Add polygon to container

[fire7side]

I can't seem to add a polygon to a stage.  Probably something simple.  I made just a square to see if I messed it up, but same thing.  When I comment out the addChild line for the poly it works.  When I uncomment it says: 

Uncaught TypeError: t.emit is not a function

 

var scn4 = {
getStage:function(){
	this.name = "Scene";
	this.polyPts = [0,0,0,100,100,100,100,0];
	this.poly = new PIXI.Polygon(this.polyPts);
	this.stage = new PIXI.Container();
	//
	this.bg = new PIXI.Sprite(
	PIXI.loader.resources["assets/img/dogRoom.jpg"].texture
    );	
	this.test = new PIXI.Sprite(
	PIXI.loader.resources["assets/img/test.jpg"].texture
    ); 
    this.stage.addChild(this.bg);
	this.stage.addChild(this.test);
	//this.stage.addChild(this.poly);
    return this.stage;
}
}

var graphics = new PIXI.Graphics();
graphics.beginFill(0xffffff);
graphics.drawPolygon(this.polyPts);
graphics.endFill();

OK, thanks.  Do you set it to alpha if it's invisible?  I just want it to check for a mouse click on a sprite, not as something to see..

You can set "alpha" field of graphics object, but you have to switch interaction on/off separately from it.

I see now.  I don't need to add the polygon as a child.  I can just add it as a variable.  I just need to pass it the x,y coordinates from the sprite click to find out if it fell inside the polygon.  Then it doesn't cause an error.

Yes, hitArea is apparently an undocumented member of Sprite.  If buttonMode is set to true it only turns into a hand on the hitArea, not the rest of the Sprite with no code on my part.

@fire7side yep, that's exactly how it works
