用代码实现Flappy Bird游戏

以下是使用Pygame库实现Flappy Bird游戏的示例代码： ```python import pygame import random # 初始化Pygame pygame.init() # 设置游戏窗口大小和标题 screen_width = 288 screen_height = 512 screen = pygame.display.set_mode((screen_width, screen_height)) pygame.display.set_caption('Flappy Bird') # 加载游戏资源 bg_image = pygame.image.load('assets/background.png').convert() bird_images = [pygame.image.load('assets/bird1.png').convert_alpha(), pygame.image.load('assets/bird2.png').convert_alpha(), pygame.image.load('assets/bird3.png').convert_alpha()] pipe_image = pygame.image.load('assets/pipe.png').convert_alpha() base_image = pygame.image.load('assets/base.png').convert_alpha() # 定义常量 gravity = 0.25 jump_speed = -4 pipe_gap = 100 pipe_speed = -2 base_speed = -1 # 定义类：小鸟、水管、地面 class Bird: def __init__(self): self.x = 50 self.y = 200 self.speed = 0 self.image_index = 0 self.image = bird_images[self.image_index] def jump(self): self.speed = jump_speed def update(self): self.speed += gravity self.y += self.speed if self.y < 0: self.y = 0 if self.y > screen_height - 50: self.y = screen_height - 50 self.image_index += 1 if self.image_index >= len(bird_images): self.image_index = 0 self.image = bird_images[self.image_index] def draw(self): screen.blit(self.image, (self.x, self.y)) class Pipe: def __init__(self, x): self.x = x self.y = random.randint(-200, 0) self.width = pipe_image.get_width() self.height = pipe_image.get_height() self.passed = False def update(self): self.x += pipe_speed def draw(self): screen.blit(pipe_image, (self.x, self.y)) screen.blit(pygame.transform.flip(pipe_image,
