[Tool] Navmesh Creator

[sPeC!]

Hello sPeC,

I had seen you Post about the Meshcreator. Now my question is how do you formated the mesh??It isn't like the Sampel Safe Funktion.... Thank you Verry much!

Ok, i forgot to say on what Detour format the navmesh was being created/saved. It's created on tile based format.

Cheers,

hi sPeC!
i've meshed the durotar map with your tool. but the problem is, that this tool cant mesh the part World\maps\Kalimdor\Kalimdor_40_32. I think, its some of the old world. Can you help me or modify the code to solve the problem ? thank you

Actually its not the old format, but in sPeC's defence: he is dealing with alot of crap in the old version of wowmapper. Progress on updating wowmapper to WoW v4.0 is good. I spent two days beside work and it's almost usable again. telcy: see this screen http://i53.tinypic.com/vammd.png where you can see Kalimdor_40_32. I hope I can release it by the end of the week. This time I will also try to include more samples, like displaying the terrain with Direct3D, generating navmeshes, etc. Cheers

I'am sorry telcy007, i currently don't have enough time to look into it because mid-term exams at school have started and have a bunch of school projects to do.. The good news are that Flowerew is updating his tool that is the main engine of this one, and it seems it will do what this one does but better...

It's looking great! Keep the good job.

Just a little update for you guys: I commited my current progress. It's no public release yet (hence no download), but it is able to parse kalimdor/azeroth new/old ...that's what I tested so far. WMO interior is not yet included either, but for testing purposes it's enough to get going with the new format. A sample is included which requires SDL and the DirectX SDK, it will display the geometry for a given area id (12 for Elwynn Forest for example). I will create a new thread when it's ready for the public which should be by the end of the week (I really try). Here's a screen of the current sample: http://img607.imageshack.us/img607/2556/wowmapper01.png Cheers

How do you even able to open 4.x mpq's with libmpq? And what about patch files (wow-update-XXXXX.mpq), i'm pretty sure libmpq doesn't support this...

[Flowerew]

I haven't had no problems so far. Listfiles seem to be ok, and even expansion3.mpq has been read without problems. Same goes for wow-update-xxxxx.mpq, so I dont know what you mean, TOM_RUS.

Basicaly libmpq has no support for mpq files used in 4.x wow client. For example wow-update-XXXXX.mpq doesn't store any directly usable data, only diffs from base mpq+all previous diffs (PTCH files). I'm surprised that libmpq can still open thise new files...

P.S. While trying to get your sample running, i've encountered few problems: 2 compile errors in VS2010 and 1 crash, what i've modified so far to fix them:

What tool are people using to extract ADT's from the MPQ ? I tried MPQEditor and it extracted "successfully" (I have files full of data), but I can't seem to read the header successfully. Basically, the MH2O offset is zero. Ideas ?

[namreeb]

I believe the MH20 chunk is optional. That is, it's not present in ADT chunks which do not have MH2O water.

Regarding your problem: It seems very strange, and I may have to get VS2010 to check it myself. Do you run 32 or 64 bit Windows? Have you had any hints as to when the crash occurs and why only 1 ADT seems to be displayed instead of a whole area? Any information would be greatly appreciated. Thanks for testing, TOM_RUS.

Do you even need them for this? I mean, I haven't really looked into them, but I guess the client will never process them itself - that would kill performance - but they're just input to the updater who will patch the respective MPQs.

It does process them.
If you leave the launcher running after a patch it says "Applying non-critical updates" (or similar, don't remember the exact phrase) which creates new mpqs in <gamedir>\data\cache where all the diffs are applied. There's a bunch of patch-base-XXXX.mpq there.
If you start the game before the lancher is finished it will do the same when a 'needs to be patched' file is loaded.
So to be sure you're getting up-to-date data you should either use an mpq lib that can handle the diffs, or read from the cache dir. Though on a side note I haven't checked if there is any updated terrain in the patches since 4.0, but there will eventually.

I'm running WinXP SP3 32 bit + VS2010. The crash was when parsing some ADT with _modnChunk.size == 0. I have no idea why only 1 ADT displayed, may be it's somehow related to VS2010...
