我正在创建一个代表变形虫进化的模拟。它们由在画布上移动的红色方块表示。如果它们发生碰撞，它们就会产生后代。进化带有一个称为成熟速度的数量。变形虫只有在达到一定年龄后才能繁殖，而它们年龄增长的速度取决于它们的成熟速度，这会遗传给后代（有一些随机突变的机会）。这是我的代码：

    if p == 1000:
        print(amoebas)
        p = 0

        p = p + 1

    time.sleep(0.00001)
    screen.fill((255, 255, 255))
    
    for event in pygame.event.get():
        if event.type == QUIT:
            break
        
    amoebas.update()
    a = Amoeba(1, 1, 1)
    a.collide()

        

    for entity in all_sprites:
        screen.blit(entity.surf, entity.rect)
        
    pygame.display.flip()
    

pygame.quit()

对不起，它比较长。程序中的一切工作正常，除了后代似乎由于某种原因没有繁殖，这意味着一旦原件死亡，什么都不会发生。

我的问题如此含糊的原因是我真的不明白问题可能是什么 - 原始变形虫的类与后代的类相同，并且程序没有抛出任何错误消息。
