Thread: Connect Four FAIL....

Lab 7 - #2

Implement a Connect 4 game. The program should allow two players to play each other. For each turn, have the user enter the column they want to play in, validate the user has made a good move, and then place the piece on the board. Then the program should check for a winner and a tie, and assuming there is neither, redisplay the board and get the next players move. Display the moves using print/printf/println commands, and use an X for player 1 and an O for player 2. When the game ends, the program should display congratulations to the winner or announce there was a tie, and then allow the players to choose to play again or exit.

You must use a 2D array for this lab.


I believe i am on the right track but i am getting lost, any help would be so appreciated.

import java.util.Scanner;
public class Lab7
{
	public static void main(String args[])
	{
		// create board
		int cFBoard[][] = new int[7][8];
		Scanner input = new Scanner(System.in);
		//loop
 
 
			//init board
 
 
			// currentPlayer = 1, numMoves = 0;
			int cPlayer = 1;
			int pAgain;
			int nMoves=0;
 
 
			//LOOP
 
			// display board
			System.out.println("\t1\t2\t3\t4\t5\t6\t7");
 
			for (int r = 1; r <= 6; r++)
			{
				System.out.print(r);
 
				for(int c = 1; c <= 7; c++)
				{
					System.out.print("\t" + cFBoard[r][c]);
				}
					System.out.println();
			}
 
				int c;
 
			// get move
			do
			{
 
					System.out.print("Input desired column: ");
					  	C = input.nextInt();
 
			}
			while (c < 1||c > 7|| cFBoard[6][c] !=0);
 
 
 
 
			// place piece
 
 
			for(int r = 1; r<=6; r++);
			 {
 
				if (cFBoard[r][c]==0)
				{
 					cFBoard[r][c] = cPlayer;
 					playerConvert();
 
				}
 
			 }
			//Check winner
	}
}
 
 
class playerConvert
{
public String convert(int cPlayer)
		{
			if (cPlayer == 1)
			{
				return "X";
			}
			else if (cPlayer == 2)
			{
				return "O";
			}
			else
			{
				return "-";
			}
		}
}

I even have these notes but i am still lost.

Lab 7 notes

 
ALGORITHM
// create board
// LOOP	
	// init board
	// currentPlayer = 1, numMoves = 0;
	LOOP UP TO 42 TIMES
		// display board
		// get move (includes validation)
		// place piece
		// check winner
		// check tie
		// change currentPlayer
	END LOOP
	// Display congratulations/tie
	// do you want to play again
// END LOOP
 
DATA NEEDED
Int board[][]
Int currentPlayer
bool playAgain
int numMoves
 
GAME BOARD
int board [] [] = new int[7][8]	
Using rows 1-6 and columns 1-7 and ignoring element 0
 
	1	2	3	4	5	6	7
6	6,1	6,2	6,3	6,4	6,5	6,6	6,7
5	5,1	5,2	5,3	5,4	5,5	5,6	5,7
4	4,1	4,2	4,3	4,4	4,5	4,6	4,7
3	3,1	3,2	3,3	3,4	3,5	3,6	3,7
2	2,1	2,2	2,3	2,4	2,5	2,6	2,7
1	1,1	1,2	1,3	1,4	1,5	1,6	1,7
 
DISPLAYING BOARD
See the last in class problem
 
 
CONVERT ROUTINE
public String convert(int i)
{
	if (I == 1)
{
		Return “X”;
}
	else if (I == 2)
{
		Return “O”;
}
	else
{
		Return “-”;
}
}
 
VALIDATE MOVE
do
{
// get move
}
while (col < 1 || col <> 7 || board [6][col] != 0);
 
PLACEMENT
for(int i = 1; i<=6; i++);
 {
	if (board[i][col]==0)
	{
		board[i][col] = current player;
		break;
	}
 }
 
HORIZONTAL CHECK FOR WIN
for (int r = 1; r < = 6; r++)
{
    for int c = 1; c <=4; c++)
	    {
 	        if (board [r][c] == board [r][c+1] && 
board[r][c+1] == board[r][c+2] &&                                        
board[r][c+2] == board[r][c+3] && 
              board[r][c] != 0)
        {
              win = true;
         }
     }
}

I dont have a specific question, there is to many to ask. I have no idea how to do this.... i was fine with if statements and loops. but as soon as i go to arrays i loose it all.
