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"

Converting source files from previous versions

Dear UE4 Community,

I'm trying to convert a header and cpp file syntax from an older version to 4.9, Can you please help me? Thanks. Iknow that USphereComponent is now declared as a pointer, but can't figure out the rest, thanks again.

Header File

 class GOLDENEGG_API ANPC : public ACharacter
   // This is the NPC's message that he has to tell us.
   UPROPERTY(EditAnywhere, BlueprintReadWrite, Category =   
   FString NpcMessage;
   // The sphere that the player can collide with to get item
   UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category =   
   TSubobjectPtr<class USphereComponent> ProxSphere;
   // The corresponding body of this function is 
   // ANPC::Prox_Implementation, __not__ ANPC::Prox()!
   // This is a bit weird and not what you'd expect,
   // but it happens because this is a BlueprintNativeEvent
   UFUNCTION(BlueprintNativeEvent, Category = "Collision")
   void Prox( AActor* OtherActor, UPrimitiveComponent* OtherComp,   
   int32 OtherBodyIndex, bool bFromSweep, const FHitResult &   
   SweepResult );



 ANPC::ANPC(const class FPostConstructInitializeProperties& PCIP) : 
   ProxSphere = PCIP.CreateDefaultSubobject<USphereComponent>(this,   
   TEXT("Proximity Sphere"));
   ProxSphere->AttachTo( RootComponent );
   ProxSphere->SetSphereRadius( 32.f );
   // Code to make ANPC::Prox() run when this proximity sphere
   // overlaps another actor.
   ProxSphere->OnComponentBeginOverlap.AddDynamic( this,   
   &ANPC::Prox );
   NpcMessage = "Hi, I'm Owen";//default message, can be edited
   // in blueprints

Product Version: UE 4.9

Does it build? If it builds and you don't have any warnings (In UE4 before something is removed or changed it's depricated and shows warning during compilation) then everything is ok
