Hi trooper119,
i guess i would be happy to get my grazing wildebeasts to herd/flock while a pride of lions prey on them.
i not sure am i on the right direction, i'm in dilemma whether to use c_move to move the wildebeast or to use vec_accelerate.

i found some wdl file on herding, but couldn't figure out how it is being done.

especially the scan_sector.PAN = 360; part, scan_sector is a var and it using .PAN.
