Im currently devloping a plugin to connect to a socket server i just wanted to know if there is a socket module or would i have to use luasockets dll?

The engine of MCServer is not LUA, so you have to use Java, I think. o.O

I think he wants the plugin to gather some data from the server.
You would need a lua module included by MCServer for this to work,
or I think loading the luasockets module from within lua.

I already created something for this, and exported it to Lua

Code:
class cTCPLink

{

public:

        cTCPLink();

        ~cTCPLink();

        bool Connect( _cstring  a_Address, unsigned int a_Port );

        int Send( _cstring  a_Data, unsigned int a_Size, int a_Flags = 0 );

        int SendMessage( const _cstring  a_Message, int a_Flags = 0 );

        void CloseSocket();

protected:

        virtual void ReceivedData( char a_Data[256], int a_Size ) = 0;

};

It's not documented anywhere. You basically need to 'extend' it like you extend cPlugin. You need this piece of code for that:

Code:
local TCPLink = {}

TCPLink.__index = TCPLink

function TCPLink:new()

   local t = {}

   setmetatable(t, TCPLink)

   local w = Lua__cTCPLink:new()

   tolua.setpeer(w, t)

   w:tolua__set_instance(w)

   return w

end

Then you can inherit the ReceivedData function like so:

Code:
TCPLink:ReceivedData( Data, Size )

   -- Do stuffs with data

end

Okay im a tad confused as i only ever use pure lua and gmod lua, So what exactly do i need to do with this code?

Here's an example:

Code:
local TCPLink = {}

TCPLink.__index = TCPLink

function TCPLink:new()

   local t = {}

   setmetatable(t, TCPLink)

   local w = Lua__cTCPLink:new_local() -- new_local = Deleted by garbage collector

   tolua.setpeer(w, t)

   w:tolua__set_instance(w)

   return w

end

TCP = TCPLink:new()

if( TCP:Connect("www.mc-server.org", 80) == true ) then

    Log("Sending message")

    TCP:SendMessage("GET http://www.mc-server.org/\n")

end

function TCPLink:ReceivedData( Data, Size )

    Log("Received data: " .. Size )

    String = string.sub( Data, 0, Size )

    Log( String )

end

Thanks dude, i can now start working on my plugin.

On trying your example it crashes after data is recevied, Any ideas?
