Jonathan, that's actually legal in ActionScript. Ugly and misleading, but legal.
Pedro, change Mountain2 to this:
import flash.events.Event;
import flash.display.Sprite;
public class Mountain extends Sprite {
private var color1:uint=0x003300;
private var color2:uint=0x001700;
public function Mountain() {
addEventListener(Event.ADDED_TO_STAGE, stageListener);
}
public function stageListener(event:Event):void {
graphics.beginFill(color1);
graphics.drawRect(0,0,stage.stageWidth,
stage.stageHeight/2);
graphics.endFill();
}
You don't have a reference to the stage until the object is actually
added -- using an event listener to wait until you're added to the
stage solves the problem.
