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"

One AIController for multiple BT and BB

I have following AIController.

 AEnemyAIController::AEnemyAIController()
 {
     Blackboard = CreateDefaultSubobject<UBlackboardComponent>(TEXT("Blackboard"));
     BehaviorTree = CreateDefaultSubobject<UBehaviorTreeComponent>(TEXT("BehaviorTreeComponent"));

     PerceptionComponent = CreateDefaultSubobject<UAIPerceptionComponent>(TEXT("PerceptionComponent"));
     PerceptionComponent->OnPerceptionUpdated.AddDynamic(this, &AEnemyAIController::OnPerceptionUpdated);

     UAISenseConfig_Sight* SightConfig = CreateDefaultSubobject<UAISenseConfig_Sight>(TEXT("AISightConfig"));
     SightConfig->SightRadius = 500;
     SightConfig->LoseSightRadius = 550;
     SightConfig->PeripheralVisionAngleDegrees = 90.f;
     SightConfig->DetectionByAffiliation.bDetectEnemies = true;
     SightConfig->DetectionByAffiliation.bDetectNeutrals = false;
     SightConfig->DetectionByAffiliation.bDetectFriendlies = false;

     PerceptionComponent->ConfigureSense(*SightConfig);

     SetGenericTeamId(FGenericTeamId(1));
 }

 void AEnemyAIController::Possess(APawn* InPawn)
 {
     Super::Possess(InPawn);

     AEnemyCharacter* EnemyCharacter = Cast<AEnemyCharacter>(InPawn);
     if (EnemyCharacter != nullptr && EnemyCharacter->BehaviorTree != nullptr)
     {
         Blackboard->InitializeBlackboard(*EnemyCharacter->BehaviorTree->BlackboardAsset);
         EnemyKeyID = Blackboard->GetKeyID("Target");

         FBlackboard::FKey HomeLocationKey = Blackboard->GetKeyID("HomeLocation");
         Blackboard->SetValue<UBlackboardKeyType_Vector>(HomeLocationKey, InPawn->GetActorLocation());

         BehaviorTree->StartTree(*EnemyCharacter->BehaviorTree);
     }
 }

For some reason blackboard instance is not unique and HomeLocation variable is the same for all enemies and equal to last enemy. As I understand I need to have unique blackboard for each enemy character. How to organize this better, I mean "in UE way".
