 Card Game Data Structure

Card Game Data Structure
Version: 1.0


Introduction
This is mainly a tool for scripters, This small script contains classes that are very useful in making card games (Ex. BlackJack, Poker, etc.). Includes A Deck Class, A Card class, A Hand class, a Sprite class for Cards. Also includes Card graphics.


Screenshots
Look at the script editor after you add this, there's your screenshot


Demo
Pretty much pointless, see my BlackJack demo for an aplication of this.


Script
Yay the families will be overjoyed...

Instructions
The best way to ensure compatibility is to make classes that inherit from these classes like I did in my BlackJack minigame, I tried to include useful methods in these classes and I will give an explanation of what each of them do here

Name: Game_Deck
Description: The Deck class. Holds in play, discarded, and cards not played yet, automatically shuffles if there are no cards left, also handles multiple decks.
Methods:
  • initialize(number of decks) (private)
    - Creates a new Game_Deck object automatically called from the new method, the parameter number of decks is the number of decks of cards to use (The Default is 1)
  • setup_cards
    - Creates all of the Cards, one for each suit and value
  • shuffle
    - Shuffles the Deck
  • draw(number of cards)
    - Draws number of cards from the deck automatically shuffles if the deck is empty during this process, the parameter number of cards is the number of cards to draw (The default is 1). If only one card is drawn this method will return that card, else it will return an array.
    - Note: will return as many cards as it can if drawing more than one card (All cards could be in play making it unable to shuffle)
  • discard
    - Discards All In Play Cards
  • number(variable amount of strings)
    - Tells how many of cards of suit or value are remaining in the deck. The strings have to match with the constants which is explained further down
  • size
    - Tells how many cards are remaining in the deck
  • delete_in_use_cards (private)
    - Deletes all in play cards from deck, used when reshuffling

Constants:
  • Suits
    -The suits used, by default there are clubs, hearts, diamonds, and spades.
    - Note: remember create a class that inherits from this one and then change the constant in that class if for any reason you want to change it (note you will have to rename/add graphics if if you do)
  • Values
    - The values used, by default A-K (Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, and K). No Jokers.
    - see note for Suits.

Properties:
  • None

Name: Game_Card
Description: The Card class. Represents a card. It is created and used within the Game_Deck class.
Methods:
  • initialize(suit, value, face cards are 10, aces are 11) (private)
    - Creates a new Game_Card object automatically called from the new method, the parameter suit tells the suit of the card, value is the value of the card, face cards are 10 flag telling if face cards (J,Q,K) are worth 10 else their worth is 11,12,and 13 repectively, aces are 11 flag telling if aces are worth 11 instead of 1
  • ace?
    - returns true if the card is an ace
  • jack?
    - returns true if the card is a jack
  • queen?
    - returns true if the card is a queen
  • king?
    - returns true if the card is a jack
  • face?
    - returns true if the card is a face card
  • ten?
    - returns true if the card is worth 10
  • to_s
    - returns a String Representation of this object (The Cards Value)
  • setup_number (private)
    - Sets up the cards worth.

Constants:
  • None

Properties:
  • number (readable)
  • The Cards Worth. (1-13)
  • suit (readable)
  • The Cards Suit.
  • value (readable)
  • The Cards Value. (A-K)
  • flipped (accessible)
  • The Flipped Flag It is set to true in the initialize method.


Name: Game_CardHand
Description: A Class for a Player's Hand, Holds Game_Card objects.
Methods:
  • initialize (private)
    - Creates a new Game_CardHand object automatically called from the new method. Nothing fancy here.
  • each
  • Runs through all cards in hand
  • cards
  • Returns the number of card in hand
  • draw(variable amount Game_Card)
    - Adds Cards to Hand
  • discard
  • Discards (Clears) All cards from Hand
  • to_s
  • returns the string representation of this object, that is the values of all cards in hand

Constants:
  • None

Properties:
  • None

Name: Sprite_Card
Description: A Sprite Class for Displaying Cards.
Methods:
  • initialize(card, flipped flag) (private)
    - Creates a new Sprite_Card object automatically called from the new method. The Parameter card is a Game_Card Object, and the flipped flag tells if the card is displayed face up or face down (The Default is true - face up)
  • flipped=(boolean)
    - Sets the flipped flag, either send true or false to this method

Constants:
  • None[/list[

    Properties:
    • None

    Quote:And if you post what you have now of my stuff then you don't have the latest versions. I'm too lazy/busy to post stuff.
    As this is his material, it is deletable upon his request. Due to his current absense, no support is available. Please do not PM or eMail him for support.


    Compatibility
    Should be compatible with anything as long as you follow my note in the instructions section

umm if i want to make a table in my game so that user can go up to it and play the game how do i do that? please help :)

umm Sorry this is not for nonprogrammers

this is just a library for scripters to write card games you would have to first write a game using this

and then just make a table and call your script
