As the topic says, I created a chess game as my first 2D game, but when I try to create an executable jar file from it, I get strange behavior, and when I move the pieces, the game becomes chaotic and nothing works. The strange thing is that inside the eclipse, everything works fine. When it creates the executable file of the jar file, eclipse gives the following error:
Resource is out of sync with the file system: '/Chess_Project/src/.DS_Store'.
I don’t remember that even such a file was in my project, so I think it is a hidden file or a system file. Then I tried to export it as a regular Jar file with eclipse and after it through the terminal (by the way, I am a Mac OSX lion user), but I failed in both directions and got NullPointerExceptiona few more errors. I got a little familiar with the manifest files and tried to compile my code myself, and then export each of the methods that I mentioned above.
I tried to solve it for a week or so and asked for help in various forums, but no luck.
Thanks to the Francis, I realized that the problem could arise from my code. And also my question: "why am I getting weird behavior in the runnable jar file (which means that everything is not working as it should), when I run it inside eclipse, everything works fine?" , here is the main class of my code:
import java.awt.*;
import javax.swing.SwingUtilities;
import javax.swing.*;
public class MainWindowChess {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
JFrame f = new JFrame("Chess");
SwingUtilities.isEventDispatchThread();
f.setLayout(new BorderLayout());
f.setSize(40 * 8, 40 * 9 - 20);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setResizable(false);
Board b = new Board();
f.add(b);
f.setVisible(true);
System.out.println("check");
}
});
}
}
By the way, it is amazing that people respond so quickly, I am glad to see so many people who want to help others.
