How do I get Hit Detection to work in Flash?

Question

Ives tried many hit detections and none of them seem to work for me. I've tried hittest hittestobject hitarea. When my object (which is a or b movie-clip goes fully into c movie clip i want c to move 300 x direction. Does not need to be pin point detection just as long as its in the c movie-clip it works.

package  {

import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.events.Event;
import flash.media.Sound;
import flash.ui.Mouse;

public class bakingCake extends MovieClip {


    public function bakingCake() {
        // constructor code

        var object:MovieClip = new MovieClip;

        a.addEventListener(MouseEvent.MOUSE_DOWN,objectA);
        b.addEventListener(MouseEvent.MOUSE_DOWN,objectB);

        if (object.hitArea(c) == true)
        {
                c.x = 300;
        }           

        function objectA():void
        {           
            object = a;             
            object.addEventListener(MouseEvent.MOUSE_OVER,objectFun);
        }

        function objectB():void
        {
            object = b;
            object.addEventListener(MouseEvent.MOUSE_OVER,objectFun);
        }       


        function objectFun(event:MouseEvent):void
        {

            object.addEventListener(MouseEvent.MOUSE_DOWN,drag);
            object.addEventListener(MouseEvent.MOUSE_UP,sDrag);
        }
        function drag(event:MouseEvent):void
        {
            object.startDrag();
        }
        function sDrag(event:MouseEvent):void
        {
            object.stopDrag();

        }

    }
}

}

First of all: Is all this in the constructor function or is that just a copy paste error? What is `c`? What calls the hitArea function? Where are `objectA()` or `objectB()` called? — Rengers, Nov 16 '12 at 21:34

Did you tried getBounds() ?
I suggest condition:

if (c.getBounds(c.parent).containsRect(a.getBounds(c.parent))
 || c.getBounds(c.parent).containsRect(b.getBounds(c.parent))) {
    c.x = 300;
}

IMO the best way is check it triggered by ENTER_FRAME event, atached for any of object.

Question has been solved, Used a stage.addEventListener(Event.ENTER_FRAME, applicationloop); to constantly check collision – Liam Thomas Nov 17 '12 at 12:58
