pygame：将精灵类绘制到屏幕时的错误

Question

我正在尝试使用类player将精灵绘制到屏幕上，但是我得到了追溯。当我将对象绘制到屏幕上时，似乎在抱怨，我不确定是什么原因引起的。我是Pygame的新手，所以我认为我使用的是错误的，或者我缺少的东西我不太了解。

这是我的代码：

import pygame
from sys import exit

# initilaization
pygame.init()
screen = pygame.display.set_mode((800, 600))
pygame.display.set_caption('Bullet hell')

class Player(pygame.sprite.Sprite):
    '''The Main player class'''
    def __init__(self):
        super().__init__()
        self.player_image = pygame.image.load('sprites/player/player.png').convert_alpha()
        self.player_rect = self.player_image.get_rect(topleft = (0, 0))

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

# main game loop
while True:

    # event loop
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()

    player.draw(screen)
    pygame.display.update()

它产生此错误：

Traceback (most recent call last):
  File "/home/linkio/Projects/bullet-hell-game/main.py", line 29, in <module>
    player.draw(screen)
  File "/home/linkio/.local/lib/python3.10/site-packages/pygame/sprite.py", line 552, in draw
    zip(sprites, surface.blits((spr.image, spr.rect) for spr in sprites))
  File "/home/linkio/.local/lib/python3.10/site-packages/pygame/sprite.py", line 552, in <genexpr>
    zip(sprites, surface.blits((spr.image, spr.rect) for spr in sprites))
AttributeError: 'Player' object has no attribute 'image'

我需要更改我的类属性名称。精灵类似乎是根据特定关键字作为属性来工作的。

class Player(pygame.sprite.Sprite):
    '''The Main player class'''
    def __init__(self):
        super().__init__()
        self.image = pygame.image.load('sprites/player/player.png').convert_alpha()
        self.rect = self.image.get_rect(topleft = (0, 0))
