execute array on random timer

this might be really easy or really hard.

i have a cluster of objects you can toggle visibility on with a master switch. it works by getting all actors with tag and switching off visibility in game.

i want to have it so they dont all blink in and out of existance at the same time, so some kind of random timer or progressive array is what i need.

If each of those objects are BPs, then create a custom event or function with a delay with a random time to toggle or turn off the light:

Now, in the master switch you can call that custom event of all objects and they will turn off at random times:
