Navmesh question

[Pandu91]

Hi,

Can anyone help me with reading navmesh (.tile) files? Maybe Informations about the Filesystem or is there already a working reader source available? My Navmesh files does hae TESM Fileheaders, I have attached one.

It would be nice if yomeone could help me.

File-Upload.net - 1_1_1.tile

Thanks for your help.

Best regards

Maybe you should search there, where you get those mesh files :P I haven't heard aboud this "TESM" format(which could also be MSET, depending on the format :P) ... as well as google.
Without further information I doubt someone can/will help.

Hi,

these are the mesh files from: MMOCrawlerbots | WoW Bot Forum

If someon has other working and complete mesh files I would take them instead.

why don't you try to create you own files instead of using others?

Hi,

I already tried that but I didn't find any good explanation how to convert the *.adt to the navmesh files.

I would ask the author of whatever application produced the files you're trying to read. I personally have never heard of it.

THE TESM is only the Magicheader, I think navmesh should have VAND headers, I can find the VAND header in this file but I don't know how to kick out the TESM stuff

A good explanation? Well, even when you were able to parse the navmesh... what do want to do with it? Maybe we could help you with parsing the data, but are you able to write pathfind algorithms that may work with the data from those navmeshes? It would be easier for you to start from scratch (or atleast using some opensource stuff, like Wowmapper and Recast => Detour).

Currently I'm writing my own tool to convert adt (+wmo and mdx data) into object files which can be used in recast. So I think I know what I'm talking about when I say: this is not a trivial job. Don't try to use the files from an existing project without knowing how to create them. Just imagine they stop providing their meshes to the "public"...

I was able to write code to use the unmanaged DLL from https://github.com/tomrus88/capek to use it in C#, it is working but only with the Sample Meshfile. So it is no problem if I have a working navmesh file.

But of course you've got a point it might be better to start from scratch.

I could look into the sources of wowmapper etc to write working code (cause all those tools are outdated.) But do you have another idea how I can start with writing my own code? Are there good docs about the fileformats available? I think the first step should be convert a single .adt to .obj.

Parsing the a ADT file is quite simple, and yes, there are good docs (if not awesome :P) about the fileformats:

Good luck!
