How do I use GetDescendants() properly?
This has been an important tidbit of code I've needed to learn how to use for a while. Can I use this function to find specific classes (i.e. Part, Folder, Script...), and if so, how? Here's what I've tried so far:
local sP = script.Parent
function totaling()
wait(4)
local wins = sP.AllStats:GetDescendants("Folder")
print(wins)
end
totaling()
Unfortunately I can't figure out what I'm doing wrong because when I run this it doesn't return anything. Thank you for your time!

I think you have to do folder:GetDescendants() seith14 206 — 6y

Instance:GetDescendants() returns a table of all children and descendants of an object. And yes, you can check if something is a Part, Folder, or Script.
local sP = script.Parent
local function totaling() -- avoid global variables and functions unless there's a good reason not to
wait(4)
local wins = sP.AllStats:GetDescendants() -- no arguments
for _, v in pairs(wins) do
if v:IsA("LuaSourceContainer") or v:IsA("BasePart") or v:IsA("Folder") then
-- check if the descendant inherits from class or is that class
-- Code
end
end
end
totaling()

This answers my previous question but also creates another one. What does the "v" mean in the for statement? Beastlance 22 — 6y

v is just the name of the current decendant, It makes a loop untill the last descendant in the folder seith14 206 — 6y

As you can see from the documentation, the GetDescendants function does not take any parameters. It returns an array of the descendants, and as any other table, you can iterate through it.
local descendants = workspace:GetDescendants()
for _, descendant in next, descendants do
print(descendant)
end

Try this
local sP = script.Parent
function totaling()
wait(4)
local wins = sP.AllStats.Folder:GetDescendants()
for _, i in pairs(wins) do
print(i.Name)
end
end
totaling()

Still returning nothing, but if the code worked properly it should be able to return every Folder by it's name correct? Beastlance 22 — 6y

You didn't answer his question. If you're not going to explain you might as well leave a comment. User#19524 175 — 6y
