蓝桥杯密室逃脱游戏Java代码及思路

密室逃脱游戏是一种智力类的游戏，需要玩家通过找寻线索、解密谜题等方式逃离密室。下面是一份Java实现的密室逃脱游戏代码及思路。

思路：

1. 定义一个房间类 Room，其中包括房间名称、房间描述、房间物品等属性。
2. 定义一个游戏类 Game，其中包括游戏开始、游戏结束、房间切换等方法。
3. 在 Game 类中定义一个当前房间变量 currentRoom，表示当前所处的房间。
4. 设计游戏的交互界面，通过 Scanner 类获取玩家输入的指令。
5. 根据不同指令执行相应的操作，如查看当前房间描述、查看当前房间物品、移动到相邻房间等。

代码实现：

Room 类：

public class Room {
    private String name; // 房间名称
    private String description; // 房间描述
    private HashMap<String, Item> items; // 房间物品

    public Room(String name, String description) {
        this.name = name;
        this.description = description;
        items = new HashMap<>();
    }

    public String getName() {
        return name;
    }

    public String getDescription() {
        return description;
    }

    public void addItem(Item item) {
        items.put(item.getName(), item);
    }

    public void removeItem(Item item) {
        items.remove(item.getName());
    }

    public Item getItem(String name) {
        return items.get(name);
    }

    public String getItemList() {
        String itemList = "Room contains:";
        for (String itemName : items.keySet()) {
            itemList += " " + itemName;
        }
        return itemList;
    }
}

Game 类：

import java.util.HashMap;
import java.util.Scanner;

public class Game {
    private HashMap<String, Room> rooms; // 所有房间
    private Room currentRoom; // 当前房间

    public Game() {
        rooms = new HashMap<>();
        createRooms();
    }

    private void createRooms() {
        Room livingRoom = new Room("Living Room", "You are in the living room. There is a sofa and a TV.");
        Room bedroom = new Room("Bedroom", "You are in the bedroom. There is a bed and a closet.");
        Room kitchen = new Room("Kitchen", "You are in the kitchen. There is a stove and a fridge.");
        Room bathroom = new Room("Bathroom", "You are in the bathroom. There is a toilet and a shower.");

        livingRoom.addItem(new Item("remote", "A TV remote."));
        bedroom.addItem(new Item("key", "A key to the front door."));
        kitchen.addItem(new Item("knife", "A sharp knife."));
        bathroom.addItem(new Item("towel", "A clean towel."));

        livingRoom.setExit("north", bedroom);
        livingRoom.setExit("east", kitchen);
        bedroom.setExit("south", livingRoom);
        kitchen.setExit("west", livingRoom);
        kitchen.setExit("south", bathroom);
        bathroom.setExit("north", kitchen);

        currentRoom = livingRoom;
    }

    public void start() {
        System.out.println("Welcome to the escape room! Type 'help' for instructions.");
        Scanner scanner = new Scanner(System.in);
        while (true) {
            System.out.println(currentRoom.getDescription());
            System.out.println(currentRoom.getItemList());
            System.out.print("> ");
            String line = scanner.nextLine();
            String[] words = line.split(" ");
            if (words[0].equals("help")) {
                printHelp();
            } else if (words[0].equals("go")) {
                goRoom(words[1]);
            } else if (words[0].equals("look")) {
                System.out.println(currentRoom.getItemList());
            } else if (words[0].equals("take")) {
                takeItem(words[1]);
            } else if (words[0].equals("use")) {
                useItem(words[1]);
            } else if (words[0].equals("quit")) {
                System.out.println("Game over.");
                break;
            }
        }
        scanner.close();
    }

    private void printHelp() {
        System.out.println("Type 'go [direction]' to move to a different room.");
        System.out.println("Type 'look' to see the items in the room.");
        System.out.println("Type 'take [item]' to take an item from the room.");
        System.out.println("Type 'use [item]' to use an item in your inventory.");
        System.out.println("Type 'quit' to end the game.");
    }

    private void goRoom(String direction) {
        Room nextRoom = currentRoom.getExit(direction);
        if (nextRoom == null) {
            System.out.println("You cannot go that way.");
        } else {
            currentRoom = nextRoom;
        }
    }

    private void takeItem(String itemName) {
        Item item = currentRoom.getItem(itemName);
        if (item == null) {
            System.out.println("That item is not in this room.");
        } else {
            currentRoom.removeItem(item);
            System.out.println("You have taken the " + itemName + ".");
        }
    }

    private void useItem(String itemName) {
        switch (itemName) {
            case "remote":
                System.out.println("You turn on the TV, but there is nothing interesting on.");
                break;
            case "key":
                System.out.println("You unlock the front door and escape!");
                System.out.println("Congratulations, you win!");
                System.exit(0);
                break;
            case "knife":
                System.out.println("You cut yourself and lose 1 health point.");
                break;
            case "towel":
                System.out.println("You dry yourself off.");
                break;
            default:
                System.out.println("You cannot use that item.");
        }
    }
}

Item 类：

public class Item {
    private String name; // 物品名称
    private String description; // 物品描述

    public Item(String name, String description) {
        this.name = name;
        this.description = description;
    }

    public String getName() {
        return name;
    }

    public String getDescription() {
        return description;
    }
}

运行游戏：

public class Main {
    public static void main(String[] args) {
        Game game = new Game();
        game.start();
    }
}

输出结果：
