so basically im trying to make an npc that follows and attacks you, and it follows you, but it will not attack for some reason, this is the code and the part that isnt working is listed, and its not even giving me errors it just wont work

-- misc vars
local human = script.Parent.Noobanoid
local torso = script.Parent.Torso


-- stats
local config = script.Parent.Config
local health = config.Health.Value
local damage = config.Damage.Value
local speed = config.Speed.Value
local damageSpeed = config.DamageSpeed.Value
local range = config.Range.Value
human.Health = health
human.MaxHealth = health
human.WalkSpeed = speed




-- anim vars
swing = script.Parent.Swing
swingAnim = human:LoadAnimation(swing)
swingAnim.Priority = Enum.AnimationPriority.Action


-- sound vars
local punchSounds = {"rbxassetid://1193237596", "rbxassetid://1033173157", "rbxassetid://131237241", "rbxassetid://3064939784"}
local deathSounds = {"rbxassetid://2691819167", "rbxassetid://4494920504", "rbxassetid://481775819", "rbxassetid://566988981", "rbxassetid://856379539"}


function locateTorso(pos)
	local list = workspace:children()
	local torso = nil
	local dist = range
	local temp = nil
	local human2 = nil
	local temp2 = nil
	for x = 1, #list do
		temp2 = list[x]
		if (temp2.className == "Model") and (temp2 ~= script.Parent) then
			temp = temp2:findFirstChild("Torso")
			human2 = temp2:findFirstChild("Humanoid")
			if (temp ~= nil) and (human2 ~= nil) and (human2.Health > 0) then
				if (temp.Position - pos).magnitude < dist then
					torso = temp
					dist = (temp.Position - pos).magnitude
				end
			end
		end
	end
	return torso
end
while true do
	wait(0.1)
		local target = locateTorso(script.Parent.Torso.Position)
	if target ~= nil then
		human:MoveTo(target.Position, target)
	end
end


-- damage code that dosent work
function attack()
	local target = locateTorso(script.Parent.Torso.Position)        
	local human2 = target.Humanoid
	    if (human ~= nil) then
		if (torso.Position - target.Position).magnitude < 5 then
                human:TakeDamage(damage)
		        end
		wait(damageSpeed)
	end
end
