    [VB.NET] Useful Types for Card Games

    Edit: I just remembered that there's a VB 2005 starter kit for a card game so this is probably redundant. Users of previous version can still download the starter kit and open the code files, even if they can't open the project. If anyone has a specific desire for me to continue with this then by all means say so, otherwise I might just leave it.

    Below is some rough code for some types that can form the basis of any card game. They are as yet unfinsihed but I thought I'd post them anyway. I will be making improvements to them myself soon, but feel free to use the code yourself and make your own improvents in the mean time. I intend to create a project that incorporates the Windows cards.dll (or is it cards32.dll, can't remember) at some stage in the future also.
    VB Code:
    1. Public Enum Face
    2.     None 'Used for Jokers
    3.     Ace
    4.     Two
    5.     Three
    6.     Four
    7.     Five
    8.     Six
    9.     Seven
    10.     Eight
    11.     Nine
    12.     Ten
    13.     Jack
    14.     Queen
    15.     King
    16. End Enum
    17.  
    18. Public Enum Suit
    19.     None 'Used for Jokers
    20.     Hearts
    21.     Clubs
    22.     Diamonds
    23.     Spades
    24. End Enum
    VB Code:
    1. Public Structure Card
    2.  
    3.     Private m_Face As Face
    4.     Private m_Suit As Suit

    Cool Re: [VB.NET] Useful Types for Card Games

    to let you know a little about myself i have only been coding vb for about six months the way i coded my cards was to define a type card in a module the code for that is:

    VB Code:
    1. Type card
    2.      Index As Integer
    3.      value As Integer
    4.      suit As String
    5.      picturefront As String
    6.      pictureback As String
    7.      position As Integer
    8.      shuffled As Boolean
    9.      
    10. End Type
    and then in a second module set up a few arrays of type card these are


    VB Code:
    1. Public deck(52) As card
    2. Public firstdeck(52) As card
    3. Public seconddeck(52) As card
    4. Public thirddeck(52) As card
    5. Public fourthdeck(52) As card
    6. Public fithdeck(52) As card
    7. Public sixthdeck(52) As card
    8. Public shoeshuff1(78) As card
    9. Public shoeshuff2(78) As card
    10. Public firsthalfshoe(156) As card
    11. Public secondhalfshoe(156) As card
    12. Public shoe(312) As card
    13. Public path As String
    14. Public item As Integer
    15. Public number1 As Integer
    16. Public number2 As Integer
    17. Public topdeck(26) As card
    18. Public bottomdeck(26) As card
    19. Public tempdeck(52) As card
    20. Public firstQuaterDeck(13) As card
    21. Public secondquaterdeck(13) As card
    22. Public thirdquaterdeck(13) As card
    23. Public fourthquaterdeck(13) As card

    The set up for the cards is simple but longwinded

    VB Code:
    1. Public Function setupcards()
    2. 'sets the actual deck in suit order used at the start form load
    3. Dim count, x As Integer
    4. 'hearts'
    5.  
    6. For x = 52 To 40 Step -1
    7.     deck(x).Index = (x - 39)
    8.     deck(x).suit = "hearts"
    9.         If (x - 39) < 10 Then
    10.            deck(x).value = (x - 39)
    11.         End If
    12.         If (x - 39) > 10 Then
    13.            deck(x).value = 10
    14.         End If
    15. Next x
    16.  
    17. 'clubs
    18.  
    19. For x = 39 To 27 Step -1
    20.     deck(x).Index = (x - 26)
    21.     deck(x).suit = "clubs"
    22.          If (x - 26) < 10 Then
    23.             deck(x).value = (x - 26)
    24.          End If
    25.          If (x - 26) > 10 Then
    26.             deck(x).value = (10)
    27.         End If
    28.  
    29. Next x
    30.  
    31. 'diamonds
    32.  
    33. For x = 26 To 14 Step -1
    34.     deck(x).Index = (x - 13)
    35.     deck(x).suit = "diamonds"
    36.         If (x - 13) < 10 Then
    37.            deck(x).value = (x - 13)
    38.         End If
    39.         If (x - 13) > 10 Then
    40.            deck(x).value = (10)
    41.         End If
    42. Next x
    43.  
    44. 'spades
    45.  
    46. For x = 13 To 1 Step -1
    47.    
    48.     If x < 10 Then
    49.        deck(x).value = x
    50.     End If
    51.     If x > 10 Then
    52.        deck(x).value = 10
    53.     End If
    54.     deck(x).Index = x
    55.     deck(x).suit = "spades"
    56. Next x
    57. For count = 1 To 52
    58.     deck(count).shuffled = False
    59. Next count
    60.  
    61.

