Introduction
This assignment follows a programming pattern called MVC (the Model, View, Controller)
pattern. You have been provided with the view and controller classes but you will be required
to implement several modelling classes.
The modelling classes are based on the children’s card game, Sleeping Queens. Each class
you’re required to implement has a specification that is outlined in this document. A
specification is a description of each method in a class as well as their parameters and return
values.
Once you have correctly implemented the modelling classes, you will have completed a digital
version of Sleeping Coders.
Gameplay
Sleeping Coders (Coders for short) is a card game that is based on the popular children’s card
game, Sleeping Queens. The aim of the game is to wake as many sleeping coders as
possible. A sleeping coder is woken by playing a tutor card.
At the start of the game there are 16 coders placed face down in the center of the board, a
face down coder card means that coder is sleeping. Each player is dealt five cards randomly.
Basic Running of the Game
Players will take turns playing a card from their deck; number cards have no action and are
meant to be disposed of while other cards have actions attributed to their playing.
A tutor card can be played at any time. When a tutor card is played the player who played it
can pick up one of the coder cards from the center of the board.
Playing a keyboard kidnapper card will allow the player to take a coder card from another
player.
Playing an all-nighter card will allow the player to put another player’s coder back to sleep (add
it back to the center of the board).
The aim of the game is to collect coders by waking them up. The first player to collect 4 coders
wins the game.
Getting Started
Files
a2.py – file where you write your submission
a2_support.py – contains supporting code and part of the controller
gui.py – contains the view
players.txt – a list of random player names
images/ – a directory of card images
Classes
In the diagram below, an arrow indicates that one class stores an instance of another class. An
arrow with a head indicates that one class is a subclass of another class. Red classes are
classes that have been provided already.
You are encouraged to modify the class structure by adding classes to reduce code
duplication. This can include adding private helper methods.
The type hints shown in the methods below are purely for your own understanding. Type hints
do not need to be used in your assignment.
For all of the examples in the section below, you may assume that the following code has
already been executed before each example.

>>> from a2 import *
>>> import a2_support
It is advisable that you implement the and methods after
implementing all of the classes (including Player and Deck)
Cards
A card represents a card in the game, which may be a coder card or a playable card held by
the players in the game.
Card
The base card with methods for playing a card and performing a card action. Subclasses of
Card should override these methods.
The following methods must be implemented:
play(self, player: Player, game: a2_support.CodersGame): Called when a player plays a
card. Should remove the card from the player’s hand and pickup a new card from the pickup
pile in the game. Should also set the action that needs to be performed (see
). If no action needs to be performed, set the action to
‘NO_ACTION’.
action(self, player: Player, game:a2_support.CodersGame, slot: int): Called when an
action of a special card is performed. For tutor cards, this action is selecting a coder from the
pile. For keyboard kidnapper and all-nighter cards, this is selecting a coder from another
player’s hand. For all other cards, no action needs to be performed. When playing a tutor card,
the player refers to the current player. When playing a keyboard kidnapper card or all nighter
card, the player refers to the player to which the coder belongs to.
__str__(self) -> str: Returns the string representation of this card, this should be ‘Card()’.
__repr__(self) -> str: Same as __str__(self).
Each of the following classes should be a subclass of Card and should only alter
methods required to implement the functionality of the card as described.
NumberCard
>>> peter = Player(“Peter O’Shea”)
>>> players = [peter, Player(“Jason Storey”), Player(“Mike
Pham”)]
>>> coders = [CoderCard(“anna”), CoderCard(“lochie”)]
>>> deck = Deck([NumberCard(2), NumberCard(4), NumberCard(1)])
>>> game = a2_support.CodersGame(deck, coders, players)
Card.play Card.action
CodersGame.set_action
A card whose aim is to be disposed of by the player. A number card has an associated number
value.
A number card should be constructed with NumberCard(number).
When a number card is played, the game should move on to the next players turn.
get_number(self) -> int: Returns the number value of the card.
Examples
CoderCard
A card which stores the name of a coder card.
A coder card should be constructed with CoderCard(name).
get_name(self) -> str: Returns the card name.
Examples
TutorCard
A card which stores the name of a tutor card.
A tutor card can be played by a player to pickup a coder card.
A tutor card should be constructed with TutorCard(name).
>>> card = NumberCard(3)
>>> card.get_number()
3
>>> str(card)
‘NumberCard(3)’
>>> repr(card)
‘NumberCard(3)’
>>> card = CoderCard(“hanwei”)
>>> card.get_name()
‘hanwei’
>>> str(card)
‘CoderCard(hanwei)’
>>> repr(card)
‘CoderCard(hanwei)’
When a tutor card is played, the game’s action should be set to ‘PICKUP_CODER’.
