public class Maze

extends Object

Don't panic! You don't have to understand the implementation of this class.

Class Maze describes a maze of height * width rooms. The implementation of the class is rather complicated. Class Maze is only used in the main programs Main1-Main4 and you don't have to create any new mazes, nor use any methods of the class.

Constructor Summary

Maze(int width, int height)
Constructs a height*width maze.

Method Summary

boolean	connectRooms(int x1, int y1, int x2, int y2) This is a rather complicated method that connects several rooms simultaneously by making several doors.
Room	getRoom(int x, int y) Retrieves a room of the maze at coordinates (x, y).
boolean	makeDoor(int x, int y, int direction) Makes a door to the given direction in room (x, y).
void	print() Prints the maze on the terminal.

Constructor Detail

Maze

public Maze(int width,
            int height)

Constructs a height*width maze. Initially, the rooms of the maze have no doors to other rooms.

Parameters:

width - the width of the maze

height - the height of the maze

Method Detail

getRoom

public Room getRoom(int x,
                    int y)

Retrieves a room of the maze at coordinates (x, y).

Parameters:

x - the x coordinate of the room; 0 <= x < width.

y - the y coordinate of the room; 0 <= y < height.

Returns:

the room at position (x, y).

makeDoor

public boolean makeDoor(int x,
                        int y,
                        int direction)

Makes a door to the given direction in room (x, y). Note that all doors are not possible in the border of the maze.

Parameters:

x - the x coordinate of the room; 0 <= x < width.

y - the y coordinate of the room; 0 <= y < height.

direction - the direction of the new door.

Returns:

true if the door could be made and false if the door was not possible.

connectRooms

public boolean connectRooms(int x1,
                            int y1,
                            int x2,
                            int y2)

This is a rather complicated method that connects several rooms simultaneously by making several doors. The coordinates (x1, y1) and (x2, y2) define a rectangle. All rooms inside the rectangle are connected to their neighbors inside the rectangle by doors.

Parameters:

x1 - the x1 coordinate of the room; 0 <= x1 < width.

y1 - the y1 coordinate of the room; 0 <= y1 < height.

x2 - the x2 coordinate of the room; 0 <= x2 < width.

y2 - the y2 coordinate of the room; 0 <= y2 < height.

Returns:

true if all doors could be made and false if some doors were not possible.

print

public void print()

Prints the maze on the terminal. We use simple ASCII graphics. The walls of the rooms are drawn by using letters '-', '|', and '+'. The objects that the rooms contain are drawn by using the labels of the objects.
