ALimenFlashlight

Overview

ALimenFlashlight is a subclass of ALimenTool that manages a spotlight and a cone trace component to simulate a flashlight effect. It handles activation, deactivation, and collision detection with actors within its cone of light.

Properties

Type	Name	Access	Description
TObjectPtr	Light	EditDefaultsOnly	The spotlight component that emits the light.
TObjectPtr< ULimenConeTraceComponent >	ConeTrace	EditDefaultsOnly	The cone trace component used to detect actors within the flashlight's range.

Functions

Return Type	Signature	Description
ULimenConeTraceComponent*	GetConeTraceComponent() const	Returns a pointer to the `ULimenConeTraceComponent`.
USpotLightComponent*	GetLight() const	Returns a pointer to the `USpotLightComponent`.
void	ToolActivated() override	Called when the tool is activated. Activates the light and deactivates the cone trace component.
void	ToolDeactivated() override	Called when the tool is deactivated. Deactivates both the light and the cone trace component.
UFUNCTION(BlueprintImplementableEvent)	OnActorLitUpdate(AActor* Actor, const bool bIsInside)	A Blueprint-implementable event that gets called when an actor enters or exits the flashlight's cone of light.

Usage & Implementation Notes

Threading Constraints: This class is designed to be used in the game thread.
Replication Requirements: None.
Memory Lifetime Management: The components (Light and ConeTrace) are created as default subobjects, ensuring they are properly managed by Unreal Engine's garbage collection system.
Initialization Dependencies: The cone trace component listens for collision updates in its constructor.
