Accessing Player's model from a normal script?

Hello, I have a script that requires the distance between the character (specifically the character's torso) and an object in Workspace. However, I can't find a way to access the Player's model! The code looks a bit like this (cropped to include relevant parts only):

while wait() do
	local magnitude = (script.Parent.Position - game.Players.LocalPlayer.Character.Torso.Position).magnitude
	if magnitude < 10 then
		--code
	elseif magnitude >= 10 then
		--code
	end
end

Obviously this doesn't work because LocalPlayer can only be used in LocalScripts. If anyone could find an answer, that'd be great. Thanks in advance!
