How to use magnitude without looping for detecting distance? [Solved]

So recently I've been working on something and I was doing fine but I have came to a stop because of a blockage, rendering me unable to continue.

If anyone can possibly help, it would be VERY appreciated.

Here is my current script:

--[[ Variables ]]--
local plr = game.Players.LocalPlayer
char = workspace:WaitForChild(tostring(plr.Name))

local ID = workspace:WaitForChild("Interactive_Doors")
local II = workspace:WaitForChild("Interactive_Items")

local Available = false
local item


--[[ Functions ]]--

function Use()
    if Available == true then
        print("picked up item")
        if item then
            item.Parent = plr
        end
    end
end


--[[ CONTROL BINDING ]]--
local controls = game:GetService("ContextActionService")

controls:BindAction("Interact", Use, false, Enum.KeyCode.E)

for i,v in ipairs(II:GetChildren()) do
    while true do
        if (char.Torso.Position - v.Position).magnitude <= 5 then
            Available = true
            item = v
        else
            Available = false
            item = nil
        end
        wait()
    end
end

At the bottom for the last bit of code, you can see I am using a while true do loop to continue checking to see if a player is near certain parts that are in a folder called "Interactive_Items".

I was wondering if there was a way to make this better or more efficient without using a loop, or at least a BETTER way of doing it with loops?

The reasoning of asking this is because I have two folders for two different types of interactions. But the issue I seek to solve is that when it goes into that loop, it gets stuck on those lines making it so I can't do a second ipairs loop for the other folder.

If you don't understand what I'm trying to explain, just let me know and I'll try my best to explain again.

Thanks again! :)
