This is confusing to me.
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

Courses Plus Student 6,497 PointsYou need to add another class called Robot. This is where the movement of the robot is calculated:
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
}
}
}
