1. 前言

本文使用 Pygame 实现的简化版扫雷游戏。

如上图所示，游戏包括基本的扫雷功能：生成雷区、左键点击扫雷、右键标记地雷、显示数字提示等。

2. 准备工作

首先，当然要下载pygame 库文件，可以通过下面命令下载

pip install pygame

在这之前，我们需要提前规划好前期工作，例如游戏窗口多大，生成图形显示的颜色等等。

这里为了方便，我们采用大多数默认的版本，这里生成的格子数量就是（400 / 40）*（400/40），也就是100个窗格

python">import pygame
import random# 初始化 Pygame
pygame.init()# 屏幕设置
SCREEN_WIDTH = 400
SCREEN_HEIGHT = 400
CELL_SIZE = 40
GRID_WIDTH = SCREEN_WIDTH // CELL_SIZE
GRID_HEIGHT = SCREEN_HEIGHT // CELL_SIZE# 颜色定义
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
GRAY = (200, 200, 200)
RED = (255, 0, 0)
GREEN = (0, 255, 0)# 字体设置
font = pygame.font.SysFont("Arial", 20)

如下：

3. 生成雷区

有了窗口格子区域，接下来就可以生成雷区，这里采用random函数随机生成，保证每次打开游戏雷区的位置不一样

python"># 生成雷区
def create_grid(width, height, num_mines):grid = [[0 for _ in range(width)] for _ in range(height)]mines = set()while len(mines) < num_mines:x = random.randint(0, width - 1)y = random.randint(0, height - 1)mines.add((x, y))grid[y][x] = -1  # -1 表示地雷# 计算每个格子周围的地雷数量for y in range(height):for x in range(width):if grid[y][x] == -1:continuecount = 0for dy in [-1, 0, 1]:for dx in [-1, 0, 1]:if 0 <= x + dx < width and 0 <= y + dy < height:if grid[y + dy][x + dx] == -1:count += 1grid[y][x] = countreturn grid, mines

使用 create_grid 函数生成雷区，随机放置地雷，并计算每个格子周围的地雷数量。

4. 鼠标点击扫雷

生成雷区后，下面就是扫雷环节，之前写C语言扫雷，还需要在控制台键入区域。这里可以直接调用鼠标

python"># 绘制格子
def draw_grid():for y in range(GRID_HEIGHT):for x in range(GRID_WIDTH):rect = pygame.Rect(x * CELL_SIZE, y * CELL_SIZE, CELL_SIZE, CELL_SIZE)if revealed[y][x]:if grid[y][x] == -1:pygame.draw.rect(screen, RED, rect)  # 地雷else:pygame.draw.rect(screen, GRAY, rect)if grid[y][x] > 0:text = font.render(str(grid[y][x]), True, BLACK)screen.blit(text, (x * CELL_SIZE + 10, y * CELL_SIZE + 10))else:pygame.draw.rect(screen, WHITE, rect)if flagged[y][x]:pygame.draw.circle(screen, GREEN, rect.center, 10)  # 标记地雷pygame.draw.rect(screen, BLACK, rect, 1)  # 格子边框# 翻开格子
def reveal_cell(x, y):if 0 <= x < GRID_WIDTH and 0 <= y < GRID_HEIGHT and not revealed[y][x]:revealed[y][x] = Trueif grid[y][x] == 0:for dy in [-1, 0, 1]:for dx in [-1, 0, 1]:reveal_cell(x + dx, y + dy)  # 递归翻开空白区域

5. 胜利 or 失败

胜利条件：所有非地雷格子都被翻开时，玩家胜利。

游戏结束显示：
- 如果踩到地雷，显示 "Game Over!"。
- 如果胜利，显示 "You Win!"。

python"># 检查是否胜利
def check_win():for y in range(GRID_HEIGHT):for x in range(GRID_WIDTH):if grid[y][x] != -1 and not revealed[y][x]:return Falsereturn True
