How to get all enemies dead within radius?

Hello everyone! how i can do when only all enemies are dead in radius to get branch work? i have a bool trigger, and getting all actors of class and each loop makes only the first dead shoot the trigger, how i can make when only all bools are true get branch work?
here is screen of my setup.

create a overlap sphere an get all overlap actors.

i know about that, i mean make the branch work only when all enemies dead, not one of them.

Just initialize a variable to true and if a single one is not dead, set it to false.
some sudo code:

bool AllDead = true;

for each actor in get all actor

if not dead

AllDead = false


It works! Thank you very much mate, i spend few hours trying to resolve this! never knew it was so simple.
