  继续学习JAVA,做出了城堡游戏

点击查看代码

//Room
package castleV3;

import java.util.HashMap;

public class Room {
	
    private  String description;
    private HashMap<String ,Room> exits =new HashMap<String ,Room>();

    public Room(String description)     {
        this.description = description;
    }
    
    public void  setExit(String dir ,Room room){
    	exits.put(dir, room);
    }

    @Override
    public String toString()
    {
        return description;
    }
    
    public  String getExitDesc() {

    	StringBuffer sb=new  StringBuffer();
    	for (String dir: exits.keySet()) {
    		sb.append(dir);
    		sb.append(" ");
    	}
    	return sb.toString();
    }

    public Room  getExit(String direction) {
    	return	exits.get(direction);
    }
}
//Handlerhelp
package castleV3;

public class HandlerHelp extends Handler {
	
	   public HandlerHelp(Game game ) {
			  super(game);
		   }
	   
	@Override
	public void docmd(String word) {
			System.out.println("迷路了吗？ 你可以做的命令有 ：go  bye help");
			System.out.println("如 \t go east");
	}
}

//Handlergo
package castleV3;

public class HandlerGo extends Handler  {
	   public HandlerGo(Game game ) {
			  super(game);
		   }

	@Override
	public void docmd(String word) {
		game.goRoom(word);
	}   
}

//Handlerbye
package castleV3;

public class HandlerBye extends Handler {

	   public HandlerBye(Game game ) {
		  super(game);
	   }
	@Override
	public boolean isBye() {
		return true;
	}
}

//Handler
package castleV3;

public class Handler {
	
	protected Game game;
	
	   public Handler(Game game ) {
		   this.game=game;
	   }
	   
		public void docmd(String word) {
			
		}
		
		public boolean isBye() {
			return false;
		}

}

//Game
package castleV3;
//V2 基础上 增加框架＋数据来提高拓展性
import java.util.HashMap;
import java.util.Scanner;

public class Game {
    private Room currentRoom;
    private HashMap<String,Handler>handlers= new HashMap<String,Handler>();        
    public Game() 
    {
    	handlers.put("bye", new HandlerBye(this));
    	handlers.put("help", new HandlerHelp(this));
    	handlers.put("go", new HandlerGo(this));
    
        createRooms();
    }

    private void createRooms()
    {
        Room outside, lobby, pub, study, bedroom;
      
        //	制造房间
        outside = new Room("城堡外");
        lobby = new Room("大堂");
        pub = new Room("小酒吧");
        study = new Room("书房");
        bedroom = new Room("卧室");
        
        //	初始化房间的出口
        outside.setExit("east", lobby);
        outside.setExit("south",study);
        outside.setExit("west",pub);

//        增加 拓展
        lobby.setExit("up",  pub);
        pub.setExit("down", lobby);
        
        currentRoom = outside;  //	从城堡门外开始
    }

    private void printWelcome() {
        System.out.println();
        System.out.println("欢迎来到城堡！");
        System.out.println("这是一个超级无聊的游戏。");
        System.out.println("如果需要帮助，请输入 'help' 。");
        System.out.println();
        showPrompt(); 
    }

    	public void showPrompt() {
    		 System.out.println("现在你在" + currentRoom);
    	        System.out.print("出口有：");
    	 System.out.println(currentRoom.getExitDesc());
    	}
    	
    // 以下为用户命令
    public  void goRoom(String direction) 
    {
        Room nextRoom = currentRoom.getExit(direction);
       
        if (nextRoom == null) {
            System.out.println("那里没有门！");
        }
        else {
            currentRoom = nextRoom;
            showPrompt();
        }
    }
    
    public void play() {
    	Scanner in = new Scanner(System.in);
        while ( true ) {
    		String line = in.nextLine();
    		String[] words = line.split(" ");
    		Handler handler=handlers.get(words[0]);
    		String value="";
    		if(words.length>1)  		
    			value=words[1];
    		if (handler!=null) {
    			handler.docmd(value);
    			if(handler.isBye()) {
    				break;
    				}
    			}
        }
        in.close();
    }
    
	public static void main(String[] args) {
		
		Game game = new Game();
		game.printWelcome();
		game.play();
        System.out.println("感谢您的光临。再见！");
	}
}
