用Python写一个地铁跑酷

好的，下面是一个简单的地铁跑酷游戏的 Python 代码示例：

import pygame
import random

pygame.init()

# 游戏窗口大小
WIDTH, HEIGHT = 800, 600
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("Subway Surfers")

# 玩家角色
player_img = pygame.image.load("player.png")
player_rect = player_img.get_rect()
player_rect.bottomleft = (50, HEIGHT - 50)
player_speed = 5

# 障碍物
obstacle_imgs = [pygame.image.load("obstacle1.png"), pygame.image.load("obstacle2.png"), pygame.image.load("obstacle3.png")]
obstacle_rects = []
obstacle_speed = 5
obstacle_spawn_rate = 30
obstacle_spawn_counter = 0

# 分数
score = 0
font = pygame.font.SysFont("Arial", 30)

# 主游戏循环
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # 玩家移动
    keys = pygame.key.get_pressed()
    if keys[pygame.K_UP] and player_rect.top > 0:
        player_rect.top -= player_speed
    if keys[pygame.K_DOWN] and player_rect.bottom < HEIGHT:
        player_rect.bottom += player_speed

    # 障碍物移动和生成
    obstacle_spawn_counter += 1
    if obstacle_spawn_counter >= obstacle_spawn_rate:
        obstacle_spawn_counter = 0
        obstacle_img = random.choice(obstacle_imgs)
        obstacle_rect = obstacle_img.get_rect()
        obstacle_rect.topright = (WIDTH, random.randint(0, HEIGHT - obstacle_rect.height))
        obstacle_rects.append(obstacle_rect)

    for obstacle_rect in obstacle_rects:
        obstacle_rect.left -= obstacle_speed
        if obstacle_rect.right < 0:
            obstacle_rects.remove(obstacle_rect)

        # 碰撞检测
        if player_rect.colliderect(obstacle_rect):
            running = False

        # 计分
        if obstacle_rect.right <= player_rect.left:
            score += 1

    # 显示分数和角色
    screen.fill((255, 255, 255))
    screen.blit(player_img, player_rect)
    for obstacle_rect in obstacle_rects:
        screen.blit(obstacle_img, obstacle_rect)
    score_text = font.render("Score: " + str(score), True, (0, 0, 0))
    screen.blit(score_text, (10, 10))

    pygame.display.update()

pygame.quit()

请注意，这只是一个简单的示例，您可以根据自己的需求进行修改和扩展。同时，您需要自己准备玩家和障碍物的图片，并将其命名为 "player.png"、"obstacle1.png"、"obstacle2.png" 和 "obstacle3.png"。
