I need an example

so what it does is it loops through a thing.

Sounds complicated? i’ll dm you, ill teach you about it.

#3

It kinda does sound complicated but I did hear its useful

#4

its VERY VERY useful, sounded complicated to me too until i found out how it works, its not really that complicated, its more of a beginner thing

pairs() is kinda unpredicatble, but ipairs() not.

You dont need to know the difference, nowadays you dont really need them

so one of the use scenarios can be to find out how many parts are in the workspace.

for i,v in ipairs(workspace:GetDescendants) do print(v.Name)

i is the index,
v is the instance.

For everything it will find, it will print out its name

What do you not understand?

It just loops through a dictionary or table, then it gives you an index and a value

its not super easy to explain (atleast for me)

#19 
for i,v in ipairs(workspace:GetDescendants()) do
print(v.Name) -- prints the name of the instance
print(i) -- prints the number in order of the instances inside (1,2,3,4,etc)
end
-- v is the instance (Part,Model,etc)
