Help with Tic Tac Toe game.

I have finished my entire game excpet for who wins. Anyone have some insight on how to do this?

private boolean isRow(char arr[][],char s)
        for (int i=0;i<3;i++)
            if (arr[0]==arr[i][1] && arr[i][1]==arr[i][2])
if (arr[i][0]==s)
return true;
if the condition if (arr[0]==arr[i][1] && arr[i][1]==arr[i][2]) was false so return true; won't work, and so the method is left without a return value.
you can solve the problem by modifying this code to this:
private boolean isRow(char arr[][],char s)
        for (int i=0;i<3;i++)
            if (arr[0]==arr[i][1] && arr[i][1]==arr[i][2])
if (arr[i][0]==s)
return true;
return false;

  • Need some help with Tic Tac Toe game

    hey. hope u guys can help me out...
    having a problem with my tic tac toe program...
    i have 2 problems.
    1) got the "X" and "O" to appear using a flag(teacher didn't explain)
    using code like this
    if (jb == button[0]){
    if (flag==0)
    button[0].setText("X");
    else
    button[0].setText("O");
    //toggle
    flag = (flag==0)?1:0;
    my problem is how do i get it to stop.(For example button[1] is selected as "X"..how do i stop it from albe to switch to "O")
    2) found this code in javascript online and i want to do what it does in java code
    if(button[0] == " X " && button[1] == " X " && button[2] == " X ")
    alert("You Win!");
    reset();
    how would i do that?

  • Need help/advice with tic tac toe game

    Hello all. I am working on a tic tac toe game. I was able to program the first 4 moves fine, but ame having trouble with moves 5 and 6 for reasons that are unknown to me. Everything complies fine, its just that the move is displayed int the wrong space (B1) instead of in B2 or B3. Also the move that is supposed to be in A1 disapppears when B2 or B3 is clicked. Also, I need advice as to how to keep the prior moves from being over written.
    At this point I ahve gone over the code on-screen, printed it out, and stared at my drawings... and I'm not having any luck. I'm sure its a small, stupid thing that I'm missing, that anyone else would easily catch. Once again, thx for all your help.

    writing a tic-tac-toe is harder than it sounds.. i wrote one last year in my computer science class.. i have it on my website, if you want to look at code. i wrote it in c++, but the logic is all that matters :)
    btw-last year, i wasnt too good of an OOP programmer, so the program is procedurely written. heres the url:
    http://www.angelfire.com/blues/smb
    also, to tell if a box is already taken, you can just add an if statement:   if ( gameBoard[selX][selY] == null )  //not taken, fill box:many people resort to a boolean matrix of the same idea, but with booleans that store which boxes are taken. i prefer the way above, saves code, memory, and makes it more understandable.
    hope it helps.

  • Help with tic tac toe

    hey all,
    i am having problems creating a tic tac toe program. the program should create a board with NxN spaces, where N is obtained through user input.
    I created a fully working program that does a 3x3 board, checks for diagonal, vertical, horizontal wins and also allows 1 vs computer or 2 players play, but i am struggling with the NxN board.
    here is the code of what i have, can anyone point me in the right direction? all help is appreciated! please keep it simple as possible as i am just learning java!!

