javafx实现五子棋游戏

需求描述

一个五子棋游戏，能实现双方黑白对决，当一方获胜时给出提示信息，利用gui界面实现

项目结构如下图

一、实体

fivechess类

• 提供五子棋实体包含的所有信息
• 判断游戏是否结束
• play方法改变chess[][]棋盘中的数据
  

package entity;


import javafx.scene.control.alert;

public class fivechess{

 public double getwidth() {
 return width;
 }

 public void setwidth(double width) {
 this.width = width;
 }

 public double getheight() {
 return height;
 }

 public void setheight(double height) {
 this.height = height;
 }

 public double getcelllen() {
 return celllen;
 }

 public void setcelllen(double celllen) {
 this.celllen = celllen;
 }

 /**

 * 维度

 */

 private int n;

 private double width;

 private double height;

 private double celllen;

 private char currentside='b';

 public char getflag() {
 return flag;
 }

 private char flag=' ';

 private char[][] chess;

 public char[][] getchess() {
 return chess;
 }

 public void setchess(char[][] chess) {
 this.chess = chess;
 }

 public char getcurrentside() {
 return currentside;
 }

 public void setcurrentside(char currentside) {
 this.currentside = currentside;
 }


 //其他请补充

 public fivechess(double width,double height,double celllen){
 this.width=width;
 this.height=height;
 this.celllen=celllen;
 chess=new char[(int)height][(int)width];
 for(int i=0;i<height;i++)
 for(int j=0;j<width;j++)
 chess[i][j]=' ';
 }


 public void play(int x,int y){

 //将当前的棋子放置到（x,y）
 if(chess[x][y]==' '){
 chess[x][y]=currentside;
 if(!judgegame(x,y,currentside)){
 //游戏结束弹出信息框
 alert alert = new alert(alert.alerttype.information);
 alert.settitle("五子棋游戏");
 alert.setheadertext("提示信息");
 alert.setcontenttext(currentside+"方取得胜利！");

 alert.showandwait();
 }
 changeside();
 }
 }


 public void changeside(){

 //更换下棋方

 setcurrentside(currentside=='b'?'w':'b');

 }


 public boolean judgegame(int row, int col, char chesscolor){

 //判断游戏是否结束
 if(rowjudge(row,col,chesscolor)&&coljudge(row,col,chesscolor)&&maindiagonaljudge(row,col,chesscolor)&&deputydiagonaljudge(row,col,chesscolor))
 return true;
 return false;


 }

 public boolean rowjudge(int row,int col,char chesscolor){
 //判断一行是否五子连线
 int count=0;
 for(int j=col;j<width;j++){
 if(chess[row][j]!=chesscolor)
 break;
 count++;
 }
 for(int j=col-1;j>=0;j--){
 if(chess[row][j]!=chesscolor)
  break;
 count++;
 }
 if(count>=5)
 return false;
 return true;
 }

 public boolean coljudge(int row,int col,char chesscolor){
 //判断一列是否五子连线
 int count=0;
 for(int i=row;i<height;i++){
 if(chess[i][col]!=chesscolor)
  break;
 count++;
 }
 for(int i=row-1;i>=0;i--){
 if(chess[i][col]!=chesscolor)
 break;
 count++;
 }
 if(count>=5)
 return false;

 return true;
 }


 public boolean maindiagonaljudge(int row,int col,char chesscolor){
 //判断主对角线是否五子连线
 int count=0;
 for(int i=row,j=col;i<height&&j<width;i++,j++){
 if(chess[i][j]!=chesscolor)
  break;
 count++;
 }


 for(int i=row-1,j=col-1;i>=0&&j>=0;i--,j--){
 if(chess[i][j]!=chesscolor)
 break;
 count++;
 }

 if(count>=5)
 return false;

 return true;
 }


 public boolean deputydiagonaljudge(int row,int col,char chesscolor){
 //判断副对角线是否五子连线
 int count=0;
 for(int i=row,j=col;i>=0&&j<width;i--,j++){
 if(chess[i][j]!=chesscolor)
 break;

 count++;
 }

 for(int i=row+1,j=col-1;i<height&&j>=0;i++,j--){
 if(chess[i][j]!=chesscolor)
 break;

 count++;
 }


 if(count>=5)
 return false;

 return true;
 }
}

二、视图

chesspane类继承pane类实现棋盘和五子棋的绘制

package view;


