# I need help with this code challenge

class Point { var x: Int var y: Int

```init(x: Int, y: Int){
self.x = x
self.y = y
}
```

}

enum Direction { case Left case Right case Up case Down }

class Machine { var location: Point

```init() {
self.location = Point(x: 0, y: 0)
}

func move(direction: String) {
print("Do nothing! Im a machine!")
}
```

} func move(_ direction: String) { switch direction { case "Up": location.y += 1 case "Down": location.y -= 1 case "Right": location.x += 1 case "Left": location.x -= 1 default: break } }

robots.swift
```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!")
}
}

func move(_ direction: String) {
switch direction {
case "Up":
location.y += 1
case "Down":
location.y -= 1
case "Right":
location.x += 1
case "Left":
location.x -= 1
default:
break
}
}
```

Close but you don't need the initializer also the right is increasing by 1 and the left is decreasing by one

```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) {
switch direction {
case "Up":
self.location.y += 1
case "Down":
self.location.y -= 1
case "Right":
self.location.x += 1
case "Left":
self.location.x -= 1
default:
break
}
}

}
```

You need to create the class Robot that inherits from machine, you also need to override the function using the override keyword

like this? class Robot : Machine { init(x: Int, y: Int) { }

```override func move(_ direction: String) {
switch direction {
case "Up":
self.location.y += 1
case "Down":
self.location.y -= 1
case "Left":
self.location.x += 1
case "Right":
self.location.x -= 1
default:
break
}
}
```

}
