Well, we've been working on a Checkers program in Computer Science 3 for around 3 days now. This is an unfinished, and probably badly coded program, but it works for the most part. It does have it's share of bugs, though. First of all, if you click a piece that can't move anywhere, you're stuck. You have to restart the game. Also, the pieces are able to move in an L-shape at time, which I will fix. Also the king can move 2 squares, so I'll need to fix that, and occasionally the left-most colum crashes the code for some reason. Also, I haven't added code to check for a win yet. I'll do all this later. I'll fix these bugs, but at a later time. I will also attach all the images for the board and the pieces at a later time. This is what I have so far:
Board.java: import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.io.*;
public class Board extends JPanel
{
public Piece board[][] = new Piece[8][8];
private Image boardImage = Toolkit.getDefaultToolkit().getImage("Board.JPG");
private Image greyPieceImage = Toolkit.getDefaultToolkit().getImage("greyPiece.JPG");
private Image redPieceImage = Toolkit.getDefaultToolkit().getImage("redPiece.JPG");
private Image redKingImage = Toolkit.getDefaultToolkit().getImage("redKing.jpg");
private Image greyKingImage = Toolkit.getDefaultToolkit().getImage("greyKing.jpg");
public Board(){
for(int x = 0; x < board.length; x++)
for(int y = 0; y < board[x].length; y++)
board[x][y]= new Piece(0, false);
setBoard();
repaint();
show();
}
public void setBoard(){
for(int c = 0; c <= 2; c++){
if(c == 1){
for(int r = 0; r <= 6; r+=2){
board[c][r].setPlayer(1);
}
}
if(c == 0 || c==2){
for(int r = 1; r <= 7; r+=2){
board[c][r].setPlayer(1);
}
}
}
//----------------------------------------------\\
for(int c = 7; c >= 5; c--){
if(c == 7 || c == 5){
for(int r = 0; r <= 6; r+=2){
board[c][r].setPlayer(2);
}
}
if(c == 6){
for(int r = 1; r <= 7; r+=2){
board[c][r].setPlayer(2);
}
}
}
for(int x = 0; x < board.length; x++){
for(int y = 0; y < board[x].length; y++){
System.out.print(board[x][y].getPlayer() + " ");
}
System.out.println();
}
}
public void paint(Graphics window){
window.drawImage(boardImage, 0, 0, 320, 320, this);
for(int i = 0; i<8; i++)
{
for(int j = 0; j<8; j++)
{
if(board[i][j].getPlayer()==1)
{
window.drawImage(redPieceImage, 40*j, 40*i, 39, 39, this);
// System.out.println("1");
}
if(board[i][j].getPlayer()==2)
{
window.drawImage(greyPieceImage, 40*j, 40*i, 39, 39, this);
// System.out.println("2");
}
if(board[i][j].getPlayer()==3)
{
window.drawImage(redKingImage, 40*j, 40*i, 39, 39, this);
}
if(board[i][j].getPlayer()==4)
{
window.drawImage(greyKingImage, 40*j, 40*i, 39, 39, this);
}
}
}
}

looks cool. i will have to compile this on my box this weekend... perhaps I can help you get the things you mentioned working if time permits.

Just a bit of advice, it wont affect performance i dont think, but in piece, a new piece will never be a king? if that is true you dont need to set king variable on load of the piece. Just set it to false in global variable.

Good point. Actually, I'm not using my king variable at all, as I originally planned to. I need to go through and clean up the code a little before I actually turn it in. Thanks for the advice.

I would try to help with the few bugs you have but i am not a graphics programmer, i am either web or command line running programs at the minute, need to span out a bit just dont have the time.
And you must use your king variable at some point? otherwise, its not really object orientated, as the piece is either a king or not a king, so just calling your getKing method would save a lot of computations to work that out.
