You don't need any C++ or a real programming language. Just your server-side web PHP, JSP, ASP.NET, or Node.js.
Are you saying server-side languages aren't "real" programming languages?
Also, for his information, there are a
lot more server-side languages than that, those are just a few of most frequently used (Although not necessarily in order)
He will still need TorqueScript though.
all I need to worry about is the Cpp part.
As hammer said, you don't need C++, Blockland uses Torquescript for add-ons, the only time you'd need C++ is if you want to make a standalone executable utility, or something to hook into Blockland to accomplish things that Torquescript can't, etc
