I have problem with the Play Again button, which is to reset the panel to initial state.
The Play Again button should reset the panel, it does reshuffle the gameList, but not reset the panel, which means all the buttons remain and lost the ActionListener function.
Here is my program :
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import static java.util.Collections.*;
public class MemoryGame extends JFrame
{
private JButton exitButton, replayButton;
private JButton[] gameButton = new JButton[16];
private ArrayList<Integer> gameList = new ArrayList<Integer>();
private int counter = 0;
private int[] buttonID = new int[2];
private int[] buttonValue = new int[2];
public static Point getCenterPosition(int frameWidth, int frameHeight)
{
Toolkit toolkit = Toolkit.getDefaultToolkit();
Dimension dimension = toolkit.getScreenSize();
int x = (dimension.width - frameWidth)/2;
int y = (dimension.height - frameHeight)/2;
return (new Point(x,y));
}
public MemoryGame(String title)
{
super(title);
initial();
}
public void initial()
{
for (int i = 0; i < gameButton.length; i++)
{
gameButton[i] = new JButton();
gameButton[i].setFont(new Font("Serif", Font.BOLD, 28));
gameButton[i].addActionListener(new ButtonListener());
}
exitButton = new JButton("Exit");
replayButton = new JButton("Play Again");
exitButton.addActionListener(new ButtonListener());
replayButton.addActionListener(new ButtonListener());
Panel gamePanel = new Panel();
gamePanel.setLayout(new GridLayout(4, 4));
for (int i = 0; i < gameButton.length; i++)
{
gamePanel.add(gameButton[i]);
}
Panel buttonPanel = new Panel();
buttonPanel.add(replayButton);
buttonPanel.add(exitButton);
buttonPanel.setLayout(new GridLayout(1, 0));
add(gamePanel, BorderLayout.CENTER);
add(buttonPanel, BorderLayout.SOUTH);
for (int i = 0; i < 2; i++)
{
for (int j = 1; j < (gameButton.length / 2) + 1; j++)
{
gameList.add(j);
}
}
shuffle(gameList);
int newLine = 0;
for (int a = 0; a < gameList.size(); a++)
{
newLine++;
System.out.print(" " + gameList.get(a));
if (newLine == 4)
{
System.out.println();
newLine = 0;
}
}
}
public boolean sameValues()
{
if (buttonValue[0] == buttonValue[1])
{
return true;
}
return false;
}
private class ButtonListener implements ActionListener
{
public void actionPerformed(ActionEvent e)
{
if (exitButton == e.getSource())
{
System.exit(0);
}
else if (replayButton == e.getSource())
{
initial();
}
for (int i = 0; i < gameButton.length; i++)
{
if (gameButton[i] == e.getSource())
{
gameButton[i].setText("" + gameList.get(i));
gameButton[i].setEnabled(false);
counter++;
if (counter == 3)
{
if (sameValues())
{
gameButton[buttonID[0]].setEnabled(false);
gameButton[buttonID[1]].setEnabled(false);
}
else
{
gameButton[buttonID[0]].setEnabled(true);
gameButton[buttonID[0]].setText("");
gameButton[buttonID[1]].setEnabled(true);
gameButton[buttonID[1]].setText("");
}
counter = 1;
}
if (counter == 1)
{
buttonID[0] = i;
buttonValue[0] = gameList.get(i);
}
if (counter == 2)
{
buttonID[1] = i;
buttonValue[1] = gameList.get(i);
}
}
}
}
}
public static void main(String[] args)
{
int x, y;
int width = 500;
int height = 500;
Point position = getCenterPosition(width, height);
x = position.x;
y = position.y;
JFrame frame = new MemoryGame("Memory Game");
frame.setBounds(x, y, width, height);
frame.setVisible(true);
frame.setResizable(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
How can I solve this problem?
EDIT :
Another problem is after reset(), all buttons seem like become sameValue(). I have insert some audio to the buttons, and it’s happen in the condition of the ButtonListener. Here is the part :
if (counter == 3)
{
if (sameValues())
{
gameButton[buttonID[0]].setEnabled(false);
gameButton[buttonID[1]].setEnabled(false);
}
Seems like it’s satisfy the condition sameValue(), but why?
LATEST UPDATE :
Problem Solved. Latest code is not uploaded.
Ok, I’ve fixed your code.
Be sure to check out my comment to your question and let me know if it works (I did a quick test and it went fine)
