Why is only one specific image registering and not others in pygame?

Question

I am new to coding games using pygame so I thought of making a cookie clicker type of game for my first project. My problem is that I can press the cookie and it gives me cookies when pressed but I cannot press the BUY picture that I have on screen. It's like it doesn't register the click. Please help me I have searched for 2 hours I can'ẗ find a solution anywhere. Here's my code:

# import the pygame module
import pygame
pygame.init()


# Define a function for what will happen if the player buys an item (not done)
def shop():
    if buy_image.get_rect().collidepoint(pos):
        times_clicked -= 15

# Start with no clicks
times_clicked = 0


background_colour = ("white")

screen = pygame.display.set_mode((0,0), pygame.FULLSCREEN)
  

pygame.display.set_caption("Cookies")
  

screen.fill(background_colour)



# create a font object.
# 1st parameter is the font file
# which is present in pygame.
# 2nd parameter is size of the font
font = pygame.font.SysFont("arial",32, True)


fullscreen = False


# Variable to keep our game loop running
running = True

clock = pygame.time.Clock()
# game loop
while running:
    
    # Amount of cookies here
    text = font.render(f"Cookies: {times_clicked}", True, "orange")
    
    

    # create a rectangular object for the
    # text surface object
    textRect = text.get_rect()
    
   

    # set the center of the rectangular object.
    textRect.center = (880, 100)
    


    
    # Shop pic
    shop_text = pygame.image.load("shop.png")
    shop_text = pygame.transform.scale(shop_text, (400, 100))

    # Cursor (shop)
    cursor_image = pygame.image.load("cursor.png")
    cursor_image = pygame.transform.scale(cursor_image, (100, 100))

    # Cookie pic
    image = pygame.image.load("cookie.jpeg")
    image = pygame.transform.scale(image, (800, 800))

    # "BUY" pic that doesn't work
    buy_image = pygame.image.load("buy.jpeg")
    buy_image = pygame.transform.scale(buy_image, (100, 80))


    for event in pygame.event.get():
        screen.fill(background_colour)
        screen.blit(image, (100, 60))
        screen.blit(text, textRect)
        screen.blit(shop_text, (1250, 20))
        screen.blit(cursor_image, (1550, 120))
        screen.blit(buy_image, (1400, 130))
        
        
        if event.type == pygame.MOUSEBUTTONDOWN:

            # Set the pos postions of the mouse click
            pos = pygame.mouse.get_pos()

            # Check if cookie picture is pressed
            if image.get_rect().collidepoint(pos):
                
                times_clicked += 1
            
            # Check if BUY picture is pressed
            shop()
            
        
        
                

        # Check for QUIT event      
        if event.type == pygame.QUIT:
            running = False
    # Update the display using flip
    pygame.display.flip()
    clock.tick(60)

Answer 1

image.get_rect() gives Rect() but only with size of image - it always gives (0,0) as its position.

You should get it only once (before loop) and assign to variable ie. image_rect and assign position to this object

image_rect = image.get_rect()
image_rect.x = 100
image_rect.y = 60

And later use it to check collision

if image_rect.collidepoint(event.pos):

And you can use it also to display image.

blit(image, image_rect)

EDIT:

I didn't run it because I don't have images but it could be something like this:

import pygame

# --- classes ---

# empty

# --- functions ---

def shop(pos, times_clicked):
    if buy_image_rect.collidepoint(pos):
        times_clicked -= 15
    return times_clicked

# --- main ---

times_clicked = 0

background_colour = "white"

fullscreen = False

# - start -

pygame.init()

screen = pygame.display.set_mode((0,0), pygame.FULLSCREEN)
pygame.display.set_caption("Cookies")

# - objects -

shop_text = pygame.image.load("shop.png")
shop_text = pygame.transform.scale(shop_text, (400, 100))
shop_text_rect = shop_text.get_rect()
shop_text_rect.x = 1250
shop_text_rect.y = 20

cursor_image = pygame.image.load("cursor.png")
cursor_image = pygame.transform.scale(cursor_image, (100, 100))
cursor_image_rect = cursor_image.get_rect()
cursor_image_rect.x = 1550
cursor_image_rect.y = 120

image = pygame.image.load("cookie.jpeg")
image = pygame.transform.scale(image, (800, 800))
image_rect = image.get_rect()
image_rect.x = 100
image_rect.y = 60

buy_image = pygame.image.load("buy.jpeg")
buy_image = pygame.transform.scale(buy_image, (100, 80))
buy_image_rect = buy_image.get_rect()
buy_image_rect.x = 1400
buy_image_rect.y = 130

font = pygame.font.SysFont("arial", 32, True)

# - loop -

running = True

clock = pygame.time.Clock()

while running:
    
    # - events -
    
    for event in pygame.event.get():
        if event.type == pygame.MOUSEBUTTONDOWN:

            if image_rect.collidepoint(event.pos):
                times_clicked += 1

            times_clicked = shop(event.pos, times_clicked)

        if event.type == pygame.QUIT:
            running = False

    # - calculations -

    text = font.render(f"Cookies: {times_clicked}", True, "orange")
    #text_rect = text.get_rect()
    #text_rect.center = (880, 100)
    text_rect = text.get_rect(center=(880, 100))

    # - draws -
    
    screen.fill(background_colour)
    
    screen.blit(image, image_rect)
    screen.blit(text, text_rect)
    screen.blit(shop_text, shop_text_rect)
    screen.blit(cursor_image, cursor_image_rect)
    screen.blit(buy_image, buy_image_rect)

    # - update -

    pygame.display.flip()
    clock.tick(60)
