So I've created the subclass, but i need help in overriding the values from the superclass. I also have no clue if I'm doing the second part correctly. Please, any help would be 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
class Robot: Machine {
override init(x: Int , y: Int) {
super.init(x: x , y : y )
}
override func move(direction: String) {
"Up"; Point(y) + 1
"Down"; Point(y) - 1
"Left"; Point(x) - 1
"Right"; Point(x) + 1
}
}

override func move(direction: String) {
switch direction {
case "Up" :
super.location.y += 1
case "Down" :
super.location.y -= 1
case "Left" :
super.location.x -= 1
case "Right" :
super.location.x += 1
default:
print("Do nothing! I'm a machine!")
}
}
}
You can access properties of the super class by using the super keyword.
