Pipe Game

[Pahanuch]

Hi, all. I have written a game called pipes. You can see this game here http://home.earthlin...rn/pipegame.htm.I did a check for a connection between the pipes. The line of pipes coming from the centre works correctly. But I cant do a check for a disconnection of pipes. When the way to center is broken, others pipes must lost their connection with the center. The code you see below is a check for a connection of central pipes. For object |.

field [i, j].down = 1;
field [i, j].top = 1;
field [i, j].right = 0;
field [i, j].left = 0;

if ((field [i, j - 1].down == 1 && field [i, j].top == 1) && ((field [i, j - 1].flag == false && field [i, j].flag == true) || 
(field [i,j-1].flag == true && field [i,j].flag == false) || (field [i,j - 1].flag == true && field [i,j].flag == true))) {

field [i, j].flag = true;		
field [i, j - 1].flag = true;						                                                                                                                                                                              
cx.Cells [i + 2, j -  1 + 2].BackgroundColor = ConsoleColor.Blue;							 
cx.Cells [i + 2, j + 2].BackgroundColor = ConsoleColor.Blue;}

I attached my game to a topic.
