Open derma on key

[Flaow]

I've already manage to bind the derma panel to a key however when I hit it, it opens like 10 dermas on eachother.
If anyone could help me with how to make it so that it only opens one

function ActMenu()
local Frame = vgui.Create( "DFrame" )
Frame:SetSize( 328, 101 )
Frame:Center()
Frame:SetTitle("")
Frame:MakePopup()
Frame:SetVisible(true)
Frame:ShowCloseButton(false)
Frame.Paint = function( self, w, h ) 
	draw.RoundedBox( 0, 0, 0, w, h, Color( 30, 30, 30, 220 ) )
end
end
hook.Add( "ActMenuShow", "ActMenuShow", ActMenu )
hook.Add( "Think", "MenuKeyListener", function()
    if ( input.IsKeyDown( KEY_G ) ) then
        ActMenu()
    end
end )

If possible I would even like to do it so that it is only open whilst you hold the key and when you release it it disappears

local f1pressed = false

hook.Add("Think", "input_menukey", function()
	if input.IsKeyDown(KEY_F1) and not f1pressed then
		f1pressed = true -- When F1 is pressed
		ToggleMenu() -- I toggle my menu here but you may want to do something like ActMenu() instead
	elseif (not input.IsKeyDown(KEY_F1)) and f1pressed then
		f1pressed = false -- When F1 is released
                -- And close your menu here
	end
end)

This is what I use for my gamemode's options menu. Works perfectly.

Hopefully it helps.

local keyDown;

hook.Add("Think", "", function()
	if (input.IsButtonDown(KEY_G) and !keyDown) then
		ActMenu();
	end
	
	keyDown = input.IsButtonDown(KEY_G);
end);

This is my way of doing it.

How would I close the menu from outside the ActMenu() function?

Make the frame variable OUTSIDE the function:

local Frame
function ActMenu()
Frame = vgui.Create( "DFrame" )
// the rest of the code

Then just do Frame:Remove()

[Moosicorn]

local Frame
local keyDown

function ActMenu()
	if (Frame) then
		Frame:Remove()
		Frame = nil
	else
		Frame = vgui.Create( "DFrame" )
		Frame:SetSize( 328, 101 )
		Frame:Center()
		Frame:SetTitle("")
		Frame:MakePopup()
		Frame:SetVisible(true)
		Frame:ShowCloseButton(false)
		
		Frame.Paint = function( self, w, h ) 
			draw.RoundedBox( 0, 0, 0, w, h, Color( 30, 30, 30, 220 ) )

	end

That works great but I'm trying to get the hold down

Tried that but when I used my buttons that I have on the derma on their DoClick I have 1 command and then Frame:Close() and it does an error

[QUOTE=Moat;51300824]Since the think hook is called every frame, you're gonna need to add a simple timer check to prevent the menu from opening every frame while the key is pressed.

Example:
[lua]
local key_down_timer = CurTime()

local key_down_delay = 1

hook.Add( "Think", "iskeydown_example", function()

if ( input.IsKeyDown( KEY_G ) and key_down_timer <= CurTime() ) then

-- Open your derma here

key_down_timer = CurTime() + key_down_delay -- reset the timer

end

end )
[/lua][/QUOTE]

I'm using this, it works perfectly. How would I make it so that when the menu is open already it doesn't open a new one when I click it again?

I would like to use this but don't know how to

Misread the question, thought you wanted a toggle.

local Frame

function ActMenu()
	if (Frame and !input.IsButtonDown(KEY_G)) then
		Frame:Remove()
		Frame = nil
	elseif (input.IsButtonDown(KEY_G) and !Frame) then
		Frame = vgui.Create( "DFrame" )
		Frame:SetSize( 328, 101 )
		Frame:Center()
		Frame:SetTitle("")
		Frame:MakePopup()
		Frame:SetVisible(true)
		Frame:ShowCloseButton(false)
		
		Frame.Paint = function( self, w, h ) 
			draw.RoundedBox( 0, 0, 0, w, h, Color( 30, 30, 30, 220 ) )
		end
	end
end

hook.Add("Think", "MenuKeyListener", function()
	ActMenu()
end);

Opens up multiple menus and they aren't hold down only and it makes the buttons on it do this error [ERROR] lua/derma.lua:29: attempt to index upvalue 'Frame' (a nil value)
