有人可以告诉我我的代码有什么问题吗？ 我在调试时遇到问题

Question

I am trying to make a game for school project where you just shoot enemies on the other side of the screen. And I am having trouble debugging. I am using python and pygame. The errors come from the image and the player_image, i think that the main problem is something with displaying the background as that is what I was trying to do Here is my code:

import pygame, sys

class Player(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__(image)
        self.image = image
        self.rect = self.image.get_rect(center = (screen_width//2, screen_height//2))


        def update(self):
            self.rect.center = pygame.mouse.get_pos()

        def create_bullet(self):
            return Bullet(pygame.mouse.get_pos()[0].pygame.mouse.get_pos()[1])


class Bullet (pygame.sprite.Sprite):
    def __init__(self,pos_x,pos_y):
        super().def__init__()
        self.image = pygame.Surface((50,10))
        self.image.fill((255,0,0))
        self.rect = self.image.get_rect(center = (pos_x,pos_y))

    def update(self):
        self.rect.x += 5

# general setup
pygame.init()
clock = pygame.time.Clock()


# game screen
screen_width = 1920
screen_height = 1080
screen = pygame .display.set_mode((screen_width, screen_height))
background = pygame.image.load("BackGround.png")

# player
player = pygame.image.load("spriteshd00.png")
player = Player(player_image)
player_group = pygame.sprite.Group()
player_group.add(player)

bullet_group = pygame.sprite.Group()

# caption
pygame.display.set_caption("Wild-West Shooter")



# makes game quit
while True:
        for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    pygame:quit()
                    sys.exit()
                if event.type == pygame.MOUSEBUTTONDOWN:
                    bullet_group.add(player.create_bullet())

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

            # update the game states and positions of objects
            player_group.update()

            # draw the background
            screen.blit(background, (0, 0))

            # draw objects
            player_group.draw(screen)

            # update display
            pygame.display.flip()

            clock.tick(120)


    #drawing
        pygame.display.flip()
        player_group.draw(screen)
        bullet_group.draw(screen)
        player_group.update()
        bullet.group.update()
        screen.blit(background,(0,0))
        clock.tick(120)





if __name__ == "__main__" :
        theApp = App()
        theApp.on_execute()

Answer 1

image must be an argument of the constructor of Player :

class Player(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__(image)
        self.image = image
        
        # [...]

The name of the _Surface is player_image :

player = pygame.image.load("spriteshd00.png")

player_image = pygame.image.load("spriteshd00.png")
player = Player(player_image)

There is another typo in the constructor of Bullets

super().def__init__()

super().__init__()

Furthermore there are some structural and Indentation issues. Complete and working code:

import pygame, sys

class Player(pygame.sprite.Sprite):
    def __init__(self, image):
        super().__init__()
        self.image = image
        self.rect = self.image.get_rect(center = (screen_width//2, screen_height//2))

    def update(self):
        self.rect.center = pygame.mouse.get_pos()

    def create_bullet(self):
        return Bullet(*pygame.mouse.get_pos())

class Bullet (pygame.sprite.Sprite):
    def __init__(self,pos_x,pos_y):
        super().__init__()
        self.image = pygame.Surface((50,10))
        self.image.fill((255,0,0))
        self.rect = self.image.get_rect(center = (pos_x,pos_y))

    def update(self):
        self.rect.x += 5

# general setup
pygame.init()
clock = pygame.time.Clock()

# game screen
screen_width = 1920
screen_height = 1080
screen = pygame .display.set_mode((screen_width, screen_height))
background = pygame.image.load("BackGround.png")

# player
player_image = pygame.image.load("spriteshd00.png")
player = Player(player_image)
player_group = pygame.sprite.Group()
player_group.add(player)

bullet_group = pygame.sprite.Group()

# caption
pygame.display.set_caption("Wild-West Shooter")

# makes game quit
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame:quit()
            sys.exit()
        if event.type == pygame.MOUSEBUTTONDOWN:
            bullet_group.add(player.create_bullet())

    player_group.update()
    bullet_group.update()

    screen.blit(background,(0,0))
    player_group.draw(screen)
    bullet_group.draw(screen)
    pygame.display.flip()
    clock.tick(120)
