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.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);
}
}
}
}
}
