这是一个用 Python 语言编写的 tkinter 图形界面程序。主要实现了一个登录界面,用户需要输入用户名和密码,选择游戏,如果输入的用户名和密码正确,就可以进入对应的游戏界面。其中,游戏分为三个,分别是 Game1、Game2 和 Game3。
程序的具体实现如下:
1. 导入 tkinter 库及其相关模块:
```python
import tkinter as tk
from tkinter import *
import tkinter.messagebox # 弹窗库
import numpy as np
```
2. 定义 Game1、Game2、Game3 三个类,每个类分别对应一个游戏界面,实现了一个 Label 控件,用于显示游戏名称。
3. 定义 Login 类,实现了登录界面,包括用户名和密码的输入框,以及选择游戏的按钮。当用户输入用户名和密码之后,点击游戏按钮,程序会检查用户名和密码是否正确,如果正确就会进入对应的游戏界面,否则会弹出错误提示框。
4. 在主程序中,创建了一个 Tk 对象,并将其传给 Login 类,启动程序的主循环。
在实际运行程序时,需要将 `import A`、`import B` 和 `import C` 替换成相应的游戏模块的导入语句。此外,在检查用户名和密码时,应该使用更加安全的加密算法,以保护用户的信息。
