Help with this line?

[Temex]

I am trying to edit a simple lua script.
I don't know what that code is for what the player is currently holding.
I took a wild guess and came up with this

if ( [b][i]player.GetCurrentWeapon[/b][/i](self.Owner) ) then

Well, to start off there is no such function. It is called [b][url=http://wiki.garrysmod.com/?title=Player.GetActiveWeapon]Player.GetActiveWeapon [img]http://wiki.garrysmod.com/favicon.ico[/img][/url][/b] and since Lua is an object oriented language, functions work on objects like this:
[lua]if ( self.Owner:GetActiveWeapon() ) then[/lua]
This is essentially the same as this:
[lua]if ( _R.Player.GetActiveWeapon( self.Owner ) ) then[/lua]
You can read how this works [url=http://wiki.garrysmod.com/?title=Metatable][b]here[/b][/url].

[QUOTE=Overv;24038432]and since Lua is an object oriented language[/QUOTE]

[i]Technically,[/i] lua is a functional programming language, not object oriented.

Temex, you need to tell us how it's not working or what errors you're getting so we can help.

[Temex]

Sure Well, I try to spawn it through console 'give tmx_stunstick' and it says that it doesn't exist.

[editline]05:02PM[/editline]

Null entity or something...

[commander204]

There should be an error somewhere with your file name, copy the whole line.

[Temex]

Nope there isn't.

[editline]05:13PM[/editline]

All I want is so that for someone to look through the whole script, find anything that wouldn't work unless its with HL2RP Gamemode, edit it so it is a separate swep that can work on it's own, then post it!

[QUOTE=yakahughes;24038685][i]Technically,[/i] lua is a functional programming language, not object oriented.[/QUOTE]

True, but Lua is a [url=http://en.wikipedia.org/wiki/Lua_%28programming_language%29]multi-paradigm language[/url] so you can also see it as an [url=http://www.lua.org/pil/28.3.html]object-oriented language with the meta table features[/url].

[Temex]

Can you guys stop arguing about that, and help me ? :S

Where did you place the SWEP files/folder?
