You can’t put them in an array which shows which actor runs the fastest, because the run order is indeterminate.
Technically, I think they are serviced on tick in the order that they were placed ( or spawned ) in the level. But you can’t rely on that.
If you specifically want to run them in a certain order, then you need to do it explicitly. Use an ‘actor manager’ which has an array of the BPs and calls them in a certain order.
