How do I use repeat until a value is not nil, I am trying to do this but it is not working

local robotName = sellOrder:FindFirstChildWhichIsA("StringValue")
		
repeat wait() until robotName == sellOrder:FindFirstChildWhichIsA("StringValue")
#2

Edit* all I had to do was switch the two lines around, and it worked

#3

You’re looping for something that doesn’t exist.
Instead, take the name of it and use WaitForChild():

local robotName = sellOrder:WaitForChild("StringValue")
#4

I am not using WaitForChild because the name of my string value is a UID

#5

That doesn’t mean anything.

In my example, the variable halts the script until it exists.

#6

repeat wait() until robotName == sellOrder:FindFirstChildWhichIsA(“StringValue”) ~= nil

(i think, not sure if it’ll do)

#7

Anyways I already fixed the problem, so it doesn’t really matter now

#8

Thanks for helping! But I already fixed the glitch

It still works thought so…
char limit

#12

what he is saying is, it works but its recommended to use his method

#13

I’ll try out his method as well right now!

#14

This is not working it is saying,

--Infinite yield possible on 'ReplicatedStorage.SellOrders.{1389D881-B01F-472C-94FB-7DE6516BB2F0}:WaitForChild("StringValue")'
#15

That’s because you didn’t retitle the name of the value to the ACTUAL value’s name, silly!

#16

Like I’m saying the name of the value is a UID so it is completely random so I can not retitle the name

#17

Use player.UserId for finding the value then. It’s not that hard…

#18

You are misunderstanding me a LOT.
The string value’s name is a UID(not the player id)
So it is a 32-hexadecimal-value which is never the same each time you play the game, so if the player id is 1111112, the UID can be {1389D881-B01F-472C-94FB-7DE6516BB2F0}

You do you, but using a hex value seems strange. I don’t have any extra context on what it’s supposed to do, so I guess I shouldn’t be picky.

Also, UID can be confused with user id (not called player id btw), plus I didn’t originally have any idea on what the other version of a UID is.

I called it player id so you won’t misunderstand me another time.
