I have this F# program:

code:

open System
open System.IO
open System.Text

let rnd = System.Random()

type PlayingCard(rank) =
    member this.Rank = rank

    member this.Name =
        match (this.Rank % 13) with
        | 0 -> "A"
        | 10 -> "J"
        | 11 -> "Q"
        | 12 -> "K"
        | _ -> (this.Rank % 13).ToString();

    member this.Suit =
        match this.Rank with
        | x when x >= 0 && x < 13 -> "s"
        | x when x >= 13 && x < 26 -> "c"
        | x when x >= 26 && x < 39 -> "h"
        | x when x >= 39 && x < 52 -> "d"
        | _ -> "?"

    member this.DisplayName =
        let sw = new StringBuilder()
        sw.AppendFormat("{0}{1}", this.Name, this.Suit)

    member this.ToString =
        this.DisplayName.ToString()

let DisplayHand hand =
    let sw = new StringBuilder()
    for card : PlayingCard in hand do
        sw.AppendFormat("{0}{1} ", card.Name, card.Suit) |> ignore
    sw.ToString()

let MakeRandomCard = new PlayingCard(rnd.Next(0, 52))
let DealHand = [MakeRandomCard; MakeRandomCard]

[<EntryPoint>]
let main argv = 
    let playerHand = DealHand
    let dealerHand = DealHand
    printfn "Player: %s" (DisplayHand playerHand)
    printfn "Dealer: %s" (DisplayHand dealerHand)
    0

the result of every MakeRandomCard is the same and I can't figure out why. rnd is in global scope so it shouldn't be re-seeding it with the system time four times in the same instant. if I replace them with just inlining new PlayingCard(rnd.Next(0, 52)) it works.

probably because make random card is a variable and not a function. put parentheses after it so that it takes a unit as input and returns a new playing card every time. same with deal hand

you are calling rnd.next once when it is passed as a parameter to the delegate.

like i think your program would be much simpler if used types like these and don't even bother with making "classes" that have to be instantiated

code:

type Rank =
	| Bullshit of int
	| Ace
	| Jack
	| Queen
	| King

type Suit = 
	| Spade
	| Club
	| Heart
	| Diamond
	
type PlayingCard = {
	Rank: Rank
	Suit: Suit
}

also you probably want to generate a sequence or list of all possible cards, also known as the deck, and randomly draw from that. otherwise you could end up dealing the exact same card more than once. that'd be awful

I'm pretty sure the code to iterate all the cards already dealt is larger than the size of the deck array would be

Put yourself in my life for a moment: Work is me doing nasty embedded systems bitch work on a tight schedule to make rich people expensive toys, it puts the fear in me that I'll never move past insignificant work with slow microcontrollers.

One day I think: man, wouldn't it be cool to work remotely, travel and live an fulfilling life? Maybe if airport security didn't think my projectos are bombas this could work nicely. Maybe I should look into other tech sub-fields. It's not too unfamiliar that it's scary. I am going to become an interesting person. This will be great. Excitement builds inside me. YOSPOS, kill my dumb dreams.

I work for the only tech company in town and I walk to work somewhere in a nicer part of the (extended) SF bay area. Rent is cheap, house is nice, I live downtown, salary is not good for SF but decent here but my work is meaningless garbage. With these (super) first word problems and no internal direction, what would Y'ALLSPOS do?

7 bytes if you just use bit flags, can't shuffle it but if you're already looping to check for duplicates

you could represent the deck in 6 bytes for dealing the cards, but you'd still need a separate data structure for representing an individual card, or a hand of cards. a single card takes 6 bits, a hand of 2 cards could be represented in 11 bits, a hand of 5 in 22 bits.

profligate wastrel. you can represent the entire game in 52 * log (N + 2) bits where N is the number of players. use bit flags to mark whether each card is in the deck, in the discard pile, or in a given player's hand

I made an Atari breakout clone years ago. the secret trick I had to save ROM space was that when the level was drawn, it was made using background tiles. a row was 8 bits long but 12 bricks wide. the level data was fed from the ROM into the TIA as background tiles so I mirrored the background at exactly the right time that the left third of the level mirrored the right third.

then you do the mirror in software when copying the brick bitfields into RAM and you've saved 24 BITS PER LEVEL of ROM space (6 rows of 8 bricks instead of 6 rows of 12 bricks) and your level fits cleanly into 6 bytes of RAM

I never wrote enough levels for this to make any difference whatsoever because the core game logic was 1.5kb and my compiler did 4kb cartridges anyway

design is hurting my head because i AM making a card game and have my cards neatly made and loaded and everything in the domain with their behavior but they also have to be in the UI for display and they all have the same everything but also exactly one additional attribute in the constructor (the location of the loving card's image) and i really don't like it at all because knowing when to separate logic from UI is retarded and stupid....... sometimes

# ? Oct 5, 2015 22:50

pepito sanchez: Apr 3, 2004; I'm not mexican

the worst part is the game is conga. a game exactly 0.1% of the world play or know. a game i understand but have never played because it's a stupid rear end card game

# ? Oct 5, 2015 22:51

Jerry Bindle: May 16, 2003

don't worry about the API design, how many bytes does the card model consume??

j/k API design is hard. you could implement it using two interfaces: one that deals with the logic, and another that cares about the view. the instances of the concrete class realization of those interfaces would combine the two, but the methods that operated on the logic and the view would be separated.

eh it's all design. it's assumed we already know everything about the language itself already. efficiency is left for the algorithms and data structures class. not a care in the world here, though i know you're joking

but yeah it's both cool and terrifying working with observer and facade and so many other patterns in conjunction for the first time. it's like i worked with mvc by complete accident with c# at this point.

however my one project partner just literally broke his right (good) hand punching a wall out of gayness. so that leaves 4 simultaneous projects almost up to just me and it's slowly creeping up to "a lot of stuff." this is me venting on the yos. i prolly posted that already somewhere but come on. how do you break your loving hand.
