Hello, I have been working on a barrage system but I don't really know how to make the hitbox this is my current hitbox but its extremely lagy and destroys all fps

local function Detected(char)
	wait(.8)
	local hitbox = script.Meshes.HitBox:Clone()
	hitbox.CFrame = char.HumanoidRootPart.CFrame * CFrame.new(0,0,-2)
	hitbox.Parent = game.Workspace
	game.Debris:AddItem(hitbox,.08)


	local weld = Instance.new("ManualWeld")
	weld.Part0 = hitbox
	weld.Part1 = char.HumanoidRootPart
	weld.C0 = weld.Part0.CFrame:ToObjectSpace(weld.Part1.CFrame)
	weld.Parent = weld.Part0
	
	local connection 
	connection  = hitbox.Touched:Connect(function()end)	
	local results = hitbox:GetTouchingParts()
	
	coroutine.wrap(function()
		for i, obj in pairs(results) do
			if  not results[i]:IsDescendantOf(char)then
				local ehumanoid = results[i].Parent:FindFirstChild("Humanoid")
				local ehumanoidRP = results[i].Parent:FindFirstChild("HumanoidRootPart")
				if ehumanoid and ehumanoid.Health > 0 then
					hitbox:Destroy()

					if connection then
						connection:Disconnect()
					end
					
					local vel = Instance.new("BodyVelocity",ehumanoidRP)
					vel.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
					vel.Velocity = char.HumanoidRootPart.CFrame.lookVector * 4 + Vector3.new(0,.5,0)
					game.Debris:AddItem(vel, .5)

					ehumanoid:TakeDamage(2)
					break
				end
			end
		end
	end)()

	task.delay(.08,function()
		if connection then
			connection:Disconnect()
		end

	end)
