Instance Data Help

Hi guys,

I am completely new to the forums and only started looking at WoW addon development yesterday. Apologies if this post is in the wrong place.

Lua is new to me but I am familiar with other programming languages.

Ultimately, I am trying to develop an addon that does the following:
* Detects when the player enters a new zone, discovers what raids/dungeons are in that zone and (eventually) display a window that tells the player what uncollected transmog there is to farm in the those dungeons/raids.

So far I've just been getting familiar with the WoW API by printing stuff out from /reload - not going near UI yet.

I've been using this API reference: https://wowwiki.fandom.com/wiki/World_of_Warcraft_API

I can print out details about raids that the player is currently locked into but I'm struggling to find useful functions that provide info about the raids/zones.

Any pointers?

Thanks

You can register for ZONE_CHANGED_NEW_AREA and check the zone mapID by looking if the child mapIDs match any of your dungeon mapIDs
Otherwise you could hardcode a list of zones and their respective dungeons

Lua Code:

local dungeons = {
    [225] = true, -- The Stockade
    [291] = true, -- The Deadmines
}
 
local function OnEvent(self, event)
    -- entered new zone
    local uiMapId = C_Map.GetBestMapForUnit("player")
    local children = C_Map.GetMapChildrenInfo(uiMapId)
    for _, childMap in pairs(children) do
        if dungeons[childMap.mapID] then
            -- there is a raid/dungeon in this zone
            local zoneName = C_Map.GetMapInfo(uiMapId).name
            print(format("You entered %s (%d) which has %s (%d)", zoneName, uiMapId, childMap.name, childMap.mapID))
        end
    end
end
 
local f = CreateFrame("Frame")
f:RegisterEvent("ZONE_CHANGED_NEW_AREA")
f:SetScript("OnEvent", OnEvent)

Code:

> You entered Westfall (52) which has The Deadmines (291)

Other API you might want to look into:

You can also reference AllTheThings source code for their approach

This is fantastic, thank you so much for your help.
