Java实现两人五子棋游戏(五) 判断是否有一方胜出

Java实现两人五子棋游戏(五) 判断是否有一方胜出

之前的两篇文章：java实现两人五子棋游戏(二) 画出棋盘；Java实现两人五子棋游戏(三) 画出棋子；Java实现两人五子棋游戏(四) 落子动作的实现，可以点击查看。

前面我们已经画好了棋盘、棋子并且可以自由的落子了，那么接下来要实现的功能是判断是否有五连珠（暂时不考虑行棋方）。

我们采用遍历棋盘已经落子的位置，查看每个落子点，在它的上下，左右，左下右上，左上右下四个方向的任一方向上是否有五个连续的棋子。

第一步，对棋子类进行改造，之前我们的棋子类只有颜色信息和落子状态，现在要新增一个int型的数据，用于记录遍历过程中当前有几个珠子已知连续。

Chessman.java

package xchen.test.simpleGobang;

public class Chessman {

private int color;//1-white，0-black

private boolean placed = false;

int matchCount = 1;

public Chessman(int color,boolean placed){

this.color=color;

this.placed=placed;

}

public boolean getPlaced() {

return placed;

}

public void setPlaced(boolean placed) {

this.placed = placed;

}

public int getColor() {

return color;

}

public void setColor(int color) {

this.color = color;

}

}

第二步，先从一个方向上判断是否有五连珠，这里采用左右方向作为尝试。

添加了一个isWin函数，用遍历整个棋盘上的有效棋子的方式，来进行胜出判断。

@Override

public void mousePressed(MouseEvent e) {

for(int n=1;n<=4;n++)

}

break;

}

}

}

chessStatus[i][j].matchCount=1;//refresh count

}

}

}

return false;

}

}

第三步，主模块不变，运行测试一下我们的算法是否正确

Main.java

package xchen.test.simpleGobang;

import java.awt.Container;

import javax.swing.JFrame;

import xchen.test.simpleGobang.DrawChessBoard;

public class Main extends JFrame{

private DrawChessBoard drawChessBoard;

public Main() {

drawChessBoard = new DrawChessBoard();

//Frame标题

setTitle("单机五子棋");

Container containerPane =getContentPane();

containerPane.add(drawChessBoard);

}

public static void main(String[] args) {

Main m = new Main();

m.setSize(800, 800);

m.setVisible(true);

}

}
