Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text. Here is an example: "The next event to implement is OnBecomRelevant(), and it is only fired when the Service becomes relevant"

A block of code is set as follows:

void AMyFirstAIController::OnPossess(APawn* InPawn)
{
  Super::OnPossess(InPawn);
  AUnrealAIBookCharacter* Character = Cast<AUnrealAIBookCharacter>(InPawn);
  if (Character != nullptr)
  {
    UBehaviorTree* BehaviorTree = Character->BehaviorTree;
    if (BehaviorTree != nullptr) {
      RunBehaviorTree(BehaviorTree);
    }
  }
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

void AMyFirstAIController::OnPossess(APawn* InPawn)
{
  Super::OnPossess(InPawn);
  AUnrealAIBookCharacter* Character = Cast<AUnrealAIBookCharacter>(InPawn);
  if (Character != nullptr)
  {
    UBehaviorTree* BehaviorTree = Character->BehaviorTree;
    if (BehaviorTree != nullptr) {
      RunBehaviorTree(BehaviorTree);
    }
  }
}

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select BT_MyFirstBehaviorTree from the drop-down menu within the  Behavior Tree variable."
