Two returns for GetCurrentMapAreaID()

[myrroddin]

I was testing out some /dump commands, one of which was GetCurrentMapAreaID(). It had two return values, the mapID and a Boolean. Does anyone know what the Boolean is supposed to tell us? Neither Wowpedia or Wowprogramming have this in their docs, and the 6.x changes on Wowpedia don't mention changes to this API.

-- at my Garrison
/dump GetCurrentMapAreaID()
>> 971, false

Yep

local mapID, isContinent = GetCurrentMapAreaID();

A great place to find out what the API is doing is to dump the BlizzardInterfaceCode from WoW itself. In this case you see examples in QuestMapFrame.lua and WorldMapFrame.lua for this call with both return values.

I have a fork of Tekkub's wowuisource, I just search through that for functions/vars etc Sometimes I get lucky, sometimes I really don't :P

Okay, good. I found it in WorldMapFrame.lua and QuestMapFrame.lua.

Best I can tell is that isContinent is false for non-Cosmic and non-Azeroth maps, possibly non-Maelstrom. Based on Blizzard's undocumented code, I am having a hard time figuring out why they have the second return.

According to QuestMapFrame.lua, for example, they are using that return to determine if quest objectives should be shown or not.

Thank you Seerah. I need to test, but I'm beginning to suspect that isContinent will be true if the currently viewed map has quest objectives. Unless you had zero quests in your log, or zero for a different zone, it will always be true for the greater map view.

For example, those of us leveling in Warlords would return true for Draenor, but what I was seeing at the time was that I had no quest objectives in my Garrison. However, I do have some now, and I certainly have some in various Draenor zones, so I'll test those.

Zoom out to the cosmic map, and it will be true, because Draenor as a whole fits into the cosmic map.

I think you've put me on the right path.
