I really want to learn LUA and make my own hacks. So far all I know how to do is say things in the console and make a table. Can someone link me to a new tutorial or website for Garrys Mod 13.
You should totally look in this section more, there has already been several questions and answers for this.
But this will take some time. It's really abstract at the start but you'll get used to it.
Personally, I just did some basic general lua and I am and have been learning all the gmod stuff by looking at other peoples work and learning by doing.
