Gather Dragon Balls (Blueprint)

I want to create a blueprint actor (DragonBall) that when Overlapping Box Collision with 7 others, opens a new level?
DragonBall Z Style

How would I make this in blueprints?

maybe have 2 actors, the first is the one star dragon ball and the second can be dragonballs 2 through 7. Then have the one star ball on overlap start check how many other balls it’s overlapping. I think there’s a ‘get all overlapping actors’ node which returns an array you can loop through, or use a variable to add/sub balls as overlap starts/ends.

Didnt have time to tak screenshot, but get all actors overlapping of class “dragon_ball” and count array length to see if it is 6 (does not return itself)
