Re: [NTG-context] How to define such a function in lua? Sorry I don't have a name on it.

but it might make more sense to look into metatables (i assume that you own the programming in lua book which explains that)

I don't have one :(, I'll take a good at it later.

You really should look into the book, it has a whole chapter about object-oriented programming in Lua, and explains useful conventions. Arthur