When a tutor card’s action is performed, the selected card should be added to the player’s
deck, the position of the card in the sleeping coders’ deck should be replaced with None, the
action should be set back to ‘NO_ACTION’ and the game should move on to the next player.
get_name(self) -> str: Returns the card name
Examples
KeyboardKidnapperCard
A card which, when played, allows the player to steal a coder card from another player.
When a keyboard kidnapper card is played the games action should be set to
‘STEAL_CODER’.
When a keyboard kidnapper card’s action is performed, the selected card should be added to
the current player’s deck and removed from its origin deck, the action should be set back to
‘NO_ACTION’ and the game should move on to the next player.
Examples
AllNighterCard
A card which, when played, allows the player to put a coder card from another player back to
sleep.
When an all-nighter card is played, the game’s action should be set to ‘SLEEP_CODER’.
>>> card = TutorCard(“luis”)
>>> card.get_name()
‘luis’
>>> str(card)
‘TutorCard(luis)’
>>> repr(card)
‘TutorCard(luis)’
>>> card = KeyboardKidnapperCard()
>>> str(card)
‘KeyboardKidnapperCard()’
>>> repr(card)
‘KeyboardKidnapperCard()’
When an all-nighter card’s action is performed, the selected card should be added to the first
empty slot in the coders’ pile and removed from its origin deck, the action should be set back to
‘NO_ACTION’ and the game should move on to the next player.
Examples
Deck
A collection of ordered cards. A Deck should have a constructor with a signature of
When starting_cards is None, i.e. constructed with Deck(), it should be created with an empty
list.
When starting_cards is provided, i.e. constructed with Deck(starting_cards=cards), it should be
created with that list.
get_cards(self) -> List[Card]: Returns a list of cards in the deck.
get_card(self, slot) -> Card: Return the card at the specified slot in a deck.
top(self) -> Card: Returns the card on the top of the deck, i.e. the last added.
remove_card(self, slot): Removes a card at the given slot in a deck.
get_amount(self) -> int: Returns the amount of cards in a deck.
shuffle(self): Shuffles the order of the cards in the deck.
pick(self, amount: int=1) -> List[Card]: Takes the first ‘amount’ of cards off the deck and
returns them.
add_card(self, card: Card): Places a card on top of the deck.
add_cards(self, cards: List[Card]): Places a list of cards on top of the deck.
copy(self, other_deck: Deck): Copies all of the cards from the other_deck parameter into the
current deck, extending the list of cards of the current deck.
__str__(self) -> str: Returns the string representation of the deck, for a deck which contains
cardA, cardB and cardC, this should be ‘Deck(cardA, cardB, cardC)’.
>>> card = AllNighterCard()
>>> str(card)
‘AllNighterCard()’
>>> repr(card)
‘AllNighterCard()’
Deck(starting_cards=None)

Feedback Sessions
In week 10, you must attend the practical that you are signed onto on mySI-net where the tutor
who assessed your assignment will provide you with feedback.
When you arrive at the feedback session please take a seat but don’t sit in the row furthest
from the door as this will be where tutors will be providing feedback and it will be need to be
kept free for privacy.
Allow for being in attendance at the practical for the full 2 hours, when your name is called
walk over to the tutor who called your name and they will provide you with feedback on your
assignment. You can leave once you have discussed your assignment with a tutor.
Assignment Submission
Your assignment must be submitted via the assignment one submission link on Blackboard.
You must submit a Python file, , containing your implementation of the assignment.
Late submission of the assignment will not be accepted. Do not wait until the last minute to
submit your assignment, as the time to upload it may make it late. Multiple submissions are
allowed, so ensure that you have submitted an almost complete version of the assignment well
before the submission deadline. Your latest on-time, submission will be marked. Ensure that
you submit the correct version of your assignment. An incorrect version that does not work will
be marked as your final submission.
In the event of exceptional circumstances, you may submit a request for an extension. See the
course profile for details of how to apply for an extension. Requests for extensions must be
made no later than 48 hours prior to the submission deadline. The expectation is that with less
than 48 hours before an assignment is due it should be substantially completed and
a2.py
submittable. Applications for extension, and any supporting documentation (e.g. medical
certificate), must be submitted via my.UQ. You must retain the original documentation for a
minimum period of six months to provide as verification should you be requested to do so.
