Java實現(xiàn)兩人五子棋游戲(七) 屏幕提示信息
更新時間：2018年03月27日 09:36:41 作者：v_xchen_v
這篇文章主要為大家詳細(xì)介紹了Java實現(xiàn)兩人五子棋游戲，屏幕提示游戲信息，具有一定的參考價值，感興趣的小伙伴們可以參考一下
之前的兩篇文章：Java實現(xiàn)兩人五子棋游戲(二) 畫出棋盤；Java實現(xiàn)兩人五子棋游戲(三) 畫出棋子；Java實現(xiàn)兩人五子棋游戲(四) 落子動作的實現(xiàn)；Java實現(xiàn)兩人五子棋游戲(六) 行棋方變換，可以點擊查看。
接下來我們要實現(xiàn)的功能是在有五連珠的時候，在屏幕上提示信息。直接在mousePressed函數(shù)的isWin部分使用showMessageDialog即可。
mousePressed函數(shù)代碼如下：
@Override
//當(dāng)用戶按下鼠標(biāo)按鈕時發(fā)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會在中間點出現(xiàn)兩個匹配值
{
//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();
//如果勝出，給出提示信息
if(isWin(status_x, status_y, chessStatus))
{
System.out.println("WIN!!!!!");
String winner;
//如果下一子是白色的，那么此次為黑方
if(chessColor == WHITE)
winner = "黑方";
else
winner = "白方";
String mString = String.format("恭喜，%s WIN!!!!!", winner);
JOptionPane.showMessageDialog(this, mString);
}
}
}
}
運(yùn)行一下：
至此，我們完成了最基本的五子棋功能。下面我將完整代碼貼出：
