What do you need help with? V3

[prang123]

I'm making a token shop in TTT, and it's all working except one bit.
I'm trying to make it so I can set whether users can buy items or not using ply:CanBuy(), but it isn't working.
I've tried this to get the ply:CanBuy() working

function _R.Player:CanBuy( )
if !self:Alive() or self:Team() == TEAM_SPEC then
	return false
else
	return true
end

but I get this error when I try use it with the code below the error.
[QUOTE][ERROR] addons/tokenshop/lua/autorun/server/sv_cmds.lua:66: attempt to call method 'CanBuy' (a nil value)

concommand.Add("buyitem", function( p, c, a )
	if a[1] == NULL then return end
	local id = tonumber( a[1] )
	if !p:CanBuy() then p:ChatPrint("Please wait for the round to start before purchasing an item.") return end
	for k, v in pairs( Store.ItemsTable ) do
		if k == id then
			if p:GetTokens() >= v[2] then
				p:BuyItem( k )
				break
			else
				p:ChatPrint( "You dont have enough tokens to buy this!" )
			end
		end
	end
end

Any help would be much appreciated

how could i make it so?
hook.Add PlayerDeath than remove trail/smoke[/QUOTE]
OHH UMM YOU JUST SET IT TO NOT DRAW

[Kwaq]

i'll rephrase my question to make it less confusing

let's say i have a func_brush on the server, and when someone stands on it and jumps (OnEndTouch),
the server prints a message

it's possible right?

One way would be to check if players are standing on it, and pressing space, in a think hook. But that might be a bit messy. Another way is to loop through all the func_brushes on the map and remove them (once, when the map loads, of course), and spawn your own Lua entities in their place, which have an OnEndTouch function.

i tried that initially, but as you can see it removes the brushes (replacing with a model wouldn't work in this case)

if there were a way to keep the world geometry for an existing ent on a sent it would be great

I've made a custom weapon for my TTT server but the icon in the traitor shop and killed body isn't showing, it's still just a pink and black texture.

Where do I put the .vmt and .vtf files in the server files?

[QUOTE]-- Equipment menu information is only needed on the client
if CLIENT then
-- Path to the icon material
SWEP.Icon = "VGUI/ttt/icon_offisir_crossbow"

-- Text shown in the equip menu
SWEP.EquipMenuData = {
type = "Weapon",
desc = "Powerful silenced long range weapon. /n Only has one bolt. /n Unlimited purchases, 1 bolt per purchase."
};
end

-- Tell the server that it should download our icon to clients.
if SERVER then
-- It's important to give your icon a unique name. GMod does NOT check for
-- file differences, it only looks at the name. This means that if you have
-- an icon_ak47, and another server also has one, then players might see the
-- other server's dumb icon. Avoid this by using a unique name.
resource.AddFile("materials/VGUI/ttt/icon_offisir_crossbow.vmt")

I'm not a mapping person so I'm a little lost on what func_brush even does, but wouldn't it be easier to make an entity that does what you need? I did something similar before, created info_target entities on the map wherever I wanted my entity to be. Then when the game startd I just spawned the custom entity onto all of those info_target points. Gives you more flexibility with the entity and makes mapping less complex for people who want to help.

Bump. Still need help with this

Why do you have the [URL] tags there?

What if you create HtmlFrame.OpeningURL function before opening the url, does it even matter?

don't use _R, use a local variable whose value is set to FindMetaTable("Player"), then replace your _R.Player with that variable

Yes thank you for telling me what I am doing, but why is this error here? I don't understand how creating a vgui in PerformLayout then parenting it to that main vgui is bad. It works, how it should, although if you open the console you get all that garbage.

Not to mention it can't be done in init because the size of the panel is not ready at that time.

You're getting the MySQL has gone away error because you haven't communicated with the server for a time defined in wait_timeout. I simply made a timer which made a query every 30 seconds to avoid the MySQL server to go away.
I can't tell if that's the smartest solution but it solved the problem.

[pedrus]

Can someone tell me if it is possible to create a controllable NPC? And I mean as good as the player, with smooth and precise aiming and movement.

I need to know that before I go further into my gamemode. I plan to make the player control some NPCs and make them use custom weapons.
