Convert coordinates from memory to ingame coordinates?

[radarlove]

Hi,

My tool currently reads X/Y coordinates from memory which are very different from the X/Y coordinates in-game.

Is there any algorithm to be used to convert the memory coordinates to client coordinates?

(Btw; already tried search function, didn't come up with very useful stuff)

thx in advance,

it's been a while since I coded anything for wow, but iirc the in-memory co-ordinates are continental (i.e. for the whole continent), the add-on displayed co-ordinates are zone co-ordinates (i.e. for the zone you are in)

as far as I recall, you can just take the offset from continent to zone and subtract it to localise for the zone.

What exactly do you mean by "take the offset from continent to zone"?

Each zone has a bounding box defined in the WorldMapArea DBC iirc.

Know that, you can calculate the relative ([0, 1] x [0, 1]) position in the zone.

Ok, so linear extrapolation should do the trick.
I'll go check on the "WorldMapArea DBC", what exactly is a DBC? . Can this actually be read out of memory or are these static boxes per zone?
And, if someone happens to have some lines of code, I would greatly appreciate it (thx).

thx for replies/effort,

An additional question: can anyone advise me a good MPQ reader? Cause I understand that is needed to read the DBC's?

[Robske]

You can either extract the DBC's from the MPQ's or read them from memory, Apoc has posted a way to do the latter several months ago.

Take a look at API GetCorpseMapPosition - WoWWiki - Your guide to the World of Warcraft

thx for the info!

Any MPQ Reader you would recommend? I just googled MPQ Archives - Downloads (MPQ Archives)... that a good one?

I use Ladik's MPQ Editor, and I've had no problems opening/extracting files from WoW MPQs (available from Google).
You'll also need a DBC editor. I use Bitforge's DBC Editor, but I don't remember where or when I got it and Google isn't being very helpful. You'll have to search and try out different DBC editors until you find one you like.

Thx for this info. Just one additional question: Which file do I need to access for the WorldMapArea.dbc?

Which file do I need to access for the WorldMapArea.dbc?

On 3.3.5a it is in Data/enUS/Patch-enUS-3.MPQ

Other than that you'll have to search for it

You also might find http://www.pxr.dk/wowdev/wiki/index....rldMapArea.dbc useful. Or perhaps horribly out of date....
