游戏介绍：
“华容道”是一款比较古老的游戏，其源于三国时期著名的历史故事。华容道作为一个经典游戏，各部分的设计都恰到好处，非常巧妙，因此成为世界游戏界的三大不可思议。
“华容道”游戏初始时曹操被围在华容道最里层，玩家需要移动其他角色，使曹操顺利到达出口。玩家先选择需要移动的角色，然后拖动鼠标，被选中的角色就会向鼠标拖动的方向移动。最后，当成功地将曹操移动到出口时，游戏结束。
本次开发的“华容道”运行效果如下图所示：

游戏设计思路：
“华容道”整体可以看成5*4的网格，其中张飞、赵云、关羽、马超、黄忠各占两个格子，兵占一个格子，曹操最大占4个格子。在这里玩家鼠标的操作可以看成对带图标的JButton的拖动。声明变量W表示一个格子的边长，自定义数据结构Node类，用于保存每个关卡按钮的初始位置，使用继承自JButton的Person类用于每个带人物图标按钮的显示。
在这里我约定Node的x,y下标等同于图片按钮左上角对应的二维数组的x,y下标，id表示每个按钮的人物ID，direction为true时横放，direction为false时竖放。比如Node(0,0,0,true),表示曹操按钮位于左上角。
Node类：
package 华容道;
public class Node {
private int id;
private boolean direction;//true为横放，false为竖放
private int x;//左上角数组x下标
private int y;//左上角数组y下标
public Node(int id,int x,int y,boolean direction){
this.id = id;
this.x = x;
this.y = y;
this.direction = direction;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public boolean getDirection() {
return direction;
}
public void setDirection(boolean direction) {
this.direction = direction;
}
public int getX() {
return x;
}
public void setX(int x) {
this.x = x;
}
public int getY() {
return y;
}
public void setY(int y) {
this.y = y;
}
}
Person类是带人物ID的JButton
Person类：
package 华容道;
import java.awt.Color;
import java.awt.event.FocusEvent;
import java.awt.event.FocusListener;
import javax.swing.JButton;
public class Person extends JButton{
int id;//编号
String name;
public Person(int id,String str){
super("");
name = str;
this.id = id;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
}
MapFactory是存储游戏关卡数据的工厂类，MapFactory同时也支持历史记录的读写
MapFactory类：
package 华容道;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;

MapUtil是地图工具类，方法直接调用工厂类方法
MapUtil类：
package 华容道;
public class MapUtil {
public MapUtil(){
}
public Node[] getMap(int level){
return MapFactory.getMap(level);
}
//获取关卡历史记录
public int getRecord(int level){
return MapFactory.getRecord(level);
}
//更新指定关卡记录
public void updateRecode(int level,int record){
MapFactory.writeRecord(level, record);
}
}
GamePanel是继承自JPanel类的游戏面板类,内部包含游戏的主要逻辑：
①图片的获取
//获取图片
private void getIcons() {
for(int i=0;i<15;i++){
if(i==0){
pics[i] = Toolkit.getDefaultToolkit().getImage("D:/Game/KlotskiGame/pic"+i+".png").getScaledInstance(2*W, 2*W,Image.SCALE_SMOOTH);
}else if(i==1||i==2||i==3||i==4||i==5){
pics[i] = Toolkit.getDefaultToolkit().getImage("D:/Game/KlotskiGame/pic"+i+".png").getScaledInstance(2*W, W,Image.SCALE_SMOOTH);
}else if(i==6||i==7||i==8||i==9){
pics[i] = Toolkit.getDefaultToolkit().getImage("D:/Game/KlotskiGame/pic"+i+".png").getScaledInstance(W, W,Image.SCALE_SMOOTH);
}else{
pics[i] = Toolkit.getDefaultToolkit().getImage("D:/Game/KlotskiGame/pic"+i+".png").getScaledInstance(W,2*W,Image.SCALE_SMOOTH);
}
icons[i] = new ImageIcon(pics[i]);
}
repaint();
}②按钮图片显示和按钮位置的初始化
遍历地图按钮位置信息数组map,然后根据map数组元素对应的图标ID，对相应的人物图标按钮数组persons依次进行图标和位置的初始化。在这里只有黄忠、赵云、关羽、马超、张飞存在横放竖放的选择，竖放的图标ID = 横放的图标ID+9
//对游戏布局进行初始化
private void initialize() {
for(int i=0;i<10;i++){
switch(map[i].getId()){
case 0://曹操，占四格
persons[i] = new Person(0,"曹操");
persons[i].setIcon(icons[0]);
persons[i].setBounds(leftX+map[i].getY()*W, leftY+map[i].getX()*W, 2*W, 2*W);

}
break;
case 2://张飞，占两格
persons[i] = new Person(2,"张飞");
if(map[i].getDirection()){//横放
persons[i].setIcon(icons[2]);
persons[i].setBounds(leftX+map[i].getY()*W, leftY+map[i].getX()*W, 2*W, W);
}else{//竖放

