Showing specialization in portrait (using BGtargets)

[Malvesti]

Inspired by the great AJ sticky that puts class icons as portraits...

hooksecurefunc("UnitFramePortrait_Update",function(self)
        if self.portrait then
                if UnitIsPlayer(self.unit) then                         
                        local t = CLASS_ICON_TCOORDS[select(2, UnitClass(self.unit))]
                        if t then
                                self.portrait:SetTexture("Interface\\TargetingFrame\\UI-Classes-Circles")
                                self.portrait:SetTexCoord(unpack(t))
                        end
                else
                        self.portrait:SetTexCoord(0,1,0,1)
                end
        end
end)

... I'd like to do the same thing but for specs. I'm not the first person to ask this but I haven't found any answers.

I know the spec info is available to the UI, at least in BGs, from the BG targets addon. I have figured out a WA to do this...

function ()
    id = GetInspectSpecialization("target")
     _,name,_,_,_,_ = GetSpecializationInfoByID(id)
     if not name then name = "-" end
     return name
 end

... but there's a delay in changing targets before it snags the info. It would be great if there's a way to get this info locked down once the BG starts. Anyone have any thoughts or suggestions?

One idea would be to make a code snippet that can be pasted into BG Targets addon to piggyback on the spec data it's already collecting (and which is locked down once the BG begins).
http://www.curse.com/addons/wow/battlegroundtargets
That addon seems to store the spec info in the ENEMY_Data variable.

This code suggested by this post http://www.arenajunkies.com/topic/24...traits-script/

function Addon:PLAYER_TARGET_CHANGED()
  if not UnitExists("target") then return end -- We have no target

  local TargetArenaID
  for i = 1, 5 do -- Getting the ArenaID of the target
	if UnitIsUnit("target", "arena"..i) then
	  TargetArenaID = i
	  break
	end
  end
  if not TargetArenaID then return end -- Target is not a enemy player

  local IconPath = select(4, GetSpecializationInfoByID(GetArenaOpponentSpec(TargetArenaID)))
  SetPortraitToTexture(TargetFrame.portrait, IconPath)
end

It seems like it would be pretty simple to check if my target is one of the entities in ENEMY_Data, and if so then to set the portrait using the SetPortraitToTexture as shown. I'm just not exactly sure how to pull all of this together as a standalone snippet that could be pasted into BGtargets. Any help would be greatly appreciated.

I copied the arena part and added handling for battlegrounds. I tested it in an unrated battleground and it seems to work fine (arena and RBG are untested). You'll just have to make the code into an addon for yourself.

This replaces the icon of your targets portrait with the specialization icon of your target, when in arena or battleground:

local SpecTextures = {};

for i = 1, GetNumClasses() do
	local _, classTag, classID = GetClassInfo(i);

	SpecTextures[classTag] = {};

	for specID = 1, GetNumSpecializationsForClassID(classID) do
		local _, specName, _, specIcon = GetSpecializationInfoForClassID(classID,specID);

		SpecTextures[classTag][specName] = specIcon;
	end;
end;

local TargetFrameSpec = CreateFrame("Frame");
TargetFrameSpec:RegisterEvent("PLAYER_TARGET_CHANGED");
TargetFrameSpec:SetScript("OnEvent",function()
	if not UnitExists("target") then
		return;
	end;

	local _, instanceType = IsInInstance();

	if instanceType == "arena" then
		for i = 1, 5 do
			if UnitIsUnit("target","arena"..i) then
				local icon = (select(4,GetSpecializationInfoByID(GetArenaOpponentSpec(i))));
				if icon then
					SetPortraitToTexture(TargetFrame.portrait,icon);
					return;
				end;
			end;
		end;
	elseif instanceType == "pvp" then
		for scoreIndex = 1, GetNumBattlefieldScores() do
			local name, _, _, _, _, _, _, _, classTag, _, _, _, _, _, _, specName = GetBattlefieldScore(scoreIndex);
			if GetUnitName("target",true) == name then
				local icon = SpecTextures[classTag][specName];
				
				if icon then
					SetPortraitToTexture(TargetFrame.portrait,icon);
					return;
				end;
			end;
		end;
	end;
end);

Seems to work perfectly. Thanks so much!!
