当Roblox中没有配备工具时,如何使Gui不可惩罚?

我有一个脚本,可以在Roblox中右键单击时打开枪的范围,但即使在没有右键单击的情况下也会打开,我不知道如何做到这一点。

脚本:

local player = game.Players.LocalPlayer
local tool ,equipped= script.Parent,false
local uis = game:GetService("UserInputService")
local Ui = script:WaitForChild("ScopeGui")

script.Parent.Unequipped:Connect(function()
    game.Players.LocalPlayer.PlayerGui:FindFirstChild(Ui.Name):Destroy()
end)

tool.Equipped:Connect(function()equipped=true;end)
tool.Unequipped:Connect(function()equipped=false;end)
uis.InputBegan:Connect(function(input)if not equipped then return end

end)    

    uis.InputBegan:Connect(function(input, typing)

    if input.UserInputType == Enum.UserInputType.MouseButton2 then
        game.Players.LocalPlayer.PlayerGui.ScopeGui.ScopeLbl.Visible = true
        workspace.Camera.FieldOfView = 23.5
        player.CameraMode = Enum.CameraMode.LockFirstPerson
    end
end)

uis.InputEnded:Connect(function(input, typing)

    if input.UserInputType == Enum.UserInputType.MouseButton2 then
        game.Players.LocalPlayer.PlayerGui.ScopeGui.ScopeLbl.Visible = false
        wait()
        workspace.Camera.FieldOfView = 70
        wait()
        player.CameraMode = Enum.CameraMode.Classic
        player.CameraMaxZoomDistance=25
        player.CameraMinZoomDistance=7
        end
end)
wait(1)
player.CameraMode = Enum.CameraMode.Classic
player.CameraMinZoomDistance = 0
player.CameraMaxZoomDistance = 25```
