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(); }}
