Attribute and Other Errors Found in My Python Code

Question

I working with Python right now to build a space invaders project. The errors I'm currently facing is AttributeError: (ai_setting.screen_width, ai_setting.screen_height)) 'Settings' object has no attribute 'screen_width' in Python. There's also an error around the "run_game()" part at the bottom. The game is so far supposed to draw a screen and place a ship image at the bottom center of the screen. Thanks!

import pygame 
from settings import Settings 
from ship import Ship 
import game_functions as gf
def run_game():
 pygame.init()
 ai_setting = Settings()
 #Creating the screen
 screen = pygame.display.set_mode(
 (ai_setting.screen_width, ai_setting.screen_height))
 #Creating title
 pygame.display.set_caption("Space Invasion")
 ship = Ship(screen)
 #Creating the logo/icon
 icon = pygame.image.load("space-invaders.png")
 pygame.display.set_icon(icon)
 while True:
 gf.check_events()
 gf.update(ai_setting, screen,ship)
run_game()

Above: main.py file

class Settings():
 def _init__(self):
 self.screen_width = 800
 self.screen_height = 600
 self.bg_color = (0,255,0)

Above: settings.py file

import pygame
import sys
def check_events():
 for event in pygame.event.get():
 if event.type == pygame.QUIT:
 sys.exit()
def update(ai_settings, screen, ship):
 screen.fill(ai_setting.bg_color)
 ship.blitme
 pygame.display.flip()

Above: game_events.py file

import pygame
class Ship():
 def __init__(self, screen):
 self.screen = screen
 self.image = pygame.image.load("space-invaders.py")
 self.rect = self.image.get_rect()
 self.screen_rect = screen.get_rect()
 self.rect.centerx = self.screen_rect.centerx
 self.rect.bottom = self.screen_rect.bottom
 def blitme(self):
 self.screen.blit(self.image, self.rect)

Above: ship.py file

Answer 1

You have a typo in the Settings class. You're missing an underscore in its __init__. You have:

def _init__(self):

when instead you should have:

def __init__(self):

Because of this typo, the screen_width and screen_height properties will not be created or set when Settings() is called.

• code: Okay I fixed the typo. Now theres a name error of "screen.fill(ai_setting.bg_color) NameError: name 'ai_setting' is not defined" and "run_game gf.update(ai_setting, screen, ship)"
• Random Davis: @code Another typo. You passed it into the update function with the name ai_settings, but you're referring to it as ai_setting within that function. Either change ai_setting to ai_settings in update, or change the ai_settings parameter to ai_setting.
