[QUOTE=barz743;44674981]i have an array with information on the server i want to use this information(array) on my client.
(i want to send this array from server to client)[/QUOTE]Unless someone else can answer your question from what you've said, I personally can't. Can you please give an example or something? I understand that you have an array and that you want to use it on the client but what exactly are you trying to do?

Check for the net library

[lua]

//Server

util.AddNetworkString("SendMyOrder") //This will avoid an unpolled message

function createOrder(ply)
local tbl = {"Cheese",42,true} //A table with any kind of data
net.Start("SendMyOrder") //We start our interaction with the client
net.WriteTable(tbl) //We write our table for send it
net.Send(ply) //We send this table to the player ply
end

//Client

net.Receive("SendMyOrder",function(len)
local tbl = net.ReadTable() //We assign the table that we wrote before

PrintTable(tbl) //Will print cheese,42 and true
end)

[/lua]

Info[1] = ply:name
info[2] = text
info[3] = number (1)
info[4] = color
I want to trasfer this deta from my server to my client(how can i do it)

Use net.SendToServer( ); from client to server, use net.Send( Player ); to send to one player from the server, or net.Broadcast( ); to send to all players from server.

To read and write a table, regardless of whether its from client to server or server to client, you'll use net.WriteTable( tableReferenceVariableGoesHere );
and to read it from the receiving side:
local _myTable = net.ReadTable( );

Edit: Whoops, had this question open a little too long before responding...

Use the net library;

[lua]//SERVERSIDE STUFF

util.AddNetworkString( 'SendTable' ) -- Pool the net name so it can actually be sent

function TableToClient( pl, text, number, color ) -- Customise your function
local Info = { pl:Name(), text, number, color } -- Your table

net.Start( 'SendTable' ) -- Start the net message
net.WriteTable( Info ) -- Write the table into the net message
net.Send( pl ) -- Send it to a specific player
end

//CLIENTSIDE STUFF

function ReceiveNet()
local tbl = net.ReadTable() -- Read the table sent from the server

for _, v in pairs( tbl ) do
chat.AddText( Color(255,255,255), v .. ' read from server' ) -- This is just to debug it
end
end
net.Receive( 'SendTable', ReceiveNet )[/lua]

Ty every one!!
I got one more problem, Do you guys know how to make a lua script 'wait', in clientside?
I need a command to executed 5 seconds after a function.

Hey guys..
Apperantly i got an error on my code, it is when i try and read the table i sent.
I am getting this error:
[ERROR] lua/includes/modules/net.lua:136: attempt to concatenate local 'typeid' (a nil value)
1. ReadType - lua/includes/modules/net.lua:136
2. ReadTable - lua/includes/modules/net.lua:84
[B]3. v - addons/worldsay/lua/autorun/client/cl_client.lua:3[/B]
4. unknown - lua/includes/modules/hook.lua:84

on this code:

  local Value = net.ReadTable() 

[TaintedTurnip]

Could you post the function containing that code and the net.Receive that's calling the function?

It's because you're trying to do net.ReadTable() when the hook calls the function, and there's nothing to read since no net message has been received when the hook is called, you need to ensure the table is set before the hook is called, meaning you'd need to wrap the code within the function in an if statement, checking if the net.ReadTable actually returns anything.

[lua]
local Value = {}
function Draw( ply )
if ( net.ReadTable() ) then
Value = net.ReadTable()
local offset = Vector( 0, 0, 85 )
local ang = LocalPlayer():EyeAngles()
local pos = Value[1] + offset + ang:Up()
ang:RotateAroundAxis( ang:Forward(), 90 )
ang:RotateAroundAxis( ang:Right(), 90 )

cam.Start3D2D( pos, Angle( 0, ang.y, 90 ), 0.25 )
draw.DrawText( Value[2], "ChatFont", 2, 2, Value[3], TEXT_ALIGN_CENTER )
cam.End3D2D()
end
end
net.Receive( 'ChatColor', Draw )
hook.Add( "PostPlayerDraw", "DrawName", Draw )
[/lua]

This should work in theory, but I've not tested it. There's probably an easier way to do it, like checking if a net message has actually been received by a specific name.

First of all Thanks!
But when i look at my player, I am getting this error for some reason:
[ERROR] lua/includes/modules/net.lua:136: attempt to concatenate local 'typeid' (a nil value)
1. ReadType - lua/includes/modules/net.lua:136
2. ReadTable - lua/includes/modules/net.lua:84

4. unknown - lua/includes/modules/hook.lua:84

[MeepDarknessM]

-snip- the code is terrible and won't work

Is that using the code I just provided?

[Acecool]

Here's an example of how to have the client render / display something for X seconds within a hook, then remove itself after.

The example sends a net message to the client when they connect, the client receives it and adds a hook to render and sets the time it started, when the time expires within the hook it is removed.

I'd recommend separating them out just a bit because the net.ReadTable( ) will only exist for 1 frame...

Notice on the client-net-receive; it adds a hook that manages itself. That's how something like that should be done ( rather, its one way to properly execute it )..
