也不是正中间啊

抱歉，看起来是文本的渲染方式导致的。为了使文本更精确地居中，可以在绘制文本前计算文本宽度的一半，并将其减去屏幕宽度的一半。这样可以确保文本在屏幕中心位置上。修改代码如下：

1. 在  Text  类中添加一个方法  draw_centered ，用于计算并绘制居中的文本：

class Text:

# 省略其他代码...

def draw_centered(self, surface):

      self.surface = self.font.render(self.text, True, self.color)

      self.rect = self.surface.get_rect()

      self.rect.center = (width // 2, height // 2)

      surface.blit(self.surface, self.rect.topleft)

复制代码

2. 更新  state == 3  的情况，使用新的  draw_centered  方法绘制居中的文本：

elif state == 3:

succed.text = f'{thread.result[0]}(用户组: {thread.result[2]})'

succed.color = thread.result[1]

succed.draw_centered(screen)

复制代码

这样，当登录成功后，用户名和用户组信息将准确显示在屏幕正中间。

从您提供的代码来看，登录成功后，用户名显示在右上角是由以下代码实现的：

succed = Text('', font15, (0, 0, 0), (width - 150, 10))

复制代码

这行代码创建了一个名为 succed 的 Text 对象，将其初始位置设置为屏幕右上角附近。具体来说， width - 150 使文本距离屏幕右侧 150 像素， 10 则是距离屏幕顶部的像素数。当登录成功时， state 变为 3，下面的代码将用户名和用户组信息显示在屏幕上：

elif state == 3:

succed.text = f'{thread.result[0]}(用户组: {thread.result[2]})'

succed.color = thread.result[1]

succed.rect.topleft = (width - succed.rect.width - 10, 10)

succed.draw()

复制代码

在这段代码中，首先更新 succed 的文本属性，包括用户名和用户组信息。接着，根据文本的宽度，重新计算并设置文本的位置，使其始终保持在屏幕右上角附近。最后调用 succed.draw() 方法将文本绘制在屏幕上。

似乎并没有回答问题

要将用户名显示在屏幕正中间，首先需要在每次更新文本内容时计算正确的位置。可以通过以下方法调整代码来实现：

1. 修改  succed  对象的初始化位置，使其在屏幕正中间。这里，我们将其位置设置为  (width // 2, height // 2) ：

succed = Text('', font15, (0, 0, 0), (width // 2, height // 2))

复制代码

2. 在登录成功时，更新  succed  对象的位置，使其始终保持在屏幕正中间：

elif state == 3:

succed.text = f'{thread.result[0]}(用户组: {thread.result[2]})'

succed.color = thread.result[1]

succed.rect.center = (width // 2, height // 2)

succed.draw()

复制代码

这里，我们将  succed.rect.topleft  替换为  succed.rect.center ，并将其位置设置为屏幕中心点  (width // 2, height // 2) 。这样，在登录成功后，用户名和用户组信息将显示在屏幕正中间。

      self.rect.center = (width // 2, height // 2)

      surface.blit(self.surface, self.rect.topleft)

复制代码

2. 更新  state == 3  的情况，使用新的  draw_centered  方法绘制居中的文本：
