How do I make my gun FE Compatible?

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local tool = script.Parent
local handle = tool.Handle



function onClick()
	local gunharm = Instance.new("Part", workspace)
	gunharm.Anchored = true
	gunharm.BrickColor = BrickColor.new("CGA brown")
	gunharm.Material = Enum.Material.Neon
	gunharm.Orientation = handle.Orientation
	gunharm.Name = "gunharm"
	gunharm.Size = Vector3.new(1.16, 0.41, 1.13)
	gunharm.Position = game.Players.LocalPlayer:GetMouse().Hit.p
	handle.Sound:Play()
	gunharm.Touched:connect(function(hit)
		hit.Parent:FindFirstChild("Humanoid").Health = hit.Parent:FindFirstChild("Humanoid").Health - 30
	end)
	wait(0.0006)
	gunharm:Destroy()
end

game.ReplicatedStorage.compat1:FireServer(player, onClick)
script.Parent.Activated:Connect(onClick)

Please help me.
