recording human players movements and allowing bots to explore unvisited areas is an approach which worked fine in joebotxp
that bsp stuff is really a lot of work, and - using the wayfinding algortihms appropriately - waypoints behind doors, and in unreachable places should not present a problem at all, although some waypointers might think that way, cause otherwise they'd be jobless
it's really a shame that HL2 isnt really nice for botcoders, maybe I should start looking for some other platform ... somehow would be fun again I suppose, havnt done anything on that topic for about a year
