Help with Dlabel.

[killerrichard]

Hello,

I need your help, i have a error when i open my help menu .

The error is : [@lua\vgui\dcategorycollapse.lua:83] bad argument #1 to 'SetText' (string expected, got nil)

The Function is :

local function AddText ( Text, Owner )
	local CategoryContentOne = vgui.Create("DLabel")
	CategoryContentOne:SetText( Text )
	CategoryContentOne:SizeToContents()
	Owner:AddItem(CategoryContentOne)
end

A example : AddText('Question about the gamemode ?', PanelList1);

Thanks.

Figured it has nothing todo with your function actually, seems like you tried to call SetLabel on the collapsable without passing a string.

[killerrichard]

Sorry but it worked before the update of gmod :s

Edit : A example to fix this please ?

[Wizard of Ass]

Please post the whole file.

CollapsibleCat:SetLabel(v.Name)

v.Name is nil, go check for that.

[killerrichard]

Ok Thanks i test this .

[FlapadarV2]

Just a little tip, you can get the "alphabet weight" by doing this

string.byte(char:upper())-65

[killerrichard]

Thanks Flap :D You are a king in lua lol ^^

[editline]10th June 2011[/editline]

Ok i have fixed thanks all of the topics .

and now i have a error with a lua ^^

The lua is :

 function ENT:Use ( Activator, Player)
	if !Player or !Player:IsValid() or !Player:IsPlayer() then return false; end
	
	if Player:Team() != TEAM_CITIZEN then
		Player:Notify('Government official cannot use this machine.');
		return false;
	end
	
	if self.Spinning then return false; end
	if Player:GetCash() < 15 then Player:Notify('Not enough cash.'); return false; end
	
	Player:AddProgress(28, 1);
	
	Player:TakeCash(15);
	
	self.Spinning = true;
	self.Player = Player;
	
	for i = 1, 3 do
		self.Wheels[i].StopTime = CurTime() + SpinTimes[i];
		self.Wheels[i].Outcome = ChancesTable[math.random(1, #ChancesTable)];
		self.Wheels[i].StopSpinning = true;
	end
	
	local RP = RecipientFilter();
	RP:AddPVS(Player);
	RP:AddPlayer(Player);
	
	umsg.Start('rp_slots_rotate', RP);
		umsg.Entity(self);
		
		for i = 1, 3 do
			umsg.Short(self.Wheels[i].Outcome);
		end
		
	umsg.End();


function ENT:AnnounceResults ( )
	local AmmountWon = 0;
	
	if self.Wheels[1].Outcome == self.Wheels[2].Outcome and self.Wheels[1].Outcome == self.Wheels[3].Outcome then
		AmmountWon = CashWonTable[self.Wheels[1].Outcome];
	end
	
	if AmmountWon != 0 then
		self.Player:GiveCash(AmmountWon);
	end
		
	for i = 1, 3 do
		self.Wheels[i].StopTime = nil;
		self.Wheels[i].Outcome = nil;
		self.Wheels[i].StopSpinning = nil;
	end
	
	self.Spinning = nil;
	self.Player = nil;
end
 
 
function ENT:Think() 

	if self.Spinning then
		if self.Wheels[3].StopTime and CurTime() >= self.Wheels[3].StopTime then
			self:AnnounceResults();
		end
	end
		
	self:NextThink(CurTime() + .01);
	return true
end

The error is on this :

	local RP = RecipientFilter();
	RP:AddPVS(Player);
	RP:AddPlayer(Player);

It helps if you use [noparse][lua][/lua] instead of

[/noparse] the lua tags add some syntax highlighting and line numbers, it help to identify problems. When you have an error please post the error code too, it helps a lot., I believe Player is a reserved word, try changing all the Player to ply in the ENT:Use function.
