ULimenInteractionComponent

Overview

ULimenInteractionComponent serves as a base class for defining interaction mechanics, including hover and interact events, as well as interaction-specific logic such as handling line of sight and interaction ranges. It is designed to be replicated across the network and supports both client and server interactions.

Properties

Type	Name	Access	Description
`TObjectPtr<AController>`	Controller	Public	The controller associated with the interaction component.
`TObjectPtr<APawn>`	Pawn	Public	The pawn associated with the interaction component.
`FRepInteractionParams`	InteractionParams	Private	Parameters for replication, including controller and pawn.
`FRepInteractionUpdateData`	InteractionUpdateData	Private	Data used for replication of interaction updates.
`bool`	bDebugMode	Public	Debug mode flag to enable additional debugging tools or visualizations.
`float`	InteractionRange	Public	The maximum range within which interactions can occur.

Functions

Return Type	Signature	Description

`APawn*`	GetInteractionPawn() const	Retrieves the pawn associated with the interaction component.
`ULimenInteractableComponent*`	GetCurrentInteractableComponent() const	Retrieves the current interactable component.
`bool`	GetOwnerViewPoint(FVector& Start, FVector& End) const	Retrieves the view point start and end vectors for the component's owning actor.

Usage & Implementation Notes

Threading Constraints: This component is designed to be used on both client and server threads.
Replication Requirements: The InteractionParams and InteractionUpdateData properties are replicated using REPLIFETIME_WITH_PARAMS_FAST.
Memory Lifetime Management: The component uses weak pointers (TWeakObjectPtr) for managing the lifetime of interactable components, ensuring that memory is properly managed without causing dangling references.
Initialization Dependencies: The component requires a valid owner actor with authority to set up interaction mechanics.
