Part 2: the aliens squad

We make the aliens thanks to this class and the following list

class Alien(pygame.sprite.Sprite):
    def __init__(self, file, x, y):

        super(Alien, self).__init__()
        self.x = x
        self.y = y
        self.image = load("imgs\\" + file)
        self.w, self.h = self.image.get_size()
        self.rect = pygame.Rect(self.x, self.y, self.w, self.h)
        #self.rect.center = self.x, self.y
      
        g.add(self)
        aliens.add(self)

We will create an alien for each item in the list in different rows. We added the aliens in their own group: aliens.

squad = [
    [1,1,1,1,1,1,1,1], # line 1... [item, item]
    [1,1,1,1,1,1,1,1],
    [1,1,1,1,1,1,1,1],
    [1,1,1,1,1,1,1,1]
    ]
    

for y, line in enumerate(squad):
    for x, item in enumerate(line):
        if item == 1:
            alien = Alien("alien1", 70 + 50 * x, 30 + 50 * y)
