ALimenLevelSequenceTrigger

Overview

ALimenLevelSequenceTrigger is a gameplay actor that triggers a level sequence when another actor overlaps with its trigger box. It supports various settings to control the behavior, such as enabling/disabling the trigger, specifying allowed actors, and managing the lifecycle of the triggered sequence.

Properties

Type	Name	Access	Description
`UBoxComponent`	TriggerBox	EditAnywhere	The box component that defines the trigger area.
`FName`	UniqueId	EditAnywhere, BlueprintReadOnly	A unique identifier for this trigger.
`TArray<TSubclassOf<AActor>>`	ActorsAllowedToTrigger	EditAnywhere, BlueprintReadOnly	List of actor classes allowed to trigger the sequence.
`ULevelSequence`	LevelSequenceToPlay	EditAnywhere, BlueprintReadOnly	The level sequence to play when triggered.
`FMovieSceneSequencePlaybackSettings`	SequencePlaybackSettings	EditAnywhere, BlueprintReadOnly	Settings for playing the level sequence.
`bool`	bDestroyAfterFinish	EditAnywhere, BlueprintReadOnly	Whether to destroy the trigger after the sequence finishes.
`bool`	bAllowMultipleExecution	EditAnywhere, BlueprintReadOnly	Whether the trigger can be activated multiple times.
`bool`	bLoadSequenceOnLevelStart	EditAnywhere, BlueprintReadOnly	Whether to load the level sequence when the level starts.
`bool`	bStartEnabled	EditAnywhere, BlueprintReadOnly	Whether the trigger is enabled when the level starts.

Functions

Return Type	Signature	Description
`void`	SetTriggerEnabled(const bool bNewEnabled)	Enables or disables the trigger.
`bool`	IsEnabled() const	Returns whether the trigger is currently enabled.
`bool`	ShouldSaveData() const override	Determines if data should be saved for this object.
`bool`	ShouldLoadData() const override	Determines if data should be loaded for this object.
`void`	PreDataSaved() override	Called before data is saved.
`void`	PostDataSaved() override	Called after data is saved.
`void`	PreDataLoaded() override	Called before data is loaded.
`void`	PostDataLoaded() override	Called after data is loaded.
`FName`	GetUniqueDeterministicId() const override	Returns a unique, deterministic ID for this object.

Usage & Implementation Notes

Threading Constraints: This class does not have any specific threading constraints.
Replication Requirements: None.
Memory Lifetime Management: The sequence player and actor are managed using strong and weak pointers to ensure proper garbage collection.
Initialization Dependencies: The trigger box is created in the constructor, and the sequence is loaded based on the bLoadSequenceOnLevelStart property.
