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
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
# 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:
continue
count = 0
for 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 += 1
grid[y][x] = count
return 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
# 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] = True
if 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!"。
# 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 False
return True6. 游戏效果展示
失败：
胜利：
