ULimenDynamicSpawnerComponent

Overview

ULimenDynamicSpawnerComponent is an abstract actor component that handles the logic for dynamically spawning actors. It provides functionality to start and stop a timer, check if the timer is active, and manage the spawned actors. Subclasses can override methods to customize the spawn behavior.

Properties

Type	Name	Access	Description
`TSubclassOf<AActor>`	ClassToSpawn	EditDefaultsOnly	The class of actor to be spawned.
`float`	SpawnInterval	EditDefaultsOnly	The interval at which actors are spawned.
`int32`	MaxSpawns	EditDefaultsOnly	The maximum number of actors that can be spawned.
`int32`	MaxSpawnRetries	EditDefaultsOnly	The maximum number of retries to find a valid spawn location.
`TArray<TWeakObjectPtr<AActor>>`	SpawnedActors	Private	A list of weak pointers to the currently spawned actors.

Functions

Return Type	Signature	Description
`void`	StartTimer()	Starts a timer that triggers actor spawning at the specified interval.
`void`	StopTimer()	Stops the timer if it is active.
`bool`	IsTimerActive() const	Returns true if the timer is currently active.
`bool`	IsActorSet() const	Returns true if a valid actor class has been set to spawn.
`void`	DespawnAllActors()	Destroys all spawned actors and stops the timer.
`TArray<TWeakObjectPtr<AActor>>`	GetSpawnedActors()	Returns an array of weak pointers to the currently spawned actors.
`bool`	ShouldSpawn()	Determines whether an actor should be spawned. Default implementation always returns true.
`bool`	GetSpawnTransform(FTransform& OutTransform)	Calculates a valid spawn transform for the actor. Default implementation returns false.
`FActorSpawnParameters`	GetSpawnParameters()	Returns the parameters to use when spawning an actor. Default implementation sets collision handling to always spawn.

Usage & Implementation Notes

The component uses a timer to trigger the spawning of actors at regular intervals.
Subclasses can override GetSpawnTransform and ShouldSpawn to customize the spawning logic.
Actors are despawned and the timer is stopped when DespawnAllActors is called.
