Nameplates

[zork]

In case anyone is interested. I took p3lims advise and changed my script. I'm now checking for nameplates like this:

--init
  local _DB
  local a = CreateFrame("Frame")
  local index = 1
  --timer  
  local ag = a:CreateAnimationGroup()
  ag.anim = ag:CreateAnimation()
  ag.anim:SetDuration(0.33)
  ag:SetLooping("REPEAT")
  ag:SetScript("OnLoop", function(self, event, ...)
    if _DB.namePlateIndex and _G["NamePlate".._DB.namePlateIndex] then
      index = _DB.namePlateIndex
      _DB.namePlateIndex = nil
    end
    while(_G["NamePlate" .. index]) do
      local frame = _G['NamePlate' .. index]
      if frame and not frame.rDB_styled then
        styleNameplate(frame)
      end
      index = index + 1
    end
  end)
  ag:Play()
  --load some variable stuff
  a:RegisterEvent("PLAYER_LOGIN")
  a:RegisterEvent("PLAYER_LOGOUT")
  a:SetScript("OnEvent", function(self,event,...) 
    if event == "PLAYER_LOGIN" then
      _DB = _G["rDP_DB"] or {}
      _G["rDP_DB"] = _DB
    else
      _DB.namePlateIndex = index + 0
    end
  end)

Sidenote...the index must not be increased by 1 on logout or one nameplate will not get styled. (Because the index is already increased by 1 once an index is found.

Running perfectly for now:
