ULimenInputBindingsLocalPlayerSubsystem

Overview

The ULimenInputBindingsLocalPlayerSubsystem class extends ULocalPlayerSubsystem to handle input bindings specifically for pawns and player controllers. It manages mapping contexts for pawn and player controller inputs, updating bindings when necessary.

Properties

Type	Name	Access	Description
int32	PawnMappingContextPriority	Protected	Priority level for the pawn mapping context.
int32	PlayerControllerMappingContextPriority	Protected	Priority level for the player controller mapping context.

Functions

Return Type	Signature	Description
void	`PlayerControllerChanged(APlayerController* NewPlayerController)`	Called when the player controller changes. Updates bindings accordingly.
void	`AddPawnMappingContext()`	Adds the pawn input mapping context to the enhanced input subsystem.
void	`RemovePawnMappingContext()`	Removes the pawn input mapping context from the enhanced input subsystem.
void	`UpdateControllerBindings(APlayerController* PC)`	Updates the controller bindings based on the current player controller and its possessed pawn.
UFUNCTION()	`InputBindUpdated(const FEnhancedActionKeyMapping& ActionKeyMapping)`	Handles updates to key bindings by requesting a rebuild of control mappings.
UFUNCTION()	`NewPawnNotify(APawn* NewPawn)`	Notifies when the player gains possession of a new pawn, updating input bindings accordingly.
UFUNCTION()	`PossessedPawnChanged(APawn* OldPawn, APawn* NewPawn)`	Handles changes in the possessed pawn by notifying about the new pawn.

Usage & Implementation Notes

Threading Constraints: This subsystem operates on the game thread.
Replication Requirements: None.
Memory Lifetime Management: The subsystem manages weak pointers to player controllers and pawns, ensuring that it does not hold strong references to objects that may be destroyed.
Initialization Dependencies: Depends on UEnhancedInputLocalPlayerSubsystem and ULimenKeyBindSubsystem.
