Did you ever figure this out?
I also want to make a node similar to something like the BeginPlay Event.
My Node should bind itself to events on the “self” actor and fire out execution pins accordingly.
I guess also similar to the InputEvents.
But I have a hard time reading through all the abstraction that makes these nodes work without an Input Exec Pin, but I feel like I might not need to make it that complex to achieve what I want.
