How to make a double click for a tool?

Sorry I cant really explain This but i found out this method on accident hopefully the script is easy to understand, so place a local script in starter gui/starter pack, the script mostly consists of variables so it shouldnt be hard to understand the script:

local player = game.Players.LocalPlayer
   local mouse = player:GetMouse()

local B1 = false
 
  local doubleclicked = false
   
     local B2 = false

 local NEXTB = false

mouse.Button1Down:Connect(function()
	if NEXTB == false then
		B1 = true
	wait(0.1)
	B1	= false
	  NEXTB = true
	print("CMON")
	wait(0.05)-- how long you want the script to wait before clicking the button again and defining it as a double click,
	 NEXTB = false
	print("Aww no double click")
	
	end

end)
mouse.Button1Down:Connect(function()
 if NEXTB == true then
	   doubleclicked = true 
	wait(0.1)
	doubleclicked = false
	-- your function
			print("Player Has Double Clicked")
		end
end)
