I thought 'stage' was a top level global variable. Apparently it isn't so. Even importing 'flash.display.Stage' doesn't help. How to refer to the stage object?
I have seen 'stage' being used in some of senocular's tutorials too. Eg:
stage is no keyword, it's an attribute of all instances of DisplayObject and subclasses. When you write "stage.addEvent..." you're actually writing "this.stage.addEvent...". Again, it's only available in instances of DisplayObject.
