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"

Why are USphereComponent InitSphereRadius and SetSphereRadius not changing the radius of my USphere component?

I have a pawn class written in C++ that has a USphereComponent attached to it like so:

MYCLASSNAME.h

    class MYPROJECT_API AMYCLASSNAME : public APawn{
          UPROPERTY(BlueprintReadWrite)
          USphereComponent* SecondarySphere;
     }

MYCLASSNAME.cpp

 // Constructor
 AMYCLASSNAME::AMYCLASSNAME()
 {
      // Set this pawn to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
     PrimaryActorTick.bCanEverTick = true;
 
     SecondarySphere = CreateDefaultSubobject<USphereComponent>(TEXT("SecondarySphere"));
     SecondarySphere->InitSphereRadius(3000.0f);
     SecondarySphere->SetSphereRadius(300000.0f);
     SecondarySphere->SetupAttachment(RootComponent);
     SecondarySphere->OnComponentBeginOverlap.AddDynamic(this, &AMYCLASSNAME::OnSphereComponentOverlap);
     SecondarySphere->OnComponentEndOverlap.AddDynamic(this, &AMYCLASSNAME::OnEndSphereComponentOverlap);
 }

I've played around with a couple of different values for InitSphereRadius, and SetSphereRadius, but neither of them appear to alter the size of the inherited component (on a blueprint child of AMYCLASSNAME). I'm sure I'm missing something simple, but I'm not sure what. Detailed explanations of "why" are appreciated as well as any ideas on how I should troubleshoot this problem.

Try attaching it to a scene component or make it the root component of the actor before calling SetSphereRadius()
