3,518 Pointshelp on my code
I'm trying to work on my code but its failing inherit the machine function
class Point {
var x: Int
var y: Int
init(x: Int, y: Int) {
s
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!")
}
}
// Enter your code below
enum Direction {
case left
case right
case up
case down
}
class Robot: Machine {
var relocation: Point
override init() {
self.location = Point(x: 0, y: 0)
}
override func move(_ direction: Direction) {
switch direction {
case .up: location.y += 1
case .down: location.y -= 1
case .right: location.x += 1
case .left: location.x -= 1
default: return print(" no input")
}
}
}

57,712 PointsHi there,
Your code seems to have got a bit muddled as there's two declarations of the Point
class - best tidy up the code that the challenge starts with as you won't need to amend any of that.
Next, the directions are given to the move
method. They are of datatype String
- you can't amend that as the tests will test for sending a String
into move
and seeing the Robot
"move".
So, delete your enum; it isn't needed. Have the move
function take a String
parameter and switch on that parameter. The moving part you've done fine but you just need to tweak your statement along the lines of:
switch direction {
case "Up": location.y += 1
.
.
I don't think you need to override init
and the variable, relocation
isn't required either, I don't think. Have a looko at your default
case too - maybe just break
out rather than returning anything?
I hope that helps,
Steve.
