How would I compare the distance between 2 or more parts between another part?

So I was wondering how I would compare the distance between 2 or more parts to another part, and return the part with the lowest distance as I am working on an E to interact system.

I’ve tried to do this, but I wasn’t able to return the actual part, only the lowest number (or in this case distance), if that makes any sense.

When I did get it to return a part, it didn’t actually return the closest part but rather the last part in the table I sent it.

If it helps at all, here is the code I attempted to use:


--FYI, c_part stands for comparison part

function getLowestMagnitude(tbl, c_part)
	
	local magnitudes = {}
	
	local lowestNumber
	local lastNumber
	
	local lowestPart
	
	for i, v in pairs(tbl) do
		local magnitude = (v.Position - c_part.Position).magnitude
		table.insert(magnitudes, magnitude)
	end
	
	for i, v in pairs(magnitudes) do
		
		lowestNumber = v
		lowestPart = tbl[i]

		if lastNumber then
			if lowestNumber < lastNumber then
				lastNumber = lowestNumber
			else
				lowestNumber = lastNumber
			end
		else
			lastNumber = lowestNumber
		end
		
	end

	return lowestPart
end

The issue that I am having here is that it returns the last part in the table, not the part with the lowest distance.

Help would be greatly appreciated!

Try this:

This is a bit different than your original script but it does the job easily!

--FYI, c_part stands for comparison part

function getLowestMagnitude(tbl, c_part)

	local magnitudes = {}

	local lowestNumber
	local lastNumber

	local lowestPart

	for i, v in pairs(tbl) do
		local magnitude = (v.Position - c_part.Position).magnitude
		table.insert(magnitudes, {Part = v, Mag = magnitude})
	end
	
	table.sort(magnitudes, function(a,b) return a.Mag < b.Mag end) -- Sorts table from lowest to highest (If wrong change < to >)
	
	return magnitudes[1]
end

This worked flawlessly, thank you so much!
