pixi.js

You can’t render geometry (Pixi.Rectangle), they are meant for calculations only. You can do the following instead: var graphics = new PIXI.Graphics(); graphics.beginFill(0xFFFF00); // set the line style to have a width of 5 and set the color to red graphics.lineStyle(5, 0xFF0000); // draw a rectangle graphics.drawRect(0, 0, 300, 200); stage.addChild(graphics); source
