i’ve seen this a million times,  
i just can’t think of any examples off the top of my head.

I’m trying to do this.  
[http://www.kirupa.com/developer/mx/followease.htm](http://www.kirupa.com/developer/mx/followease.htm)

but,  
i want it so that the object that follows my mouse is on a track,  
so that it only moves up and down according to the y-coordinates of my cursor.

i hope that made sense.  
anybody know where i can find a tutorial for that?  
:ne:  
thanks people.
