I am trying to make a tool which when selected it shows a GUI which will be able to control a system I am developing.
Ok so: Put your GUI into StartGui and turn the frame's visibility to false. (Use a local script for this)
local gui = game.Players.LocalPlayer.PlayerGui:WaitForChild("YOUR SCREEN GUI NAME HERE",5).YOUR FRAME NAME HERE script.Parent.Equipped:Connect(function() gui.Visible = true end) script.Parent.Unequipped:Connect(function() gui.Visible = false end)
Script.Parent being inside the tool like here:https://gyazo.com/ebf795437d388fc492584cbadb632f57
