You wouldn't have the points as different objects first of all. You would likely have a location point with an instance variable, you create them in the layout and set the instance variable to a number order. Then you create a global variable that relates to the instance variable during gameplay.
So you have one event, find path to location point where locationpoint.var=global variable. So 0 to start with. Then you have another event on arrived at location point, add 1 to global variable and run the find path event again. This would then look for the next location point where the instance variable is 1.
