I want to make a gun and bypass a tool, but I'm having debounce problems? [Figured it out myself]

So as I described in the title, the gun is fully functional, but when you double(or more) click and hold it's like it's running multiple threads. I've tried adding debounces but I'm still puzzled. The problem is at the mouse.Button1down function (at the bottom). Let me know you if have any alternate ways of scripting this. Thanks :)

function fire()
--Cloning stuff, direction ETC, everything's working here
end

local button1down = false

function Active()
while button1down == true do
	local player = game.Players.LocalPlayer
	local humanoid = player.Character.Humanoid
		if humanoid == nil then
			print("Humanoid not found")
			return
		end
	local player = game.Players.LocalPlayer
	local mouse = player:GetMouse()
	wait(.3)
	fire()
end
end
	
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

local mouse = game.Players.LocalPlayer:GetMouse()
	mouse.Button1Down:connect(function()
   		button1down = true
		Active()
	end)

	mouse.Button1Up:connect(function()
    	button1down = false
print('off')
	end)

That is NOT a debounce, that is a variable that poorly connect/disconnects a function, also, you should not use a while loop

var = nil
current = tick() --Set up the loop, tick() sends the time
function active()
	if current - tick() < .3 then return end
	current = tick() --Reset the position of "current"
	--stuff
end)
push:connect(function()
	var = game:GetService('RunService').Stepped:connect(Active)
	--hold the connection in a variable, like you do in Clone()
end)
release:connect(function()
	if var then var:disconnect() end --INSTANTLY DISCONNECTS
	-- "if bool then" is equal to "if bool == true then"
	-- "if object then" is equal to "if object ~= nil then"
	--"if string then" does not exist
end)

What's happening is that during the wait() is that if the variable is changed, it cannot check it because it only checks at the end of the loop function. However if you disconnect, the function will disconnect the function from the loop.
