Pygame Scrolling Bug With Enemys

Question

I have a problem with my enemy where when my player scrolls left the enemy scrolls with the player. Is there anyway to fix this?

My full code is linked below, as it's too long to fit here.

What I was trying to do is make my enemy not to change its position when my window is scrolling. Its doing the same for right and left and keeps following the player.

while runninggame:
    clock.tick(FPS)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            runninggame = False
  [...]
# I did the same for my players key movement  this part suppose to not make my player scroll
if playerman.y < 250:
        playerman.y += 1
        for platform in platforms:
            platform.y += playerman.speed
        for enemys in enemying:
            enemys.y += playerman.speed

My enemy class:

class enemy:
    def __init__(self,x,y,height,width,end):
        self.x = x
        self.y =y
        self.esright = [pygame.image.load("esright1.png"),
        pygame.image.load("esright1.png"),
        pygame.image.load("esright2.png"),
        pygame.image.load("esright3.png"),
        pygame.image.load("esright4.png"),
        pygame.image.load("esright5.png"),
        pygame.image.load("esright6.png"),
        pygame.image.load("esright7.png"),
        pygame.image.load("esright8.png"),
        pygame.image.load("esright9.png"),
        pygame.image.load("esright10.png"),
        pygame.image.load("esright11.png"),
        pygame.image.load("esright12.png"),
        pygame.image.load("esright13.png"),
        pygame.image.load("esright14.png"),
        pygame.image.load("esright15.png"),
        pygame.image.load("esright16.png"),
        pygame.image.load("esright17.png"),
                          ]
        self.esleft = [pygame.image.load("esleft1.png"),
        pygame.image.load("esleft1.png"),
        pygame.image.load("esleft2.png"),
        pygame.image.load("esleft3.png"),
        pygame.image.load("esleft4.png"),
        pygame.image.load("esleft5.png"),
        pygame.image.load("esleft6.png"),
        pygame.image.load("esleft7.png"),
        pygame.image.load("esleft8.png"),
        pygame.image.load("esleft9.png"),
        pygame.image.load("esleft10.png"),
        pygame.image.load("esleft11.png"),
        pygame.image.load("esleft12.png"),
        pygame.image.load("esleft13.png"),
        pygame.image.load("esleft14.png"),
        pygame.image.load("esleft15.png"),
        pygame.image.load("esleft16.png"),
        pygame.image.load("esleft17.png"),
                          ]
        self.esright = [pygame.transform.scale(image,(image.get_width()//3,image.get_height()//3)) for image in self.esright]
        self.esleft = [pygame.transform.scale(image,(image.get_width()//3,image.get_height()//3)) for image in self.esleft]
        self.height = height
        self.width = width
        self.anim_index = 0
        self.distance = 80
        self.speed = 8
        self.vel = 3
        self.path = [x,end]
        self.walking_index = 0
        self.rect = pygame.Rect(x,y,height,width)
       def draw(self,window):
       self.move()
       if self.Walking_index + 1 >= 33:
           self.Walking_index = 0
       if self.vel > 0:
           window.blit(self.esright[self.Walking_index//3], (self.x,self.y))
           self.Walking_index += 1
       else:
           window.blit(self.esleft[self.Walking_index//3], (self.x,self.y))
           self.Walking_index += 1
       def move(self):
       if self.vel > 0:
           if self.x + self.vel < self.path[1]:
               self.x += self.vel
           else:
               self.vel = self.vel * -1
               self.Walking_index = 0
       else:
           if self.x - self.vel >  self.path[0]:
               self.x += self.vel
           else:
               self.vel = self.vel * -1
               self.Walking_index = 0

Where I defined the enemy class:

black = (0,0,0)
enemys1 = enemy(550,436,50,50,300)
enemys = [enemys1]

My entire code is here.

The issue is caused by how you draw the enemies. When you draw an object, you are using something like: screen.blit(image, pos) however, when you move, that pos variable does not update to compensate for the moving plane of view. Instead, do something like (this is pseudocode, so it wont work):

def onscroll(enemies_list, delta_scroll): # the delta_scroll variable is the change in 
#the screens location (positive or negative)
    for x in enemies_list:
        x.position = (x.position[0] - delta_scroll, x.position[1])

also, if you have a return position, you want to also compensate using:

x.return_pos -= delta_scroll

Hope this helps!
