I currently have a Nav that I am working on that will follow the mouse’s \_y position. I am wanting to have bounds set that keep the nav in between certain top \_y and bottom \_y, but am lost on how to do it.

I have tried applying the same techniques that I would to create bounds for a Dragging menu (define top and bottom bounds) but it didn’t work with the mouse position.

Here is the code so far that makes the menu follow the mouse:

speed = 25;  
menu\_mc.onEnterFrame = function () {  
target\_y = \_root.\_ymouse - this.\_y;  
this.\_y = this.\_y + (target\_y/speed);  
}

Any help would be appreciated.

## Thanks,

Michael

</div>

speed = 25;  
menu\_mc.onEnterFrame = function () {  
tempy = \_root.\_ymouse;  
if (tempy \> topvalue) tempy = topvalue;  
if (tempy \< bottomvalue) tempy = bottomvalue;  
this.\_y = (tempy - this.\_y)/speed;

}

Tried that and now it just stays at the top.

I tried defining a variable

topvalue = 33;  
bottomvalue = 663;

But no luck.

Did I do something wrong.

Thanks for the response!

This should certainly get you started.
