Could I please have some basic "Functions" help?

I'd simply like to know, just how to Function objects and weapons, maybe.

There is no "simple" way to script objects or weapons.

To learn Lua, I suggest checking out this article on scripting for beginners. Also, browse Free Models and explore their scripts, as well as viewing the threads on this forum to see what people have done wrong with their scripts.

I did just that, and I learned a bit of Lua myself.
