Java棋類游戲實踐之單機版五子棋

本文實例講述了java實現的五子棋遊戲代碼，分享給大家供大家參考，具體代碼如下

一、實踐目標

1.掌握JavaGUI界面設計
2.掌握鼠標事件的監聽（MouseListener，MouseMotionListener）

二、實踐內容

設計一個簡單的五子棋程序，能夠實現五子棋下棋過程。如下圖所示

2.棋子類

package cn.edu.ouc.fiveChess; import java.awt.Color; /** * 棋子類*/ public class Point { private int x;//棋盤中的x索引private int y;//棋盤中的y索引private Color color;//顏色public static final int DIAMETER=30;//直徑public Point(int x,int y,Color color){ this.x=x; this.y=y; this.color=color; } public int getX(){//拿到棋盤中x的索引return x; } public int getY(){ return y; } public Color getColor(){//獲得棋子的顏色return color; } }

3.五子棋主框架類

package cn.edu.ouc.fiveChess; import java.awt.event.*; import java.awt.*; import javax.swing.*; /* 五子棋主框架，程序*/ public class StartChessJFrame extends JFrame { private ChessBoard chessBoard; private JPanel toolbar; private JButton startButton,backButton,exitButton; private JMenuBar menuBar; private JMenu sysMenu; private JMenuItem startMenuItem,exitMenuItem,backMenuItem; //重新開始，退出，和悔棋菜單項public StartChessJFrame(){ setTitle("單機版五子棋");//設置標題chessBoard=new ChessBoard(); Container contentPane=getContentPane(); contentPane.add(chessBoard); chessBoard.setOpaque(true); //創建和添加菜單menuBar =new JMenuBar();//初始化菜單欄sysMenu=new JMenu("系統");//初始化菜單//初始化菜單項startMenuItem=new JMenuItem("重新開始"); exitMenuItem =new JMenuItem("退出"); backMenuItem =new JMenuItem("悔棋"); //將三個菜單項添加到菜單上sysMenu.add(startMenuItem); sysMenu.add(exitMenuItem); sysMenu.add(backMenuItem); //初始化按鈕事件監聽器內部類MyItemListener lis=new MyItemListener(); //將三個菜單註冊到事件監聽器上this.startMenuItem.addActionListener(lis); backMenuItem.addActionListener(lis); exitMenuItem.addActionListener(lis); menuBar.add(sysMenu);//將系統菜單添加到菜單欄上setJMenuBar(menuBar);//將menuBar設置為菜單欄toolbar=new JPanel();//工具面板實例化//三個按鈕初始化startButton=new JButton("重新開始"); exitButton=new JButton("退出"); backButton=new JButton("悔棋"); //將工具面板按鈕用FlowLayout佈局toolbar.setLayout(new FlowLayout(FlowLayout.LEFT)); //將三個按鈕添加到工具面板toolbar.add(startButton); toolbar.add(exitButton); toolbar.add(backButton); //將三個按鈕註冊監聽事件startButton.addActionListener(lis); exitButton.addActionListener(lis); backButton.addActionListener(lis); //將工具面板佈局到界面”南方“也就是下方add(toolbar,BorderLayout.SOUTH); add(chessBoard);//將面闆對象添加到窗體上//設置界面關閉事件setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //setSize(800,800); pack();//自適應大小} private class MyItemListener implements ActionListener{ public void actionPerformed(ActionEvent e){ Object obj=e.getSource();//獲得事件源if(obj==StartChessJFrame.this.startMenuItem||obj==startButton){ //重新開始//JFiveFrame.this內部類引用外部類System.out.println("重新開始"); chessBoard.restartGame(); } else if (obj==exitMenuItem||obj==exitButton) System.exit(0); else if (obj==backMenuItem||obj==backButton){ System.out.println("悔棋..."); chessBoard.goback(); } } } public static void main(String[] args){ StartChessJFrame f=new StartChessJFrame();//創建主框架f.setVisible(true);//顯示主框架} }

三、總結

1.菜單的設計與實現？
2.鼠標點擊棋盤後，如何繪製棋子？如何為剛下的棋子繪製一個紅色框？
3.棋譜是如何一個數據結構？

以上就是本文的全部內容，希望對大家學習java程序設計有所幫助。
