8,422 PointsI'll run through the steps I took for this one. I started by creating the new subclass...
class Robot: Machine {
}
Next, I added the move method to override the one in Machine...
class Robot: Machine {
override func move(direction: String) {
}
}
Finally, I added a switch to alter the location depending on the value of the direction string...
class Robot: Machine {
override func move(direction: String) {
switch direction {
case "Up": location.y++
case "Down": location.y--
case "Left": location.x--
case "Right": location.x++
default: break
}
}
}
