有一个选项可供您选择，无需借助虚拟机或编写自定义驱动程序。如果你为鼠标命令安装了一个钩子，你就可以在将它们传递给下一个钩子之前更改该钩子中的标志。
由于 windows 如何对钩子进行排队，您需要钩子将标志更改为最后注册的钩子，因此在此示例中，您需要在安装钩子之前启动游戏。
下面是一些示例代码，我使用 pyHook 对其进行了测试以检查结果。出于您的目的，您可能希望将其包装在一个线程中，以便它在后台发生。

请注意，目前我找不到在命令中杀死该线程的方法。 GetMessage处的线程执行块等待消息处理，例如WM_QUIT，因为这发生在C而不是python中，在线程中引发异常不会导致它退出，我尝试了大量的组合，例如SendMessage、PostMessage 和 PostThreadMessage 尝试发送 WM_QUIT 消息但没有成功。而是设置了守护进程标志，当主线程退出时强制它退出。
