"sulien" is shyllien, and actually materials doesn't cover it.
(materials is good to have though, if you like life skills. item will pick up a lot of stuff though i don't recommend it)
autobot should find what you're looking for, all of the dollbags have it in their StringID
example, this is what i use for my young tarlach dollbag:
If the move_random speed is set too fast I find that they break after awhile.
I've set mine to use between 500 and 1500ms delay, and they never break.
I also have pet_shuttle_item at 500-500
it's in aidescdata_autobot_vocaloid.xml though, not race.xml.
(also if you don't like them trying to pick up other people's stuff that's pretty far from you, you can lower the max_radius value to something reasonable)
Per your instruction I changed it to look like this, the dolls still get stuck after a while. One thing I do want to point out is that the move_random line was commented out before I edited it.
Does it look right to you? If you don't mind, can you attach ur aidescdata_autobot_vocaloid.xml so I can try it out lol?
