python代写 | MVC代写 – 这是一个利用python进行MVC编程的题目
Uno++
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 from the popular card game, Uno. 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 implemented the modelling classes, you will have completed a digital version of Uno that follows the MVC pattern.
Gameplay
Uno is a card based game consisting primarily of cards with both a colour and a number. Each player starts with a deck of seven cards. The player whose cards are visible is the starting player. Once the player makes a move by selecting their card to play, their cards will be hidden and it will move to the next players turn.
There are two piles in the middle of the board. The left pile is the pickup pile, a player should click this pile if they have no cards to play, it will add a card to their deck. The right pile is the putdown pile, a player has to pick a card from their deck which matches the card on top of the putdown pile.
The aim of the game is to have no cards left in your deck. Each turn a player can either select a card from their pile which matches the card on top of the putdown pile, or, they can pickup a new card from the pickup pile if they have no matching cards.
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
player.txt – a list of random player names to use for computer players
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.
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.
Cards
A card represents a card in the uno game which has colour and number attributes.
Card
The basic type of colour and number.
Instances of Card should be initialized with Card(number, colour). The following methods must be implemented:
get_number(self): Returns the card number
get_colour(self): Returns the card colour
set_number(self, number: int): Set the number value of the card
set_colour(self, colour: a2_support.CardColour): Set the colour of the card
get_pickup_amount(self): Returns the amount of cards the next player should pickup
matches(self, card: Card): Determines if the next card to be placed on the pile matches this card.
"Matches" is defined as being able to be placed on top of this card legally.
A "match" for the base Card is a card of the same colour or number.
play(self, player: Player, game: a2_support.UnoGame): Perform a special card action. The base Card class has no special action.
Hint: Look at the a2_support.UnoGame methods
str(self): Returns the string representation of this card.
repr(self): Same as str(self)
For the following examples, assume that the below code has been executed:
####### >>> anna = ComputerPlayer("Anna Truffet")
####### >>> players = [anna, HumanPlayer("Henry O’Brien"),
####### ComputerPlayer("Josh Arnold")]
####### >>> deck = Deck([Card(1, "red"), Card(2, "blue"),
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.
SkipCard
A card which skips the turn of the next player. Matches with cards of the same colour.
Examples
ReverseCard
A card which reverses the order of turns. Matches with cards of the same colour.
Examples
####### Card(3, "red"), Card(4, "green")])
####### >>> game = a2_support.UnoGame(deck, players)
####### >>> card = SkipCard(0, "blue")
####### >>> game.current_player().get_name()
####### ‘Anna Truffet’
####### >>> card.play(anna, game)
####### >>> game.current_player().get_name()
####### "Henry O’Brien"
####### >>> card = ReverseCard(0, "red")
####### >>> game.current_player().get_name()
####### ‘Anna Truffet’
####### >>> game.next_player().get_name()
####### "Henry O’Brien"
####### >>> game.next_player().get_name()
####### ‘Josh Arnold’
####### >>> game.next_player().get_name()
####### ‘Anna Truffet’
####### >>> card.play(anna, game)
Pickup2Card
A card which makes the next player pickup two cards. Matches with cards of the same colour
Examples
Pickup4Card
A card which makes the next player pickup four cards. Matches with any card.
Examples
####### >>> game.next_player().get_name()
####### ‘Josh Arnold’
####### >>> game.next_player().get_name()
####### "Henry O’Brien"
####### >>> game.next_player().get_name()
####### ‘Anna Truffet’
####### >>> game.next_player().get_deck().get_cards()
####### []
####### >>> card = Pickup2Card(0, "red")
####### >>> card.play(anna, game)
####### >>> game.next_player().get_deck().get_cards()
####### [Card(3, red), Card(4, green)]
####### >>> game.next_player().get_deck().get_cards()
####### []
####### >>> card = Pickup4Card(0, "red")
####### >>> card.play(anna, game)
####### >>> game.next_player().get_deck().get_cards()
####### [Card(1, red), Card(2, blue), Card(3, red), Card(4,
####### green)]
Examples
Deck
A collection of ordered Uno cards. A Deck should be initialized with Deck(starting_cards=None)
get_cards(self): Returns a list of cards in the deck.
get_amount(self): Returns the amount of cards in a deck.
####### >>> card = Card(23, "yellow")
####### >>> card.str()
####### ‘Card(23, yellow)’
####### >>> card
####### Card(23, yellow)
####### >>> card = Card(42, "red")
####### >>> card.get_number()
####### 42
####### >>> card.get_colour()
####### ‘red’
####### >>> card.set_number(12)
####### >>> card.get_number()
####### 12
####### >>> card.get_pickup_amount()
####### 0
####### >>> special_card = Pickup2Card(0, "red")
####### >>> special_card.get_pickup_amount()
####### 2
####### >>> special_card.matches(card)
####### True
####### >>> card.matches(special_card)
####### True
####### >>> blue_card = ReverseCard(0, "blue")
####### >>> special_card.matches(blue_card)
####### False
shuffle(self): Shuffle the order of the cards in the deck.
pick(self, amount: int=1): Take the first ‘amount’ of cards off the deck and return them.
add_card(self, card: Card): Place a card on top of the deck.
add_cards(self, cards: list
top(self): Peaks at the card on top of the deckand returns it or None if the deck is empty.

####### [Pickup2Card(0, red), Card(12, red)]
####### >>> deck.shuffle()
####### >>> deck.get_cards()
Players
A player represents one of the players in a game of uno.
Player
The base type of player which is not meant to be initiated (i.e. an abstract class).
The Player class should be initiated with Player(name) and implement the following methods:
get_name(self): Returns the name of the player.
get_deck(self): Returns the players deck of cards.
is_playable(self): Returns True iff the players moves aren’t automatic.
Raises a NotImplementedError on the base Player class.
has_won(self): Returns True iff the player has an empty deck and has therefore won.
pick_card(self, putdown_pile: Deck): Selects a card to play from the players current deck.
Raises a NotImplementedError on the base Player class.
Returns None for non-automated players or when a card cannot be played.
If a card can be found, the card should be removed.
Each of the following classes should be a subclass of Player and should only alter methods required to implement the functionality as described.
####### [SkipCard(0, green), Card(12, red), Pickup2Card(0, red),
####### ReverseCard(0, blue)]
HumanPlayer
A human player that selects cards to play using the GUI.
ComputerPlayer
A computer player that selects cards to play automatically.
Examples
####### >>> player = Player("Peter O’Shea")
####### >>> player.get_name()
####### "Peter O’Shea"
####### >>> player.get_deck()
####### <main.Deck object at 0x10e56cd68>
####### >>> player.get_deck().get_cards()
