Well, if you could decipher the maps, you could do a lot more than just removing walls, you could actually add/change stuff too, like a path that crosses a canyon or that makes it possible to walk thru walls without falling into eternity 

But yeah, great discussion, and great to know how you guys do it.  Anyone know how big-time commercial MMOs (i.e. WoW) do their maps?

So maps are stored in some sort of special binary format so as to be more un-hackable, right?  Since they're packaged with the client, map hacking has to be a major issue.

Hi,

First off let me say you have a cool game, and the music is great =)

I'm a lurker on these boards, and I also do a fair bit of C++ programming, so naturally I felt the need to take a peek at your code =)

I was looking around and frankly I'm having a hard time figuring out how maps are loaded.  There's common/bgloader/parser.cpp, which loads a map, but is that client or server side?

Basically what I'm trying to figure out is this: are maps loaded on the server and then transferred to the client, or does the client do all the loading itself?  If the latter, then it seems easily hackable, but I can't find any code that suggests server-side map loading.

Thanks,
