class Floor extends Square

The class `Floor` represents squares that robots can successfully occupy and move through. On creation, a floor square is always empty, but this changes if a robot arrives.

class RobotBody(val `world`: RobotWorld, `initialLocation`: GridPos, `initialFacing`: CompassDir)

The class `RobotBody` represents virtual robots (or “bots”) which inhabit two-dimensional grid worlds. More specifically, each instance of the class represents a “robot body” (or “chassis” or “hardware”) and basic functionality of such a robot. Each “robot body” is associated with a “robot brain” that controls the body and determines what functionality is activated and when.

The class `RobotBody` represents virtual robots (or “bots”) which inhabit two-dimensional grid worlds. More specifically, each instance of the class represents a “robot body” (or “chassis” or “hardware”) and basic functionality of such a robot. Each “robot body” is associated with a “robot brain” that controls the body and determines what functionality is activated and when.

A robot is equipped with various capabilities:

- It can sense its own surroundings (location, facing, the world that it is in).

- It can spin around in any one of the four main compass directions.

- It can move into the next square in a given direction.

- It can sense whether it is broken or not, and whether it is “stuck” in a square between four walls.

When a robot’s `takeTurn` method is called, it uses its “brain” to figure out what to do (move, turn about, etc.). Robots with different kinds of brains behave differently.

## Parameters

initialFacing

  the direction the robot initially faces in

initialLocation

  the initial location of the robot in its world

world

  the world inhabited by the robot

trait RobotBrain(`initialName`: String, val `body`: RobotBody)

The trait `RobotBrain` represents the “brains” (or artificial “intelligence”) of virtual robots that inhabit two-dimensional grid worlds. A robot brain is equipped with an algorithm for determining what a robot should do during its turn in a robot simulation. In other words, a robot brain is capable of controlling the actions of a robot body.

A robot brain is equipped with an algorithm for determining what a robot should do during its turn in a robot simulation. In other words, a robot brain is capable of controlling the actions of a robot body.

Concrete classes that extend this trait need to provide implementations for the abstract `moveBody` method; each such concrete class can represent a new kind of robot behavior. Overriding the `mayMove` method may also be necessary.

## Parameters

body

  the body the robot brain will control

initialName

  the name of the robot

class RobotWorld(`floorWidth`: Int, `floorHeight`: Int) extends Grid[Square]

An instance of the class `RobotWorld` represents a mutable, two-dimensional world that can be inhabited by virtual robots. This kind of “robot world” is a `Grid` whose elements are `Square` objects.

An instance of the class `RobotWorld` represents a mutable, two-dimensional world that can be inhabited by virtual robots. This kind of “robot world” is a `Grid` whose elements are `Square` objects.

Robots — `RobotBody` objects — can be added to the robot world, and the robot world object maintains a listing of the added robots. It uses this list so that the robots take their turns in a round-robin fashion.

Apart from robots, a robot world can also contain walls. All robot worlds are bounded by walls on all sides: all the edge squares of all robot worlds are always unpassable by robots. Wall squares may also be added at other locations within a world.

## Parameters

floorHeight

  the height of the robot world, in squares, in addition to the walls at the top and at the bottom. The total height of the grid will be two plus this number.

floorWidth

  the width of the robot world, in squares, in addition to the walls on both sides. The total width of the grid will be two plus this number.

trait Square

The trait `Square` represents squares in a robot world, as an abstract concept. A square object is potentially mutable: its state can change as robots enter and exit it. Two concrete kinds of squares have been implemented: `Floor`s and `Wall`s.

class Staggerbot(`name`: String, `body`: RobotBody, `randomSeed`: Int) extends RobotBrain

The class `Staggerbot` represents the “brains” of robots whose algorithms are not sophisticated enough to beat a game of Viinaharava. These robots stagger from place to place harum-scarum, relying on a (pseudo)random number generator.

object Wall extends Square

The singleton object `Wall` represents walls, that is, squares that constitute unpassable barriers for robots. A robot can never be in the same location with a wall.

The singleton object `Wall` represents walls, that is, squares that constitute unpassable barriers for robots. A robot can never be in the same location with a wall.

Since all wall locations in all robot worlds are alike and immutable, it is enough to have a single `Wall` object that can be placed anywhere in any robot world. There is no need for separate instances for each wall square.
