9,277 PointsStuck On It
I'm on the preview and i don't understand what is still the problem.
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 Robot {
var location: Point
init() {
self.location = Point(x: 0, y: 0)
}
func move(direction: Direction) {
// Enter your code below
func enum_move(direction: Direction){
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
}
}
}

8,386 PointsYou are really close, I see two problems: 1) You removed the underscore for the external parameter name in the move func (just add it back)
2) You don't need the func enum_move line (remove it)
Here's the code (it passed when I tested it):
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 Robot {
var location: Point
init() {
self.location = Point(x: 0, y: 0)
}
func move(_ direction: Direction) {
// Enter your code below
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
}
}
}
