    ( this is not a trivial problem at all )

    hi,

    this kind of motion is called flocking. there are fairly simple rules to put together and your boids will become autonomous. the original concept of boids was found and developed by Craig Reynolds and is available here: http://www.red3d.com/cwr/boids/.

    explainations and an implementation in actionscript were done by Keith Peters in his book AdvncED actionscript 3.0.

    the chapter concerning flocking is available here: http://books.google.fr/books?id=QuwsOHYA0p4C&pg=PA92&lpg=PA93&vq=flocking#v=onepage&q=flocking&f=false

    and the material ( classes and samples files ) are available here: http://www.friendsofed.com/download.html?isbn=1430216085

    note that other implementations exist, I’d recommend this one http://blog.inspirit.ru/?p=231
