HasArtifactEquipped() not trigger on PLAYER_ENTERING_WORLD

Hi all,

I have coded to show in a LDB the artifact power instead the max level to accomplish this:
http://www.wowinterface.com/download....html#comments

Lua Code:

local frame = CreateFrame("Frame")
frame:RegisterEvent("PLAYER_ENTERING_WORLD")
frame:RegisterEvent("PLAYER_XP_UPDATE")
frame:RegisterEvent("ARTIFACT_XP_UPDATE")
-- frame:RegisterEvent("PLAYER_EQUIPMENT_CHANGED")
 
frame:SetScript("OnEvent", function(self, event, ...)
 
    if UnitLevel("player") == GetMaxPlayerLevel() then 
    
        if HasArtifactEquipped() then 
        
            local ArtPower, ArtPointsSpent= select(5,C_ArtifactUI.GetEquippedArtifactInfo());
            dataobj.text = string_format("A:%s %.1f%%", ArtPointsSpent, ArtPower/C_ArtifactUI.GetCostForPointAtRank(ArtPointsSpent)*100)
    
        else 
            
            dataobj.text = "L: " .. UnitLevel("player")     
 
        end
    
    else    
    
        dataobj.text = string_format("L:%s %.1f%%", UnitLevel("player"), UnitXP("player")/UnitXPMax("player")*100)
    
    end
    
end)

The problem is that if I don't use the:

Lua Code:

frame:RegisterEvent("PLAYER_EQUIPMENT_CHANGED")

on the first login it doesn't trigger

Lua Code:

HasArtifactEquipped()

and so show only the level 110 info.

If I do /reload everything is fine ...

If I register also PLAYER_EQUIPMENT_CHANGED it works but I like to not add unnecessary events.

So the question is :) ...
Is possible that on PLAYER_ENTERING_WORLD I don't have yet the information about the equipped items ?
Is there a more specific event than PLAYER_EQUIPMENT_CHANGED that I can register to check this ?

Thanks to you all for the always precious help.

PLAYER_EQUIPMENT_CHANGED is not an unnecessary event and you should use it to detect weapon swaps (which also happen when the player changes specializations and the game swaps the equipped artifact automatically).

The event at which equipped artifact data becomes initially available is UNIT_INVENTORY_CHANGED.

The artifact data from what I can tell doesn't fire at login which is why I ended up using a timer and forcing a function call.

ie:

Code:

local events_a = CreateFrame("Frame")

events_a:RegisterEvent("ARTIFACT_XP_UPDATE")

events_a:RegisterEvent("PLAYER_ENTERING_WORLD")

events_a:RegisterEvent("UNIT_INVENTORY_CHANGED")

events_a:SetScript("OnEvent", ArtifactBar_Update)

C_Timer.After(3, ArtifactBar_Update)

I'm just doing it like this.

Code:

-- get artifact power data

function afbar:ARTIFACT_XP_UPDATE()

        local hasArtifact = HasArtifactEquipped("player")

        if hasArtifact then

                local _, _, _, _, totalXP, pointsSpent = C_ArtifactUI.GetEquippedArtifactInfo()

                local numPoints, artifactXP, xpForNextPoint = MainMenuBar_GetNumArtifactTraitsPurchasableFromXP(pointsSpent, totalXP)

                afbar:SetMinMaxValues(0, xpForNextPoint)

                afbar:SetValue(artifactXP)

                afbar:SetAlpha(0.4)

                xptext:SetFormattedText("%d / %d (%.0f%%)", artifactXP, xpForNextPoint, artifactXP/xpForNextPoint*100)

        else

                afbar:SetAlpha(0)

        end

end

afbar.PLAYER_ENTERING_WORLD = afbar.ARTIFACT_XP_UPDATE

afbar.UNIT_INVENTORY_CHANGED = afbar.ARTIFACT_XP_UPDATE

So whenever you change the artifact or login/at loading screen ARTIFACT_XP_UPDATE is called regardless.

take a look here

There is another event ARTIFACT_UPDATE. This fires after P_E_W when the client first gets artifact info, as well as whenever your artifact changes (relics equipped, traits bought, etc), or if you receive a new artifact.

Thanks all for the kind replies.

As usual this forum is so helpfull.
Thanks all.

@Gethe
ARTIFACT_UPDATE after PEW is caused by addons. You can't rely on it.
