Full Stack JavaScript Techdegree Student 33,918 PointsHey Guys,
Here is what I have tried but am stumped at this point. I think it wants to to initialize x and y but Im not sure how?
Please help
class Point { var x: Int var y: Int
init(x: Int, y: Int){
self.x = x
self.y = y
}
}
class Machine { var location: Point
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": y + 1 case "Down": y - 1 case "Left": x - 1 case "Right": x + 1 default: break } } }

1,442 PointsIn the editor you've been provided with two classes - Point to represent a coordinate point and Machine. The machine has a move method that doesn't do anything because most machines are motionless.
Your task is to subclass Machine and create a new class named Robot. In the Robot class, override the move method and provide the following implementation. If you enter the string "Up" the y coordinate of the Robot's location increases by 1. "Down" decreases it by 1. If you enter "Left", the x coordinate of the location property decreases by 1 while "Right" increases it by 1.
Note: If you use a switch statement you can use the break statement in the default clause to exit the current iteration.

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
}
}
}
