Have random motion but ending at a set location?

Hi-

Say you have no more than (7) instances of a movie clip about to come on stage. Randomly changing the opacity, scale, and speed of each shouldnt be a problem right? There’s plenty of info out there on how to do that.

BUT, how do you get the instances to move randomly (and er, differently) each time the sequence loads, but have them end (or “land”) on the exact same spot each time?

ie - move around where ever you want for such-and-such specific amount of frames (or time), but make sure you stop right HERE when you get to the pre-determined end of the sequence.

Thoughts?
