Java五子棋游戏 Java初学者之五子棋游戏实现教程
nevertoolate! 人气:0本文为大家分享了Java实现五子棋游戏的具体代码,供大家参考,具体内容如下
1.图形化界面的创建
1.1创建JFrame窗体容器
1)JFrame窗体需要设置基本的大小、布局、默认的关闭方式,以及最重要的设置可见。
1.2在JFrame上添加组件,用来绘制棋盘棋子和游戏操作。
1)棋盘棋子的绘制:自定义一个类去继承JPanel,把绘制棋盘和棋子的方法重写进入paint()方法里,这样当窗体发生变化(放大、缩小、移动等操作时,棋盘棋子不会消失,棋局得以保存)。
2)悔棋、认输等操作通过JButton按钮添加鼠标监听来实现。
2.关键点的实现
(使用六个类实现背后逻辑,UI类,DrawChessBoard类,GameMouse类,QiZi类,Location类以及AI类)。
2.1在棋盘点击的位置绘制棋子
1)给棋盘添加鼠标监听,获取点击位置的坐标
UI类负责初始化1中的图形化界面,并给DrawChessBoard类添加GameMouse类的监听。这样在鼠标点击棋盘时通过重写GameMouse类的mouseClicked(),就可以获取鼠标在棋盘上点击的像素坐标。
2)坐标转化成二位数组中的坐标
保存棋盘上所有棋子位置用到QiZi类中的int[][] memory二维数组,这样把像素坐标转化为二维数组中的坐标,并附上棋子颜色对应的值,就可以保存棋盘上所有棋子的位置。
3)在棋盘上画出棋子
在DrawChessBoard类paint()方法中遍历QiZi类中的int[][] memory二维数组非零值,就可以在相应位置调用画笔方法画出黑白棋子。
2.2判断输赢
1)下完棋子后,将下棋位置保存到QiZi类的int[][] memory二维数组中后,就可以以该点为中心计算其四个方向上连续棋子的数目,达到五个则通过JOptionPane类生成弹窗确定赢家。
2.2悔棋功能和提示最后落子位置功能的实现
1)每次成功下一颗棋子,就可以创建一个保存了棋子坐标的Location对象,并将该对象添加到 QiZi类的ArrayList或者Stack容器当中,当鼠标点击悔棋Button后,清除QiZi类的int[][] memory二维数组相应位置的数值(将之改为0即可),然后棋盘重绘棋子,就可以完成悔棋的效果。
2)同时可以找到容器中最后落子的位置,并在棋盘相应的坐标出画出最后落子提示。
2.3开始、认输的实现
1)开始游戏,即重置游戏,将棋子类的相应属性清零即可,比如int[][] memory二维数组(即棋谱),owener=1(重置为白色),以及清楚棋盘上面的棋子。
2)认输就可以判断当前QiZi.owner的值,来判断输的一方并给出提示即可。
2.4AI的实现
1)默认AI为黑方的情况下,需要在白色方落子之后调用AI下黑色棋子,所以在需要在GameMouse中下白棋的if分支中调用AI方法
2)AI的厉害与否取决于其设计,在这里提供一个思路:设置一个棋型对照表,给不同棋型赋值(如1111,代表白子四连,权重较高),轮到AI时,可以根据该表计算棋盘上每一个空位在八个方向总的权重大小,在权重最大处落子即可。棋型对照表中不同棋的权重设置,可以通过python等分析大量棋局来获取,以此来训练AI,当权重设置越合理,AI就越强。
3.其他功能
下子的动画效果音效等可以通过开辟不同的线程来实现,而网络对战则可增加网络通信相关模块即可。
4.源码
