闪烁的夜空

代码

import pygame
import random

# 初始化 Pygame
pygame.init()

# 设置屏幕尺寸
WIDTH, HEIGHT = 800, 600
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("星空闪烁")

# 定义星星类
class Star:
    def __init__(self):
        # 随机生成星星的位置
        self.x = random.randint(0, WIDTH)
        self.y = random.randint(0, HEIGHT)
        # 随机生成星星的初始亮度
        self.brightness = random.randint(50, 200)
        # 随机生成星星的闪烁速度
        self.speed = random.uniform(1, 3)

    def update(self):
        # 更新星星的亮度
        self.brightness += self.speed
        # 如果亮度超出范围，改变闪烁方向
        if self.brightness > 255 or self.brightness < 50:
            self.speed = -self.speed

    def draw(self):
        # 将亮度值限制在 0 到 255 之间
        brightness = int(max(0, min(255, self.brightness)))
        # 绘制星星
        pygame.draw.circle(screen, (brightness, brightness, brightness), (int(self.x), int(self.y)), 1)

# 创建星星列表
stars = [Star() for _ in range(200)]

# 主循环
running = True
clock = pygame.time.Clock()

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # 填充背景为黑色
    screen.fill((0, 0, 0))

    # 更新并绘制所有星星
    for star in stars:
        star.update()
        star.draw()

    # 更新显示
    pygame.display.flip()

    # 控制帧率
    clock.tick(120)

# 退出 Pygame
pygame.quit()
