写一篇python跑酷小游戏的设计代码

好的，下面是一个简单的 Python 跑酷小游戏的设计代码：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 游戏窗口大小
screen_width = 800
screen_height = 600

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

# 游戏标题
pygame.display.set_caption("Python 跑酷小游戏")

# 游戏背景颜色
bg_color = (255, 255, 255)

# 游戏字体
font = pygame.font.SysFont(None, 48)

# 玩家图片
player_image = pygame.image.load("player.png").convert_alpha()

# 障碍物图片
obstacle_image = pygame.image.load("obstacle.png").convert_alpha()

# 玩家初始位置
player_x = 100
player_y = screen_height - player_image.get_height() - 50

# 障碍物初始位置
obstacle_x = screen_width
obstacle_y = screen_height - obstacle_image.get_height() - 50

# 玩家移动速度
player_speed = 5

# 障碍物移动速度
obstacle_speed = 10

# 是否游戏结束
game_over = False

# 得分
score = 0


# 绘制玩家
def draw_player(x, y):
    screen.blit(player_image, (x, y))


# 绘制障碍物
def draw_obstacle(x, y):
    screen.blit(obstacle_image, (x, y))


# 显示得分
def show_score(score):
    score_text = font.render("Score: " + str(score), True, (0, 0, 0))
    screen.blit(score_text, (10, 10))


# 游戏主循环
while not game_over:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True

    # 玩家移动
    keys = pygame.key.get_pressed()
    if keys[pygame.K_UP]:
        player_y -= player_speed
    if keys[pygame.K_DOWN]:
        player_y += player_speed

    # 障碍物移动
    obstacle_x -= obstacle_speed
    if obstacle_x < -obstacle_image.get_width():
        obstacle_x = screen_width
        score += 1
        obstacle_speed += 1

    # 碰撞检测
    player_rect = pygame.Rect(player_x, player_y, player_image.get_width(), player_image.get_height())
    obstacle_rect = pygame.Rect(obstacle_x, obstacle_y, obstacle_image.get_width(), obstacle_image.get_height())
    if player_rect.colliderect(obstacle_rect):
        game_over = True

    # 绘制游戏元素
    screen.fill(bg_color)
    draw_player(player_x, player_y)
    draw_obstacle(obstacle_x, obstacle_y)
    show_score(score)
    pygame.display.update()

# 游戏结束
game_over_text = font.render("Game Over", True, (255, 0, 0))
screen.blit(game_over_text, (screen_width // 2 - game_over_text.get_width() // 2, screen_height // 2 - game_over_text.get_height() // 2))
pygame.display.update()

# 等待用户关闭窗口
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()

请注意，这只是一个简单的示例代码，您可以根据自己的需求进行修改和扩展。同时，还需要准备玩家和障碍物的图片素材，以及相应的声音素材等。
