Keybind Aiming Script Fix

I don’t know how to word the title, but basically, I have this script that when I press F, it changes the field of view. I used this to make a primitive aim down sights system. I need help because I don’t know how to make it do the unaim lines of code when I press F again. Here’s my code:

‘’'Lua
–local scoped = false
local cam

script.Parent.Equipped:connect(function(mouse)
cam = game.Workspace.CurrentCamera
mouse.KeyDown:connect(function(key)
key = key:lower()

	if key == "f" then
		cam.FieldOfView = scoped and 70 or 51
		scoped = not scoped

		script.Parent.ADSGun.Transparency = 0
		script.Parent.ADSSight1.Transparency = 0
		script.Parent.ADSSight2.Transparency = 0
		script.Parent.ADSSight3.Transparency = 0
		script.Parent.FrontSight1.Transparency = 0
		script.Parent.FrontSight2.Transparency = 0
		script.Parent.FrontSight3.Transparency = 0
		script.Parent.FrontSight4.Transparency = 0
		script.Parent.FrontSight5.Transparency = 0
		script.Parent.FrontSight6.Transparency = 0
		
		script.Parent.WorldGun.Transparency = 1
		script.Parent.WorldBackSight.Transparency = 1
		script.Parent.FakeMag.Transparency = 1
		script.Parent.AttachmentRail1.Transparency = 1
		script.Parent.AttachmentRail2.Transparency = 1
		script.Parent.WorldSight5.Transparency = 1
		script.Parent.WorldSight4.Transparency = 1
		script.Parent.WorldSight3.Transparency = 1
		script.Parent.WorldSight2.Transparency = 1
		script.Parent.WorldSight1.Transparency = 1
		end
end)

end)

script.Parent.Unequipped:connect(function()
cam.FieldOfView = 70
script.Parent.ADSGun.Transparency = 1
script.Parent.ADSSight1.Transparency = 1
script.Parent.ADSSight2.Transparency = 1
script.Parent.ADSSight3.Transparency = 1
script.Parent.FrontSight1.Transparency = 1
script.Parent.FrontSight2.Transparency = 1
script.Parent.FrontSight3.Transparency = 1
script.Parent.FrontSight4.Transparency = 1
script.Parent.FrontSight5.Transparency = 1
script.Parent.FrontSight6.Transparency = 1

script.Parent.WorldGun.Transparency = 0
script.Parent.WorldBackSight.Transparency = 0
script.Parent.FakeMag.Transparency = 0
script.Parent.AttachmentRail1.Transparency = 0
script.Parent.AttachmentRail2.Transparency = 0
script.Parent.WorldSight5.Transparency = 0
script.Parent.WorldSight4.Transparency = 0
script.Parent.WorldSight3.Transparency = 0
script.Parent.WorldSight2.Transparency = 0
script.Parent.WorldSight1.Transparency = 0

end)

The code starting from:

script.Parent.Unequipped:connect(function()
cam.FieldOfView = 70

is where I’m trying to make it do if it presses F again.

local uis = game:GetService("UserInputService") -- mouse.keydown is deprecated so you need userinputservice to check player inputs in the future
local cam = workspace.CurrentCamera 
local scoped = false
script.Parent.Equipped:Connect(function()
	uis.InputBegan:Connect(function(input,gpe)
		if gpe then return end -- just make sure if you are chatting and pressing f the function should not run
		if input.KeyCode == Enum.KeyCode.F then
			scoped = not scoped
			cam.FieldOfView = scoped and 70 or 50
			script.Parent.ADSGun.Transparency = 0
			script.Parent.ADSSight1.Transparency = 0
			script.Parent.ADSSight2.Transparency = 0
			script.Parent.ADSSight3.Transparency = 0
			script.Parent.FrontSight1.Transparency = 0
			script.Parent.FrontSight2.Transparency = 0
			script.Parent.FrontSight3.Transparency = 0
			script.Parent.FrontSight4.Transparency = 0
			script.Parent.FrontSight5.Transparency = 0
			script.Parent.FrontSight6.Transparency = 0

			script.Parent.WorldGun.Transparency = 1
			script.Parent.WorldBackSight.Transparency = 1
			script.Parent.FakeMag.Transparency = 1
			script.Parent.AttachmentRail1.Transparency = 1
			script.Parent.AttachmentRail2.Transparency = 1
			script.Parent.WorldSight5.Transparency = 1
			script.Parent.WorldSight4.Transparency = 1
			script.Parent.WorldSight3.Transparency = 1
			script.Parent.WorldSight2.Transparency = 1
			script.Parent.WorldSight1.Transparency = 1
		end
	end)
end)