import entity.fivechess;
import javafx.scene.canvas.canvas;
import javafx.scene.canvas.graphicscontext;

import javafx.scene.layout.pane;
import javafx.scene.paint.color;


public class chesspane extends pane {
 public canvas getcanvas() {
 return canvas;
 }

 public canvas canvas;

 public graphicscontext getgc() {
 return gc;
 }

 public graphicscontext gc;

 public fivechess getfivechess() {
 return fivechess;
 }

 public void setfivechess(fivechess fivechess) {
 this.fivechess = fivechess;
 }

 public fivechess fivechess;


 public chesspane(fivechess fivechess){
 this.fivechess=fivechess;
 double cell=fivechess.getcelllen();
 drawpane(cell);
 drawchess(cell);
 getchildren().add(canvas);
 }

 public void drawpane(double cell){
 canvas = new canvas(800,700);
 gc = canvas.getgraphicscontext2d();

 gc.clearrect(0,0,canvas.getwidth(),canvas.getheight());

 //绘制棋盘
 gc.setstroke(color.black);

 for(int i=0;i<fivechess.getwidth();i++)
 for(int j=0;j<fivechess.getheight();j++){
 gc.strokerect(100+i*cell,100+cell*j,cell,cell);//清理一个矩形取区域的内容
 }

 }

 public void drawchess(double cell){

 char[][] chess=fivechess.getchess();
 for(int i=0;i<fivechess.getheight();i++)
 for(int j=0;j<fivechess.getwidth();j++){
 if(chess[i][j]=='b'){
  gc.setfill(color.black);//设置填充色
  gc.filloval(100+i*cell-cell/2,100+j*cell-cell/2,cell,cell);
 }
 else if(chess[i][j]=='w'){
  gc.setfill(color.white);

  gc.filloval(100+i*cell-cell/2,100+j*cell-cell/2,cell,cell);//填充椭圆
  gc.strokeoval(100+i*cell-cell/2,100+j*cell-cell/2,cell,cell);//绘制轮廓
 }
 }

 }

}

三、控制器

playaction类继承自事件处理器eventhandler并传递的参数是鼠标事件，表示接受鼠标点击面板事件

package controller;

import entity.fivechess;
import javafx.event.eventhandler;
import javafx.scene.control.alert;
import javafx.scene.input.mouseevent;
import view.chesspane;

public class playaction implements eventhandler<mouseevent> {

 /**fivechess表示五子棋游戏模型*/

 private fivechess fivechess;

 /**chesspane表示五子棋显示面板*/

 private chesspane chesspane;


 public playaction(fivechess fivechess,chesspane chesspane){
 this.chesspane=chesspane;

 this.fivechess = fivechess;

 }

 @override

 public void handle(mouseevent event) {

 //处理鼠标点击事件
 double cell=fivechess.getcelllen();

 //event.getx()获取鼠标点击x坐标，返回double类型
 double x=event.getx();
 double y=event.gety();

 int i=(int)((x-100+cell/2)/cell);
 int j=(int)((y-100+cell/2)/cell);

 system.out.println(i+" "+j);
 fivechess.play(i,j);
 chesspane.drawchess(cell);
 if(!fivechess.judgegame(i,j,fivechess.getcurrentside()=='b'?'w':'b')){
 alert alert = new alert(alert.alerttype.information);
 alert.settitle("五子棋游戏");
 alert.setheadertext("提示信息");
 alert.setcontenttext((fivechess.getcurrentside()=='b'?"白":"黑")+"方取得胜利！");
 alert.showandwait();
 }

 }

}

四、测试

import controller.playaction;
import entity.fivechess;
import javafx.application.application;
import javafx.scene.scene;
import javafx.scene.control.alert;
import javafx.stage.stage;
import view.chesspane;

import javax.print.attribute.standard.fidelity;

public class test extends application {

 public static void main(string[] args) {
 launch(args);
 }


 @override
 public void start(stage primarystage) {
 fivechess fivechess = new fivechess(20,20,28.0);
 chesspane chesspane=new chesspane(fivechess);

 chesspane.setonmouseclicked(new playaction(fivechess,chesspane));//事件源绑定处理器

 scene scene=new scene(chesspane,800,700);
 primarystage.setscene(scene);
 primarystage.settitle("五子棋游戏");
 primarystage.show();

 }
}
