DonatelloPyzza 1.6.2

A simple grid environment to learn Python

DonatelloPyzza

DonatelloPyzza is a simple and educational game to help beginners learn Python in high school and university.

A turtle can move through a grid and touch each cells until it finds the pizza. This game can be used at several levels:

• for young beginners: they can hard-code a path to help the turtle find its pizza and small mazes.
• for beginners: they can develop intuitive heuristics to find the pizza
• for intermediate or advanced developers: they can develop a complex path finding method or AI-based solutions.

Installation

pip install -r requirements.txt

pip install donatellopyzza

Getting started

First, import the right modules to run the game:

from donatellopyzza import Game
from donatellopyzza import Action
from donatellopyzza import Feedback

Game is a class that you will use to create a game instance.

Let's create the game and its environment:

# specify the name of the maze
__ENVIRONMENT__ = "maze"
# display the interface (or not)
__GUI__ = True

game = Game(__ENVIRONMENT__, __GUI__)
# returns a turtle that execute actions on its environment
turtle = game.start()

Once the game has started, you get a turtle instance which you can move around the board. To do this, the following instruction can be used:

feedback = turtle.execute(Action.FORWARD)
print(feedback)

You can use the feedback from the execute() method to see what happened after your action.

Learning the rules: actions and feedbacks

Action and Feedback define the different actions and feedbacks types. You can use the following actions in your code:

Action.MOVE_FORWARD -> make your turtle go one step forward
Action.TURN_RIGHT -> your turtle will turn on its right
Action.TURN_LEFT -> on its left
Action.TOUCH -> the turtle will touch the cell in front of it to know its type

Depending on your action, the game can provide you one of the following feedback:

Feedback.COLLISION -> you just tried to walk in a wall !
Feedback.MOVED -> you successfully moved
Feedback.MOVED_ON_PIZZA -> your turtle is on the pizza (congratulation!)
Feedback.TOUCHED_WALL -> you just touched a wall
Feedback.TOUCHED_NOTHING -> the touched cell is empty (no wall, no pizza, you can walk on it)
Feedback.TOUCHED_PIZZA -> the turtle touched the pizza

Generating and save your own mazes

Maze is a class used to generate and save new mazes. You can retrieve saved maze by their names as indicated in example files. A new maze is generated (and save) as follow:

from donatellopyzza import MazeGenerator

generator = MazeGenerator()
maze = generator.create_maze(10, 10)
fn = "test"
maze.save(maze, filename=fn)

For more details, you can find several complete examples of the game loop in the examples folder on the github repository of this project.

Have fun!

What's new

• 2023-04-09 (v1.6) Integration of an algorithm assessment class. Allows to evaluate automatically a solution on several mazes
• 2023-04-07 (v1.5) Integration of a maze generator from Alexandru Văleanu (https://github.com/AlexandruValeanu/Mazify)
• 2023-01-17 (v1.2) Initial release

Roadmap

• adapt the GUI to resize it to the screen size
• make several tests for this package
• make tutorials to help beginners use this package
• make a more formal documentation
• promote this game through a website
• add a test infrastructure to validate users' algorithm on several mazes
• make possible to the user to select the difficulty its maze when generating it
• debug the GUI
• add a gridworld generator
