Hi there, CoCoNUT, seems to be a long time since you last tried PODBot, eh?
me and my LAN mates have been using that bot for more than a year now, and I can assure you that in general PODBots CAN lead hostages to the Rescue Zone.
However, there are some points to be considered:
1) sometimes it depends on the map. In some maps there are invisible obstacles for the hostages, such as staircases that don't work properly. Then you can see hostages desperately trying to climb that 20 cm stair...
2) the waypoints must be good!! IN PODBot 2.5 there was a flag called "FL_NOHOSTAGE" that could be added to any waypoint. It prevented bots from using that waypoint when leading hostages. But if the WP designer did sloppy work and forgot some of those flags... bad luck.
Oh, and another point: Some waypointers place the rescue zone waypoints badly. If this is the case, bots will lead the hostages to a point where they think the rescue zone is... and the hostages keep standing 5 cm away from the rescue zone until the game ends...
3) In bots based on the PB 2.6 source code (POXBot, [e]PODBot and PMB's PODBot plugin for MetaMod, among others), this flag is no longer present and it depends on pure chance if the hostages are rescued or not.
Fortunately, PM has recently updated his plugin and "re-introduced" a mechanism to keep bots with hostages from navigating through certain waypoints, and it works quite well!
If you browse the thread I opened in the MetaMod plugin forum, you'll see it, and there may be some interesting stuff for you to read as well...
