I am not sure what I am doing wrong.
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!")
}
}
// Enter your code below
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
}
}
}

Front End Web Development Techdegree Graduate 46,473 PointsHi Evan! You've nearly got it - just one little bit:
When you do the switch statement, you only need to switch on the word direction - the underscore is what is used when calling the method later:
switch direction {
case "Up" : location.y += 1
case "Down" : location.y -= 1
case "Left" : location.x -= 1
case "Right" : location.x += 1
default : break
}
Hope that helps - let me know if you have any questions ???

2,607 PointsThanks a lot Alexandra! I looked at other people's code before and still couldn't get it, but I did as you told and it worked. Thanks again! :)
