extremely basic for loop not working???

[chrome lagoon]

Basically I'm scripting a tutorial level.
The "setBeam()" function just creates arrows for the player to follow.
As you complete a task, it will set the beam to the next part of the tutorial.

--...

--Variables that matters here
local interact = workspace:WaitForChild("Interact")
local tutorialParts = interact:WaitForChild("Items"):WaitForChild("TutorialParts")

--...

--Function that matters here
local function setBeam(player, enabled, level)
  if level == 1 and enabled == true then
  beam.Attachment0 = level1        
  elseif level ~= 1 and enabled == true then
    print("test")                                --TEST ONE
    for _, parts in tutorialParts:GetChildren() do
      print("test1")                             --TEST TWO
      if parts.Name == tostring(level) then
        beam.Attachment0 = parts.Attachment
      end
    end        
  elseif enabled == false then
    beam.Attachment0 = nil
  end
end

the script works perfectly EXCEPT this line

for _, parts in tutorialParts:GetChildren() do

I have marked it with print("test") and print("test1") and only the first print actually prints.

i have also tried putting the the interact and tutorialParts variable inside the function aswell and it still doesnt run

workspace parts dont always exist immediately

you could do it the lazy way or the correct way

the correct way is to listen for childadded or use collectionservice

the lazy way is to make it a model with atomic streamingmode

thankyou ill give these a try

i thought waitforchild would of been enough

theres no errors either usually i get a 'infinite yeild' error or something with waitforchild

[void jacinth]

waitforchild does not also wait for its descendants

[chrome lagoon]

ohh okay

[void jacinth]

in essence you need to waitforchild for all of the folder's descendants.

okk too easy i can do this within the client script in playerstarter

[void jacinth]

well it's a bit more specific than that, some things will always exist some won't unless streamed. refer to docs https://create.roblox.com/docs/workspace/streaming

cheers for the help btw

[chrome lagoon]

sorry i had to run down to the shops
i just now tested i added "workspace.Interact.Items.Tutorial.ChildAdded:Wait()" and it works perfectly now thankyou!

[void jacinth]

should connect, not wait

coz if they happen to all stream in early, this will wait forever

[chrome lagoon]

so i had to mess with it a bit, the initial problem is that i call this function every time the datastore updates the tutorial level and will prevent it from being called due to the childadded function. so i decided to go with

repeat wait() until #tutorialParts:GetChildren() >= 1
``` this makes sure there's atleast one part loaded but after that will pretty much not wait at all.

i did try to use childadded:connect... but the only place i could put it without it interfering with the game was in the dataInit server script.. which defeats the purpose of trying to load parts on the client

[void jacinth]

this is pretty lazy way

just make the folder a model with atomic streamingmode if you're going to be lazy
