大家好!今天给你们带来了python pygame下雪效果。
安装pygame:
pip install pygame
完整代码:
importpygame
importrandom
# 初始化pygame
pygame.init()
# 获取屏幕尺寸
screen = pygame.display.set_mode((0, 0), pygame.FULLSCREEN)
pygame.display.set_caption("SnowAnimation")
# 设置背景颜色为黑色
background_color = (0, 0, 0)
# 雪花列表
snow_list = []
# 初始化雪花:[x坐标, y坐标, x轴速度, y轴速度]
fori in range(200):
x = random.randrange(0, screen.get_width())
y = random.randrange(0, screen.get_height())
sx = random.randint(-1, 1)
sy = random.randint(3, 6)
snow_list.append([x,y, sx, sy])
clock = pygame.time.Clock()
# 游戏主循环
done = False
whilenot done:
# 消息事件循环,判断退出
forevent in pygame.event.get():
ifevent.type == pygame.QUIT:
done = True
elifevent.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE:
done = True
# 显示背景颜色
screen.fill(background_color)
# 雪花列表循环
fori in range(len(snow_list)):
# 绘制雪花,颜色、位置、大小
pygame.draw.circle(screen,(255, 255, 255), snow_list[i][:2], snow_list[i][3]-3)
# 移动雪花位置(下一次循环起效)
snow_list[i][0]+= snow_list[i][2]
snow_list[i][1]+= snow_list[i][3]
# 如果雪花落出屏幕,重设位置
ifsnow_list[i][1] > screen.get_height():
snow_list[i][1] = random.randrange(-50, -10)
snow_list[i][0] = random.randrange(0, screen.get_width())
# 刷新屏幕
pygame.display.flip()
clock.tick(20)
# 退出
pygame.quit()
