Trigger once under every X sec?

Does it do something?

If i got:

Every 1 sec

A is overlapping with B

Trigger once

Does it only takes the FIRST A instance overlapping a single B instance? Or it still takes all instances as if Trigger once wasn't there (making it redundant)?

Thanks!

Trigger once won't affect the Picking. Just use "Pick nth instance" with '0'.

trigger once will happen once after x seconds and never again.

What does it do with 0?

It picks the first instance (computers start counting at 0, so it may seem odd, but the 0th instance is the first).

But is it first instance from two selected on A overlapping B?

If A and B are the same object, it will be the first. If A and B are different, you'd need to do it twice to pick the first A and the first B. It all depends on how many As overlap how many Bs, and if they are the same.
