js_robot_factory's Introduction

Robot factory

Let's implement 3 classes with inheritance

BaseRobot

constructor takes name, weight, coords, chipVersion and saves them
coords should be set to 0 if not passed
goForward, goBack, goRight and goLeft methods take a step argument (1 by default) and move the robot by step in the appropriate direction
getInfo method returns a string in the next format Robot: %name%, Chip version: %chipVersion%, Weight: %weight%

FlyingRobot

inherits all the methods from BaseRobot
takes the same args as BaseRobot and passes them to the parent's constructor
can work with z coords
has methods goUp and goDown changing z coordinate by a given step

DeliveryDrone

inherits all the methods from FlyingRobot and calls its constructor
in addition to FlyingRobot's args it takes maxLoadWeight and currentLoad and saves them.
has hookLoad method taking a cargo object and saving it to a currentLoad property if it is empty and the cargo.weight is not greater than the maxLoadWeight of the drone.
if the drone already has currentLoad do not change it
has unhookLoad method, that currentLoad property to null

DeliveryDrone {
  name: string
  weight: number
  chipVersion: number
  maxLoadWeight: number
  currentLoad: null || {
    weight: number
    description: string
  }
  coords: {
    x: number
    y: number
    z: number
  }
}
