Find Distance Script?

So, I'm working on a script that will find the distance between an NPC and (currently) 2 blocks, and move the NPC to which ever block is closest. I'm making the script using Region3 so that it senses all blocks in the area, that way I can add more or less blocks to the area without having to re-write the script. Here's my script:

local base = game.Workspace.Base

local point1 = Vector3.new(0,0,0)
local point2 = Vector3.new(100,100,100)
local Region = Region3.new(point1,point2)

for _,Part in pairs(game.Workspace:FindPartsInRegion3(Region,nil,100)) do
	if Part.Name == "building" then
			
		end
	end

I'm super stuck at this point. I've tried for hours, but I can't figure out how to make the script get each blocks position individually, instead of combining all the positions into one variable "Part".

Any help on what to do from this point?

To get the distance between parts, use the following method:

local base = game.Workspace.Base

local point1 = Vector3.new(0,0,0)
local point2 = Vector3.new(100,100,100)
local Region = Region3.new(point1,point2)

local parts = game.Workspace:FindPartsInRegion3(Region,nil,100)
---------------------------------------------------------------------------------------- This is the part that gets the magnitude.
local pos = {} -- table for parts
local vals = {} -- table for position values

function getMagnitude(part1,part2)
	local mag = (part1.Position - part2.Position).magnitude
	return mag
end

for i = 1,#parts do -- so you can get current number
    if parts[i].Name == "building" then
		table.insert(pos,parts[i])
		table.insert(vals,getMagnitude(base,parts[i]))
        end
end
------------------------------------------------------------------------------------------
wait()

local lowest
local pTable = {}

function getPart(m)
	for i = 1,#parts do
		if getMagnitude(base,parts[i]) == m then
			table.insert(pTable,parts[i])
		end
	end
end

for i = 1,#vals do
	if lowest ~= nil then
		if lowest <= vals[i] then
			lowest = vals[i]
		end
	else
		lowest = vals[i]
	end
end

wait()
getPart(lowest)
wait()

if #pTable > 1 then
	local str
	for i = 1,#pTable do
		str = str.. ", " ..pTable[i].Name
	end
	wait()
	print(str.. " are the closest with a tied magnitude.)
else
	print(pTable[1].Name.. " is the closest.")
end

This script also gets the closest one.

This should work, and hopefully you can fix any bugs (if there are any).

This is very unnecessarily complicated. You need only .magnitude.

Yes. Lol, just so he can use it expanded without changing much.
