pygame.draw.rect(screen, color, self.rect) 如果要画一张图片，我该如何修改我的代码

如果你想在屏幕上绘制一张图片，你可以使用 `pygame.Surface` 对象和 `blit()` 方法。首先，你需要加载你要绘制的图像，可以使用 `pygame.image.load()` 方法，例如：

image = pygame.image.load('example.png')

然后，你可以将图像绘制到屏幕上的指定位置。例如，如果你想在屏幕上绘制一个矩形框和一张图片，你可以修改你的代码如下所示：

# 加载图片
image = pygame.image.load('example.png')

# 绘制矩形框
pygame.draw.rect(screen, color, self.rect)

# 绘制图片
screen.blit(image, (x, y))

其中，`x` 和 `y` 是你想要绘制图片的左上角的坐标。注意，你需要在游戏循环中不断地调用 `pygame.display.flip()` 或 `pygame.display.update()` 方法才能看到屏幕上的更新。

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

以下是代码的注释：

这段代码是一个名为GameBoard的类，用于绘制一个游戏板。它有几个方法：

1. __init__方法是类的构造函数，它接受cell_width、margin、n和screen等参数，并初始化成员变量。它还调用draw_board和draw_buttons方法来绘制游戏板和按钮。

2. draw_board方法用于绘制游戏板的网格线。

3. draw_buttons方法用于绘制游戏板上的按钮，包括QUIT和Restart。

4. draw_first_chess方法用于绘制首个棋子。

5. drawchess方法用于根据给定的行、列和颜色绘制棋子。

6. draw_now_chess方法用于绘制当前棋子。

7. draw_box方法用于绘制一个红色边框的文本框。

该类使用了pygame库来进行绘图操作。
