first game, need help with self moving objects.

Hello, and thank you for taking the time to look at my thread. I am currently working on a maze game and I would like to make something (or a number of somethings) that run(s) a set path(s) through the maze, and if a something touches you, it resets the game. I, however, do not posess the know-how to do this. anyone got an answer?

Several options come into my mind:

  • look for action actuator (playing a positional action)
  • look for waypoints (path following)
  • look for steering actuator (integrated path finding and path following)
