Heyyo,
BTW, if you activate sv_cheats, you can do that "nav_generate" to create some nav paths for the ai, and then the "npc_create" to create npc's n' stuff.. but so far they don't do anything, I'm guessing cause of the removed ai scripts... now if there's some way to get them in HL2dm you can have a very cheap emulation of bot deathmatch... I just hope those ai scripts ain't in the .gcf files... I'll post later if I find them and implement them into HL2DM.
[EDIT]
Btw, if you use the "help" command before a command, it gives a small description of that command, it's usefull to help you figure out commands... too bad I can't find commands to generate ai scripts.
