If I want to make a hud and run it so it only picks up the location, how did I go about stringing that location on the hud? For example If I go to one area, I want the hud to have a little button that has visited the area. My main concern is that when I go to the next location, I want that first location to remain green that I have visited it. then I want to be emailed that I have visited all the locations
