Make unit go around another one

I need to know how to make units move around another one, going in a circular patern, think about Lightning shield orbs

Another option is to make them move randomly around the hero

How do you do this???

I can't make the unit move around him, as it is flying and has no collision, so it will only go over the hero, and I don't want to do 9365026 orders

Maybe you can make a periodic trigger that makes them move around the hero. You should try move to position around the unit with polar offset.

I said no move to point

I don't want to do 360 order actions, and using a "Integer A" converted to real screw my game

ok sorry, but it wouldnt be any near 360triggs. Just 4 triggs, 4 points around hero.