    well, i figured out how to do it all, thanks to the TREMENDOUS amount of help here...lol...
    i just have one more (minor problem)...
    i can't get an algorithm working to see if the two diagonals are occupied by x's or o's (see if someone won diagonally)
    to check horizontally & vertically on an NxN board, i use following code:
    int count = 0;
            /** check horizontally  */
            for (int i = 0; i < myBoard.length; i++)
               for (int j = 0; j < myBoard.length-1; j++)
                   if (myBoard[0].equals(myBoard[i][j+1]) && !myBoard[i][0].equals(EMPTY))
    count++;
    if (count >= myBoard.length-1)
    return myBoard[i][0];
    count = 0;
    count = 0;
    /** check vertically */
    for (int i = 0; i < myBoard.length; i++)
    for (int j = 0; j < myBoard.length-1; j++)
    if (myBoard[j][0].equals(myBoard[j+1][i]) && !myBoard[0][i].equals(EMPTY))
    count++;
    if (count >= myBoard.length-1)
    return myBoard[0][i];
    count = 0;
    now i was messing around ALOT and couldn't figure out how to get the diagonals showing! this is what i came up with:
    count =0;
    for (int j = 1; j < myBoard.length; j++)
           if (myBoard[0][0].equals(myBoard[j][j]) && !myBoard[0][0].equals(EMPTY))
                 count++;
                 System.out.println(count);
            if (count >= myBoard.length)
                 return myBoard[0][0];
    count = 0;
    for (int j = myBoard.length-1; j >= 0; j--)
         if (myBoard[0][myBoard.length-1].equals(myBoard[j][j]) && !myBoard[0][myBoard.length-1].equals(EMPTY))
             count++;
             System.out.println(count);
          if (count >= myBoard.length)
              return myBoard[0][myBoard.length-1];
          count = 0;

  • Help with Tic Tac Toe program....

    I am writing a tic tac toe program, and I have already put the 9 boxes onto the screen so that it looks like the Tic Tac Toe board.
    My first box looks something like this:
    Rectangle2D.Double box1 = new Rectangle2D.Double(0, 0, 100, 100);
    g2.draw(box1);
    I want assign a number to the 9 boxes so it looks like this:
    123
    456
    789
    And I want to know how am I suppose to assign a number to a box, so that when the number is pressed it will put an "X" or "O"(depending on whose turn it is).
    P.S. If you already made a Tic Tac Toe progaram can you post it so I will have an idea of what you did. thx.

    I'd hate to post the whole thing, but if you don't have access to it, here it goes:

  • Tic - Tac - Toe Game - Please Help!

    Hi everyone, I am attempting to create a tic - tac - toe game (O's & X's).
    I would like there to be two playing modes to the game, the first mode will be one player where the user plays against the computer. The second mode is a two - player game, where two users play, one being X's and the other being O's.
    Can anyone help me get started with this game, I know there is source code on the internet but I would rather not use this as I would like to learn as I create the game.
    Thanks Everyone

    its amazing how much code a simple game like tic-tac-toe can require.. well, only if you program the AI of the computer.. i wrote one in c++ last year, for my computer science class, and the whole class had trouble with it, mainly the AI.. a suggestion to you: write it in an object-oriented manner. i ended up writing it procedurally and in the end, it looked very bad, but it worked!
    i would prob. setup some objects like: Board (the 3x3 grid), Mark (a user mark, such as an "x" or an "o")..
    i dunno.. hope that helps some, if you need help with the AI at all.. i do have the tic-tac-toe program i wrote on my website (http://www.angelfire.com/blues/smb/ ) in the C++ section.. i used a graphics package, but the logic is all there and the code is well commented.
    anyway, ill talk to ya later, good luck,

  • Tic Tac Toe game using Graphs

    Does anyone know of an open-source implementation of Tic-Tac-Toe using Graphs? I'm reading through Michael Mann's Data Structures and Other Objects Using Java book and in chapter 14, he briefly mentions the use of directed graphs in implementing a game of Tic Tac Toe. I'm interested in seeing how one would implement something of this sort (and no, it's not a homework assignment).
    If someone would be kind enough as to post a link to a site that offers mini-java applications, along with code that novice developers such as myself can traverse, please do so.
    Thanks in advance.

    As an added though, there's really no need to for each node to keep track of incoming connections, only outgoing ones. What I, personally would do is keep an array of 8 outgoing connections, one for each direction. If no connection was there, then that element in the array would be null. If a connection was there, then that element would be an edge connecting to another node, or the other node itself (depending on whether or not you explicitly implemented 'edges' in your graph).
    That way, you could do something like:
        Node    s         = getOneOfTheEdgeNodes();
        boolean hasWinner = false;    
        try {
            for (int i = 0; i < 8; i ++) {
                if (s.getOutgoing(i).getNode().getOutgoing(i).getNode() != null) {
                    hasWinner = true;
                    break;
        } catch (NullPointerException npx) {
            // No winner.
        if (hasWinner)
            System.out.println(s.getPlayer() + " has won");Yeah, that's a shitty example, but hopefully you get my drift.

