Well the thing with the sudden turns is if you look at the profile inside the profile creator (you can load existing ones) is that if it's pathing to another node across the way it might intersect with another path and that other path will be the route the bot chooses to go causing it to take a direct turn onto another selected path.I tested some of these profiles and a lot of them are really Jerky and obviously botlike, i'd suggest smoothing paths and writing profiles that don't have sudden turns. When I'm making a profile i find it better to have long banked turns than sudden ones.
I think that it could be smoothened out to be a bit more gradual however I'm not too sure how I can achive this with the waypoints method I used.
You are more than welcome to help correct the profiles you feel are jerky and commit / PM them to me and I'll update my list. Like I said this was done just to get my leveling done and figured I'd share since I spent a decent amount of time making sure they are "AFKable" to an extent.
Smoothing out the curves is something that is on my todo list.
Could you not just try and lower the node distance to 1? Or .5? The files would start to get pretty huge and probably a little laggier, but it'd be the closest thing to a smoother line.
