Managing the lifetime of actors spawned in Consutrction script
Hey there, so my system is as follows: I have several "level pieces" that contain various "obstacles", some of which are spawned in the construction script. I have created several helper functions in C++ that spawn obstacles in particular layouts (Bezier curves, shapes etc.). These functions are called from the Blueprint Construction script of the level piece.
Previously I was using the Blueprint node "AddChildActorComponent" and it worked perfectly. Now I am changing this to C++ I am very confused as to what functions to actually use, and how to properly manage their lifetimes. I was using "GetWorld()->SpawnActor( ObstacleClass, Transform, SpawnParams)" which I would then add to an array of obstacles "TArray< AActor* > Obstacles" which was working correctly. I managed to delete / cleanup the array most of the time but it did not work when the level piece was deleted in the level editor (NOT during game run time). I tried using "OnDestroy", "EndPlay" & "BeginDestroy" and have had no luck, often with it just crashing.
Is there a way I can just hand the spawned obstacle off to the owned parent (the level piece) so that it is automatically handled / destroyed when the level piece is? What are the correct spawning and destroying functions I should be using? Should I be using AChildActorComponent? It seems like this should be extremely simple but I am having great difficulty understanding the huge variance in ways of doing things and what I should be actually using for this situation.
