python3d爱心粒子代码

以下是一个简单的Python 3D爱心粒子代码，可以在Pygame中实现：

import pygame
import random

pygame.init()

size = (700, 500)
screen = pygame.display.set_mode(size)

pygame.display.set_caption("3D Heart Particle System")

done = False

clock = pygame.time.Clock()

class Particle():
    def __init__(self):
        self.x = 0
        self.y = 0
        self.z = 0
        self.size = 0
        self.color = (0,0,0)

    def move(self):
        self.z -= 1
        if self.z <= 0:
            self.z = 400
            self.x = random.randrange(-200,200)
            self.y = random.randrange(-200,200)
            self.size = random.randrange(10,20)
            self.color = (random.randrange(50,255),random.randrange(50,255),random.randrange(50,255))

def draw_particles(particles):
    for p in particles:
        x = int(p.x * 400 / p.z) + 350
        y = int(p.y * 400 / p.z) + 250
        size = int(p.size * 400 / p.z)
        pygame.draw.circle(screen, p.color, [x,y], size)

particles = []

for i in range(500):
    p = Particle()
    p.x = random.randrange(-200,200)
    p.y = random.randrange(-200,200)
    p.z = random.randrange(1,400)
    p.size = random.randrange(10,20)
    p.color = (random.randrange(50,255),random.randrange(50,255),random.randrange(50,255))
    particles.append(p)

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

    screen.fill((255,255,255))

    draw_particles(particles)

    for p in particles:
        p.move()

    pygame.display.flip()

    clock.tick(60)

pygame.quit()
