self.rect.x = Game.screen.get_rect().centerx ^^^^^^^^^^^^^^^^^^^^ AttributeError: 'int' object has no attribute 'get_rect'

这个错误表示你尝试在一个整数对象上调用 `get_rect()` 方法，但整数对象没有名为 `get_rect()` 的属性。

通常情况下，`get_rect()` 方法是用于获取图像或表面对象的矩形区域的方法。你可能在一个整数值上意外地使用了这个方法。

要解决这个问题，你需要确保你要调用 `get_rect()` 方法的对象是一个有效的图像或表面对象。在这种情况下，你可能在一个整数值上尝试调用 `get_rect()` 方法，应该调用 `get_rect()` 方法的对象是一个具有该方法的表面对象。

请检查你的代码并确保在调用 `get_rect()` 方法之前，你正在操作一个表面对象。如果你仍然遇到问题，请提供更多的代码和上下文，以便我能够更好地帮助你解决问题。

在代码中添加以下代码可以在游戏界面上添加一条分割线：

# 画一条分割线
pygame.draw.line(screen, [0, 0, 0], [0, 240], [640, 240], 5)

将其添加在`screen.fill([255,255,255])`之后，完整代码如下：

让这个代码中的飞船可以移动#大战外星人 import pygame from settings import Settings from ship import Ship import game_functions as gf def run_game(): pygame.init() ai_setting=Settings() screen=pygame.display.set_mode((ai_setting.screen_width,ai_setting.screen_height)) pygame.display.set_caption("alien invasion") ship=Ship(screen,ai_setting) while True: gf.check_event(ship) ship.update(screen) gf.update_screen(ai_setting,screen,ship) pygame.display.flip() run_game() #game_functions import sys import pygame def check_event(ship): for event in pygame.event.get(): if event.type == pygame.QUIT:

要让飞船可以移动，你需要在 `Ship` 类中添加移动的方法，并在 `game_functions` 模块中添加检测按键事件的函数。具体步骤如下：

1. 在 `Ship` 类中添加 `move_right()` 和 `move_left()` 方法，用于将飞船向右或向左移动一定的距离。

class Ship():
    def __init__(self, screen, ai_setting):
        ...
        
    def move_right(self):
        self.rect.centerx += self.ai_setting.ship_speed_factor
        
    def move_left(self):
        self.rect.centerx -= self.ai_setting.ship_speed_factor

2. 在 `game_functions` 模块中添加 `check_keydown_events()` 和 `check_keyup_events()` 函数，用于检测按键事件，并调用飞船的移动方法。

def check_keydown_events(event, ship):
    if event.key == pygame.K_RIGHT:
        ship.move_right()
    elif event.key == pygame.K_LEFT:
        ship.move_left()

def check_keyup_events(event, ship):
    if event.key == pygame.K_RIGHT:
        # 停止向右移动
    elif event.key == pygame.K_LEFT:
        # 停止向左移动

3. 修改 `check_event()` 函数，调用检测按键事件的函数。

def check_event(ship):
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()
        elif event.type == pygame.KEYDOWN:
            check_keydown_events(event, ship)
        elif event.type == pygame.KEYUP:
            check_keyup_events(event, ship)

4. 在 `run_game()` 函数中调用 `check_event()` 函数。

def run_game():
    pygame.init()
    ai_setting=Settings()
    screen=pygame.display.set_mode((ai_setting.screen_width,ai_setting.screen_height))
    pygame.display.set_caption("alien invasion")
    ship=Ship(screen,ai_setting)
    while True:
        gf.check_event(ship)
        ship.update(screen)
        gf.update_screen(ai_setting,screen,ship)
        pygame.display.flip()

run_game()

这样就可以让飞船可以通过方向键进行左右移动了。
