How to make actor go to a loction using a list?

I really don’t know how to ask this question, but, what im trying to do is, i wanna make an actor go to the next location in an array list that i have made. instead of it being random, i would like it to just go down the list and then restart back at the top when it reaches the bottom. who can show me how to do this?

so i know how to make the array search randomly, im an expert on this by now, but how do you make it so the game will go in synchronization form down the list?

if VectorLength( VectorYourLoc1 - VectorDesiredLoc2 ) < 1.0 varactualindex ++ , plug it into the index get on the array.
