Need a little help implementing mouse in checkers game.

[stinger4life]

Hey guys,

Things have been going strong on my checkers game, I have got most of the graphical elements down, I just need a little help on how to get the mouse to move each checker. Here is my code:

import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.awt.Color.*;
import java.io.*;
import javax.imageio.*;
import javax.swing.*;
import java.awt.Font;

public class LoadImageApp extends Component
{
//Create image location in memory for checkerboard.
BufferedImage board;

//Create image location in memory for red checkers.
BufferedImage redchecker1;
BufferedImage redchecker2;
BufferedImage redchecker3;
BufferedImage redchecker4;
BufferedImage redchecker5;
BufferedImage redchecker6;
BufferedImage redchecker7;
BufferedImage redchecker8;
BufferedImage redchecker9;
BufferedImage redchecker10;
BufferedImage redchecker11;
BufferedImage redchecker12;

//Create image location in memory for black checkers.
BufferedImage blackchecker1;
BufferedImage blackchecker2;
BufferedImage blackchecker3;
BufferedImage blackchecker4;
BufferedImage blackchecker5;
BufferedImage blackchecker6;
BufferedImage blackchecker7;
BufferedImage blackchecker8;
BufferedImage blackchecker9;
BufferedImage blackchecker10;
BufferedImage blackchecker11;
BufferedImage blackchecker12;

//Windows asking for player 1 and player 2 names.
String userInput1 = JOptionPane.showInputDialog("Enter 1st Player's Name (Black):");
String userInput2 = JOptionPane.showInputDialog("Enter 2nd Player's Name (Red):");




public void paint(Graphics g)
{
//Font Array
String[] strFontList = Toolkit.getDefaultToolkit().getFontList();

//Placement of checkerboard.
g.drawImage(board, 0, 0, null);

//Placement of red checkers.
g.drawImage(redchecker1, 103, 25, null);
g.drawImage(redchecker2, 260, 25, null);
g.drawImage(redchecker3, 420, 25, null);
g.drawImage(redchecker4, 576, 25, null);
g.drawImage(redchecker5, 25, 105, null);
g.drawImage(redchecker6, 182, 105, null);
g.drawImage(redchecker7, 340, 105, null);
g.drawImage(redchecker8, 498, 105, null);
g.drawImage(redchecker9, 103, 185, null);
g.drawImage(redchecker10, 260, 185, null);
g.drawImage(redchecker11, 420, 185, null);
g.drawImage(redchecker12, 576, 185, null);

//Placement of black checkers.
g.drawImage(blackchecker1, 25, 576, null);
g.drawImage(blackchecker2, 180, 576, null);
g.drawImage(blackchecker3, 340, 576, null);
g.drawImage(blackchecker4, 500, 576, null);
g.drawImage(blackchecker5, 100, 496, null);
g.drawImage(blackchecker6, 260, 496, null);
g.drawImage(blackchecker7, 420, 496, null);
g.drawImage(blackchecker8, 575, 496, null);
g.drawImage(blackchecker9,25, 418, null);
g.drawImage(blackchecker10, 180, 418, null);
g.drawImage(blackchecker11, 339, 418, null);
g.drawImage(blackchecker12, 497, 418, null);

//Font for sidebar.
g.setColor(Color.black);
Font gf = new Font(strFontList[1], Font.BOLD, 15);
g.setFont(gf);
g.drawString("Black: " + userInput1, 700 ,500);
g.setColor(Color.red);
g.drawString("Red: " + userInput2, 700 ,100);
}

public LoadImageApp()
{
try
{
//Inputs checkerboard image into the checkerboard memory slot.
board = ImageIO.read(new File("checkerboard.gif"));

//Inputs red checker image into the red checker memory slots.
redchecker1 = ImageIO.read(new File("redchecker.png"));
redchecker2 = ImageIO.read(new File("redchecker.png"));
redchecker3 = ImageIO.read(new File("redchecker.png"));
redchecker4 = ImageIO.read(new File("redchecker.png"));
redchecker5 = ImageIO.read(new File("redchecker.png"));
redchecker6 = ImageIO.read(new File("redchecker.png"));
redchecker7 = ImageIO.read(new File("redchecker.png"));
redchecker8 = ImageIO.read(new File("redchecker.png"));
redchecker9 = ImageIO.read(new File("redchecker.png"));
redchecker10 = ImageIO.read(new File("redchecker.png"));
redchecker11 = ImageIO.read(new File("redchecker.png"));
redchecker12 = ImageIO.read(new File("redchecker.png"));

//Inputs black checker image into the black checker memory slots.
blackchecker1 = ImageIO.read(new File("blackchecker.png"));
blackchecker2 = ImageIO.read(new File("blackchecker.png"));
blackchecker3 = ImageIO.read(new File("blackchecker.png"));
blackchecker4 = ImageIO.read(new File("blackchecker.png"));
blackchecker5 = ImageIO.read(new File("blackchecker.png"));
blackchecker6 = ImageIO.read(new File("blackchecker.png"));
blackchecker7 = ImageIO.read(new File("blackchecker.png"));
blackchecker8 = ImageIO.read(new File("blackchecker.png"));
blackchecker9 = ImageIO.read(new File("blackchecker.png"));
blackchecker10 = ImageIO.read(new File("blackchecker.png"));
blackchecker11 = ImageIO.read(new File("blackchecker.png"));
blackchecker12 = ImageIO.read(new File("blackchecker.png"));
}
catch (IOException e)
{
}

}

public static void main(String[] args)
{
//Creates game window, window name, and adjusts size accordingly.
JFrame f = new JFrame("Dan's, Fil's, And Gianni's Checkers V1.0");

f.addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent e)
{
System.exit(0);
}
});

f.add(new LoadImageApp());
f.pack();
f.setVisible(true);
f.setSize(1015, 705);



}
}

Also attached are the 5 pictures currently needed to run it.

code:

BufferedImage redchecker1; BufferedImage redchecker2; BufferedImage redchecker3; BufferedImage redchecker4; BufferedImage redchecker5; BufferedImage redchecker6; BufferedImage redchecker7; BufferedImage redchecker8; BufferedImage redchecker9; BufferedImage redchecker10; BufferedImage redchecker11; BufferedImage redchecker12;

Seriously dude... arrays.

Yea I know I'm getting there, but any help with the actual question asked?

MouseListener interface.

[Dannyd534]

Maybe we should explain to him how to use the MouseListner interface code to help him out

[McKenzie]

http://java.sun.com/docs/books/tutorial/uiswing/events/mouselistener.html

Sun's site is usually the best place to go for answers. Basically you do three things to add the mouse.
1. Say that your program is implementing the MouseListener interface.

Java:

public class LoadImageApp extends Component implements MouseListener

2. Add a MouseListener in your constructor so that Windows tells you when Mouse events happen.

Java:

addMouseListener (this);

3. Add the 4 event handlers that the MouseListener is looking for:

Java:

public void mousePressed(MouseEvent e) {         System.out.println(e);     }     public void mouseEntered(MouseEvent e) {}     public void mouseExited(MouseEvent e) {}     public void mouseClicked(MouseEvent e) {}        public void mouseReleased(MouseEvent e) {}

And you may want to do more than just println the event.

Interfaces are a vital concept for a Java programmer to learn. If he learns how they work, and knows how to use the online Java documentation, we will not need to explain MouseListener at all.

and great explination McKenzie

ontop of not using arrays, it is quite pointless to load the same image over and over again to a new variable,
he might be encouraged to use one image for red, (or two if have image for kings) and one image for black (two if have image for kings).
