self.bugged

Hi all,

I am new to this oUF thing and need your help on this matter. I am trying to store a variable in self and to change it using PostUpdateHealth. But for some reason, I cant seem to make it work. Pls look at codes below:

--[[my postupdatehealth]]--

local PostUpdateHealth = function(Health, unit, min, max)
  local self = Health:GetParent()
  self.Ptext:SetText("b") -- <----self.Ptext is always nil ???????
end

--[[ init is called for every unit frame ]]--

local function init(self)
	self:RegisterForClicks('AnyUp')
	self:SetScript('OnEnter', UnitFrame_OnEnter)
	self:SetScript('OnLeave', UnitFrame_OnLeave)

	local Ptext = self:CreateFontString(nil,"OVERLAY")
	Ptext:SetFont( "Interface\\AddOns\\oUF_HL2\\ghostsmileys.ttf", 72, "OUTLINE")
	Ptext:SetTextColor(0.81, 0.86, 0.77)
	Ptext:SetText("a")
	self.Ptext = Ptext -- <---trying to store self.Ptext here.

end

--[[ target frame ]]--

local function CreateTarget(self)
   init(self) --
   --[[ omit codes to create Health.... etc]]
   self.Ptext:SetPoint("CENTER",self,"CENTER") -- <---self.Ptext is ok here 
   self.Health = Health
   self.Health.PostUpdate = PostUpdateHealth
end

I am getting an error saying self.Ptext is undefined. What do I miss? Do I need to change PostUpdateHealth() also to make it work?

I assume you have something else as parent for Health. You could always access it through Health.__owner, which is set when the health element is enabled for the unit frame.

This. Check your self.Health creation. Maybe your parent is not set to self.

local Health = CreateFrame("StatusBar", nil, self)
self.Health = Health

Thank you Haste and Zork. You guys are both right. Indeed something else was the parent of Health.

Old codes

 local Health = CreateFrame("StatusBar",nil,Hbg)

New codes <---which fixes the problem

local Health = CreateFrame("StatusBar",nil, self)

Thank you guys.
