python拼图游戏 计时和计步功能的实现代码

以下是一个简单的Python拼图游戏的计时和计步功能实现代码：

import pygame
import random

# 初始化游戏
pygame.init()

# 创建游戏窗口
WIDTH, HEIGHT = 640, 480
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("拼图游戏")

# 加载拼图图片
image = pygame.image.load("puzzle.jpg")
image_width, image_height = image.get_rect().size

# 将图片切成多个小块
block_size = 80
blocks = []
for y in range(0, image_height, block_size):
    for x in range(0, image_width, block_size):
        rect = pygame.Rect(x, y, block_size, block_size)
        blocks.append(image.subsurface(rect))

# 随机打乱小块顺序
random.shuffle(blocks)

# 将小块排列成拼图
rows = cols = int(WIDTH / block_size)
board = [[None for _ in range(cols)] for _ in range(rows)]
for i, block in enumerate(blocks):
    row = i // cols
    col = i % cols
    board[row][col] = block

# 游戏循环
clock = pygame.time.Clock()
start_time = pygame.time.get_ticks()
steps = 0
while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()
        elif event.type == pygame.MOUSEBUTTONDOWN:
            mx, my = pygame.mouse.get_pos()
            col = mx // block_size
            row = my // block_size
            if row < rows-1 and board[row+1][col] is None:
                board[row][col], board[row+1][col] = board[row+1][col], board[row][col]
                steps += 1
            elif row > 0 and board[row-1][col] is None:
                board[row][col], board[row-1][col] = board[row-1][col], board[row][col]
                steps += 1
            elif col < cols-1 and board[row][col+1] is None:
                board[row][col], board[row][col+1] = board[row][col+1], board[row][col]
                steps += 1
            elif col > 0 and board[row][col-1] is None:
                board[row][col], board[row][col-1] = board[row][col-1], board[row][col]
                steps += 1

    # 绘制游戏界面
    screen.fill((255, 255, 255))
    for row in range(rows):
        for col in range(cols):
            if board[row][col] is not None:
                screen.blit(board[row][col], (col*block_size, row*block_size))
    time_passed = pygame.time.get_ticks() - start_time
    time_text = f"Time: {time_passed/1000:.1f} s"
    steps_text = f"Steps: {steps}"
    font = pygame.font.Font(None, 30)
    time_surf = font.render(time_text, True, (0, 0, 0))
    steps_surf = font.render(steps_text, True, (0, 0, 0))
    screen.blit(time_surf, (10, 10))
    screen.blit(steps_surf, (10, 40))

    pygame.display.flip()
    clock.tick(60)

这个代码使用了Pygame库来创建游戏窗口、处理事件和绘制游戏界面。计时和计步功能是通过使用`pygame.time.get_ticks()`函数来获取游戏运行时间，以及记录玩家移动的步数来实现的。在游戏界面的左上角和左下角分别显示了当前的时间和步数。
