Well, it mainly depends on what do you want to change, if you want to add, for example, new enemies or weapons you will need to modify the source code, but if you just want to make new graphics and levels or sounds or anything else, you can do it with any of the many existing editors out there.

What was Hexen made using? And where can you get the Source Code?

Hexen is (I think) written in C++ might be C though. You should be able to find the Source Code by searching for in on Google or somthing. If you can't find it tell me and I'll e-mail you the version I downloaded.

Or you could get the Source Code for a Hexen source port and use that instead, I personallyrecommend Vavoom because of Janis' great support.

We got it in Raven Files in File Front too, but I can't seem to make the link work...



Sorry

Do you think you could make it so Kmod can be run off a different port, Vavoom maybe?

Not easily, we would have to basicly rewrite the whole thing on the Vavoom codebase.

So you won't?
