[PROBLEM]Chat Command

[JohnLehn]

function dchat ( thePlayer, _, ... )
    local message = table.concat ( { ... }, " " )
    if ( isPlayerOnGroup ( thePlayer ) ) then
        for _, player in ipairs ( getElementsByType ( "player" ) ) do
            if ( isPlayerOnGroup ( player ) ) then
                outputChatBox ( "#0066cc[Unit ".. numbers .."]#0066cc".. getPlayerName ( thePlayer ) ..": #0066cc".. message, player, 255, 255, 255, true )
            end
        end
    else
        outputChatBox ( "#838b83Error!", thePlayer, 255, 255, 255, true )
    end
end
addCommandHandler ( "d", dchat )

function randomnum(player) 
local numbers = tostring(math.random(1,100)) 
    outputChatBox ( " The random number is ".. numbers ..". ", player ) 
end 

When you say something on chat /d, i want to appear [Unit (random number)] <playername> : <Text>

The error with this code is : Error: Dispatch\Server.Lua:6 attept to concatentate global 'number' (a nil value)

Can someone help me ? Please ?

Hello, you are using numbers on line 6 in the outputChatBox but you didnt assign any value to it.

you should add this to the dchat function and i guess it should work.

local numbers = tostring(math.random(1,100))

Thanks ! It worked ! How can i make it to be only one number per user, when i type /d <text> look how it is working:

[Unit 46]BigNighT: s
[Unit 36]BigNighT: f
[Unit 6]BigNighT: s

You can work with set- and getElementData.
Just give your users a ID with setElementData, after he loggedin or connected, and use getElementData to ask for it and use it in your chatbox.

You could use something like this:

local ID = 0;

function givePlayerID(player)
	ID = ID + 1;
	setElementData(player,"PlayerID",ID);
end

addEventHandler("onPlayerJoin",root,function()
	givePlayerID(source);
end)

for _,v in pairs(getElementsByType("player"))do
	givePlayerID(v);
end)

Now you can use getElementData to get the PlayerID who will be the same until the player disconnect or the script will be restarted. If you want that all players have everytime the same ID you must work with a database or a textfile or something else to save them.