}else{//竖放

if(map[i].getDirection()){//横放
persons[i].setIcon(icons[4]);
persons[i].setBounds(leftX+map[i].getY()*W, leftY+map[i].getX()*W, 2*W, W);
}else{//竖放
persons[i].setIcon(icons[13]);
persons[i].setBounds(leftX+map[i].getY()*W, leftY+map[i].getX()*W, W, 2*W);
}
break;
case 5://黄忠，占两格
persons[i] = new Person(5,"黄忠");
if(map[i].getDirection()){//横放
persons[i].setIcon(icons[5]);
persons[i].setBounds(leftX+map[i].getY()*W, leftY+map[i].getX()*W, 2*W, W);
}else{//竖放
persons[i].setIcon(icons[14]);
persons[i].setBounds(leftX+map[i].getY()*W, leftY+map[i].getX()*W, W, 2*W);
}
break;
case 6://小兵，占一格
persons[i] = new Person(6,"小兵");
persons[i].setIcon(icons[6]);
persons[i].setBounds(leftX+map[i].getY()*W, leftY+map[i].getX()*W, W, W);
break;
case 7://小兵，占一格
persons[i] = new Person(7,"小兵");
persons[i].setIcon(icons[7]);
persons[i].setBounds(leftX+map[i].getY()*W, leftY+map[i].getX()*W, W, W);
break;
case 8://小兵，占一格
persons[i] = new Person(8,"小兵");
persons[i].setIcon(icons[8]);

persons[i].setIcon(icons[9]);
persons[i].setBounds(leftX+map[i].getY()*W, leftY+map[i].getX()*W, W, W);
break;
}
persons[i].addMouseListener(this);
persons[i].addKeyListener(this);
this.add(persons[i]);
}
}③判断鼠标拖拽方向
记录下鼠标按下的像素点p1，再记录鼠标松开时的像素点p2，用p2去减去p1，得到x的位移量和y的位移量，如果x的位移量大于y的位移量，说明是水平方向拖拽，然后再判断p2.x-p1.x是正数还是负数，如果是正数，说明是水平向右拖拽，否则是水平向左拖拽。
private String getDirection(){
int dx,dy;
String direction;
dx = p2.x - p1.x;
dy = p2.y - p1.y;
if(dx==0&&dy==0){
return "no move";
}
if(Math.abs(dx)>Math.abs(dy)){//水平方向的偏移大于竖直方向的偏移，即水平方向运动
if(dx>0){//释放点在按压点右边
direction = "right";
}else{
direction = "left";
}
}else{//竖直方向的偏移大于水平方向的偏移，即竖直方向运动
if(dy>0){//释放点在按压点下边
direction = "down";
}else{
direction = "up";
}
}
return direction;
}
@Override
public void mousePressed(MouseEvent e) {
if(e.getSource()==null)//没有选中任何按钮，直接返回
return ;
p1.x = e.getX();
p1.y = e.getY();
}
@Override
public void mouseReleased(MouseEvent e) {
if(e.getSource()==null)
return ;
Person man = (Person) e.getSource();
p2.x = e.getX();
p2.y = e.getY();
String direction = getDirection();
boolean canMoveFlag;
if(direction.equals("up")){
canMoveFlag = getCanMoveFlag(man,UP);
if(canMoveFlag)
move(man,UP);
}else if(direction.equals("down")){
canMoveFlag = getCanMoveFlag(man,DOWN);
if(canMoveFlag)
move(man,DOWN);
}else if(direction.equals("left")){
canMoveFlag = getCanMoveFlag(man,LEFT);
if(canMoveFlag)
move(man,LEFT);
}else if(direction.equals("right")){
canMoveFlag = getCanMoveFlag(man,RIGHT);
if(canMoveFlag)
move(man,RIGHT);
}
}④判断是否可以向某个方向拖拽
getCanMoveFlag(Person man,int direction)根据传入的JButton对象和拖拽方向，获取是否可以移动的标记。
先获取传入的按钮对应的矩形对象，然后根据不同方向对该矩形移动一个单位格，然后对每个人物按钮对应的矩形对象判断是否相交，如果跟每个按钮对应的矩形都不相交，再跟边界的四个矩形进行是否相交的判断，最后返回canMoveFlag;
Rectangle leftBoundary = new Rectangle(leftX-10, leftY, 10, 5*W);
Rectangle rightBoundary = new Rectangle(leftX+4*W, leftY, 10, 5*W);
Rectangle upBoundary = new Rectangle(leftX, leftY-10, 4*W, 10);
Rectangle downBoundary = new Rectangle(leftX, leftY+5*W, 4*W, 10);
private boolean getCanMoveFlag(Person man, int direction) {
boolean canMoveFlag = true;
Rectangle manRect = man.getBounds();//返回点击的人物按钮对应的矩形对象
int x = manRect.x;
int y = manRect.y;
if(direction ==UP){
y -= W;
}else if(direction == DOWN){
y += W;
}else if(direction == LEFT){
x -= W;
}else if(direction == RIGHT){
x += W;
}
manRect.setLocation(x, y);//矩形进行了移动
for(int i=0;i<10;i++){
if(persons[i].getId()!=man.getId()){//位移后的矩形与其他人物图块对应的矩形进行碰撞检测
Rectangle personRect = persons[i].getBounds();
if(personRect.intersects(manRect)){//如果两矩形相交，说明不能移动
canMoveFlag = false;
}
}
}
//检测是否超出游戏区域
if(manRect.intersects(upBoundary)||manRect.intersects(downBoundary)||manRect.intersects(leftBoundary)||manRect.intersects(rightBoundary)){
canMoveFlag = false;
}
return canMoveFlag;
}⑤移动按钮并判断是否过关
如果可以向某个方向移动按钮，则改变根据方向改变按钮的位置，step++，然后判断曹操是否位于终点
private void move(Person man, int direction) {
switch(direction){
case UP:man.setLocation(man.getX(), man.getY()-W);break;
case DOWN:man.setLocation(man.getX(), man.getY()+W);break;
case LEFT:man.setLocation(man.getX()-W, man.getY());break;
case RIGHT:man.setLocation(man.getX()+W, man.getY());break;
}
step++;
GameClient.helpPanel.nowStep.setText(""+step);
if(isWin(man)){
if(level==10){JOptionPane.showMessageDialog(this, "恭喜通过最后一关");}
else{
String msg;
if(step<mapUtil.getRecord(level)){
msg = "恭喜你通过第"+level+"关！！！\n通关步数是"+step+"\n刷新了历史记录"+mapUtil.getRecord(level)+"步\n是否要进入下一关？";
mapUtil.updateRecode(level, step);
}else{
msg = "恭喜你通过第"+level+"关！！！\n通关步数是"+step+"\n"+"是否要进入下一关？";
}
int type = JOptionPane.YES_NO_OPTION;
String title = "过关";
int choice = 0;
choice = JOptionPane.showConfirmDialog(null, msg,title,type);
if(choice==1){
System.exit(0);
}else if(choice == 0){
level++;

