Coordinate Translation

[mcpickle]

Goal: Convert long numerical coordinate values (-4785, 29 received from memory into the coordinates used in-game by players (45.3, 76.7).

I've heard that there is no one formula for this conversion due to the coordinates being zone specific and because of this I should map out the physical boundaries of a zone and use basic math to translate the coordinates.

For all practical purposes my coordinate system is working just fine. This is purely a cosmetic thing. So before I waste any more time on this issue I figured I'd check to see if anyone has discovered a better solution.

Appreciate any help!

Why not open up WoW and find out how it does it?

WowClientDbRow zone = WoWGame.UI.GetWorldMapAreaShown();
var a = new Vector3(zone.GetField<float>(6), zone.GetField<float>(4), 0f);
var b = new Vector3(zone.GetField<float>(7), zone.GetField<float>(5), 0f);
var realPoint = new Vector3(a.X + y * (b.X - a.X), a.Y + x * (b.Y - a.Y), 0f);

I'll let you figure out the math for the other way around; it's simple.

Not always correct. (As I showed you with the Barrens area)

                        Database.WorldMapAreaRecord CurrentArea = Database.WorldMapArea.Get((Int32) Core.ObjectManager.ZoneId);
                        if (CurrentArea != null)
                        {
                            Single tX = CurrentArea.A.X - (CurrentArea.A.X - CurrentArea.B.X) * args.Location.X;
                            Single tY = CurrentArea.A.Y - (CurrentArea.A.Y - CurrentArea.B.Y) * args.Location.Y;
                            Single tZ = Me.Location.Z; // the game

                            Teleport(new WoWPoint(tX, tY, tZ));
                        }

In what situations would this fail? I've been using it extensivly for quite some time now and have yet to end up in limbo.

Edit: few days soon, but 911 posts!

For whatever reason, in the Barrens, the bounds for the area are literally, 1/2 of Kalimdor. I'm not sure why, but that's just how it is. If you check in game; the coords properly go from 1-100 (roughly) within the zone. The WorldMapArea bounds for the Barrens, are definitely not within that area. Plus; WoW does a lot of transformations on the location according to what I've found. (Excluding the BElf/DR/etc starting area transforms, and dungeon map transforms)
