Game is spewing out multiple derma menus and other issues.

[bran92don]

I am trying to code something, that ask for the users input when they press use on the entity. Whenever I use the entity though, it makes like 50 copies of the menu on my screen.

Here is the code:

function ENT:Use( activator, caller )


	if ( activator:IsPlayer() ) then
	
	if SERVER then
		umsg.Start( "opendatgame", activator )
		umsg.End()
	end
	
	end
	end

if CLIENT then


function opendatgame()
			local base = vgui.Create( "DFrame" )
			
			base:SetSize( 500,500 )
			base:Center()
			base:SetSizable( true )
			base:SetVisible( true )
			base:SetTitle( "Picture" )
			base:SetDraggable( true )
			base:ShowCloseButton( true )
			base:MakePopup()
			base.Paint = function()
				draw.RoundedBox( 8, 0, 0, base:GetWide(), base:GetTall(), Color(35,35,35,200))
				draw.DrawText( "Please enter the URL", "TargetID", base:GetWide()/2, 50, Color( 255,255,255,255 ), TEXT_ALIGN_CENTER )
			end
			
			
			local DermaText = vgui.Create( "DTextEntry", base )
	DermaText:SetPos( 20,25 )
	DermaText:SetTall( 20 )
	DermaText:SetWide( 450 )
	DermaText:SetEnterAllowed( true )
	DermaText.OnEnter = function()
		url=DermaText:GetValue()
		base:Close()
    base:SetVisible( false )
end
end
usermessage.Hook( "opendatgame", opendatgame )
end

I am thinking that it is because I am hosting the serer on my computer, but It has never done that before when I have coded stuff this way.

Issue 2:

The ent I am working on keeps spewing out these errors:

[ERROR] addons/test small/lua/entities/picture.lua:164: attempt to index global 'vgui' (a nil value)

I looked at the first error and was like, "Oh I should just put that in a client if statement since you can't runt hat stuff on the server side.". Well as soon as I did that it shoots out this massive amount of spam on my console:

Thanks now just to fix the other issue.

[Rubat]

The other issue is that you are trying to create the panels on server, which is impossible. Use "if CLIENT then /*createpanels*/ end" construction.

[QUOTE=Robotboy655;42817425]The other issue is that you are trying to create the panels on server, which is impossible. Use "if CLIENT then /*createpanels*/ end" construction.[/QUOTE]

I did try that, I mentioned me doing that in the original post. That is why I am confuzzled with the error I am getting.

After I add the if client statement, it spams this:

(a nil value)addons/test small/lua/entities/picture.lua:178: attempt to index global 'browser' 

The thing is browser is a local function not global.

Also I have noticed that it does not change depending on the user, it keeps the same image for every user whenever someone changes it.

I was experimenting a lot in this, so sorry if that gets confusing. My code is normally more organized then that and has a ton of comments in it.

[Rubat]

What line errors?

[bran92don]

Before the function drawsign (), if I put a if client statement there it will spaz out and keep generating a error until it crashes my game. The error it produces says it is on line 178.

[dingusnin]

The vgui element HTML does not exist. Use DHTML.

[bran92don]

[QUOTE=dingusnin;42831779]The vgui element HTML does not exist. Use DHTML.[/QUOTE]

Thanks that solved one issue.

It seems like every time I try and finish this some error arises.

I was trying to make it change the picture depending on the entity, but if one person changes the picture it changes every single picture on the map.

I moved my variables to the initialize area to make it dependent on the entity but that did not fix anything.

[Rubat]

Assing your variables to ENT table like ENT.url = "test" and self.url="test" inside ENT:Whatever function.
