Introduction First of all, I want you to change the way you view a generic for loop. next is a builtin function used to give functionality to pairs (not ipairs) and allows us to loop through dictionaries easily. for returns in iter, invariant, init do end returns is just the variables that get the returns of the function iter.

This is required to stop multiple frames to clone, all displaying the same username. Some examples of use cases are: Traversing user-made linked lists Custom traversal behaviour for user-made binary trees Custom traversal behaviour for user Basically a random part selected changes material, color and transparency, tried looking some of the tutorials, nothing seen so far.

(Can’t use ipairs) Zerxiase (Boomy) April 21, 2021, 5:14pm #2. At first glance I’d expect generic for loop to be the fastest, ipairs slightly faster than pairs and generalized iterator extremely close behind, but I guess it depends on the implementation, since we know Roblox improved the execution time of ipairs over for i=1, #t do. for _, v in ipairs(obj:GetChildren()) do local value = v end For looping through children. The values (e.

You would use ipairs on arrays when you need the results in a particular/linear order, say for example your creating a shop gui and want the elements to be created and shown in a particular order you could store the data in a array in the desired order, and iterate over it in the correct order using ipairs, the pairs iterator returns the items in any order, and should really Hello, I don’t quite know how to use pairs and ipairs and i don’t know if this edit is wrong because with it it doesn’t work anymore.
