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"

Overlap event issue

Code snippet:

 BoxTrigger = CreateDefaultSubobject<UBoxComponent>(FName("DoorTriggerArea"));
     BoxTrigger->SetCollisionResponseToChannel(ECollisionChannel::ECC_PhysicsBody, ECollisionResponse::ECR_Overlap);
     BoxTrigger->SetCollisionResponseToChannel(ECollisionChannel::ECC_Pawn, ECollisionResponse::ECR_Overlap);
     BoxTrigger->bGenerateOverlapEvents = true;
     BoxTrigger->OnComponentBeginOverlap.AddDynamic(this, &UDoorTriggerComponent::OnBoxBeginOverlap);
     BoxTrigger->OnComponentEndOverlap.AddDynamic(this, &UDoorTriggerComponent::OnBoxEndOverlap);

 void UDoorTriggerComponent::OnBoxBeginOverlap(UPrimitiveComponent* OverlappedComp, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult)
     UE_LOG(LogTemp, Warning, TEXT("%f"), SweepResult.GetComponent()->GetMass());

The OtherComp, OverlappedComp, SweepResult.GetComponent() all point to the trigger box, not the colliding object. The events are fired normally, when i enter the collision area the even is fired but for some reason the parameters get messed up. Could anyone help me?

It seems that GetOverlappingActors works fine but i still dont understand whats wrong with the parameters.

Actually just realised this. The only overlapping component is the boxtrigger itself as anything else will be an actor. Using OtherActor works fine. Marking as solved.
