self: Prefix?

[randomGuest]

I've seen it used in g.FindMetaTable but I'm confused as to what self: actually refers to

If it refers to the ply, why can't you just use ply? Is self: referring to the executer of said script?

If you have a meta function, self will be the object the function was called on.

For example, if you have an object with the function :GetBla() then then the function could be defined like this

[lua]
function obj:GetBla()
return self.bla;
end
[/lua]

oh ok: then i'm guessing the metatable's self object refers to that of the current player? (or "player")

edit: pretty much the same thing as referring to the current object

[Man Without Hat]

self is a syntactic sugar variable used in OO lua. The object is defined by

[lua]function obj:Whatever(args)

end[/lua]

Which is equivalent to

[lua]function obj.Whatever(self,args)

end[/lua]

so yes, self refers to the object, which would be a specific player.

For example, if you were to call LocalPlayer():SomeFunc() then it would be basically doing

FindMetaTable("Player").SomeFunc(LocalPlayer())

Or, "Man Whithout Hat" you could not be a noob and do _R.Player.SomeFunc( LocalPlayer() );

Hardly makes him a noob, he contributed and helped the op, you trying to show him up was pointless and only makes you look like a douchebag.

I'm no noob. I've been doing lua since you were 10 and a half. (Based on what you said your age was).

I told that guy the easier-to-understand method of doing it because he probably wouldn't understand the lua registry yet.

what exactly 'is' the lua registry? there's nothing on it

[Man Without Hat]

Lua registry is basically the lua call stack, and a collection of objects. The objects are stored there so as they can be referred to. It is also used for storing data between C and Lua.
