Variables

  Type Name Description
Public variable UProperty Category, EditDefaultsOnly GlobalConfig float AcceptanceRadius Default AI movement's acceptance radius used to determine whether AI reached path's end
Protected variable FDelegateHandle ActorSpawnedDelegateHandle  
Protected variable UProperty Transient TArray< TObjectPtr< UAIAsyncTaskBlueprintProxy > > AllProxyObjects  
Public variable UProperty Category, EditDefaultsOnly GlobalConfig bool bAcceptPartialPaths Sets default value for rather move tasks accept partial paths or not
Public variable UProperty Category, EditDefaultsOnly GlobalConfig bool bAddBlackboardSelfKey If set to true will result in automatically adding the SelfActor key to new Blackboard assets.
Public variable UProperty Category, EditDefaultsOnly GlobalConfig bool bAllowControllersAsEQSQuerier If enable will make EQS not complaint about using Controllers as queriers.
Public variable UProperty Category, EditDefaultsOnly GlobalConfig bool bAllowStrafing Sets default value for rather move tasks allow strafing or not
Public variable UProperty Category, EditDefaultsOnly GlobalConfig bool bBlackboardKeyDecoratorAllowsNoneAsValue If enabled, blackboard based decorators will set key to 'Invalid' on creation or when selected key no longer exists (instead of using the first key of the blackboard).
Public variable UProperty Category, EditDefaultsOnly GlobalConfig bool bClearBBEntryOnBTEQSFail  
Protected variable UProperty Transient TObjectPtr< UBehaviorTreeManager > BehaviorTreeManager Behavior tree manager used by game
Public variable UProperty Category, EditDefaultsOnly GlobalConfig bool bEnableDebuggerPlugin If set, GameplayDebuggerPlugin will be loaded on module's startup
Public variable UProperty Category, EditDefaultsOnly GlobalConfig bool bFinishMoveOnGoalOverlap If true, overlapping the goal will be counted by default as finishing a move
Public variable UProperty Category, EditDefaultsOnly GlobalConfig bool bForgetStaleActors If set, actors will be forgotten by the perception system when their stimulus has expired.
Protected variable FBlackboardDataToComponentsMap BlackboardDataToComponentsMap UBlackboardComponent instances that reference the blackboard data definition
Public variable UProperty Category, EditDefaultsOnly GlobalConfig TSoftObjectPtr< UBlackboardData > DefaultBlackboard If set, new BTs will use this BB as default.
Public variable UProperty Category, EditDefaultsOnly GlobalConfig TEnumAsByte< ECollisionChannel > DefaultSightCollisionChannel Which collision channel to use for sight checks by default
Protected variable UProperty Transient TObjectPtr< UEnvQueryManager > EnvironmentQueryManager Environment query manager used by game
Protected variable UProperty Category, EditAnywhere, Meta GlobalConfig FSoftClassPath EnvQueryManagerClassName Class that will be used to spawn the env query manager, can be game-specific
Protected variable UProperty Transient TObjectPtr< UAIHotSpotManager > HotSpotManager  
Protected variable UProperty Category, EditAnywhere, Meta GlobalConfig FSoftClassPath HotSpotManagerClassName Class that will be used to spawn the hot spot manager, can be game-specific
Protected variable UProperty Transient TObjectPtr< UNavLocalGridManager > NavLocalGrids  
Public variable UProperty Category, EditDefaultsOnly GlobalConfig float PathfollowingNavLinkAcceptanceRadius Similarly to PathfollowingRegularPathPointAcceptanceRadius used by pathfollowing's internals but gets applied only when next point on a path represents a begining of navigation link
Public variable UProperty Category, EditDefaultsOnly GlobalConfig float PathfollowingRegularPathPointAcceptanceRadius Value used for pathfollowing's internal code to determine whether AI reached path's point.
Protected variable FDelegateHandle PawnBeginPlayDelegateHandle  
Protected variable UProperty Transient TObjectPtr< UAIPerceptionSystem > PerceptionSystem  
Protected variable UProperty Category, EditAnywhere, Meta GlobalConfig FSoftClassPath PerceptionSystemClassName Class that will be used to spawn the perception system, can be game-specific
