Random Movement in Flash MX

Hallo everybody,

my first post in this forum. So I finally made it. I downloaded on of the tutorials today and adjusted it to me needs, but I still got some problems. I am e newbie in flash, so please help me out on this one :wink:

The tutorial is called “Random Movement in Flash MX”. I have 10 duplicated movieclips on stage, which are moving randomly now for 20 sec. That’s because I sat an interval as well.
Now my problem. After these 20 sec the movieclips stop moving, but on some occasions they are overlapping. I don’t mind when there are overlapping during the 20 sec interval, but when they stop moving they should not overlap. How can I do that?

Cheerio