    I know this is suppose to be a real java forum, but this is stripped down version of java, but it's still java. Before using real java I used this Judo.

  • Help in swing app. tic tac toe

    Trying to make this tic tac toe game. Need a little help. I want the newGameBUT to start the game over, and I would like turnTF to display if a tie occurs. (I tried using *if button.enabled(false) {* but it didn't work. If anyone could help me out, that'd be great. Oh, also, the new game button currently add's 1 to whoever won so far, which is really weird =x. Thanks beforehand.

  • Tic tac toe 3x3 multiplaye​r game

    How can i build a tic tac toe game in labview
    What im interested in is the following
    1) A 3x3 multiplayer game
    2) A boolean to move left in the tictactoe grid and another to move down
    3) A boolean array to display the grid an another string array to show the X and O's
    4) A boolean to confirm player's choice
    5) A way to choose whether player 1 or player 2 begins
    6) A way to show which player wins or loses, or if it is a draw.
    Thank You in Advance
    I appreciate your help 

    Some of your classmates with the same assignment already asked this quesiton. Why don't you do a quick search before starting a new thread?

  • Tic Tac Toe with AI

    Well I'm getting ready for my second semester of Java programing and I figured I would try and get back in the swing (no pun intended) of things by creating a simple tic tac toe game. I was able to make a two player game with in a matter of hours so I figured I would try and make a one player game with AI and thats where im having some issues. Here is my code for two person tic tac toe
    package mytictactoe;
    import java.awt.*;

         /*Instance Variables*/
         private int[][] winCombinations = new int[][] {
                   {1, 2, 3}, {4, 5, 6}, {7, 8, 9}, //horizontal wins
                   {1, 4, 7}, {2, 5, 8}, {3, 6, 9}, //virticle wins
                   {1, 5, 9}, {3, 5, 7}                //diagonal wins
         private JFrame window = new JFrame("Tic-Tac-Toe");
         private JButton buttons[] = new JButton[10];
         private int count = 0;
         private String letter = "";
         private boolean win = false;
         public TicTacToeV2(){
         /*Create Window*/
         window.setSize(300,300);
         window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
         window.setLayout(new GridLayout(3,3));
         /*Add Buttons To The Window*/
         for(int i=1; i<=9; i++){
              buttons[i] = new JButton();
              window.add(buttons);

         window.setVisible(true);
         public void actionPerformed(ActionEvent a) {
              count++;
              /*Calculate whose turn it is*/
              if(count % 2 == 0){
                   letter = "O";
              } else {
                   letter = "X";
              /*Write the letter to the button and deactivate it*/
              for(int i=1; i<=9; i++){
                   if(a.getSource() == buttons[i]){
                        buttons[i].setText(letter);
                        buttons[i].setEnabled(false);
              /*Determine who won*/
              for(int i=0; i<=7; i++){
                   if( buttons[winCombinations[i][0]].getText() == buttons[winCombinations[i][1]].getText() &&
                        buttons[winCombinations[i][1]].getText() == buttons[winCombinations[i][2]].getText() &&
                        buttons[winCombinations[i][0]].getText() != ""){
                        win = true;
              /*Show a dialog when game is over*/
              if(win == true){
                   JOptionPane.showMessageDialog(null, letter + " wins the game!");
                   System.exit(0);
              } else if(count == 9 && win == false){

         public static void main(String[] args){
              TicTacToeV2 starter = new TicTacToeV2();
    Now for my program with AI I'm essentially using the same code and just for clarity I removed all the code that determines who won (as it isnt needed to get the AI to work) This is what I have so far

