写一个python跑酷小游戏

好的，以下是一个基于Python的跑酷小游戏的示例代码：

import pygame
import random

# 初始化Pygame
pygame.init()

# 定义游戏屏幕大小
screen_width = 800
screen_height = 600

# 创建游戏窗口
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("跑酷小游戏")

# 加载游戏资源
player_image = pygame.image.load("player.png").convert_alpha()
bg_image = pygame.image.load("background.png").convert_alpha()
obstacle_image = pygame.image.load("obstacle.png").convert_alpha()

# 定义游戏变量
player_pos = [100, 400]
player_speed = 10
player_jump = False
player_jump_speed = 20
player_gravity = 1

obstacle_pos = [screen_width + 100, 400]
obstacle_speed = 10

score = 0

# 定义游戏函数
def draw_background():
    screen.blit(bg_image, (0, 0))

def draw_player():
    screen.blit(player_image, player_pos)

def draw_obstacle():
    screen.blit(obstacle_image, obstacle_pos)

def update_obstacle():
    global obstacle_pos, score
    obstacle_pos[0] -= obstacle_speed
    if obstacle_pos[0] < -100:
        obstacle_pos[0] = screen_width + 100
        obstacle_pos[1] = random.randint(200, 500)
        score += 1

def check_collision():
    global player_pos, score
    player_rect = pygame.Rect(player_pos[0], player_pos[1], player_image.get_width(), player_image.get_height())
    obstacle_rect = pygame.Rect(obstacle_pos[0], obstacle_pos[1], obstacle_image.get_width(), obstacle_image.get_height())
    if player_rect.colliderect(obstacle_rect):
        score = 0
        player_pos = [100, 400]
        obstacle_pos = [screen_width + 100, 400]

def update_score():
    font = pygame.font.Font(None, 36)
    text = font.render("Score: " + str(score), True, (255, 255, 255))
    screen.blit(text, (screen_width - 150, 20))

# 游戏主循环
running = True
while running:
    # 事件处理
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE and not player_jump:
                player_jump = True

    # 游戏逻辑
    if player_jump:
        player_pos[1] -= player_jump_speed
        player_jump_speed -= player_gravity
        if player_pos[1] > 400:
            player_pos[1] = 400
            player_jump = False
            player_jump_speed = 20

    update_obstacle()
    check_collision()

    # 游戏画面
    draw_background()
    draw_player()
    draw_obstacle()
    update_score()

    # 更新屏幕
    pygame.display.update()

# 退出游戏
pygame.quit()

请注意，此代码仅仅是一个简单的示例，您可以根据自己的需求进行修改和扩展。同时，为了让这个游戏运行起来，您还需要准备好 `player.png`、`background.png` 和 `obstacle.png` 这三个图片资源。
