Question

我一直收到这个错误。这是完整的追溯。

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'

以下是有问题的“播放器”文件的代码：

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)

当我评论这两行时：

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

程序运行的矩形初始化为（0,0），就像它应该的那样，所以当我包含其他行时，我不确定为什么对象有属性错误。

Answer 1

screen是一个没有rect属性的pygame.Surface，但你可以通过调用screen.get_rect()来获取表面大小的矩形：

self.screen_rect = screen.get_rect()

现在您只需使用self.screen_rect代替screen.rect，您的代码就可以了。

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

AttributeError：'pygame.Surface'对象没有属性'rect'
