[Arthur_Batalha (rthuur)]

Hello everyone! So, i have a script and i’m trying to apply an tag system in it, like on the linked sword one, the problem is that im am stooped and don’t now how to do it:

mah script:

--Variables.
	local Tool = script.Parent.Parent
	local Handle = Tool:WaitForChild("Handle")
--
	local ItemStatus = script.Parent:WaitForChild("ItemStatus")
	local ItemStatusModule = require(ItemStatus)
--
	local EnemyHumanoid = ItemStatusModule.ItemStatus.HumanoidToDamage
	local SwordDamage = ItemStatusModule.ItemStatus.Damage
	local SwordCooldown = ItemStatusModule.ItemStatus.Cooldown
--
	local Trail = Handle:WaitForChild("Trail")
	Trail.Lifetime = SwordCooldown
--
	local IsAttacking = false
	local Debounce = false
--

--Functions.
	Tool.Activated:Connect(function()
		if IsAttacking == false then
			IsAttacking = true
			task.wait(SwordCooldown)
			IsAttacking = false
			Debounce = false
		end
	end)
--
	Handle.Touched:Connect(function(Hit)
		
		--DamageFunction
			if IsAttacking == true and Hit.Parent:WaitForChild(EnemyHumanoid):IsA("Humanoid") then
				if Debounce == false then
				Debounce = true
				Hit.Parent:FindFirstChild(EnemyHumanoid):TakeDamage(SwordDamage)
				task.wait(SwordCooldown)
				Debounce = false
				end
			else
				return
			end
		--
	end)
