3d project cube shaped tic tac toe
with java3d could i build the following?
I'm looking to make a 3d 4X4X4 cube for playing a game of tic tac toe.
i want the 3d cube to have hot spots on it, where a click of the mouse would assign an x or o in that location.
is this possible?
Sorta like:

This is an example that comes with the java 3d libraries.

}right now as you can see i just have the actionPerformed to print the number in the console window cuz i wanted to make sure it works. What do i need to put in the actionPerformed to get an X or an O to print on the button?its not working, what am i missing?
String text="X";
if(event.getActionCommand().equals("0"))
buttons[][].setText(text);its underlined. -

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.

I need help on a Tic Tac Toe game I am making for a class. I had finished a "2 Player" version and my instructor wants me to simulate a computer "AI" now. I cannot figure out what I'm doing wrong. The order of precedence is this:
1. X moves first (the player)
2. Computer moves to win.
3. If it can't win, it moves to block a win
4. If it can't block a win, it moves to the best possible spot to set up a win.
I think my problems are with several methods, but I cannot figure out what I'm doing wrong. Every time I look at my code, it just makes "sense". I think my problems could probably be found in 4 methods, setButtonText(), findOpen(), findBestOpen() and tempCheck(). I would like hints or maybe if I could get a second look at it for me.

I click to make "X"'s (the player's move). X appears but O never does, although a button is highlighted. If I keep pressing the buttons, all X's appear until the last move, when an "O" appears.I don't know if it's the problem, but
checkWinner("0");looks suspicious. (2nd invocation in your tempCheck() method).
Your program seems awfully brittle. How would you do it if you had a 4 x 4 board? Or 5 x 5?
Also, your 'winningCombos' array is repeated everywhere it's used. There's no need for that; just make it an instance variable/constant.

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:

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!!

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; -
A Tic Tac Toe board is represented as an array of 9 chars. Write a program that will allow two users to play tic tac toe. The player should ask for moves alternately from players X and O. The program is too dumb to check whether anyone has won or lost and just stops after 9 turns. The program should display the game position as follows after each move.
The output should be somewhat as follows:
Choose a spot (1 to 9) for X: 1
X || ||
|| ||
|| ||

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?

hi, I've created my code and for the tic tac toe grid but I dont know how to make it look like a grid (i.e
1 2 3
4 5 6
7 8 9)
it has came out as "123X56789" "X" meaning a number has taken up a cross.
can anyone help??
heres the code of the grid........
// GAMEINTERFACE
public class GameInterface extends MyPrint
private String theGrid;
final static char NOUGHT='O', CROSS='X';
public GameInterface()
theGrid = "?123456789";
public void pictureBoard(String theGrid)
for(int i = 1; i<theGrid.length(); i++)
int hit = i%3;
if(hit!=0)
myPrint(Character.toString((theGrid.charAt(i))));
else
myPrint(Character.toString((theGrid.charAt(i))));
public void play(char cell, boolean playTurn)
char noughtCross = ' ';
if(playTurn = true)
noughtCross = CROSS;
else if(playTurn = false)
noughtCross = NOUGHT;
if('1'<=cell || cell<='9')
theGrid=theGrid.substring(0,theGrid.indexOf(cell)) + Character.toString(CROSS) + theGrid.substring(theGrid.indexOf(cell)+1);
else if('1'<=cell || cell<='9')
theGrid=theGrid.substring(0,theGrid.indexOf(cell)) + Character.toString(NOUGHT) + theGrid.substring(theGrid.indexOf(cell)+1);
public String display()
return theGrid;
Plus how do i create a 'O' in the output as 'X' appears for the 2 players playing.
this will be very appreciated.
many thanks
Davejust tried that warnerja, it doesnt work either.
it has to be linked to this other class(program below)
//GAME
public class Game extends MyPrint
GameInterface gameInterface;
String s = "?123456789";
Player player1;
Player player2;
public Game() // Constructor
public void makeMove()
gameInterface = new GameInterface ();
player1 = new Player ();
player2 = new Player ();
myPrintln("Enter name of player");
String FP = c.input.readString();
myPrintln(FP, SYSTEM);
myPrintln("Enter name of other player");
String SP = c.input.readString();
myPrintln(SP, SYSTEM);
gameInterface.pictureBoard(s);
myPrintln("");
//boolean whoWon=false;
int loop = 0;
while(loop<=6)
player1.setName(FP);
myPrintln(player1.getName() + " (X) to play");
myPrintln("Enter move by selecting number from grid");
myPrintln("or 0 to draw");
char name1 = c.input.readChar();
name1 = c.input.readChar();
boolean playTurn = true;
gameInterface.play(name1, true);
gameInterface.pictureBoard(gameInterface.display());
myPrintln("");
//if(checkWin(gameInt.display()))
// whoWon=true;
// break;
player2.setName(SP);
myPrintln(player2.getName() + " (O) to play");

char name2 = c.input.readChar();
name2 = c.input.readChar();
playTurn = false;

Hi,
i am trying to create the tris game in java (maybe you know this game as tic tac toe). I created windows and the alghoritm to play. But now i have the problem to create the board. My idea is to create a board with nine clickable cells, the player clicks on the cell he wants (if it's free), then the computer plays and so on...but i don't have the knowledges of making complex graphic things in java. How can I do?ok, and how can i manage the player's click?MouseListener on the JLabel.
remember
also that when the player clicks, the program must
draw a symbol (x or o depending from the choice of
player). how can i do all this things? For a noob
like me this is very difficultRead the tutorials. I'm not going to explain to you how to create your app if you can read it up yourself. -
Why do I keep getting the following errors in a very simple, basic TIC TAC TOE program? Any help would be greatly appreciated. Thanks.

System.out.println();the "else without if" means that you have an else statement that wasn't attached to an if statement. In your case, it seems to be because you had multiple statements following an if statement, and you didn't enclose them in a single block.
The "cannot resolve symbol" means that you referred to something that wasn't defined. Either it's your code, and you forgot to define it, or you were referring to someone else's code, in which case you probably forgot an import statement, or you're using their code incorrectly. -
Test out this Tic Tac Toe game please
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. So can you guys download the stuff and play it a few times. Give me any suggestions or bug reports. This is v. 1.0 and there isn't a winner decider yet. Thanks and hope you have fun!
You will need to download JUDO

heres my code: my question is at the bottom

System.out.println("9: Bottom Right Corner");
System.out.print("Choose where you want to put your mark by picking its number:");

one.board(); //draws a tic tac toe board
one.circle(-120, 65); //draws a circle at that location
else if(choice == 2);
one.board();
one.circle(-50, 65);
now my question, if i input 1 it draws the circle but it then continues on and draws the second circle to without me telling it to. but if i skip right to drawing the second circle it does and ignores the first one. thanks in advance for any inputif(choice == 1)
one.board(); //draws a tic tac
one.circle(-120, 65); //draws a
else if(choice == 2);
one.board();
one.circle(-50, 65);
} Take the semicolen off of the second condition. It should be " if ( choice == 2 ) { ". Otherwise, the compiler thinks there is nothing to be executed as the result of choice == 2, and the instructions to draw the second circle are a seperate block of code that gets executed regardless of whether the choice is one, two, or fifteen billion.
