self.rect.left,self.rect.top = location

这一行代码将球体的初始位置设置为location参数中传入的位置坐标。在Pygame中，使用rect属性来表示精灵对象的位置和大小。rect是一个包含四个整数值的元组，分别表示精灵对象的左上角x和y坐标以及宽度和高度。在这里，我们使用location参数中传入的x和y坐标来设置球体的初始位置，即将球体的左上角坐标设置为(location[0], location[1])。由于球体的大小和位置是通过rect属性来管理的，因此我们可以使用self.rect来访问和修改球体的位置和大小。

帮我把下面代码添加注释class Button: def __init__(self, text='按钮', left=0, top=0, width=90, height=30, color=(200, 200, 200)): self.text = text self.color = color self.rect = pygame.Rect(left, top, width, height) self.font = pygame.font.Font(r"C:\Windows\Fonts\simsun.ttc", 16) self.text_surface = self.font.render(self.text, True, (0, 0, 0)) self.text_rect = self.text_surface.get_rect() # self.text_rect.center = self.rect.center self.active = False self.function = None button_group.append(self) def set_text(self, new_text): self.text = new_text self.text_surface = self.font.render(self.text, True, (0, 0, 0)) self.text_rect = self.text_surface.get_rect() def draw(self, screen): if self.active: pygame.draw.rect(screen, (180, 180, 200), self.rect, 0) else: pygame.draw.rect(screen, self.color, self.rect, 0) self.text_rect.center = self.rect.center screen.blit(self.text_surface, self.text_rect) def get_click(self, event): if event.type == pygame.MOUSEBUTTONDOWN: if event.button == 1: mx, my = event.pos if self.rect.left <= mx <= self.rect.right and self.rect.top <= my <= self.rect.bottom: self.active = True elif event.type == pygame.MOUSEBUTTONUP and self.active: if event.button == 1: mx, my = event.pos if self.rect.left <= mx <= self.rect.right and self.rect.top <= my <= self.rect.bottom: # print(f'{self.text}按钮被点击') if callable(self.function): self.function() self.active = False def click_connect(self, function): self.function = function

        screen.blit(self.text_surface, self.text_rect)

    def get_click(self, event):

问题出在第21行，应该将`self.screen_rect = self.screen.get_rect()`改为`self.screen_rect = self.screen.get_rect()`，即将`screen`改为`screen_rect`。代码如下：

class HeroPlane(pygame.sprite.Sprite):
    def __init__(self,screen):
        pygame.sprite.Sprite.__init__(self)  #初始化精灵类
        self.image1 = pygame.image.load("D:/PYTHON/pointgame/hero1.jpg")
        self.rect = self.image1.get_rect() #获取图片大小
        self.rect.topleft = [300,700] #获取飞机左上角坐标
        self.speed = 10  # 飞机速度
        self.screen = screen
        self.screen_rect = self.screen.get_rect()
        self.bullets = pygame.sprite.Group() #group方法 类似列表
        
    def key_control(self):
        # 键盘输入
        key_pressed = pygame.key.get_pressed()
        if key_pressed[K_w] or key_pressed[K_UP]:
            self.rect.top -= self.speed
        if key_pressed[K_s] or key_pressed[K_DOWN]:
            self.rect.bottom += self.speed
        if key_pressed[K_a] or key_pressed[K_LEFT]:
            self.rect.left -= self.speed
        if key_pressed[K_d] or key_pressed[K_RIGHT]:
            self.rect.right += self.speed
        if key_pressed[K_SPACE]:
            bullet = Bullet(self.screen,self.rect.left,self.rect.top) #飞机参数调用
            self.bullets.add(bullet) #把子弹放入列表 
        if self.rect.left < 0:# 控制player不能离开屏幕
            self.rect.left = 0
        elif self.rect.right > self.screen_rect.right: # 修改这行
             self.rect.right = self.screen_rect.right

这样应该就能解决报错问题了。
