Hi there,
Im definitely missing something here. I feel like I'm nearly there but can't quite see whats missing. Any help would be greatly appreciated!!
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! Im a machine!")
}
}
// Enter your code below
let buttons: [String] = ["Up", "Down", "Left", "Right"]
class Robot: Machine {
override func move(_ direction: String) {
for button in buttons {
switch button {
case "Up": self.location.y =+ 1
case "Down": self.location.y -= 1
case "Left": self.location.x -= 1
case "Right": self.location.x += 1
default: print("invalid key entry")
}
}
}
}
