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<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：
