Card geme : Acey-Ducey, stuck on line 153, repeat is wrong word,
Can anyone help ? Heres the code below

“repeat” isn’t a Lua keyword. You can use while(condition) .... end for a loop loop. If condition is false, it will skip running the loop and move on. If condition is always true, it will run until it his a break.

@kendog400 Anytime you post code, put 3 ~'s on a line before and after the code so it shows correctly.

dave1707 · July 21, 2017, 8:28pm

@kendog400 Where did you get the code from. It looks like you copied it from somewhere and you think it’s going to work in Codea. There’s a lot of things in the above code that isn’t going to work.

dave1707 · July 21, 2017, 9:43pm

@syntonica repeat is valid. Try this code.

function setup()
    a=0

    repeat
        a=a+1
        print(a)
    until a>15

end

syntonica · July 22, 2017, 1:03am

Ack! Sorry about that to the OP. Repeat/until will run at least once while a while may never run.

I never use repeat/until since I never need it.

kendog400 · July 22, 2017, 5:40pm

Yes, I copied it from a site on-line, I would like to program Card Games, so it is part of a study until I get my roll on…

kendog400 · July 22, 2017, 5:44pm

The card Game was written LUA, but I see now that, it doesent mean it would work in Codea…In any event Thanks for the Help !

dave1707 · July 22, 2017, 5:47pm

@kendog400 Do a forum search for cards games. You might come up with some interesting things.

dave1707 · July 22, 2017, 7:59pm

@kendog400 If you want to play with card games, maybe this would help some.

function setup()   
    rectMode(CENTER)
    suit={"??","??","??","??"}
    val={"2","3","4","5","6","7","8","9","10","J","Q","K","A"}    
end

function draw()
    background(40, 40, 50)
    cnt=0
    for x=1,4 do
        for y=1,13 do
            cnt=cnt+1
            card(x*100,y*70,cnt,1)
        end
    end
end

function card(x,y,v,sc)      -- x,y position    Card value 1 to 52   sc=size of card
    scale(sc)
    local c=(v-1)%13
    local s=(v-1)//13+1
    fill(255)
    stroke(0, 255, 182, 255)
    strokeWidth(3)
    rect(x,y,45,60)
    fill(255,0,0)
    if s<3 then
        fill(0)
    end
    fontSize(25)
    text(val[c+1],x,y)
    fontSize(14)
    text(suit[s],x-10,y+18) 
    text(suit[s],x+10,y-18) 
    scale(1/sc)
end

It looks like this was designed for a Lua compiler running on windows platform and was not programed for Codea.

xThomas · October 27, 2017, 10:00am

Ok, first off, i looked at the original page you got this code from. You’re missing this line until doneat the end of the script. happened to me when i copied it too.

second, it still won’t run - not toally sure why, but i think (just a theory) that Codea won’t allow you to run a script if there’s a repeat or while loop that hasn’t finished running. when you do try, it disables the play button and the extra features on the keynoard as well, so maybe a bug there

so replace the repeat, until with function draw() if not done then --[[ the code already there ]] else return end end

xThomas · October 27, 2017, 10:49am

ok, so i did that, now im having issues adapting the io read write etc. the real trick is going to be getting io.read to work.

local amount = io.read();

See, what i want is for io.read to bring up the keyboard, but the repeat loop keeps going. so… ill need to rewritr everything >:(

edit: i give up. this is too hard to convert into codea

kendog400 · October 27, 2017, 1:58pm

I would like to see more youtube type tutorials for codea. Programming isn’t for the faint at heart and it takes a lot of brain power… 3d max, cinema 4d, zbrush, photoshop all have large followings, and a large amount of youtube tutorials. I would like to see codea with this type of enviorment.

xThomas · October 27, 2017, 8:19pm

@kendog400 I never liked video tutorials myself. for something like photoshop or krita i can see why it is useful, but when programming i really prefer to have a reference guide in another phone or book while i code. Actually,learning it myself, I still have’t gone into the new Craft stuff yet or even figured ot physics - busy learning everything else.

Hm… Checklist of what you know? This stuff is lua that I think would be nice to know

What ‘Dynamically typed’ means. >! Lua is dynamically typed, which means that you can say t={}; and then later say t=‘string’. Variables aren’t locked to their type. !<
Given t={a=false,b=false}, set every false value to true using a for loop
How to use a while condition ... do loop
What conditions evaluate as true, and what are false. >! Any value that isn’t explicityly false or nil is true. An empty string or tsble evaluates as true.
A repeat .. until loop >! Will always run at least once, it runs first, then checks if condition is true or false, whereas a while loop checks condition first, and so might never run.
What tail calls are. >! Sorry, you’re on your own here.
A recursive function >! basically a function that calls itself. e.g. function f(x) return x<10 and f(x+1) or x end print(f(1));
Short circuit logic. VERY useful thing I didn’t know until recently. i.e. >! x=1; x = x==2 and 3 or 0; So this is the same as if x==2 then x = 3; else x = 0; endbut easier to write. if you didn’t include the ‘or 0’ then it would be by default false’, because the or part only runs if the ‘condition’ is untrue
multiple assignment. can you guess what this prints? local a,b,c = 1,2; print(a,b,c) >! 1,2,nil
How to write your own iterator function. You know how for loops call psirs, or ipairs? these sre actual functions and you can write your own

@kendog400 Here’s my above code with a few modifications to shuffle a deck of cards. My suggestion is to look over this code and try to understand what’s happening. That’s an easy way to learn.

displayMode(FULLSCREEN)
supportedOrientations(PORTRAIT_ANY)

function setup()   
    rectMode(CENTER)
    suit={"??","??","??","??"}
    val={"2","3","4","5","6","7","8","9","10","J","Q","K","A"}  
    deck={}
    shuffle()
end

function draw()
    background(40, 40, 50)
    fill(255)
    text("Tap screen to shuffle",WIDTH/2,HEIGHT-50)
    cnt=0
    for x=1,4 do
        for y=1,13 do
            cnt=cnt+1
            card(x*100,y*70,deck[cnt],1)
        end
    end
end

function touched(t)
    if t.state==BEGAN then
        shuffle()
    end
end

function shuffle()
    local tab={} 
    for z=1,52 do
        table.insert(tab,z)
    end
    deck={}
    for z=1,52 do
        d=math.random(#tab)
        table.insert(deck,tab[d])
        table.remove(tab,d)
    end   
end

function card(x,y,v,sc)      -- x,y position    Card value 1 to 52   sc=size of card
    scale(sc)
    local c=(v-1)%13
    local s=(v-1)//13+1
    fill(255)
    stroke(0, 255, 182, 255)
    strokeWidth(3)
    rect(x,y,45,60)
    fill(255,0,0)
    if s<3 then
        fill(0)
    end
    fontSize(25)
    text(val[c+1],x,y)
    fontSize(14)
    text(suit[s],x-10,y+18) 
    text(suit[s],x+10,y-18) 
    scale(1/sc)
end

Thank You for the help…
