Heyyo,
Heh, ladders... if you think waypointing ladders with PODbot is hard, try it with RCbot. before I finally found the right noclip_mode console command, I would find all these neat little ways I could work around the ladder waypoints. One good one I found was to place norm waypoints 1 foot away from the ladder, and so bots would (usually) leap onto the ladder, n' climb up, sometimes in pairs!
And now? I know how to use noclip mode properly, so I've been going back, n' fixing the majority of my ladder waypoints n' properly waypointing objective waypoints so bots could pass all levels. (To do this I just placed objective waypoints after the level tansition parts so bots would try to make it to the objective waypoints, but end up just passing the level, smart eh?
)
Which reminds me, gotta do a post in the RCbot forums concerning a new idea on how to handle ladder waypoints, and that he did fix bots so they don't shoot at the tentacles when they're underground... but they don't shoot at them at all now, lol, which's pretty funny cause they'll run aboot all happily... until a tentacle starts slamming the ground infont of it.
