I need a nested array please

[roofy]

Hi there all, its me again, the pain in the neck :)
Our final project is coming up and I thought of the game called Memory. The object of the game is there will be 16 cards in a 4 cards across and 4 cards down giving me a 4x4 col/row table. The user will click on 2 different cards one at a time, and if there is a match between the 2 clicked on cards then the matched cards will be moved to the collection pile. When the user has collected all 8 pairs then the user wins.

Now the easist way I could think of doing this would be to build a nested array. So I wanted to know if it is possible to create nested array's in Alice. I know you can do it in standard C, but I have the faintest idea how I would do this in Alice. However, if I can not create nested array's then how would I go about building a 4x4 col/row setup?

When I started on the Christmas puzzle I posted a few days ago, I was going to use the same approach - but never really figured out how to do a multi-dimensional array in Alice. (Frankly, I didn't try too hard. ;) )

Instead, I went to a simple list and didn't worry about the x-y placement, which was fine for the puzzle, since I eventually wanted to be able to use it with an arbitrary array size.

You might try the same thing with a list of 16 cards and the index also corresponding to a card position (defined in the initial setup). Then the same loop that would check to see if you clicked on a card could also check to see if the previous card checked on was the same type. (I know this is a bit brief, but see the code for the puzzle if you want to try it.)

If you do stay with the array approach, please post the result. :) I'd really like to see a good example of that method.

Dr. Jim,
I have not forgotten you. I have been busy as a bee with my last project. I will have my file uploaded this afternoon with comments in my code

I would put up my file for people to look at and see how the code works, but I have a nasty bug that I cannot seem to figure out because sometimes the program works and other times it does not. However, when it does not work, Alice spits out a runtime exception error when it is checking to see if the 2 textureMaps match. Has anyone have this type of problem?
