 Huh
Hi everyone;

I am working on a very simple Solitare Game, fisrtly, i had started with sorting 28 cards into 7 rows and columns. I am using ArrayList to add 28 cards` location on the form.

As you know, solitare game starts with first row delivering 7 cards, then 2nd row delivering 6 cards etc..
Like this:

I am trying to add cards`locations  into ArrayList  exactly like this;

            xTut.Add(50); //1
            xTut.Add(150);
            xTut.Add(250);
            xTut.Add(350);
            xTut.Add(450);
            xTut.Add(550);
            xTut.Add(650);
            xTut.Add(150);
            xTut.Add(250);
            xTut.Add(350);//10
            xTut.Add(450);
            xTut.Add(550);
            xTut.Add(650);
            xTut.Add(250);
            xTut.Add(350);//15
            xTut.Add(450);
            xTut.Add(550);
            xTut.Add(650);
            xTut.Add(350);
            xTut.Add(450);//20
            xTut.Add(550);
            xTut.Add(650);
            xTut.Add(450);
            xTut.Add(550);
            xTut.Add(650);//25
            xTut.Add(550);
            xTut.Add(650);
            xTut.Add(650);//28
            yTut.Add(10);//1
            yTut.Add(10);
            yTut.Add(10);
            yTut.Add(10);
            yTut.Add(10);//5
            yTut.Add(10);
            yTut.Add(10);
            yTut.Add(40);
            yTut.Add(40);
            yTut.Add(40);//10
            yTut.Add(40);
            yTut.Add(40);
            yTut.Add(40);
            yTut.Add(70);
            yTut.Add(70);//15
            yTut.Add(70);
            yTut.Add(70);
            yTut.Add(70);
            yTut.Add(100);
            yTut.Add(100);//20
            yTut.Add(100);
            yTut.Add(100);
            yTut.Add(130);
            yTut.Add(130);
            yTut.Add(130);//25
            yTut.Add(160);
            yTut.Add(160);
            yTut.Add(190);//28

i couldnt figure out an algorithm to calculate this locations like nested for loops or smt.
program works well if i add 28 cards` locations manually, which is not good programming.

i have created yTut and xTut arraylists and tried,


static public void koordinatHesap(){
            xTut.Add(x);
            yTut.Add(y);
            for (int a = 0; a <= 6; a++)
            {
                int x = 50;
                x = a * 100 + x;
                xTut.Add(x);
                for (int b = 0; b <= a; b++)
                {

                    int y = 10;
                    y = b * 30 + y;
                    yTut.Add(y);

                }
            }
        }

but doesnt work, anyone can help me please? Thanks.

How about something simpler, like the following:
1  
2  
3  
4  
5  
6  
7  
8  
9  
10  
11  
12  
public void initialDeal() {
   int board[97];  // only 97 possible board positions (7 columns with 6 face down and 13 face up being the longest column)
  for (int i=0; i<97; i++) {
      board[i] = 0;  // no card yet
  }
   for (int row=0; row<7; row++) {
      for (int col=6; col >=row; col--) {
         boolean faceUp = (col == row);
         board[(row*13)+col] = drawCard(faceUp);  // row 0 is at the top, col 0 is at the left
     }
   }
}
