用python写扫雷游戏实例代码分享

下面我为你讲解如何用python写扫雷游戏实例代码：

1. 准备工作

首先，需要安装pygame库，这里以pip安装为例。

pip install pygame

安装完成后，我们可以开始编写代码。

2. 创建游戏窗口

首先，要在pygame中创建游戏窗口。我们可以使用pygame.display.set_mode方法来创建游戏窗口。

import pygame

pygame.init()

# 创建游戏窗口
screen_width = 480
screen_height = 480
screen = pygame.display.set_mode((screen_width, screen_height))

# 游戏主循环
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()

    pygame.display.update()

运行代码，可以看到一个空白的游戏窗口。

3. 绘制游戏界面

接下来，我们向游戏窗口中绘制游戏主界面。需要用到pygame.draw方法来绘制矩形和直线。

import pygame

pygame.init()

# 创建游戏窗口
screen_width = 480
screen_height = 480
screen = pygame.display.set_mode((screen_width, screen_height))

# 绘制游戏界面
block_size = 30
for x in range(0, screen_width, block_size):
    pygame.draw.line(screen, (0, 0, 0), (x, 0), (x, screen_height))
for y in range(0, screen_height, block_size):
    pygame.draw.line(screen, (0, 0, 0), (0, y), (screen_width, y))
pygame.display.update()

# 游戏主循环
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()

    pygame.display.update()

运行代码，可以看到一个由多个格子构成的游戏界面。

4. 添加雷和数字

要添加雷和数字，需要先定义一个格子类，表示每一个格子的状态。

class Block:
    def __init__(self, row, col, block_size):
        self.row = row
        self.col = col
        self.x = col * block_size
        self.y = row * block_size
        self.width = block_size
        self.is_mine = False
        self.num = 0

定义好格子类后，可以在游戏界面上随机生成一些雷，并计算每个格子周围的雷数，并用数字表示出来。

import pygame
import random

pygame.init()

# 创建游戏窗口
screen_width = 480
screen_height = 480
screen = pygame.display.set_mode((screen_width, screen_height))

# 定义格子类
class Block:
    def __init__(self, row, col, block_size):
        self.row = row
        self.col = col
        self.x = col * block_size
        self.y = row * block_size
        self.width = block_size
        self.is_mine = False
        self.num = 0

# 随机生成雷
def create_mines(blocks, num_mines):
    for i in range(num_mines):
        while True:
            block = random.choice(blocks)
            if not block.is_mine:
                block.is_mine = True
                break

# 计算每个格子周围的雷数
def calculate_num(blocks):
    for block in blocks:
        if block.is_mine:
            block.num = -1
        else:
            row = block.row
            col = block.col
            num = 0
            for i in range(row - 1, row + 2):
                for j in range(col - 1, col + 2):
                    if i < 0 or i >= len(blocks) or j < 0 or j >= len(blocks) or (i == row and j == col):
                        continue
                    if blocks[i * len(blocks[0]) + j].is_mine:
                        num += 1
            block.num = num

# 绘制游戏界面
block_size = 30
blocks = []
for row in range(screen_height // block_size):
    for col in range(screen_width // block_size):
        block = Block(row, col, block_size)
        blocks.append(block)
        pygame.draw.rect(screen, (192, 192, 192), (block.x, block.y, block.width, block.width))
create_mines(blocks, 99)
calculate_num(blocks)
for block in blocks:
    if block.is_mine:
        pygame.draw.circle(screen, (255, 0, 0), (block.x + block.width // 2, block.y + block.width // 2), block.width // 2 // 2)
    elif block.num > 0:
        font = pygame.font.Font(None, block.width // 2)
        text = font.render(str(block.num), True, (0, 0, 0))
        text_rect = text.get_rect()
        text_rect.center = (block.x + block.width // 2, block.y + block.width // 2)
        screen.blit(text, text_rect)
pygame.display.update()

# 游戏主循环
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()

    pygame.display.update()

运行代码，可以看到一个有雷和数字的游戏界面。

5. 点击格子

最后，还需要添加点击格子的交互。当点击一个格子时，如果是雷，则游戏结束；否则显示该格子周围的数字。

import pygame
import random

pygame.init()

# 创建游戏窗口
screen_width = 480
screen_height = 480
screen = pygame.display.set_mode((screen_width, screen_height))

# 定义格子类
class Block:
    def __init__(self, row, col, block_size):
        self.row = row
        self.col = col
        self.x = col * block_size
        self.y = row * block_size
        self.width = block_size
        self.is_mine = False
        self.num = 0

# 创建雷
def create_mines(blocks, num_mines):
    for i in range(num_mines):
        while True:
            block = random.choice(blocks)
            if not block.is_mine:
                block.is_mine = True
                break

# 计算数字
def calculate_num(blocks):
    for block in blocks:
        if block.is_mine:
            block.num = -1
        else:
            row = block.row
            col = block.col
            num = 0
            for i in range(row - 1, row + 2):
                for j in range(col - 1, col + 2):
                    if i < 0 or i >= len(blocks) or j < 0 or j >= len(blocks) or (i == row and j == col):
                        continue
                    if blocks[i * len(blocks[0]) + j].is_mine:
                        num += 1
            block.num = num

# 根据数字和雷的位置绘制游戏界面
def draw_screen(blocks):
    screen.fill((192, 192, 192))
    for block in blocks:
        if block.is_mine:
            pygame.draw.circle(screen, (255, 0, 0), (block.x + block.width // 2, block.y + block.width // 2), block.width // 2 // 2)
        elif block.num > 0:
            font = pygame.font.Font(None, block.width // 2)
            text = font.render(str(block.num), True, (0, 0, 0))
            text_rect = text.get_rect()
            text_rect.center = (block.x + block.width // 2, block.y + block.width // 2)
            screen.blit(text, text_rect)
        elif block.num == 0:
            pygame.draw.rect(screen, (255, 255, 255), (block.x, block.y, block.width, block.width), 1)

# 游戏主循环
def main(blocks):
    running = True
    while running:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                running = False
            elif event.type == pygame.MOUSEBUTTONDOWN:
                pos = pygame.mouse.get_pos()
                row = pos[1] // block_size
                col = pos[0] // block_size
                block = blocks[row * len(blocks[0]) + col]
                if block.is_mine:
                    running = False
                elif block.num == 0:
                    block.num = -2
                    queue = [block]
                    while queue:
                        temp = queue.pop(0)
                        row = temp.row
                        col = temp.col
                        for i in range(row - 1, row + 2):
                            for j in range(col - 1, col + 2):
                                if i < 0 or i >= len(blocks) or j < 0 or j >= len(blocks) or (i == row and j == col):
                                    continue
                                next_block = blocks[i * len(blocks[0]) + j]
                                if next_block.num == 0:
                                    queue.append(next_block)
                                next_block.num = next_block.num if next_block.num != -1 else -2
                draw_screen(blocks)
                pygame.display.update()

# 绘制游戏界面
block_size = 30
blocks = []
for row in range(screen_height // block_size):
    for col in range(screen_width // block_size):
        block = Block(row, col, block_size)
        blocks.append(block)
create_mines(blocks, 99)
calculate_num(blocks)
draw_screen(blocks)
pygame.display.update()

main(blocks)

pygame.quit()
exit()

运行代码，按钮点击格子，可以看到数字不断展开，直到没有空格子。如果点到雷，游戏结束。
