How do I make this punch script use magnitude insetad of look vector?

I want to make this to where the people around can get hit instead of the people you are looking at. The Local Script is placed in starterpack. In the local script is a remote event and in the remote event is the server script. In the server script are the animations and sound

---Server Script

To use magnitude you will need to run a for loop each time checking each players range. Anyone within range gets damaged.

Here's a bit of an example:

local plr = game.Players.YourPlayer
local range = 5
local damage = 10

function damageHum(hum)
	hum:TakeDamage(damage)
end

for _,v in pairs(game.Players:GetPlayers()) do
	if plr.Character and v.Character then
		local root1 = plr.Character:FindFirstChild("HumanoidRootPart")
		local root2 = v.Character:FindFirstChild("HumanoidRootPart")
		if root1 and root2 and (root1.Position - root2.Position).magnitude <= range then
			if v.Character:FindFirstChild("Humanoid") then
				damageHum(v.Character.Humanoid)
			end
		end
	end
end
