ClassName returns nil?

Help and Feedback Scripting Support

Hello! So I have the following script:

local children = script.Parent:GetChildren()
-- Clearing not needed crap inside the PlayerGui instance

local cutscenegui = script.Parent:WaitForChild("Cutscene")

cutscenegui:FindFirstChild("SkipCutscene").MouseButton1Click:Connect(function()
	for i = 1, #children do
		if script.Parent:FindFirstChild(children[i]).ClassName == "LocalScript" or script.Parent:FindFirstChild(children[i]).ClassName == "Folder" then table.remove(children, i) end
	end
	for i = 1, #children do
		script.Parent:FindFirstChild(children[i]).Enabled = true
	end
end)

I am getting the following error:
Players.Kostiskat.PlayerGui.LocalScript:8: attempt to index nil with 'ClassName'
(line 8)

Help would be appreciated!

It is calling a number on a child so it thinks it is this:
part1

Change this

To this
:FindFirstChild(children[i].Name)
Since you are searching with an instance and not a name

Also it was trying to call the child with a number

No. Its getting a member from a table using [number]

I have gotten an error like this before. I believe it is because the Instance you are trying to find doesn’t not have a class name because it probably doesn’t exist. I would recommend putting a:

print(script.Parent:FindFirstChild(children[i]))

right before that line and see what it prints in the output.

Maybe try :WaitForChild(). If there is a warning then it doesnt work

Also i would recommend to use :IsA() instead
This
if script.Parent:FindFirstChild(children[i].Name):IsA("LocalScript")
is the same as
if script.Parent:FindFirstChild(children[i].Name).ClassName == "LocalScript"

Thats because you are searching it using an instance. Not a string

Try this instead
print(script.Parent:FindFirstChild(children[i].Name))

Okay, it prints the class names properly too, but it return nil for folder instances. Would :IsA do the upposite?

13

I don’t know how you would implement it since :IsA() is only using for if statements and stuff

14

Ok so that basically means that nothing the table is getting actually exists or something is causing whatever was there to disappear. I would recommend trying what [zaydoudou] suggested but it might not work because if the instance doesn’t exist, how could it have a name?

It is getting it from the table. Its just finding the child through an instance and not through a string

Turns out there’s actually another problem, since there are Roblox core instances created inside the player gui.
