Managing Groups in pygame

Question

I am creating a game where when you kill one mob, two more appears. I have it so when you kill one mob, the two others appear, but only one stays visible and behaves like it

Answer 1

1. Your code is erasing the Rect's width and height. If you want to use coordinates of the center, use:

   self.rect = self.image.get_rect()
   self.rect.center = location
   

2. What is mobs.add() in update()? Because update is normally called every frame, and I'm guessing mobs is a sprite group.

3. Your update:

   for Mob in mobs: Mob.moveV() Mob.moveH() screen.blit(Mob.image, Mob.rect)

should be

mobs.update()
mobs.draw(screen)
