我还没有写完，但是第 $133$ 行（将近末尾）这一行

if (CmdName == "SLACKOFF") cmd = new SlackOff((CommandData)cmddata);

出错，两个错误（我用的 Visual Studio）：

1. error C2665: “SlackOff::SlackOff”: 没有重载函数可以转换所有参数类型

2. 可能是“SlackOff::SlackOff(SlackOff &&)”
	main.cpp(133,49):
	“SlackOff::SlackOff(SlackOff &&)”: 无法将参数 1 从“CommandData”转换为“SlackOff &&”
		main.cpp(133,50):
		原因如下: 无法从“CommandData”转换为“SlackOff”
		main.cpp(133,50):
		没有可用于执行该转换的用户定义的转换运算符，或者无法调用该运算符

求帮助……
