[JAVA] Tic Tac Toe - Solixious - 02-17-2013

I just made this because I was feeling bored today. It behaves strangely once in a while whose reason I'm still trying to figure out. Other than that, it works alright I guess. You have to play Tic Tac Toe against AI. It is not difficult to win, but don't take this AI lightly Biggrin

RE: [JAVA] Tic Tac Toe - Deque - 02-18-2013

It is really fun to play it, tried and most of the time I get a tie.
Your code looks a bit messy, though. Try to seperate gui and game logic into different classes (Separation of Concerns).

If you are interested, I might publish some papers about design patterns and code smells (I've already written some).

Try if that helps:

Code:
public static void main(String args[]) throws Exception {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                TicTacToe ttt = new TicTacToe();
                byte b[][] = { { 0, 0, 0 }, { 0, 0, 0 }, { 0, 0, 0 } };
                ttt.b = b;
            }
        });
}

Even if it doesn't help for your specific problem, you should start every Swing GUI this way. Otherwise you might get problems.
Look here for explanation: http://docs.oracle.com/javase/tutorial/uiswing/concurrency/initial.html

RE: [JAVA] Tic Tac Toe - Psycho_Coder - 02-18-2013

if you can then please post somethings regarding design patterns as you just told, it is always good to learn something new.:angel:

Thank you for feedback Deque. I guess it is right, my codes usually look like a mess and I need to improve on that. I could use some suggestions.
I'll try the solution you provided for the swing.

RE: [JAVA] Tic Tac Toe - Psycho_Coder - 05-19-2013

Code:
public void mouseClicked(MouseEvent e)
    {
    }
    public void mouseEntered(MouseEvent e)
    {
    }
    public void mouseExited(MouseEvent e)
    {
    }

If you extend your class with MouseAdapter then you don't need to write these extra empty methods.

RE: [JAVA] Tic Tac Toe - ArkPhaze - 05-20-2013

What are the empty void's for? lol. And your checkVictory() function is the cheap way of doing it. Wink This code could be shortened a lot. I don't know much about the graphics because i'm not a Java dev. I might be getting into Android programming soon however. But for the logic, I came up with some good algorithms, that would work for any sized board if needed, and any number of needed player markers in a line.

(05-20-2013, 10:46 PM)ArkPhaze Wrote: What are the empty void's for? lol.

He extends the MouseListener interface, so he has to implement all methods of that interface no matter if he needs them or not.
Feurex gave the right suggestion here, which is implementing the MouseAdapter instead. But actually the MouseAdapter is also just a class with empty method implementations.

Have you ever heard that Java is verbose? It definitely is. My reason to switch to Scala--it looks like the child of Java and Haskell.

RE: [JAVA] Tic Tac Toe - ArkPhaze - 05-21-2013

Ahh, I wasn't looking at the implementation... I honestly haven't heard or read much about Java lol. It just didn't really interest me before. I could grasp it though if I wanted with some time as it's similar to C#. Some very minor things that I don't like though; C# habits that would make Java programming a real b*tch.

Code:
implements MouseListener

I'm also used to coding standards where that MouseListener should really be IMouseListener if that is an interface... Confusedurprised:

Perhaps that's why I overlooked it...

You are right, putting the 'I' in front of interfaces is not a standard in Java.
Nor can you use any override or virtual modifier. Every method is virtual unless you declare it as final (=sealed in C#).
C# did it right to make methods final per default.

RE: [JAVA] Tic Tac Toe - ArkPhaze - 05-21-2013

Good to know before that ends up screwing me up once I get into Android development..
