粒子光效圣诞树python

很高兴为您解答。下面是一个使用Python和Pygame库绘制粒子光效圣诞树的示例代码：

import pygame
import random

# 初始化Pygame
pygame.init()

# 设置窗口大小和标题
size = (800, 600)
screen = pygame.display.set_mode(size)
pygame.display.set_caption("Particle Christmas Tree")

# 定义颜色
WHITE = (255, 255, 255)
GREEN = (0, 255, 0)
RED = (255, 0, 0)

# 定义粒子类
class Particle(pygame.sprite.Sprite):
    def __init__(self, x, y):
        super().__init__()
        self.image = pygame.Surface([4, 4])
        self.image.fill(WHITE)
        self.rect = self.image.get_rect()
        self.rect.x = x
        self.rect.y = y
        self.change_x = random.randrange(-3, 4)
        self.change_y = random.randrange(-3, 4)
        self.life = 60

    def update(self):
        self.rect.x += self.change_x
        self.rect.y += self.change_y
        self.life -= 1
        if self.life == 0:
            self.kill()

# 定义粒子组
all_sprites_list = pygame.sprite.Group()

# 定义主循环
done = False
clock = pygame.time.Clock()

while not done:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True

    # 绘制圣诞树
    screen.fill(GREEN)
    pygame.draw.rect(screen, BROWN, [375, 500, 50, 100])
    pygame.draw.polygon(screen, GREEN, [[275, 500], [475, 500], [375, 350]])
    pygame.draw.polygon(screen, GREEN, [[250, 450], [500, 450], [375, 300]])
    pygame.draw.polygon(screen, GREEN, [[225, 400], [525, 400], [375, 250]])

    # 生成粒子
    if random.randrange(0, 10) == 0:
        particle = Particle(375, 250)
        all_sprites_list.add(particle)

    # 更新粒子
    all_sprites_list.update()

    # 绘制粒子
    all_sprites_list.draw(screen)

    # 更新屏幕
    pygame.display.flip()
    clock.tick(60)

# 退出Pygame
pygame.quit()
