python飘落樱花

使用Python编程语言可以实现樱花飘落的效果。通过使用Pygame库和一些简单的代码，我们可以在屏幕上呈现出美丽的樱花景象。下面是一个实现樱花飘落效果的示例代码：

import pygame
from pygame.locals import *
import random

# 定义樱花类
class CherryBlossom:
    def __init__(self):
        self.x = random.randint(0, SCREEN_WIDTH)
        self.y = random.randint(-SCREEN_HEIGHT, 0)
        self.speed = random.randint(MIN_SPEED, MAX_SPEED)
        self.size = random.randint(MIN_SIZE, MAX_SIZE)

    def update(self):
        self.y += self.speed
        if self.y > SCREEN_HEIGHT:
            self.y = random.randint(-SCREEN_HEIGHT, 0)
            self.x = random.randint(0, SCREEN_WIDTH)
            self.speed = random.randint(MIN_SPEED, MAX_SPEED)
            self.size = random.randint(MIN_SIZE, MAX_SIZE)

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

# 初始化Pygame
pygame.init()

# 设置屏幕尺寸和帧率
SCREEN_WIDTH, SCREEN_HEIGHT = 800, 600
screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
pygame.display.set_caption("Cherry Blossom Falling")
clock = pygame.time.Clock()

# 定义常量
CHERRY_BLOSSOMS_COUNT = 100  # 樱花数量
MIN_SPEED, MAX_SPEED = 1, 3  # 樱花下落速度范围
MIN_SIZE, MAX_SIZE = 5, 10  # 樱花大小范围
WHITE = (255, 255, 255)

# 创建樱花对象并绘制它们
cherry_blossoms = []
for _ in range(CHERRY_BLOSSOMS_COUNT):
    cherry_blossoms.append(CherryBlossom())

# 渲染循环
running = True
while running:
    for event in pygame.event.get():
        if event.type == QUIT:
            running = False

    screen.fill((0, 0, 0))  # 清空屏幕

    for cherry_blossom in cherry_blossoms:
        cherry_blossom.update()
        cherry_blossom.draw()

    pygame.display.update()
    clock.tick(60)

pygame.quit()
