How do you import or set the sails to move as tilesets or events?

If you are able to open the sample maps, it shows some examples of positioning and event setup. If not, set your event's movement type to custom, then make a route that uses turn down/left/right/up with waits in between (adjust the waits to your preference). Other than that, it's just a matter of making sure the sail's images are in the character folder.
