server side

--first function
local jogsA = jogadores:GetChildren()
local jogsF = {}
for i = 1, #jogsA do
    jogsF[i] = game:GetService("Players"):GetPlayerByUserId(jogsA[i].Name).Name
end
ATUALIZARJOGADORES:FireClient(player, jogsF, 1)


--second function
local jogs = game:GetService("ServerStorage").Salas:FindFirstChild(sala).jogadores
local jogsA = jogs:GetChildren()
local jogsF = {}
for i = 1, #jogsA do
    jogsF[i] = game:GetService("Players"):GetPlayerByUserId(jogsA[i].Name).Name
end 

for i = 1, #jogsA do
        local jog = game:GetService("Players"):GetPlayerByUserId(tonumber(jogsA[i].Name))
    if jogsA[i].Name == tostring(host) then
        ATUALIZARJOGADORES:FireClient(jog, jogsF, 1)
    else
        ATUALIZARJOGADORES:FireClient(jog, jogsF, 0)
    end
end

client side

ATUALIZARJOGADORES.OnClientEvent:Connect(function(jogs, aux)
        local P
    local Pc
    local frameM = game:GetService("Players").LocalPlayer.PlayerGui.Main.Frame
    if aux == 1 then
        P = frameM.P5.Frame
    elseif aux == 0 then
        P = frameM.P6.Frame
    end
    Pc = P:GetChildren()
    for i = 1, #Pc do
        if not Pc[i]:IsA("UIListLayout") and Pc[i].Name ~= "Placeholder" then
            Pc[i].Visible = false
            Pc[i]:Destroy()
        end
    end
    print(jogs)
    print("print 1")
    for i = 1, #jogs do
        print("print 2")
        local jog = P.Placeholder:Clone()
        jog.Text = jogs[i]
        jog.Name = tostring(i)
        jog.Visible = true
        jog.Parent = P
    end
end)

when the event is fired by the first function, everything works, when its fired by the second function, not everything works, the table printed is empty, the "print 1" is printed but "print 2" isnt, i have no idea at how the table is being empty when fired by the second function (the whole script isnt written down, feel free to ask for more information if u need)

violet olive server side ``` --first function local jogsA = jogadores:GetChildren() local jog...

Im bit lost in the codebase but are you mixing types of indexes?

#

Not all type of data can be serialized

#

if you use multiple types of indexes for example string and number
One will be nil'ed

#

sometimes serialization can throw out other stuff like custom roblox classes

#

as they aint always serializable

steep spindle Im bit lost in the codebase but are you mixing types of indexes?

what do you mean by indexes here

steep spindle Jan 20, 2026, 8:25 PM

#

violet olive what do you mean by indexes here

local something = {}
something[123] = "value"
something["hello"] = "value"

index is 123 and "hello"

#

i dont think youre actually mixing types

#

but maybe im missing

violet olive Jan 20, 2026, 8:25 PM

#

steep spindle ```lua local something = {} something[123] = "value" something["hello"] = "value...

no, the tables indexes is all numbers

#

1, 2, 3, 4

steep spindle Jan 20, 2026, 8:26 PM

#

i see

#

what exact data are you sending

#

im bit lost in the code

#

is it sending player and players name?

violet olive Jan 20, 2026, 8:26 PM

#

steep spindle what exact data are you sending

from client to server?

steep spindle Jan 20, 2026, 8:27 PM

#

from server to client

violet olive Jan 20, 2026, 8:28 PM

#

first parameter is the player ofc, second is a table of many players names, the third is to tell which GUI to manipulate

#

that table is obtained by another table that is storing the players user id

steep spindle Jan 20, 2026, 8:31 PM

#

violet olive that table is obtained by another table that is storing the players user id

abnd you basically receive empty table?

#

and*

violet olive Jan 20, 2026, 8:31 PM

#

steep spindle abnd you basically receive empty table?

yes

#

if its fired by the second function

steep spindle Jan 20, 2026, 8:32 PM

#

violet olive if its fired by the second function

by 2nd function you mean this?

#

or the whole part

violet olive Jan 20, 2026, 8:32 PM

#

second function on server side

#

the whole part yeah

steep spindle Jan 20, 2026, 8:33 PM

#

alright alr i see

steep spindle Jan 20, 2026, 8:33 PM

#

violet olive second function on server side

I assume roblox doesnt like you sending player thro argument tbf

#

maybe you can try with player id

#

and then just get player on client

#

not sure if thats 100% it but always worth taking a look over

violet olive Jan 20, 2026, 8:33 PM

#

steep spindle I assume roblox doesnt like you sending player thro argument tbf

the first parameter?

steep spindle Jan 20, 2026, 8:33 PM

#

yes

#

oh wait

#

im fucking stupid

#

i forgot how remote works

#

ok wait wait

#

😭

violet olive Jan 20, 2026, 8:34 PM

#

dw

steep spindle Jan 20, 2026, 8:36 PM

#

violet olive dw

if u print the table right after on client event, its still empty right?\

violet olive Jan 20, 2026, 8:36 PM

#

yes

#

the for loop isnt even executed

steep spindle Jan 20, 2026, 8:36 PM

#

violet olive yes

what if you print the table before fire client

#

what does that show

violet olive Jan 20, 2026, 8:37 PM

#

lemme see

violet olive Jan 20, 2026, 8:38 PM

#

steep spindle what does that show

nothing

steep spindle Jan 20, 2026, 8:39 PM

#

violet olive nothing

alright so jogsF is somehow empty
But jogsA isnt as it fires the remote

violet olive Jan 20, 2026, 8:39 PM

#

apparently

steep spindle Jan 20, 2026, 8:40 PM

#

if you set value of table to nil, it will be removed essentially gone
So if its not able to get player by id, it would be nil
But then name would have error, weird, add prints

#

imagine sending-

steep spindle Jan 20, 2026, 8:42 PM

#

violet olive nothing

Add print here inside the loop
