[Project] WoWMap (Navmesh)

[miceiken]

Hey guys, I want to present something I worked a bit on last fall. It's mainly an ADT-parser for the WoW game files using the new CASC-archives, intended for use in navmesh generation.

I've got the rough parts figured out, and it handles most chunks find, including terrain, liquid, wmos and doodads.
I'm not a 100% on whether it generates the correct coordinates or if it is flipped, as it appears fine in Recast preview, but hasn't been tested with WoW (although I'm fairly sure it's fine). There are some issues regarding WMO and Doodad rotation, some of it is right, and some of it is wrong. I have yet to work out the quirks.

For navmesh generation and pathfinding I was going to use SharpNav, which is a promising .NET project that aims to mimic the Recast/Detour API.

Please note that the project is in no way finished and still needs a lot of work. I just wanted to share it because I've lost interest, and someone might have use for it.
AFAIK, it should be compatible with WoD.

Feel free to fork and contribute, or use this in your projects. Let me know if you make anything cool!

Looks good! + Rep

Looks promising.
Against which wow version was it made? 3.3.5a?

WoD back in November, not much should have changed, so I'm fairly sure it still works.

Good luck with this project! I think the last working open source mapper we've had was Bananen's so it's great to see that people are still interested about this!

PS: Can't rep you because "You must spread some Reputation around before giving it to miceiken again.".

Thanks. I love to see navigation code in C#.

Let me know if anyone has done anything cool with this project. The forks are dead, but I suspect some might clone and only do local changes

Funny you brought that topic back up, I actually cloned the WoWMap project and did a few changes in the past few days, mainly to make the "WoWMapRenderer" work using the new DB2 files and stuff.

I'm having issues on the WoWMapParser & NavMesh part though, after editing it to skip 8 bytes if Magic was "MD21" on model files, I've got it to work at least partially and render maps like this : Imgur: The magic of the Internet
Problems arise when I try to use "FindNearestPoly", it seems that unless I put the extents (default 5f/5f/5f) to a really high value, it won't find any close enough poly and it looks like I'm missing something. Do I need to edit the MD20.cs or M2.cs in any way to reflect recent changes in the file structure or ... ?

Been stuck on this for a few hours now, would love to get some input on this

Yeah, the navmesh part was the end goal, but something I never really finished. Lost interest after a while. Seems you've already gotten further at debugging it than I ever did - in other words - I would not trust the navmesh code to be correct. As for the parser part, it was written back in WoD (I think?), so it would make sense that some file formats changed.

If you're interested, maybe look into GitHub - wowdev/WoWDBDefs: Client database definitions for World of Warcraft for file definitions and generation - if not, most of the formats are probably up-to-date on the wiki wowdev

Either way, nice to see someone playing around with it

GitHub - Vegoo89/AdtToObjParser: Adt to obj parser for WoW Legion

It's written horribly, I didn't care about code standards back then but it was able to parse all legion maps in around 8 hours using 4 cores.
No idea about changes that were introduced in BFA but maybe you can find something useful here