    119. deck(52).picturefront = path & "ims\Khearts.jpg"
    120. End Function
    these decks are designed to simulate the packs used in the casino where i work. and so chimile shuffle is an important function i use two random numbers generated here:
    VB Code:
    1. Public Function random()
    2. ' a simple random number gen
    3. Randomize
    4. number1 = 52 * Rnd
    5. Randomize
    6. number2 = 52 * Rnd
    7. checkrandomnumbers
    8. End Function
    and using those perform a selection sort:

    VB Code:
    1. Public Function ChimShuffle()
    2. 'sets up the cards for chim shuffle
    3. Dim count, x, pos As Integer
    4. 'chimmile shuffle
    5. 'set temp deck order to deck order
    6. For count = 1 To 52
    7.      tempdeck(count) = deck(count)
    8.      
    9. Next count
    10. 'perform chim shuffle
    11. For x = 1 To 52
    12.     random
    13.     checkrandomnumbers
    14.     shuffledeck
    15. Next x
    16.  
    17.  
    18. 'put shuffled deck back together in new order
    19. For count = 1 To 52
    20.     deck(count) = tempdeck(count)
    21.     tempdeck(count).shuffled = False
    22. Next count
    23. 'check deck for consistancy
    24. deckcheck
    25. value
    26. For x = 1 To 52
    27.     If deck(x).picturefront = "" Then
    28.        MsgBox ("a card is missaing at position " & x)
    29.     End If
    30. Next x
    31. End Function
    32.  
    33. Public Function shuffledeck()
    34. 'this is the actual chim shuffle it is called from within a fixed itteration loop
    35. 'this works like a slection sort card at position 1 is copied to the same position in the temp deck
    36. 'number 1 is then overwritten by number 2
    37. 'number 2 is then overwritten by number 1 the positions are therefore exchanged
    38.  
    39. 'set deck to hold first random number
    40. deck(number1) = tempdeck(number1)
    41.  
    42. 'set tempdeck to overwrite first number with second number
    43. tempdeck(number1) = tempdeck(number2)
    44.  
    45. 'set tepmdeck to overwrite second number with first
    46. tempdeck(number2) = deck(number1)
    47.  
    48.  
    49. End Function
    The other shuffles are a four way cut and a simple riffle shuffle.
    My initial intention was to start with a simple game like poker and work up to blackjack in a virtual casno then code it in java so that i can plug it into an applet an let it run on my website.
    This is a very longwinded way of doing things but this is an acurate simulation of what happens on a gaming table.

    vb.net Code:
    1. Dim cards = From c In myHand.Cast(Of Card)() _
    2.             Order By c.Suit, c.Face _
    3.             Select c
    That will give you a sorted sequence but it doesn't change the Hand itself. For that you'd have to clear out all the existing Cards and add them all again from the sequence. This code is a bit long in the tooth now anyway so a bit of updating would be in order. For a start, I'd look at inheriting Hand from Collection(Of Card) rather than CollectionBase. I would also add a constructor that would allow creation directly from a list of Cards, which you could get from your LINQ query. You could also have the Card type implement IComparable and then an array or collection could be sorted automatically.

    This is a CodeBank thread so there's no such thing as a late response. I'm afraid that I'm not familiar with that game though, so I wouldn;t be able to answer the question without additional information.

    Re: [VB.NET] Useful Types for Card Games

    Hi, phillt78

    I liked your code, but it seems that there is some code missing.
    checkrandomnumbers()
    deckcheck()
    value()

    is not declared.

    Can you please resubmit the complete code, maybe in a zip file.

    thank you
