How do i make a boat transport system?

Hey guys,

I want to create a boat system for my game which will take the player to the other side of the lake.

This is what I would like to happen:

Player walks on boat, a message box in the center of the screen pops up “would you like to go to the other side?” Two message boxes “Yes” “No” If the player clicks “No”, nothing happens, however if they click “Yes” then the boat travels on a path i decide until it stops.

Many thanks in advance

You should program him to automatically go back and forth and he’ll just say like all aboard! or something
