Sure, there’s nothing inherently wrong with timers, and there’s nothing inherently wrong with tick, but people often use both of them in place of doing things in response to something happening that they could be notified of.
I don’t see anything wrong with notifying every pawn in the game that the player died with a delegate, if they legit need to know about it. Considering that my next action would probably be to do something in the behavior tree, though, i’d just handle it in the behavior tree
