Python繁星宇宙

以下是使用Python绘制繁星宇宙的代码和步骤：

1. 导入必要的库

import pygame
import random

2. 初始化pygame

pygame.init()

3. 设置画布大小和标题

width, height = 800, 600
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("Starry Sky")

4. 定义星星类

class Star:
    def __init__(self, x, y, size, color):
        self.x = x
        self.y = y
        self.size = size
        self.color = color

    def draw(self, screen):
        pygame.draw.circle(screen, self.color, (self.x, self.y), self.size)

5. 定义生成随机星星的函数

def create_star():
    x = random.randint(0, width)
    y = random.randint(0, height)
    size = random.randint(1, 3)
    color = (255, 255, 255)
    return Star(x, y, size, color)

6. 生成一定数量的星星

stars = []
for i in range(100):
    stars.append(create_star())

7. 游戏主循环

while True:
    # 处理退出事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

    # 绘制背景
    screen.fill((0, 0, 0))

    # 绘制星星
    for star in stars:
        star.draw(screen)

    # 更新屏幕
    pygame.display.update()
