hey guys!

this is kinda hard to explain, but I’ll try!  
I’m making a MC follow the mouse in a bouncy way, take alook at the following example:

[example](http://www.deuxfemmes.dk/test/bounce.htm)

Now this works fine, but what I want it to do is, to stay inside the boxes, so it only bounces when I move the mouse over a “new empty” box! …how can this be done??

Here is my code:

```auto
onClipEvent(load){
velY = 0
acc = 4
dec = 1.2
}
onClipEvent(enterFrame){
currY = this._y
targetY = _root._ymouse
velY = (velY + (targetY - currY) * 1 / acc) / dec
this._y += velY
}

```

I’ve attached the .fla to!

For some reason I couldn’t open the .fla but I think I can give ya some ideas.  
Give the buttons some actions that when you rollover one it assigns a new value for currY  
For example  
the “thing”'s Ypos = 10  
You rollOver the second box which has a Ypos value of 40;  
on(rollOver) {  
\_root.currY = 40;  
}  
and that’s it!  
OH I almost forgot!  
add “\_root.” in front of each variable  
It’s good to store all the actions in \_root (the main timeline) (otherwize it won’t work too)

THX for your help dude! …but I still can’t get it to work the way it should, is it possible for you to add a tiny .fla so I could see exactly what you mean…? :nerd:
