AI Perception - Hearing problem

Im trying to extend my MyAIController with UAISenseConfig_Hearing sense, but for some reason, the Perceprion system wont use it. My setup is following:

[MyAIcontroller.h]

    ...

    MyAIController(const FObjectInitializer& ObjectInitializer = FObjectInitializer::Get());

    UAISenseConfig_Sight* sightConfig;
    UAISenseConfig_Hearing* hearingConfig;
    
    UPROPERTY(BlueprintReadOnly, Category = "Components" )
    UAIPerceptionComponent* PerceptionComp;
    ...

[MyAIcontroller.cpp]

MyAIController::MyAIController(const FObjectInitializer& ObjectInitializer)
	: Super(ObjectInitializer.SetDefaultSubobjectClass<UCrowdFollowingComponent

``(TEXT(“PathFollowingComponent”)))
{

PerceptionComp =	CreateDefaultSubobject<UAIPerceptionComponent>(TEXT("AIPerception Component"));
sightConfig =		CreateDefaultSubobject<UAISenseConfig_Sight>(TEXT("Sight Config"));	
hearingConfig =		CreateDefaultSubobject<UAISenseConfig_Hearing>(TEXT("Hearing Config"));

ConfigereSightParameters(sightConfig);
PerceptionComp->ConfigureSense(*sightConfig);

hearingConfig->DetectionByAffiliation.bDetectEnemies = true;
hearingConfig->DetectionByAffiliation.bDetectFriendlies = true;
hearingConfig->DetectionByAffiliation.bDetectNeutrals = true;

hearingConfig->HearingRange = 650;

PerceptionComp->ConfigureSense(*hearingConfig);

PerceptionComp->SetDominantSense(sightConfig->GetSenseImplementation());
	
	PerceptionComp->OnTargetPerceptionUpdated.AddDynamic(this, &MyAIController ::TargetUpdate);

}

I was using the controller for my AI for a while now(Sight was working correctly). The PerceptionComponent doesnt register the Hearing at all.

Can anyone know what could be wrong? Funny thing is, that when I create the same thing in Blueprint and just add the sense to AIPerception, it just works!

Hey SerzaNT,

You should try setting your perception component with SetPerceptionComponent(*ObjectInitializer.CreateDefaultSubobject(this, TEXT("AIPerception Component")));

And then use GetAIPerceptionComponent()->ConfigureSense(*sightConfig); in your AIController.
This will use the correct perception-comp that is also used in Blueprints.

Hope this helps :slight_smile:

Yep, that actually did the trick! Thank you!
