使用Python的pygame库实现下雪的效果
关于Python中pygame游戏模块的安装使用可见 https://blog.csdn.net/cnds123/article/details/119514520
先给出效果图：
源码如下：
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))# 设置雪花属性
snowflakes = []
for i in range(50):x = random.randrange(0, width)y = random.randrange(0, height)speed = random.uniform(1, 3)size = random.randint(3, 6) # 雪花大小参数snowflakes.append([x, y, speed, size])# 循环直到用户关闭窗口
running = True
while running:for event in pygame.event.get():if event.type == pygame.QUIT:running = False# 填充屏幕颜色screen.fill((200, 200, 200)) # (0, 0, 0)黑色；(200, 200, 200)阴天# 绘制雪花for flake in snowflakes:pygame.draw.circle(screen, (255, 255, 255), (int(flake[0]), int(flake[1])), flake[3]) # 使用大小参数绘制雪花flake[1] += flake[2] # 移动雪花if flake[1] > height:flake[1] = random.randrange(-50, -10)flake[0] = random.randrange(0, width)# 更新屏幕pygame.display.flip()# 控制帧率pygame.time.Clock().tick(30)# 退出pygame
pygame.quit()
下面给出改进版
效果图：
使用一张背景图片（我这里文件名：snow_background.jpg），和代码文件放在同一目录下
源码如下：
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))# 加载背景图片
background = pygame.image.load('snow_background.jpg')
background = pygame.transform.scale(background, (width, height))# 设置雪花属性
snowflakes = []
for i in range(50):x = random.randrange(0, width)y = random.randrange(0, height)speed = random.uniform(1, 3)size = random.randint(3, 6) # 雪花大小参数snowflakes.append([x, y, speed, size])# 循环直到用户关闭窗口
running = True
while running:for event in pygame.event.get():if event.type == pygame.QUIT:running = False# 填充屏幕颜色#screen.fill((200, 200, 200)) # (0, 0, 0)黑色；(200, 200, 200)阴天# 绘制背景图片screen.blit(background, (0, 0))# 移动雪花并重新绘制for flake in snowflakes:pygame.draw.circle(screen, (255, 255, 255), (int(flake[0]), int(flake[1])), flake[3]) # 使用大小参数绘制雪花flake[1] += flake[2] # 移动雪花if flake[1] > height:flake[1] = random.randrange(-50, -10)flake[0] = random.randrange(0, width)# 更新屏幕pygame.display.flip()# 控制帧率pygame.time.Clock().tick(30)# 退出pygame
pygame.quit()
