pygame flappy bird clone pipe-spawning

Question

I'm having trouble with spawning in the pipes from flappy bird, I'm trying to use a class for the information (surfaces, drawing rects, movement). However, I can't seem to figure out how to draw rectangles with it.

In my flappy bird clone, I'm using 2 pipes (one coming down from the top, and the other to the bottom). But what I've gathered so far is for drawing rects, you must use self.rect, which seems like it can only hold one value at a time, so I can't exactly access information for both the top and bottom pipes.

import pygame
from sys import exit

class Player(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__() # import files
        bird1 = pygame.image.load('graphics/bird/Bird1.png').convert_alpha()
        bird2 = pygame.image.load('graphics/bird/Bird2.png').convert_alpha()

        self.bird_fly = [bird1, bird2] # sets up animation index
        self.bird_index = 0
        self.gravity = 0

        self.image = self.bird_fly[self.bird_index]
        self.rect = self.image.get_rect(midbottom = (100,300))

    def animation(self):
        self.bird_index += 0.1
        if self.bird_index >= len(self.bird_fly): self.bird_index = 0
        self.image = self.bird_fly[int(self.bird_index)]

    def apply_gravity(self):
        self.rect.y += 5
    
    def input(self):   
        keys = pygame.key.get_pressed()
        if keys[pygame.K_SPACE]:
            self.rect.y -= 15


    def update(self): # gives access
        self.animation()
        self.apply_gravity()
        self.input()

class Pipes(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        top_pipe = pygame.image.load('graphics/pipes/top_green_pipe.png')
        bottom_pipe = pygame.image.load('graphics/pipes/bottom_green_pipe.png')


        pipes_list = [top_pipe, bottom_pipe]
        self.image = pipes_list[]
        
        self.rect = self.image.get_rect(midbottom = (800, y))


pygame.init()
screen = pygame.display.set_mode((800, 400))
clock = pygame.time.Clock()



pygame.display.set_caption('Flabby Pird')

#groups
player = pygame.sprite.GroupSingle()
player.add(Player())

pipes = pygame.sprite.Group()
pipes.add (Pipes())

#environment
sky = pygame.image.load('graphics/sky.png')
ground = pygame.image.load('graphics/ground.png')
fork = pygame.image.load('graphics/fork.png')
fork_rect = fork.get_rect(midbottom = (80, 200))


while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()

    screen.blit(ground, (0, 300))    
    screen.blit(sky, (0,0))
    screen.blit(fork, fork_rect)

    # draws player from "# groups"
    player.draw(screen)
    player.update() 

    screen.blit()

    pygame.display.update()
    clock.tick(60)  # limits FPS to 60

pygame.quit()

here is my current code, im experimenting with drawing an entire list, but im not sure how to change the Y-value of each item in list

You have to create one Sprite form each pipe. There is no other possibilkity. — Rabbid76, Apr 08 '23 at 05:54

A pygame.sprite.Sprite represents one single sprite. Therefore you cannot handle multiple objects with one sprite. Create a pipe class and create 2 pipes. You can group the pipes together:

class Pipe(pygame.sprite.Sprite):
    def __init__(self, is_top, image_name):
        super().__init__()
        self.image = pygame.image.load(image_name)
        if is_top:
            self.rect = self.image.get_rect(midtop = (800, 0))
        else:
            self.rect = self.image.get_rect(midbottom = (800, 0))

top_pipe = top_pipe(True, 'graphics/pipes/top_green_pipe.png')
bottom_pipe = bottom_pipe(False, 'graphics/pipes/bottom_green_pipe.png')
pipes = pygame.sprite.Group([top_pipe, bottom_pipe])
