor doing the sweep doesn't have any collision.
