Variables

  Type Name Description
Public variable UProperty Category, EditAnywhere BlueprintReadWrite Transient TArray< TObjectPtr< UBlackboardKeyType > > AllowedTypes Array of allowed types with additional properties (e.g. uobject's base class) EditAnywhere is required for FBlackboardSelectorDetails::CacheBlackboardData()
Protected variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite uint32: 1 bNoneIsAllowedValue Requires BlueprintReadWrite so that blueprint creators (using MakeBlackboardKeySelector) can specify whether or not None is Allowed.

Public variable UProperty Category BlueprintReadWrite editinstanceonly FName SelectedKeyName Name of selected key
Public variable UProperty Category BlueprintReadWrite Transient editinstanceonly TSubclassOf< UBlackboardKeyType > SelectedKeyType Class of selected key
