Draggable - know when drag element hits bounds

I'm wondering if there is a way to know if the draggable element hits the bounds i have defined for it?  I would like to shoot off a function or some code when it hits the edge of the bounds area.

Hello TopGun121

 

Have you looked into the hitTest() method:

Also look at this Topic on hitTest() method:

 

http://greensock.com/forums/topic/15019-collision-detection/
 

//checks if at least 30% of the element is overlapping with the other element:
if (this.hitTest("#element", "30%")) {
   // code stuff here
}

:)
