    Default A logic / forloop question

    This is another portion of the same program referenced earlier. It's sort of like tic tac toe, but with a variable board size. I have already gotten my method for checking to see if anyone has a tic tac toe to work, but currently I have a different method for each board size, and each player, which gets really really long. I know there must be a way to only do it once. I was thinking nested forloops, but it doesn't seem to work with the logic I am using, as the x and y increment together. Some tips would be great. I need this to work for any board size, and check horizontal, vertical and diagonal win possibilities.
    	/** Checks the board to see if the player has scored any points by filling a row, column or diagonal with their pieces. If so,
    	 * player is awarded points for each space filled and pieces are removed from the board. @param gameBoard. @return gameBoard.
    	 * 
    	 */
    	public static int[][] checkBoard3Player1(int[][]gameBoard)
    	{
    		boolean[] rows = new boolean[gameBoard.length];
    		for(int x = 0; x < gameBoard.length; x ++){
    			if(gameBoard[x][0] == gameBoard[x][1] && gameBoard[x][0] == gameBoard[x][2] && gameBoard[x][0] != 0)
    				rows[x] = true;
     
    		}
    		boolean[] cols = new boolean[gameBoard.length];
    				for(int y = 0; y < gameBoard.length; y++)
    				{	if(gameBoard[0][y] == gameBoard[1][y] && gameBoard[0][y] == gameBoard[2][y] && gameBoard[0][y] != 0)
    						cols[y] = true;
    				}
    		boolean diagLtoR = false;
    				if(gameBoard[0][0] == gameBoard[1][1] && gameBoard[0][0] == gameBoard [2][2] && gameBoard[0][0] != 0)
    					diagLtoR = true;
    		boolean diagRtoL = false;
    				if(gameBoard[0][2] == gameBoard[1][1] && gameBoard[0][2] == gameBoard [2][0] && gameBoard[0][2] != 0)
    					diagRtoL = true;
     
    		for(int x = 0; x < rows.length; x ++)
    		{
    			if(rows[x])
    			{
    			for(int gbi = 0; gbi < gameBoard.length; gbi ++)
    				{
    				gameBoard[x][gbi] = 0;
    				player1Score++;
    				}
    			}
    		}	
    		for(int y = 0; y < cols.length; y ++)
    		{
    			if(cols[y])
    			{
    				for(int gbi = 0; gbi < gameBoard.length; gbi ++)
    				{
    				gameBoard[gbi][y] = 0;
    				player1Score++;
    				}
    			}
    		}
    			if(diagLtoR)
    			{
    			gameBoard[0][0] = 0;
    			gameBoard[1][1] = 0;
    			gameBoard[2][2] = 0;
    			player1Score++;
    			}
    			if(diagRtoL)
    			{
    			gameBoard[0][2] = 0;
    			gameBoard[1][1] = 0;
    			gameBoard[2][0] = 0;
    			player1Score++;
    			}	
     
    		return gameBoard;
    	}

    Default Re: A logic / forloop question

    As It's your design process, It's kind of hard to comment, but I'd recommend you go with a more object oriented approach, by splitting the logic into multiple classes, such as 1 that defines a player, his score, how to check his score and say another class that defines the board.

    Obviously that was a very vague answer, but where others may easily be able to interpret what you're doing, I'm not quite with you

    Default Re: A logic / forloop question

    Thanks Newbie, you're right about the object design. My original game was all in one class, which was a bit of a monster.

    I have seperated it into appropriate classes now, and want to move this method into the board class as well. I will modify it for that.

    All I am really asking is how to check each portion of the board without having to have a different method for each board size.

    for example,
    3x3 board
    5x5 board

    want logic to check both for having tic tac toe win, without having 2 differnt methods.
