Java实现两人五子棋游戏(七) 屏幕提示信息

Java实现两人五子棋游戏(七) 屏幕提示信息

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；Java实现两人五子棋游戏(六) 行棋方变换，可以点击查看。

接下来我们要实现的功能是在有五连珠的时候，在屏幕上提示信息。直接在mousePressed函数的isWin部分使用showMessageDialog即可。

mousePressed函数代码如下：

@Override

//当用户按下鼠标按钮时发生

public void mousePressed(MouseEvent e) {

int point_x=e.getX();

int point_y=e.getY();

int imgWidth = boardImg.getHeight(this);

int imgHeight = boardImg.getWidth(this);

int FWidth = getWidth();

int FHeight= getHeight();

int x=(FWidth-imgWidth)/2;

int y=(FHeight-imgHeight)/2;

int span_x=imgWidth/ROWS;

int span_y=imgHeight/ROWS;

//System.out.println("press");

int status_x = 0;

int status_y = 0;

if(point_x>=x && point_x<=x+imgWidth && point_y>=y && point_y <= y+imgHeight)

{

//System.out.println("合法");

for(int i=0;i

{

if(point_x>=x-chessman_width/2+1+i*span_x)

{

if(point_x<=x+chessman_width/2-1+i*span_x)//如果是width/2会在中间点出现两个匹配值

{

//System.out.println("point x "+i+" "+point_x+" "+(x-chessman_width/2+i*span_x)+" "+(x+chessman_width/2+i*span_x));

status_x = i;

}

}

}

for(int i=0;i

{

if(point_y>=y-chessman_width/2+1+i*span_y)

{

if(point_y <= y+chessman_width/2-1+i*span_y)

{

//System.out.println("point y "+i+" "+point_y+" "+(y-chessman_width/2+1+i*span_y)+" "+(y+chessman_width/2-1+i*span_y));

status_y = i;

}

}

}

if(chessStatus[status_x][status_y]==null||chessStatus[status_x][status_y].getPlaced()==false)

{

Chessman chessman = new Chessman(chessColor, true);

chessStatus[status_x][status_y]=chessman;

System.out.println("chess color:"+chessColor);

if(chessColor==BLACK)

{

chessColor = WHITE;

}else {

chessColor = BLACK;

}

repaint();

//如果胜出，给出提示信息

if(isWin(status_x, status_y, chessStatus))

{

System.out.println("WIN!!!!!");

String winner;

//如果下一子是白色的，那么此次为黑方

if(chessColor == WHITE)

winner = "黑方";

else

winner = "白方";

String mString = String.format("恭喜，%s WIN!!!!!", winner);

JOptionPane.showMessageDialog(this, mString);

}

}

}

}

运行一下：

至此，我们完成了最基本的五子棋功能。下面我将完整代码贴出：

}
