Front End Web Development Techdegree Student 10,462 PointsHello I tried the quiz but it isn't giving me a preview anymore. It just says compiler error
Okay here is my code
class Point { var x: Int var y: Int
init(x: Int, y: Int){
self.x = x
self.y = y
}
} enum Direction { case Left case Right case Up case Down }
class Machine { var location: Point
init() { self.location = Point(x: 0, y: 0) }
func move(direction: String) { print("Do nothing! Im a machine!") } }
class Robot: Machine { override func move(direction: String) { switch direction { case "Up": location.y += 1 case "Down": location.y -= 1 case "Right": location.x += 1 case "Left": location.x -= 1 default: break } } }
I am pretty sure that I am correct. I went through the teamtreehouse iOS forms and it seems almost everybody was having the same problem.
However every time I run this code the compiler just gives me an compiler error, but there is no output? So I am unsure how to fix my error Does anybody know a way around this glitch?
Thanks
class Point {
var x: Int
var y: Int
init(x: Int, y: Int){
self.x = x
self.y = y
}
}
enum Direction {
case Left
case Right
case Up
case Down
}
class Machine {
var location: Point
init() {
self.location = Point(x: 0, y: 0)
}
func move(direction: String) {
print("Do nothing! Im a machine!")
}
}
class Robot: Machine {
override func move(direction: String) {
switch direction {
case "Up":
location.y += 1
case "Down":
location.y -= 1
case "Right":
location.x += 1
case "Left":
location.x -= 1
default:
break
}
}

23,970 PointsIt is not a glitch it looked as they you removed the underscore before
class Point {
var x: Int
var y: Int
init(x: Int, y: Int){
self.x = x
self.y = y
}
}
enum Direction {
case Left
case Right
case Up
case Down
}
class Machine {
var location: Point
init() {
self.location = Point(x: 0, y: 0)
}
//Here
func move(_ direction: String) {
print("Do nothing! Im a machine!")
}
}
class Robot: Machine {
//and here
override func move(_ direction: String) {
switch direction {
case "Up":
location.y += 1
case "Down":
location.y -= 1
case "Right":
location.x += 1
case "Left":
location.x -= 1
default:
break
}
}
}
