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(五) 判断是否有一方胜出；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<rows+1;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<rows+1;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：
