Slaybot

o1.robots.Slaybot
class Slaybot(name: String, body: RobotBody) extends RobotBrain

The class Slaybot represents the “brains” of robots which stand still until they see another unbroken robot. When this happens, they ram the victim with incredible speed.

Parameters

body

the robot body whose actions the slaybot brain will control

name

the name of the slaybot

Concrete methods

def moveBody(): Unit

Moves the robot. During its turn, a slaybot uses its sensors to scan the four main compass directions, always starting with north and continuing clockwise. (It does not change facing while doing this.) When the slaybot notices an intact robot, it turns to face it, instantly moves an unlimited number of squares towards the robot, and rams into it, causing the victim to break. After the collision, the slaybot remains in the square adjacent to its victim, and stops scanning for the rest of the turn. During its next turn, it will start over by scanning north.

After the collision, the slaybot remains in the square adjacent to its victim, and stops scanning for the rest of the turn. During its next turn, it will start over by scanning north.

If there are no victims in any of the four main directions, the robot waits still. It does not attack broken robots. A slaybot can not scan through walls and it can never collide with a wall. It also does not see through robots, not even broken ones.

Attributes

Inherited methods

Moves the robot one square forwards, if there is nothing there. If that square isn’t empty, the robot does not move, so this method never causes a collision.

Attributes

Returns

true if the move was successful and the robot is now in the next square, false if it was blocked

def controlTurn(): Unit

Controls the robot body’s actions for a single turn. If the brain considers the robot to be stuck (see isStuck), this method does nothing. If not stuck, the brain calls its own moveBody method, which carries out the actual robot actions.

RobotBrain

Determines whether or not the robot brain considers the robot to be stuck. A brain considers the robot stuck if and only if all the squares surrounding the robot contain unpassable obstacles, as defined by the mayAdvance method. Only the four nearest squares in the main compass directions are considered.

def mayAdvance(direction: CompassDir): Boolean

Checks the the square that neighbors this robot in the given direction to see if it contains something that the robot brain considers an obstacle. This method is abstract; different kinds of robot brains will have different definitions of what counts as an obstacle.

Checks the the square that neighbors this robot in the given direction to see if it contains something that the robot brain considers an obstacle. This method is abstract; different kinds of robot brains will have different definitions of what counts as an obstacle.

This default implementation (which may be overriden by subtypes) does not consider anything to be an obstacle. Robots that rely on this default implementation are willing to move in any direction and never consider themselves to be stuck (see isStuck).

def name_=(newName: String): Unit

Changes the robot’s name to the given one.

Changes the robot’s name to the given one.

Note to students: In Scala, a method whose name ends in an underscore and an equals sign — like this one’s — can be called using a special syntax. For instance, this method can be called either with the statement bot.name_=("Suzy") or simply with an assignment statement: bot.name = "Suzy". You won’t find many uses for this in O1, but it’s nice to know nonetheless.

Returns the brain of the robot immediately in front of this robot. The brain is returned in an Option wrapper; None is returned if there is no robot in that square or if the robot that is there has no brain.
