Python - Maze Generation Assignment
From WLCS
Contents
Objectives
- You will create a maze generation program
- You will create Python classes that represent a MazeRoom and a Maze
- You will implement a depth-first search maze algorithm using a stack as a backtracker
Resources
MazeRoom class
- Create a file named MazeRoom.py for the MazeRoom class
MazeRoom Attributes
- MazeRoom should have the following attributes with default values:
- roomToNorth - references the a doorway to the north. A None value means that there is wall
- Default: None
- roomToSouth - references the a doorway to the south. A None value means that there is wall
- Default: None
- roomToEast - references the a doorway to the east. A None value means that there is wall
- Default: None
- roomToWest - references the a doorway to the west. A None value means that there is wall
- Default: None
- row - the row number for the Room
- Default: -1
- col - the column number for the Room
- Default: -1
- visited - a Boolean that keeps track of whether or not the room has been visited in the maze algorithm
- Default: False
- roomToNorth - references the a doorway to the north. A None value means that there is wall
MazeRoom Methods
- MazeRoom should have the following method:
- def __init__(self, row = -1, col = -1) - set the internal row and col attributes to be the same as the input parameters
Maze class
- Download the partially completed Maze.py for the Maze class
Maze Attributes
- numRows - an int that stores the total number of rows in your maze
- numCols - an int that stores the total number of cols in your maze
- rooms - a 2-dimensional list of Rooms
Maze Methods
- __init__(self, height=10, width=10):'
- initializes the dimensions of the Maze and creates the 2-dimensional matrix of MazeRooms
- connectRooms(self, r1, r2):
- Takes 2 MazeRooms as input parameters.
- Compares their row and column numbers to figure out their adjacency (relative locations)
- Sets the roomToNorth, roomToSouth, roomToEast, or roomToWest variables accordingly to connect the rooms together.
- isValidRoom(self, row, col):
- Returns True if the row and col numbers are valid and all of the following are True:
- row is non-negative
- col is non-negative
- row is less than numRows
- col is less than numCols
- Returns False otherwise
- Returns True if the row and col numbers are valid and all of the following are True:
- getUnvisitedNeighbors(self, room): - Returns a list of unvisited neighbors of the room parameter
- Create an empty list named neighbors
- countUnvisited(self):
- generate(self):
- print(self): - prints the maze to the screen using characters
Testing
- Create a new file named MazeTest.py and execute the following code:
from Maze import *
maze = Maze()
maze.generate()
maze.print()
