ALimenTrigger

Overview

ALimenTrigger is an abstract actor class designed to handle collision events within a defined area. It inherits from ALimenGameplayActor and uses a UBoxComponent for detecting overlaps and hits. The class provides public functions to interact with the trigger component and overrides several lifecycle events to handle these interactions.

Properties

Type	Name	Access	Description
TObjectPtr	CollisionComponent	Private	The box component used for collision detection.

Functions

Return Type	Signature	Description
UBoxComponent*	GetCollisionComponent() const	Returns the `CollisionComponent` property.
void	BeginPlay() override	Initializes the trigger and sets up event bindings.
void	ComponentBeginOverlap(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult)	Called when another actor begins overlapping with the trigger. Logs a message indicating overlap has begun.
void	ComponentEndOverlap(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex)	Called when another actor ends overlapping with the trigger. Logs a message indicating overlap has ended.
void	ComponentHit(UPrimitiveComponent* HitComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, FVector NormalImpulse, const FHitResult& Hit)	Called when another actor collides with the trigger. Logs a message indicating a collision has occurred.

Usage & Implementation Notes

Threading Constraints: None.
Replication Requirements: None.
Memory Lifetime Management: The CollisionComponent is managed by Unreal Engine's garbage collection system.
Initialization Dependencies: The CollisionComponent must be created and configured in the constructor to ensure it is ready for use.
