java五子棋小游戏实现代码
前言
之前学完java基础课程,试着简单做了一下java的一个五子棋小游戏,记录下来。
界面
由于直接用的java库中的一些基本控件写的一个GUI,并没有做过多优化,感觉比较丑
下面是界面展示:
黑子先行,但是我这边简化规则,并没有考虑黑子先行的一些禁手。
下面直接贴代码
接口类
我把五子棋界面的一些常量都定义在了这个接口类中,包括棋盘的起始坐标,棋盘线的间距和棋子半径
public interface constant { int[][] chessLocation = new int[15][15]; static final int x = 50; //左上角位置 static final int y = 50; static final int LN = 15; //棋盘一些常量 static final int R = 45; }
实现类
接口
这个类中继承了 constant、MouseListener、ActionListener三个接口
其中:
- constant为自己定义
- MouseListener为鼠标监听
- ActionListener为事件监听
函数
show()绘制窗口基本框架
paint()绘制棋盘网格线和棋子
IsWin()判断输赢的基本逻辑
mouseClicked()获取鼠标位置,判断棋子落点等
actionPerformed()判断鼠标点击哪个按钮(开始游戏or认输or悔棋)执行相应操作

public void ShowUI() { frame.setSize(740, 800); frame.setTitle("五子棋"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//点击关闭结束程序 frame.setLocationRelativeTo(null);//窗口居中 frame.setVisible(true);//窗体可视化 frame.setResizable(false);//窗体大小不可调整 frame.add(this);

chess_y = (Y - 20) / R; if (chessLocation[chess_x][chess_y] == 0) { //存储棋子状态,转换棋子颜色 if (IsBlack == true) { chessLocation[chess_x][chess_y] = 1; IsBlack = false; } else { chessLocation[chess_x][chess_y] = 2; IsBlack = true; } if (IsWin() == 1) { JOptionPane.showMessageDialog(this, "黑棋获胜"); flag = false; } if (IsWin() == 2) { JOptionPane.showMessageDialog(this, "白棋获胜"); flag = false; } repaint(); } } } } @Override public void mousePressed(MouseEvent e) { } @Override public void mouseReleased(MouseEvent e) { } @Override public void mouseEntered(MouseEvent e) { } @Override public void mouseExited(MouseEvent e) { } @Override public void actionPerformed(ActionEvent e) { String buttonName = e.getActionCommand(); if (buttonName.equals("开始游戏") && flag == false) {//开始游戏,棋盘清空 flag = true; for (int i = 0; i < LN; i++) { for (int j = 0; j < LN; j++) { chessLocation[i][j] = 0; } } IsBlack = true; repaint(); } if (buttonName.equals("认输") && flag == true) { flag = false; if (IsBlack) { JOptionPane.showMessageDialog(this, ",白棋认输,黑棋获胜"); } else { JOptionPane.showMessageDialog(this, ",黑棋认输,白棋获胜"); } } if (buttonName.equals("悔棋") && flag == true) { if (chessLocation[chess_x][chess_y] == 1) { JOptionPane.showMessageDialog(this, "黑方悔棋"); } if (chessLocation[chess_x][chess_y] == 2) { JOptionPane.showMessageDialog(this, "白方悔棋"); } chessLocation[chess_x][chess_y] = 0; IsBlack = !IsBlack; repaint(); } } }
其中比较有趣的是五子棋判赢方式,假设棋盘大小15*15,则我只需要判断正中间的13*13d的格子,向两边扩展,判断是否五子连珠。
具体说明代码里都有注释,不多赘述。
主函数类
public class Main_game { public static void main(String[] args) { game_logic start=new game_logic(); start.ShowUI(); } }
总结
实现了五子棋小游戏的基本功能,但是略感粗糙,细节不足。对于基本控件调用一学就会,做一个小的游戏demo这是对流程控制和操作逻辑的训练很有效的一种方式。之前看了别人的代码觉得简单,但是自己写的时候往往逻辑流程难以连续,思维混乱,有些过程只有自己写了才知道其中的坑。
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持我们。
