71,830 PointsDavis, here you go:
class Robot: Machine {
override func move (direction: String) {
switch direction {
case "Up":
self.location.y++
case "Down":
self.location.y--
case "Left":
self.location.x--
case "Right":
self.location.x++
default: break
}
}
}
By the way, there's a bug in the challenge code that makes anything you enter look green. That's caused by the single quote inside the double quotes in the function:
func move(direction: String) {
print("Do nothing! I'm a machine!")
}
If you change I'm to Im the color coding returns to normal, and the editor will accept it.
I reported this to Treehouse over a month ago, but heard nothing back from them about it, and clearly they haven't fixed it yet.
