8,185 PointsNot sure how to override this function.
I know what I need to do, I just can't override the function to return Integers instead of strings so I can add onto or take away from the location X and Y coordinates.
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! I'm a machine!")
}
}
class Robot: Machine {
override func move(direction: String) {
if direction == "up" {
}
}
}

Try the following for me.
class Robot: Machine {
override func move(direction: String) {
switch direction {
case "Up": location.y += 1
case "Down": location.y -= 1
case "Left": location.x -= 1
case "Right": location.x += 1
default: break
}
}
}
