Spinbot

class Spinbot extends RobotBrain

The class Spinbot represents the "brains" (or AI) of extremely simple robots that simply spin clockwise and never change location.

  4. def advanceCarefully(): Boolean

    Moves the robot one square forwards, if there is nothing there.

    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.

    returns

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

  8. def controlTurn(): Unit

    Controls the robot body’s actions for a single turn.

    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.

  15. def isStuck: Boolean

    Determines whether or not the robot brain considers the robot to be stuck.

    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.

  17. def locationInFront: grid.GridPos

    Returns the coordinates that point at the square that is immediately in front of this robot.

    Returns the coordinates that point at the square that is immediately in front of this robot.

  18. def mayAdvance(direction: o1.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.

    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 subclasses) 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).

  19. def moveBody(): Unit

    Moves the robot.

    Moves the robot. A spinbot simply spins 90 degrees clockwise as its move.

  20. def name: String

    Returns the robot’s name.

    Returns the robot’s name. If the name has been set to the empty string or contains only whitespace, returns "Incognito" instead.

  21. 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_=("Bob") or simply with an assignment statement: bot.name = "Bob". You won't find many uses for this in O1, but it's nice to know nonetheless.
