在游戏开始之前，通过从Mob类调用它来启动5个对象（僵尸）。然后，存储在名为zombie的列表中。

zombie = [None]*5
def newmob():
    for i in range(5):
        zombie[i] = Mob()
        all_sprites.add(zombie[i])
        mobs.add(zombie[i])

newmob（）在进入游戏循环之前被调用。

newmob()
while running:
    for i in range(len(zombie)):
        hits = pygame.sprite.spritecollide(player,mobs,False,pygame.sprite.collide_mask)
        if hits:
            player.shoot = False
            player.startShoot = True
            zombie[i].damage()
            if zombie[i].health() <= 0:
                zombie[i].dying()
        atks = pygame.sprite.spritecollide(barricade,pygame.sprite.collide_mask)
        if atks:
            zombie[i].attacking()
            barricade.damage()
            print(barricade.health())
            if barricade.health() <= 0:
                barricade.destroyed()
                zombie[i].walking()

暴民类如下：

基本上，我正在尝试创建一堆僵尸，但是生成的僵尸却以某种方式彼此关联，就像当一个人将所有其他死者一起死等时一样……
