Attempt to compare number and table - Two random players

Help and Feedback Scripting Support
#1 
if Players:GetChildren() >= 2 then
print(#Participants)
local Player1 = table.remove(Participants, math.random(#Participants))
print(Player1) end

I am receiving this error - ServerScriptService.main:23: attempt to compare number and table
I’m sure its a simple mistake, but I’ve been looking around and nothing pertaining to this on various other forums either that or I’m just blind.
I was using the :GetPlayer() method, but still had the same error - I’m just trying to retrieve a random player from the table of participants, it will end up being two players, but I’m trying to test it in studio first. Thanks in advance.

what do u define on Participants?

Participants = Players:GetPlayers() i presume? Add a hash before Players:GetChildren part

if #Players:GetChildren() >= 2 then
#4

local Participants = {}
– Once they spawn, add them to participants
local function onCharacterAdded(character)
table.insert(Participants, character.Name)
print(character.Name … " has been added to participants.")
end

You use math.random and only give it one value, you give it the number of players. Math.random requires a numbers, the minimum number and the maximum number.

#6

You are comparing a table with a number, you need to get the number of things In the array/table

if #Players:GetChildren() >= 2 then -- missing hash
#7

I can’t get how this would randomly remove a value from the Participants table. Try this:

local RandomPlayer = table.remove(Participants, math.random(1, #Participants))

--[[
This would only get one random value of it.
If the table is not numerical, there might be some issues with doing this.
]]

Edit: Fix.

Heres the thing, I recieve no error from this, but I’m not getting anything in the output. After I hit test play, of course.
if #Players:GetPlayers() >= 1 then
print(#Participants)
local Player1 = table.remove(Participants, math.random(1, #Participants))
print(Player1)
end

edit : nvm I had it. lol

still no output, though???!

Well you say:

local Player1 = table.remove... --more

You are setting a variable equal to that table.remove statement, not to the player that it is removing.
Try this instead:

if #Players:GetChildren() >= 2 then
     print(#Participants)
     local randomnumber1 = math.Random(1,#Participants)
     local player1 = Participants[randomnumber1]
    table.remove(Participants, randomnumber1)
    print(player1)
  
    --- if you want to find the second player then do this also:
     local randomnumber2 = math.Random(1,#Participants)
     local player2 = Participants[randomnumber2]
     print(player2)
end

When using brackets to index something via numbers, if that index exists, it will get it’s value. And table.remove receives a number as #2 index, not a value.

#11

Yeah, I’m still receiving no output?
I’ve even changed if #Players:GetChildren() >= 2 then to >= 1
I’m still getting no output.

How much players are in the game?

@0b4u, your if statement checks if the amount of players is equal to, or higher than 2, and it’s not. And so, it’ll never print.

#13

Try removing the Selected Player outta the Participant List

#14

Maybe before the first line print the number of players in the game.

print(#Players:GetChildren())
#15

Well, its in studio, just me. 30 words are in this message

#16

Well the code requires at least 2 people to be in the game for it to work, therefore it never runs because it’s only you.

#17

I got 0 players in the game, how would I make it wait for me to join, onCharacterAdded I guess, but that seems like I would have to wait on - there has to be a better way…

0 - Server - main:23

#18

Then Run a test server with 4 players?

#19

Usually for this type of thing it is implemented in a round system, where after the intermission it chooses 2 players. How are you using it in your game?

#20

Sometimes, I wonder how I didn’t get to that conclusion myself if I had taken the time to look around.

The Players class has a built-in event for checking whenever a player joins. This event is called PlayerAdded. ( Players.PlayerAdded (roblox.com))
