8,536 PointsDo I need a 'self' here?
For the second part of this challenge, it asks me to add the subclass Robot with the functionality to move. My code is as follows:
class Machine {
var location: Point
init() {
self.location = Point(x: 1, y: 1)
}
func move(direction: String) {
print("Do nothing! Im a machine!")
}
}
class Robot: Machine {
override init() {
super.init()
}
override func move(direction: String) {
switch direction {
case "Up": location.y = location.y + 1
case "Down": location.y = location.y - 1
case "Left": location.x = location.x - 1
case "Right": location.x = location.x + 1
default: break
}
}
}
My question is in the switch statement, do I need to say
self.location.y = self.location.y + 1
or is it fine the way it is?
