Event BeginPlay — fires once when actor is spawned or game starts

EventBeginPlay — fires once when actor starts

K2Node_Event. No inputs. Always fires once after construction.

BeginPlay

Fires once on actor spawn (after construction). Use for setup that needs other actors in the world to exist.

RestartPlayer — respawn a player at a PlayerStart

Call on GameMode. The controller's StartSpot or nearest PlayerStart is used.

Overlap trigger: detect player entering a zone and do something once

Pattern: EventActorBeginOverlap → CastTo<BP_Character>(Object=OtherActor) → Cast Succeeded → DoOnce → [your action here]. Key pins: EventActorBeginOverlap outputs 'OverlappedActor' and 'OtherActor'. CastTo input is 'Object', exec outputs are 'Cast Succeeded' and 'Cast Failed'. DoOnce exec output is 'Completed'.

EnableInput — allow this actor to receive input events

Must call EnableInput(GetPlayerController(0)) before BindAction/BindAxis events fire on the actor.

EnhancedInputAction — Enhanced Input system action event

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

Respawn system: death → delay → respawn at PlayerStart

In Character BP: OnDied (custom event) → SetActorHiddenInGame(true) → SetActorEnableCollision(false) → Disable input: GetController → DisableInput → Delay(Duration=3.0) → GetGameMode → CastTo<BP_GameMode> → RestartPlayer(GetController) → SetActorHiddenInGame(false) → SetActorEnableCollision(true) → EnableInput. In GameMode RestartPlayer: Gets nearest PlayerStart → SetActorLocation to PlayerStart → calls OnPossess. OR manual: GetAllActorsOfClass(PlayerStart) → Random select → SetActorLocationAndRotation(PlayerStart.Location, PlayerStart.Rotation).

StopMontage — stop a currently playing AnimMontage

Create a Blueprint for a door that opens when the player overlaps a trigger and closes when they leave
