Java实现一个简单的两人五子棋游戏(六) 行棋方变换

1）选择棋子

✔️

2）画棋子

✔️

3）判断胜负

✔️

4）交换行棋方

目标

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-blackprivate 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<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;}}}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<ROWS+1;i++){for(int j=0;j<ROWS+1;j++){//横向查找if(chessStatus[i][j]!=null&&chessStatus[i][j].getPlaced()==true){int matchColor = chessStatus[i][j].getColor();//向右侧查找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+" 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<ROWS+1;i++){for(int j=0;j<ROWS+1;j++){//纵向if(chessStatus[i][j]!=null&&chessStatus[i][j].getPlaced()==true){int matchColor = chessStatus[i][j].getColor();//向下查找，左上角为坐标原点，y轴正方向向下for(int n=1;n<=4;n++){if((j+n>=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);if(chessStatus[i][j].matchCount==5){return true;}}else{break;}}}//向上查找for(int n=1;n<=4;n++){if((j-n>=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+" "+"left count++:"+(i)+" "+(j-n)+" count:"+chessStatus[i][j].matchCount);if(chessStatus[i][j].matchCount==5){return true;}}else{if(chessStatus[i][j-n]!=null){chessStatus[i][j].matchCount = 1;}break;}}}chessStatus[i][j].matchCount=1;//refresh count}}}//方向：左上右下for(int i=0;i<ROWS+1;i++){for(int j=0;j<ROWS+1;j++){//左上if(chessStatus[i][j]!=null&&chessStatus[i][j].getPlaced()==true){int matchColor = chessStatus[i][j].getColor();//向下查找，左上角为坐标原点，y轴正方向向下for(int n=1;n<=4;n++){if((j-n>=0)&&(j-n)<=ROWS&&(i-n)>=0&&(i-n)<=ROWS){if(chessStatus[i-n][j-n]!=null&&chessStatus[i-n][j-n].getPlaced()==true&&chessStatus[i-n][j-n].getColor()==matchColor){chessStatus[i][j].matchCount++;System.out.println("pos:"+i+" "+j+" up count++:"+(i-n)+" "+(j-n)+" count:"+chessStatus[i][j].matchCount);if(chessStatus[i][j].matchCount==5){return true;}}else{break;}}}//右下for(int n=1;n<=4;n++){if((j+n>=0)&&(j+n)<=ROWS&&(i+n)>=0&&(i+n)<=ROWS){if(chessStatus[i+n][j+n]!=null&&chessStatus[i+n][j+n].getPlaced()==true&&chessStatus[i+n][j+n].getColor()==matchColor){chessStatus[i][j].matchCount++;System.out.println("pos:"+i+" "+j+" "+"left count++:"+(i+n)+" "+(j+n)+" count:"+chessStatus[i][j].matchCount);if(chessStatus[i][j].matchCount==5){return true;}}else{if(chessStatus[i+n][j+n]!=null){chessStatus[i][j].matchCount = 1;}break;}}}chessStatus[i][j].matchCount=1;//refresh count}}}//方向：左下右上for(int i=0;i<ROWS+1;i++){for(int j=0;j<ROWS+1;j++){//左下if(chessStatus[i][j]!=null&&chessStatus[i][j].getPlaced()==true){int matchColor = chessStatus[i][j].getColor();//向下查找，左上角为坐标原点，y轴正方向向下for(int n=1;n<=4;n++){if((j+n>=0)&&(j+n)<=ROWS&&(i-n)>=0&&(i-n)<=ROWS){if(chessStatus[i-n][j+n]!=null&&chessStatus[i-n][j+n].getPlaced()==true&&chessStatus[i-n][j+n].getColor()==matchColor){chessStatus[i][j].matchCount++;System.out.println("pos:"+i+" "+j+" up count++:"+(i-n)+" "+(j+n)+" count:"+chessStatus[i][j].matchCount);if(chessStatus[i][j].matchCount==5){return true;}}else{break;}}}//右上for(int n=1;n<=4;n++){if((j-n>=0)&&(j-n)<=ROWS&&(i+n)>=0&&(i+n)<=ROWS){if(chessStatus[i+n][j-n]!=null&&chessStatus[i+n][j-n].getPlaced()==true&&chessStatus[i+n][j-n].getColor()==matchColor){chessStatus[i][j].matchCount++;System.out.println("pos:"+i+" "+j+" "+"left count++:"+(i+n)+" "+(j-n)+" count:"+chessStatus[i][j].matchCount);if(chessStatus[i][j].matchCount==5){return true;}}else{if(chessStatus[i+n][j-n]!=null){chessStatus[i][j].matchCount = 1;}break;}}}chessStatus[i][j].matchCount=1;//refresh count}}}return false;}
