愤怒的小鸟python代码

这是一个基于 Pygame 的愤怒的小鸟游戏的 Python 代码：

import pygame
import random

pygame.init()

# 游戏窗口大小
WIDTH = 288
HEIGHT = 512
SCREEN = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("Flappy Bird")

# 颜色定义
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
BLUE = (0, 0, 255)
GREEN = (0, 255, 0)
RED = (255, 0, 0)

# 加载图片
BACKGROUND_IMAGE = pygame.image.load("assets/background-day.png").convert()
GROUND_IMAGE = pygame.image.load("assets/base.png").convert()
BIRD_IMAGES = [pygame.image.load("assets/yellowbird-downflap.png").convert_alpha(),
               pygame.image.load("assets/yellowbird-midflap.png").convert_alpha(),
               pygame.image.load("assets/yellowbird-upflap.png").convert_alpha()]

PIPE_IMAGE = pygame.image.load("assets/pipe-green.png").convert()

# 设置帧率
CLOCK = pygame.time.Clock()
FPS = 60

# 鸟类
class Bird(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = BIRD_IMAGES[0]
        self.rect = self.image.get_rect()
        self.rect.centerx = WIDTH // 2
        self.rect.centery = HEIGHT // 2
        self.speed = 0
        self.gravity = 0.5

    def update(self):
        self.speed += self.gravity
        self.rect.centery += self.speed

        if self.rect.bottom >= 400:
            self.rect.bottom = 400

    def jump(self):
        self.speed = -10

# 管道类
class Pipe(pygame.sprite.Sprite):
    def __init__(self, x, y, position):
        super().__init__()

        self.rect.centerx = x
        if position == "top":
            self.image = pygame.transform.flip(self.image, False, True)
            self.rect.bottom = y - 100
        else:
            self.rect.top = y + 100

        self.rect.centerx = x
        self.speed = -2

    def update(self):
        self.rect.centerx += self.speed
        if self.rect.right < 0:
            self.kill()

# 地面类
class Ground(pygame.sprite.Sprite):
    def __init__(self, x):
        super().__init__()
        self.image = GROUND_IMAGE
        self.rect = self.image.get_rect()
        self.rect.x = x
        self.rect.y = 400
        self.speed = -2

    def update(self):
        self.rect.x += self.speed
        if self.rect.right < 0:
            self.rect.x = WIDTH

# 创建精灵组
bird_group = pygame.sprite.Group()
pipe_group = pygame.sprite.Group()
ground_group = pygame.sprite.Group()

# 创建鸟
bird = Bird()
bird_group.add(bird)

# 创建地面
for i in range(2):
    ground = Ground(i * WIDTH)
    ground_group.add(ground)

# 游戏主循环
while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()

        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE:
                bird.jump()

    # 添加管道
    if len(pipe_group) < 3:
        pipe_x = WIDTH + 100
        offset = random.randint(-100, 100)
        pipe_y = HEIGHT / 2 + offset
        top_pipe = Pipe(pipe_x, pipe_y, "top")
        bottom_pipe = Pipe(pipe_x, pipe_y, "bottom")
        pipe_group.add(top_pipe)
        pipe_group.add(bottom_pipe)

    # 更新精灵组
    bird_group.update()
    pipe_group.update()
    ground_group.update()

    # 绘制背景
    SCREEN.blit(BACKGROUND_IMAGE, (0, 0))

    # 绘制精灵组
    bird_group.draw(SCREEN)
    pipe_group.draw(SCREEN)
    ground_group.draw(SCREEN)

    # 显示分数
    pygame.display.set_caption("Flappy Bird - Score: {}".format(pygame.time.get_ticks() // 1000))

    # 刷新屏幕
    pygame.display.flip()

    # 设置帧率
    CLOCK.tick(FPS)

这个代码实现了一个基本的愤怒的小鸟游戏，其中包括了鸟、管道、地面等基本元素的定义和更新，以及游戏主循环、事件处理、精灵组的创建和更新等功能。
