AlertFrame identified by numbers?

I want to set the UIFrame alpha to 0 but still see the alert frames (e.g. from achievements or world quests). So I guess what I have to do is run SetIgnoreParentAlpha(true) on the respective frames. But what frames are these? When I use /fstack I get some strange names consisting of numbers. How could I handle this?

Frames that don't have a name or weren't created with the ParentKey XML attribute will have a random number in /fstack. This is basically their internal memory pointer similar to if you tostring() a table or function. There isn't a practical way to reference a frame with this number. It's mainly to show something's there and differentiate it from any other unnamed frame.

These are very likely created using frame pools and you'll need to look at the source code to find a way to get to them.

All right, thanks! I was afraid so... :-)

I already looked in the Blizzard code and found AlertFrameSystems.lua to be most promising.
It includes this function:

Code:

function WorldQuestCompleteAlertFrame_SetUp(frame, questData)

  PlaySound(SOUNDKIT.UI_WORLDQUEST_COMPLETE);



  frame.questID = questData.questID;

  frame.QuestName:SetText(questData.taskName);



  frame.QuestTexture:SetTexture(questData.icon);



  frame.ToastText:SetText(questData.displayAsObjective and TOAST_OBJECTIVE_COMPLETE or WORLD_QUEST_COMPLETE);



  ResetRewardFrames(frame);



  if questData.money > 0 then

    local rewardFrame = GetRewardFrame(frame, "WorldQuestFrameRewardTemplate");

    DungeonCompletionAlertFrameReward_SetRewardMoney(rewardFrame, questData.money);

  end



  if questData.xp > 0 and not IsPlayerAtEffectiveMaxLevel() then

    local rewardFrame = GetRewardFrame(frame, "WorldQuestFrameRewardTemplate");

    DungeonCompletionAlertFrameReward_SetRewardXP(rewardFrame, questData.xp);

  end



  if questData.currencyRewards then

    for currencyIndex, currencyTexture in ipairs(questData.currencyRewards) do

      local rewardFrame = GetRewardFrame(frame, "WorldQuestFrameRewardTemplate");

      SetPortraitToTexture(rewardFrame.texture, currencyTexture);

      rewardFrame.currencyIndex = currencyIndex;

    end

  end



  StandardRewardAlertFrame_AdjustRewardAnchors(frame);

end

So I tried to hook it:

Code:

hooksecurefunc("WorldQuestCompleteAlertFrame_SetUp", function(...)

  print("WorldQuestCompleteAlertFrame_SetUp", ...)

end)

But I never see the print of my hook...

Am I missing something?

That function runs before your code ever has a chance to hook it.

You need something like:

Lua Code:

local function SetIgnoreParentAlpha(_, frame)
    frame:SetIgnoreParentAlpha(true)
end
 
for _, subSystem in pairs(AlertFrame.alertFrameSubSystems) do
    local pool = type(subSystem) == 'table' and subSystem.alertFramePool
    if type(pool) == 'table' and type(pool.resetterFunc) == 'function' then
        hooksecurefunc(pool, "resetterFunc", SetIgnoreParentAlpha)
    end
end

Here is an easy way to test it:

Code:

/run UIParent:SetAlpha(0.5); NewMountAlertSystem:ShowAlert("123")

Wow, this is amazing!! How do you get to know stuff like this?? :-D

Could you also think of a way to SetIgnoreParentAlpha() of alert frames that are already shown; i.e. after the resetterFunc has already been fired?

Anyway, thank you so much!

UPDATE: I think I found a way.

Lua Code:

local collectedAlertFrames = {}
local alertFramesIgnoreParentAlpha = false
 
-- Function I call whenever I toggle UIParent's alpha. 
local function SetAlertFramesIgnoreParentAlpha(enable)
  alertFramesIgnoreParentAlpha = enable
  for _, v in pairs(collectedAlertFrames) do
    v:SetIgnoreParentAlpha(enable)
  end
end
 
local function CollectAlertFrame(_, frame)
  if not frame.IEF_collected then
    tinsert(collectedAlertFrames, frame)
    frame.IEF_collected = true
    frame:SetIgnoreParentAlpha(alertFramesIgnoreParentAlpha)
  end 
end
 
for _, subSystem in pairs(AlertFrame.alertFrameSubSystems) do
  local pool = type(subSystem) == 'table' and subSystem.alertFramePool
  if type(pool) == 'table' and type(pool.resetterFunc) == 'function' then
    hooksecurefunc(pool, "resetterFunc", CollectAlertFrame)
  end
end

That shouldn't be necessary since resetterFunc is called once when a new object is created or acquired from the pool and once when it is placed back in the pool (activeObjects and inactiveObjects respectively).

Yes, I don't want to interfere with other addons. So I only want the alerts to ignore parent UI when *my* addon fades out UIParent. But I got it to work. See my "UPDATE" in the previous post.
