   Enemy Pathfinding
  I am busy with a little game based on a classic 2d-space shooter ( top-down ).All game mechanics are working but I am at a loss on how to make my enemies drop from the top of the screen in predetermined formations and or make them follow a path around the screen.I would appreciate some advice or even a few links to samples if possible.Thank you very much.   
  There were some discussions about this on the Shmup-Dev board.
