How to open/close GUI?

Help and Feedback Scripting Support
#1

hey everyone, so I’m trying to make a GUI that opens/closes when the player pushes “F”,
but don’t really know how to use ContextActionService. Solutions?

local CAS = game:GetService("ContextActionService")
local inventory = script.Parent

local function inventoryOpen()
	inventory.Visible = true
end

local function inventoryClose()
	inventory.Visible = false
end

while true do wait(.1)
	if inventory.Active == false then
		CAS:BindAction("inventoryActivate", inventoryOpen, false, Enum.KeyCode.F)
	elseif inventory.Active == true then
		CAS:BindAction("inventoryDeactivate", inventoryClose, false, Enum.KeyCode.F)
	else
		warn("Error")
	end
end
#2 
local player = game.Players.LocalPlayer
local UIS = game:GetService("UserInputService")
		
UIS.InputBegan:Connect(function(input,gameProcessedEvent)
	if gameProcessedEvent then return end
	if input.UserInputType == Enum.UserInputType.Keyboard then
		if input.KeyCode  == Enum.KeyCode.F then
			player.PlayerGui.OpenclosingGui.Frame.Visible = not player.PlayerGui.OpenclosingGui.Frame.Visible
	   	end
	end
end)

Binding the keys every .1 seconds isn’t how you use BindAction

Instead just do

CAS:BindAction("inventoryDeactivate", inventoryClose, false, Enum.KeyCode.F)
CAS:BindAction("inventoryActivate", inventoryOpen, false, Enum.KeyCode.F)

at the bottom of your script
