Help with math.random

Help and Feedback Scripting Support
1

I am working on an among us type game, but I’m having some errors with math.random.
Script:

local imposter = game.Players:GetPlayers()[math.random(1, #game.Players:GetPlayers())]

Error:
ReplicatedStorage.MainModule:9: invalid argument #2 to ‘random’ (interval is empty)

2 
local Players = game.Players:GetPlayers()

local Imposter = Players[math.random(1, #Players)]

Try this

3

It still gives me the same error

4 
local PlayerTable = game:GetService("Players"):GetPlayers()

local TerroristOne = PlayerTable[math.random(1,#PlayerTable)]

I am making a Trouble in terrorist town and I scraped it from this. I dont know why it says that error, Can you send your whole module script?

5 
local players = game:GetService('Players')
local replicatedStorage = game:GetService('ReplicatedStorage')

local module = {}

function module.ChooseImposters()
	local plrs = players:GetPlayers()
	local imposter = plrs[math.random(1, #plrs)]

	return imposter
end
6

what is the exact error again?

7

I dont think this will cause a issue but why are you returning imposter?

8

so i can get the imposter using another function

9

ReplicatedStorage.MainModule:9: invalid argument #2 to ‘random’ (interval is empty)

10

Can you please print

print(#plrs)

before imposter

11

This error pretty much says that the second argument(interval) is less than the first argument or nil
Are you sure your function isn’t being run before there is a player in game?

Maybe try printing ‘#plrs’ if its zero you’ll need to wait for a player to get in the game (preferably more than 1 so they aren’t alone but just waiting for 1 will stop the error)

12

I actually used

repeat wait(.1) until game.Players.NumPlayers >= 1

so it fixed it, thanks for your help

NumPlayers is deprecated and its use isn’t advised as its support could be dropped at any moment.

repeat task.wait() until game.Players:GetPlayers() >= 1

function choosePlrs(tab)
local plrs = tab:GetChildren()
local n = math.random(1,#plrs)
local imposter = plrs[n]
return imposter
end

idk if this works
