GetPlayerController — get the PlayerController for a player index

GetOwningPlayerController — get PlayerController from inside a Widget BP

Pure node. Only works when called INSIDE a Widget Blueprint. Equivalent to GetPlayerController(0) but scoped to the widget owner.

PlayerController

Routes human input to the possessed Pawn. Owns mouse cursor, viewport access, and input mapping.

Controller

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

GetController — get the Controller possessing this Pawn

Pure node. Cast to AIController or PlayerController. Returns null if not possessed.

GetPlayerState — get the PlayerState for a player

Pure node. Call on PlayerController or Pawn. Cast to your BP_PlayerState subclass.

AddMappingContext — add Enhanced Input mapping context to player

Get subsystem: GetSubsystem(UEnhancedInputLocalPlayerSubsystem, GetPlayerController(0)). Call in EventBeginPlay on the Character or PlayerController. Priority: higher number overrides lower number mappings.

GetPlayerController — get player controller by index

UGameplayStatics::GetPlayerController. Index 0 for single player.

Cast to player character subclass and access custom variables

Pattern: GetPlayerCharacter(PlayerIndex=0) → CastTo<BP_MyCharacter>(Object=ReturnValue) → Cast Succeeded → Get/Set variables on 'As BP_MyCharacter' output pin. Key: CastTo exec input='execute', exec output='Cast Succeeded'/'Cast Failed'. The cast output pin is named 'As BP_MyCharacter' (or whatever your class is). Connect this output to any node that needs the typed reference.
