Element tables and math.random

[DRW]

Hello, I'm currently working on a gamemode, but I have a problem, because I need to script something that sets an elementdata to some of the currently online players. Take the Gmod's gamemode "Trouble in Terrorist Town" for example, that gamemode gets all the online and alive players and sets the "traitor" data to a minority portion of the current online players. I know I should use something like getElementsByType or getPlayerCount, and probably math.random, but I know it won't work how it has to work, because it may select randomly two times the same player, and I don't want that. Any help?

setElementData

I was clearly not asking for setElementData, just asking how to use math.random to set an elementData to one third part of the total online players.

local players = getElementsByType ( "player" ) -- get all players connected 
  
local thirdpart = math.floor(#players / 3) -- get 1/3 count of those players 
  
-- you could use many other loop method, I'd probably use this one though 
local i = 1 
  
while i  <= thirdpart do 
     local value = math.random(0, #players ) -- generates a random value between "0" and the amount of players 
                 if isElement(players[value]) then 
                                  setElementData(players[value], string, data) 
                                  i = i + 1  
                 end 
end 
  
  

EDIT: Edited my post, totally forgot you wanted it to be random.

or actually, totally forgot about a function

https://wiki.multitheftauto.com/wiki/GetRandomPlayer

  
local players = getElementsByType ( "player" ) -- get all players connected 
local thirdpart = math.floor(#players / 3) -- get 1/3 count of those players 
  
local i = 1 
while i  <= thirdpart do 
       local random = getRandomPlayer() 
       setElementData(random, string, data) 
       i = i + 1 
end

tweak

When there are 0 players the while loop will still be executed.

A simple > if #thirdpart > 0 then < on line 4 would do the fix.

Also count i = i+1 some where else...

Thank you very much!

what about.. note: i am posting from my phone so i can't enter wiki and get correct functions

function Random () 
local Player = getRandomPlayer() 
local Count = getPlayerCount() 
if Count == 0 then return end 
 if Player then 
    if getElementData ( Player, key ) == value then return end 
    setElementData ( Player, key , value ) 
end 
end 
setTimer(Random, your_time_in_secs*1000, 0)
