@kendog400 There are plenty of card game examples on the forum. Do a forum search to see what you can find.

@kendog400 Here’s a start for your card game. Some code to create a deck of cards. You can alter this to create what you want.

supportedOrientations(LANDSCAPE_ANY)
displayMode(FULLSCREEN)

function setup()
    rectMode(CENTER)
    creatDeck()
end

function draw()
    background(207, 228, 211, 255)
    for value=1,13 do
        for suit=1,4 do
            sprite(cards[suit][value],value*70,HEIGHT-suit*150)
        end
    end
end

function creatDeck()
    cards={}
    local pic={"??","??","??","??"}
    local val={"2","3","4","5","6","7","8","9","10","J","Q","K","A"}
    for s=1,4 do
        cards[s]={}
        for v=1,13 do
            img=image(50,70)
            setContext(img)
            fill(255)
            stroke(0, 235, 255, 255)
            strokeWidth(3)
            rect(25,35,50,70)  
            sprite("SpaceCute:Star",25,35,75)
            fontSize(13)
            text(pic[s],12,57)
            text(pic[s],38,13)
            fill(255,0,0)
            fontSize(25)
            text(val[v],25,35)
            setContext()
            cards[s][v]=img
        end
    end
end

Thank You…

@kendog400 Here’s a version based on what you show above. It’s a total waste of Codea’s capabilities, but it can be done. Press “h” for hit, “s” for stay, and “a” to play again. It’s in portrait mode and you should slide the output window all the way up to show all of the print statements. I think it runs without errors, but I didn’t test it that well.

EDIT: Made minor change for dealer.

supportedOrientations(PORTRAIT_ANY)

function setup()
    showKeyboard()
    output.clear()
    player,dealer={},{}
    for z=1,2 do
        table.insert(player,math.random(11))
        table.insert(dealer,math.random(11))
    end   
    showPlayer(1)
end

function draw()
    background(0)
    fill(255)
    if ans=="s" then
        output.clear()
        showDealer()
        showPlayer(2)
        showWinner()        
    elseif ans=="h" then
        output.clear()
        table.insert(player,math.random(11))
        showPlayer(1)
    elseif ans=="a" then
        setup()
    end
    ans=""        
end

function showDealer()
    dealerSum=0
    for a=1,#dealer do
        dealerSum=dealerSum+dealer[a]
    end
    while dealerSum<17 do
        dealerSum=0
        table.insert(dealer,math.random(11))
        for a=1,#dealer do
            dealerSum=dealerSum+dealer[a]
        end
    end
    print("The dealer has a total of "..dealerSum)
    print("from these cards "..table.concat(dealer," "))
end

function showPlayer(a)
    playerSum=0
    for a=1,#player do
        playerSum=playerSum+player[a]
    end
    print("You have a total of "..playerSum)
    print("from these cards "..table.concat(player," "))
    if playerSum>21 then
        showWinner()
    elseif a==1 then
        print("\
\
Do you want to stay(s) or hit(h)") 
    end   
end

function showWinner()
    if playerSum>21 then
        print("Dealer wins!")
    elseif dealerSum>21 then
        print("You win!")
    elseif playerSum>dealerSum then
        print("You win!")
    else
        print("Dealer wins!")
    end
    print("Play again?(a)")
end

function keyboard(k)
    ans=k
end

This is a snapshot picture, notice the Royality Image (Queen). This will be replaced with the picture of the card suit…

@kendog400 You have the correct logic, but some of your values are wrong. Here’s an updated version.

    if numAces==1 then
        if myValue+11>21 then
            myValue=myValue+1
        else
            myValue=myValue+11
        end
    elseif numAces==2 then
        if myValue+12>21 then
            myValue=myValue+2
        else
            myValue=myValue+12
        end
    elseif numAces==3 then
        if myValue+13>21 then
            myValue=myValue+3
        else
            myValue=myValue+13
        end
    elseif numAces==4 then
        if myValue+14>21 then
            myValue=myValue+4
        else
            myValue=myValue+14
        end
    end

@kendog400 You’re missing code. The above code has errors.

@kendog400 When you post code, use ~~~ before and after your code. You’re missing code at the end of the card class and you have errors in the other code.

self.suits={“??”,”??”,”??”,”??”} Not sure what’s happening. I thought maybe you couldn’t show the emojis, but they work for me.