}
}
private boolean isWin(Person man) {

return true;

HelpPanel类是继承自JPanel的辅助面板类，负责显示关卡名字和步数
HelpPanel类：
package 华容道;
import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class HelpPanel extends JPanel{
String[] names = new String[]{"七步成诗","横刀立马","屯兵东路","插翅难飞","巧过五关","层层设防","近在咫尺","兵临曹营","众志成城","佳人梳妆"};//十个关卡的名字
int level;
JPanel panelNorth = new JPanel(new GridLayout(4,2,10,30));
static JLabel nowStep = new JLabel("0");
JLabel nowName = new JLabel("");
JLabel record = new JLabel("9999");
static JButton restart = new JButton("重置");
public HelpPanel(int level){
this.level = level;
this.setVisible(true);
this.setLayout(new BorderLayout());//当前面板
panelNorth.add(new JLabel("关卡名字："));
panelNorth.add(nowName);
panelNorth.add(new JLabel("当前步数："));
panelNorth.add(nowStep);
panelNorth.add(new JLabel("历史记录："));
panelNorth.add(record);//历史记录
panelNorth.add(restart);
this.add(panelNorth,BorderLayout.NORTH);
initialize();
}
public void setLevel(int level){
this.level = level;
initialize();
}
private void initialize() {
// System.out.println("level is "+level);
// System.out.println(names[level-1]);
nowName.setText(names[level-1]+"");
nowStep.setText("0");
record.setText(""+MapFactory.getRecord(level));
}
}
游戏窗口类GameClient类用于装载游戏面板和辅助面板。
GameClient类：
package 华容道;
import java.awt.BorderLayout;
import java.awt.Container;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class GameClient extends JFrame{
static GamePanel gamePanel;
static HelpPanel helpPanel;
static Container panel;//窗口容器
public GameClient(){
helpPanel = new HelpPanel(1);
gamePanel = new GamePanel(1);//设置关卡
gamePanel.setLayout(new BorderLayout());
panel = this.getContentPane();
panel.setLayout(new BorderLayout());
panel.add(helpPanel,BorderLayout.EAST);
panel.add(gamePanel,BorderLayout.CENTER);
this.setSize(650,650);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setTitle("华容道");
this.setVisible(true);
this.setResizable(false);
}
public static void main(String[] args) {
new GameClient();
}
}
这次游戏开发中途遇到了一些显示问题的bug（第二关开始最后一个人物按钮变成全屏），导致出现了很多复杂的静态变量引用，不过目前已经解决，实现略繁琐，就不细说了。
ps:根据关卡名字均可以在百度上找到解密过程，(#^.^#)
