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.

Elevator or moving platform with timeline and trigger

Pattern: Variables StartLocation(Vector), EndLocation(Vector). BeginPlay: SET StartLocation=GetActorLocation. Timeline MoveTimeline(Alpha 0→1 over Duration). Trigger overlap/button press → Play Timeline. Timeline Update: VLerp(StartLocation, EndLocation, Alpha) → SetActorLocation(Self, Result, bSweep=true). Finished: Delay → Reverse Timeline.

MoveToLocation — AI move with full control over acceptance radius etc

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

K2_TeleportTo — teleport actor to new location and rotation

K2_TeleportTo.

K2_SetActorLocation — set actor world position with sweep and teleport

Internal UE5 name is K2_SetActorLocation. FindFunctionByName must use K2_ prefix.

AddActorLocalOffset — move actor by local-space delta

DeltaLocation is in ACTOR local space, not world space.

AddActorWorldOffset — move actor by world-space delta

GetCharacterMovement — get character movement component

ACharacter method. Returns UCharacterMovementComponent.

Sprint system with stamina drain and recovery

Pattern: Variables bIsSprinting(bool), Stamina(float)=100, MaxStamina(float)=100, SprintSpeed(float)=1200, WalkSpeed(float)=600, DrainRate(float)=20, RecoverRate(float)=10. Sprint pressed: bIsSprinting=true → SetMaxWalkSpeed(SprintSpeed). Released: bIsSprinting=false → SetMaxWalkSpeed(WalkSpeed). Tick: Branch(bIsSprinting) → Stamina -= DrainRate*DT. Else: Stamina += RecoverRate*DT. Clamp(0, Max). If Stamina<=0 → force stop sprint.

K2_AddActorWorldOffset — move actor by delta in world space

K2_AddActorWorldOffset.
