1,441 PointsI'm guessing its a bug or something with tree house but it is telling for the "up" case up increase by 1
I'm guessing its a bug or something with tree house but it is telling for the "up" case the location property y must increase by 1, but that is what I did
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 am a machine!")
}
}
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
}
}
}

instead of decrease it.
Like this:
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 am a machine!")
}
}
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
}
}
}
