帮我写WUMPUS代码

Wumpus World是一个经典的文本冒险游戏，玩家在一个洞穴地图中寻找金子并避免遇到恐怖的瓦普斯（一种会发射毒气和刺人的怪物）。以下是一个简单的Wumpus World的Python代码版本，这个版本基于命令行交互：

import random

class Cave:
    def __init__(self, width, height):
        self.width = width
        self.height = height
        self.map = [[' ' for _ in range(width)] for _ in range(height)]
        self.wumpus = {'x': None, 'y': None}
        self.gold = {'x': None, 'y': None}

    def place_wumpus(self):
        x, y = random.randint(0, self.width - 1), random.randint(0, self.height - 1)
        while [x, y] == self.gold['x'], [x, y] == self.wumpus['x'] or self.map[y][x] != ' ': 
            x, y = random.randint(0, self.width - 1), random.randint(0, self.height - 1)
        self.wumpus['x'], self.wumpus['y'] = x, y
        self.map[y][x] = 'W'

    def place_gold(self):
        self.gold['x'], self.gold['y'] = random.randint(0, self.width - 1), random.randint(0, self.height - 1)
        while self.map[self.gold['y']][self.gold['x']] != ' ': 
            self.gold['x'], self.gold['y'] = random.randint(0, self.width - 1), random.randint(0, self.height - 1)
        self.map[self.gold['y']][self.gold['x']] = 'G'

    def move_player(self, direction):
        if direction == 'u':
            player_y = max(0, self.player['y'] - 1)
        elif direction == 'd':
            player_y = min(self.height - 1, self.player['y'] + 1)
        elif direction == 'l':
            player_x = max(0, self.player['x'] - 1)
        elif direction == 'r':
            player_x = min(self.width - 1, self.player['x'] + 1)

        if self.map[player_y][player_x] != 'P' and (self.wumpus['x'], self.wumpus['y']) != (player_x, player_y):
            self.player['y'], self.player['x'] = player_y, player_x
            return True
        else:
            print("Invalid move.")
            return False

# 示例游戏
cave = Cave(5, 5)
cave.place_wumpus()
cave.place_gold()
cave.player = {'x': 0, 'y': 0}  # 初始化玩家位置
while True:
    print("You are at ({}, {}).".format(cave.player['x'], cave.player['y']))
    direction = input("Enter a direction (u/d/l/r): ")
    if cave.move_player(direction):
        if cave.map[cave.player['y']][cave.player['x']] == 'G':
            print("You found gold!")
            break
        elif cave.map[cave.player['y']][cave.player['x']] == 'W':
            print("A wumpus shot you!")
            break
