简单五子棋
棋盘棋子
public void paint(Graphics g) { super.paint(g); //super 相当于是指向当前对象的父类 //画棋盘 for(int i=0;i<15;i++) { g.setColor(Color.blue); g.drawLine(30, 150+i*30, 450, 150+i*30); g.drawLine(30+i*30, 150, 30+i*30, 570); } //画棋子 for(int i=0;i<15;i++) //进行了一次遍历，遍历 chess[][]!=0.画下棋子 for(int j=0;j<15;j++) { if(allChess[i][j]==1) { int ovalX=i*30+20; int ovalY=j*30+140; g.setColor(Color.black); g.fillOval(ovalX,ovalY , 20, 20); g.drawOval(ovalX,ovalY , 20, 20); } if(allChess[i][j]==2) { int ovalX=i*30+20; int ovalY=j*30+140; g.setColor(Color.white); g.fillOval(ovalX,ovalY , 20, 20); g.drawOval(ovalX,ovalY , 20, 20); } } }
鼠标监听
public void mousePressed(MouseEvent e) { if(canPlay) { x=e.getX(); y=e.getY(); if(x>=20 && x<=460 && y>=160 && y<=580) {//判断是否超出棋盘范围 x=(int)(x/30.0-0.5); y=(int)((y-120)/30.0-0.5);//因为要下在相交处，四舍五入确定精度 if(allChess[x][y]==0) { if(isblack) { allChess[x][y]=1; isblack=false;//判定是下哪个棋子 } else { allChess[x][y]=2; isblack=true; } this.repaint();//重绘 if(isWin()) { if(allChess[x][y]==1) JOptionPane.showMessageDialog(this, "黑方获胜"); else JOptionPane.showMessageDialog(this, "白方获胜"); this.canPlay=false;//不能下了 } } } } }
判定
public boolean isWin() { boolean flag=false; int count=1; //四种判定 //1 count=checkCount(0, 1, allChess[x][y]); if(count==5) flag=true; //2 count=checkCount(1, 0, allChess[x][y]); if(count==5) flag=true; //3 count=checkCount(1, 1, allChess[x][y]); if(count==5) flag=true; //4 count=checkCount(1, -1, allChess[x][y]); if(count==5) flag=true; return flag; } public int checkCount(int xChange,int yChange,int color) { int count=1; int tX=xChange; int tY=yChange; while(x+xChange>=0&&x+xChange<=15&&y+yChange>=0&& y+yChange<=15&& color==allChess[x+xChange][y+yChange]) //防止数组越界 { count++; if(xChange!=0) xChange++; if(yChange!=0) { if(yChange>0) yChange++; else yChange--; } //半边的判断 } xChange=tX; yChange=tY;//之所以不用传过来的数据又定义了一个，是防止自加自减出现错误 while(x-xChange>=0&& x-xChange<15&&y-yChange>=0&& y-yChange<15&&color==allChess[x-xChange][y-yChange]) { count++; if(xChange!=0) xChange++; if(yChange!=0) { if(yChange>0) yChange++; else yChange--; } //半边的判断 } return count; }
这是一个极简版的五子棋，不能人人，无悔棋，认输等按钮，只能下棋，以后或许会改进的，接下来上源码
