Hi all,

I've just started transitioning to AS2 (so go easy on me), and have a question about a game I'm building...

I have a "Baddie" object which handles a baddie on the screen, and when one gets killed, and has finished it's death animation, I'm running a method within the Baddie object called die() which deletes the associated movieClip, and then is meant to delete the baddie Object itself, but it doesn't seem to work....

   public function die():Void {
       trace ("deleting");
       removeMovieClip (baddie_mc);
       delete this;
       trace ("Am i still alive?");
   }

The movieclip is successfully removed, but I would expect the second trace "Am I still alive" NOT to appear as the object has been deleted, but it does. I read somewhere that it is illegal for an object to delete itself - is this true?

Is there another easy way of doing this?

Thanks! :o)

Mark

No sir, objects do not delete themselves. For my projects i have an external destructor function, for instance:

//enemy class
class Enemy{
   private var creator:Object;
   private var myClip:MovieClip;
   public function Enemy(c:Object){
      creator = c;
   }
   public function death():Void{
      playSound(explosion); //for instance
      removeMovieClip(myClip);
   }
   public function destroy():Void{
      creator.destroyEnemy(this);
   }
}

//whatever deploys the enemies
var enemies:Array;
function addEnemy(){
   enemies.push(new Enemy());
}
function destroyEnemy(e:Enemy){
   for(var i = enemies.length;i--;){
      if(enemies[i]==e){
         enemies[i].death();
         enemies.splice(i,1);
         break;
      }
   }
}

Didnt give this much thought so its probably not brilliant, but you get the idea
