9,345 PointsNot sure how to set up robot's move method.
I'm stuck on this code challenge. As soon as I get to the last part of the question - I can't understand how achieve the goal..
class Point {
var x: Int
var y: Int
init(x: Int, y: Int){
self.x = x
self.y = y
}
}
class Machine {
var location: Point
init() {
self.location = Point(x: 0, y: 0)
}
func move(direction: String) {
print("Do nothing! I'm a machine!")
}
}
class Robot: Machine {
override func move(direction: String) {
}
}

1,814 PointsThis should work.
class Point {
var x: Int
var y: Int
init(x: Int, y: Int){
self.x = x
self.y = y
}
}
class Machine {
var location: Point
init() {
self.location = Point(x: 0, y: 0)
}
func move(direction: String) {
print("Do nothing! I\'m a machine!")
}
}
// Enter your code below
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
}
}
}

9,345 PointsThanks so much! Your code worked perfect. I tried again earlier with example:
case: "Up" location.y += 1
etc. etc. and it did not work, is that really the same as your example?
