Card memory game applet.

[Soufly]

Hello, I'm trying to build a card memory game in an 8 by 6 Gridlayout to have 48 cards in total which you have to find the pairs. The cards are in a 2d array which is also 8 by 6. I can get the pairs to appear on the GUI no problem, but the problem is that the pairs appear side by side.

I know that I can just put a button that that does a collection.shuffle, but I want the cards to be shuffled right when the applet starts. The shuffling parts works, but the pairs still stick together, kinda cute if you ask me.

Any suggestions? Please let me if you need more details, thanks in advance!

That seems like a lot of code for what could essentially boil down to

shuffle 2d array
loop i
  loop j
    add item in 2d array at i j to panel
  end loop j
end loop i

Perhaps I am misunderstanding though, please clarify if I am.

Thank you for your reply,

Nah, it's just because of the way I named the cards. like the first ones would be: carte1_01, carte1_02...and so on. Up to carte2_13, thus the weird code with the extra loops. I guess there would be a way to make it simpler, but i just don't know how.

Coming back to the shuffling...I tried doing : listeCartes.add(cartes) which adds my 2d array to the array list which is listeCartes and then did a Collection.shuffle(ListeCartes) but the pairs still appear side by side...Any suggestions?
