why does the button not draw?-CodePudding

I do not understand why the button does not draw on the background it worked before this does not show an error. here is the code------> is this code wrong ? is my problem even reproducible? it could be in the code for the button i would appreciate the help

import pygame
pygame.init()
screen = pygame.display.set_mode((3840,2160))
running = True
mouse = pygame.mouse.get_pos()

pygame.display.set_caption("GermanBall")
bg = pygame.image.load(r"C:\Users\tomarj\OneDrive - Tata Advanced Systems Limited\Desktop\War Crime\Tan.jpg")
icon = pygame.image.load(r"C:\Users\tomarj\OneDrive - Tata Advanced Systems Limited\Desktop\War Crime\box.png")
button1 = pygame.image.load(r"C:\Users\tomarj\OneDrive - Tata Advanced Systems Limited\Desktop\War Crime\shirt.png").convert_alpha()
class Button():
        def __init__(self,x,y,image, scale):
            width = image.get_width()
            height = image.get_height()
            self.image = pygame.transform.scale(image, (int(width * scale), int(height * scale)))
            self.rect = self.image.get_rect()
            self.rect.topleft = (x,y)
            posmoose = pygame.mouse.get_pos()
            if self.rect.collidepoint(posmoose):
                if pygame.mouse.get_pressed()[0] == 1:
                    print("click")
        def draw(self):
            screen.blit(self.image,(self.rect.x,self.rect.y))
stat = Button(1550,700,button1,0.5) 




pygame.display.set_icon(icon)

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
screen.blit(bg,(0,0))
stat.draw()
pygame.display.update()

The indentation is wrong in your class: methods draw, intro, ... should be at the same level as __init__. But basically your class is useless since you're not creating any object of the class. You should have something like my_button = Button(...) in your code (and outside the class itself).

Also it is good practice to move your class at the top level.

So perhaps you should start from something like that:

import pygame
pygame.init()
screen = pygame.display.set_mode((3840,2160))
running = True
mouse = pygame.mouse.get_pos()

pygame.display.set_caption("GermanBall")
bg = pygame.image.load(r"C:\Users\tomarj\OneDrive - Tata Advanced Systems Limited\Desktop\War Crime\Tan.jpg")
icon = pygame.image.load(r"C:\Users\tomarj\OneDrive - Tata Advanced Systems Limited\Desktop\War Crime\box.png")
button1 = pygame.image.load(r"C:\Users\tomarj\OneDrive - Tata Advanced Systems Limited\Desktop\War Crime\shirt.png").convert_alpha()

pygame.display.set_icon(icon)

class Button():
    def __init__(self,x,y,image, scale):
        ...
    def draw(self):
        ...
    def intro(self):
        ...
    def game(self):
        ...
    def manager():
        ...

my_button = Button(100, 200, button1, 1.0)  # <- create a button
while running == True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    screen.blit(bg,(0,0))
    my_button.draw()  # <- draw the button
    pygame.display.update()

Your draw function doesn't know what screen is. You should add an argument screen to your draw function, and pass the function call in the main loop the screen.
