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"

Steps Back -1 displayed in BehaviorTree

Hello. So, I have this little problem with my Behavior Tree: It won't run when I run a simulation and Steps Back -1 is displayed in the Behavior Tree graph.

I have no clue what happened, as it just popped out of the blue. My Behavior Tree was running fine just yesterday. Furthermore, the only changes I made were to an Enumerator. The bulk of code running the Behavior Tree has remained untouched.

This is the section starting the execution of the Behavior Tree in my derived AIController Class:

 void AAI_Hero_Controller::Possess(APawn * Pawn)
 {
     Super::Possess(Pawn);
 
     AAI_Hero_Character* AIHero = Cast<AAI_Hero_Character>(Pawn);
 
     UE_LOG(LogTemp, Warning, TEXT("AI Possessed"));
     if (AIHero->BehaviorTree != nullptr && BehaviorTreeComponent != nullptr)
     {
         BlackboardComponent->InitializeBlackboard(*(AIHero->BehaviorTree->BlackboardAsset));
 
         UE_LOG(LogTemp, Warning, TEXT("Blackboard Set"));
         BehaviorTreeComponent->StartTree(*(AIHero->BehaviorTree));
         UE_LOG(LogTemp, Warning, TEXT("BT Started"));
     }
 }

Furthermore, the visual logger is not recording any activity on the timeline. Can someone please help me understand what it means? Thank you.
