I’m trying to create a hierarchy of Pygame Sprite Groups. During the time that the program runs, more sprites will be added to the sub-groups. I am wondering if I have to also add these new sprites to the parent groups manually, or if they will be automatically added to the parent groups simply because they are in the child groups. In short, when you add a sprite group to another sprite group, will the contents of the parent group be updated when you add sprites to the child group?
I’m trying to create several sprite groups, and use pygame to nest the groups:
import pygame
CREATE_NEW_DOG_SPRITE = pygame.USEREVENT + 1
class Dog(pygame.sprite.Sprite):
pass
class Cat(pygame.sprite.Sprite):
pass
class Goldfish(pygame.sprite.Sprite):
pass
animals = pygame.sprite.Group()
mammals = pygame.sprite.Group()
fish = pygame.sprite.Group()
dogs = pygame.sprite.Group()
cats = pygame.sprite.Group()
goldfish = pygame.sprite.Group()
mammals.add([dogs, cats])
fish.add(goldfish)
animals.add([mammals, fish])
pygame.time.set_timer(CREATE_NEW_DOG_SPRITE, 5000)
while True:
for event in pygame.event.get():
if event.type == CREATE_NEW_DOG_SPRITE:
new_dog = Dog()
dogs.add(new_dog)
When new_dog
is added to dogs, will it automatically be added to mammals
and then to animals
?
