DonatelloPyzza 1.4.1

A simple grid environment to learn Python

DonatelloPyzza

A simple environment to help beginners learn Python in high school. A turtle can move through a grid and touch each cell until it finds the pizza.

You can manually create the grid world in which the turtle moves or generate it automatically (soon).

Documentation

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

FORWARD -> make your turtle go one step forward
TURN_RIGHT -> your turtle will turn on its right
TURN_LEFT -> on its left
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:

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

Now you know how to play, let's create the game and its environment:

# specify the name of the environment
__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.

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

Have fun!
