Java实现两人五子棋游戏(六) 行棋方变换

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，可以点击查看。

前面我们已经画好棋盘和棋子，并可以自由落子，且可以判断棋盘中是否有五连珠。接下来的工作是，每次落子后交换行棋方（即将下一棋子颜色由白->黑或黑->白），并将胜出判断增加颜色判断条件（棋盘上存在五连珠->棋盘上存在同色的五连珠）。

主模块Main.java和棋子类Chessman.java不变，我们要对DrawChessBoard.java中的落子函数mousePressed和五连珠判断函数isWin做一下调整。

Main.java

package xchen.test.simpleGobang; 
 
import java.awt.Container; 
import javax.swing.Jframe; 
 
import xchen.test.simpleGobang.DrawChessBoard; 
 
public class Main extends Jframe{ 
  private DrawChessBoard drawChessBoard; 
  public Main() {    
    drawChessBoard = new DrawChessBoard(); 
     
    //frame标题 
    setTitle("单机五子棋"); 
     
    Container containerPane =getContentPane(); 
    containerPane.add(drawChessBoard);    
  } 
  public static void main(String[] args) { 
    Main m = new Main(); 
    m.setSize(800, 800); 
    m.setVisible(true); 
  } 
} 

Chessman.java

package xchen.test.simpleGobang; 
 
public class Chessman { 
  private int color;//1-white，0-black 
  private boolean placed = false; 
  int matchCount = 1; 
   
  public Chessman(int color,boolean placed){ 
    this.color=color; 
    this.placed=placed; 
  } 
   
  public boolean getPlaced() { 
    return placed; 
  } 
 
  public void setPlaced(boolean placed) { 
    this.placed = placed; 
  } 
 
  public int getColor() { 
    return color; 
  } 
 
  public void setColor(int color) { 
    this.color = color; 
  } 
} 

第一步，修改mousePressed函数，使得每次落子后，都将行棋方让给对家（即每次落子都改变棋子颜色）

DrawChessBoard.java中的mousePressed函数部分，只要每次都修改chessColor的值即可。

@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=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=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; 
 } 
      } 
    } 
     
    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(); 
    if(isWin(status_x, status_y, chessStatus)) 
    { 
      System.out.println("WIN!!!!!"); 
    } 
  } 
} 

运行一下

第二步，将胜出判断增加颜色判断条件（棋盘上存在五连珠->棋盘上存在同色的五连珠）

在isWin函数的判断条件上，加上对Chessman.getColor的颜色判断

isWin函数代码

boolean isWin(int point_x,int point_y,Chessman[][] cm) 
{   
  for(int i=0;i=0)&&(i+n)<=ROWS) 
   { 
     if(chessStatus[i+n][j]!=null&&chessStatus[i+n][j].getPlaced()==true&&chessStatus[i+n][j].getColor()==matchColor) 
     { 
chessStatus[i][j].matchCount++; 
System.out.println("pos:"+i+" "+j+" right count++:"+(i+n)+" "+j+" count:"+chessStatus[i][j].matchCount); 
if(chessStatus[i][j].matchCount==5) 
{ 
  return true; 
} 
     }else 
     { 
break; 
     }   
   } 
 } 
 //向左侧查找 
 for(int n=1;n<=4;n++) 
 { 
   if((i-n>=0)&&(i-n)<=ROWS) 
   { 
     if(chessStatus[i-n][j]!=null&&chessStatus[i-n][j].getPlaced()==true&&chessStatus[i-n][j].getColor()==matchColor) 
     { 
chessStatus[i][j].matchCount++; 
System.out.println("pos:"+i+" "+j+" "+"left count++:"+(i-n)+" "+j+" count:"+chessStatus[i][j].matchCount); 
if(chessStatus[i][j].matchCount==5) 
{ 
  return true; 
} 
     }else 
     { 
if(chessStatus[i-n][j]!=null) 
{ 
  chessStatus[i][j].matchCount = 1; 
} 
break; 
     } 
   } 
 } 
 chessStatus[i][j].matchCount=1;//refresh count 
      } 
    } 
  } 
 
  for(int i=0;i=0)&&(j+n)<=ROWS) 
   { 
     if(chessStatus[i][j+n]!=null&&chessStatus[i][j+n].getPlaced()==true&&chessStatus[i][j+n].getColor()==matchColor) 
     { 
chessStatus[i][j].matchCount++; 
System.out.println("pos:"+i+" "+j+" up count++:"+(i)+" "+(j+n)+" count:"+chessStatus[i][j].matchCount);
