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"

OnPerceptionUpdated.AddDynamic doesn't work


i'm trying to delegate OnPerceptionUpdated to my custom function and am not able to use the AddDynamic makro.


 UPROPERTY(VisibleAnywhere, Category = "MyAIController|Perception")
 class UAIPerceptionComponent* PercComp;
 UPROPERTY(EditDefaultsOnly, Category = "MyAIController|Perception")
 class UAISenseConfig_Sight* SightCfgComp;

         void ProcessPerceivedInformation(TArray<AActor*> UpdatedActors);


 AMyAIController::AMyAIController(const FObjectInitializer& ObjectInitializer)
     PercComp = ObjectInitializer.CreateDefaultSubobject<UAIPerceptionComponent>(this, TEXT("MyPercComp"));
     SightCfgComp = ObjectInitializer.CreateDefaultSubobject<UAISenseConfig_Sight>(this, TEXT("MySightCfgComp"));
     if (PercComp && SightCfgComp) {
         SightCfgComp->SightRadius = 2000.0f;
         SightCfgComp->LoseSightRadius = 2200.0f;
         SightCfgComp->PeripheralVisionAngleDegrees = 90.0f;
         SightCfgComp->DetectionByAffiliation.bDetectEnemies = true;
         SightCfgComp->DetectionByAffiliation.bDetectFriendlies = true;
         SightCfgComp->DetectionByAffiliation.bDetectNeutrals = true;
     GetPercComp()->OnPerceptionUpdated.AddDynamic(this, &AMyAIController::ProcessPerceivedInformation);
 void AMyAIController::ProcessPerceivedInformation(TArray<AActor*> UpdatedActors) {

Does anyone spot my error ?

Hi 5v29n,

The OnPerceptionUpdated event takes a const reference to an array of actors ( const TArray<AActor*>& ), whereas your code is simply an array. If you change the parameter that should fix your compile error.
