SimpleMoveToActor — move AI pawn toward an actor

AI MoveTo task — used in Behavior Trees via BT Task Blueprint

For Behavior Trees: use MoveToLocation/MoveToActor in Blackboard-driven tasks. Use GetBlackboardComponent().GetValueAsVector/Actor to read BB keys.

SimpleMoveToLocation — move AI pawn to a world location

Requires NavMesh in scene. Get AIController via GetController() on the pawn, cast to AIController.

MoveToLocation — AI move with full control over acceptance radius etc

Call on AIController directly. AcceptanceRadius: distance at which move is considered complete.

Pawn

An Actor that can be possessed by a Controller. Use for the player's avatar and AI agents.

Controller

Non-physical actor that possesses a Pawn and drives its input. PlayerController = human input; AIController = AI logic.

AI patrol between waypoints using NavMesh

Variables: WaypointLocations (Array<Vector>), CurrentWaypointIndex (int). Pattern: EventBeginPlay → set up WaypointLocations array → MoveToNextWaypoint (custom event). MoveToNextWaypoint: GetController → CastTo<AIController> → MoveToLocation(Dest=WaypointLocations[CurrentWaypointIndex], AcceptanceRadius=100) → Bind OnMoveCompleted delegate → In callback: Increment CurrentWaypointIndex (modulo array length) → call MoveToNextWaypoint again. Alternative: Use SimpleMoveToLocation for simpler cases. Requires NavMeshBoundsVolume in scene. GetRandomReachablePointInRadius for random wander.

Simple AI patrol between waypoints using spline or array of points

Pattern: Variables PatrolPoints(Array<Vector>), CurrentIndex(int)=0. BeginPlay: SimpleMoveToLocation(PatrolPoints[0]). OnMoveCompleted (or Tick+distance check): SET CurrentIndex = (CurrentIndex+1) % Array_Length → SimpleMoveToLocation(PatrolPoints[CurrentIndex]). Add Delay between moves for wait time. Use AIMoveTo for more control.

EnhancedInputAction — Enhanced Input system action event

K2Node_EnhancedInputAction. ActionValue type depends on InputAction (Bool, Float, Axis2D, Axis3D). Triggers: Started, Ongoing, Triggered, Completed, Canceled.

BooleanAND — logical AND

OR=BooleanOR, NOT=Not_PreBool, XOR=BooleanXOR
