"Aldebaran" design
BeeperHunt
This class has the main method of the project. It creates the maze and
robot and GUI
objects of the game and initializes them. The game then runs using GUI
controls.
public
BeeperHunt()
Constructor. Creates a Maze and Robot
public static void main()
Runs the game.
MazeObject
This class is a superclass for objects that are placed in
the game maze.
public
MazeObject(Maze maze)
Constructor. Creates an object at a
random location in a Maze.
public MazeObject(Maze maze, int x,
int y)
Constructor. Creates an object at the
given location in a Maze.
public int getXCoordinate()
public int getYCoordinate()
public int getTurnsTaken()
public abstract void takeTurn()
public int getLifespan()
Getter for lifespan of object, in turns.
public int getTurnsLeft()
Getter for number of turns before this
object expires.
Robot extends MazeObject
public
Robot(Maze maze)
Constructor.
public Beeper findClosestBeeper()
Finds the Beeper with shortest path to
Robot’s current location.
public void takeTurn()
Make one move (could be a “no-op” move)
towards the closest attainable Beeper.
public void collectBeeper(Beeper
beeper)
Pick up the Beeper at the Robot’s
current location, calling the Beeper’s die() method. Increment Robot’s
Beeper count.
Beeper extends MazeObject
As well as defining the Beeper instance, the Beeper class also contains
some general Beeper information in static variables:
private
static Beeper[] beepers
private static MazeVertex
lastBeeperVertex.
public Beeper(Maze maze)
Constructor. Create a Beeper in the
given Maze at a random location.
public Beeper(Maze maze, int row, int
col)
Constructor. Create a Beeper in the
given Maze at the given location.
public void takeTurn()
Increment this Beeper’s age by one. If
it has reached its lifespan limit, call its die() method.
public void die()
Remove this Beeper from the Maze and
generate another one to replace it, by calling the Beeper constructor.
public static Beeper[] getBeepers()
Getter for the array of all Beepers in
the Maze.
public MazeVertex getLastBeeperVertex()
Getter for MazeVertex occupied by the
last Beeper that died.
Maze extends Graph
public
Maze(int size, int subMazeWidth, int subMazeHeight)
Constructor. Create a Maze with size
sub mazes. Sub mazes have specified width and height. Submazes are used
in the construction of the maze.
public void putMazeObject(MazeObject
mo, MazeVertex vertex)
Places a MazeObject at the given
MazeVertex.
public void
removeMazeObject(MazeVertex vertex)
Removes the MazeObject at the specified
x-y coordinate
public Stack
getShortestPath(MazeVertex from, MazeVertex to)
Returns a stack of MazeVertexes
representing the shortest path of legal moves from one MazeVertex to
another.
public MazeVertex[][] getMazeMap()
Get the 2D array of MazeVertexes in the
Maze.
MazeVertex implements Vertex
A MazeVertex has an x-y coordinate, a value, and a boolean “visited”
flag. The value is the MazeObject that occupies that MazeVertex. The
value can be null.
public
MazeVertex(MazeObject mo, int x, int y)
Constructor. Creates a MazeVertex at
the given x-y coordinate, with the MazeObject as its value.
public MazeObject getValue()
Getter for the MazeObject in the
MazeVertex’s value.
public void setValue(MazeObject mo)
Set the MazeObject in the MazeVertex’s
value.
public void setVisited(boolean visited)
Setter for visited boolean.
public boolean getVisited()
Getter for visited boolean.
public int getXCoordinate()
public int getYCoordinate()
Vertex
Interface for a generic vertex in a graph. Vertices are objects that
must have a flag that can be set during searches.
public abstract void
setVisited(boolean visited)
public abstract void getVisited()
Graph
Generic Graph class
public
Graph(int size)
Constructor. Creates a Graph with
number of vertices == size. Once the graph has been created, no
vertices may be added or removed, while existing vertices can be
modified.
public void addVertex(Vertex v)
Adds a vertex to a Graph's Vertex
Collection or Vector.
public void addEdge(Vertex start,
Vertex end)
Creates an edge between two vertices.
public int getSize()
