Hi!  
My first and ambitious post on kirupa… I’m curious to find out!  
Here’s my actionscript problem (high newbi-ness):

if you have the FLASHMX random moving cones tutorial on this site, how would I expand that movie to do the following:  
If two cones hit each other (hitTest): they show a flash and then go on moving randomly, but now sticking together (one after the other, horizontally).

With hitTest you always need 2 different movies it seems, while the cones from the tutorial are just all the same instances. So I don’t know how hittest can monitor say like 40 different cones at once to see if they hit another one, and then do the behaviour i talked about…

please enlight me with examples and tips :sigh:
