1,061 PointsHi, I am stuck in this challenge. Would be great to get some tips. Thanks.
// code obviously doesn't work :D
class Robot: Machine { override init() { super.init() }
override func move(_ direction: String) {
switch move {
case "Up":
self.location = Point(x: 0, y: 1)
case "Down":
self.location = Point(x: 0, y: -1)
case "Left":
self.location = Point(x: -1, y: 0)
case "Right":
self.location = Point(x: 1, y: 0)
default: break
}
}
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 am a machine!")
}
}
// Enter your code below

23,970 PointsHi Miguel - The first error is that you are not switching on (direction) instead you have move. The next error is on your return statements for the cases. The correct code is below
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) {
switch direction {
case "Up":
location.y += 1
case "Down":
location.y -= 1
case "Left":
location.x -= 1
case "Right":
location.x += 1
default:
break
}
}
}
