Unable to use LiquidArea from document class

[danissimo]

for

var flowingStage:LiquidStage = new LiquidStage (this.stage, 1024, 768, 1024, 768);

there's an error:

Access of possibly undefined property stage through a reference with static type Class.

for

var flowingArea:LiquidArea = new LiquidArea (this, 0, 0, 1024, 768, 0x666666);

there's an error

Implicit coercion of a value of type Class to an unrelated type flash.display:DisplayObjectContainer.

How should I point to main timeline and stage from doc class correctly?

Does your document class extend Sprite or MovieClip or some other DisplayObjectContainer? It must (that's a Flash requirement, not LiquidStage).

 

As for accessing the "stage", keep in mind that a DisplayObject's "stage" property will be null until the DisplayObject is added to the display list (like if you addChild() it to a Sprite/MovieClip that's on the stage). Again, that's just a Flash thing. You can sense when it is added by using an Event.ADDED_TO_STAGE listener. For example, in your document class's constructor you could do:

if (this.stage) {
   init(null);
} else {
   this.addEventListener(Event.ADDED_TO_STAGE, init);
}

function init(event:Event):void {
   this.removeEventListener(Event.ADDED_TO_STAGE, init);
   //NOW WE KNOW this.stage IS NOT NULL
   var flowingStage:LiquidStage = new LiquidStage(this.stage, 1024, 768, 1024, 768);
}

Stupid me! )

I got that init func in my class, but defined these variables before it!

Again, thanks a lot! You're the best! )
