Checking if one of many values changes

Help and Feedback Scripting Support
#1

So i have more than 1 value inside a folder, and i want to check if one of them changes.
what im confused about is that i cant just use “value.Changed” because i dont know which value changed.

i though of using for loops but cant find where to use them
this might or might not help you understand my question:

local folder = game.ReplicatedStorage.Folder

-- "the value that changed inside that folder".Changed:Connect(function()
--      print(the value that changed inside that folder.."Changed")
--end)

Thanks in advance!

local folder = game.ReplicatedStorage.Folder
for _, value in ipairs(folder:GetChildren()) do
value.Changed:Connect(function()
print(value.Name)
end)
end

Within the function ‘value’ would be the value (instance) that was changed.

i had to add a while true do for that to work, but i thought it had limits? like it could stop after a while

#4

Is this a localscript or a serverscript?

#5

it’s a server script, i cant change it to a local one

#6

Use:

repeat
--code
until

So it will stop when something is triggered.

Long and behold, the script that should solve this:

local function SomeFunction(value)
print(value.Name)
end
local folder = game.ReplicatedStorage.Folder
for _, value in ipairs(folder:GetChildren()) do
value.Changed:Connect(function()
SomeFunction(value)
end)
end
folder.ChildAdded:Connect(function(value)
value.Changed:Connect(function()
SomeFunction(value)
end)
end)

SomeFunction’s value is the value that was changed.

im not instancing the values tho, they’re already in the folder does it still work that way?

#9

it should keep going forever tho, there’s no “until”

#10

Yes, that what the for loop is for, it should pick up already created values.

#11

i will try that and let you know, thanks a lot!

#12

If it doesn’t work try adding a task.wait(1) in front of the piece of code as it may be an error with the values not existing when the for loop was called.

#13

it works perfectly fine, the value only changes when the player changes it, so there shouldn’t be any errors, as the values already exist when the player does that.
