I need a nested array please

**I need a nested array please -** 12-06-2006, 03:25 AM

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?
