Need help with program?

[Ryden7]

Hi everyone, im new to the forums.

I was looking for some help on my program. Im supposed to be designing a game that's called "Lights Out." Here is an example of the game: Sarksap | Lights Out Game

So far I have been stuck on creating the buttons and how the game will work. I have a good idea of what to do because ive been thinking about it for a couple of days. For this program im using a 2d array to create it but the hard part for me is implementing it into the board. Here is my code:

import javax.swing.*;

import java.awt.; import java.awt.event.;

public class Game extends JFrame implements ActionListener {

public static void main (String[] args) {

    Game c = new Game();
    c.setVisible(true);
}

private JButton rows;
private JButton columns;



public Game () {

    //Everything goes on the main panel
    JPanel mainPanel = new JPanel();

    // When the window is closed, the application ends
            setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

            // Set title and size
            setTitle("Lights Off");
            setSize(400, 400);



            // This only/merely allocates an array of JButtons.
            // Each element of the array is null.
            JButton[][] boxes = new JButton[5][5];
            for(int r = 0; r < boxes.length; r++) {
                for(int c = 0; c < boxes[r].length; c++) {
                    int n = r*boxes[r].length + c+1;


                    JButton[][] calculate = new JButton[i][x];
                    //mainPanel.add(calculate);

                }
            }









}


@Override
public void actionPerformed(ActionEvent e) {
    // TODO Auto-generated method stub

}

}

    /*

    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setTitle("Lights OFF");
    JPanel mainPanel = new JPanel(new GridLayout(5,5));;
    mainPanel.setLayout(new BorderLayout());

    setSize(300, 300);

             JButton[][] button = new JButton[0][0];

             for(int r = 0; r < button.length; r++) {
                      for(int c = 0; c < button[r].length; c++) {
                        mainPanel.add(button[r][c]);
                      }
                    } 
        */

I commented some stuff out that I thought would not work or I was still working with it when I found a better solution. To change horizontal and vertical colors, I decided to use the [r+1][c+1] etc to change the positions of the ones above, below, right, and left of the button clicked. I just don't know how to implement it. Any help is appreciated.

Thanks!

You'd be better off implementing your game logic separately from the GUI (as in, using separate classes). Focus on the former before trying to build the latter.

Thanks for the reply. The way its supposed to be setup is all under 1 class. This is my first semester in Java and I find it to be kind of difficult. I just came across a way to create 25 buttons. But now I need to access them. I was thinking of making the logic of how the buttons work in a different method

The way this is going to work is, when a button is clicked, its going to find that button, find out the position, subtract 1 from the x and , then add 1 to x and y to find out all of the positions around the one that was clicked then change the colors of those ones. The problem right now is adding the action listener which im trying to do right now. Like I said, I am very new to programming and I am trying my best.

        JButton[][] grid; //names the grid of buttons
 
        public ButtonGrid(int width, int length){ //constructor
                frame.setLayout(new GridLayout(width,length)); //set layout
                grid=new JButton[width][length]; //allocate the size of grid
                for(int y=0; y<length; y++){
                        for(int x=0; x<width; x++){
                                grid[x][y]=new JButton("("+x+","+y+")"); //creates new button    
                                frame.add(grid[x][y]); //adds button to grid
                        }
                }
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.pack(); //sets appropriate size for frame
                frame.setVisible(true); //makes frame visible
                
                
                
                
        }
        public static void main(String[] args) {
                new ButtonGrid(5,5);//makes new ButtonGrid with 2 parameters
        }
