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"

Calling a custom C++ function when entering a trigger box

I'm trying to call a custom function (called 'SwapCameras'), defined in a separate object (called 'CameraDirector') when the character is entering a trigger box. I hope this is clear and no code snippets are needed.

Hello,

I would suggest utilizing the OnComponentBeginOverlap function.

[h]

 //Overlap
     UFUNCTION( )
     void BeginOverlap(UPrimitiveComponent* OverlappedComponent, 
                                    AActor* OtherActor, 
                                    UPrimitiveComponent* OtherComp, 
                                    int32 OtherBodyIndex, 
                                    bool bFromSweep, 
                                    const FHitResult &SweepResult );

[cpp]

  AMyActor::AMyActor()
 {
      Collider->OnComponentBeginOverlap.AddDynamic( this, &AMyActor::BeginOverlap );
 }
 
 void AMyActor::BeginOverlap(UPrimitiveComponent* OverlappedComponent, 
                                 AActor* OtherActor, 
                                 UPrimitiveComponent* OtherComp, 
                                 int32 OtherBodyIndex, 
                                 bool bFromSweep, 
                                 const FHitResult &SweepResult )
 {
    // Call Custom Function here
 }

Thanks, Daniel
