Not in the constructor. During the constructor of a Sprite it has not yet been added. What you need to do in your constructor is:
this.addEventListener(Event.ADDED_TO_STAGE, handleAddedToStage); And then in handleAddedToStage() method of your class this.stage will be valid. If you need to know when you're removed from the stage (which, AFAIK, won't happen to your root class in an AS3 project, but will happen to other classes, potentially) is to listen for REMOVED_FROM_STAGE. If you wanna know when this.parent is valid, listen for Event.ADDED. Troy. On 5/31/07, Alex Harui <[EMAIL PROTECTED]> wrote:

I was using a hackish timer to do the job. However, your solution doesn't work from within the class that I create (haven't tried outside yet). Is there a way to do this all from inside the class I am using, or does the event listener have to sit outside the class? Really, I think it would have been better, but maybe it's not even possible to make the constructor function of classes automatically have access to the stage object on instantiation? Also, to trap keyboard events the only way I could make it works is the following: stage.focus = this.parent; this.stage.addEventListener(KeyboardEvent.KEY_DOWN,keyHandler); this.stage.addEventListener(KeyboardEvent.KEY_UP,keyHandler); --- In [email protected] <flexcoders%40yahoogroups.com>, "Michael Schmalle" <[EMAIL PROTECTED]> wrote: > > Hi, > > The stage object does not get defined until right at the end of the players > init cycle. > > Try listening to the Sprites Event.ADDED_TO_STAGE event, then access the > stage object. > > Peace, Mike > > On 5/31/07, patricklemiuex <[EMAIL PROTECTED]> wrote: > > > > Dear Actionscript wizards: > > > > I have an all as3.0 project. > > > > I can never seem to access the stage object (I've posted several times > > and never can get any appropriate solutions)? i thought this was > > automatic with every class that extends sprite...
