AS 3.0 : Primer on Global To Local

Today's Nyum-nyum codes will give you a head start with:

Constraining your object/mouse as a slider

You may copy and paste the following into the first frame of your timeline.

//1. import this flash class at the very top...

import flash.geom.Point;

//2. Define a 'constraining' area...I'm making a vertical slider, hence the following coordinates

var myVerRect:Rectangle=new Rectangle(50,200,1,200);

//3. Tell Flash to find the relative distance between your dragged object, in this case a slider handle and the point of origin

MyTextField.text=nameOfClipBeingDragged.globalToLocal(new Point(specifyXPOS,specifyYPOS)).y

//4. Start Drag Action

nameOfClipBeingDragged.addEventListener(MouseEvent.MOUSE_DOWN,Drag);

function Drag(myEvent:MouseEvent):void {

myEvent.target.startDrag(true,myVerRect);

trace(MyTextField.text);

}
