how would i make a proc that would take a stack of objects and shuffle them?

What the heck do you mean "shuffle them"?
Generally, you can get a randomized result by using rand(), pick(), etc. If you are trying to simulate cards, I suggest you just assign them to a list, use pick to select them (when drawn or whatever), the move the "card" out of the list.

Mix them up.

Um, well, if you follow Jmurph's advice, you'll find that is probably what you need. No need to mix up the list of cards, just have the pick() select a card at random. Then remove that card from the list so it won't be picked agian. Pretty straightforward if you ask me....

then i would have to pick what cards would be in the list, but I want the cards in the list to be randomly generated. Oh Well.

proc/Shuffle(list/cards)
  var/card
  for(var/i=cards.len,i>1,--i)
    var/j=rand(1,i)
    card=cards[j]
    cards.Cut(j,j+1)
    cards+=card

That ought to do the trick.

That would be a seperate operation alltogether. I assumed that you had a set deck, like in Una, or Spades, or whatever...

But if you are using dynamic decks (like in Magic, etc...) Then you'll need to make a proc to add the individual cards to the list. I suppose you could make another list for this proc to pick from, and simply re-use the first proc to do both things, create the deck, and randomly give out cards from that deck...

It all depends on how your game is going to behave. I was simply pointing out that the advice given to you previously was valid, and should (with perhaps slight alterations) do what you need it to.

So like under
obj
card
monster
New()
list+=monster

is that the idea?

The list would represent the deck. For normal playing cards, the deck isn't random--the same 54 cards are always in there. See LummoxJR's example in this thread.

On the other hand, if you're trying to do a CCG, you just build a random deck out of master lists of common/uncommon/rare cards.
