Polygon problem

[wog]

I want to make polygon but have problem

 

Uncaught TypeError: Cannot read property '0' of undefined

 

this.points = this.groundGenerator();        

this.poly = new Phaser.Polygon(this.points);

this.graphics = this.game.add.graphics(0, 0);        

this.graphics.beginFill(0xFF33ff);

this.graphics.drawPolygon(this.poly.points);        

this.graphics.endFill();

 

 

groundGenerator: function (){

        var points = [];

        for(var x=this.getRandomInt(50, 150); x<1024; x+=this.getRandomInt(10, 100)) {

            points.push(new Phaser.Point(x, this.getRandomInt(0, -150) + 10));

        }

        return points;

    }

 

Thanks

That solved. Just updated Phaser from 2.0.1 to 2.2.1
