UNO!

Student Project for learning C++

Methodologies

1. Array Pairs
   • Uses 2 synced pairs and a dictionary
     • p1[] : Contains the integer values of the Number of each Card in Player 1's deck, is synced with cp1[]
     • cp1[] : Contains the integer values of the Colour of each Card in Player 1's deck, is synced with p1[]
     • dictionary[] : Converts the integer values in p1[] and cp1[] to strings describing the features of the card
   • Discontinued due to data handling complexity
2. Card Class
   • Uses a custom class Card
     • All object with the class Card have integer values for Colour and a Number
     • All objects with type Card have a built-in Ditcionary which describes the feature of the card when the functions printColour() and printNumber() are used
   • Discontinued due to data handling complexity
3. Card Class with Universal Array
   • Uses a custom class Card
     • All object with the class Card have integer values for Colour and a Number
     • All objects with type Card have a built-in Ditcionary which describes the feature of the card when the functions printColour() and printNumber() are used
   • Uses a Universal Array instead of multiple different arrays
     • All cards are in a single Array called Piles[]
     • Piles[] is seperated into six regions of 108 in the following order
       • Draw Pile
         • Red Cards
         • Blue Cards
         • Green Cards
         • Yellow Cards
         • Colourless Cards
       • Player 1
       • Player 2
       • Player 3
       • Player 4
       • Discard Pile
     • A function Offset() is used to obtain data using an index between 0 and 107 instead of 0 and 647. This makes it easier to perform card manipulation procedures
   • Discontinued due to integrating complexity
4. Game Class, Card Class and Universal Array
   • Uses a custom class UNO which contains all the game functions and data
     • All cards are in a single Array called Piles[]
       • Piles[] is seperated into six regions of 108 in the following order
         • Draw Pile
           • Red Cards
           • Blue Cards
           • Green Cards
           • Yellow Cards
           • Colourless Cards
         • Player 1
         • Player 2
         • Player 3
         • Player 4
         • Discard Pile
     • A function Offset() is used to obtain data using an index between 0 and 107 instead of 0 and 647. This makes it easier to perform card manipulation procedures
   • Uses a custom class Card
     • All object with the class Card have integer values for Colour and a Number
     • All objects with type Card have a built-in Ditcionary which describes the feature of the card when the functions printColour() and printNumber() are used

Target Description

• To initaialize the cards
• To input
  • The number of Players
  • The number of Cards each player should have
• To shuffle the Cards for each Player based on input
• To take 1 card from the remaining Draw pile and set it as the Discard pile
• To play the game in a clockwise manner {P1 - P4} until changed by a Reverse card
• To ensure the players can only put cards which match the top of the Discard pile by either Number or Colour
• To allow the player to draw a card from the Draw pile
• To complete appropriate processes for each action card
• To declare a "Player 1 has gotten n^th Position" after the game has ended

Game Description

Purpose

• This is the logic unit for a multiplayer UNO card game
• The code is built in such a way to allow it to be integrated to a GUI with only slight modifications

Input Stream

• The Game uses only integers for inputs
• The first two inputs are pre-game inputs selecting the number of players who will be playing and the number of cards each player will start with
• Once the game starts it will take indexes as inputs
  • Each player can play a card in their deck by inputting the index of the card they want to play which can only be from 0-107
  • They can input -1 to draw a card
  • They can input -2 to indicate they have completed their turn
• Each player must have placed atleast one card or drawn 1 card before they can pass their turn
• Valid Inputs during pre-game : Players => 1 - 4 , Cards => 1 - 21
• Valid Inputs during game : Index => -2 - 107

Output Stream

• The game will generate properly described prompts whecn asking for each input
• The game will output each player's hands and the discard pile every time a player passes a turn
• The game will output a leaderboard when only 1 player is left
