You can give actors or components tags like so:
If the actor already has some default tags, you can add more:
There’s also a more advanced system available:
[…]and find their tags in-game
Assuming you meant to find them by tag:
Do note this may not be necessary, you may use Event Dispatchers instead and never look at tags:
You register an event when the actor (tile) comes to play. From now on, every time it’s interacted with, you receive a delegated notification. And this notification can trigger in any actor, not necessarily in the one that spawns the tiles - I vaguely remember something about those tiles being spawned in the LB and you needing their references elsewhere.
This is available as is but you can also add custom event dispatchers, spitting out the very data you need, too. A reference is usually good enough, though.
