用py写一段笨鸟先飞游戏

好的，下面是用Python实现一个简单的笨鸟先飞游戏的代码：

import pygame
import random

# 初始化
pygame.init()

# 设置屏幕大小
screen_width = 288
screen_height = 512
screen = pygame.display.set_mode((screen_width, screen_height))

# 设置标题和图标
pygame.display.set_caption("Flappy Bird")
icon = pygame.image.load("icon.png")
pygame.display.set_icon(icon)

# 加载背景图片和音效
background = pygame.image.load("background.png")
bird_upflap = pygame.image.load("bird_upflap.png")
bird_midflap = pygame.image.load("bird_midflap.png")
bird_downflap = pygame.image.load("bird_downflap.png")
pipe_up = pygame.image.load("pipe_up.png")
pipe_down = pygame.image.load("pipe_down.png")
hit_sound = pygame.mixer.Sound("hit.wav")
wing_sound = pygame.mixer.Sound("wing.wav")
score_sound = pygame.mixer.Sound("point.wav")

# 设置字体
font = pygame.font.Font("04B_19.ttf", 40)

# 定义函数：绘制分数
def draw_score(score):
    score_text = font.render(str(score), True, (255, 255, 255))
    screen.blit(score_text, (screen_width//2 - score_text.get_width()//2, 50))

# 定义类：鸟
class Bird:
    def __init__(self):
        self.x = 50
        self.y = screen_height//2
        self.image = bird_midflap
        self.velocity = 0
        self.gravity = 1
        self.lift = -10
        self.score = 0
        self.is_dead = False

    def flap(self):
        if not self.is_dead:
            wing_sound.play()
            self.velocity += self.lift

    def update(self):
        if not self.is_dead:
            self.velocity += self.gravity
            self.y += self.velocity

            if self.velocity > 10:
                self.velocity = 10

            if self.y < 0:
                self.y = 0
                self.velocity = 0

            if self.y > screen_height - 50:
                self.y = screen_height - 50
                self.velocity = 0

            if self.velocity < 0:
                self.image = bird_upflap
            elif self.velocity > 0:
                self.image = bird_downflap
            else:
                self.image = bird_midflap

    def draw(self):
        screen.blit(self.image, (self.x, self.y))

# 定义类：管道
class Pipe:
    def __init__(self):
        self.x = screen_width + 50
        self.y = random.randint(100, screen_height - 250)
        self.width = 52
        self.height = 320
        self.speed = 4
        self.is_passed = False

    def update(self):
        self.x -= self.speed

    def draw(self):
        screen.blit(pipe_up, (self.x, self.y - self.height))
        screen.blit(pipe_down, (self.x, self.y + 100))

    def is_collided(self, bird):
        if bird.x + 34 > self.x and bird.x < self.x + self.width:
            if bird.y < self.y - self.height + 25 or bird.y + 24 > self.y + 75:
                return True
        return False

# 创建对象
bird = Bird()
pipes = [Pipe()]

# 游戏主循环
running = True
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE:
                bird.flap()

    # 绘制背景
    screen.blit(background, (0, 0))

    # 更新鸟的位置和状态
    bird.update()

    # 绘制鸟
    bird.draw()

    # 更新管道的位置
    for pipe in pipes:
        pipe.update()

        # 检测碰撞
        if pipe.is_collided(bird):
            hit_sound.play()
            bird.is_dead = True

        # 绘制管道
        pipe.draw()

        # 计分
        if not pipe.is_passed and pipe.x < bird.x:
            pipe.is_passed = True
            bird.score += 1
            score_sound.play()

        # 添加新管道
        if pipe.x < -pipe.width:
            pipes.append(Pipe())

        # 删除离开屏幕的管道
        if pipes[0].x < -pipes[0].width:
            pipes.pop(0)

    # 绘制分数
    draw_score(bird.score)

    # 刷新屏幕
    pygame.display.update()

# 退出游戏
pygame.quit()

需要注意的几点：

- 游戏中使用了一些图片和音效，需要提前准备好。
- 游戏中的鸟和管道都是由类来表示的，方便管理和操作。
- 游戏中的管道是动态生成的，随着时间的推移不断向左移动，同时也不断生成新的管道，从而实现无限循环。
