ULimenProximityInteractionComponent

Overview

ULimenProximityInteractionComponent is a custom component that extends ULimenInteractionComponent. It detects and manages interactions with interactable components within a specified range. The component uses a sphere to detect overlapping actors and updates the list of interactables accordingly.

Functions

Return Type

Signature

Description

const TArray< ULimenInteractableComponent *>&

GetAllInteractablesInRange() const

Returns a list of interactable components within the interaction range.

const TArray<AActor*>&

GetAllInteractableActorsInRange() const

Returns a list of actors that own the interactable components within the interaction range.

void

RestartInteraction() override

Restarts the interaction by re-setting up the component.

void

SetupInteraction() override

Sets up the interaction sphere and registers overlap events.

void

UpdateInteraction(const float DeltaTime) override

Updates the list of interactables based on current proximity and handles debug drawing if enabled.

UFUNCTION()

OnInteractionSphereBeginOverlap(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult)

Handles the begin overlap event for the interaction sphere.

UFUNCTION()

OnInteractionSphereEndOverlap(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex)

Handles the end overlap event for the interaction sphere.

bool

IsInsideSphere(const UPrimitiveComponent* InteractableComponent) const

Checks if an interactable component is within the interaction range.

void

CheckActorsInInsideRadius()

Updates the lists of interactable components and actors based on current proximity in the world.

Usage & Implementation Notes

  • Threading Constraints: This component operates on the game thread.

  • Replication Requirements: None.

  • Memory Lifetime Management: The interaction sphere is dynamically created and destroyed during setup and teardown.

  • Initialization Dependencies: Depends on ULimenInteractionComponent for base functionality.
