Would people be interested in revamping the AI routines for NPCs? In keeping with originality, I suppose it wouldn't feel the same to play, but the AI is pretty poor. That, and it might be nice to have NPCs that don't run into walls and forget they're being attacked.
Anyway, I'm a fairly able programmer, though my AI experience has mainly been neural nets and agent systems, rather than scripts, but I'll give it a bash if its something people are interested.
Ok, that sounded fairly forward, but you get the idea.
I'd opt for a complete rework if you're hoping for a major improvement. Just dump all the old code and start afresh. (though this is not entirely possible due to the need to implement existing pawn functionality)
This is true, blueneptune is currently working on the AI (among other things) for DXR, however, we welcome any help we can get, especially on the programming front.
