Me too haven't actually created any kind of waypointing code. You can look at RACC, he is using and autogenerating navmeshes like the official CS:CZ bot. The navmesh is not actually waypoints, it is movable areas where the bot can go and special places where he can camp or jump and such, the basic is generated at first map load, the other part is continue to be generating by the real players moves. One thing is for sure, it's not easy stuff.
