目录
扫雷是一款单人益智游戏，目的是在不触雷的情况下，揭示所有非雷方块。玩家可以通过点击方块来揭示其内容，如果揭示到雷，游戏结束。在游戏开始前，玩家可以选择游戏难度，包括初级、中级和高级。
代码实现：
首先，我们需要导入必要的模块：
import random import pygame
然后，定义一些常量和变量：
游戏界面尺寸
SCREEN_WIDTH = 400 SCREEN_HEIGHT = 500
方块尺寸
BLOCK_WIDTH = 20 BLOCK_HEIGHT = 20
雷的数量
BOMB_COUNT = {"easy": 10, "medium": 40, "hard": 99}
游戏状态
GAME_START = 0 GAME_RUN = 1 GAME_OVER = 2
接下来，定义我们的主类Minesweeper：
class Minesweeper: def init(self): # 初始化游戏界面和游戏状态 self.screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT)) self.game_state = GAME_START self.clock = pygame.time.Clock() pygame.display.set_caption("Minesweeper")
# 初始化游戏
def init_game(self):
# 初始化地图
self.map = [[0 for i in range(10)] for j in range(10)]
self.bomb_count = BOMB_COUNT[self.difficulty]
self.flag_count = self.bomb_count
self.bomb_location = []
self.left_click_count = 0
# 随机生成地雷
while len(self.bomb_location) < self.bomb_count:
x = random.randint(0, 9)
y = random.randint(0, 9)
if self.map[y][x] == 0:
self.map[y][x] = -1
self.bomb_location.append((x, y))
# 计算每个方块周围的地雷数
for y in range(10):
for x in range(10):
if self.map[y][x] == -1:
continue
count = 0
for yy in range(y - 1, y + 2):
for xx in range(x - 1, x + 2):
if xx < 0 or xx > 9 or yy < 0 or yy > 9:
continue
if self.map[yy][xx] == -1:
count += 1
self.map[y][x] = count
在init_game()函数中，我们首先初始化了地图，然后随机生成地雷，并且计算每个方块周围的地雷数。
接下来，定义一个函数draw_block()，用于绘制方块：
# 绘制方块
def draw_block(self, x, y, value):
if value == -1:
# 绘制雷
pygame.draw.rect(self.screen, (255, 0, 0), (x * BLOCK_WIDTH, y * BLOCK_HEIGHT, BLOCK_WIDTH, BLOCK_HEIGHT))
else:
# 绘制数字或空白方块
pygame.draw.rect(self.screen, (255, 255, 255), (x * BLOCK_WIDTH, y * BLOCK_HEIGHT, BLOCK_WIDTH, BLOCK_HEIGHT))
if value > 0:
font = pygame.font.SysFont(None, BLOCK_HEIGHT - 2)
text = font.render(str(value), True, (0, 0, 0))
text_rect = text.get_rect()
text_rect.centerx = x * BLOCK_WIDTH + BLOCK_WIDTH / 2
text_rect.centery = y * BLOCK_HEIGHT + BLOCK_HEIGHT / 2
self.screen.blit(text, text_rect)
在主类中，我们还需要定义事件处理函数handle_event()：
# 事件处理函数
def handle_event(self, event):
if event.type == pygame.QUIT:
self.game_state = GAME_OVER
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_ESCAPE:
self.game_state = GAME_OVER
elif event.key == pygame.K_F2:
self.init_game()
elif event.type == pygame.MOUSEBUTTONDOWN:
if self.game_state == GAME_START:
self.game_state = GAME_RUN
if event.button == 1:
# 左键
x, y = event.pos
x = x / BLOCK_WIDTH
y = y / BLOCK_HEIGHT
if self.map[y][x] == -1:
self.game_state = GAME_OVER
else:
self.reveal_block(x, y)
self.left_click_count += 1
elif event.button == 3:
# 右键
x, y = event.pos
x = x / BLOCK_WIDTH
y = y / BLOCK_HEIGHT
if self.map[y][x] == -1:
self.bomb_count += 1
self.flag_count += 1
else:
self.flag_count -= 1
self.map[y][x] = -2 if self.map[y][x] == 0 else 0
在handle_event()函数中，我们处理了游戏中的各种事件，包括鼠标左键点击、鼠标右键点击、键盘按键等。
接下来，我们定义一个函数reveal_block()，用于揭示方块：
# 揭示方块
def reveal_block(self, x, y):
if x < 0 or x > 9 or y < 0 or y > 9:
return
if self.map[y][x] == -1 or self.map[y][x] == -2:
return
if self.map[y][x] > 0:
self.map[y][x] = -2
return
self.map[y][x] = -2
self.reveal_block(x - 1, y)
self.reveal_block(x + 1, y)
self.reveal_block(x, y - 1)
self.reveal_block(x, y + 1)
self.reveal_block(x - 1, y - 1)
self.reveal_block(x + 1, y - 1)
self.reveal_block(x - 1, y + 1)
self.reveal_block(x + 1, y + 1)
在reveal_block()函数中，我们首先检查方块是否是地雷或旗子，如果是，则不做任何操作。如果方块是数字或空白方块，则将其标记为已经揭示，并递归揭示周围的方块。
最后，我们定义一个函数run()，用于运行游戏：
# 运行游戏
def run(self):
while self.game_state != GAME_OVER:
self.clock.tick(60)
for event in pygame.event.get():
self.handle_event(event)
self.screen.fill((0, 0, 0))
if self.game_state == GAME_RUN:
for y in range(10):
for x in range(10):
self.draw_block(x, y, self.map[y][x])
if self.left_click_count == 100 - self.bomb_count:
self.game_state = GAME_OVER
font = pygame.font.SysFont(None, 30)
text = font.render("You Win!", True, (0, 255, 0))
text_rect = text.get_rect()
text_rect.centerx = SCREEN_WIDTH / 2
text_rect.centery = SCREEN_HEIGHT - 80
self.screen.blit(text, text_rect)
elif self.game_state == GAME_START:
font = pygame.font.SysFont(None, 30)
text = font.render("Press any key to start game", True, (255, 255, 255))
text_rect = text.get_rect()
text_rect.centerx = SCREEN_WIDTH / 2
text_rect.centery = SCREEN_HEIGHT - 80
self.screen.blit(text, text_rect)
else:
# GAME_OVER
font = pygame.font.SysFont(None, 30)
text = font.render("Game Over! Press F2 to restart", True, (255, 0, 0))
text_rect = text.get_rect()
text_rect.centerx = SCREEN_WIDTH / 2
text_rect.centery = SCREEN_HEIGHT - 80
self.screen.blit(text, text_rect)
pygame.display.update()
最后，我们创建一个Minesweeper对象并运行游戏：
if name == "main": pygame.init() minesweeper = Minesweeper() minesweeper.difficulty = "easy" # 初级 minesweeper.init_game() minesweeper.run() pygame.quit()
