[PyGame] Snake game: how to get an instance for my snake's body multiple times?

[hajebazil]

i am totaly begginer in programming and i am learning all by myself,sooo ty in andvance for any help. i am trying to make a snake game using pygame.My problem is that when the game starts i have the whole body of the snake and when the snake starts to move it desappears and i have only the head and the 1st block of the body. i know that i dont need all this complex code for such a simple game, but i want to upgrade it as much as i can adding more and more things so i can train myself to learn better a higher lvl of logic for my future projects. in my new game def i use my BODY_LIST to create my instace multiple times but when i am doint the same thing in the class it doesn't work...

In the main.py def new() i have this " for pos in BODY_LIST: self.body = Body(self,pos[0],pos[1]) " and it gives me the whole snake at the beggining.Then in sprites.py in Head class and Body class i have this print(self.pos_list) checkers and it seems that both work fine and i am getting both list printed as i want. Soooo...why in Body class movement() works fine but only for the first block of the body(that means the lost indexof my list)


this is my main:

from sprites import *
from config import *
import sys

class Game:

    def __init__(self):
        pygame.init()

        self.running = True
        self.screen = pygame.display.set_mode((WIN_WIDTH, WIN_HEIGHT))
        self.clock = pygame.time.Clock()

    def new(self):
        self.playing = True
        self.all_sprites = pygame.sprite.LayeredUpdates()
        self.blocks = pygame.sprite.LayeredUpdates()
        self.target = pygame.sprite.LayeredUpdates()
        self.ground = pygame.sprite.LayeredUpdates()
        self.head = Head(self,32,24,)
        for pos in BODY_LIST:
         self.body = Body(self,pos[0],pos[1])

    def events(self):
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                self.playing = False
                self.running = False

    def update(self):
        self.all_sprites.update()

    def draw(self):
        self.screen.fill(BLACK)
        self.all_sprites.draw(self.screen)
        self.clock.tick(PLAYER_SPEED)
        pygame.display.update()

    def main(self):
        while self.playing:

            self.events()
            self.update()
            self.draw()
        self.running = False
    def game_over(self):
        pass
    def intro(self):
        pass

g = Game()
#g.intro()
g.new()
while g.running:
    g.main()
    #g.game_over()
pygame.quit()
sys.exit()

this my sprites.py :

from config import *
import math
import random

class Head(pygame.sprite.Sprite):
    def __init__(self,game, x, y):
        self.game = game
        self.groups = self.game.all_sprites
        pygame.sprite.Sprite.__init__(self,self.groups)
        self.clock = pygame.time.Clock()
        # Head
        self.x = x * TILESIZE
        self.y = y * TILESIZE
        self.width = TILESIZE
        self.height = TILESIZE
        self.move= [0,0]
        self.pos_list= POS_LIST

        self.image = pygame.Surface([self.width, self.height])
        self.image.fill(RED)
        self.rect = self.image.get_rect()
        self.rect.x = self.x
        self.rect.y = self.y

    def update(self):
        self.movement()
        self.rect = self.rect.move(self.move)
        if self.game.head.move != [0, 0]:
         self.pos_list.append([int(self.rect.x/10), int(self.rect.y/10)])
         if len(self.pos_list) > SNAKE_SIZE :
          self.pos_list.pop(0)

         print(self.pos_list)

    def movement(self):
        keys = pygame.key.get_pressed()
        if keys[pygame.K_LEFT] and self.move != (TILESIZE, 0) :
            self.move = (-TILESIZE, 0)
        if keys[pygame.K_RIGHT] and self.move != (-TILESIZE, 0):
            self.move = (TILESIZE, 0)
        if keys[pygame.K_UP] and self.move != (0, TILESIZE):
            self.move = (0, -TILESIZE)
        if keys[pygame.K_DOWN] and self.move != (0, -TILESIZE):
            self.move = (0, TILESIZE)

class Body(pygame.sprite.Sprite):
    def __init__(self,game,x,y):
        self.game = game
        self.groups = self.game.all_sprites
        pygame.sprite.Sprite.__init__(self,self.groups)

        self.pos_list =POS_LIST[1:-1]
        self.x = x * TILESIZE
        self.y = y * TILESIZE
        self.width = TILESIZE
        self.height = TILESIZE
        self.move = [0, 0]

        self.image = pygame.Surface([self.width, self.height])
        self.image.fill(GREEN)
        self.rect = self.image.get_rect()
        self.rect.x = self.x
        self.rect.y = self.y

    def update(self):

        self.pos_list=POS_LIST[1:-1]
        self.movement()

    def movement(self):
      if self.game.head.move != [0, 0]:
             for pos in self.pos_list:
              self.rect = pos[0]*10,pos[1]*10
             print(self.pos_list)

and this is my config:

WIN_HEIGHT = 480
TILESIZE = 10

BLACK = (0,0,0)
GREEN=(0,255,0)
