用Python代码写一个扫雷游戏要求使用pygame

好的，以下是一个基本的扫雷游戏的Python代码，使用pygame库实现：

import pygame
import random

# 游戏窗口大小
WINDOW_WIDTH = 800
WINDOW_HEIGHT = 600

# 网格大小
GRID_SIZE = 20

# 地雷数量
MINE_COUNT = 20

# 颜色定义
BLACK = (0, 0, 0)
GRAY = (128, 128, 128)
WHITE = (255, 255, 255)
RED = (255, 0, 0)

# 初始化游戏
pygame.init()

# 创建游戏窗口
screen = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption('扫雷')

# 加载图标
icon = pygame.image.load('mine.png')
pygame.display.set_icon(icon)

# 创建字体
font = pygame.font.Font(None, 30)

# 加载图片
mine_img = pygame.image.load('mine.png')
flag_img = pygame.image.load('flag.png')

# 定义方块类
class Block:
    def __init__(self, x, y):
        self.x = x
        self.y = y
        self.mine = False
        self.revealed = False
        self.flagged = False
        self.adjacent_mines = 0

    # 绘制方块
    def draw(self):
        rect = pygame.Rect(self.x * GRID_SIZE, self.y * GRID_SIZE, GRID_SIZE, GRID_SIZE)
        pygame.draw.rect(screen, GRAY, rect)
        pygame.draw.rect(screen, BLACK, rect, 1)
        if self.revealed:
            if self.mine:
                screen.blit(mine_img, rect)
            else:
                text = font.render(str(self.adjacent_mines), True, BLACK)
                text_rect = text.get_rect()
                text_rect.center = rect.center
                screen.blit(text, text_rect)
        elif self.flagged:
            screen.blit(flag_img, rect)

    # 揭开方块
    def reveal(self):
        if not self.flagged:
            self.revealed = True
            if self.mine:
                return False
            elif self.adjacent_mines == 0:
                for x_offset in range(-1, 2):
                    for y_offset in range(-1, 2):
                        x = self.x + x_offset
                        y = self.y + y_offset
                        if 0 <= x < WINDOW_WIDTH // GRID_SIZE and 0 <= y < WINDOW_HEIGHT // GRID_SIZE:
                            block = blocks[x][y]
                            if not block.revealed:
                                block.reveal()
        return True

# 初始化方块列表
blocks = [[Block(x, y) for y in range(WINDOW_HEIGHT // GRID_SIZE)] for x in range(WINDOW_WIDTH // GRID_SIZE)]

# 放置地雷
mines = []
for i in range(MINE_COUNT):
    while True:
        x = random.randrange(WINDOW_WIDTH // GRID_SIZE)
        y = random.randrange(WINDOW_HEIGHT // GRID_SIZE)
        if not blocks[x][y].mine:
            blocks[x][y].mine = True
            mines.append(blocks[x][y])
            break

# 计算相邻地雷数量
for x in range(WINDOW_WIDTH // GRID_SIZE):
    for y in range(WINDOW_HEIGHT // GRID_SIZE):
        block = blocks[x][y]
        for x_offset in range(-1, 2):
            for y_offset in range(-1, 2):
                if x_offset == 0 and y_offset == 0:
                    continue
                x_adj = x + x_offset
                y_adj = y + y_offset
                if 0 <= x_adj < WINDOW_WIDTH // GRID_SIZE and 0 <= y_adj < WINDOW_HEIGHT // GRID_SIZE:
                    if blocks[x_adj][y_adj].mine:
                        block.adjacent_mines += 1

# 游戏循环
game_over = False
while not game_over:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True
        elif event.type == pygame.MOUSEBUTTONDOWN:
            if event.button == 1:
                x = event.pos[0] // GRID_SIZE
                y = event.pos[1] // GRID_SIZE
                block = blocks[x][y]
                if not block.flagged:
                    if not block.reveal():
                        game_over = True
                        for mine in mines:
                            mine.revealed = True
            elif event.button == 3:
                x = event.pos[0] // GRID_SIZE
                y = event.pos[1] // GRID_SIZE
                block = blocks[x][y]
                block.flagged = not block.flagged
    
    # 绘制界面
    screen.fill(WHITE)
    for x in range(WINDOW_WIDTH // GRID_SIZE):
        for y in range(WINDOW_HEIGHT // GRID_SIZE):
            blocks[x][y].draw()
    pygame.display.flip()

# 退出游戏
pygame.quit()

在运行游戏之前，需要准备两张图片：mine.png 和 flag.png，分别表示地雷和旗帜。将这两张图片放在同级目录下即可。

通过运行该代码，即可启动扫雷游戏，使用鼠标左键揭开方块，使用鼠标右键标记地雷位置。
