Line trace from camera to detect what player is looking at

Pattern: GetPlayerController → GetPlayerViewPoint(outputs Location,Rotation) → GetForwardVector(Rotation) → Multiply_VectorFloat(A=Forward, B=TraceDistance) → Add_VectorVector(A=CameraLocation, B=Offset) → LineTraceByChannel(Start=CameraLocation, End=TraceEnd). GetPlayerViewPoint exec in='execute', exec out='then', outputs: 'Location' (Vector) and 'Rotation' (Rotator).

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.

Save and load player data using SaveGame blueprint

SAVE pattern: EventBeginPlay or custom → CreateSaveGameObject(SaveGameClass=BP_SaveGame) → CastTo<BP_SaveGame> → Set all variables on cast result → SaveGameToSlot(SaveGameObject=cast result, SlotName='SaveSlot1', UserIndex=0). LOAD pattern: DoesSaveGameExist(SlotName='SaveSlot1', UserIndex=0) → Branch → True → LoadGameFromSlot(SlotName='SaveSlot1', UserIndex=0) → IsValid → Is Valid → CastTo<BP_SaveGame> → read variables. Key pins: SaveGameToSlot inputs 'SaveGameObject' (SaveGame), 'SlotName' (string), 'UserIndex' (int). LoadGameFromSlot inputs 'SlotName' (string), 'UserIndex' (int), output 'ReturnValue' (SaveGame).
