Astrolabe

Astrolabe is an embeddable library for placing icons on the Minimap, and on World Maps. Icons that are placed on the Minimap using Astrolabe are placed in a special buffer and their positions are continuously updated for player movement, based on the world map coordinates provided when the icon was initially placed. Icons remain in this buffer until they are removed.

Astrolabe also provides functions to compute the in-game distance between two points and translate a point from one zoom level of the map another.

    I have a hacked up version of TomTom/Astrolabe that I have made work in both live and beta, mostly.

    Please fell free to use it or not as necessary or to ask any questions.

    I'll be updating the zip as fix further bugs.

    While trying to use TomTom in WoD:

    The GetMapContinents() and GetMapZones() no longer return just a list of the names of the continents or zones, but return pairs of map ids and the names.

    I was playing WoW and got this pop-up:

    There seems to be an issue with Astrolabe getting the proper location for the micro-dungeon faction hubs in Vale of the Eternal Blossom - at the very least, for Shrine of Two Moons.

    When tracking a single point, the direction seems to be off by about 30 degrees while in Shrine of Two Moons - however, upon stepping outside (Vale of the Eternal Blossom), it will immediately calculate the correct direction.

    Just my two cents...

    The CPU usage of Astrolabe (on CPU profiling) is relatively high, and I believe the most loading is contributed by Astrolabe:OnUpdate. May you consider to lower the frequency of running the actual updating code? For instance, to me every 0.1 sec is smooth enough, every 0.25 sec is a bit zigzag but still acceptable.

    Please note that as of the most recent patch to the MoP beta, Astrolabe rev 146 or higher is required.

    @Vulpem: Go

    Turns out there was a bug on line 203 which allowed your calculation to proceed to the point of error. Attempting to calculate a distance between Azeroth and Outland should simply return nil since there is no common reference for the two "worlds."

    Edit: I will likely post a new beta with the fix in the next few days. In the meantime, the fix is available in the Subversion repository.

    Thanks for updating this helpful library

    I'm getting the following error whenever I path through ComputeDistance using one map within the Outland system (530) and one in Azeroth: Astrolabe.lua:215: attempt to index local 'cont2' (a nil value)

    It seems to be looking for WorldMapSize[0][530], which is nil.
