使用Python来下一场雪
具体效果:(大雪缓缓下落)
完整代码:
import pygame
import random
# 初始化 Pygame
pygame.init()
# 设置窗口
width, height = 800, 600
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("下雪动画")
# 定义雪花类
class Snowflake:
def __init__(self):
self.x = random.randint(0, width)
self.y = random.randint(0, height)
self.size = random.randint(2, 5)
self.speed = random.uniform(1, 3)
def fall(self):
self.y += self.speed
if self.y > height:
self.y = 0
self.x = random.randint(0, width)
def draw(self):
pygame.draw.circle(screen, (255, 255, 255), (self.x, self.y), self.size)
# 创建雪花列表
snowflakes = [Snowflake() for _ in range(100)]
# 主循环
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
screen.fill((0, 0, 0)) # 填充背景
for snowflake in snowflakes:
snowflake.fall()
snowflake.draw()
pygame.display.flip()
pygame.time.delay(30)
pygame.quit()
