# hmmm, what you need ?

It's obvius ... A teacher has stutends and he want to only talk to them.

@scaryface87: you used this instruction to get the class:

local classmembers = getElementData(player,"class")

but how do you set it ? Can you show us how you create the table and how do you set it as an element data ? Thanks

Im a little bit confused?

It sets the element data on playerspawn (i already used getElementData for other things so dont rlly htink its a problem there)

h"how you create the table" what u meaN?

[Citizen]

I meant:

"Can you show the code where you are setting this "class" element data ?"

Because this data should be a table, and I want to see how did you make this table (how did you fill it).

[scaryface87]

im just using

setElementData(player, "class", className)

[Citizen]

And what is className ?

Come on, give us the code we need, not 1 line after the other.

Your code was expecting a table and not a class name as a string.

The error says it got nil instead of a table. So it means the value of className here

setElementData(player, "class", className) 

is nil.

So give us the code above that line !

+ If you want to use a classe name instead of a table of class members, then use this code (based on iAbo's code):

function classchat(player, command, ...) 
    local message = table.concat({...}, " ") 
    for i,v in ipairs(getElementsByType("player")) do 
        if getElementData( player, "class" ) == getElementData( v, "class" )  then 
            outputChatBox("*CLASS*" .. getPlayerName(player) .. ": " .. message , v, 255, 100, 0, true) 
        end 
    end 
end 
addCommandHandler("class", classchat) 

Note (and I repeat) the code will still not work untill you fix the className value for the setElementData
