2d array for board game

Hey guys.

Not sure if im on the correct forum but anywho...im using c# with XNA to create a 2D board game.

Ive used a tile engine to draw the images of each tile(to make up the entire board) to the screen.

Now im trying to create a 2D array(below) to depicate the actual board

Do I have to initialize the array and go through each tile on the board(with all the 0's)

int[,] myArray = new int[10,5];

int[,] myArray = new int[,] {{0,0,0,0,0}, {0,0,0,0,0}, {0,0,0,0,0}, (0,0,0,0,0}, {0,0,0,0,0}, {0,0,0,0,0}, {0,0,0,0,0}, (0,,0,0,0,0},{0,0,0,0,0}, {0,0,0,0,0}};

PrintArray(myArray);

public class ArrayClass
{
   static void PrintArray(int[,] w)
   {
      // Display the array elements:
      for (int i=0; i < 10; i++)
         for (int j=0; j < 5; j++)

//is the below line correct?
            Console.WriteLine("Element({0},{1})={2}", i, j, w[i,j]);
   }

   public static void Main()
   {
      // Pass the array as a parameter:
      PrintArray(new int[,] {{0,0,0,0,0}, {0,0,0,0,0}, {0,0,0,0,0}, (0,0,0,0,0}, {0,0,0,0,0}, {0,0,0,0,0}, {0,0,0,0,0}, (0,,0,0,0,0},{0,0,0,0,0}, {0,0,0,0,0}};
   }
}

P.S how do i post code properly on this site?

Thanks in advance for any replies.

John

Accepted answer
When you create an int array, all its elements are set to zero by default so, if that's all you want to do, there's no need to initialize it. The following should work fine:

using System;

public class ArrayClass
{
static void PrintArray(int[,] w)
{
// Display the array elements:
for (int i=0; i < 10; i++)
for (int j=0; j < 5; j++)
Console.WriteLine("Element({0},{1})={2}", i, j, w[i,j]);
}

public static void Main()
{
int[,] myArray = new int[10,5]; // all elements zero by default
// Pass the array as a parameter:
PrintArray(myArray);
Console.ReadKey();
}
}

I always post code as plain text. As long as it's suitably indented, it's easy enough to read :)

Yes, that's how you'd normally create a List and add elements to it.

As far as the articles are concerned if you have a question, then you need to ask this in the comments to the article.

Hopefully, the author will see it and reply but if not you could try sending him/her a message directly via the site.

Thats great vulpes. thanks again for the info although i was looking at the http://www.c-sharpcorner.com/1/200/xna.aspx section
and i can only see places to post an article and other stuff but no place to ask a question...im probably just blind lol?.

I was going to ask though...i was thinking of creating a list
and the index of each piece can be stored in the 2d array.(how yet i am unsure) but for the time being if i was to create the list to store each details of each tile on the board.E.g

List<pieces> list = new List<pieces>();
list.Add(letter);
list.Add(score);

does this look ok?
please advise...thanks again...

When you use Console.WriteLine, stuff like {0}, {1} and {2} included in the first argument are placeholders which are filled by the values in the second, third and fourth arguments respectively.

So, {0} gets replaced by i, {1} by j and {2} by w[i,j] and you end up with a line like:

Element(0,0)=0

Sorry, I'm no help on XNA though we do have a large number of articles about it on this site:

I'd wait and see if you get more answers on here and, if you don't, repost the question on one of the specialist XNA forums.

aww thats great, thanks vulpes, its easy when you see it wrote infront of you.
I see the print array method goes through the array and writes the line but what does the piece of code ("Element({0},{1})={2}", i, j, w[i,j]); at the end of the print array method do?

Yeah i want to set all the elements of the int array to 0 at the beginning (as the board will have no letters placed on it yet)

As I said im trying to write a 2d board game using XNA. would you be able to offer any advice on what to do next.

Each image of the seperate tiles are displayed on screen using a tile engine to make up the physical appearance of a board.
10001
01010
00100
01010
10001

At the minute the user can drag and drop letters onto the board.(but its display purposes at the minute) How can I map the array(you have just shown me) to the board.

So when a user drops a letter on a tile it will store the 'letter' in the array?

thanks again
