Wtf is wrong?

[SebSharpy]

You need to create the vgui clientside.

[JSharpe]

Are you sure the vgui/visuals are only being called on the client?

If you run a script like that through shared or Server side vgui does not exist.

What SebSharpy said...

[Tokiz]

Ehhm, and how do i creat the client side thing? Could anyone send the code and tell me where i shold put it?

[JSharpe]

Guessing you script is being run shared. All that it should require is for you to place
[lua]if (CLIENT) then
--vgui.Create( "things_here" )
end
[/lua]

[Tokiz]

Right?

ITEM.Name = "Propaganda";
ITEM.Class = "propaganda";
ITEM.Description = "Propaganda from Resistances";
ITEM.Model = "models/props_junk/garbage_newspaper001a.mdl";
ITEM.Purchaseable = true;
ITEM.Price = 1;
ITEM.ItemGroup = 1;

function ITEM:Drop(ply)

end

function ITEM:Pickup(ply)

self:Remove();

end

function ITEM:UseItem(ply)

if (CLIENT) then
HTMLTest = vgui.Create("HTML")
HTMLTest:SetPos(50,50)
HTMLTest:SetSize(ScrW() - 100, ScrH() - 100)
HTMLTest:OpenURL("http://www.garrysmod.com")
end

end

Okey, it works no errors. but no Windows open. Nothihing happens.

[Lexic]

That's because ITEM:UseItem is called on the server, and the server only.

[JSharpe]

[QUOTE=Lexic;17493536]That's because ITEM:UseItem is called on the server, and the server only.[/QUOTE]

Because of this, you would ([i]recommended[/i]) use a [b][url=http://wiki.garrysmod.com/?title=User_Messages]user message[/url][/b] from the server to the client, to tell the client to open it.
The wiki link provided should help you through the process.

The clientside code can be placed anywhere that is included by cl_init.lua

[QUOTE=Crazy Quebec;17495530]The clientside code can be placed anywhere that is included by cl_init.lua[/QUOTE]

Picking away at nothing here, but you don't specifically need to include things in cl_init. You can include files in separate scripts or even SendLua it.

[Tokiz]

ehm, now don't understand a shit xD

Okey, shold i add:

function my_message_hook( um )
Msg( "The text is " .. um:ReadString() .. "\n" )
Msg( "The number is " .. um:ReadLong() .. "\n" )
Msg( "The entity " .. tostring( um:ReadEntity() ) .. "\n" )
end
usermessage.Hook("my_message", my_message_hook)

In the item lua file.

and add

local rp = RecipientFilter() -- Grab a CRecipientFilter object
rp:AddAllPlayers() -- Send to all players!

umsg.Start("my_message", rp)
umsg.String( "Hello World! The answer to everything is")
umsg.Long( 42 )
umsg.Entity( ents.FindByClass("prop_physics")[1] )
umsg.End()

in another file in the gamemode?

[Crazy Quebec]

No, it's the other way around and obviously you'd change it to your needs.

You should also learn of instances.
[url]http://wiki.garrysmod.com/?title=Client-Server_relationship_in_Lua[/url]

Basically the item is on the machine running the server, when it's used it will then send a message to the client's machine( with the usermessages ). The user's machine (the client) will read it and react on it. If you order the server itself to open a window it won't really do much, that kind of stuff has to be done per user on their machines.

[Tokiz]

um, Could you PLEASE Help me with this? I don't understand so much now.

Could you post the code/codes in pasterbin ?

[Dlaor]

Try this.
[lua]ITEM.Name = "Propaganda";
ITEM.Class = "propaganda";
ITEM.Description = "Propaganda from Resistances";
ITEM.Model = "models/props_junk/garbage_newspaper001a.mdl";
ITEM.Purchaseable = true;
ITEM.Price = 1;
ITEM.ItemGroup = 1;

function ITEM:Drop(ply)

end

function ITEM:Pickup(ply)

self:Remove();

end

function ITEM:UseItem(ply)

ply:SendLua( [[HTMLTest = vgui.Create("HTML")
HTMLTest:SetPos(50,50)
HTMLTest:SetSize(ScrW() - 100, ScrH() - 100)
HTMLTest:OpenURL("http://www.garrysmod.com")]] )

end[/lua]
It's a shitty way of doing it, but I'm too lazy to use usermessages at the moment.

THX! It Works! :D But i got another problem now. I need a Close button so pp can close the window. also maybe if its possible. title.

[Jamie Sharpe]

Some thing along the lines of:

[lua]
local closeButton = vgui.Create("DButton")
closeButton:SetPos( 20, 20 )
closeButton:SetText( "Close" )
closeButton.DoClick = function()
HTMLTest:Remove()
closeButton:Remove()
end
[/lua]
:raise:

Didn't work, No close button.

Why not use a usermessage?

Place this in cl_init.lua
[lua]function htmlthing()

HTMLTest = vgui.Create("HTML")
HTMLTest:SetPos(50,50)
HTMLTest:SetSize(ScrW() - 100, ScrH() - 100)
HTMLTest:OpenURL("http://www.garrysmod.com")

local closeButton = vgui.Create( "DButton", HTMLTest ) --parent it to the frame
closeButton:SetPos( 20, 20 ) -- I don't know the exact position but watev, if this doesn't appear, try doing to values your self.
closeButton:SetText( "Close" )
closeButton.DoClick = function()

HTMLTest:Remove()
closeButton:Remove()

end

end
usermessage.Hook( "HTML", htmlthing )[/lua]

in the function ITEM:UseItem(ply) do

[lua]
umsg.Start( "HTML", ply ) umsg.End() [/lua]

You did the close button again on serverside, that is why you're getting that error, anything VGUI should be done clientside( cl_init or what ever ).
