AttributeError：'pygame.Surface'對象沒有屬性'rect'

Question

我不斷收到此錯誤。這是完整的追溯。

Traceback (most recent call last): 
File "C:/Users/Luc/PycharmProjects/game_practice/game.py", line 23, in 
<module> 
run_game() 
File "C:/Users/Luc/PycharmProjects/game_practice/game.py", line 13, in 
run_game 
player = Player(ai_settings, screen) 
File "C:\Users\Luc\PycharmProjects\game_practice\player.py", line 8, in 
__init__ 
self.rect.centerx = screen.rect.left 
AttributeError: 'pygame.Surface' object has no attribute 'rect' 

下面是這是使用的問題「玩家」文件中的代碼：

class Player: 
    def __init__(self, ai_settings, screen): 
     self.screen = screen 
     self.screen_rect = screen.get_rect() 
     self.rect = pygame.Rect((0, 0), (ai_settings.player_width, 
     ai_settings.player_height)) 
     self.rect.centerx = screen.rect.left 
     self.rect.centery = screen.rect.ai_settings.screen_height/2 
     self.color = ai_settings.player_color 

    def draw_player(self): 
     pygame.draw.rect(self.screen, self.color, self.rect) 

當我評論這兩條線：

self.rect.centerx = screen.rect.left 
self.rect.centery = screen.rect.ai_settings.screen_height/2 

該程序將在初始化的矩形運行（0,0）就像它應該的那樣，所以我不確定爲什麼當我包含其他行時該對象有一個屬性錯誤。

的screen是沒有rect屬性pygame.Surface，但你可以通過調用screen.get_rect()你在這一行已經做得到與表面大小的矩形：

self.screen_rect = screen.get_rect() 

現在你只必須使用您的self.screen_rect而不是screen.rect，並且您的代碼應該可以正常工作。

# To place the player at the midleft. 
self.rect.midleft = self.screen_rect.midleft
