RealID list

[cormanthor]

I wrote an addon whose purpose is to display the name, toon name, and level of all of my RealID friends that are currently online. It works perfectly with one exception: all the data is not present at the event-firing. This causes an error about concatenating nil fields (even though I assigned defaults) which is unrecoverable without a reload.

What would be the best method to delay the EventHandler script for 1-2 seconds? Or better yet, is there a better set of events to monitor?

-- People Detector for CormanthorUI
 
-- Create the color table (redundant, but necessary)
local colorScheme = {
    death_knight = "C41F3B",
    druid = "FF7D0A",
    hunter = "ABD473",
    mage = "69CCF0",
    monk = "558A84",
    paladin = "F58CBA",
    priest = "FFFFFF",
    rogue = "FFF569",
    shaman = "0070DE",
    warlock = "9482C9",
    warrior = "C79C6E"
}
 
-- Create the frame and listen to events
local cormPD = CreateFrame("frame", "PeopleDetector", Minimap)
cormPD:SetSize(200,100)
cormPD:SetPoint("TOPRIGHT", Minimap, "TOPLEFT", -10, 0)
cormPD:RegisterEvent("PLAYER_ENTERING_WORLD")
cormPD:RegisterEvent("BN_FRIEND_ACCOUNT_OFFLINE")
cormPD:RegisterEvent("BN_FRIEND_ACCOUNT_ONLINE")
cormPD:RegisterEvent("PLAYER_FLAGS_CHANGED")
local text = cormPD:CreateFontString()
text:SetFont("Fonts\\FRIZQT__.TTF", 10, "THINOUTLINE")
text:SetPoint("TOPRIGHT", cormPD)
text:SetJustifyH("RIGHT")
local myRealm = GetRealmName()
 
-- List the first name and toon name of all RealID friends
local function Event_Handler(self, event, ...)
    local online = select(2,BNGetNumFriends())
    local list = ""
    local friendName = ""
    local toonName = ""
    local toonClass = ""
    local toonLevel = ""
    local toonRealm = ""
    for i = 1,online do
        friendName = select(2,BNGetFriendInfo(i)) or "UNKNOWN"
        toonName = select(4,BNGetFriendInfo(i)) or "UNKNOWN"
        toonClass = gsub(strlower(select(8,BNGetFriendToonInfo(i,1)))," ","_") or "priest"
        toonLevel = select(11,BNGetFriendToonInfo(i,1)) or 0
        toonRealm = select(4,BNGetFriendToonInfo(i,1)) or myRealm
        if toonRealm == myRealm then
            list = list..friendName
        else
            list = list.."|cff0080FF"..friendName.."|r"
        end
        list = list.." (|cff"..colorScheme[toonClass]..toonName.."|r "..toonLevel..")\n"
    end
    text:SetText(list)
end
 
cormPD:SetScript("OnEvent", Event_Handler)

Which event are you currently using ? I couldn't see it listed in there.

If you aren't already trying it try BN_CONNECTED or BN_SELF_ONLINE.

It's above the handler:

cormPD:RegisterEvent("PLAYER_ENTERING_WORLD")
cormPD:RegisterEvent("BN_FRIEND_ACCOUNT_OFFLINE")
cormPD:RegisterEvent("BN_FRIEND_ACCOUNT_ONLINE")
cormPD:RegisterEvent("PLAYER_FLAGS_CHANGED")

Oops, thanks Waky, totally missed those lines.

Second return of BNGetNumFriends is not the right number you want to iterate over the friendlist even if you only want those who are online.
You need to iterate over all friends (first value) and then check against the online flag if you need this info.

It actually does work well (in this regard), because Blizzard auto-sorts the online ones first, granting them the lowest index values.

I'm not sure about the other events listed above, as there doesn't seem to be much documentation on them. But I will give them a try this evening and post the results (and final code if it is fixed).

Thanks for the help and suggestions so far everyone!
