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"

Trigger Volume code crashing on Play

Just following a tutorial on volume triggers, the game started crashing when I press play I narrowed it down to this if statement in OpenDoor.cpp:

 void UOpenDoor::TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction)
 {
     Super::TickComponent(DeltaTime, TickType, ThisTickFunction);
     
     // Poll Door every frame, if actor enters trigger volume OpenDoor() 
     if (PressurePlate->IsOverlappingActor(ActorThatOpens))
         //THIS IF IS CAUSING THE CRASH[link text][1]
     {
     OpenDoor();
     }
 }


OpenDoor.h for reference:

 {
     GENERATED_BODY()
 
 public:    
     // Sets default values for this component's properties
     UOpenDoor();
 
     UPROPERTY(EditAnywhere)
     class    ATriggerVolume *PressurePlate;
 
     UPROPERTY(EditAnywhere)
     class     AACtor *ActorThatOpens;
     
     protected:
     // Called when the game starts
     virtual void BeginPlay() override;
 
     void OpenDoor();
 
 public:    
     // Called every frame
     virtual void TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction) override;
 
 
 };
