    copied!<p>Is it possible to access an event handler from one class to another and if so how? I want to remove an event handler from an object. I have two objects say objectA and objectB. Inside objectA how can I remove an event handler for objectB. This is what I tried but it does not work.</p> <pre><code>MovieClip(root).objectB.removeEventListener(MouseEvent.CLICK, ready); </code></pre> <p><strong>Details:</strong></p> <p>I have two classes called Guest and Guest2. I wanted to know is it possible to remove an eventlistener in the Guest class from Guest2 class. Below is the full code. Note: Both class have exactly the same code</p> <pre><code>package { import flash.display.MovieClip; import flash.events.Event; import flash.events.MouseEvent; import flash.filters.*; public class Guest extends MovieClip { var walkSpeed:Number = 5; var oldPosX; var oldPosY; var myGlow:GlowFilter = new GlowFilter(); public function Guest() { addEventListener(MouseEvent.MOUSE_OVER, addGlow); } function addGlow(event:MouseEvent):void { filters = [myGlow]; addEventListener(MouseEvent.MOUSE_OUT, removeGlow); addEventListener(MouseEvent.CLICK, ready); } function removeGlow(event:MouseEvent):void { filters = []; } function ready(event:MouseEvent):void { filters = [myGlow]; stage.addEventListener(MouseEvent.MOUSE_DOWN, walk); removeEventListener(MouseEvent.MOUSE_OUT, removeGlow); **MovieClip(root).Guest02.addEventListener(MouseEvent.CLICK, walkTo);** } function walk(event:MouseEvent):void { oldPosX = parent.mouseX; oldPosY = parent.mouseY; rotation = Math.atan2(oldPosY - y,oldPosX - x) / Math.PI * 180; filters = []; stage.removeEventListener(MouseEvent.MOUSE_DOWN, walk); stage.addEventListener(Event.ENTER_FRAME, loop); } function loop(event:Event):void { var dx:Number = oldPosX - x; var dy:Number = oldPosY - y; var distance:Number = Math.sqrt((dx*dx)+(dy*dy)); if (distance&lt;walkSpeed) { // if you are near the target, snap to it x = oldPosX; y = oldPosY; removeEventListener(Event.ENTER_FRAME, loop); } else { x = x+Math.cos(rotation/180*Math.PI)*walkSpeed; y = y+Math.sin(rotation/180*Math.PI)*walkSpeed; } } **function walkTo(event:MouseEvent):void { _Guest02.removeEventListener(MouseEvent.CLICK, ready); }** } } </code></pre>