         public void actionPerformed(ActionEvent a) {
              count++;
              /*Write the letter to the button and deactivate it*/
              for(int i = 1; i<= 9; i++){
                   if(a.getSource() == buttons[i]){
                        buttons[i].setText("X");
                        buttons[i].setEnabled(false);
              AI();
         public void AI(){
              Random x = new Random();
              int y = 1 + x.nextInt(9);
              if(buttons[y].getText() == "X" || buttons[y].getText() == "O" ){
                   AI();
              } else {
                   buttons[y].setText("O");
                   buttons[y].setEnabled(false);
         public static void main(String[] args){
              new TicTacToeV3();
    It kind of works because each time i choose a box the "computer" also chooses one, but since it is so random the chances the computer wins is very limited. I then tried to do something like this in the AI() method and it seems to be on the right track but once one of the if's are satisfied the all the AI logic stops
         public void AI(){
              //horizontal AI defencive code
              if(buttons[1].getText().equals(buttons[2].getText()) && buttons[1].getText() != ""){
                   buttons[3].setText("O");
                   buttons[3].setEnabled(false);
              } else if(buttons[2].getText().equals(buttons[3].getText()) && buttons[2].getText() != ""){
                   buttons[1].setText("O");
                   buttons[1].setEnabled(false);
              } else if(buttons[4].getText().equals(buttons[5].getText()) && buttons[4].getText() != ""){
                   buttons[6].setText("O");
                   buttons[6].setEnabled(false);
              } else if(buttons[5].getText().equals(buttons[6].getText()) && buttons[5].getText() != ""){
                   buttons[4].setText("O");
                   buttons[4].setEnabled(false);
              } else if(buttons[7].getText().equals(buttons[8].getText()) && buttons[7].getText() != ""){
                   buttons[9].setText("O");
                   buttons[9].setEnabled(false);
              } else if(buttons[8].getText().equals(buttons[9].getText()) && buttons[8].getText() != ""){
                   buttons[7].setText("O");
                   buttons[7].setEnabled(false);
              } else {
                   Random x = new Random();
                   int y = 1 + x.nextInt(9);
                   if(buttons[y].getText() == "X" || buttons[y].getText() == "O" ){
                        AI();
                   } else {
                        buttons[y].setText("O");
                        buttons[y].setEnabled(false);
         }And basically what that does is it checks if I have two X's in a row horizontally, If I do it will place an O in the box preventing me from getting three in a row (only in horizontal rows). Of course I would iterate this over and over for all possible combinations of offensive moves and defensive moves and probably do it using a for loop but this is just some scratch code I threw together to show you my thoughts. And again my problem is once one of the conditions are satisfied it never checks the conditions again and I'm not sure why that is...
    So I'm looking for some ideas and/or some pseudo code to help me out a little.
    Thanks

    Well I did this and its a step closer to working but there is another bug and all this logic is hurting my head. Again lets say my grid is numbered like this
    1 | 2 | 3
    4 | 5 | 6
    7 | 8 | 9
    If I go 1, the computer will randomly pick a square thats not set. Lets say the computer picks 4. Now I pick 5 and the computer picks 9 because I would earn 3 in a row diagonally. Then I pick 2 and I can now win three in a row 2-5-8 or 1-2-3. The computer picks 3 because that logic is earlier in the code. BUT when I press 8 to to take the win, but the computer cheats and labels my button thats supposed to be an X as an O, so it should look like this:
    X | X | O
    O | X | 6
    7 | X | O
    but it does this
    X | X | O
    O | X | 6
    7 | O | O
    Here is the AI logic part (its mostly repetitive)

    partially.i am stuck at writing the code for "who is
    the winner"? and adding a button to start the new
    game ?please help me out to write the remaining?That question is almost impossible to answer because you didn't provide two vital pieces of information.
    1) What specific problems you're having.
    2) Relevant code.
    iam unable to attach the code now;So, you call the doctor on the phone, say, "I'm not feeling well. Please make me better. I can't come to your office or tell you anything about what's wrong with me now."
