Help with disabling VGUI DModelPanel when menu is open

[zarko]

I have created this VGUI :

        draw.RoundedBox(6, 10, ScrH()-150, 140, 140, Color(0,255,0,200))
        PlayerModel = vgui.Create("DModelPanel")
        function PlayerModel:LayoutEntity( Entity ) return end
        PlayerModel:SetModel( LocalPlayer():GetModel() )
        PlayerModel:SetPos(0, ScrH() - 190)
        PlayerModel:SetSize(150,175)
        PlayerModel:SetCamPos(Vector( 20, 0, 65 ))
        PlayerModel:SetLookAt(Vector( 5, 0, 63 ))
       
        timer.Create( "UpdatePlayerModel", 0.5, 0, function()
                if LocalPlayer():GetModel() != PlayerModel.Entity:GetModel() then
                        PlayerModel:Remove()
                        PlayerModel = vgui.Create("DModelPanel")
                        function PlayerModel:LayoutEntity( Entity ) return end         
                        PlayerModel:SetModel( LocalPlayer():GetModel())
                        PlayerModel:SetPos(5, ScrH() - 190)
                        PlayerModel:SetSize(152,170)
                        PlayerModel:SetCamPos(Vector( 20, 0, 65 ))
                        PlayerModel:SetLookAt(Vector( 0, 0, 63 ))
                end
        end)

How can I "disable" the vgui when the ESC menu is open?

1. To disable your stuff while menu is open, use gui.IsGameUIVisible()
2. Create your vgui elements out of the hudpaint hook, or you'll destroy memory
3. In your updateplayermodel timer, there's no need to recreate the element. just do PlayerModel:SetModel( LocalPlayer():GetModel() )

I'm really new to lua, i've tried to do this:

       		if gui.IsGameUIVisible() then
				PlayerModel:SetVisible(false)
				Avatar:SetVisible(false)
			else
				PlayerModel:SetVisible(true)
				Avatar:SetVisible(true)
			end

It still dosent work :\
did I do it wrong?
