AttributeError：“ pygame.Surface”对象没有属性“ centerx”

如何解决AttributeError：“ pygame.Surface”对象没有属性“ centerx”

我正在读一本有关Python的书，Python速成课程，它在项目中使用了此代码。

import pygame

class Ship:
    def __init__(self,screen):
        self.screen = screen

        # load ship and get its rect
        self.image = pygame.image.load('images/ship.bmp')
        self.rect = self.image.get_rect()
        self.screen_rect = screen.get_rect()

        # start each new ship at the bottom center of the screen
        self.rect.centerx = self.screen.centerx
        self.rect.bottom = self.screen.bottom

    def blitme(self):
        # draw the ship at its current location
        self.screen.blit(self.image,self.rect)

但是显示此错误

AttributeError: 'pygame.Surface' object has no attribute 'centerx'

解决方法

self.screen是与屏幕关联的pygame.Surface对象。您必须获得一个pygame.Rect对象，其表面尺寸为get_rect()：

screen_rect = self.screen.get_rect()
self.rect.centerx = screen_rect.centerx
self.rect.bottom = screen_rect.bottom
