#1

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!

i want to make it like i want to run a function but it runs everything at the same time

  1. What is the issue? Include screenshots / videos if possible!
    idk how
  2. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    yes
    After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!

there isnt any script, i just want to know how to make everything run at the same time, for example

for i,v in ipairs(game.Players:GetChildren())
    v.PlayerGui.Frame.Visible = true
    wait(1)
    v.PlayerGui.Frame.Visible = false
end

the script will run the for loop for one player at a time, but in my case i want it to run for all the players in the same time.

You need to put the wait after you checked all Players

for example in a while true. (don’t do a while true)

local Players = game:GetService("Players")

while true do
	for i, v in pairs(Players:GetChildren()) do
		v.PlayerGui.Frame.Visible = true
	end
	wait(1)
	for i, v in pairs(Players:GetChildren()) do
		v.PlayerGui.Frame.Visible = false
	end
end

You can create a function for this instead of while true

local function player_frame()
	for i, v in pairs(Players:GetChildren()) do
		v.PlayerGui.Frame.Visible = true
	end
	wait(1)
	for i, v in pairs(Players:GetChildren()) do
		v.PlayerGui.Frame.Visible = false
	end
end

player_frame()

i tried the function but it still doesnt run all the same time: here is my script that i modified because of the problem:

wait(2)
local intermissionLength = 5 -- Time in seconds of the time you in the lobby
local Status = game.ReplicatedStorage.Status
local Players = game:GetService("Players")

local PlayersInGame = {}

local LobbySpawn = game.Workspace.LobbySpawn

	if InRound.Value == true then
		for _, player in pairs(game.Players:GetChildren()) do
			local char = player.Character
			local Clone = workspace.Colors:WaitForChild("Map")
			local randomColorchooser = math.random(1, #Clone:GetChildren())	
			local randomPart: Part = Clone:GetChildren()[randomColorchooser]

that is the function im worrying about

i want the function to run for all the players at the same time, or my game will break

i think i know how to do this in a easier way using local scripts but i would like to know how (because of the title)

#5

you are still putting in your script the wait inside the for loop in my script it’s outside

#6

ok i just figured out a solution.

#7

i just used a local script

thats the solution

#8

With lua you cannot truly run things at the same time - but you can get as close as possible using coroutines, which run tasks on different “threads”

try something like

edit: I’ve just been informed there is parallel lua as of the past year, but not required here

for index, value in pairs() do
 coroutine.wrap(function()
  gui.visible = true
  wait(1)
  gui.visible = false
 end)()
end

then substitue whatever you’re doing for all players in therestrong text

#9

i forgot that coroutine exists, i thought that task is like coroutine

im so dumb

but still, someone in another Topic said that local scripts are the best if you are dealing with UIs.

#10

yeah that’s generally correct - keep your UI stuff in a local script, as UIs are generally unique to the player

I don’t wanna see your coins, and you don’t wanna see mine

#11

true!

idk why i put my UIs using scripts XD

the server cant handle it

#12

haha yep leave that to the client :sweat_smile:

#13

just let the player gets uis everywhere just like a virus duplicating.

#14
