Pirates? How can I make a boat event sail on the water tiles?

EDIT-

OK I found a script in another post by searching. Nothing helps better then a night's of sleep and a cup of coffee:

I feel like an idiot. I've tried to search, and I know this must be easy to do but I can't get it to work. So I made an event, gave it a boat graphic, created on touch a battle with some pirates. I made a nice graphic that I like, the battle comes up when the player's boat touches the "pirate" ship. But the pirate ship does not sail. It does not move, even if I put on movement etc. I know it's something simple I just cannot find it. Thank you for any help.

This can be a source of confusion:  only the boat that the player is on can move in water. 

To enable that effect for other characters, edit the map_passable? method of Game_Character.  The following script does so if the character's sprite file begins with "@".  (Put this script after all others in the Materials section of the script editor.)

class Game_Character
  alias :petero_boatpassage_map_passable? :map_passable?
  def map_passable?(x, y)
    if @character_name[/^@/]
      return $game_map.boat_passable?(x,y)
    end
    return petero_boatpassage_map_passable?(x,y)
  end
end
